Technical Field
The utility model belongs to the technical field of the engineering material, specific saying relates to a novel geomembrane that is used for afforestation protection engineering such as river, lake embankment to administer, highway subgrade side slope protection.
Background
The geomembrane takes plastic films such as polyvinyl chloride (PVC), Polyethylene (PE), ethylene/vinyl acetate copolymer (EVA) and the like as anti-seepage base materials, and is compounded with non-woven fabrics to form the geomembrane made of the anti-seepage material for the geotechnical engineering. The mechanism is that the water leakage channel of the earth dam is separated by the impermeability of the plastic film, and the non-woven fabric formed by the high polymer short fiber chemical material has higher tensile strength and elongation to bear water pressure and adapt to the deformation of the dam body.
In order to further improve the tear resistance and the water pressure bearing performance of the geomembrane, the utility model with the Chinese patent number of 201020148726.7 and the grant publication number of CN201771002U discloses a composite geomembrane. Namely, the side surface of the non-woven fabric layer forming the geomembrane layer is provided with a reinforcing layer formed by woven fabric or net made of materials such as glass fiber, polypropylene and the like.
The geomembrane as a water leakage path of the earth dam has high strength, but when the geomembrane of the structure is used in a construction structure of an artificial irrigation canal such as a north-south water diversion, the purpose is to prevent leakage of canal water. The geomembrane has excellent seepage-proofing effect in arid areas with low groundwater level, but surface water or groundwater with high pressure can flow, permeate and overflow to the side wall forming the irrigation canal in areas with high groundwater level or in rainy season in arid areas; the lower the topography of irrigation canal is the water yield that overflows just is big, and the pressure to the irrigation canal bottom and the irrigation canal lateral wall that forms with closely knit bonded geomembrane of slope and cement is just big to along with the continuous increase of irrigation canal lateral wall department ponding volume, then can directly push away the lateral wall and split or push away, cause the use of irrigation canal to be limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can be at any time with irrigation canal lateral wall ponding exhaust novel geomembrane.
In order to achieve the above object, the utility model adopts the following technical scheme:
a novel geomembrane, comprises an anti-seepage base material and is characterized in that: supporting components are arranged on the inner side face of the anti-seepage base material at intervals to form a supporting structure, and a geotextile layer with water seepage performance is arranged outside the supporting structure.
The additional technical characteristics of the novel geomembrane also comprise:
-the support elements constituting the support structure are of a saw-tooth or wave-like structure;
the impermeable substrate comprises a plastic film structure and a plate structure;
-providing a reinforcing layer on the plastic film constituting the impermeable substrate;
-a reinforcing layer is arranged on the geotextile layer.
The utility model provides a novel geomembrane compares with prior art, has following advantage: firstly, because the structure forming the novel geomembrane comprises the seepage-proofing base material, the supporting structure and the geotextile layers arranged outside the seepage-proofing base material and the supporting structure, a water permeable channel is formed between the seepage-proofing base material and the geotextile layers, namely, seepage water on the side wall of the irrigation canal enters the water permeable channel through the geotextile tightly attached to the slope side wall and flows into the ponding channel arranged at the bottom of the canal, the effect of draining ponding on the side wall of the irrigation canal at any time can be realized, the damage of the ponding on the side wall of the canal is effectively prevented, and the service life of the canal is prolonged; and secondly, the plastic film forming the anti-seepage base material is provided with the reinforcing layer, so that the service life of the novel geomembrane can be greatly prolonged.

Detailed Description
The structure of the novel geomembrane provided by the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the structure of the novel geomembrane provided by the present invention is schematically illustrated. The structure of the novel geomembrane comprises an anti-seepage base material 1 formed by a plastic film (or a plastic plate with the thickness of more than 0.5 mm), a supporting structure formed by supporting components 2 formed by a sawtooth (or wave) shaped concave-convex structure is arranged on the inner side surface of the anti-seepage base material at intervals, a geotextile layer 3 with water seepage performance is adhered to the outside of the supporting layer structure, namely, the outer surface of the geomembrane structure is a concave structure which is formed by a convex 21 corresponding to the supporting structure to form a water flow channel 5 and a concave 22 corresponding to the position without the supporting components (namely, the geotextile layer is directly adhered with the plastic film layer).
When in use, as shown in fig. 2, the geotextile layer 3 forming the geomembrane is directly attached to the side wall of the ditch or the bottom 4 of the ditch, the side wall seepage water or the groundwater can seep into the channel 5 formed by the wave-shaped concave-convex structure of the supporting component through the geotextile layer 3 with the seepage function, and the seepage water or the groundwater can be collected into the pipeline network 6 which is arranged at the bottom of the ditch and is provided with the check valve through the channel and is discharged through the check valve 7; because the surface adhered to the side wall or the bottom 4 of the canal is a structure formed by a convex part 21 corresponding to the support structure and a concave part 22 corresponding to the position without the support component, the adhesion area between the two parts can be increased, and the adhesion strength between the geomembrane and the side wall or the bottom 4 of the canal is improved.
As shown in fig. 3 and 6, the structure of the second novel geomembrane provided by the present invention is schematically illustrated. Namely, a supporting structure formed by supporting components 2 formed by a sawtooth (or wave) shaped concave-convex structure is continuously arranged on the inner side surface of the anti-seepage base material, a geotextile layer 3 with water seepage performance is adhered to the outside of the supporting layer structure, namely, the geotextile layer forming the geomembrane structure and a continuous water flowing channel 5 corresponding to the supporting structure are formed.
The supporting structure in the geomembrane can be a wave or zigzag structure as shown in fig. 1 and 2, or a nipple (bump) array structure 9 as shown in fig. 4 and 5, i.e. the space around each nipple (bump) is an interconnecting structure, so that the formed channel 5 is an interconnecting structure, which is more beneficial to the balanced circulation of water seepage.
The novel geomembrane of the supporting structure formed by the supporting components 2 arranged on the inner side surface of the impermeable base material at intervals as shown in fig. 1 is preferably used in a way that the channel 5 formed as shown in fig. 2 is vertically used from top to bottom, and even water seepage can flow into the pipeline network 6 arranged at the bottom of the ditch along the channel; of course, the water can also be used in a horizontal and vertical mode, and the water can also enter the channel through the lateral slope of the ditch and is collected into the pipeline network 6.
In order to further improve the tensile strength of the geomembrane, as shown in fig. 1, 3, 4, 5 and 6, a reinforcing layer 8 formed by mesh cloth can be arranged on the waterproof base layer 1 or/and the geotextile layer 3.
