Description

Technical Field

[0001] This utility model relates to the field of underwater construction technology, specifically a steel sheet pile fixing bracket in an underwater environment. Background Technology

[0002] In the construction of water-related infrastructure such as water conservancy projects, port terminals, cross-sea bridges, and municipal deep foundation pits, steel sheet piles are widely used as an efficient and economical retaining structure due to their excellent load-bearing capacity and water-stopping effect. However, construction conditions in aquatic environments are often quite complex. Dynamic loads such as water flow, waves, and tides act continuously, and the underwater foundation may contain weak soil layers. These factors all pose challenges to the accurate positioning and verticality control of steel sheet piles.

[0003] Currently, temporary supports are typically required during sheet pile construction to ensure driving accuracy. However, in practical applications, it has been found that some existing support structures perform poorly under complex hydrological conditions. For example, some supports have limited overall rigidity and are prone to deformation when subjected to water flow impact or pile driving vibration, directly affecting the positioning accuracy of the sheet piles; some supports have inadequately designed connection nodes, which may loosen during construction, affecting the overall stability of the structure. The stability and reliability of the support structure are particularly important in construction phases requiring frequent disassembly and reassembly. Utility Model Content

[0004] The present invention aims to solve the above problems, thereby providing a steel sheet pile fixing bracket that can provide stable support in a water environment during the support stage.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is: A sheet pile fixing bracket in an aquatic environment includes at least two parallel and spaced-apart support groups. Each support group includes two opposing columns on both sides. At least two support groups are arranged opposite each other along the height direction on the column above the water surface. A guide beam is supported on the support groups of the same height on the same side. The guide beams on both sides together form a guide frame for clamping and guiding the sheet pile.

[0006] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: The lower part of the column is fixed in the water, while the support assembly and guide beam are located above the water surface. Through the coordinated cooperation of the support assembly and the guide frame, a stable spatial force system is constructed. The columns in the support assembly form a stable support foundation through their arrangement, and the guide frame provides a reliable guiding function through its structural form. The support assembly and the guide frame are effectively connected through the support assembly to form an overall force-bearing structure. This structural arrangement can distribute and transfer construction loads, improve overall rigidity, help reduce support deformation, and maintain the accuracy of sheet pile driving.

[0007] As a preferred embodiment, a further technical solution of this utility model is: Furthermore, the columns are groove-shaped and the openings of the columns in the same group are opposite to each other, which allows the strong axis of each column to better resist the load from the outside of the guide frame, thereby improving the overall lateral stability of the support group.

[0008] Furthermore, a limiting plate is provided between the tops of the columns in the same group. The bottom sides of the limiting plate are provided with groove-shaped engaging parts. The engaging parts are engaged on the top of the columns. The setting of the limiting plate can constrain the relative displacement of the columns, maintain the geometric shape of the support group, and prevent the spacing of the columns from changing under the action of water flow and vibration.

[0009] Furthermore, the support assembly includes a support block fixed to the column, with one end of the support block extending towards the column side of the same assembly. A support plate is provided on the surface of the guide beam near the adjacent column, sitting on the support block. The support block and the support plate are welded and fixed. Through the cooperation of the support block and the support plate, the guide beam is firmly fixed to the column, which not only ensures the effective transfer of load, but also prevents the guide beam from shifting or loosening during construction.

[0010] Furthermore, each support group has at least two support blocks spaced apart from top to bottom, with the number of support plates corresponding to the number of support blocks. The support blocks are arranged in an alternating manner to provide the guide beam with multiple support points, improve its stress state, increase its bending stiffness, and ensure the stability of the guiding function.

[0011] Furthermore, a guide channel is formed between the guide beams on both sides for the steel sheet piles to pass through. The guide frame adopts a double beam and multi-layer parallel arrangement to form a guide channel with accurate dimensions, providing stable constraints for the steel sheet piles and ensuring positioning accuracy during the driving process.

Detailed Implementation

[0013] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] A sheet pile fixing bracket in an aquatic environment includes at least two parallel and spaced-apart support groups. Each support group includes two opposing columns 1 on both sides. At least two support groups are arranged opposite each other along the height direction on the column 1 above the water surface. A guide beam 2 is supported on the support groups of the same height on the same side. The guide beams 2 on both sides together form a guide frame for clamping and guiding the sheet pile 5. The multi-layered guide beams 2 ensure the stability of the sheet pile 5.

[0015] Furthermore, the column 1 is groove-shaped and the openings of the columns 1 in the same group are opposite to each other. The column 1 is made of steel groove, which enables the strong axis of each column 1 to better resist the load from the outside of the guide frame, thereby improving the overall lateral stability of the support group.

[0016] Furthermore, a limiting plate 3 is provided between the tops of the columns 1 in the same group. The bottom sides of the limiting plate 3 are respectively provided with groove-shaped engaging parts. The engaging parts are engaged on the top of the column 1. The two engaging parts are respectively engaged on the top of the opposite side of the limiting plate 3, and the engaging parts are limited by the two side walls of the opening of the column 1. The setting of the limiting plate 3 can constrain the relative displacement of the column 1, maintain the geometric shape of the support group, and prevent the spacing of the column 1 from changing under the action of water flow and vibration.

[0017] Furthermore, the support assembly includes a support block 4 fixed on the column 1. One end of the support block 4 extends toward the column 1 in the same assembly. A support plate is provided on the surface of the guide beam 2 near the adjacent column 1, which sits on the support block 4. The support block 4 and the support plate are welded and fixed. Through the cooperation of the support block 4 and the support plate, the guide beam 2 is firmly fixed to the column 1, which not only ensures the effective transfer of load, but also prevents the guide beam 2 from shifting or loosening during construction.

[0018] Furthermore, at least two support blocks 4 are arranged at intervals from top to bottom in each support group, and the number of support plates corresponds to the number of support blocks 4. In this embodiment, the support blocks 4 are arranged in two layers. The guide beam 2 is made of channel steel or I-beam. The flange of the material itself serves as the support plate for the two layers. The support blocks 4 are arranged in an alternating manner to provide the guide beam 2 with multiple support points, improve its stress state, increase its bending stiffness, and ensure the stability of the guiding function.

[0019] Furthermore, a guide channel is formed between the guide beams 2 on both sides for the steel sheet pile 5 to pass through. The guide frame adopts a double beam and multi-layer parallel arrangement to form a guide channel with accurate dimensions, providing stable constraints for the steel sheet pile 5 and ensuring positioning accuracy during the driving process.

[0020] During construction, at least two rows of support columns 1 are first driven into the underwater foundation, ensuring the lower part of the columns 1 is firmly anchored to the bottom. At this point, the openings of the columns 1 in the same group are facing away from each other, effectively resisting lateral loads such as water flow impact by utilizing the strong axial direction of the channel steel. Then, the superstructure is installed above the water surface. The support plates at the ends of the guide beams 2 are accurately placed on the various levels of support blocks 4 already welded to the columns 1. The support blocks 4, arranged vertically and vertically, form multi-point support with the support plates, and are firmly fixed to the support blocks 4 and support plates by welding, providing stable support for the guide beams 2 and preventing loosening of the connection due to pile driving vibration. Next... Limiting plates 3 are installed on the top of the column 1 in the same group to constrain the relative displacement of the top of the column 1 and prevent the spacing of the supports from changing under the action of water flow and vibration. Finally, the guide channel formed by the multi-layer parallel guide beams 2 on both sides provides precise positioning for the steel sheet pile 5. During the pile driving process, the entire support effectively disperses the construction load and suppresses structural deformation through the spatial force system formed by the column 1, the supporting components and the limiting plates 3. It overcomes the defects of insufficient rigidity and easy loosening of nodes of traditional supports, and ensures that the steel sheet pile 5 is always driven vertically along the predetermined trajectory. After the construction of this section is completed, the welding point can be cut off and the support can be dismantled and reused.

[0021] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
