Description
【０００１】[0001]
本考案は、主として、二次覆工を施さないトンネルの一次覆工の表面に貼着す るトンネル用防炎防水シ−トに関するものである。 The present invention mainly relates to a flameproof and waterproof sheet for a tunnel, which is attached to the surface of a primary lining of a tunnel without a secondary lining.
【０００２】[0002]
一般に、トンネルは、地山をア−チ状に掘削してその上に一次覆工を施し、こ の一次覆工の上に防水シ−トを貼着してから二次覆工を施工して構築するのが通 常である。然し乍ら、上記トンネルの構築に際して、パイロットトンネルと呼ば れる一次覆工上に防水シ−トを貼着しただけの小型のトンネルを構築し、これを 作業坑として或いはこれを拡幅して本格的なトンネルを構築したり、更には、こ れを避難坑やメンテナンス用の坑とすることが行われている。 Generally, in a tunnel, the ground is excavated in the shape of an arch, the primary lining is applied on it, and the waterproof sheet is attached to the primary lining before the secondary lining is applied. It is normal to build it. However, when constructing the above-mentioned tunnel, we constructed a small tunnel, called a pilot tunnel, in which a waterproof sheet was simply attached to the primary lining, and used as a working pit or widening it to create a full-scale tunnel. Is being constructed, and this is also used as an evacuation pit or a maintenance pit.
【０００３】 而して、上記のパイロットトンネルに貼着される防水シ−トは防水性の面から 防水効果の高い合成樹脂製のものが用いられているため、炎により溶融したり、 炎上する恐れがあり、特に、炎上した場合、該パイロットトンネルを作業坑にし て構築したトンネルにあっては、損傷を受けて使用不能になることもある。従っ て、本来ならば、難燃性の防水シ−トが安価であればそれを用いればよいが、こ の難粘性の防水シ−トは高価に過ぎ、また、不燃性の防水シ−トは実現されてい ない。Since the waterproof sheet attached to the pilot tunnel is made of a synthetic resin having a high waterproof effect from the viewpoint of waterproofness, it is melted or burned by a flame. There is a possibility that the pilot tunnel may be damaged and rendered unusable, especially if it burns up. Therefore, if the flame-retardant waterproof sheet is originally cheap, it may be used, but this non-flammable waterproof sheet is too expensive, and the non-combustible waterproof sheet is also used. Has not been realized.
【０００４】[0004]
本考案は、上述のような従来技術に鑑み、炎を受けても溶融したり炎上したり する恐れがなく、パイロットトンネルの一次覆工の上に貼着するのに好適な安価 なトンネル用防炎防水シ−トを提供することを、その課題とするものである。 In view of the above-mentioned prior art, the present invention is an inexpensive tunnel protective material suitable for being attached onto the primary lining of a pilot tunnel without the risk of melting or burning even if it receives a flame. It is an object of the invention to provide a flameproof sheet.
【０００５】[0005]
上記課題を解決することを目的としてなされた本考案トンネル用防炎防水シ− トの構成は、トンネルの一次覆工の表面に貼着するシ−トであって、合成樹脂製 の防水シ−トの片面に防火剤を塗布又は積層若しくは吹き付けて防火層を形成し たことを特徴とするものである。 The structure of the flameproof and waterproof sheet for tunnels of the present invention made to solve the above problems is a sheet to be attached to the surface of the primary lining of a tunnel, and is a synthetic resin waterproof sheet. A fireproof layer is formed by coating, laminating or spraying a fireproofing agent on one side of the container.
【０００６】 上記の防炎防水シ−トにおいて、防水シ−トは、その防火層形成面を、予め、 梨地やシボ面，起毛面に形成しておけば、防水シ−トに対する防火剤の付着力が 増大して、防火層が脱落するような恐れはおよそ皆無となる。 また、防水シ−トの他面に薄い不織布等から成る通水緩衝層を設け、地山から の出水を前記通水緩衝層を伝って流下させるようにしてもよい。In the above-mentioned flameproof and waterproof sheet, if the fireproof layer forming surface of the waterproof sheet is previously formed on a matte surface, a textured surface, or a raised surface, a fireproof agent for the waterproof sheet is obtained. There is almost no risk of the fire barrier falling off due to increased adhesion. Further, a water-permeable buffer layer made of a thin non-woven fabric or the like may be provided on the other surface of the waterproof sheet so that water from the natural ground flows down along the water-permeable buffer layer.

次に、本考案の実施の形態を図により説明する。図１は本考案防炎防水シ−ト の一例の断面図、図２は図１のシ−トを一次覆工の表面に貼着する状態の断面図 、図３は本考案防炎防水シ−トの別例の断面図であり、また、図４はパイロット トンネルの一次覆工表面に本考案防炎防水シ−トを貼着した貼着した状態の断面 図である。 Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a sectional view of an example of the flameproof and waterproof sheet of the present invention, FIG. 2 is a sectional view of the sheet of FIG. 1 attached to the surface of a primary lining, and FIG. 3 is a flameproof and waterproof sheet of the present invention. FIG. 4 is a sectional view of another example of the sheet, and FIG. 4 is a sectional view showing a state in which the flameproof and waterproof sheet of the present invention is attached to the primary lining surface of the pilot tunnel.
【０００８】 図１において、ＡはＥＶＡ樹脂等から成る防水シ−ト１の片面に、防火剤２を 塗布，ラミネ−ト，吹き付け等により積層，定着して防火層２を形成した本考案 トンネル用防炎シ−トである。この防炎シ−トＡは、図２に示すように、その他 面に予め取付けヒレ３を適宜間隔ごとに設けておき、地山に吹付けコンクリ−ト により形成した一次覆工Ｇに、取付けヒレ３を釘打ち４等により固定して一次覆 工Ｇの表面に貼着するのである。In FIG. 1, A is a tunnel according to the present invention in which a fireproof layer 2 is formed by laminating and fixing a fireproofing agent 2 on one side of a waterproof sheet 1 made of EVA resin or the like by laminating, laminating, spraying or the like. A flameproof sheet. As shown in FIG. 2, the flameproof sheet A is provided with mounting fins 3 on the other surface in advance at appropriate intervals, and is mounted on the primary lining G formed by spraying concrete on the ground. The fins 3 are fixed by nailing 4 or the like and attached to the surface of the primary lining G.
【０００９】 また、図３に示すものは、図１のトンネル用防炎シ−トＡの防火層２を形成し ない面に、不織布等を貼着して緩衝層又は通水緩衝層５を形成したトンネル用防 炎シ−トＡ’である。この防炎シ−トＡ’も上記と同様にして一次覆工Ｇの表面 に貼着する。In addition, as shown in FIG. 3, a non-woven fabric or the like is attached to the surface of the tunnel flameproof sheet A of FIG. 1 on which the fireproof layer 2 is not formed to form the buffer layer or the water-permeable buffer layer 5. It is the formed flameproof sheet A'for tunnel. This flameproof sheet A'is also attached to the surface of the primary lining G in the same manner as above.
【００１０】 上述のようにして本考案防炎防水シ−トＡ，Ａ’をパイロットトンネルのよう な二次覆工を施さない一次覆工Ｇのみのトンネルの表面に貼着すれば、火災等に あっても、火炎により防水シ−ト１が溶融したり炎上したりする恐れはなく、従 って、火炎等があっても、パイロットトンネルを足掛かりにして構築した通常の トンネルにその影響が及ぶ恐れはおよそ皆無である。勿論、本考案シ−トは防水 性を具えているので、一次覆工Ｇから出水しても漏水することはない。特に、図 ３のように、防水シ−ト１の防火層２を形成しない面に通水緩衝層５を設けてお けば、防水効果は一層顕著なものとなる。As described above, if the flameproof and waterproof sheets A and A'of the present invention are attached to the surface of the tunnel having only the primary lining G without the secondary lining such as the pilot tunnel, a fire or the like will occur. Even if there is, there is no risk that the waterproof sheet 1 will be melted or burned up by the flame. Therefore, even if there is a flame etc., it will not affect the normal tunnel constructed using the pilot tunnel as a foothold. There is almost no fear of reaching. Of course, since the seat of the present invention is waterproof, even if water comes out from the primary lining G, it will not leak. In particular, as shown in FIG. 3, if the water-permeable buffer layer 5 is provided on the surface of the waterproof sheet 1 where the fireproof layer 2 is not formed, the waterproof effect becomes more remarkable.
【００１１】 なお、図示はしないが、前述したように、防水シ−ト１の防水層２形成面を、 予め、梨地やシボ面，起毛面に形成しておけば、防水シ−ト１に対する防火剤の 付着力が増大して、防火層２が脱落するような恐れはおよそ皆無となる。Although not shown, as described above, if the surface of the waterproof sheet 1 on which the waterproof layer 2 is formed is formed in advance on a matte surface, a textured surface, or a raised surface, the waterproof sheet 1 will be removed. There is almost no risk that the fireproof layer 2 will fall off due to the increased adhesion of the fireproofing agent.
【００１２】[0012]
本考案は上述のとおりであって、合成樹脂製の防水シ−トの片面に防火剤を塗 布又は積層若しくは吹き付けて防火層を形成したから、これをトンネルの一次覆 工の表面に防火層を外側にして貼着すれば、二次覆工を施工しなくても、火炎に あった場合、炎は防水層により食い止められて、防水シ−トが炎により溶融した り、炎上したりする恐れはなく、従って、二次覆工を施工しないバイロットトン ネルの一次覆工上に貼着する防炎防水シ−トとして好適である。 The present invention is as described above, and since the fireproof layer is formed by coating or laminating or spraying the fireproof agent on one side of the waterproof sheet made of synthetic resin, the fireproof layer is formed on the surface of the primary lining of the tunnel. If it is attached with the outside as the outside, even if the secondary lining is not applied, when there is a flame, the flame is stopped by the waterproof layer and the waterproof sheet melts or burns up by the flame. There is no fear, and therefore, it is suitable as a flameproof and waterproof sheet that is attached to the primary lining of the bilot tunnel without the secondary lining.
