Problems solved by technology

[0007] The purpose of the present invention is to provide a method for opening and reforming the side walls of underground operating stations, so as to alleviate the existing problems in the prior art that no supporting measures are used during the demolishing period, the large-scale demolition and reconstruction cannot be carried out, the construction period is long, and the unreserved In the case of structural conditions, the traditional method has a greater impact on the existing structure, and cannot guarantee structural and operational safety issues

Embodiment 1

[0056] like Figure 1-Figure 15 As shown, it is a schematic structural diagram of the method for opening and reforming the side wall of the underground operating station provided by the embodiment of the present invention. The method for opening and reforming the side wall of the underground operating station is described in conjunction with the accompanying drawings. The specific structure and steps are as follows.

[0057] The embodiment of the present invention provides a method for opening a hole in the side wall of an underground operating station, such as Figure 1-Figure 15 As shown, the construction method of "supporting first, demolishing later, layered and segmented reconstruction, and two structural system conversions" was adopted to simultaneously demolish multiple connection parts of the side wall 5 of the station, and realize the multi-layer penetration reconstruction of the old and new structures ,Proceed as follows:

[0058] Step 1. Vertically erect temporary ...

Abstract

The invention provides a method for opening a hole in the side wall of an underground operating station, which relates to the technical field of underground engineering. Temporary supports with axial force automatic compensation system were erected vertically between the adjacent floors in the existing station to realize the force conversion from the existing wall panel system to the temporary support system, effectively reducing the impact of demolition construction on the existing Due to the impact of the station, multiple connection parts of the side wall of the station were simultaneously removed, and the new and old structures were reconstructed in multiple layers, and new beams and columns were built to connect and support the old and new structural panels of each layer, and the rigidity of the beams and columns was enhanced to facilitate on-site construction. The conversion from the wall panel stress system to the beam-column stress system improves the renovation efficiency, ensures the safety and reliability of the construction process, and has a high promotion value in all existing structural renovations.

Description

technical field [0001] The invention relates to the technical field of underground engineering technology, in particular to a method for opening holes in side walls of underground operating stations. Background technique [0002] In recent years, with the advancement of urbanization, the construction of urban underground space has developed rapidly, and the urban rail transit network has been constantly updated and adjusted. There must be transfer requirements between the original rail network and the newly planned rail network. In order to meet the unreserved connection conditions There is an underground station for transfer and connection, and the side wall of the existing station needs to be penetrated and modified to meet the transfer requirements of the newly planned line network. [0003] Subway transportation carries the main task of decommissioning in the city. In the face of the transformation requirements of transfer stations, it is necessary to complete the transf...
