Problems solved by technology

Conventional trench anchorage and other forms need to be set at the middle platform of the slope. Setting the middle platform is equivalent to slowing down the angle of the entire slope, reducing the volume of the facility and reducing the engineering effectiveness

Embodiment 1

[0028] Such as figure 1 As shown, the geomembrane platform-free fixing device on the slope consists of A fixture 1, B fixture 2, clamp block 3, prestressed anchor rod 4, anchor head 5, backing plate 6, drill hole 7, and anchor body 8. Such as figure 2As shown, the top surface 1-1 of fixture A and the bottom surface 1-2 of fixture A form a certain angle, which is the same as the slope angle of slope 9, the left side 1-3 of fixture A and the right side 2-4 of fixture A and the bottom surface 1 of fixture A -2 vertical. The top surface 2-1 of fixture B and the bottom surface 2-2 of fixture B form a certain angle, which is the same as the slope angle of slope 9. The left side 2-3 of fixture B and the right side 2-4 of fixture B are perpendicular to the bottom surface 2-2 of fixture B. . The upper right part of the A fixture 1 is provided with a gap, the bottom surface 1-5 of the notch of the A fixture is parallel to the top surface 1-1 of the A fixture, and the angle formed by...

Abstract

The invention provides a geomembrane fixing device laid on a slope and belongs to the technical field of earthwork synthetic materials. The geomembrane fixing device comprises a clamp A, a clamp B, aclamp block and a geomembrane. A notch of the clamp A and a notch of the clamp B define a groove-shaped space. The clamp block matched with the groove-shaped space is arranged in the groove-shaped space. An oblique line formed by the upper end face formed after splicing of the clamp A, the clamp B and the clamp block has the consistent angle with the slope. The geomembrane is arranged between theclamp A, the clamp B and the clamp block. On the premise of not changing the continuity of the slope, the geomembrane is fixed to a slope foundation in a segmented mode, and the load-bearing length ofthe geomembrane is reduced equivalently, the geomembrane can be protected against breakage, and the anti-seepage effect can be ensured. As rivets are not adopted, the geomembrane is fixed without damage, and the anti-seepage function of the geomembrane is not destroyed.

Description

technical field [0001] The invention belongs to the technical field of geotechnical synthetic materials, and in particular relates to a geomembrane fixing device laid on a slope. Background technique [0002] Geomembrane is a flexible waterproof geosynthetic material with high anti-seepage ability and good chemical stability. It can resist the corrosion of strong acid, alkali and oil. It is a good anti-corrosion material and has good heat resistance. And cold resistance, long service life. [0003] Geomembranes can be divided into synthetic rubber and resins, mainly: high density polyethylene (High Density Polyethylene, HDPE); low density polyethylene (Low Density Polyethylene, LDPE); high flexible polyethylene (High Flexible Polyethylene, VFPE); Olefin thermoplastic elastomer (ThermoplasticPolyolefin, TPO); polypropylene (Polypropylene, PP); polyvinyl chloride (Polyvinyl Choride, PVC); EPDM (Ethylene Propylene Diene Monomer, EPDM), etc. Among resin and rubber geomembranes...
