AI Technical Summary

Technical Problem

In existing technologies, the horn-shaped protrusions at the top of the structure wall result in low laying efficiency, poor safety, and difficulty in ensuring the quality of geomembrane. In particular, when working at heights, the varying skill levels of construction workers make it difficult to guarantee flatness and tension uniformity, thus affecting the seepage prevention effect.

Method used

A geomembrane laying device for solid hazardous waste landfills was designed, including a support frame, a vertical cylinder, a horizontal cylinder, and a clamping arm. Through pneumatic control valve assembly and intelligent controller, the geomembrane is tightly bonded to the wall. Infrared markers are used to assist in positioning and the walking clamping mechanism to improve construction safety.

Benefits of technology

It improves the efficiency of geomembrane laying, ensures the seepage prevention effect, reduces the workload of construction workers, enhances construction safety, and the device has a simple structure, low cost, and can adapt to the laying needs of walls of different specifications.

Abstract

The application belongs to the technical field of geomembrane laying and relates to a solid hazardous waste landfill site geomembrane laying device and laying method, which comprises a support frame, a vertical air cylinder, a first horizontal air cylinder, a first clamping arm and a clamping part. The support frame comprises two longitudinal rods, a first horizontal rod and a second horizontal rod connected with the two longitudinal rods. One end of the vertical air cylinder is detachably fixedly connected with the upper end surface of a structure wall, and the other end of the vertical air cylinder is fixedly connected with the two longitudinal rods through a support frame connector. The application can make the anti-seepage geomembrane on both sides of the solid hazardous waste landfill site wall closely adhere to the wall surface near the upper end of the structure wall, effectively solve the problem of laying the anti-seepage geomembrane on the upper end of various structure walls including a horn-shaped protruding structure, a plane, a concave shape, an arc shape and the like, improve the geomembrane laying efficiency and construction safety, and ensure the anti-seepage effect after the geomembrane is laid.
