Abstract
The utility model belongs to the field of municipal and highway construction facilities, and discloses an inverted filter device for water drainage of a retaining wall. The inverted filter device for the water drainage of the retaining wall is composed of a vertical water permeable plastic drainage plate row, horizontal water permeable plastic drainage plate rows and an inverted filter layer, wherein the vertical water permeable plastic drainage plate row and the horizontal water permeable plastic drainage plate rows are all formed by arranging porous plastic single plates in rows, and the horizontal water permeable plastic drainage plate rows are arranged at intervals in a parallel mode. Except for the bottom layer of the horizontal water permeable plastic drainage plate rows, the other layers of the horizontal water permeable plastic drainage plate rows are in lap joint with the vertical water permeable plastic drainage plate row through short connecting edges of the horizontal water permeable plastic drainage plate rows, the vertical water permeable plastic drainage plate row is arranged on the back of the retaining wall, the lower end of the vertical water permeable plastic drainage plate row and the corresponding end of the bottom layer of the horizontal water permeable plastic drainage plate rows are arranged in the inverted filter layer in an embedded mode, and the inverted filter layer is communicated to the outside of the retaining wall through a water drainage pipe. The inverted filter device for the water drainage of the retaining wall is suitable for clayey soil backfill retaining walls, the amount of used sand and gravel materials can be reduced, the inverted filter device for the water drainage of the retaining wall is convenient to construct and not prone to blockage, the water drainage effect of the clayey soil backfill retaining walls can be remarkably improved, and therefore the safety factor of the retaining wall can be effectively increased.
Description
Technical field
A kind of anti-filter device for the retaining wall draining of the utility model belongs to the highway construction facility field of having stable political situation, city.
Background technology
Be widely used at present retaining wall in numerous engineering constructions such as urban construction, highway construction, its purpose is the soil body or lithosome after the backfill of the wall back of the body are propped up gear.Usually mainly the soil body is played a gear effect, so be called retaining wall.The retaining wall soil body behind is loose, porous media, and under numerous hydraulic actions such as rainwater, flowing water, its active force to retaining wall can significantly increase.Therefore in DESIGN OF RETAINING WALLS and work progress, when be the cohesive soil backfill thereafter, loaded filter need to be set especially, its reason is that the cohesive soil transmission coefficient is very little, and draining, infiltration are extremely difficult, need the employing loaded filter assist draining.
The form that arranges of prior art loaded filter mainly adopts anti-filter bag and two kinds of forms of filter zone.Generally speaking retaining wall Q behind vertically full section filter zone D is set, as shown in Figure 3; When retaining wall is higher, but filter zone is arranged to anti-filter bag B form in the vertical direction spacing as greater than 3m the time, and as shown in Figure 4, cohesive soil N tamped backfill is all adopted at filter zone D and the following position of anti-filter bag B and peripheral position.
No matter adopt which kind of drainage mode, when wall is the water permeability such as backfill sandy soil preferably during material behind, drainage effect is remarkable, but when being thereafter the relatively poor material of the water permeabilitys such as viscous soil horizon, drainage effect is not remarkable, reason is that the viscous soil horizon seepage paths is longer, and water time of staying in soil is longer, and soil pressure effect meeting increases.Therefore, prior art retaining wall loaded filter arranges that form exists that drainage effect is poor, constructional difficulties, construction quality are difficult for guaranteeing, has retaining wall slippage, cracking, tilts even collapses security hidden trouble.
The utility model content
The purpose of this utility model provides a kind of anti-filter device for the retaining wall draining, to promote the drainage efficiency of viscous soil horizon in the retaining wall, strengthens the safety of retaining wall.
Specific embodiments of the present utility model is as follows:
A kind of anti-filter device for the retaining wall draining of the utility model, formed by vertical, horizontal water permeability plastic row plate and loaded filter, laterally water permeability plastic row plate parallel interval arranges, except bottom, all the other each layers laterally water permeability plastic row plate connect minor face and vertical water permeability plastic row plate overlap joint by it, vertical water permeability plastic row plate arranges according to the retaining wall back of the body, the lower end of vertical water permeability plastic row plate and horizontal water permeability plastic row plate bottom corresponding end, be inlaid in the loaded filter, loaded filter leads to outside the retaining wall by gutter.
Described vertical, horizontal water permeability plastic row plate is rearranged by the porous plastics veneer.
The link of described horizontal water permeability plastic row plate has vertical permeable connection minor face.
Described vertical water permeability plastic row plate and the vertical plane upper end angle that arranges according to the retaining wall back of the body is 0 degree ~ 15 degree.
The utility model retaining wall draining anti-filter device is applicable to cohesive soil backfill retaining wall, can save the sand material consumption, and easy construction is difficult for silting, significantly improves the drainage effect by cohesive soil backfill retaining wall, thus Effective Raise retaining wall safety factor.

The specific embodiment
How existing accompanying drawings the utility model is implemented
The anti-filter device of the utility model retaining wall draining, by vertical water permeability plastic row plate 1, laterally water permeability plastic row plate 2 and loaded filter 3 form, laterally water permeability plastic row plate 2 parallel interval settings, except the horizontal water permeability plastic row of bottom plate 2, all the other each layers are water permeability plastic row plate 2 laterally, connect minor face 2a and vertical water permeability plastic row plate 1 overlap joint by it, vertical water permeability plastic row plate 1 arranges according to the retaining wall 5 walls back of the body, the lower end of vertical water permeability plastic row plate 1 and horizontal water permeability plastic row plate bottom corresponding end, be inlaid in the loaded filter 3, loaded filter 3 leads to outside the retaining wall 5 by PVC gutter 4.
Described vertical, horizontal water permeability plastic row plate is rearranged by the porous plastics veneer.
The medial extremity of described horizontal water permeability plastic row plate 2 has vertical permeable connection minor face 2a.
The described vertical water permeability plastic row plate 1 that arranges according to the retaining wall back of the body is 0 degree ~ 15 degree with vertical plane upper end angle.
During construction:
The retaining wall 5 of constructing first, PVC gutter 4 wherein is set, the cohesive soil N of the horizontal water permeability plastic row of backfill bottom plate below 2 again, according to the retaining wall 5 walls back of the body vertical water permeability plastic row plate 1, the horizontal water permeability plastic row of bottom plate 2 and loaded filter 3 are set after backfill is complete, the lower end of vertical water permeability plastic row plate 1 and horizontal water permeability plastic row plate bottom corresponding end all are inlaid in the loaded filter 3; Then continue upwards backfill cohesive soil N, be backfilling into certain height horizontal water permeability plastic row plate 2 that be arranged in parallel with interval successively, each layer laterally water permeability plastic row plate 2 connects minor face 2a by it and overlaps with vertical water permeability plastic row plate 1.
