Floating plate device for deposition promotion and strengthening of sunken fascine mattress

Abstract

The invention relates to a floating plate device for deposition promotion and strengthening of a sunken fascine mattress. The floating plate device comprises an inflation floating plate, anchor piles and hanging ropes. The inflation floating plate is made of waterproof and weatherproof flexible materials. The inflation floating plate is in a plate shape after being inflated with air. The thickness of the inflated floating plate is controlled through plate inner reinforced belts, and the strength of the floating plate is improved by adding reinforcement strips outside longitudinal plates and transverse plates which are arranged on the double faces. The height of holes in the lower edge of the floating plate is controlled with the length of the hanging ropes for bottom high-sand-content water to pass. The anchor piles are anchored in silt of a bottom bed and connected with the inflation floating plate through the hanging ropes, anchoring force is provided for the inflation floating plate, the modular design is adopted in the floating plate device, the floating plate device can be installed on a large area of an area easy to scour, and scouring protection and silt deposition promotion are carried out. When the installed floating plate reaches the sand deposition promoting limit, the upper edge of the floating plate can be connected and provided with a next-period floating plate device, and the function of deposition promoting continues to be performed. Compared with the prior art, the floating plate device has the beneficial effects that cost is low, installing is convenient, modular design and self protection are achieved, and the underwater ecological environment can be improved.

Description

technical field [0001] The invention relates to an underwater floating plate, in particular to a floating plate device used for sinking, discharging and promoting reinforcement. Background technique [0002] The sediment on the riverbed and seabed is in the dynamic balance of erosion and deposition for a long time. When the sediment-carrying capacity of the water flow is greater than its sediment content, the dynamic balance is destroyed, and the sediment on the bed surface is washed and cut down; otherwise, the sediment-carrying capacity of the water flow is less than its sediment content. If the amount of sand is high, the sedimentation will rise. Local scouring of the river bed will not only change the river regime and the direction of the main channel, affect the safety of ships, but also cause disasters such as bank collapse, which seriously threatens the safety of river embankments and the safety of people's lives and property. Improving the local anti-scour performan...

Problems solved by technology

However, the sinking row that has been used for many years will fail due to various reasons. For example, after the local weak position of the sinking row breaks and wears through, it will be washed away with the ever-expanding sediment below the sinking row, endangering the stability of the sinking row.

After the sinking protection fails, due to its underwater construction characteristics, its maintenance cost is very high
