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...

Examples

Embodiment 1

[0030] as follows Figure 1~4 As shown in the figure, a floating plate device for sinking, drainage and silting reinforcement includes a floating plate 1, a hanging rope 2 and an anchor pile 3. After the floating plate 1 is inflated, it becomes a rectangular plate with a length of 3m and a height of 1m. A slab external reinforcement strip 11 is arranged every 0.25m in the vertical and horizontal directions. Inside the buoyant plate 1 , there are evenly provided with inner reinforcing bands 12 to control the thickness of the inflated inflatable plate 13 . The upper and lower edges of the inflatable board 13 are evenly provided with a plurality of hanging rings 14, and the hanging rings 14 are directly connected to the outer ribs 11 of the board. An air injection port 15 is respectively arranged at the bottom of both sides of the inflatable board 13 .

[0031] The inflatable board 13 is made of a waterproof and weather-resistant flexible material. It is plate-shaped after infl...

Embodiment 2

[0036] Embodiment 2: Due to the silt-promoting function of the floating plate 1, the sand coming from the upstream will continuously silt on its upstream and downstream sides. However, when the thickness of the silt deposit reaches the silt limit of the floating plate 1, the bed scour and silt presents a dynamic balance, and the silt deposit stops, specifically as follows: Image 6 with Figure 7 shown. At this point, if you wish to continue promoting silt, you can heighten the existing floating plate 1 . Since the floating plate 1 is a modularized standard component, it is easy to realize its heightened assembly requirements. The second-stage floating board is the heightened component. After the heightening, it will continue to play the function of promoting sedimentation, so that the sediment that promotes sedimentation reaches a new thickness. By analogy, through the installation of multi-stage floating boards, the design can be achieved. Thickness of sediment-accelerate...
