Construction method of a debris flow retaining dam

Abstract

The invention discloses a construction method for a mud-rock flow retaining dam. Bottom discharge outlets (2) are arranged at intervals at the bottom of the masonry retaining dam (1), and dams are arranged at intervals at the dam body of the masonry retaining dam (1). The body drain hole (4), the top drainage piles are arranged at intervals on the upper part of the masonry retaining dam (1); the rigid mesh clip gravel flexible water permeable structure is constructed in the middle and upper part of the masonry retaining dam (1) body (6); a plurality of closely arranged discarded tires (3) are arranged on the upstream face of the masonry retaining dam (1); anti-skid teeth ( 7), the anti-slip teeth (7) are poured in the anti-slip teeth grooves excavated at the dam foot of the masonry retaining dam (1). The invention not only increases the flexibility of the dam body, but also has good water permeability, and can quickly infiltrate and discharge the water in the accumulation body intercepted by the debris flow retaining dam, thereby ensuring the safety and stability of the retaining dam, thereby reducing or eliminating the hazard of debris flow.

Description

technical field [0001] The invention relates to a rock flow retaining dam and a construction method thereof, which belong to the technical fields of civil engineering technology and mountain disaster prevention engineering, and are suitable for use in areas prone to debris flow in the upstream of important buildings such as tailing ponds or bridges, railways, and expressways. It is used to block possible debris flows to avoid damage to tailings ponds or important buildings, and is especially suitable for building debris flow retaining dams upstream of tailings ponds in valleys. Background technique [0002] Debris flow refers to a special torrent carrying a large amount of sediment and stones due to landslides caused by heavy rain, snowstorm or other natural disasters in mountainous areas or other areas with deep valleys and steep terrain. Due to its strong impact and silting ability , and has the characteristics of suddenness, fast flow, large flow, large material capacity ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a debris flow impact energy that can effectively reduce the debris flow impact energy and increase the The construction method of the mud-rock flow retaining dam that improves the water permeability of the body, so as to eliminate the harm of the mud-rock flow to the downstream major construction projects
