[0024] In this embodiment, by providing the connection block 104, the connection between the installation blocks 102 can be strengthened to ensure the overall stability of the Larsen steel sheet pile enclosure structure.

[0025] Specifically, the connection relationship between the limiting rod 3 and the nail head 2 is a movable plug-in connection.

[0026] In this embodiment, a limit rod 3 is provided, and the bidirectional screw 303 is driven to rotate by rotating the handle 5. The rotating bidirectional screw 303 is threadedly matched with the nut seat 302 to displace the nut seat 302 and the limit rod 3. When one end of the limit rod 3 is inserted into the limit hole inside the nail head 2, the nail head 2 can be limited.

[0027] Specifically, a guide block 4 is fixedly provided on the top of the nut seat 302, one end of the guide block 4 is located in a slide groove on the top of the inner wall of the limiting plate 1, and the connection relationship between the limiting plate 1 and the guide block 4 is a sliding connection.
