Description

A kind of porous disc

One) technical field

The utility model relates to a kind of porous disc of getting rid of infiltration.

Two) background technology

At present, in engineerings such as building, agricultural, the often eliminating that must seep water, as dewatering, the row's of cutting underground water, the barricade back of the body, abutment draining or the like.In these drainage workss, the normal a kind of adrainage material that uses is the porous disc of band drain groove, the porous disc of band drain groove is made up of the porous disc central layer outsourcing geotextiles of band drain groove, be illustrated in figure 1 as its perspective view, self there is following shortcoming in this porous disc: anti-pressure ability is low, under ambient pressure, be easy to the geotextile that covers is outward compressed into drain groove, shown in the sectional view of Fig. 2, and in the vertical length range of porous disc, even if there is a short section phenomenon that is compressed shown in Figure 2 to occur, the whole drainage channel of porous disc is compressed in a large number even stop up, thereby the drainage efficiency of porous disc is greatly reduced, and drainage effect is had a greatly reduced quality.

Three) summary of the invention

The purpose of this utility model is to provide the porous disc that a kind of anti-pressure ability is strong, drainage efficiency is high.

The purpose of this utility model is achieved like this: comprise the central layer of permeatable filter layer and band drain groove, permeatable filter layer is arranged at outside the central layer of band drain groove, it is characterized in that: swathed Support Level on the porous disc central layer of described band drain groove.

Described Support Level can be plastics, glass fiber, nylon, cover the steel wire etc. of antirust coat outward, and less than 2 centimetres, shape of cross section can be platypelloid type perpendicular to the cross section length of side of length direction for it.

Described Support Level can swathe into the rectangular coil shape on the central layer of band drain groove, also can swathe into other shapes such as trellis.

Described Support Level can be arranged on the central layer of band drain groove, also can add Support Level again on permeatable filter layer.

Can reserve draining intercommunicating pore or seam on the described drain groove.Support Level can be worn and be walked around the draining intercommunicating pore or seam is used for fixing or connects.

The central layer of described band drain groove can be overlapped into rectangle or trapezoidal or polygon.

Can add flat board with holes or add clathrum between the central layer of the folded band of described two-phase drain groove.

The outer available grids shape thing of the central layer of described band drain groove is strengthened supporting.

Described permeatable filter layer comprises the water permeability geotextiles that is combined with geomembrane on water permeability geotextiles and the local area (as the area of cloth in a cloth one film geotextiles geotextiles greater than the area of film).

The utility model water discharging body can be provided with geomembrane on one to three face, and makes at least one face of the utility model eliminating infiltration body permeable.

The utility model compared with prior art has the following advantages: anti-pressure ability strengthens greatly, when Support Level is arranged on the central layer of being with drain groove, can form lattice shape with the cell wall of drain groove, perhaps Support Level itself is formed lattice shape, thereby the permeatable filter layer that firm support is covered outward, anti-pressure ability is strengthened, and the draining section area reduces lessly under pressure, and drainage efficiency reaches raising.
