Description

Technical Field

[0001] This utility model belongs to the field of drainage structure technology, specifically relating to drainage structure for rock-based revetment. Background Technology

[0002] To prevent landslides and collapses on natural bank slopes, rigid slope protection works such as concrete or masonry are often constructed. When the slope foundation is rock, the rigid slope protection blocks groundwater seepage channels, necessitating the installation of effective drainage systems to ensure the smooth drainage of groundwater within the slope. This prevents groundwater accumulation, backwatering, frost heave, and other issues that could cause bulging, misalignment, slippage, and cracking of the slope structure. Existing slope protection drainage systems primarily involve installing DN50–100mm UPVC drainage pipes on the slope surface, spaced 2–3 meters apart. These pipes penetrate the rigid revetment and extend into the slope soil, with the ends wrapped with geotextile for backfiltration. However, during operation, the small pipe diameter and limited drainage capacity make these systems prone to siltation, freezing, and breakage, posing significant safety hazards, making maintenance inconvenient and costly.
