Title:
ANTI-IMPACT DUAL-CAVITY IMPACT-MITIGATION-TYPE DISSIPATION STRUCTURE FOR BRIDGE PROJECT AND DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2022/011567
Kind Code:
A1
Abstract:
The present invention relates to civil engineering, and specifically relates to an anti-impact dual-cavity impact-mitigation-type dissipation structure for a bridge project and a design method. The dissipation structure comprises a blocking dam and a dissipation system provided upstream of the bridge project; the dissipation system comprises discharge tunnels, dissipation cavities, and a discharge guide tunnel; both the number of the discharge tunnels and the number of the dissipation cavities are two; each discharge tunnel has one end communicated with a channel upstream of the blocking dam, and the other end communicated with one end of one dissipation cavity; the outlet axis direction of the end of each discharge tunnel communicated with the dissipation cavity and the axis direction of the dissipation cavity are located on different planes; the other ends of the two dissipation cavities are communicated with the discharge guide tunnel, and the discharge guide tunnel is communicated with a channel downstream of the blocking dam; and the top of each dissipation cavity is provided with a vent hole for communicating the dissipation cavity with the atmosphere. The design method is used for designing the dissipation structure. The dissipation structure provided by the present invention can dissipate the kinetic energy of mud flows, and substantially reduces the impact of the mud flows on the bridge project.
