Description

Technical Field

[0001] The invention relates to the field of natural disaster prevention and control, and in particular to a debris flow retaining structure capable of quickly adjusting the angle of a retaining wall panel. Background Art

[0002] Debris flow is a natural disaster that occurs only in mountainous areas. The mountainous area of ​​my country accounts for about two-thirds of the country's land area, and the number and frequency of debris flow disasters are very high. Debris flow is a complex multiphase fluid that carries a large number of solid materials such as stones and trees. It has the characteristics of complex causes, sudden outbreaks, and strong destructiveness, often causing huge casualties and economic losses.

[0003] At present, the protection against debris flow is mostly carried out by building retaining dams, diversion walls and other prevention and control files. The retaining structures in such prevention and control plans are mostly cast-in-place reinforced concrete structures, which are only suitable for construction in relatively flat locations of debris flow channels. This limits the choice of location for retaining structures and is not suitable for debris flow channel management with complex channel structures. Cast-in-place reinforced concrete structures have a long construction period, high project costs, and are very cumbersome to repair or dismantle the structures at a later stage. In order to better protect the safety of buildings and people's lives downstream of debris flow, it is particularly important to construct a debris flow retaining structure system that is both economical and safe, simple and reusable and suitable for any channel structure.

[0006] Furthermore, the debris flow retaining structure capable of quickly adjusting the angle of the retaining wall panel is characterized in that square drainage holes are staggered on the prefabricated retaining wall panel, and a metal shaft mounting hole is reserved under the panel.
