Transformation method for connection of existing large-span column-free station and newly-built structure
The invention relates to a transformation method for connection of an existing large-span column-free station and a newly-built structure, and belongs to the technical field of rail transit structures. Comprising the steps that an existing station is divided into a plurality of construction sections in the length direction for section-by-section construction, and first top plates of the construction sections are subjected to soil unloading; an enclosure is arranged in the existing station, and a part of an enclosure structure of the existing station is dismantled from the side where the newly-built structure is located; a large hole needing to be formed is planned in the position of the side wall of the existing station, the large hole is planned into a plurality of small holes in the length direction of the side wall of the existing station, each small hole is divided into a first-stage hole and a second-stage hole, and skip bay hole forming construction is carried out; a first-stage supporting beam and a supporting column are arranged at the opening of the first-stage hole and connected with a second top plate and a bottom plate of the newly-built structure; and a second-stage supporting beam is arranged at the opening of the second-stage hole, and the first-stage supporting beam and the second-stage supporting beam are connected and connected with a second top plate and a bottom plate of the newly-built structure.
本申请涉及一种既有大跨无柱车站与新建结构连接的改造方法，属于轨道交通结构技术领域。包括将既有车站沿长度方向划分为多个施工区段进行逐段施工，对施工区段的第一顶板进行卸土；在既有车站站内设置围蔽，从新建结构所在一侧拆除部分既有车站的围护结构；在既有车站侧墙处规划需要开设的大洞，并将其沿既有车站侧墙的长度方向规划为多个小洞，将各个小洞划分为一期开洞和二期开洞，进行跳仓开洞施工；在一期开洞洞口处设置一期支撑梁和支撑柱，并与新建结构的第二顶板和底板进行连接；在二期开洞洞口处设置二期支撑梁，将一期支撑梁和二期支撑梁进行连接，并与新建结构的第二顶板和底板进行连接。
