[0023] Embodiment

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: an easily removable road foundation pit steel sheet pile support structure, including a steel sheet pile body 1, a support assembly is arranged at the top of the steel sheet pile body 1, and a support assembly is arranged on the support assembly.

[0025] By setting up the support components without welding, the disassembly time of the support structure is greatly reduced, and at the same time, the installation efficiency of the support structure is improved. The support components include a support column 8, two support plates 9 and two threaded rods 10. The two support plates 9 are integrally formed at both ends of the support column 8 respectively. The two threaded rods 10 are respectively inserted into both ends of the support column 8 movably. Mounting seats 11 are installed at both ends of the support column 8. Rotating blocks 12 are rotatably connected to the sides of the two mounting seats 11 away from the support column 8. One end of the threaded rod 10 is rotatably connected to a top plate 13. The top of the support plate 9 is threadedly connected with a first limit bolt 14. One end of the first limit bolt 14 abuts against the outside of the rotating block 12. The rotating block 12 is threadedly connected to the outside of the threaded rod 10. By rotating the first limit bolt 14 in the reverse direction, one end of the first limit bolt 14 is disengaged from above the rotating block 12. At this time, the rotating block 12 can be rotated in the reverse direction by a tool. The rotating block 12 rotates on one side of the mounting seat 11. The rotating block 12 drives the threaded rod 10 to retract at one end of the support column 8, so that one end of the threaded rod 10 drives the top plate 13 to disengage from the outside of the top column 7, and then the support column 8 can be disassembled.

[0026] By setting up the support components, the top column 7 can be supported and it is convenient to disassemble at the same time. The support components include a connecting block 3, a limit plate 4 and a support plate 5. An installation groove 2 is opened at the top of the steel sheet pile body 1. The connecting block 3 is inserted into the interior of the installation groove 2. The limit plate 4 is fixedly connected to one side of the connecting block 3. The support plate 5 is fixedly connected to the other side of the connecting block 3. The top column 7 is placed on the support plate 5. By rotating the second limit bolt 16 in the reverse direction, one end of the second limit bolt 16 is disengaged from the bottom of the top column 7, then the top column 7 is disassembled, and then the support plate 5 is removed from the steel sheet pile body 1, so that the connecting block 3 is disengaged from the interior of the installation groove 2, and the disassembly of the support structure of the steel sheet pile body 1 can be completed.

[0027] A convex plate 6 is arranged at one end of the support plate 5. The convex plate 6 abuts against the outside of the top column 7. The top column 7 can be limited by the convex plate 6. The support plate 9 is placed on the top of the top column 7. The top plate 13 abuts against one side of the top column 7. The support plate 9 can support the support column 8 to prevent the support column 8 from falling. The bottom of the support plate 5 is threadedly connected with a second limit bolt 16. One end of the second limit bolt 16 is connected to the bottom of the top column 7. The second limit bolt 16 can fix the top column 7 to ensure the stability of the fixation of the top column 7. Connecting grooves 15 are arranged at both ends of the steel sheet pile body 1. Adjacent two steel sheet pile bodies 1 are connected through the connecting grooves 15. Through the arrangement of the connecting grooves 15, the installation stability and integrity of the steel sheet pile body 1 can be enhanced.

[0028] The working principle or structural principle is that when it is necessary to dismantle the support of the steel sheet pile body 1, the first limiting bolt 14 is rotated in the opposite direction, and one end of the first limiting bolt 14 is disengaged from the top of the rotating block 12. At this time, the rotating block 12 can be rotated in the opposite direction by a tool, and the rotating block 12 is rotated on one side of the mounting seat 11, and the rotating block 12 drives the threaded rod 10 to retract at one end of the support column 8, so that one end of the threaded rod 10 drives the top plate 13 to disengage from the outside of the top column 7. When the top plate 13 is separated from the top column 7, the support column 8 is supported by the support plate 9. At this time, the support column 8 can be disassembled, and then the second limiting bolt 16 is rotated in the opposite direction, so that one end of the second limiting bolt 16 is disengaged from the bottom of the top column 7, and then the top column 7 is disassembled, and then the support plate 5 is removed from the steel sheet pile body 1, so that the connecting block 3 is separated from the inside of the mounting groove 2, and the disassembly of the supporting structure of the steel sheet pile body 1 can be completed. Without welding, the disassembly time of the supporting structure is greatly reduced, and the installation efficiency of the supporting structure is improved.
