The push rod 9 is slidably connected to the inner wall of the guide groove 10 along the vertical direction. The bottom end of the push rod 9 is provided with a slope surface. The top cross-section of the push rod 9 is L-shaped, and the top side of the push rod 9 is fixedly connected to the limiting block 31.

[0037] The connecting mechanism 3 also includes a first docking rod 11, a second docking rod 12 and a third docking rod 13 installed at the bottom of the steel plate body 1. One end of the second docking rod 12 and both ends of the third docking rod 13 are provided with docking grooves 15 that can be docked with the adjacent first docking rod 11, second docking rod 12 and third docking rod 13. The bottom surfaces of the first docking rod 11, the second docking rod 12 and the third docking rod 13 are all conical in design, and the steel plate body 1 is provided with a connecting piece 16 for connecting the first docking rod 11, the second docking rod 12 and the third docking rod 13.

[0038] The connecting member 16 includes a plug-in block 17 fixedly mounted on the first docking rod 11, the second docking rod 12 and the third docking rod 13. The bottom of the steel plate body 1 is provided with a plug-in slot 18 that can be plugged into the plug-in block 17. Two sets of fixed rods 19 are fixedly connected to the steel plate body 1. The fixed rods 19 are provided with a control member 20 for controlling the connection state between the plug-in block 17 and the plug-in slot 18.

[0039] The control member 20 includes a beveled tooth block 22 mounted on the fixed rod 19. A sliding groove 23 is provided on the fixed rod 19. The beveled tooth block 22 is slidably connected to the inner wall of the sliding groove 23. A clamping groove 24 that can be plugged into the beveled tooth block 22 is provided on the side of the plug-in block 17.

A driving member 26 for controlling the plug-in state of the beveled tooth block 22 from the top is provided on the fixed rod 19.

[0040] The driving member 26 includes a steel wire rope 28 fixedly mounted on the bevel gear block 22. A driving groove 29 is provided at the top of the fixed rod 19. A driving block 30 is slidably connected in the driving groove 29. The end of the steel wire rope 28 away from the bevel gear block 22 is fixedly connected to the bottom of the steel wire rope 28. The steel wire rope 28 passes through the fixed rod 19 and is slidably connected to the inner wall of the fixed rod 19.

[0041] In this embodiment, the first docking rod 11 is installed on the bottom of the first group of steel plate bodies 1 to be installed, the third docking rod 13 is installed on the bottom of the last installed steel plate body 1, and the second docking rod 12 is installed on the remaining middle steel plate bodies 1. During installation, the plug-in block 17 is plugged into the plug-in slot 18 so that the bevel tooth block 22 is inserted into the clamping slot 24 to complete the fixation. The end of the first group of steel plate bodies 1 away from the first docking rod 11 is grabbed through the mechanical wall and inserted vertically downward to the set position. The sliding rod 4 is inserted into the lock buckle 2 on both sides of the steel plate body 1, so that the lock buckle 2 is in a state of being supported by the sliding rod 4 during the insertion process, and the same When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked. When the locking cam 2 is in the locked position, the locking cam 2 and the sliding rod 4 are locked.

[0042] The mechanical arm is used to grab one end of the adjacent steel plate body 1 so that the docking groove 15 is fitted with the outer wall of the lock buckle 2. At the same time, the lock buckle 2 on one side of the steel plate body 1 is docked with the inserted lock buckle 2. Then the steel plate body 1 is controlled to be inserted downward until it is flush with the top surface of the adjacent steel plate body 1. At this time, the bottom of the inserted lock buckle 2 is in conflict with the top surface of the adjacent first docking rod 11, and the two sets of lock buckles 2 are fitted and in conflict with each other. During this process, the sliding rod 4 is not installed inside the lock buckle 2 above the docking groove 15, and the sliding rod 4 needs to be installed on the other side for support. After completion, the push rod 9 is inserted into the guide groove 10, so that the tip position of the push rod 9 is continuously moved downward and the sealing gasket 8 is pushed from the mounting groove 7 to the side of the adjacent lock buckle 2. After the push rod 9 in the two sets of lock buckles 2 are inserted, the sealing gasket 8 is pushed out of the guide groove 10. When the sealing gasket 8 is in the reset state, half of the whole is in the guide groove 10 and the other half is in the mounting groove 7. When it is pushed out by the push rod 9, half of it is in the mounting groove 7 and the other half is pushed out of the mounting groove 7, and it is sealed against the position of the lock buckle 2 on the other side.

[0043] When the bottom surface of the limit block 31 conflicts with the top surface of the lock buckle 2, it indicates that the push rod 9 has been inserted, and the connection and sealing operation of a group of steel sheet piles is completed. Then the above operations are repeated in sequence to complete the mutual docking of a circle of steel sheet piles. When the last group of steel plate bodies 1 needs to be installed, the docking grooves 15 on both sides of the third docking rod 13 at the bottom of the steel plate body 1 are respectively fitted with the outer walls of the adjacent lock buckles 2. At this time, there is no need to install the sliding rod 4 inside the lock buckle 2 of the steel plate body 1. The lock buckles 2 on both sides can be directly plugged into the two adjacent groups of lock buckles 2. After the steel plate body 1 is inserted, the above-mentioned push rod 9 insertion operation is performed to complete the sealing.

[0044] When it is necessary to remove the steel plate body 1, the driving blocks 30 on both sides of the steel plate body 1 are clamped by the mechanical arm, and the upward pulling driving block 30 drives the wire rope 28 to pull the bevel gear block 22 to slide in the sliding groove 23, compressing the return spring 25 while releasing the engagement state between the bevel gear block 22 and the engaging groove 24. Then, the steel plate body 1 is pulled up to contact and connect the steel plate body 1 with the first docking rod 11, the second docking rod 12 or the third docking rod 13 below. At this time, there is no need to judge whether the first docking rod 11, the second docking rod 12 or the third docking rod 13 below the steel plate body 1, which improves the removal efficiency. If this structure is not set, directly pulling the steel plate body 1 up and withdrawing it will cause the adjacent lock buckle 2 to press the first docking rod 11 or the second docking rod 12 below, so that the removal process must be removed in reverse order according to the original installation order, and sometimes it is difficult to judge which one is installed first and which one is installed later. This problem is effectively solved by setting this structure, which improves the removal efficiency.

[0045] It is worth noting that: since when the steel plate body 1 is inserted into the soil layer, the force at the bottom is mainly applied to the first docking rod 11, the second docking rod 12 and the third docking rod 13, the first docking rod 11, the second docking rod 12 and the third docking rod 13 will be worn or even deformed by impact during use. At this time, if the first docking rod 11, the second docking rod 12 and the third docking rod 13 are designed to be integrated with the steel plate body 1, it will be difficult to repair the bottom of the steel plate body 1 after deformation. Through this separate combined installation method, when the steel plate body 1 is pulled out, the first docking rod 11, the second docking rod 12 and the third docking rod 13 at the bottom are automatically detached and left underground. After being pulled out, the steel plate body 1 can be reinstalled with new first docking rods 11, the second docking rod 12 and the third docking rod 13. Among them, the structure of the first docking rod 11, the second docking rod 12 and the third docking rod 13 is simple, which is only a rod-shaped structure with some slot designs. The production and use cost is low, and the replacement is convenient and efficient. The cost of direct detachment after use is relatively low, and the overall service life of the steel plate body 1 can also be extended.
