Description

A kind of concrete drainage pavement and construction, method for repairing and mending

Technical field

The present invention relates to road building technology field, particularly to a kind of concrete drainage pavement and construction, method for repairing and mending.

Background technology

Traditional concrete road surface, it is all that (reinforcement placing skeleton) pours into a mould concrete road surface at the scene, then on-the-spot large-area maintenance is carried out, rear maintenance of having constructed reaches concrete design strength and could use, construction period length and expend substantial amounts of resource, the climatic effect by winter, rainy season is big.Also must designing horizontal wall inscription in horizontal section and usual friendship mouth etc. so that draining, roadside must supporting gully or gutter.It addition, concrete road surface has occurred the defects such as crack, faulting of slab ends, purt mud, plat-bottom escape, it is difficult to after breakage repair, generally requires and break road surface in damage zone, remove old concrete, again build road surface by regulation operation.Therefore exploitation quickly, material-saving, environmental protection, convenient for maintaining road construction method have very important significance.

Summary of the invention

One of the technical problem to be solved is to provide a kind of concrete drainage pavement, and it is spliced laying by concrete prefabricated plate and forms, convenient construction and maintenance;In horizontal section peace with one voice without designing horizontal wall inscription, road surface gets final product draining without rainwater well head, improve road-ability and safety.

The two of the technical problem to be solved be to provide a kind of concrete road surface quickly, the construction method of environmental protection, accelerate concrete pavement construction speed, reduce the concrete road surface climatic effect by winter, rainy season;Meanwhile, adopt prestressed method according to the principle that concrete road surface is controlled by flexural tensile strength, save the natural resourcess such as cement, water, sand, stone.

Required for the present invention to solve the technical problem that three be to provide a kind of method facilitating concrete road surface rapid-maintenance, the problem being difficult to after solving concrete road surface breakage repair, can quickly resume traffic.

For solving one of above-mentioned technical problem, the technical scheme is that a kind of concrete drainage pavement, including concrete prefabricated plate, dowel steel, sleeper beam, rhone, it is spliced laying by some concrete prefabricated plates and forms, adjacent concrete prefabricated plate connects fixing by dowel steel, ground sleeper beam is located at the bottom surface of adjacent two block concrete prefabricated chunk stitching portions, and rhone is arranged at the road surface bottom surface being spliced by concrete prefabricated plate at interval;

Described concrete prefabricated plate is rectangular panel blocks, and its upper surface is provided with some vertical osculums, and surrounding end face is provided with some dowel steel connecting holes, dowel steel resigning hole, and both sides end face is provided with some longitudinal reserving hole channels, and reserving hole channel is through to both sides end face;Vertically extending to the longitudinal reserving hole channel of osculum, connects with longitudinal reserving hole channel;Some compressor wires it are additionally provided with inside concrete prefabricated plate.

Described dowel steel includes connecting rod, bolt, nut, and connecting rod includes horizontal cross bar and vertical circular arc wall, and bolt is provided with the bolt sleeve of annular, and nut is provided with the nut sleeve of annular;After bolt attaching nut, bolt sleeve forms a sealed inner chamber with nut sleeve Guan Bi, vertical circular arc wall in described connecting rod is placed in sealed interior intracavity, and each sealed inner chamber is placed into the vertical circular arc wall of two connecting rods respectively, and the horizontal cross bar of connecting rod connects dowel steel connecting hole.

For solving the two of above-mentioned technical problem, the technical scheme is that and concrete road surface is numbered piecemeal, adopt prefabrication and lifting construction, insert compressor wire in the prefabricated middle employing pre-tensioning system of concrete prefabricated plate.Concrete method step is:

A. first, road surface is carried out piecemeal numbering by the material property according to the designing requirement on road surface and compressor wire, concrete prefabricated plate;

B. stretch-draw prestressing force steel wire, according to piecemeal numbering precast concrete prefabricated chunk, the accurately position of reserved longitudinal dowel steel connecting hole;

C. embedding ground sleeper beam in the earth roadbed or blotter filled, accurately controls the end face absolute altitude of ground sleeper beam smooth with filling roadbed;

D. lift the first block concrete prefabricated chunk, make concrete prefabricated plate two ends just be held on horizontal ground sleeper beam;

E. the connecting rod of the dowel steel through antirust treatment is inserted in dowel steel connecting hole, lift by crane the second block concrete prefabricated chunk longitudinally to advance to the first block concrete prefabricated chunk, the other end making dowel steel inserts in the dowel steel connecting hole of the second block concrete prefabricated chunk, by the dowel steel of bolt, the sealed adjacent concrete prefabricated chunk of nut, connect fixing adjacent concrete prefabricated plate.

F. rhone is arranged at the road surface bottom surface being spliced by concrete prefabricated plate at interval, and is in the splicing seams place of adjacent two block concrete prefabricated chunks, and the drainage channel of rhone " U " type accepts the hydrops discharged from longitudinal reserving hole channel;
