Title:
DISSIPATION STRUCTURE FOR DEBRIS FLOW PREVENTION OF BRIDGE ENGINEERING AND DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2022/011569
Kind Code:
A1
Abstract:
The present invention relates to civil engineering, and in particular, to a dissipation structure for debris flow prevention of bridge engineering and a design method. The dissipation structure comprises a dissipation system and a blocking dam provided upstream of a bridge. The dissipation system is provided in a slope body on the side of a channel and comprises a discharge hole, a dissipation cavity, and a drainage hole. One end of the discharge hole is communicated with a channel located upstream of the blocking dam, the other end of the discharge hole is communicated with one end of the dissipation cavity, and the outlet axis direction of the end of the discharge hole communicated with the dissipation cavity and the axial direction of the dissipation cavity are on different planes. The other end of the dissipation cavity is communicated with the drainage hole, and the drainage hole is communicated with a channel located downstream of the blocking dam. A vent hole is formed above the dissipation cavity and is used for communicating the dissipation cavity with the air. A plurality of protruding structures is arranged on the inner wall of the dissipation cavity. The design method is used for designing the dissipation structure. A pier can be protected by dissipating debris flow kinetic energy, the debris flow energy is directly dissipated from sources, repair and maintenance are convenient, and the bridge body structure is not influenced.
