Description

Technical Field

[0001] This application relates to the field of offshore steel pipe pile foundation construction, and in particular to a high-pressure water jet type suction pipe. Background Technology

[0002] Offshore steel pipe pile foundations are a common type of foundation used in marine engineering, primarily to provide support for offshore structures such as offshore platforms, bridges, and wind turbine towers. During installation, the steel pipe pile foundation structures currently used on offshore platforms require driving the steel pipe piles into the seabed through mud, hard soil, or rock layers. To meet the installation requirements of the superstructure, it is often necessary to remove silt from the piles to a certain depth.

[0003] In existing technologies, steel pipe foundations are affected by the consolidation of seabed silt. Conventional sludge suction operations require divers to enter the pile and use water guns to flush the silt into mud before the mud can be extracted from the pile. This operation is costly, difficult, and carries significant safety risks. Furthermore, it is susceptible to sea conditions that may prevent divers from entering the water to perform the operation.

[0004] To address the above deficiencies, this application provides a high-pressure water jet type suction pipe that can perform dredging treatment inside steel pipe piles. Utility Model Content

[0027] Due to the consolidation of seabed silt, conventional sludge suction operations require divers to enter the pile and use water guns to flush the silt into mud before it can be extracted from the pile. This operation is costly, difficult, and carries significant safety risks. Furthermore, it is susceptible to sea conditions that may prevent divers from entering the water to perform the operation.

Figure 1 .at the same time, Figure 1 It also illustrates the working scenario of the embodiments of this application, such as Figure 1 The high-pressure water jet type suction pipe provided in this application embodiment is lowered into the steel pipe pile 140 by the construction vessel 110. Construction is carried out after the mud inlet is close to the seabed surface 130. Correspondingly, the mud outlet extends from the sea level 120. The equipment that needs to be placed on the water can be placed on the construction vessel 110.

[0031] like Figure 1 As shown, the suction pipe includes: a suction pipe body 200, a high-pressure air conveying device, and a high-pressure jetting device; wherein: The high-pressure jetting device includes several high-pressure nozzles 310, which are arranged around the mud inlet of the mud suction pipe body 200 and are used to flush the soil layer at the mud inlet. The high-pressure air delivery device includes an air compressor 410 and an air compressor duct 420, which is inserted into the sludge suction pipe body 200.

[0032] Specifically, the high-pressure jetting device flushes the soil layer inside the steel pipe pile, turning it from silt into highly fluid mud. The high-pressure air conveying device delivers compressed air to the suction pipe body 200, creating negative pressure within the suction pipe body 200 to pump out the mud, thus completing the mud suction operation.

[0033] This application provides a high-pressure water jet type sludge suction pipe, including a suction pipe body 200, a high-pressure air conveying device, and a high-pressure jetting device. The high-pressure jetting device flushes and removes silt from the soil layer inside the steel pipe pile, turning it into flowing sludge. An air compressor 410 operates within the suction pipe body 200 to create negative pressure for pumping water, drawing the sludge out of the suction pipe body 200. It has the following technical effects: The embodiments of this application can complete the suction of mud inside the pile without the need for divers to work underwater, and have the advantages of stable suction effect, high safety, and convenient and efficient use.

[0034] Figure 2 A schematic diagram of the structure of a high-pressure water jet type sludge suction pipe provided in this application embodiment. Figure 2 .

[0035] like Figure 2 As shown, the suction pipe includes a suction pipe body 200, a high-pressure jetting device, and a high-pressure air conveying device. Specifically, the silt on the soil layer is flushed by the high pressure of the high-pressure jetting device to form a highly fluid mud-water mixture. The high-pressure air conveying device creates a negative pressure in the suction pipe body 200 to pump water, thereby driving the mud to be extracted from the suction pipe body 200, thus completing the suction operation.

[0036] The specific structure of the high-pressure injection device is described below: Specifically, the high-pressure nozzles 310 are evenly distributed around the suction pipe body 200, and the angle between the spray direction of the high-pressure nozzles 310 and the axis of the suction pipe body 200 is set between 0° and 90°.

[0037] In one implementation, multiple high-pressure nozzles 310 are evenly distributed on different positions of the outer wall of the suction pipe body 200; multiple high-pressure nozzles 310 are also distributed in each position. The high-pressure nozzles 310 distributed in the same position have different spraying directions. The spraying directions of the high-pressure nozzles 310 are all set towards the direction of the mud inlet pipe, and the angle between the spraying direction and the axis of the suction pipe body 200 is set between 0° and 90°.

[0038] Furthermore, the high-pressure nozzles 310, which are set in the same direction, are evenly distributed according to their included angle within the range of 0° to 90°.

[0039] For example, if four high-pressure nozzles 310 are set in the same location, their included angles can be set to 0°, 30°, 60°, and 90° respectively.

[0040] Furthermore, the high-pressure jetting device also includes a water storage tank 320, which is fed by a water pump 330. The water pump 330 is connected to the water storage tank 320 through an inlet pipe, and the water storage tank 320 is connected to the high-pressure nozzle 310.

[0042] Specifically, the water tank 320 is designed in a ring shape. On the one hand, this ensures that the weight of the water tank is evenly distributed around the suction pipe body 200, maintaining the balance around the suction pipe body 200 and preventing one side from being too heavy and affecting the suction effect. On the other hand, the water tank 320 can also serve as a fixed support for the nozzle, making it convenient to fix the high-pressure nozzle 310 at different heights.

[0043] Specifically, a liquid level sensor is installed inside the water storage tank 320. The liquid level sensor is used to obtain the liquid level of the water storage tank 320 and to store water in the water storage tank 320 according to the liquid level.

[0044] According to the embodiment of the high-pressure nozzle 310 provided in this application, the high-pressure nozzle 310 can perform high-pressure flushing at different angles around the sludge suction port to achieve efficient sludge removal.

[0045] Specifically, the high-pressure jetting device includes a water storage tank 320 and several high-pressure nozzles 310. The water storage tank 320 is used to supply water to the high-pressure nozzles 310. The high-pressure nozzles 310 are installed around the mud inlet of the mud suction pipe body 200 and are used to flush the soil layer at the mud inlet.

[0046] The specific structure of the high-pressure air conveying device is described below: Specifically, the high-pressure air delivery device includes an air compressor 410 and an air compressor duct 420, which is connected to the side wall of the suction pipe body 200.

[0047] Specifically, the connection between the compressed air duct 420 and the sludge suction pipe body 200 is close to the sludge inlet of the sludge suction pipe body 200.

[0048] Specifically, high-pressure air is supplied to the sludge suction pipe body 200 by the air compressor 410, thereby creating a negative pressure in the sludge suction pipe body, drawing water upward and extracting the flowing sludge.

[0049] Furthermore, the suction pipe provided in this application embodiment also includes a lowering protection device, which includes a plurality of telescopic oil tops 510 fixed on the outer wall of the suction pipe body 200. The telescopic oil tops 510 can extend and retract radially along the suction pipe body 200, and the telescopic ends of the telescopic oil tops 510 are fixed with rollers 520.

[0050] Specifically, when the suction pipe body 200 is lowered, the telescopic hydraulic jack 510 can be used to press against the inner wall of the steel pipe pile, and the roller 520 can be used to slide down, avoiding collision with the steel pipe pile during lowering; and by using the telescopic hydraulic jack 510 in different directions to work together, the suction pipe body 200 can be tilted to complete the dredging operation at different positions at the bottom of the steel pipe pile.

[0051] Furthermore, the telescopic oil cap 510 is set on the same cross-section of the suction pipe body 200, and 4 to 8 caps are arranged around the suction pipe body 200 to ensure that the suction pipe body 200 can tilt in different directions.

[0052] Furthermore, a lifting lug 530 is fixed on the outer wall of the suction pipe body 200.

[0053] Specifically, there are two lifting lugs 530, which are set opposite each other on the outer wall of the suction pipe body 200; they are used to lift and lower the suction pipe body 200 during operation.

[0054] Specifically, an infrared sensor 630 and a pressure sensor 610 are also fixed on the outer wall of the suction pipe body 200, and the infrared sensor 630 and the pressure sensor 610 are fixed near the sludge inlet.

[0055] Specifically, by using the infrared sensor 630 to measure the distance, the distance from the suction pipe body 200 to the bottom or inner wall of the steel pipe pile can be obtained, which facilitates data observation and avoids impact.

[0056] Specifically, an underwater imaging device 620 is also fixed on the outer wall of the suction pipe body 200, and the underwater imaging device 620 is fixed near the mud inlet.

[0057] Furthermore, similarly, both the pressure sensor 610 and the underwater imaging device 620 are used to provide pressure data and image data, which facilitates the observation of underwater conditions by personnel on the surface of the water, making control easier and preventing contact with the bottom.

[0058] Specifically, the embodiments of this application also include a control module, which includes a controller. The controller is connected to the telescopic hydraulic jack 510, the infrared sensor 630, the pressure sensor 610, the imaging device, the valve of the high-pressure nozzle, and the valve of the water pump 330.

[0059] Specifically, the controller can be connected to the aforementioned devices via wired or wireless means, enabling remote or local control of these devices.

[0060] Specifically, the control module also includes a display screen and wireless transmission equipment to work with the controller to achieve control.

[0061] Specifically, the controller can control the water pump 330 to take in water by controlling the water level, control the tilt direction and angle of the suction pipe body 200 by controlling the telescopic oil top 510, and observe the underwater situation, so as to achieve effective control of the suction pipe and complete the suction operation inside the steel pipe pile more efficiently, conveniently and safely.

[0062] This application embodiment includes a suction pipe body 200, a high-pressure jetting device, a high-pressure air conveying device, a lowering protection device, and a control module. The high-pressure jetting device includes several high-pressure nozzles 310, which are arranged around the mud inlet of the suction pipe body 200 to flush the soil layer at the mud inlet. The high-pressure air conveying device includes an air compressor 410 and an air compressor duct 420, which extends into the suction pipe body 200.

This application embodiment has the following technical effects: The high-pressure jetting device includes a water storage tank 320 and several high-pressure nozzles 310. The water storage tank 320 is used to supply water to the high-pressure nozzles 310. The high-pressure nozzles 310 can perform high-pressure flushing at different angles around the sludge suction port to achieve efficient sludge removal.

[0063] The high-pressure air delivery device delivers high-pressure air into the sludge suction pipe body 200 through the air compressor 410, thereby creating a negative pressure inside the sludge suction pipe body, drawing water upwards, and extracting the flowing sludge.

[0064] When the suction pipe body 200 is lowered, it can be lowered through the lifting lug 530. The telescopic hydraulic jack 510 of the lowering protection device pushes against the inner wall of the steel pipe pile and slides down through the roller 520 to avoid collision with the steel pipe pile during lowering. Furthermore, by coordinating the output of the telescopic hydraulic jack 510 in different directions, the suction pipe body 200 can be tilted to complete the dredging operation at different positions at the bottom of the steel pipe pile.
