Foundation structure of newly-built elevator above tunnel and construction method of foundation structure
The invention relates to a foundation structure of a newly-built elevator above a tunnel and a construction method of the foundation structure, the foundation structure comprises a compensation type reinforced concrete box raft foundation composed of a compensation foundation raft plate and a compensation foundation box-shaped structure, the compensation foundation box-shaped structure is arranged above the compensation foundation raft plate, and the compensation foundation box-shaped structure and the compensation foundation raft plate form an integral structure; the compensation foundation box-shaped structure is used for connecting and supporting an upper structure column of a newly-built elevator above the compensation foundation box-shaped structure, and a foundation grouting reinforcing body is arranged below the compensation foundation raft. The method has the advantages that 1) the method is suitable for newly building the elevator above the tunnel, and fills the technical blank; the method has the advantages of being simple in structure, convenient to operate, free of pile forming (sinking), capable of shortening the exposure time of the foundation pit, reducing the enclosure cost, reducing soil disturbance, improving the safety degree, effectively reducing underground obstacles, effectively reducing the operation content and time close to the foundation pit, greatly improving the operation environment of a construction site, improving the construction safety degree and being high in practicability, economical efficiency and applicability.
本发明涉及一种隧道上方新建电梯的基础结构及其施工方法，包括由补偿基础筏板和补偿基础箱形结构构成的补偿型钢筋混凝土箱筏基础，其中补偿基础箱形结构设置在补偿基础筏板的上方且两者构成整体结构，补偿基础箱形结构用于连接并支撑上方新建电梯的上部结构柱，在补偿基础筏板的下方设置有地基注浆加固体。本发明的优点是：1）适用于隧洞上方新建电梯情况，填补技术空白；2）无须成（沉）桩；3）基坑暴露时间缩短，围护成本降低，土体扰动减少，安全度提升；4）有效减少地下障碍物；5）有效减少临近基坑作业内容与时间，极大改善施工现场作业环境，提升施工安全度；6）具有较强的可实施性、经济性和适用性。
