Permeable turbulent flow type scouring protection device and evaluation method thereof
The invention provides a water-permeable turbulent flow type scouring protection device and an evaluation method thereof, and relates to the field of scouring protection. The protection device comprises a protection base and a permeable baffle, the protection base is a frustum-shaped shell with the high middle and the low periphery, and a center hole is formed in the protection base and used for being in positioning fit with a foundation pile body; a plurality of first water permeable holes are formed in the outer side surface of the protective base and are arranged at intervals in the circumferential direction of the central hole; the water-permeable baffle is fixed on the periphery of the protective base, and a plurality of second water-permeable holes are formed in the water-permeable baffle; the permeable baffle is further provided with a plurality of grooves, and bionic grass is installed in the grooves. The protective base is fixedly connected with the permeable baffle through a steel truss structure, bionic grass is further fixed to the steel truss structure, and a plurality of breeding ropes are connected between the upper portion of the protective base and the permeable baffle. The water permeable baffle and the protection base play a secondary energy dissipation role on water flow, the scouring protection effect is achieved, and the purpose of micro-ecological breeding is achieved under the combined action of the breeding rope and the bionic grass.
本发明提供了一种透水扰流型冲刷防护装置及其评价方法，涉及冲刷防护领域。该防护装置包括防护底座和透水挡板，防护底座为中间高、四周低的锥台形壳体，防护底座开设有中心孔，用于与基础桩体定位配合；防护底座的外侧面开设有多个第一透水孔，多个第一透水孔关于中心孔周向间隔布置；透水挡板固定于防护底座的外周，透水挡板上开设有多个第二透水孔；透水挡板还设有多个凹槽，凹槽中安装有仿生草；防护底座与透水挡板之间通过钢桁架结构固定连接，钢桁架结构上还固定有仿生草，防护底座的上部与透水挡板之间连接有多个养殖绳。通过透水挡板和防护底座对水流起到二级消能作用，实现冲刷防护效果，养殖绳与仿生草联合作用下实现微生态养殖目的。
