Embodiment Construction

[0036] The following describes the specific embodiments of the present invention to facilitate those skilled in the art to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments, for those of ordinary skill in the art, as long as various changes These changes are obvious within the spirit and scope of the present invention defined and determined by the appended claims, and all inventions and creations that utilize the concept of the present invention are protected.

[0037] Such as figure 1 As shown (the present invention has continuity, only three horizontal platform 2 and corresponding other components are shown in the figure. If you need to set the horizontal platform 2 to other numbers, you only need to figure 1 Add horizontal caps 2 and other corresponding components to both sides on the basis of the flexible net. The flexible net debris flow dam includes a number of concrete buttresses 1 fo...

Abstract

The invention discloses a debris flow sand retaining dam with a flexible mesh and a construction method thereof. The sand retaining dam includes several concrete buttresses for dividing a wide mud and rock flow channel into a number of suitable width ranges for the flexible mesh, and the concrete buttresses are stepped. Rise up and set in sequence from bottom to top as the first step, the second step and the third step; each concrete buttress is provided with a lateral tooth sill in the longitudinal middle of the side with the adjacent concrete buttress; the concrete The bottom of the pier is provided with a horizontal cap, and the bottom of the horizontal cap is provided with anti-slip tooth sills and several steel pipe piles. The structure of the invention is simple in construction and saves investment, and can be used for blocking mud-rock flows in large and wide ditches. When the debris flow comes, the debris flow is divided into multiple strands by the concrete pier, and then accumulates under the action of the flexible net barrier between the adjacent first steps. Accumulate under the action to realize the control of debris flow.

Description

Technical field [0001] The invention relates to the field of debris flow channel treatment engineering, in particular to a flexible mesh debris flow sand dam and a construction method thereof. Background technique [0002] Debris flow refers to a special torrent of landslides caused by heavy rains, snowstorms or other natural disasters in mountainous areas or other areas with deep ravines and steep terrains and carrying large amounts of sand and rocks. Debris flow has the characteristics of suddenness, fast velocity, large flow, large material capacity and strong destructive power. The occurrence of mudslides often washes away roads, railways and other transportation facilities and even villages and towns, causing huge losses. [0003] Debris flow is a torrential flow formed by torrential rains and floods that contain sand and rock and soft soil mountains are saturated and diluted. Its area, volume and flow are large, while landslides are areas with a small area of ​​diluted soil....
