Description

Technical Field

[0001] This application belongs to the field of underwater engineering technology, specifically relating to an underwater grouting structure based on a suction bucket. Background Technology

[0002] Suction bucket foundations, as a novel type of foundation structure, have been widely used in marine engineering fields such as offshore wind power and offshore oil platforms. They offer advantages such as rapid construction, minimal environmental impact, and reusability. By applying negative pressure inside the bucket, it sinks into the seabed, providing stable support for the superstructure. Underwater grouting aims to fill the gap between the suction bucket and the seabed, improving the foundation's load-bearing capacity and stability while preventing seawater erosion of the bucket and foundation soil. Therefore, underwater grouting pipeline structures are required for suction bucket foundations.

[0003] In most existing suction tanks, grouting is achieved by connecting the grouting pipe and overflow pipe at the top to the equipment pipelines on the construction vessel's deck. However, in actual operation, these pipelines are prone to displacement, especially when the pipelines are full, and problems such as pipeline bends leading to blockages may even occur.

[0004] Therefore, there is an urgent need to propose an underwater grouting structure based on a suction bucket to ensure the smooth progress of grouting operations. Utility Model Content

[0011] Furthermore, in the aforementioned underwater grouting structure based on a suction bucket, the cross-section of the support plate is trapezoidal, a plurality of grouting pipe positioning rings are sequentially arranged on the first inclined surface of the support plate, and a plurality of overflow pipe positioning rings are sequentially arranged on the second inclined surface of the support plate.

[0012] Furthermore, in the above-mentioned underwater grouting structure based on a suction bucket, the first inclined surface is disposed opposite to the grouting port; the second inclined surface is disposed opposite to the overflow port.

[0013] Furthermore, in the above-mentioned underwater grouting structure based on a suction bucket, the plurality of grouting pipe positioning rings are arranged at equal intervals; and / or, the plurality of overflow pipe positioning rings are arranged at equal intervals.

[0020] This application installs a fixing component on the top plate of the suction tank, with multiple grouting pipe positioning rings fixed to the outside of the grouting pipe and multiple overflow pipe positioning rings fixed to the outside of the overflow pipe.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] like Figures 1 to 6As shown in one embodiment of this application, an underwater grouting structure based on a suction bucket includes: a fixing component 2 and a suction bucket 301 having a grouting port and an overflow port; the fixing component 2 includes: a plurality of grouting pipe positioning rings 203, a plurality of overflow pipe positioning rings 205 and a support plate 202, the support plate 202 being disposed on the top plate 1 of the suction bucket 301, and the plurality of grouting pipe positioning rings 203 and the plurality of overflow pipe positioning rings 205 being disposed on the support plate 202; the grouting pipe 9 is connected to the grouting port through the grouting pipe positioning rings 203, and the overflow pipe 11 is connected to the overflow port through the overflow pipe positioning rings 205.

[0032] In this embodiment, by setting a fixing component 2 on the top plate 1 of the suction tank 301, multiple grouting pipe positioning rings 203 are fixed to the outside of the grouting pipe 9, and multiple overflow pipe positioning rings 205 are fixed to the outside of the overflow pipe 11. This ensures that after the grouting pipe 9 and the overflow pipe 11 are connected to the suction tank 301, one end of the grouting pipe 9 and the overflow pipe 11 can be effectively fixed and guided, preventing the grouting pipe 9 and the overflow pipe 11 from displacing and falling off after being filled and being washed away by seawater, thus ensuring the smooth progress of the grouting operation.

[0033] Optionally, the grouting pipe positioning ring 203 and / or the overflow pipe positioning ring 205 are open structures; when the grouting pipe positioning ring 203 is an open structure, it is equipped with a first locking bolt 204; when the overflow positioning ring is an open structure, it is equipped with a second locking bolt 206.

[0034] In this embodiment, both the grouting pipe positioning ring 203 and the overflow pipe positioning ring 205 are open structures. The grouting pipe positioning ring 203 is equipped with a first locking bolt 204, and the overflow pipe positioning ring is equipped with a second locking bolt 206, so as to adjust the size of the positioning ring according to the size of the grouting pipe 9 and the overflow pipe 11, thereby improving the applicability of the equipment.

[0035] Specifically, the support plate 202 has a trapezoidal cross-section, and a plurality of grouting pipe positioning rings 203 are sequentially arranged on the first inclined surface of the support plate 202, and a plurality of overflow pipe positioning rings 205 are sequentially arranged on the second inclined surface of the support plate 202. By setting the first and second inclined surfaces, the grouting pipes 9 and 11 are guided, which is beneficial to fixing the positions of the grouting pipes 9 and 11.

[0036] Specifically, the first inclined surface is positioned opposite to the grouting port; the second inclined surface is positioned opposite to the overflow port. This arrangement facilitates the nearby fixing of the grouting pipe 9 and the overflow pipe 11, preventing them from intersecting.

[0037] Optionally, a plurality of the grouting pipe positioning rings 203 are arranged at equal intervals; and / or, a plurality of the overflow pipe positioning rings 205 are arranged at equal intervals.

[0038] In this embodiment, the number of grouting pipe positioning rings 203 and the number of overflow pipe positioning rings 205 are each set to three. Those skilled in the art will be motivated to make adaptive adjustments to the number of grouting pipe positioning rings 203 and overflow pipe positioning rings 205 according to actual needs. Setting the three grouting pipe positioning rings 203 and the three overflow pipe positioning rings 205 at equal intervals is beneficial to the uniform stress on the grouting pipe positioning rings 203 and overflow pipe positioning rings 205.

[0039] Optionally, multiple grouting pipe positioning rings 203 and / or multiple overflow pipe positioning rings 205 are distributed at the ends of the support plate 202 away from the suction bucket 301, so that the connection between the grouting pipe 9, the overflow pipe 11 and the suction bucket 301 has a certain amount of room for movement, avoiding small-angle bending of the grouting pipe 9 and the overflow pipe 11, which would cause poor flow of grout inside the pipe.

[0040] Specifically, the support plate 202 is connected to the suction barrel 301 via a connecting seat 207. Specifically, the top plate 1 of the suction barrel 301 and the connecting seat 207 are provided with corresponding mounting holes 201. The connecting seat 207 is connected to the top plate 1 via a mounting bolt 208 to ensure that the support plate 202 is stably set on the suction barrel 301.

[0041] Optionally, the grouting port is provided with a grout inlet pipe 303, and the splicing base plate 4 of the grout inlet pipe 303 is connected to the splicing top plate 7 of the grouting pipe 9. Specifically, the splicing base plate 4 and the splicing top plate 7 are provided with corresponding splicing holes 6. The splicing top plate 7 and the splicing base plate 4 are connected by splicing bolts 8 to ensure the stability of the connection between the grout inlet pipe 303 and the grouting pipe 9. At the same time, it can also adapt to the connection of grout inlet pipes 303 and grouting pipes 9 with different pipe diameters, thereby improving the adaptability of the grouting structure.

[0042] Optionally, the overflow port is provided with a slurry outlet pipe 302, and the slurry outlet pipe 302 is provided with a sleeve pipe 10 to be sleeved with the overflow pipe 11.

[0043] In this embodiment, construction workers can connect the grouting pipe 9 to the grout inlet pipe 303 and the overflow pipe 11 to the grout outlet pipe 302 on the deck of the construction vessel. This makes it easier for subsequent operations after the suction tank 301 is placed in the water. The overflow pipe 11 can transfer the overflow observation procedure from underwater to above water, making it easier for construction workers to observe and control the progress of the operation, thereby improving practicality.

[0044] Specifically, the splicing chassis 4 is provided with a sealing ring 5 inside to ensure the sealing of the connection between the grout inlet pipe 303 and the grouting pipe 9 and to prevent grout leakage.

[0045] Optionally, the top plate 1 of the suction tank 301 is provided with a handle 12 to facilitate manual adjustment of the position of the suction tank 301.

[0046] In this embodiment, a fixing component 2 is set on the top plate 1 of the suction tank 301. Multiple grouting pipe positioning rings 203 are fixed to the outside of the grouting pipe 9, and multiple overflow pipe positioning rings 205 are fixed to the outside of the overflow pipe 11. This ensures that after the grouting pipe 9 and the overflow pipe 11 are connected to the suction tank 301, one end of the grouting pipe 9 and the overflow pipe 11 can be effectively fixed and guided, preventing the grouting pipe 9 and the overflow pipe 11 from displacing and falling off after being filled and being washed away by seawater, thus ensuring the smooth progress of the grouting operation.

[0047] Example 2

[0048] The difference between this embodiment and Embodiment 1 is that the fixing components in this embodiment include: multiple grouting pipe positioning rings 203, multiple overflow pipe positioning rings 205, grouting pipe support plates and overflow pipe support plates. The grouting pipe support plates and the overflow pipe support plates are both disposed on the top plate 1 of the suction bucket 301. The multiple grouting pipe positioning rings 203 are disposed on the grouting pipe support plates, and the multiple overflow pipe positioning rings 205 are disposed on the overflow pipe support plates.

[0049] In this embodiment, multiple grouting pipe positioning rings 203 are set on the grouting pipe support plate, and multiple overflow pipe positioning rings 205 are set on the overflow pipe support plate. That is, the support plate in Embodiment 1 is set separately to more flexibly deal with the situation where the distance between the grouting port and the overflow port is too far, resulting in limited fixation of the grouting pipe and the overflow pipe.
