Rock impact resistance spring lattice debris flow blocking structure

Abstract

A rock impact resistance spring lattice debris flow blocking structure comprises connecting nodes (5), wherein a plane groined structure consisting of I-shaped steel columns (1) and I-shaped steel beams (2) is arranged at the front part of an incident flow surface; the front I-shaped steel columns (1) and the I-shaped steel beams (2) are parallel to the incident flow surface with a reinforced concrete dam body at the rear part; springs (3) are arranged at groined beam column nodes and are perpendicular to the groined structural plan at the front part and the incident flow surface of the reinforced concrete dam body (6) at the rear part; spring protection sleeves (4) are arranged at the groined beam column nodes and are round steel pipes matched with the diameters of the springs; the spring protection sleeves (4) are pre-buried in corresponding positions of the incident flow surface of the corresponding reinforced concrete dam body (6); the two ends of the springs (3) are arranged at the groined beam column nodes and in the spring protection sleeves (4) of the reinforced concrete dam body (6); and the lower ends of the I-shaped steel columns (1) are fixed on a foundation of the reinforced concrete dam body (6).

Description

technical field [0001] The invention relates to the field of mud-rock flow blocking, in particular to a mud-rock flow blocking structure resistant to boulder impact. Background technique [0002] In the past, gravity-type solid retaining dams were mostly used for the prevention and control of debris flows. Gravity-type solid retaining dams can be built by masonry, plain concrete or reinforced concrete. This method mainly relies on the self-weight and stiffness of the retaining dam to reduce the impact of debris flow. The "Code for Design of Debris Flow Disaster Prevention and Control Engineering" has a detailed description of the gravity-type solid retaining dam. [0003] The disadvantages of gravity-type solid retaining dams are: (1) Poor ability to resist the impact of boulders; (2) Poor energy dissipation performance; (3) Self-heavy; (4) The direct contact with boulders is easy to damage. Based on the idea of ​​integrating energy consumption and protection, the present ...
