Description
Technical field
The utility model relates to a kind of drainage system of retaining wall and its construction method, more particularly, to being filled out after retaining walls
Soil is the drainage system of clay.
Background technique
Retaining wall is widely used in one of civil construction project structures, due to retaining wall inevitably by
The effect of underground water in rolling earth behind retaining wall, this not only adds the increasings of the horizontal loading of retaining wall, and backfill water content to make
Retaining wall shearing strength reduces, and soil pressure increases after wall.To prevent ponding after wall from forming hydrostatic pressure, draining should be arranged in retaining wall
Measure.What retaining wall draining generallyd use is inorganization draining, i.e. setting drainpipe and drain hole spaced apart on the wall,
Moisture is discharged via at drainpipe to drain hole along metope.Following problems can be generated using the draining of this inorganization:
In use, constructing due to lack of standardization, material selection is unreasonable etc., draining blockage is easily caused, into
And cause impeded drainage.
In cold district, for retaining wall metope because moisture is in the presence of that can generate freeze thawing phenomenon, long term will be to retaining wall structure
Generate serious damage.
Traditional retaining wall rolling earth behind retaining wall drainage system is inconvenient to construct, and causes part retaining wall drainage system not set,
Directly affect the stabilization of retaining wall structure.
Utility model content
The utility model can prevent wall from carrying on the back ponding according to the above deficiency, provide a kind of drainage system of retaining wall, protect
It demonstrate,proves wall back soil stabilization, extend retaining wall service life.
The purpose of this utility model, which is that, provides a kind of retaining wall drainage system and its construction method, solves retaining wall
Water drainage behind the wall system is inconvenient to the problem of constructing.Alleviate it is not smooth from the farther away area sewerage of retaining wall, not in time the case where.
Have the characteristics that construction is simple is easy, ensure that the unobstructed of retaining wall drainage system, maintains the stabilization of the soil body after wall and wall.
The technical solution of the utility model is:
A kind of drainage system of retaining wall, including, retaining wall is the stickiness soil body after the wall of retaining wall, characterized in that keeping off
Cavity is offered after cob wall wall, the bottom casting concrete base of cavity fills out permeable or weak permeable above concrete base layer
Property filler, the stickiness soil body on rear side of permeable or weak water penetration filler since bottom every 1 ~ 1.5 meter of laying, one layer of gravel soil, often
The upper and lower level of layer gravel soil is laid with dense mesh type strainer, and retaining wall is provided with multilayer, and every layer is provided with outer low and inner high drainpipe, row
The inner end of water pipe is connected to collector pipe, which is located in permeable or weak water penetration filler.
After gravel soil, major part flows to permeable moisture in the utility model stickiness soil body along gravel soil lateral flow
Or weak water penetration filler, it is discharged through drainpipe, small a part of water can leak down through the stickiness soil body, leak into next layer of gravel
Soil, then permeable or weak water penetration filler is flowed to through gravel soil lateral flow, it is discharged through drainpipe, gravel soil provides an infiltration
Channel.
It should be noted that gravel soil loss can be effectively prevented in the setting of dense mesh type strainer.
Preferably, at least two layers of the gravel soil.
Preferably, the gradient of the drainpipe is the 4% ~ 6% of the gradient.
Preferably, the dense mesh type strainer is provided with 2 ~ 3 layers.
Preferably, the drainpipe is pvc pipe.
The effective dense mesh type strainer that catchments wraps up 3 ~ 5 layers, is spaced circumferential fixed.The setting of collector pipe can prevent permeable
Or the loss of weak water penetration filler, and can ensure that water flow is unimpeded.
A kind of construction method of the drainage system of retaining wall, as follows:
S1 first pours the first layer of retaining wall, and the top surface of first layer is above the ground level；
S2 offers cavity after retaining walls, is poured concrete base layer in subaerial position；
Drainpipe and collector pipe is arranged in S3 on the first layer of retaining wall；
S4 pours the preceding half storey in the second layer of retaining wall；
S5 inserts permeable or weak water penetration filler in the cavity；
S6 cuts out the stickiness soil body after retaining walls and reserves the 0.5-0.75 meters of height that are above the ground level, be laid with dense mesh type strainer,
Gravel soil and dense mesh type strainer；
S7 is poured retaining wall after the rear half storey in the second layer, and drainpipe and collector pipe are arranged on the second layer；
S8 repeats step S5；
S9 backfills 1 ~ 1.5 meter of the stickiness soil body of height, is laid with dense mesh type strainer, gravel soil and dense mesh type strainer；
S10 is poured third layer retaining wall, is laid with drainpipe and collector pipe；
S11 repeats step S8, S9, and so on；
The retaining wall of S12 the last layer, permeable or weak water penetration filler and the stickiness soil body are contour.
One layer height of the retaining wall is identical as a layer height of the stickiness soil body, is 1 ~ 1.5 meter.
The utility model has the advantages that
1. of simple structure and low cost, construction is easily achieved, it can prevent wall caused by due to sluicing hole plug fails from carrying on the back
Ponding guarantees that wall carries on the back soil stabilization.
2. avoiding retaining wall metope caused by inorganization draining from washing away, pollute and freeze thawing, extend retaining wall service life.
3. effectively mediating the underground water after wall in the soil body, the stabilization of the soil body after wall and wall is maintained.
The utility model has structure beneficial effect that is simple, at low cost, easy for construction, extending retaining wall service life.
