Embodiment Construction

[0008] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention is a zigzag stone flow retaining structure, the front part is the anti-collision pier 1 made of reinforced concrete evenly arranged according to the equal interval a, the cross-sectional shape of the anti-collision pier 1 is isosceles trapezoidal; the rear part is the steel bar The dam body 2 made of concrete, the anti-collision pier 1 is parallel to the upstream surface of the dam body 2, the anti-collision pier 1 and the dam body 2 are poured at the same time during construction, and become a whole, and the integral foundation 3 is adopted.

[0009] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the arrangement of anti-collision piers 1 follows the following principle: the number x of anti-collision piers 1 within every 20m along the length of the dam body is not less than 4 and not more than 6.

[0010] The cross-section of the anti-collision pier 1 is an isosc...

Abstract

The invention relates to a sawtooth-shaped debris flow blocking structure. The front part of the structure is provided with reinforced concrete anti-collision piers (1), the anti-collision piers (1) are uniformly arranged at equal intervals of a, and the cross section of each anti-collision pier (1) is in an isosceles trapezoid shape. The back part of the structure is provided with a reinforced concrete dam body (2), and the anti-collision piers (1) are parallel with an upstream surface of the dam body (2). The anti-collision piers (1) and the dam body (2) are simultaneously cast into a whole during construction, and an integral foundation (3) is adopted.

Description

technical field [0001] The invention relates to the field of debris flow retaining structures, in particular to a gravity retaining structure. Background technique [0002] In the past, solid gravity retaining dams were mostly used for the prevention and control of debris flows, which mainly relied on the self-weight and stiffness of the dam body to resist the impact of debris flows. The "Code for Design of Debris Flow Disaster Prevention and Control Engineering" has a detailed description of the solid gravity retaining dam. [0003] The disadvantages of solid gravity retaining dams are: (1) large volume; (2) self-heavy; (3) low utilization rate of material strength; (4) relatively poor resistance to boulder impact. Contents of the invention [0004] The purpose of the present invention is to provide a more effective impact-resistant debris flow retaining structure. [0005] The present invention is a zigzag stone flow retaining structure, the front part is the anti-coll...
