Description

The stereo channel water discharging body

Utility model relates to the stereo channel water discharging body of a kind of underdrainage and structure draining.

At present, in engineerings such as building, agricultural, often must carry out the draining of the soil body or structure inside, as dewatering, the row's of cutting underground water, the barricade back of the body, abutment draining, highway central zone draining or the like.In these drainage workss, normally used adrainage material has flexible porous tube (as shown in Figure 1), flexible porous tube is made up of the outer bag of steel coil geotextiles, change the seepage flow state and be pipe stream, drainage efficiency is improved a lot, but self there are two big shortcomings in it, the one, can not stand lateral force, easily be compacted machinery and overwhelm flattening, thereby lose drainage effect; The 2nd, flexible porous tube is arranged warp parallel closely for reinforcement setting, has significantly reduced permeable efficient, and its use is very limited;

The french drain (as shown in Figure 2) that other is made up of the three-dimensional netted external bag geotextiles that a kind of plastics long filament twines, this french drain only is a seepage flow drainage principle of having simulated the rubble french drain, therefore drainage efficiency is not high, and anti-pressure ability is also not enough, distortion is bigger under pressure, influence its draining, its drainage efficiency is reduced more, cost is also higher.

The purpose of this utility model is to provide a kind of compressive strength height, stereo channel water discharging body that 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 coated on the central layer periphery of band drain groove, is provided with the mesh reinforcement layer between the central layer of permeatable filter layer and band drain groove; Described drain groove is provided with draining intercommunicating pore or seam.

The central layer of described band drain groove is overlapped into rectangle or trapezoidal.

Be provided with flat board with holes between the central layer of the folded band of described two-phase drain groove.

The material of described permeatable filter layer is a geotextiles.

The utility model compared with prior art has the following advantages: 1, owing to the support that drain groove is arranged, and the reinforcement of reticulate body, so anti-pressure ability is strong; 2, owing to the effect that blocks water that does not exist as the compact arranged warp parallel of flexible porous tube, so the permeability rate height; 3, the utility model is equivalent to the sinuate percolation path of french drain seepage water has been made into the shortest straight line path, and the long-pending increase of cross section of fluid channel, changes seepage flow and is the pipe stream mode, has therefore improved drainage efficiency greatly.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the flexible porous tube structural representation;

The structural representation of the french drain that the three-dimensional netted external bag geotextiles of Fig. 2 is formed;

Fig. 3 is the cross sectional view of the utility model embodiment one;

Fig. 4 is embodiment illustrated in fig. 3 one perspective view;

Fig. 5 is the cross sectional view of the utility model embodiment two;

Fig. 6 is the cross sectional view of the utility model embodiment three;

Fig. 7 is the structural representation of perforated plastic flat board among the embodiment three;

Fig. 8 is the perspective view of the utility model embodiment four.

Shown in Fig. 3,4, present embodiment one comprises " U " core plate of permeatable filter layer and one deck band drain groove, the material of permeatable filter layer is a geotextiles, carrying out wraparound in central layer 1 periphery of band drain groove with plastic wire 2 back-up coats pastes, the also available glass fiber grid of plastic wire replaces, in plastic wire 2 back-up coat coated outside one deck geotextiles 3, the geotextiles that wherein is wrapped in central layer 1 bottom surface is waterproof again, and geotextiles 3 can bond or sew up or directly wrap; Also wrapped multiple geotextiles as required, these geotextiles wherein one side are permeable, and are also can multiaspect permeable or all permeable; Draining intercommunicating pore 5 is arranged on the drain groove 4, can make circulation mutually between the groove 4, the also available seam of these draining intercommunicating pores replaces.More than the central layer of band drain groove can be made of plastic, by the plastic extruder extrusion modling; Hole on the draining core body or seam can be through the secondary operations moulding of plastics.

As shown in Figure 5, present embodiment two is basic identical with embodiment one, and difference is to adopt the central layer of difform band drain groove, and present embodiment two adopts " ten " core plate.

As shown in Figure 6, present embodiment three is overlapped into rectangle by the central layer 1 of two-layer band drain groove, and these draining central layers adopt " ten " type, also can be other shape; Be bonded with plastic board with holes 6 (as shown in Figure 7) between the central layer of the folded band of two-phase drain groove; Plastic wire 2 wraparounds also stick on edge, drain groove 4 top, the two-layer geotextiles 3 of plastic wire 2 outer wrapping, and every layer of geotextiles all connects with sewing up, and the suture location of inside and outside two-layer geotextiles staggers, and can prevent the infiltration of fine particle like this.

As shown in Figure 8, present embodiment four is overlapped into trapezoidal by the central layer 1 of being with drain groove, and these draining central layers are for falling T-shape, non-caked plastic board with holes between the draining central layer; The draining central layer that these are superimposed together can be pasted plastic wire 2 back-up coats in its left and right side and end face wraparound, wrap up one deck geotextiles 3 more outside, this geotextiles that is wrapped in draining central layer bottom surface can not percolating water, carries out colligation with rope 7 at a certain distance at the length direction of water discharging body and strengthens.
