Riverbed protection device with wading bridge and protection method
The invention relates to the technical field of wading bridge foundation scour protection, in particular to a riverbed protection device with a wading bridge and a protection method. The riverbed protection device includes an aeration blowing system for introducing gas into river water to reduce the scour of a river bed by the water flow at bridge piers, a parameter detection unit for detecting water flow parameters and a control system for sending instructions to the aeration blowing system based on data obtained by the parameter detection unit; and the output end of the parameter detection unit is connected with the input end of the control system, and the output end of the control system is connected with the input end of the aeration blowing system. When the gas at a certain pressure is introduced into the river water from the riverbed surface, the water flow structure around the bridge piers can be changed, sediment around the bridge piers is prevented from being taken away due tothe fact that the diving of the water flow in fronts of the bridge piers or turbulent eddies around the bridge piers is prevented from scouring the river bed, so that the impact of the water flow ona bridge foundation is reduced, and the stability of the bridge foundation is ensured.
本发明涉及涉水桥梁基础冲刷防护技术领域，具体是涉及一种具有涉水桥梁的河床防护装置及防护方法。包括用于向河水中通入气体以减小在桥墩处水流对河床冲刷的鼓风曝气系统，用于检测水流参数的参数检测单元，用于依据参数检测单元获取的数据向鼓风曝气系统发送指令的控制系统；参数检测单元的输出端连接控制系统的输入端，控制系统的输出端连接鼓风曝气系统的输入端。从河床面向河水中通入一定压力的气体，能够改变桥墩周围水流结构，阻碍桥墩前水流下潜或桥墩周边湍流漩涡对河床的冲刷而带走桥墩周围的泥沙，来降低水流对桥梁基础的影响，保证桥梁基础稳定。
