Description

Technical Field

[0001] This utility model belongs to the technical field of engineering construction equipment, and in particular relates to a trench-type steel sheet pile retaining support component. Background Technology

[0002] Steel sheet piles are commonly used in retaining wall construction. They feature interlocking mechanisms at their edges, which can be freely combined to form a continuous and tightly constructed steel structure for retaining walls or water barriers. Essentially, they are long, narrow steel sections with cross-sections including straight plates, channel shapes, and Z-shapes, available in various sizes and interlocking configurations. They are high-strength, easily driven into hard soil layers, and can be installed in deep water. When necessary, they can be reinforced with diagonal supports to form a cage-like structure, making them widely applicable.

[0003] For underground installation of municipal stormwater and sewage pipes, trenches need to be excavated. Before excavation, steel sheet piles must be driven into the soil as retaining walls to form support. Then, the trench is excavated between the two retaining walls to prevent loose soil from causing the soil on the sides of the trench to collapse and flow back into the trench. Specifically, a small portion of the surface soil is excavated first to expose a section of the upper side of the steel sheet piles. Then, the walers and internal supports are installed. After the supports are installed, the excavation continues until the required depth for pipe installation is reached.

[0004] Sheet piles used in trenches require internal supports to prevent deformation of the sheet pile retaining structure caused by the shrinkage and compression of the soil on both sides after the trench soil is excavated. The existing supports are channel steel structures, which are cumbersome to install and do not provide adequate support. As a result, the retaining structure formed by the sheet piles still deforms slightly, causing great inconvenience for later dismantling. Utility Model Content

[0005] The purpose of this utility model is to provide a grooved steel sheet pile retaining support component, which can adjust the support length according to the spacing between steel sheet pile supports, improve the support compactness, and reduce the deformation problem of steel sheet pile supports caused by soil shrinkage.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A grooved steel sheet pile retaining support component is located between two steel sheet pile retaining structures, including a main channel steel and a secondary channel steel. The main channel steel and the secondary channel steel have a U-shaped cross section and have a slotted side.

[0008] The main channel steel and the secondary channel steel have a detachable structure at their joint ends. The free end of the main channel steel serves as one end of the support member and is in contact with the support. The free end of the secondary channel steel is equipped with an adjustable telescopic member. One end of the telescopic member is telescopically adjustable with the end of the secondary channel steel, and the other end has a support plate, which serves as the other end of the support member and is in contact with the support.

[0009] Furthermore, the telescopic component is a column, with a column sleeve provided at the free end of the auxiliary channel steel. One end of the column is fixed with a support plate, and the other end extends to the column sleeve and telescopically cooperates with the column sleeve. The column is provided with a limit component.

[0010] The column has threads on its sidewall, and the limiting member is a threaded sleeve that fits onto the column with a threaded connection. A collar is fixed to the free end of the column, and the bottom of the secondary channel steel has rows of round holes.

[0011] Furthermore, there is an I-beam between the contact side of the support member and the contact side of the sheet pile, and hooks are provided on the upper side of the contact side of the support plate and the main channel steel for hooking onto the edge of the I-beam.

[0012] Furthermore, the main channel steel and the secondary channel steel have webs arranged in the corresponding inner channels.

[0013] Furthermore, the main channel steel and the auxiliary channel steel have flange plates at their mating ends and through holes for fixing with bolts.

[0014] This invention offers the following advantages: The supporting component of this invention features a uniform secondary channel steel, while the main channel steel comes in various length specifications. The length requirement of the main channel steel is first determined based on the width of the groove. Then, the main channel steel and secondary channel steel are joined together, resulting in a supporting component whose length approximately matches the width between the grooves. To improve the supporting effect, the free end of the secondary channel steel also has a telescopic component. By adjusting the telescopic component, the overall length of the secondary channel steel can be slightly increased, ensuring an interference fit on the contact side of the supporting component's end, thus improving the support's tightness.

[0017] Figure 2 : Schematic diagram of the installation structure of this utility model in conjunction with I-beams.

[0018] Figure 3 : Schematic diagram of the column disassembly structure of this utility model.

[0019] The components represented by each number in the attached diagram are listed below: main channel steel 1, secondary channel steel 2, support plate 4, column 3, column sleeve 21, threaded sleeve 31, collar 32, round hole 22, I-beam 5, hook 41, web plate 11, and flange plate 12. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-2 As shown: A grooved steel sheet pile retaining support component is located between two steel sheet pile retaining structures, including a main channel steel 1 and a secondary channel steel 2. The main channel steel 1 and the secondary channel steel 2 have a U-shaped cross section and have a slotted side.

[0022] The main channel steel 1 and the secondary channel steel 2 have a detachable structure at their joint ends. The free end of the main channel steel 1 serves as one end of the support member and is in contact with the support. The free end of the secondary channel steel 2 is equipped with an adjustable telescopic member. One end of the telescopic member is telescopically adjustable with the end of the secondary channel steel 2, and the other end has a support plate 4, which serves as the other end of the support member and is in contact with the support.

[0023] Before excavating trenches for municipal sewage pipelines, the trench needs to be dug according to the diameter of the culvert. The width of the trench is set according to the diameter of the culvert, and then steel sheet piles are driven in. Because the width of the trench is not uniform, existing support components cannot fully accommodate the steel sheet piles on both sides. The support component of this invention uses a uniform secondary channel steel, while the main channel steel has various length specifications. The length requirement of the main channel steel is first determined according to the width of the trench. Then, the main channel steel and the secondary channel steel are joined together, and the length of the resulting support component is approximately adapted to the width between the trenches. To improve the support effect, the free end of the secondary channel steel also has an expansion joint. By adjusting the expansion joint, the overall length of the secondary channel steel can be slightly increased, making the contact side of the support component's end an interference fit, thus improving the support's tightness.

[0024] like Figure 3 As shown: The telescopic component is a column 3. A column sleeve 21 is provided at the free end of the secondary channel steel 2. One end of the column 3 is fixed with a support plate 4, and the other end extends to the column sleeve 21 and telescopically cooperates with the column sleeve. The column 3 is provided with a limiting component. The support length of the secondary channel steel is adjusted by telescopic column. After the length is adjusted, the column is fixed by limiting component.

[0025] The side wall of column 3 has threads, and the limiting component is a threaded sleeve 31, which is fitted onto column 3 and threadedly engaged. The support component serves as a horizontal support and is limited to extending the length of the secondary channel steel. After adjusting the length, rotating the threaded sleeve forms a limit to prevent the column from retracting.

[0026] A collar 32 is fixed to the free end of column 3, and a row of round holes 22 are arranged at the bottom of the secondary channel steel 2. When extending the column to increase the overall support length of the secondary channel steel, a pry bar can be passed through the collar and positioned obliquely in the round holes. Then, the pry bar can be moved to push the column laterally, similar to a lever action, so that the support plate at the other end of the column compresses the steel sheet pile's contact side, increasing the compactness.

[0027] like Figure 2As shown: An I-beam 5 is also present between the contact side of the support member and the contact side of the sheet pile. Hooks 41 are provided on the upper sides of the contact sides of the support plate 4 and the main channel steel 1 for hooking onto the edge of the I-beam 5. The I-beam serves as the waler for facade support, providing facade support for all individual sheet piles. The support member is installed on the I-beam via the hook structure, making assembly and disassembly more convenient.

[0028] like Figure 3 As shown: The main channel steel 1 and the auxiliary channel steel 2 have web plates 11 arranged in the corresponding inner channels to improve the support strength. The mating ends of the main channel steel 1 and the auxiliary channel steel 2 have flange plates 12 with through holes for fixing with bolts.

[0029] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
