Description
Technical field
The present invention relates to the Building technology of dykes and dams (cofferdam, roadbed, shelves cob wall).Be a kind of biomimetic features and method of novel soft foundation fill.The method that a kind of batch production is produced the dykes and dams member and carried out quick fill.
Background technology
This is right and proper for thousands of years theory for " confront soldiers with generals and stem water with earth ".This seems simple dam configuration is not that nothing can be studied, since arrogant Yu harnesses the river, and the historical summary that can examine, the dykes and dams technology is to threaten the people's lives peacefulness always, is perplexing the great research topic of socio-economic development.Along with the development of environmental science, geological sciences, computer technology, two phase flow and Fei Niu stream technology, people have the development of advancing by leaps and bounds to the dykes and dams Study on Technology.To the research of dykes and dams stress stability, the research of failure mechanism, the research of structural meterials, the research and the relevant problem of soft foundation, a large amount of reports and patent are arranged all both at home and abroad.But prior art does not all relate to the biomimetic features and the method for fill, the research of light material bed course, do not solve the differential settlement slippage problem that produces because of the weight of dam body is unbalanced yet, more do not relate to the fill method rapidly and efficiently of the prefabricated dykes and dams member of batch production.King crab formula lightweight dam configuration of the present invention and method not only have tough and tensile shell mechanism, and balanced an amount of weight makes dykes and dams that globality be arranged, and have in just gentlely, temper toughness with gentleness, and what can adapt to ground heavyly moves variation.And cost is low, the duration short, it is wide to be suitable for.By retrieving domestic and international patent documentation and 25 relevant databases, from the data that searches out, do not found to have identical research.
Owing to be covered with marine sediment layer since the deep Quaternary Period on the coastal beach, it is characterized in that: the water content height, void ratio is big, and transmission coefficient is little, buries deeply, and bearing capacity and shear strength are low, and be highly sensitive, and consolidation time is grown or the like.It is typical soft foundation.So exist following problem in design and fill: (1) soft foundation: general processing method is to avoid soft foundation or excavate soft layer, but buries deep a lot of engineerings for soft base, and this way does not gear to actual circumstances.Can only fill on soft base.(2) levee body is overweight: for soft base, gravity dam is not good more heavily more, on the one hand, the overweight excess hydrostatic pressure that causes in the dam soil increases, and effective stress reduces, and shear strength reduces, under Wave Load, the bottom principal direction of stress is not stopped paying out to give birth to and is changed, and causes ground to destroy; On the other hand, dam body is overweight will easily cause unrestrained more at design link restriction levee crown height, unrestrained more current scour dykes and dams are washed into zanjon earlier behind wave wall, the wave wall depression is toppled over, form the casual top overflow of seawater and wash away earth embankment, make the slump layer by layer of piece stone revetment until scabbling levee body.(3) the loose barrier properties of dykes and dams material is poor: filling the dykes and dams that cause with mud and stone, concerning ten borough chief's dikes, all is discrete material, and ground has change slightly, and the slit is just arranged, and water will leak out.The levee body seepage is a big hidden danger, and placed rockfill erosion control masonry quality is poor, and loosening easily distortion causes water to infiltrate and washes in a pan erosion levee body earth material.(4) poor stability: often occur differential settlement, landslide, displacement in the construction period or after building up, suffer heavy losses once chance earthquake, typhoon, dyke is ruined, inwelling.(5) fixed slowly long in time limit: the transmission coefficient of bury is 10
6-10
8Levee body earthwork heap does not get on, and can't stand, and the engineering time is long, although adopted measures such as plastic draining board, geotextiles and sand cushion, and still will be according to the strict control of bearing capacity of foundation soil rate of loading.In case slippage occurs, just need to stay and could continue construction in a year or so, can't the mechanization rapid construction.(6) side's amount is big: the used material of dykes and dams generally all is a large amount of earth and stone material, because levee body earthwork heap does not get on, can't stand, the depositional gradient of the levee body earthwork reaches 1: 16 than greatly during construction, and suffer the erosion of wind, wave, ice, and make idle side's amount quite big, expense is very high.Or the like.
Summary of the invention
King crab also claims the east king crab, formal name used at school Tachypleus Tridentatus, and arthropod, the crust of cephalothorax is half-moon-shaped, and the crust of belly is hexagon, and six pairs of appendages are arranged, six pairs of sheet nectopods.Be distributed in the Pacific Ocean, common in the tidal-flat area, two of male and female always together.Its hard shell, the structure of arch form, the complete bodily form, if the volt on beach, even big again stormy waves tide is not moved it yet, again Xiong Meng shark all how not it.And dykes and dams are just needing structure like this and characteristic.
The Building technology of dykes and dams (cofferdam, roadbed, shelves cob wall) comprises that ground processing, dam embankment, stability analysis, wave resistance energy dissipating, antiseepage hold one's breath, heavyly move observation etc.The present invention is directed to the problem that dyke exists, at traditional in the past dykes and dams in theory, propose a new fill structure and a method---the structure and the method for king crab formula lightweight dykes and dams.Its essential characteristic is: dykes and dams are seen as a king crab formula biosystem, the architectural characteristic design construction dykes and dams of imitative king crab.Promptly make the shell of dykes and dams, or the shell of dykes and dams part,, insert other packing material then, make it to produce loss of weight, reinforcement, antiseepage, isolation, effect that heap is high, improve dykes and dams intensity with the yielding position of iliacus materials for support dykes and dams with high-strength material.In soft foundation, adopt the lightweight bed course to be located at the position of easy depression slippage, thereby alleviate the weight at the easy depression of dykes and dams position, adjust the dykes and dams balance, with balanced dykes and dams loading, strengthen resistance to overturning.On gravel foundation, plug continuous barrier sheet, to overcome seepage.Whole dykes and dams join together, support each other, rely on each other, check and balance, and support mutually.And insert ground deeply with a plurality of bases of dam, it is gentle that dykes and dams are had just, temper toughness with gentleness, and molten with ground be one, with the elimination differential settlement, guarantee the safety of dykes and dams.
Its fundamental technics method comprises: lightweight dam body, hard structure dam shell, isolate antiseepage, deeply insert base of dam, be linked to be integral body.
1. lightweight dam body: for soft foundation, although adopted measures such as plastic draining board, geotextiles and sand cushion, ground is not iron-plated.Because the lack of uniformity of dyke (dam), must make loading inconsistent of ground under the dykes and dams, and produce differential settlement.The lightweight dam body is set just can effectively be addressed this problem.Promptly the intensity according to ground adopts light material or hollow structure material as dam body, and the outside covers earth, stone and turf etc.Lightweight dike core method is arranged, and promptly whole dam core adopts light material or hollow structural members to build, and alleviates dykes and dams weight, strengthens the dykes and dams bulk strength.Local completion method is promptly buried light material at a certain position of dykes and dams underground as the position of the easiest depression, to adjust the dykes and dams balance.Dam foot mat method is promptly spread the light material that one deck has certain intensity at the bottom of dykes and dams pad, to enlarge the scope of foundation load power diffusion, simultaneously the soft soil that crouches is down had restrictive function.Mix method, promptly mix lightweight filler in the dyke (dam) earthwork or concrete, make cubic metre of earth dehydration fast, unit weight reduces, and intensity increases, and it is stable to stand, and the slope is than improving.
2. hard structure dam shell: because stormy waves is major reasons that dykes and dams destroy to the erosion of dykes and dams, so the high strength hard dam shell is very necessary.Make the shell of dykes and dams with high-strength material, or the shell of dykes and dams part, and support in it, form the structure of stablizing three firm light, insert discrete material then with rib and lacing wire form.
3. isolation antiseepage: when building dykes and dams on the bigger ground of transmission coefficient, ground and levee body seepage are a big hidden danger.Traditional dykes and dams ground has change slightly, and dam body just has the slit, and water will leak out, and the loosening easily distortion of placed rockfill erosion control masonry causes water to infiltrate and washes in a pan erosion levee body earth material.So isolating antiseepage can not be ambiguous.Especially on gravel foundation, need to plug continuous barrier sheet.Barrier sheet adopts the I type plate member or the M type plate member of king crab formula lightweight dykes and dams.Plugging the degree of depth decides on the transmission coefficient of ground.
4. insert base of dam deeply: because the rheological characteristic of foundation soil in the depression problem that solves dykes and dams, can not be ignored the displacement problem of dykes and dams.Promptly in the structure of dykes and dams, have a plurality of bases of dam that are connected with dam body to insert soft base, reduce slippage, and molten with ground be one.
5. be linked to be integral body: for conventional dam, constituting the big again block of dam body, still is discrete material also, is necessary they are joined together.No matter be barrier sheet, or the hard dam shell, or lightweight bed course hollow structure material, adopt methods such as securing member, tongue and groove, male and female seam, overlapping, buckle or welding, whole dykes and dams member is joined together.Support each other, rely on each other, check and balance, support mutually.
