AI Technical Summary

Technical Problem

Existing valley structures present problems such as high construction difficulty, high cost, poor stability, and slow ecological restoration. In particular, the full-section excavation method damages the original landform and ecology and has high maintenance costs.

Method used

The overflow weir-type valley structure is adopted, including a gabion stepped dam body, vertical gabion walls and seepage prevention walls. Excavation is only carried out at the toe of the slope on the side of the ditch to reduce the amount of excavation. Plain soil is laid between the seepage prevention walls and Amorpha fruticosa is planted to form a stable ecological slope protection.

Benefits of technology

It achieves low-cost, high-stability, and easy-to-construct ditch management, reduces construction disturbance, preserves the original landform and vegetation, and enhances the long-term stability and eco-friendliness of the project.

Abstract

This utility model relates to the field of hydraulic engineering technology, specifically an overflow weir-type gabion. The gabion includes: a gabion dam body, which is a gabion structure distributed in several stepped layers. The uppermost layer of the dam body has an overflow outlet for drainage. The dam body is located at the bottom of the erosion gully; two sets of vertical gabion walls, located on either side of the dam body; and several slope-mounted anti-seepage walls, spaced apart on the outside of the two sets of vertical gabion walls and laid on the surface of the erosion gully slope. This utility model avoids the need for vertical excavation to both sides of the gully banks during shoulder construction, which causes large-scale disturbance to the original slope and damages the original soil structure. It also significantly reduces the amount of excavated earth. Simultaneously, the stepped energy dissipation structure effectively reduces the energy of the incoming water, further reducing the size of the main structure and the amount of materials used. This significantly shortens construction costs and time, improving the long-term stability and durability of the project.
