With the continuous development of cities, some old buildings need to be dismantled or displaced so as to facilitate the expansion of new roads, the construction of new buildings and the like. For valuable buildings such as historical relics, historic buildings and the like, in order to not destroy the original appearance of old buildings, the method of displacing the whole buildings to be outside the range of reconstruction and extension is generally adopted for treatment.

The displacement of the building is similar to the horizontal transportation of large-scale equipment, and the difference is that the deformation resistance of the building is poor, so when the building is displaced, the building is reinforced according to the actual situation, then a underpinning beam system and a walking mechanism are constructed below the building, then a lower slideway is constructed along a migration route, and finally, external jacking force or traction force is applied to the underpinning beam system to enable the building to be displaced to a new foundation along the lower slideway along with the walking mechanism.

In many types of ancient coffin chambers, a typical brick chamber coffin is constructed by digging a pit from the ground downwards, making a hole transversely at the bottom of the pit, building the coffin chamber in the transverse hole, and placing the coffin in the coffin. Some brick rooms are built with slope graves, and some brick rooms are built at the bottom of the vertical cave, so that the graves of the brick rooms can be developed into quite complicated forms because transverse caves are not opened any more and the brick building method is different. The ancient graves have two structural forms, one is built by large-scale hollow bricks, the other is built by small-scale rectangular bricks, and the ancient graves generally comprise a grave door, a rain channel, a grave room and the like. The building of the brick house grave is characterized in that no bonding material is used between bricks, and an irregular, stable and huge underground building space is built completely depending on the acting force of the building structure.
