AI Technical Summary

Technical Problem

In mine restoration and management projects, the construction of external flood interception ditch is difficult and the project volume is high, resulting in increased costs and insufficient interception and drainage, which is easy to lose the drainage function due to the accumulation of debris.

Method used

An external flood interception ditch structure was designed. The water-facing side of the ditch body was drilled to the fresh bedrock surface. The first ditch wall at the bottom of the ditch and the backwater side was made of reinforced concrete structure, and the second ditch wall on the water-facing side was made of permeable brick masonry structure, and gravel was backfilled in the ditch to filter the flow and block debris.

Benefits of technology

It reduces construction difficulty and project volume, improves the efficiency and long-term water interception and drainage, avoids waste of resources and additional treatment costs, and prevents trench blockage.

Abstract

The utility model belongs to the technical field of mine restoration, and particularly relates to an outer flood interception ditch structure for mine restoration and treatment engineering, which comprises a ditch body, the ditch body comprises a ditch bottom, a first ditch wall and a second ditch wall, the first ditch wall is arranged at one end of the ditch bottom close to a mine closure field, and the second ditch wall is arranged at one end of the ditch bottom far away from the mine closure field; the slope surface, close to the upstream side, of the ditch body is a fresh bedrock surface; the ditch bottom and the first ditch wall are both of a reinforced concrete structure, and the second ditch wall is of a water permeable brick masonry structure. The slope surface, close to the upstream side, of the ditch body is excavated to the fresh bedrock surface, and the long-term stability and safety of the ditch body are ensured by utilizing the characteristics that the fresh bedrock surface is not affected by weathering and has higher strength and stability; the ditch bottom and the first ditch wall of the ditch body are of a reinforced concrete structure, the second ditch wall is of a permeable brick masonry structure, the stability and durability of the ditch body are guaranteed, meanwhile, slope surface flowing water can be smoothly drained into the ditch body through the second ditch wall, and water accumulation is effectively prevented.
