Description

Water discharging body

One) technical field

The utility model relates to a kind of water discharging body 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, soft basic draining or the like.In these drainage workss, the normal a kind of adrainage material that uses is the water discharging body of band drain groove, the water discharging body of band drain groove is made up of the water discharging body core body outsourcing geotextiles of band drain groove, be illustrated in figure 1 as its perspective view, self there is following shortcoming in this water discharging body: 1, displacement is atomic little, this water discharging body core is generally plastic material, extrude by plastic extruder, reason owing to manufacturing process, its size is very limited, common size such as plate are wide 10 centimetres, thick 0.4 centimetre, make displacement extremely small; 2, 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 water discharging body,, the whole drainage channel of water discharging body is compressed in a large number even stop up even if there is a short section phenomenon that is compressed shown in Figure 2 to occur, thereby the drainage efficiency of water discharging body is greatly reduced, and drainage effect is had a greatly reduced quality.Because above main cause makes the use of water discharging body very limited.

Three) summary of the invention

The purpose of this utility model is to provide a kind of have big water-flowing amount, anti-pressure ability is strong, drainage efficiency is high water discharging body.

The purpose of this utility model is achieved like this: comprise permeatable filter layer, it is characterized in that: also comprise the water discharging body core body that has drain groove, be outside equipped with Support Level at this water discharging body core body.

Described water discharging body core body can be a slot stick, also can be made of two above slot sticks, and each slot stick groove is outside, the backrest setting.

Can be provided with draining intercommunicating pore or seam in the drain groove on the described water discharging body core body, Support Level can be worn and be walked around the draining intercommunicating pore or seam is used for fixing or connects.

Permeatable filter layer outside the described water discharging body core body is outer can also to have swathed seam pressing line.

Described water discharging body core body can also be made of grid and slot stick, and the slot stick back side is arranged on the grid.

Described water discharging body core body can also be made of with slot stick dull and stereotyped, and the slot stick back side is arranged on the flat board.

Described water discharging body core body can also be for constituting by a vertical strip member of row with row's strip member that vertical strip member intersects, and side by side strip member in twos forms drain groove.

The end of described water discharging body core body can be has the member that constitutes the water discharging body core body with respect to other member elongate.

Groove on the described water discharging body core body can be the arc bamboo chip, also can be arc plastic sheet or cast iron sheet.

Described Support Level can helical form swathes the drain groove end face outside the water discharging body core body, and intersects with the conduit of drain groove.

Described Support Level also can be for latticed.

With regard to the material of described Support Level, Support Level can be plastics, glass fiber, nylon, cover the steel wire etc. of antirust coat outward, and shape of cross section can be platypelloid type.

Described permeatable filter layer can also can be the geotextile that is combined with geomembrane on the local area (as the area of cloth in a cloth one film geotextiles geotextiles greater than the area of film) for geotextile.

The utility model compared with prior art has the following advantages: 1, owing to can constitute the water discharging body core body by slot stick, its permeable amount and displacement all can be greatly improved, and make simple, cheap; 2, anti-pressure ability strengthens greatly, when Support Level is arranged at outside the water discharging body core body of being with drain groove, can form lattice shape with the cell wall of drain groove, perhaps Support Level is originally as grid, thereby the permeatable filter layer that firm support is covered outward, anti-pressure ability is strengthened, and the draining section area reduces for a short time under pressure, and drainage efficiency reaches raising.
