The dock stone 330 is adhered to the surface of the concrete side plate 320 by epoxy resin or connected to the concrete inside by bolts, with a thickness of 50mm and continuously laid along the full length of the side plate 320.

[0041] The top locking mechanism 200 includes a door bolt arranged at the upper part of the door body 100 by welding or bolt connection. The door bolt is formed by welding a steel plate and horizontally installed on both sides of the top of the door body 100, with a trapezoidal cross-section at the end. In other embodiments, the door bolt can use a hydraulic drive telescopic rod (diameter 200mm).
