Flexible blocking screen for debris flow and flexible blocking dam for debris flow

Abstract

The invention discloses a flexible blocking screen for a debris flow and a flexible blocking dam for the debris flow and relates to the field of blocking facilities, and provides the flexible blockingscreen for the debris flow convenient to construct and the flexible blocking dam for the blocking dam. The flexible blocking dam for the debris flow comprises the flexible screen, a top supporting rope, a wingspan rope, a bottom supporting rope and an edge rope; the flexible screen is transversely unfolded, two ends of the flexible screen upwarp to form a flexible wingspan part, and the rest partis a flexible screen main body; the top supporting rope is transversely stretched to the top of the flexible screen main body, and the upper edge mesh of the flexible screen main body is slidably connected to the top supporting rope; the wingspan edge is arranged along the upper edge of the flexible screen, and the upper edge of the flexible screen is slidably connected to the bottom supporting rope; the bottom supporting rope is transversely stretched to the bottom of the flexible screen, and the lower edge mesh hole of the flexible screen is slidably connected to the bottom supporting rope;edge ropes are arranged at two ends of the flexible screen, and a side edge mesh hole of the flexible screen is slidably connected to the edge rope. The blocking screen is mounted in a cheuch to obtain the blocking dam.

Description

technical field [0001] The invention relates to the field of blocking facilities, in particular to a debris flow flexible blocking net and a debris flow flexible blocking dam. Background technique [0002] Debris flow is a special torrent in mountainous valleys, which is caused by torrents formed by heavy rainfall or melting ice and snow, and contains a large amount of solid materials such as sand and stones. Its characteristics are often sudden eruptions. The turbid fluid pushes forward and back along the steep ravine, gallops and roars down, the ground shakes, and the valley is like thunder. In a short period of time, a large amount of mud, sand and stones are washed out of the ditch, rampant and accumulated in a wide accumulation area, often causing great harm to human life and property. According to the shape of the debris flow ditch, it can be divided into ditch (river) valley type and hillside type debris flow. [0003] Common engineering prevention and control measu...

AI Technical Summary

Problems solved by technology

[0004] During the research and application of existing retaining structures in debris flow, it was found that many locations that need to be prevented from debris flow do not have the conditions for excavating foundations and transporting a large amount of raw materials such as concrete and stones, and large construction equipment cannot be reached, making construction difficult. The period is long, and the traditional structural retaining dam cannot be implemented, or the economic efficiency of the implementation is poor

In addition, traditional retaining dams have poor water permeability and are prone to damage such as hole plugging, water erosion, and cracking of the dam body

Furthermore, the traditional retaining dam has a weak ability to resist the load of a burst of debris flow
