When there are buildings around, for the protection of the buildings, toFoundation pit supportingThe safety level has higher requirements, which are set according to the type of surrounding buildings.

When there are protective historic buildings and important municipal transportation facilities around, the safety level of foundation pit support should be set as level 1, and the supporting scheme adopted is: underground diaphragm wall+Horizontal support. Among them, the horizontal support is concrete support or steel support, and it should have higher requirements on the stiffness of the support, and generally have certain restrictions on the length of the support. When necessary, it is necessary to add servo loading device. In the process of foundation pit excavation, the servo loading device will adjust the axial force of the support according to the deformation around the foundation pit.

The undisturbed influence of the construction process on the surrounding buildings can be reduced by using the undisturbed concrete pile as the foundation pit enclosure structure. Using prestressed fish-belly steel support as horizontal support can improve the construction speed and thus reduceThe foundation pitTo ensure the safety of the surrounding buildings of the foundation pit.
