AI Technical Summary

Technical Problem

Existing impermeable geotextiles have poor sealing at the overlaps, which can easily lead to water seepage and affect the stability of the soil.

Method used

It adopts rubber geotextile substrate and waterproof components, including hot melt pads, waterproof layers, mounting parts, protrusions, fasteners, connecting components and waterproof components. The connection is strengthened by hot melt joints and semi-vulcanized structure. Combined with waterproof geomembrane, geotextile filter material and drainage net core material, it enhances waterproof performance and structural strength and prevents leakage.

Benefits of technology

It improves the sealing of geotextile overlaps, prevents water seepage, enhances soil stability and service life, adapts to long-term loads and harsh environments, and reduces construction costs.

Abstract

The utility model relates to the technical field of high polymer materials, in particular to geotechnical cloth capable of preventing water seepage after lap joint, which comprises a rubber geotechnical cloth base material and a waterproof component, and the waterproof component comprises two hot melting pads, two waterproof layers, a mounting piece, a bump, a fixing piece, two connecting components and a waterproof component. The hot melting pads are fixed to the two ends of the rubber geotechnical cloth base material and used for reinforcing connection between the rubber geotechnical cloth base material and the waterproof layer, leakage is avoided, when the side edges of the rubber geotechnical cloth base material need to be connected, the protruding blocks on the mounting pieces on the side edges are matched with the limiting grooves in the fixing pieces, and the connecting components are used for sealing and reinforcing connection; the waterproof performance of the surface of the rubber geotechnical cloth base material is enhanced through the waterproof layer and the waterproof component, the connecting position is sealed through the connecting component, connection is enhanced, and the problem that the stability of a soil body is affected due to the fact that in existing water-seepage-proof geotechnical cloth, the lap joint position of the geotechnical cloth is poor in sealing performance and water seepage is prone to occurring is solved.
