Problems solved by technology

In this way, the supporting components needed for temporary force transmission in the construction stage are permanently discarded in the main structure, and can no longer play their role, which increases material loss, wastes the project cost, and is inconvenient to use.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0033] Example. The post-cast belt replacement method for underground structures is characterized in that, using detachable support components, combined with the construction sequence and the use of existing support structural components, all the support components can be recycled, thereby significantly saving the cost of post-cast belt replacement. material consumption, and at the same time create conditions for the recycling of support members.

[0034] The post-cast belt replacement method for underground structures includes the following steps:

[0035] ① Construct vertical support members around the foundation pit, excavate the foundation pit after the construction is completed, and simultaneously construct multiple horizontal support members for foundation pit support from top to bottom;

Abstract

The invention discloses a underground structure post-cast strip support replacement method; and detachable support replacement components are adopted, and all support replacement components can be recovered by using existing support structure components according to the construction sequence, so that the consumption of materials needed for post-cast strip support replacement is obviously saved, and conditions are created for the recycling of the support replacement components. After the support replacement construction of an underground structure is finished, the support replacement components can be conveniently recovered, so that the material consumption is reduced, and the engineering construction cost is saved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a post-cast belt support replacement method for an underground structure. Background technique [0002] In the excavation construction of underground structures in soft soil areas, it is often necessary to take support measures on the side of the foundation pit to ensure that the soil outside the foundation pit does not deform and slip into the foundation pit. When the depth of the basement is large or the surrounding conditions of the foundation pit are complex and sensitive to soil deformation, the support method of internal support plus cast-in-place piles around the pit or continuous wall is often used. During the excavation construction, the supporting structure is constructed according to the design requirements of the supporting structure. Then, when the main body of the basement structure is constructed upwards from the foundation floor, the constructed main structure is used ...
