Problems solved by technology

[0003] At present, the main problems of traditional grid dams are: (1) The design flow velocity of debris flow is considered according to the average flow velocity, which does not reflect the flow velocity of the "tongue-shaped body" presented in the evolution process, which is large in the middle and small on both sides, and the "leading" is from the top to the top. The spatial distribution characteristic of the surface flow velocity is greater than the bottom flow velocity when falling down; (2) When resisting the impact of debris flow, the structure itself

Example Embodiment

[0030] The present invention is further explained in the following description, which is apparent from the following examples, which will be described below in conjunction with the description. Based on the embodiments in the present application, one of ordinary skill in the art is in the scope of the present application without making creative labor premistence.

[0031] Embodiments of the present invention is directed to energy by the structure itself, the reinforcing structure itself required strength to resist debris flow dam in the conventional impact, stiffness and ductility of the methods to ensure their safety, resulting in many defects, thereby providing a damping energy dissipation cell debris flow dam gate, debris flow control is applied, of course, embodiments of the present invention is also applicable to hydrological management, control, and many other geological consume fluid energy required to block the art.

Abstract

The invention discloses a damping energy dissipation type debris flow grid dam and a construction method thereof. The invention aims to have stronger impact resistance, a safe and reliable structure,and small cross-sectional size of components, easy installation and disassembly, and cost saving. The damping energy dissipation type debris flow grid dam comprises a front flow surface grid structureand a back flow surface frame structure which are arranged apart and opposed to each other, and a damping component arranged between the front flow surface grid structure and the back flow surface frame structure. The damping component comprises a first damper and a second damper. The first damper is arranged horizontally. Two ends of the first damper are respectively connected with the front flow surface grid structure and the back flow surface frame structure. The second damper is arranged obliquely. Two ends of the second damper are respectively connected to the front flow surface grid structure and the back flow surface frame structure.

Description

technical field [0001] The invention relates to the field of debris flow prevention and control engineering, in particular to a damping energy-consuming debris flow grid dam and a construction method thereof. Background technique [0002] When a debris flow occurs, it carries a large amount of solid matter such as sand, stones, etc., and its volume content can reach about 13%-80%, which is extremely destructive. The grid dam can store most of the large solid matter in the debris flow, drain away the free water in the sediment, fine gravel and fluid, achieve the effect of water and rock separation, reduce the density, flow and scale of the debris flow, and reduce the downstream damage caused by the debris flow Degree. Therefore, grid dams are widely used in debris flow prevention and control projects. [0003] At present, the main problems of traditional grid dams are: (1) The design flow velocity of debris flow is considered according to the average flow velocity, which do...
