Description
本発明は、植物生育土壌の少ない岩盤や法面等を緑化する法面用緑化資材、該法面用緑化資材を含む法面用緑化資材スラリー、該法面用緑化資材スラリーを用いる法面緑化工法、及び前記法面用緑化資材を用いて緑化した緑化法面に関するものである。 The present invention relates to a greening material for slopes for greening rocks and slopes with less plant-grown soil, a greening material slurry for slopes containing the greening material for slopes, and a slope planting using the greening material slurry for slopes The present invention relates to a construction method and a greening slope that has been greened by using the slope greening material.
露天採掘された鉱山の採掘後の最終残壁や、道路建設や土地造成等に伴って形成された岩盤や法面等は、植物生育基盤土壌が少ないか全く無く、その保護と景観を保持するために緑化用の芝や花卉類、樹木等を植生し、緑化が図られている。このような緑化工法の一つとして、バーク堆肥とピートモスを混合した土壌改良材に、植物の種子や高分子結合剤、肥料等を混合した植生基材を吹付機で法面上に吹き付ける吹付け工法が知られている。しかしながら、この吹付け工法は、植物生育土壌が多い法面への適用は有効であるが、植物生育土壌が少ない岩盤や法面に対しては、法面等の基盤安定材としての機能に欠けているため、法面上に吹き付けられた土壌改良材が降雨や風等により土壌浸食や飛散し、安定的に植物の発芽や生育させることが困難であり、緑化法面が得られなかった。 The last remaining wall after mining of open-pit mines, rocks and slopes formed with road construction and land development, etc. have little or no plant growth base soil, and preserve and protect the landscape For this reason, turf for planting, flowers, trees, etc. are vegetated and planted. As one of such greening methods, spraying a soil improvement material mixed with bark compost and peat moss onto a slope using a spraying machine with a vegetation base mixed with plant seeds, polymer binder, fertilizer, etc. The construction method is known. However, this spraying method is effective when applied to slopes with a large amount of plant-grown soil, but lacks a function as a base stabilization material for slopes, etc. Therefore, the soil improvement material sprayed on the slope is eroded and scattered by rain, wind, etc., and it is difficult to stably germinate and grow plants, and the greening slope cannot be obtained.
そこで、例えば、特許文献１には、木材パルプに叩解されてフイブリイ化されたピートモス、バーク等の有機質土壌改良剤をすき込むとともに、種子を混在させて乾燥し水分解性の薄層シートにした植生帯による緑化法面が開示されている。しかし、これらの植生帯を使用する法面等の緑化方法では、特に植物生育土壌の少ない岩盤や法面等で植生材料が降雨や風等による流失や飛散が減少するものの、植生帯の製造コストが高く、また、その植生帯を敷設する作業に多くの人手を要する問題があった。 Therefore, for example, in Patent Document 1, an organic soil improver such as peat moss and bark beaten by wood pulp is incorporated, and seeds are mixed and dried to form a water-decomposable thin sheet. A planting slope with a vegetation zone is disclosed. However, in the planting method using these vegetation zones, the vegetation material production costs are reduced, although the loss of vegetation material due to rainfall, wind, etc. is reduced, especially on rocks and slopes where there is little plant growth soil. In addition, there is a problem that a lot of manpower is required for the work of laying the vegetation zone.
一方、特許文献２では、耐土壌侵食性や種子発芽率の高い、バーク堆肥又はチップ材とケナフパルプからなる配合材を主成分とした植物生育基盤材を用いた緑化法面が提案されている。しかしながら、ケフナパルプは、特殊な資材であり一般には容易に入手することができない問題があった。 On the other hand, Patent Document 2 proposes a greening method using a plant growth base material mainly composed of bark compost or a compound material composed of chip material and kenaf pulp, which has high soil erosion resistance and seed germination rate. However, kefuna pulp is a special material and generally has a problem that it cannot be easily obtained.
このため、安価で、かつ、容易に入手可能な耐土壌侵食性の高いファイバー材を用いた緑化法面が求められていた。 For this reason, a greening slope using a fiber material that is inexpensive and easily available and has high soil erosion resistance has been demanded.
本発明は、安価で、かつ、容易に入手可能な耐土壌侵食性の高いファイバー材を用いた、植物生育土壌の少ない岩盤や法面等をも緑化する法面用緑化資材及び法面用緑化資材を含む法面用緑化資材スラリー、該法面用緑化資材スラリーを用いる法面緑化工法、及び前記法面用緑化資材を用いて緑化された緑化法面を提供することを課題とする。 The present invention uses a low-cost, easily available fiber material with high soil erosion resistance, and a planting material for slopes and a planting plant for slopes to plant green rocks and slopes with little plant-grown soil. It is an object of the present invention to provide a slope planting material slurry containing a material, a slope planting method using the slope planting material slurry, and a planting slope planted using the slope planting material.

Is a greening material for slopes, which is a water-soluble paper material.
水溶性紙は、容易に水に溶解し、緑化資材を水に分散したときに、緑化資材の分散状態を保持し、緑化資材を水に分散させた緑化資材が法面又は岩盤に吹き付けられて付着すると、緑化資材は法面等に定着して、適度な水分を保持し、種子の発芽を促すことができる。その結果、植物生育土壌の少ない岩盤や法面であっても、緑化法面とすることができる。 Water-soluble paper is easily dissolved in water, and when the greening material is dispersed in water, the greening material is kept dispersed, and the greening material in which the greening material is dispersed in water is sprayed on the slope or bedrock. When attached, the greening material will settle on the slope, etc., hold moderate moisture, and promote seed germination. As a result, even if it is a bedrock or a slope with little plant growth soil, it can be set as a greening slope.
また、本発明において、法面を緑化する法面用緑化資材は、水溶性紙材は、トイレットペーパ材からなる、法面用緑化資材である。 In the present invention, the slope greening material for greening the slope is a slope greening material in which the water-soluble paper material is a toilet paper material.
トイレットペーパ材は、安価、かつ、容易に入手可能である。 Toilet paper material is inexpensive and easily available.
本発明において、法面を緑化する法面用緑化資材スラリーは、法面用緑化資材１〜２重量比に対して、水８〜９重量比からなる法面用緑化資材スラリーである。 In this invention, the greening material slurry for slopes which greens a slope is a greening material slurry for slopes which consists of 8-9 weight ratios of water with respect to 1-2 weight ratios of slope greening materials.
本発明に係る法面用緑化資材スラリーを用いれば、植物生育土壌の少ない岩盤や法面であっても、容易に法面を緑化することができる。 By using the slope greening material slurry according to the present invention, the slope can be easily greened even on a rock or slope with little plant growth soil.
本発明において、植物生育土壌の少ない岩盤や法面を緑化する法面緑化工法は、法面用緑化資材スラリーを岩盤や法面の窪み又は亀裂内に吹き付ける緑化工法である。 In the present invention, the slope revegetation method for greening rocks and slopes with less plant-growing soil is a revegetation method in which a slope greening material slurry is sprayed into the depressions or cracks on the slopes and slopes.
本発明に係る法面用緑化工法を用いれば、植物生育土壌の少ない岩盤や法面であっても、安価で、かつ、容易に法面を緑化することができる。 By using the slope revegetation method according to the present invention, the slope can be easily greened even on a rock or slope with little plant growth soil.
また、本発明に係る法面緑化工法は、法面用緑化資材スラリーをコンプレッサと、エアーホースと、法面用緑化資材タンクと、吹付用ホースとを用いて岩盤や法面の窪み又は亀裂内に吹き付ける法面緑化工法である。 Further, the slope revegetation method according to the present invention uses a compressor, an air hose, a slope revegetation material tank, and a spray hose for a slope revealing material slurry. This is a slope planting method that sprays on the surface.
本発明に係る法面用緑化工法を用いれば、安価、かつ、容易に法面を緑化する作業を行うことができる。 If the slope revegetation method according to the present invention is used, the slope can be greened easily and inexpensively.
また、本発明に係る法面緑化工法は、法面用緑化資材タンクの内部に法面用緑化資材タンクの下部から圧縮空気を供給し、バブリングにより法面用緑化資材タンク内の法面用緑化資材スラリーを撹拌することを含む、法面緑化工法である。 Further, the slope revegetation method according to the present invention is such that compressed air is supplied from the lower part of the slope greening material tank to the inside of the slope greening material tank, and the greening for slope in the slope greening material tank is carried out by bubbling. This is a slope greening method including stirring the material slurry.
法面用緑化資材タンクの下部から圧縮空気を供給しバブリングすることにより、法面用緑化資材タンク内の法面用緑化資材スラリーを撹拌すると、法面緑化資材スラリーの懸濁状態が保たれ、確実に法面緑化資材スラリーを用いて法面を緑化することができる。 By supplying compressed air from the lower part of the slope planting material tank and bubbling, when the slope planting material slurry in the slope planting material tank is stirred, the suspension state of the slope planting material slurry is maintained. The slope can be surely greened using the slope greening material slurry.
本発明において、緑化法面は、法面用緑化資材が窪み又は亀裂に吹き込まれてなる緑化法面である。 In the present invention, the greening slope is a greening slope in which a slope greening material is blown into a depression or crack.
岩盤や法面の窪み又は亀裂に緑化資材スラリーが吹き込まれて法面緑化資材が付着すると、緑化資材の定着がより向上し、緑化が促進される。 When the greening material slurry is blown into the bedrock or the slope or crack of the slope and the slope greening material adheres, the fixing of the greening material is further improved and the greening is promoted.
本発明によれば、安価で、かつ、容易に入手可能なトイレットペーパ材を耐土壌侵食性の高いファイバー材として用いて、植物生育土壌の少ない岩盤や法面等を緑化する法面用緑化資材及びその法面用緑化資材を含む法面用緑化資材スラリー、該法面用緑化資材スラリーを用いる法面緑化工法、及び前記法面用緑化資材により緑化された緑化法面を提供することができる。 According to the present invention, an inexpensive and easily available toilet paper material is used as a fiber material having high soil erosion resistance, and a planting material for slopes that greens rocks, slopes, etc. with little plant growth soil. And a slope planting material slurry containing the slope planting material, a slope planting method using the slope planting material slurry, and a planting slope planted by the slope planting material. .
以下、本発明の実施形態を、説明する。 Hereinafter, embodiments of the present invention will be described.
先ず、図１に、本実施形態に係る緑化資材１３により緑化された緑化法面１１の模式断面を示す。緑化法面１１は、法面１２及び法面用緑化資材１３を備える。法面用緑化資材１３は、法面１２の表面に２〜１０ｍｍの厚みで付着している。 First, FIG. 1 shows a schematic cross section of a greening slope 11 that has been greened by the greening material 13 according to the present embodiment. The green slope 11 includes a slope 12 and a slope green material 13. The slope greening material 13 is attached to the surface of the slope 12 with a thickness of 2 to 10 mm.
法面１２は、露天採掘された鉱山の採掘後の最終残壁や、道路建設や土地造成等に伴って形成された岩盤や法面等であり、この岩盤や法面等の土質には特に限定されない。植物生育土壌が少ないか全く無い岩盤であってもよく、或いは、普通土、砂質土、粘性土、レキ混じり土等でもよい。なお、法面１２に窪み１４や亀裂１５があると、法面１２に付着した緑化資材１３が定着し易く、好ましい。また、法面１２の傾斜角度にも限定されず、任意であり、傾斜角度が０°の平坦地にも適用可能である。 The slope 12 is the final remaining wall after mining of an open-pit mine, and the rocks and slopes that have been formed with road construction and land development, etc. It is not limited. It may be a bedrock with little or no plant growth soil, or ordinary soil, sandy soil, cohesive soil, soil mixed with reki, etc. It is preferable that the slope 12 has a dent 14 or a crack 15 because the greening material 13 attached to the slope 12 is easily fixed. Moreover, it is not limited to the inclination angle of the slope 12 and is arbitrary, and can be applied to a flat ground having an inclination angle of 0 °.
法面用緑化資材１３は、種子２０〜７０重量部、肥料２０〜７０重量部、及び、ファイバー材４〜２０重量部からなり、そのファイバー材の重量比で半分ないし全量が水溶性紙材からなる。種子は、木本類、在来草本類、及び外来草本類の種子類を1又は数種類配合したものであり、肥料は、種子の発芽及び生育に適した化学肥料や土壌改良材等を配合したものである。一方、ファイバー材は、その重量比で半量まで水溶性紙を置き換えて、法面１２の直物生育土壌の有無、勾配の程度によって木質パルプを適宜配合することが好ましい。 The planting material 13 for slopes consists of 20 to 70 parts by weight of seeds, 20 to 70 parts by weight of fertilizer, and 4 to 20 parts by weight of fiber material, and half or all of the fiber material is made of water-soluble paper. Become. Seeds consist of one or several kinds of seeds of woody plants, native herbs, and exotic herbs. Fertilizers contain chemical fertilizers and soil conditioners suitable for seed germination and growth. Is. On the other hand, it is preferable that the fiber material is replaced with water-soluble paper up to half of its weight ratio, and wood pulp is appropriately blended depending on the presence or absence of the directly growing soil on the slope 12 and the degree of gradient.
ファイバー材は、緑化資材１３を水に分散させてスラリー化し、法面１２に吹き付けて付着させる際に、緑化資材１３をスラリー中で分散状態を保持させ、法面１２にスラリーが吹き付けられると、法面１２の表面に付着した緑化資材１３を法面１２に定着させ、適度な水分を保持し、種子の発芽を促す役割を担うものである。ここで、ファイバー材が水溶性紙材であれば、容易に水に溶解し、適度な長さの繊維が容易に得られる。また、水溶性紙材がトイレットペーパ材であれば、より安価、かつ、容易に入手が可能であるとともに、緑化資材１３の定着性も高く、適度な水分保持に優れており、より好ましい。 When the fiber material is dispersed by slurrying the greening material 13 in water and sprayed onto the slope 12 to adhere to the slope 12, the greening material 13 is kept dispersed in the slurry, and the slurry is sprayed on the slope 12; The greening material 13 attached to the surface of the slope 12 is fixed on the slope 12, holds appropriate moisture, and promotes germination of seeds. Here, if the fiber material is a water-soluble paper material, it is easily dissolved in water, and a fiber having an appropriate length can be easily obtained. In addition, if the water-soluble paper material is a toilet paper material, it is more preferable because it is cheaper and easily available, and the greening material 13 has a high fixability and is excellent in appropriate moisture retention.
なお、図１には、法面１２の表面に法面用緑化資材１３が定着し、一定期間が経過して、法面用緑化資材１３中の種子が発芽し、植物１６が生育し、緑化された状態を示している。 In FIG. 1, the planting material for slope 13 is fixed on the surface of the slope 12, and after a certain period of time, the seeds in the planting material for slope 13 germinate, the plant 16 grows, and the plant is greened. It shows the state that was done.
次に、本発明の法面用緑化資材１３を法面１２に付着させる方法を、図２のフローチャートを用いて説明する。 Next, a method of attaching the planting material 13 for slope according to the present invention to the slope 12 will be described with reference to the flowchart of FIG.
先ず、肥料溶解工程１０１では、法面用緑化資材１３に対して重量でその２〜４倍の水に、２０〜７０重量部となる肥料を投入し、撹拌の上、２４〜４８時間放置して、肥料を溶解する。 First, in the fertilizer dissolution step 101, 20 to 70 parts by weight of fertilizer is added to water 2 to 4 times the weight of the slope planting material 13, and the mixture is left for 24 to 48 hours after stirring. And dissolve the fertilizer.
次に、水溶性紙溶解工程１０２では、法面用緑化資材１３に対して重量でその２〜４倍の水に、トイレットペーパを法面用緑化資材１３の５〜２０重量部となるように、手で千切って投入し、撹拌して、トイレットペーパを繊維状に溶解する。 Next, in the water-soluble paper dissolving step 102, the toilet paper is 5 to 20 parts by weight of the slope greening material 13 in the water 2 to 4 times the weight of the slope greening material 13 by weight. Chop by hand, stir to dissolve the toilet paper into a fiber.
種子混合工程１０３では、先ず、肥料溶解工程１０１で肥料を溶解した溶液に水溶性紙溶解工程１０２でトイレットペーパ材が溶解し繊維状となって懸濁する溶液を加える。更に、法面用緑化資材１３の２０〜７０重量部となる種子を、その溶液に投入し、十分に撹拌して繊維状となったトイレットペーパ材と種子を懸濁させながら法面用緑化資材１３に対して重量でその１〜３倍の水を加え、スラリー濃度を調整して、法面用緑化資材スラリーとする。なお、種子、肥料及びファイバー材の配合比率並びに水の量は、法面の植物植生土壌の有無、勾配の程度によって、適宜変更することが望ましい。 In the seed mixing step 103, first, a solution in which the toilet paper material is dissolved and suspended in a fiber form in the water-soluble paper dissolving step 102 is added to the solution in which the fertilizer is dissolved in the fertilizer dissolving step 101. Furthermore, 20 to 70 parts by weight of seeds for the planting material for slope 13 are put into the solution, and the toilet paper material and the seeds which are made into a fibrous form by sufficient stirring are suspended and the planting material for slopes is suspended. 1 to 3 times the weight of water is added to 13 to adjust the slurry concentration to obtain a slope replanting material slurry. It should be noted that the mixing ratio of seeds, fertilizers and fiber materials and the amount of water are preferably changed as appropriate depending on the presence or absence of sloped plant vegetation soil.
吹付け機準備工程１０４では、コンプレッサと緑化資材吹付タンク（以下、単に「タンク」ともいう。）の入気側をエアーホースで接続し、排気側に吹き付けホースを接続する。 In the sprayer preparation step 104, the inlet side of the compressor and the greening material spray tank (hereinafter also simply referred to as “tank”) is connected with an air hose, and the spray hose is connected to the exhaust side.
次に、緑化資材吹付用タンク充填工程１０５では、緑化資材吹付用タンクに、法面用緑化資材スラリーを充填する。タンクの下部から、圧縮空気をタンク内に供給してバブリングさせると、タンク内の法面用緑化資材スラリーが撹拌され、懸濁状態が維持され好ましい。 Next, in the greening material spraying tank filling step 105, the greening material spraying tank is filled with the slope greening material slurry. When compressed air is supplied into the tank from the lower part of the tank to cause bubbling, the slope greening material slurry in the tank is stirred and maintained in a suspended state.
そして、緑化資材吹付工程１０６では、コンプレッサから圧縮された圧縮空気を緑化資材吹付用タンクに送り込み、吹き付けホースの先端から、法面用緑化資材スラリーを噴出させ、法面１２に吹き付け、法面用緑化資材１３を法面１２に付着させる。このとき、法面１２に窪み１４や亀裂１５が有る場合には、この窪み１４や亀裂１５に法面用緑化資材１３が吹き込むようにすると、法面１２における法面用緑化資材１３の定着が良好となり、好ましい。 Then, in the greening material spraying step 106, the compressed air compressed from the compressor is sent to the greening material spraying tank, and the greening material slurry for the slope is blown from the tip of the spraying hose and sprayed on the slope 12 for the slope. The greening material 13 is attached to the slope 12.

First, 27 parts by weight of the fertilizer was put into twice as much water as the slope planting material 13, and after stirring, left for 24 hours to confirm that the fertilizer was dissolved. In addition, toilet paper is poured into water twice as much as the slope greening material 13 by hand so that it becomes 3 parts by weight of the slope greening material 13 as a fiber material. The solution that was dissolved to become a fiber was added to the solution in which the fertilizer was dissolved, and the mixture was sufficiently stirred and suspended. Further, 38 parts by weight of seeds for the slope planting material 13 is poured into a solution in which the toilet paper material is dissolved and suspended in a fiber form, and is sufficiently stirred against the planting material 13 for the slope.

結果を下記表１にまとめる。実施例１〜５のいずれの場合も、法面用緑化資材１３は、法面１２が植物生育土壌の殆どない岩盤であるにもかかわらず、吹き付け後の法面１２への付着強度が強く、保水性に富む緑化資材１３の層が形成されていた。半年間の法面１２の緑化資材１３の層の状況を調べた結果、種子類の発芽や生育が良好で、植生が降雨や風等により流失や飛散することがないことが確認された。また、下記に説明する植生マット張工法を使用した比較例と比較しても、種子類の発芽状況や生育状況、及び法面用緑化資材１３の法面１２への付着強度においても遜色なく、実用性に優れていることが確認された。 The results are summarized in Table 1 below. In any case of Examples 1 to 5, the slope greening material 13 has strong adhesion strength to the slope 12 after spraying, even though the slope 12 is a bedrock with almost no plant-grown soil. A layer of the greening material 13 rich in water retention was formed. As a result of examining the condition of the layer of the greening material 13 on the slope 12 for half a year, it was confirmed that the seeds germinate and grow well, and the vegetation is not washed away or scattered by rain or wind. In addition, even in comparison with the comparative example using the vegetation mat tension method described below, the germination status and growth status of seeds, and the adhesion strength to the slope 12 of the planting material 13 for slope, It was confirmed that it was excellent in practical use.
以下、比較例について説明する。 Hereinafter, a comparative example will be described.
比較例１

Comparative Example 1
A vegetation in which a mat having a thickness of 5 to 10 mm composed of 4 parts by weight of seeds, 26 parts by weight of fertilizer, 34 parts by weight of soil improvement material, and 36 parts by weight of straw is disposed on the slope 12 and fixed to the slope 12 using anchor pins. The mat tension method was used as a comparative example. As a result of examining the condition of the greening slope 11 after 6 months of construction, it was confirmed that the seeds germinate and grow well, and the vegetation is not washed away or scattered by rain or wind.
比較例２
法面緑化資材１３の３５重量部となる肥料を法面用緑化資材１３の２倍の水に投入し、撹拌の後、２４時間放置し、肥料が溶解したことを確認した。また、ファイバー材として、水溶性紙ではないが入手が容易な新聞紙の古紙を法面用緑化資材１３の５重量部となるように、手で千切って法面用緑化資材１３の２倍の水に投入し、２４時間水浸させた後、手で撹拌した。次に、肥料が溶解した溶液に古紙を投入した水を投入し、十分に撹拌の上、法面用緑化資材１３の６０重量部となる種子を溶液に投入し、更に、十分に撹拌してスラリー化した。その後、実施例１と同様に吹付け機を用いて吹付作業を試みた。
Comparative Example 2
The fertilizer used as 35 parts by weight of the slope revegetation material 13 was put in twice as much water as the slope revegetation material 13 and allowed to stand for 24 hours after stirring to confirm that the fertilizer was dissolved. In addition, as a fiber material, waste paper that is not water-soluble paper but is easy to obtain is shredded by hand so that it becomes 5 parts by weight of the planting material 13 for slopes, twice the planting material 13 for slopes. The mixture was poured into water, immersed in water for 24 hours, and then stirred by hand. Next, water containing waste paper is added to the solution in which the fertilizer is dissolved, and after sufficiently stirring, 60 parts by weight of the seedling for greening material for slope 13 is added to the solution, and further stirred sufficiently. Slurried. Then, spraying work was tried using the spraying machine like Example 1.
結果を下記表１にまとめる。比較例２は、古紙は十分に繊維がほぐれず、古紙の状態でスラリー中に残ってしまい、吹付けホース内に古紙が閉塞し、安定した吹付作業を行うことが困難であった。よって、水溶性紙ではない新聞紙などの古紙は、ファイバー材に適していないことが確認された。 The results are summarized in Table 1 below. In Comparative Example 2, the waste paper was not sufficiently loosened and remained in the slurry in the waste paper state, and the waste paper was blocked in the spray hose, making it difficult to perform a stable spraying operation. Therefore, it was confirmed that waste paper such as newspaper that is not water-soluble paper is not suitable for the fiber material.
