Technical Field
[0001] The invention relates to the field of engineering construction, in particular to a blowing and filling device for solidifying soil around offshore piles. Background Art
[0002] Against the backdrop of the depletion of fossil energy and the severe climate change situation, wind energy has become a renewable, clean energy with little environmental impact, and its strategic value is increasingly prominent. All countries attach great importance to wind energy. Moreover, large offshore power plants are a new market industry, and similar engineering construction experience is very scarce. Offshore wind power projects face turbulent water flow and thick plastic silt layers. After the offshore steel pipe piles are sunk, a vortex-shaped scour pit is easily formed around the piles. It is urgent to develop a device for blowing and filling solidified soil around offshore piles to prevent the discharge speed from being too fast and solve the problem of slurry being washed away. Summary of the invention
[0003] In order to reduce the speed of solidified soil blowing and filling and reduce slurry loss, the present application provides a solidified soil blowing and filling distribution device around offshore piles.
[0004] The present application provides a device for distributing soil blowing filling around offshore piles, which adopts the following technical solution:
[0005] A blowing and distributing device for solidified soil around offshore piles comprises a crane, a pump and a pump head. The crane is installed on a barge used in conjunction with the distributing device. The crane is rotatably installed on the barge used in conjunction with the distributing device. Both sides of the barge along the length direction are provided with material pools for placing solidified soil. The pump head is slidably installed on the hook of the crane along the length direction of the crane's boom; the pump is fixedly installed on the barge, and the pump is connected to the pump head through a pipeline.
[0006] By adopting the above technical solution, workers first move the barge to the water area where material needs to be laid, then start the crane, and lift the pump head to the bottom of the water near the steel pipe piles through the hook; start the pump, and transfer the solidified soil stored in the barge material pool to the pump head through the pipeline and blow it to the bottom of the water; and the pump head is slidably installed on the boom, and the position of the pump head can be changed by moving the crane, so that material can be laid in different areas of the bottom of the water.
[0007] Preferably, a fastening assembly for compacting the solidified soil after pumping is installed on the pump head.
[0008] By adopting the above technical solution, in order to reduce the situation where the solidified soil is washed away by water after being blown out, resulting in insufficient slurry around the pile, after the solidified soil is blown out, the fastening assembly is started to compact the solidified soil to reduce the loss of the solidified soil.
[0009] Preferably, the fastening assembly includes a box body and a pair of pressure rollers, the box body is fixed with the output end of the pump head, and the pump head is connected to the inner cavity of the box body; the lower end of the box body is open, and the two pressure rollers are rotatably installed at both ends of the box body along the length direction.
[0010] By adopting the above technical solution, after the pump head is lowered to the bottom of the water around the pile, the barge is started to blow out the slurry while dragging the pump head. At this time, the box moves together with the pump head, and the pressure roller in the box compacts the solidified soil under its own gravity, reducing the loss of solidified soil slurry.
[0011] Preferably, the rotating shaft of each of the pressing rollers is slidably mounted on the inner wall of the box body along the vertical direction, each of the pressing rollers is hollow, and a counterweight is arranged inside each of the pressing rollers.
[0012] When the box moves on the bottom of the water, underwater rocks may collide with the pressure roller, causing damage to the pressure roller. By adopting the above technical solution, when encountering rocks, the pressure roller moves in the vertical direction under the guidance of its own outer wall, thereby reducing direct collision with the rocks. At the same time, the provision of a counterweight can enable the pressure roller to always have a tendency to slide downward in the vertical direction, so that the pressure roller can quickly reset after colliding with the stone and sliding, while further enhancing the compaction effect of the pressure roller on the solidified soil slurry.
[0013] Preferably, the counterweight member comprises a counterweight block, and the counterweight block is sleeved on the rotating shaft of the pressure roller.
[0014] By adopting the above technical solution, the counterweight block is arranged in the pressure roller, so that the counterweight block can play a stable role.
[0015] Preferably, the output end of the pump head is located in the box body and a plurality of buffer boxes are provided. The pump head is connected to each of the buffer boxes through a pipeline. A discharge port is provided at the bottom of each buffer box, and the discharge port is used to release the solidified soil entering the buffer box through the pump head.
[0016] By adopting the above technical solution, the solidified soil slurry flows into each buffer box after passing through the pump head, thereby dispersing the slurry in the pump head and reducing the slurry discharge speed, so that the slurry can self-level on the bottom of the water and spread to the bottom of the water around the pile, reducing the solidified soil loss rate.
[0017] Preferably, the suspension arm is provided with a guide rail along its length direction, the pump head is slidably mounted on the guide rail, and the suspension arm is provided with a driving member for driving the pump head to slide on the guide rail.
[0018] By adopting the above technical solution, after the driving member is started, the pump head is driven to slide on the guide rail, and the guide rail fixes the sliding path of the pump head, thereby improving the sliding stability of the pump head.
[0019] Preferably, the driving member includes a roller and a driving motor, the roller is fixedly mounted on the hook, and the roller is rollingly mounted on the guide rail; the driving motor is fixedly mounted on the hook and the output shaft of the driving motor is connected to the rotating shaft of the roller via a belt and pulley set.
[0020] By adopting the above technical solution, after starting the driving motor, the roller rolls on the guide rail, thereby driving the pump head fixedly connected to the roller to slide on the guide rail; the sliding friction is converted into rolling friction by the roller, thereby reducing the obstacles to the sliding of the pump head.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. Workers first move the barge to the water area where material distribution is required, then start the crane and lift the pump head to the bottom of the water near the steel pipe pile through the hook; start the pump to transfer the solidified soil stored in the barge material pool to the pump head through the pipeline and blow it out to the bottom of the water; the pump head is installed on the boom in a sliding manner, and the position of the pump head can be changed by moving the crane, so as to distribute material to different areas of the bottom of the water;
[0023] 2. The solidified soil slurry flows into each buffer box after passing through the pump head, thereby dispersing the slurry in the pump head and reducing the slurry discharge speed, so that the slurry can self-level on the bottom of the water and spread to the bottom of the water around the pile, reducing the loss rate of the solidified soil.

[0030] The present application discloses a device for distributing solidified soil blowing filling around offshore piles. Figure 1 and Figure 2The offshore pile surrounding solidified soil blowing filling material distribution device comprises a crane 1, a pump 2 and a pump head 3. The crane 1 is rotatably installed on a barge used in conjunction with the material distribution device, so that the position of the pump head 3 can be adjusted according to the on-site conditions to facilitate the blowing filling of solidified soil; the barge is provided with material pools 4 for placing solidified soil on both sides along the length direction, and the pump head 3 is slidably installed on the hook 12 of the crane 1 along the length direction of the boom 11 of the crane 1; the pump 2 is fixedly installed on the barge, and the pump 2 is connected to the pump head 3 through a pipeline;
[0031] The boom 11 is provided with a guide rail 111 along its length direction, and the pump head 3 is slidably installed on the guide rail 111. The boom 11 is provided with a driving member 5 for driving the pump head 3 to slide on the guide rail 111; when the barge moves to the position where solidified soil needs to be blown and filled, the worker starts the driving member 5 to drive the pump head 3 to move to the predetermined position on the boom 11, and starts the crane 1 at the same time, and lowers the pump head 3 to the predetermined blowing and filling position through the hook 12. When the worker observes that the stress state of the wire rope of the hook 12 changes, it means that the pump head 3 is lowered to the bottom of the water and implanted. At this time, the worker starts to start the barge to drive the pump head 3 to move on the bottom of the water, and then blows the solidified soil slurry on the ship to the bottom of the water, thereby completing the fixation of the wind power pile.
[0032] The driving member 5 includes a roller 52 and a driving motor 51, the roller 52 is fixedly mounted on the hook 12, and the roller 52 is rollingly mounted on the guide rail 111; the driving motor 51 is fixedly mounted on the hook 12 and the output shaft of the driving motor 51 is connected to the rotating shaft of the roller 52 through a belt and pulley group; in the present embodiment, the belt and pulley group includes a first pulley, a second pulley and a belt, the first pulley is sleeved on the rotating shaft of the roller 52, the second pulley is sleeved on the output shaft of the driving motor 51, and the belt is simultaneously wound around the first pulley and the second pulley; the driving motor 51 can quickly move the hook 12, and then adjust the position of the pump head 3, so as to facilitate the pumping of the solidified soil slurry.
[0033] Reference Figure 3 The pump head 3 is provided with a fastening assembly 6 for compacting the solidified soil after pumping. The fastening assembly 6 comprises a box body 61 and a pair of pressing rollers 62. The box body 61 is fixed with the output end of the pump head 3, and the pump head 3 is connected to the inner cavity of the box body 61. The lower end of the box body 61 is open, and the two pressing rollers 62 are rotatably mounted at both ends of the box body 61 along the length direction. When the pump head 3 is lowered to the bottom of the water, the pressing rollers 62 are pressed by the gravity of the pump head 3 and the box body 61 to compact the solidified soil slurry that has been pumped out, thereby reducing the loss of solidified soil.
[0034] Reference Figure 3The rotating shaft of each pressing roller 62 is slidably installed on the inner wall of the box body 61 along the vertical direction. Each pressing roller 62 is hollow and a counterweight is arranged inside each pressing roller 62; the counterweight includes a counterweight block 63, which is sleeved on the rotating shaft of the pressing roller 62. When the pressing roller 62 is squeezed by a stone, the pressing roller 62 is lifted up to reduce the collision of the stone with the pressing roller 62. After the box body 61 passes the stone, the pressing roller 62 quickly returns to the bottom of the box body 61 under the action of the counterweight block 63, thereby continuing to compact and solidify the soil.
[0035] Reference Figure 3 The output end of the pump head 3 is located in the box body 61 and is provided with a plurality of buffer boxes 7. The pump head 3 is connected to each buffer box 7 through a pipeline. A discharge port is opened at the bottom of each buffer box 7, and the discharge port is used to release the solidified soil entering the buffer box 7 through the pump head 3.
[0036] The implementation principle of the device for blowing and filling solidified soil around offshore piles in the embodiment of the present application is as follows: first, the barge is driven to the sea area near the wind power pile, and then the worker adjusts the hook 12 and starts the crane 1 to lower the pump head 3 to the bottom of the water. When the worker observes that the stress of the wire rope of the hook 12 changes, the barge is started again to drag the pump head 3 and the box 61 around the wind power pile, so as to blow and fill the solidified soil;
[0037] After the solidified soil in the material pool 4 is transmitted to the pump head 3 through the pipeline, it is pumped out through multiple buffer boxes 7 to slow down the slurry discharge speed. At the same time, the pressure roller 62 in the box body 61 presses the solidified soil under the gravity of the counterweight block 63 and the box body 61 to reduce the loss of the solidified soil.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
