Description
Technical field
The present invention relates to a kind of construction method of retaining wall drainage system.
Background technology
Retaining wall can support Roadbed Soil or the hillside soil body, prevent from banketing or soil deformation unstability, is current most widely used support structure thing in the engineering such as highway, railway.Retaining wall structure is various informative, but " supporting+draining " is its main constitute and function.In use, the damage of drainage system is a common frequently-occurring disease, owing to designing unreasonable, lack of standardization, the reason such as material selection is improper of constructing, causes loaded filter to deposit to lose efficacy, gutter blocking, retaining wall forms water pocket or wall seam seepage behind, finally affects the stable of retaining wall structure.
Traditional loaded filter, seepage water is easy perpendicular flow in sandy gravel stratum, and the bottom in a large number to retaining wall is concentrated, top gutter loses the effect of draining, and seepage water collects to gutter point, and current are large, easily take away fine sand, erosion loaded filter, alluvial gutter end.
Summary of the invention
Its object of the present invention is just the construction method providing a kind of retaining wall drainage system, solves the problem that retaining wall gutter easily blocks inefficacy.Alleviate water percolating capacity larger time bottom gutter charge for remittance concentrate, draining not in time, the situation of the anhydrous row of top gutter, prevention ponding soaks foundation.Have the advantages that construction is simple, ensure that the unobstructed of retaining wall drainage system, after maintaining body of wall and wall, the soil body stablizes.
Realize above-mentioned purpose and the technical scheme taked, comprise retaining wall and loaded filter, gutter is provided with in retaining wall, described retaining wall is provided with at least two layers, non-woven fabrics water barrier and header is provided with bottom retaining wall, header is close to the retaining wall back of the body and is longitudinally laid, and the bottom of header is inserted in gutter, between adjacent two gutters, arrange herringbone longitudinal gradient.
Described construction method step is as follows:
I, the concrete base layer of loaded filter is built;
II, construction one section of retaining wall, pre-buried gutter;
III, fill sandy gravel stratum, lay non-woven fabrics water barrier, header is installed;
IV, the more than repeating the IIth, III step, until to wall top;
V, build top platform or top backfill clay, block the surface water.
Compared with prior art the present invention has the following advantages.
1, the difficult problem that retaining wall gutter easily blocks inefficacy is solved;
2, alleviate water percolating capacity larger time bottom gutter charge for remittance concentrate, draining not in time, the situation of the anhydrous row of top gutter, prevention ponding soaks foundation;
3, construct simple.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation front view of the present invention.
Fig. 2 is structural representation lateral view of the present invention.
Detailed description of the invention
The construction method of native system comprises retaining wall 1 and loaded filter 6, gutter is provided with in retaining wall 1, as shown in Figure 1, 2, described retaining wall 1 is provided with at least two layers, non-woven fabrics water barrier 5 and header 3 is provided with bottom retaining wall 1, header 3 is close to the retaining wall back of the body and is longitudinally laid, and the bottom of header 3 is inserted in gutter 4, between adjacent two gutters, arrange herringbone longitudinal gradient.
Described header 3 dense mesh type filter screen parcel 2 ~ 4 layers, interval 20cm hoop is fixed; Described gutter 4 caliber is greater than header caliber.
Described non-woven fabrics water barrier 5 stretches in loaded filter 6, and stretch into that the degree of depth is loaded filter 6 width 2/3.
Described retaining wall 1 top-rear side is concrete platform 2, is provided with Concrete Anti water layer 7 bottom loaded filter 6.
Described construction method step is as follows:
I, the concrete base layer of loaded filter is built;
II, construction one section of retaining wall, pre-buried gutter;
III, fill sandy gravel stratum, lay non-woven fabrics water barrier, header is installed;
IV, the more than repeating the IIth, III step, until to wall top;
V, build top platform or top backfill clay, block the surface water.
The drainage system of the present invention to loaded filter and gutter composition improves, and adopts the form of layering draining, reduces the flowing of underground water in loaded filter, arrange header, prevent gutter to block.The present invention is simple to operate, utilizes existing versatile material, improves, have very high practicality and using value to structure and construction method.
The present invention is provided with header, and along retaining wall, longitudinally arranging perforated plastic oozes (thoroughly) water pipe, is convenient to collect seepage water, improves water flow path.Header is provided with longitudinal gradient, can enter the silt of pipeline by Automatic clearance.Current flow rapidly into gutter from header, are conducive to silt to go out pipeline.
Take layering discharging mode, in loaded filter, be provided with waterproof non-woven fabrics water barrier, enhance the ability that header collects seepage water, slow down seepage water to the flowing bottom loaded filter, each layer collection gutter all can be played a role preferably.
The present invention includes
The selection of 1 material
Water proof material: waterproof geotextiles.
Filter screen: 400 order polyethylene filter screens.
Filtrate: prototype gradation gravel.
Header: perforated plastic oozes (thoroughly) water pipe.
Gutter: plastic pipe.Caliber is greater than header.
Concrete: C20, builds bottom loaded filter.
2 loaded filters fill
The thickness of loaded filter is relevant with execution conditions, and execution conditions better, single filled height is less than 1.0m, and loaded filter 30cm is thick to be advisable; The execution conditions of loaded filter are poor, and single filled height is greater than 1.0m, should increase the thickness of loaded filter, conveniently fills.
Graded gravel successively fills closely knit, when should not maybe tamping, answers layering to water closely knit.
3 collection gutters are installed
Header dense mesh type filter screen parcel 2 ~ 4 layers, interval 20cm hoop is fixed.Header is close to the wall back of the body and is longitudinally laid, between adjacent two gutters, arrange herringbone longitudinal gradient, lays fluid-tight geotextiles together in the sandy gravel stratum at the bottom of header.The bottom of header is inserted in gutter through walls.Drainpipe pre-buried, in retaining wall, arranges flowing water slope outside wall.Gutter is arranged on the lowest part that charge for remittance is concentrated, and for accelerating drainage effect, gutter extends 20cm and imbeds in sandy gravel stratum, and perforate, with dense mesh type filter screen parcel 2 ~ 4 layers (containing termination).
4 retaining wall constructions
Retaining wall or to build by laying bricks or stones or cast-in-place, needs firm closely knit, water-tight.Time cast-in-place, completed loaded filter lays barrier material, prevent cement paste from flowing into sandy gravel stratum, shutoff gravel space.
5 effect detection
1, filtrate and gutter up-to-standard, job specfication, filtrate fills closely knit, and gutter is laid by figure, and parcel is appropriate.
2, retaining wall body of wall is firm, protects completed drainage ditch in wall construction.
3, construct before wall roof panel, loaded filter is poured water inspection drainage effect.
