Water filling type rubber dam sand scouring and discharging system used for silting preventing behind long piled wharf
The invention discloses a water filling type rubber dam sand scouring and discharging system used for silting preventing behind a long piled wharf. The sand scouring and discharging system comprises an anchor rod fixed to a bottom bed, a bottom plate on the top of the anchor rod, a fixing anchor for fixed connection of a rubber dam and the bottom plate, a water filling type rubber dam, a water filling pipeline, a water pressure meter, a water inflating valve and a water pump, wherein the water pressure meter, the water inflating valve and the water pump are arranged on a back sea wall. The portability of the water filling type rubber dam is utilized, the concept of water bundling sand scouring is applied, the water filling type rubber dam is arranged behind the wharf, the water pump arranged on the back sea wall is used for conducting water filling on the rubber dam, and the effect of a traditional dam is achieved. Since the area of a water passing fracture surface of a dam body is reduced, the water flow speed of the area between the top of the rubber dam and the rear edge of the wharf is increased, the scouring function is generated for the bottom bed, and the soil lateral pressure exerted on a pile foundation is reduced. After operation is finished, step-by-step water discharging can be conducted for dam bag collapsing and falling, and recycling and reutilizing are conducted. The water filling type rubber dam sand scouring and discharging system solves the problems about sediment return silting, construction inconvenience and the like, wherein the problems commonly existbehind the wharf.
本发明公开了一种用于高桩码头后方防淤的充水式橡胶坝冲排沙系统，该冲排沙系统包括固定在底床上的锚杆、锚杆顶部的底板、用于将橡胶坝与底板相连固定的固定锚、充水式橡胶坝、充水管道、布置在后方海堤上的水压表、充水阀和水泵。本发明利用充水式橡胶坝的便携性，运用束水冲沙的理念，在码头后方布置充水式橡胶坝，通过布置在后方海堤上的水泵对橡胶坝进行充水，达到传统堤坝的效果，由于坝体减小了过水断面的面积，在橡胶坝坝顶与码头后沿之间的区域水流流速增大，对底床产生冲刷作用，减小桩基所受侧向土压力。当作业完成后，可通过逐步排水，使坝袋坍落，进行回收再利用。本发明解决了码头后方普遍存在的泥沙回淤以及施工的不便性等问题。
