Construction technology for connecting newly-built underground passage and existing underground structure
The invention discloses a construction technology for connecting a newly-built underground passage and an existing underground structure, and relates to the technical field of municipal construction. According to the construction technology, an internal structure part of a connecting passage is built back, an externally-expanded force transmission belt is constructed at the joint of the connecting passage and an existing sunken plaza, and the externally-expanded force transmission belt is reliably connected with a side wall of an existing sunken plaza structure in a steel bar planting mode; after concrete of the internal structure part of the connecting passage which is constructed in advance reaches the design strength, a hole is opened and the side wall of the existing sunken plaza structure in the area corresponding to the joint is chiseled away; during chiseling, part of side wall steel bars are reserved and anchored into newly-made frame beams and columns, and it is guaranteed that the newly-made frame beams and columns are reliably connected with the side wall of the existing sunken plaza structure. The externally-expanded force transmission belt which is constructed in advance can resist outside water and soil pressure and ground overload for the existing structure after hole opening and chiseling, meanwhile, a certain waterproof protection effect can be provided for connector construction, and finally the purpose of guaranteeing project safety construction is achieved.
一种新建地下通道与既有地下结构连接的施工工艺，本发明涉及市政建设技术领域，回筑连接通道内部结构部分，在连接通道与既有下沉广场接口处先施工外扩传力带，外扩传力带采用植筋方式与既有下沉广场结构侧墙可靠连接；待先期施工的连接通道内部结构部分的混凝土达到设计强度后，开洞凿除接口对应区域的既有下沉广场结构侧墙；凿除时保留部分侧墙钢筋，锚入新做框架梁、柱中，确保新做框架梁、柱与既有下沉广场结构侧墙可靠连接。其先期实施的外扩传力带能为开洞凿除后的既有结构提供抵挡外侧水土压力以及地面超载的作用，同时也能为接口施工提供一定的防水保护作用，最终达到保证项目安全施工的目的。
