GCL vertical laying structural member and construction process thereof

Abstract

The invention discloses a GCL vertical laying structural member and a construction process thereof. The construction process comprises excavating a groove for laying a vertical anti-seepage special GCL composite component layer; using a GCL composite component vertical laying device or a specially made lifting appliance to place the vertical anti-seepage special GCL composite component layer in the groove; rolling and attaching the laid vertical anti-seepage special GCL composite component layer to a groove wall by a rolling roller; lowering a joint box or a two-in-one joint box, wherein an overlapping area can be rolled for many times to ensure tight fit and improve the anti-seepage performance of the overlapping area. The GCL vertical laying structural member and the construction processthereof have the beneficial effects that the GCL vertical laying construction process is researched and developed according to practical engineering conditions such as the property of flexible anti-seepage coiled materials such as GCL, the construction characteristics of vertical laying and the construction characteristics of an anti-seepage wall, mechanized construction is adopted, the operationis simple and safe, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the field of construction, in particular to a GCL vertical laying structure and a construction process thereof. Background technique [0002] With the development of economy and society, some water conservancy and environmental protection projects put forward higher requirements for vertical anti-seepage, especially some polluted sites need to take vertical anti-seepage measures to prevent pollutants from penetrating into the surroundings and polluting the environment. However, conventional vertical anti-seepage walls are limited by materials and processes, and relying solely on the anti-seepage performance of their own walls can no longer meet the requirements. [0003] Commonly used high-performance waterproof and anti-seepage materials, such as GCL and geomembrane, have been widely used in the field of anti-seepage, but due to construction restrictions, the applications are mostly concentrated in the horizontal direction.

AI Technical Summary

Problems solved by technology

The laying device of the vertical anti-seepage membrane invented by the patent CN205224120 U only solves the problem of whether laying can be done, but cannot guarantee the laying quality of the product; The difficulty of operation, the depth of each groove may be different, and there are high requirements for product production. In addition, the L-shaped push rod needs to be equipped with special supporting machinery, so this construction plan is difficult
