Water-air sand flushing equipment for silt prevention and desilting of long-piled wharf
The water-air sand flushing equipment comprises exhaust equipment, high-pressure water jet equipment and an outer frame, an exhaust hole is formed in the bottom of the exhaust equipment, and a water jet hole is formed in the bottom of the high-pressure water jet equipment. The device focuses on desilting behind the wharf, is directly arranged on sludge and is not limited by the wharf structure; water power is enhanced through water jet and gas transportation to a water body, and sediment starting is carried out; meanwhile, sediment is driven to suspend and transport by utilizing the floating and diffusion characteristics of gas in a water body, and efficient and low-consumption desilting is performed by fully utilizing hydrodynamic force; after the dredging work is completed, the device can also be used for preventing silt, suspension of silt is maintained through continuous exhaust, silt falling is avoided, and the silt prevention effect is achieved.
本发明公开了一种用于高桩码头防淤清淤的水‑气冲沙设备，包括排气设备、高压水射流设备和外框架，所述排气设备底部开设有排气孔，所述高压水射流设备底部开设有水射流孔。本发明侧重于码头后方的清淤，直接布置于淤泥之上，不受码头结构的限制；并通过水射流和向水体输运气体，加强水动力进行泥沙起动；同时利用气体在水体中上浮和扩散特性带动泥沙悬浮和输运，充分利用水动力高效低耗的进行清淤；在清淤工作完成后，本发明还可用于防淤，通过持续的排气来维持泥沙的悬浮，避免泥沙落淤，达到防淤效果。
