The cross-sections of the two openings 4 are consistent with the cross-sections of two adjacent steel sheet piles. The positioning block 3 is provided with a driving assembly to drive the positioning block 3 to move along the guide frame 1.

[0028] During use, during construction, the guide frame 1 is set up and one of the steel sheet piles is inserted through the opening 4. During the insertion process, the telescopic cylinder 11 drives the positioning block 3 to move downward. After the insertion is completed, the positioning block 3 is driven to move to the highest position by the telescopic cylinder 11, and another steel sheet pile is inserted. After the insertion is completed, the positioning block 3 is driven to move to the highest position by the telescopic cylinder 11 again. The insertion of a pair of steel sheet piles is completed. At this time, the positioning block 3 is higher than the height of the inserted steel sheet piles. The fixed plate 18 is moved to the pre-insertion position of the next pair of steel sheet piles by the driving assembly, and the next pair of steel sheet piles are inserted until all the steel sheet piles are inserted into the predetermined positions.

[0029] By adopting this technical solution, the present invention realizes the limitation of the steel sheet piles by setting a positioning block 3 that can be telescoped up and down and a corresponding opening 4, thereby avoiding the displacement of the steel sheet piles; by setting the opening 4 and the positioning block 3, the steel sheet piles can be passed through and at the same time be limited.

Any two adjacent limit plates 13 are slidably connected, and the limit plate 13 with the largest size is connected to the fixed plate 18. The limit plate 13 with the smallest size is slidably connected with a reinforcing plate 14, and the upper end of the reinforcing plate 14 is connected to the bottom surface of the positioning block 3. Except for the limit plate 13 with the largest size, two vertical end faces of the remaining limit plates 13 and the side surfaces of the reinforcing plates 14 are horizontally provided with two fixing rods (when the steel plate is inserted, the positioning block 3 moves to the highest position, the upper end of the steel sheet pile is lower than the fixing rod at the lowest position to facilitate the movement of the positioning block 3).

On the one hand, by setting up multiple U-shaped limit plates 13, not only can the limit plates 13 be extended and retracted as the telescopic cylinder 11 works, but the fixed rods can also move with the limit plates 13 to better limit the limit plates 13. On the other hand, by setting up the rollers 17, the rollers 17 can rotate as the steel sheet piles move downward, thereby reducing the resistance of the steel sheet piles to the downward movement.

By adopting this technical solution, the present invention realizes that different positioning blocks 3 can be adapted to steel sheet piles of different sizes by setting positioning blocks 3 of different sizes, thereby expanding the scope of use of the steel sheet pile construction positioning device, and by setting the second slide rail and the second slider, the position of the limiting block can be adjusted based on steel sheet piles of different sizes, so as to better prevent the steel sheet piles from shifting.

[0034] In another technical solution, the positioning plate 12 is provided with a sliding opening along its length, and two detachable first threaded rods are disposed within the sliding opening. Each first threaded rod is provided with two first nuts. When the limiting plate 13 needs to be secured, the two first threaded rods are respectively inserted into the sliding opening, with the limiting plate 13 positioned between the two first threaded rods and secured with the first nuts. Using this technical solution, the present invention secures the limiting plate 13 by providing the sliding opening, the first threaded rods, and the first nuts.

[0035] In another technical solution, the driving assembly includes two channels 25 with T-shaped horizontal cross-sections formed by a recess at one end of the positioning block 3 (the positioning block 3 and the support plate 5 are in sequence in the moving direction of the fixed plate 18), a driving block 6 that can pass through the channel 25 (slide through it up and down) (the driving block 6 is T-shaped to match the channel 25, and the long side of the driving block 6 passes through the channel 25 horizontally), a driving rod 7 connected to the driving block 6 (the end of the long side of the driving block 6 is connected to the driving rod 7), a support plate 5 provided on two guide frames 1 (two guide frames 1 are connected to one support plate 5), and two forward and reverse motors provided on the support plate 5, the end of the output shaft of the forward and reverse motor is connected to a gear 9, and the driving rod 7 is provided with meshing teeth 8 (a plurality of meshing teeth 8 are arranged along the length direction of the driving rod 7), and the meshing teeth 8 are engaged with the gear 9 to drive the positioning block 3 to move along the guide frame 1. By adopting this technical solution, in the present invention, when the positioning block 3 moves up and down, the driving block 6 passes through the channel 25 and separates from the channel 25; when the positioning block 3 moves from the lowest position to the highest position, the driving block 6 passes through the channel 25 and is located in the channel 25; at this time, the positioning block 3 can be driven to move by the driving rod 7. This arrangement can not only realize the up and down movement of the positioning block 3, but also realize the horizontal movement of the positioning block 3.

When the length of the fixing rod needs to be adjusted, the second nut is turned to move the second nut away from the first vertical plate 22. After the length is adjusted, the second nut is moved toward the first vertical plate 22 to fix the second threaded rod. By adopting this technical solution, the length of the fixing rod can be adjusted by setting the fixing tube 15, the rod body 16, the first vertical plate 22, the second vertical plate 24, and the second threaded rod.
