Laying device and method for impermeable films

Abstract

The invention discloses a laying device and method for impermeable films. The laying device for the impermeable films comprises a plurality of connecting assemblies and a film supplying device, the multiple connecting assemblies are arranged at intervals, the film supplying device is used for conveying the impermeable films, the two opposite ends of the impermeable films are connected to the two adjacent connecting assemblies correspondingly, each connecting assembly comprises a mounting part, two or more sets of waterproofing fixing assemblies and two or more connecting parts, each mounting part comprises a first mounting groove and a second mounting groove, the waterproofing fixing assemblies are arranged in the first mounting grooves and the second mounting grooves correspondingly, eachwaterproofing fixing assembly comprises two fixing parts, wherein a gap is formed between the two fixing parts, each connecting part is connected with the corresponding waterproofing fixing assemblyand comprises a first end and a second end, the first ends are connected to the waterproofing fixing assemblies, the second ends penetrate through the gaps, each connecting part is clamped by the twocorresponding fixing parts, and the second ends extend to the outer sides of the mounting parts and are used for being connected with the impermeable films. The laying device and method for the impermeable films, the impermeability and the waterproofing property of the junction of the adjacent impermeable films can be effectively achieved.

Description

Technical field [0001] The present invention relates to the technical field of underground anti-seepage, and more specifically, to a laying device and laying method of an anti-seepage membrane. Background technique [0002] In the course of construction operations in engineering industries such as mines, water conservancy, tunnels, and foundation pits, it is often encountered that aquifer (body) poses a hidden water hazard to the construction or causes great difficulties to normal construction, and it is necessary to intercept the aquifer (body). . The main methods include high-pressure jet grouting, concrete continuous walls and laying impervious membranes. [0003] High-pressure jet grouting is relatively simple and has low requirements on the construction site. However, it has higher requirements for drilling quality. The spread of the grout is greatly affected by the development of fissures in the target formation, the proportion of grout, and the grouting pressure. , The amo...
