AI Technical Summary

Technical Problem

Existing slope protection structures are easily damaged and difficult to clean when faced with high-energy rockfalls, and the existing protection structures have high investment costs and poor adaptability.

Method used

A tiered filtering slope rockfall barrier structure is designed, employing multi-stage flexible rockfall barriers with progressively smaller mesh sizes and progressively increased material strength. Combined with a support system and anchoring structure, it achieves tiered energy dissipation and graded interception. The flexible mesh material and support system disperse the impact energy of falling rocks, and rockfall stagnation zones are set up for easy cleanup.

Benefits of technology

It achieves efficient protection, improves protection level and reliability, reduces maintenance difficulty and cost, and is highly adaptable and economical.

Abstract

The present application belongs to the technical field of slope protection engineering, and particularly relates to a step-by-step filtering type slope rock blocking structure, which comprises a plurality of levels of blocking units arranged along the slope surface from top to bottom at intervals, and a support system; each level of blocking unit comprises at least one vertically arranged flexible filtering rock blocking wall; the support system comprises a vertical suspension cable anchored to the slope, which is used for suspending and supporting each level of rock blocking wall; preferably, the mesh size of each level of rock blocking wall is gradually reduced and / or the material strength is gradually increased, so as to realize step-by-step consumption of rockfall impact energy and graded filtering and blocking of rockfalls of different particle sizes; a rockfall stagnation area is formed between adjacent blocking units, facilitating segmented cleaning and maintenance. Through the concept of "soft against hard and step-by-step energy dissipation", the present application effectively solves the problems of easy damage of a single protection structure, limited blocking capacity and difficult maintenance under high-energy rockfall impact, and has the advantages of high protection efficiency, strong adaptability, good economy and convenient maintenance.
