Construction method of gabion arch ecological flexible debris flow retaining dam

Abstract

The invention provides a gabion arch ecological flexible debris flow blocking dam and a building method of the gabion arch ecological flexible debris flow blocking dam. The gabion arch ecological flexible debris flow blocking dam is an arch-shaped blocking dam. According to the structure of the gabion arch ecological flexible debris flow blocking dam, gabion box pieces filled with rock ballast are stacked and piled on a foundation, and the gabion box pieces are bound, so that the integrality of the whole blocking dam structure is improved; waste tires filled with clinosol layer by layer are horizontally laid on the upstream face of the inner side of the gabion box pieces; ecological bags filled with clinosol layer by layer are piled on the downstream face of the inner side of the gabion box pieces; the areas between the waste tires and the ecological bags are filled with rock ballast which is compacted through vibrating. According to an optimal scheme, vegetation is placed in soil between layers of the waste tires and the ecological bags on the upstream side and the downstream side of the gabion arch blocking dam through cuttage, the plant anchor rod function and the ecological surface protection function are achieved, and then the gabion arch ecological flexible debris flow blocking dam is formed. The gabion arch ecological flexible debris flow blocking dam has the advantages that the mechanical design is reasonable, the construction technology is simple, cost is low, popularization is easy, the gabion arch ecological flexible debris flow blocking dam can replace a masonry blocking dam and a concrete dam which are prone to damage, and a debris flow disaster can be effectively prevented and handled.

Description

technical field [0001] The invention relates to an arch ecological flexible mud-rock flow retaining dam composed of gabion nets, waste tires and ecological bags in a mud-rock flow prevention project. The invention also relates to the gabion arch ecological flexible debris flow retaining dam and its construction method. The invention is especially suitable for retaining and storing the collapsed slope deposits in the source area of ​​medium and small-scale debris flow, and for blocking the debris flow in the circulation area. This invention overcomes the shortcomings of traditional hard retaining dams such as masonry and concrete retaining dams, better solves the problems of poor water permeability, impact resistance and insufficient durability of existing debris flow retaining structures, and realizes the protection of debris flow retaining structures and ecological protection. Organic combination of protection. [0002] The project of this invention is supported by the Mini...
