Background

The concrete interlocking block structure is mutually locked, embedded and meshed through the building blocks, is favorable for load transmission and diffusion, and belongs to an absolute rigid plate on an elastic foundation. The small scale absolutely rigid slabs can be subjected to less flexural tensile stress than the monolithic concrete pavement slab, and therefore can be reduced in thickness, but the requirements for compressive strength are relatively higher. This arrangement has the advantage of creating a regular "rough-textured" surface by the seams, which facilitates vehicle travel and also tends to prevent the driver from traveling too quickly. Meanwhile, the small-scale rigid plate has good stress bearing performance, can greatly reduce the thickness of the surface layer, and is often suitable for places bearing heavy load and running slow traffic, such as wharfs, storage yards and the like. And the interlocking blocks need to be dismantled aiming at the condition that the stock dump which is old in service life needs to be rebuilt.

The traditional process for removing the interlocking blocks comprises the following steps: first, the lateral concrete or lateral interlocking blocks are removed using a crusher. The interlocking blocks are then manually removed using a crowbar and a small hammer. The reusable interlocking blocks are transported to a designated area in the field area by a trolley, and the damaged interlocking blocks are transported out of the field area by a dump truck.

The problems encountered in the interlocking block removal construction by the conventional process are mainly as follows:

(1) the breakage rate is high, and the breakage of the interlocking blocks is caused in the mechanical construction process because the crusher is adopted to assist manual removal.

(2) The construction efficiency is low, the manufacturing cost is high, manual large interlocking blocks are removed, damage rate of the interlocking blocks is reduced, the utilization rate of the manual interlocking blocks is low, and manual removing efficiency is low.

In view of the above technical problems, improvements are needed.
