Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Example one

As shown in fig. 1, 2 and 3, the utility model discloses a linear drainage geomembrane, including geomembrane body 1, be provided with a plurality of water drainage tank 2 of arranging side by side on the geomembrane body 1, water drainage tank 2's both ends are respectively switched on and are had first takeover 3 and second takeover 4, the internal diameter of first takeover 3 equals with the external diameter of second takeover 4, the both sides wing of geomembrane body 1 top surface still is provided with the adapting unit who links up two geomembrane bodies 1.

The drainage channel 2 is provided with 5 strips. In this application scheme, for the display function effect with look over clearly, only be provided with 5 water drainage tank 2. In practical application, can add water drainage tank 2 according to measuring drainage condition on the spot, drainage demand, add water drainage tank 2 through the equidistant of die sinking, and then mass production.

And 5 drainage grooves 2 are arranged on the geomembrane body 1 at equal intervals. The drainage grooves 2 which are arranged at equal intervals are beneficial to drainage operation, and the condition of accumulated water is avoided.

The inner groove surface of the drainage groove 2 is designed to be a cambered surface. The water discharge groove 2 with the inner diameter of the cambered surface can increase the water capacity, the larger discharge capacity can be realized under the condition of containing more water, and water flows from one end with high ground potential in the water discharge groove 2 to one end with low ground potential.

Two longitudinally adjacent geomembrane bodies 1 are connected end to end through a first connecting pipe 3 and a second connecting pipe 4 in a nested manner, and the two transversely adjacent geomembrane bodies 1 are connected through a connecting part.

The first connecting pipe 3 and the second connecting pipe 4 of two longitudinally adjacent geomembrane bodies 1 are oppositely arranged and are mutually communicated by nesting the first connecting pipe 3 into the second connecting pipe 4. According to the actual area of on-the-spot laying, take corresponding quantity's geomembrane body 1, through end to end increase total length, both sides link up and increase total width, realize laying regional area. When the two geomembrane bodies are connected end to end, the first connecting pipes 3 and the second connecting pipes 4 of the two geomembrane bodies 1 correspond to each other one by one and are nested with each other. Since the first connecting pipe 3 can be just nested in the second connecting pipe 4, the friction force at the joint can ensure that the first connecting pipe 3 and the second connecting pipe 4 can be stably nested and connected, and water cannot leak out from the joint.

The connecting part comprises a lock catch 5 and a lock hole 6 which are matched with each other, and the lock catch 5 and the lock hole 6 are respectively and correspondingly arranged on the left side and the right side of the geomembrane body 1.

Hasp

5 and 6 symmetries of lockhole set up in the both sides of geomembrane body 1, and hasp 5 is two hasp structures, and lockhole 6 is two keyhole structures, stability when can increase the linking. The lock catch 5 on one geomembrane body 1 is aligned to the lock hole 6 on the other geomembrane body 1, and the lower end of the lock catch 5 is pressed into the lock hole 6, so that stable connection is realized.

The geomembrane body 1 is cut into 30m or 50m in length and 6m in width. During production, the steel wire rope is cut into a specification with a proper length according to actual requirements, and is rolled up, so that the steel wire rope is convenient to transport and lay. Wherein the axial direction of the drainage channel 2 is the length of the geomembrane body 1, and the axial direction perpendicular to the drainage channel 2 is the width of the geomembrane body 1.

The thickness of geomembrane body 1 is 3mm or 5 mm.

Example two

On the basis of the first embodiment, the present embodiment provides a specific implementation flow of the linear drainage geomembrane.

The specific implementation principle flow is as follows:

in the construction, firstly, sand or clay with smaller material diameter is used for leveling the base surface, and then the geomembrane is laid. The base surface is cleaned according to the design requirement, which is the key for ensuring the anti-seepage effect, particularly, impurities such as sharp stones, tree roots and the like are thoroughly cleaned, the base surface is not allowed to have local concave-convex phenomenon, and the cleaned base surface is tamped by a tamping hammer or a tamping plate to be compact and flat. When the membrane is paved, one surface of the drainage groove faces upwards, and large-area communicated paving is realized through the alignment nesting of the first connecting pipe and the second connecting pipe between the membranes and the fastening of the connecting parts (replacing the traditional mode of coating emulsified asphalt with the thickness of 2mm at the connecting part). The film should be pressed and adhered to each other and the film should be pressed and adhered to the base surface, but the film should not be pulled too tightly, generally slightly loose, but no air bubbles should be left at the bottom of the film. Because the geomembrane is thin and light, and is very easy to blow by wind after being laid before the protective layer is laid, the area of one-time membrane laying is not suitable to be large, and the membrane is preferably laid while the protective layer is covered with soil. And then, a transition layer of about 10cm is paved on the paved geomembrane by fine sand or clay, and a block of stone (or concrete precast block) of 20-30cm is laid as an anti-impact protective layer. During construction, the stone should be prevented from directly hitting the geomembrane, and the construction of the protective layer is preferably carried out while the geomembrane is laid. The connection of the geomembrane and the peripheral structures is anchored by adopting expansion bolts and steel plate pressing strips.

Through setting up the water drainage tank, can discharge the ponding that ground oozes down, avoid road surface structure layer and road bed to receive water to soak, reduce the emergence of phenomenons such as roadbed face disease, avoid the potential safety hazard. The utility model can reduce the cost of materials and labor and increase the economic benefit; meanwhile, the process steps during laying are reduced, the workload is reduced, and the engineering time is shortened; the paving is convenient and quick, the stability of the engineering pavement is protected, and the working efficiency is improved.
