Water filling type rubber dam sand scouring and discharging system used for silting preventing behind long piled wharf

Abstract

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.

Description

technical field [0001] The invention relates to an underwater sediment anti-silting device behind a wharf, in particular to a water-filled rubber dam flushing and sand-discharging system used for anti-silting behind a high-piled wharf. Background technique [0002] At present, the traditional methods used to solve the problem of sediment back-silting behind the wharf include the diversion embankment sand method, cutter suction dredger dredging method, trailing suction dredger dredging method, machine-boat towed dredging method, etc. Among them, the sand diversion dike method mainly surrounds the wharf by dikes, changes the flow direction of the tidal current field, and blocks the sediment from the wharf. Occupying a large area of ​​sea area, the construction cost is high. The other three methods all require the use of dredgers. However, due to the dense foundation piles of the wharf and the fact that some wharves still do not meet the height requirements for the dredger to ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the traditional methods for dredging behind the wharf that require regular dredging, consume a lot of manpower, material and financial resources, take a long time for dredging, and inconvenient construction, the present invention proposes a water-filled rubber dam flushing The sand discharge system is applied behind the berths of the built wharf to realize the flushing effect of the sediment during the ebb and flow of tides
