Abstract

The utility model relates to a degradable plastic water drainage plate, which is used for draining water in an underground soil layer. The water drainage plate is composed of a degradable plastic core plate and externally wrapped geotextile. Parallel clapboards are uniformly distributed both on the front surface and the reverse surface of the degradable plastic core plate. Water drainage grooves are arranged among the parallel clapboards. Two joint ends of the geotextile are overlapped with each other. The two overlapped layers are hot pressed and blended. The water drainage plate has strong water drainage function in the early stage of being embedded in the soil layer; the intensity of the core plate is high; the plastic core plate can be automatically degraded underground after about one year; then, the water drainage plate stops draining water; and the foundation settlement phenomenon after completion of works is avoided.

Description

The degradation plastic band drain

Technical field

The utility model relates to a kind of band drain that is used to get rid of underground soil layer water, particularly a kind of degradation plastic band drain.

Background technology

In the civil engineering, no matter be that building, football field, park or first stage of construction such as railway, highway all need to carry out draining to soft base earlier and handle, the water in the underground weak soil layer discharged that dewatering prevents to take place from now on the problem of setting of ground.The plastic draining board that is widely used in recent years has drain function preferably.Plastic draining board is made up of plastic plate core and the geotextiles wrapped up in outward; Plastic draining board contains the rhone that is arranged in parallel; With certain spacing distance plastic draining board is inserted soft subgrade soil layer depth place; Underground water promptly can see through geotextiles and get into the plastic plate core, discharges earthward through rhone, and the silt rubble then is trapped in the soil layer by geotextiles.Mostly the central layer of existing plastic draining board is corrugated sheet, and drainage efficiency is lower, and intensity is relatively poor.In addition, the seam of the geotextiles that central layer is wrapped up in outward generally adopts the method for sewing, and the seam crossing of geotextiles is together sewed up together with quilted plastic panel, and the suture needle meeting takies the multiple tracks rhone, and these rhones are damaged, and influences drainage effect.Another kind of method commonly used is to adopt chemical bonding agent that the seam of geotextiles is bonding, because the band drain consumption is very big in the engineering, a large amount of chemical bonding agents can cause environment pollution.Main is the equal non-degradable of existing quilted plastic panel, has drain function for a long time, deposits ground and continues the hidden danger of sinking.

Summary of the invention

The new purpose of this practicality provides a kind of intensity height, drainage efficiency is high; The degradation plastic band drain that no chemical agent pollutes; And quilted plastic panel can be after assigning certain hour with imbedding degraded is damaged voluntarily, make rhone and lose drain function, avoid the later stage setting of ground.

This degradation plastic band drain is made up of degredation plastic central layer and the geotextiles wrapped up in outward; Degredation plastic central layer tow sides are evenly equipped with parallel baffle; Be rhone between the parallel baffle, said geotextiles two seam ends are superimposed mutually, and two overlapping layers hot pressing fuse continuous.

The double-edged parallel baffle of said degredation plastic central layer misplaces each other and arranges.

For point type fuses, fuse some distribution discontinuously in superimposed district between the two seam end overlapping layerss of said geotextiles.

The material of the central layer of the utility model band drain is a degredation plastic; Tow sides are equipped with rhone, and drain function is strong, and drainage efficiency is high; The parallel baffle that dislocation is arranged can increase the intensity of central layer; Wrap up in outward and adopt hot pressing to connect between the geotextiles seam crossing overlapping layers, can not destroy the rhone of central layer, also do not produce environment pollution.What this band drain was imbedded the soil layer has very strong drain function in early days, and quilted plastic panel stops draining in underground degraded voluntarily after 1 year.Avoid occurring behind the completion of works phenomenon of ground (like railway ground) sedimentation.

Description of drawings

Fig. 1 is the end face structure sketch map of the utility model band drain.

Fig. 2 is that the A of Fig. 1 is to partial sectional view.

Among the figure, the 1-quilted plastic panel, 1-1,1-2-parallel baffle, the 2-rhone, the 3-geotextiles, 4-fuses a little.

The specific embodiment

Like Fig. 1 and Fig. 2, the front of degredation plastic central layer 1 is evenly equipped with parallel baffle 1-1, reverse side is evenly equipped with parallel baffle 1-2, and shifts to install at tow sides; It between the parallel baffle rhone 2; Fig. 1 is visible, and the arrangement that misplaces each other of double-edged rhone 2 is the mouth organ general layout.

Degredation plastic central layer 1 is wrapped with geotextiles 3, and two seam ends are superimposed mutually about geotextiles, and hot pressing fuses continuously between two overlapping layerss, and expression geotechnique is furnished with a plurality of hot pressing spaced apart and fuses a little 4 among Fig. 2.

It is dark that this band drain is assigned tens of rice with vertically inserting, and underground water promptly sees through geotextiles 3, goes into quilted plastic panel 1 back and rise to the ground discharge along each rhone 2, and soft soil layer is descended, and ground is firm.Quilted plastic panel 1 is a degredation plastic, gets rid of underground water approximately after the several months or about 1 year with this band drain, and central layer promptly can be degraded voluntarily, and drainage channel is blocked automatically, stops draining, thereby can avoid ground to continue to sink.

Claims

1. degradation plastic band drain; Being made up of degredation plastic central layer and the geotextiles wrapped up in outward, it is characterized in that degredation plastic central layer tow sides are evenly equipped with parallel baffle, is rhone between the parallel baffle; Said geotextiles two seam ends are superimposed mutually, and two overlapping layers hot pressing fuse.

2. degradation plastic band drain according to claim 1 is characterized in that the double-edged parallel baffle of said degredation plastic central layer misplaces each other to arrange.

3. degradation plastic band drain according to claim 1 and 2 is characterized in that between the two seam end overlapping layerss of said geotextiles for point type fuses, and fuses a little in superimposed district to being interrupted distribution.
