Analysis of Key Technologies for Supporting Construction of Existing Basement Renovation
The background project is located near the operating subway station and section tunnel,and the environment is complex and varia-ble.This project requires the renovation and expansion of the existing basement,which is difficult to construct.In order to meet this chal-lenge,we have adopted a variety of support replacement technologies,including full frame support,section steel slant support,section steel support replacement,steel pipe support replacement,reinforced concrete slab and strip,etc.By comprehensively applying these technolo-gies,the problem of adding cast-in-place piles to the existing basement was solved,and the deformation of surrounding buildings was controlled within the specified range,successfully completing the construction task.This experience provides valuable reference and inspira-tion for the implementation of similar projects in the future.
