Description
Technical field
The utility model relates to a kind of earth and rockfill dam metal mesh opening case protective slope structure, relate to core wall rockfill dam, rock and earth dam, be suitable for being used on the protective slope structure of native core wall rockfill dam, asphaltic concrete core wall loose rock dam, geomembrane core wall rockfill dam, reinforced concrete face rockfill dam, bituminous concrete surface sheetpile masonry dam, geomembrane rock, homogeneous earth dam and subregion earth dam etc.
Background technology
Existing earth and rockfill dam bank protection adopts that boulder is piled up more, laid dry, grout, or adopts prefabricated, cast-in-situ concrete sash to add and rockfill, or turfing etc.The subject matter that exists has, to bank protection with the particle diameter and the systematicness of piece stone have relatively high expectations, anti-impact erosion or wash in a pan erosion or anti-seismic performance is relatively poor, construction inconvenience, cost of investment are high.
Along with going deep into of hydroelectric development and engineering construction, the earth and rockfill dam protective slope structure has been proposed high request, abundant or do not have big dam block stone area to solve the dam slope protection question at cobble, at casual top current or meet the heavy rain current and swim dam slope at present anti-impact erosion ability is arranged, prevent the naughty erosion of storehouse, upstream water or downstream tail water, chance has anti-seismic performance, convenient construction when shaking doughtily, reduced investment, or the like.For remedying the deficiencies in the prior art, satisfy hydroelectric project requirements at the higher level and demand, be badly in need of a kind of novel protective slope structure.
Summary of the invention
The purpose of this utility model provides a kind of earth and rockfill dam metal mesh opening case protective slope structure, and this structure is used on the earth and rockfill dam bank protection, have with the erosion of convenient, the anti-impact of material, anti-scour, anti-seismic performance strong, easy construction, the characteristics that cost is low.
A kind of earth and rockfill dam metal mesh opening case protective slope structure described in the utility model is achieved in that
A kind of earth and rockfill dam metal mesh opening case protective slope structure, it is made up of casing and building stones, and building stones are filled in the casing;
Wherein: casing is to be kinked by netting twine fixedly to constitute, the netting twine intersection kinks, add the support edge line at periphery and form the mesh strip that is used for tank floor, casing side and casing capping, mesh is arranged on the mesh strip, the mesh strip that is used for the casing side forms casing with the mesh strip that is used for tank floor admittedly by binding is stubborn, and the casing capping is connected with casing by binding;
The material of netting twine, support sideline, binding is the high-strength stainless metal wire rod, or the metal wire rod that carried out antirust processing, or is coated with the metal wire rod of rust-preventing film;
Body structure is four limit body structures, and height C is in 10cm～200cm scope, and length A is in 10cm～300cm scope, and width B is in 10cm～300cm scope, and building stones 2 particle diameters are in 5cm～100cm scope;
Height C is in 30cm～100cm scope preferably for casing, and length A is in 50cm～200cm scope preferably, and width B is in 30cm～100cm scope preferably, and the building stones particle diameter is in 10cm～80cm scope preferably;
Body structure is cube structure, rectangular structure, prismatoid structure, isosceles trapezoid body structure;
Body structure is tri-prismoid structure, hexagonal prism structure, eight prism structures, polygon prismoid structure;
Mesh is triangle, quadrangle, hexagon, ellipse;
Compile around fixing fastening line in the mesh centre.
Because a kind of earth and rockfill dam metal mesh opening case protective slope structure described in the utility model, adopted the frame mode of metal mesh opening box body and stone combined, this has just reduced the requirement to building stones particle diameter and systematicness, is lacking big dam block stone area, and available cobble or rubble substitute; Pack into a plurality of casings of can gathering materials on the spot form metal mesh opening case protective slope structures, easy construction, and no bulk stone exploitation and transporting, cost is cheaper;
Because the basic material of casing is the high tensile metal wire rod through antirust processing, or the metal wire rod that carried out antirust processing, or be coated with the metal wire rod of rust-preventing film, twist or twist into knot and the edged line forms mesh strip more through two, single, a plurality of mesh strips are assembled into the metal mesh opening case with antirust function and belong to flexible structure, can adapt to different construction environments and complex-terrain; Tensile strength is big, extension is stressed evenly, and strong shock resistance, partly carrying, global response; Non-corroding, good endurance; Good water permeability has fixed and the greening effect to domatic; Anti-current scour, erosion can effectively slow down water velocity, have the energy dissipating effect; Construction is convenient, saves cost, and need not consider to increase engineering cost because of place environment and other constructional materials of outsourcing;
Because casing capping and metal mesh opening box body can conveniently be opened, building stones separate assembling with casing and all make things convenient for, and flexible casing can tile and laminate transportation, and the convenient transport cost is low, the filling building stones of can also gathering materials on the spot at the dam scene further reduce and build the dam construction cost;
The building stones particle diameter that the utility model is selected is filled in the body structure of optimal design, can relax particle diameter and systematicness requirement to building stones, have prevent to overflow top or heavy rain current to the erosion of downstream dam slope, prevent storehouse, upstream water or downstream tail water to the naughty erosion of dam slope, prevent under the geological process that the slop protection block stone body is loosening and tumble, prevent that dam slope from producing the crack, adapting to advantages such as dam deformation ability, guarantee the advantage of dam and personnel's safety;
Because earth and rockfill dam metal mesh opening case protective slope structure described in the utility model, can be three limits, four limits, hexagon or octagon prism or polygon prismoid structure, the various combination of size and dimension, can satisfy different construction operating modes, according to different requirement of engineering, the bank protection of convenient customization corresponding construction shape;
Because the utility model has been selected the different high tensile metal wire rod of different mesh-structured shape and size, specification for use, has been cooperated different building stones structures, can be applicable to different dam engineering bank protections;
Owing to compile between mesh described in the utility model around fixing fastening line, particularly between hexagon or oval mesh, compile around fixing horizontal or vertical fastening line, the mesh non-deformability is provided, has reinforced the globality of net cage, strengthened the supporting capacity of whole hole case; Overall structure is more firm.
