AI Technical Summary
Technical Problem
In existing debris flow control, common debris dam structures such as masonry and concrete are prone to causing surface disturbance and damage during construction, and have high material requirements.
Method used
The structure adopts a permeable slag barrier dam, including a roller-compacted dam body, a rockfill scour protection layer and an anti-scour layer. It utilizes geogrids, drainage pipes and no-fines concrete layers, and the materials are readily available locally, reducing disturbance.
Benefits of technology
It achieves structural stability, permeability, and erosion resistance, avoids disturbance and damage during construction, and allows materials to be sourced locally, reducing environmental impact.

Abstract
The application relates to a water-permeable slag retaining dam which comprises a roller compacted dam body, a rockfill anti-scour layer and a scouring-resistant layer. The roller compacted dam body is transversely arranged in a ditch body. The roller compacted dam body comprises multiple layers of geogrids and multiple drainage pipes. The multiple layers of geogrids are arranged in layers along the height direction of the roller compacted dam body. The multiple drainage pipes are arranged in the roller compacted dam body at intervals. The drainage pipes are connected with the upstream side and the downstream side of the roller compacted dam body. The rockfill anti-scour layer is arranged on the upstream side of the roller compacted dam body. The rockfill anti-scour layer has a preset stacking thickness. The scouring-resistant layer comprises a sand-free concrete layer. The sand-free concrete layer is arranged on the downstream side of the roller compacted dam body. The sand-free concrete layer has a preset stacking thickness. The water-permeable slag retaining dam needs simple materials, can be conveniently obtained from the site, and can effectively avoid disturbance or damage caused in the construction process.
