AI Technical Summary
Technical Problem
Conventional geosynthetic mats face issues with environmental pollution due to separation and disposal, as well as inadequate sealing and mechanical stability, particularly when installed on slopes or in morphologically changing environments.
Method used
A geosynthetic mat composed of biodegradable materials for the cover layers and connection structure, with a controlled biodegradation rate and swelling behavior, ensuring sufficient backpressure and shear strength over time to maintain sealing and stability.
Benefits of technology
The mat achieves long-term sealing and mechanical stability while minimizing environmental pollution by ensuring controlled biodegradation and expansion, maintaining effective sealing and preventing slope slippage.

Abstract
The present invention relates to a geosynthetic mat comprising an upper cover layer and a lower cover layer, and a middle filler layer disposed between the upper cover layer and the lower cover layer and composed of a filler layer material containing an expandable material. The present invention is characterized in that the top cover layer and / or the bottom cover layer is / are composed of a biodegradable material or contain a biodegradable material, and the peel strength is characterized by the degree of residual peel strength at a predetermined time point after the start of the biodegradation process. The degree of this residual peel strength is formed by the square of the quotient of the reduced peel strength of the connection structure between the upper cover layer and the lower cover layer at a predetermined time and the initial peel strength of the connection structure between the upper cover layer and the lower cover layer before the start of the biodegradation process.
