Semi-submersible layered scour prevention and siltation promotion device
The invention discloses a semi-submersible layered scour prevention and siltation promotion device. The device is composed of a plurality of floating body units, the floating body units are of layeredstructures, the upper layers are of flexible simulation plants, the middle layers are of suspension block bodies, the lower layers are of siltation promoting and flow slowing plates, and the floatingbody units are connected into a whole through flexible ropes and anchored to a riverbed through light anchor chains. According to the device, the middle-layer suspension block bodies are suspended ina water body, and the river channel water flow structure near the device is changed through the synergistic effect of the upper-layer flexible simulation plants and the lower-layer siltation promoting and flow slowing plates, so that the effect of reducing kinetic energy of suspended loads and bed loads in the water body is achieved, and the purpose of static deposition of silt in a specific areais achieved; the device is stable and reasonable in structure, remarkable in scour prevention and siltation promotion effect, small in influence on river flood discharge, high in economic index, convenient to install and maintain and convenient in spatial position adjustment; and meanwhile, the water body environment around the device can be improved, and the biodiversity of the water body is improved.
本发明公开了一种半潜式分层防冲促淤装置，该装置由多个浮体单元组成，浮体单元采用分层结构，上层为柔性仿真植物，中层为悬浮块体，下层为促淤缓流板，浮体单元间通过柔性绳索连接成一个整体，并通过轻质锚链将装置锚固于河床。该装置利用中层悬浮块体悬浮于水体中，利用上层柔性仿真植物以及下层促淤缓流板协同作用，改变装置附近的河道水流结构，对水体中悬移质和推移质均有消减动能的作用，达到泥沙在特定区域静止沉积的目的。该装置结构稳定合理、防冲促淤效果显著、对河道泄洪影响小、经济指标高、安装、维护以及空间位置调整方便。同时，有利于改善装置周围的水体环境以及提高水体的生物多样性。
