Description

Technical Field

[0001] This application relates to the field of foundation pit support technology, and in particular to a steel sheet pile support structure. Background Technology

[0002] Sheet pile support is a commonly used method for foundation pit support. A typical sheet pile support structure includes sheet piles, walers, and steel supports. The steel supports are usually fixed to the walers by bolts or welding, making assembly and disassembly of the steel supports inconvenient. To address this, the inventors have proposed a new sheet pile support structure. Utility Model Content

[0003] This application provides a steel sheet pile support structure that facilitates the assembly and disassembly of steel supports.

[0004] The technical solution of this application is as follows:

[0005] This application provides a sheet pile support structure, including sheet piles, walers, and steel supports. A positioning rod is inserted into the inside of the steel support, and a movable sleeve is screwed onto the outside of the steel support. A lever on the positioning rod extends out of the steel support and slides into the inner wall of the movable sleeve. The movable sleeve can drive the positioning rod to be inserted into the positioning hole on the waler.

[0006] By using the technical solution of this application, the movable sleeve is screwed toward the waler, which can push the positioning rod into the positioning hole, thereby connecting the steel support between the corresponding walers, which facilitates the assembly and disassembly of the steel support.

[0007] In some implementations, a sleeve for inserting a positioning rod is welded into the positioning hole.

[0008] In some implementations, the positioning rod and the steel support are arranged coaxially.

[0009] In some implementations, the outer diameter of the positioning rod is equal to the inner diameter of the steel support.

[0010] In some implementations, the steel support is provided with a groove for the extension of the lever.

[0011] In some implementations, the chute is parallel to the axis of the steel support.

[0012] In some implementations, the lever and the positioning lever are arranged perpendicularly.

[0013] In some implementations, the lever is arranged radially along the steel support.

[0014] In some implementations, the inner wall of the movable sleeve is provided with a slot for engaging the lever.

[0015] In some implementations, the slot is constructed as a circle arranged coaxially with the movable sleeve. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0024] In related technologies, sheet pile support is a commonly used method for foundation pit support. Sheet pile support structures typically include sheet piles, walers, and steel supports. The steel supports and walers are usually fixed by bolting or welding, which makes the disassembly and assembly of the steel supports inconvenient.

[0025] This embodiment provides a steel sheet pile support structure that facilitates the assembly and disassembly of steel supports.

[0026] Please see Figures 1-2 In this embodiment, a sheet pile support structure includes sheet piles 10, walers 20, and steel supports 30. A positioning rod 31 is inserted inside the steel support 30, and a movable sleeve 33 is screwed onto the outside of the steel support 30. A lever 32 on the positioning rod 31 extends out of the steel support 30 and slides into contact with the inner wall of the movable sleeve 33. The movable sleeve 33 can drive the positioning rod 31 to be inserted into the positioning hole on the waler 20.

[0027] By using the technical solution of this embodiment, the movable sleeve 33 is screwed toward the waler 20, and the positioning rod 31 can be pushed into the positioning hole, thereby connecting the steel support 30 between the corresponding walers 20, which facilitates the assembly and disassembly of the steel support 30.

[0028] In this embodiment, the walers 20 are welded to the inner wall of the sheet pile 10, and the steel support 30 is set between the corresponding two walers 20. The corresponding two walers 20 are arranged in parallel. Positioning holes are opened on the walers 20, and sleeves 21 are welded inside the positioning holes. The sleeves 21 are used to insert the positioning rods 31 on the steel support 30. The sleeves 21 can compensate for the structural defects caused by the openings in the walers 20 and can ensure the structural strength.

[0029] In this embodiment, the steel support 30 is constructed as a hollow cylindrical tube. The positioning rod 31 is inserted into the inner cavity of the steel support 30. The outer diameter of the positioning rod 31 is equal to the inner diameter of the steel support 30. The positioning rod 31 can slide along the axial direction of the steel support 30. A sliding groove 35 is provided on the side wall of the steel support 30. The sliding groove 35 is arranged parallel to the axis of the steel support 30. A lever 32 is welded to the outer wall of the positioning rod 31. The lever 32 is arranged perpendicular to the positioning rod 31 and is arranged radially along the steel support 30. The lever 32 is slidably engaged inside the sliding groove 35. By utilizing the sliding engagement of the lever 32 and the sliding groove 35, the positioning rod 31 is only allowed to move along the axial direction of the steel support 30, preventing the positioning rod 31 from rotating.

[0030] In addition, the movable sleeve 33 is screwed onto the outside of the steel support 30. A groove 34 is provided on the inner wall of the movable sleeve 33, and the groove 34 is constructed to be circular and coaxially arranged with the movable sleeve 33. The outer end of the lever 32 extends out of the steel support 30 and is engaged in the groove 34. When the movable sleeve 33 rotates on the steel support 30, it pushes the positioning rod 31 to move inside the steel support 30 and can insert the positioning rod 31 into the sleeve 21, thereby connecting the steel support 30 as a whole between the two corresponding walers 20.

[0031] It should be noted that, in order to further improve the ease of disassembly and assembly of the steel support 30, overlapping plates 36 are provided at both ends of the steel support 30. The overlapping plates 36 can overlap the walers 20, so that the steel support 30 can be supported on the two walers 20.

[0032] It should be understood that the plug-in fixing method of the steel support 30 and the waler 20 in this embodiment facilitates the assembly and disassembly of the steel support 30 compared to the traditional bolting and welding fixing methods.

[0033] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
