Pushing structure system and pushing method
The invention provides a pushing structure system. The pushing structure system comprises a bearing platform, a tension bar, a pushed piece, a pushing driving piece, a counter-force beam and a sliding plate. The bearing platform is located between the existing structure and the sliding plate, the sliding plate is arranged next to the bearing platform, and the upper surface of the sliding plate is flush with the upper surface of the bearing platform; one end of the tension bar is connected with the bearing platform, and the other end of the tension bar is connected with the counter-force beam; one end of the pushing driving piece is connected with the counter-force beam, the other end of the pushing driving piece abuts against the pushed piece, and the pushed piece on the sliding plate is pushed to the bearing platform through the pushing driving piece. According to the method, the pile cap pile foundation cannot move forwards to extrude foundation soil in the pushing process, the influence on the adjacent existing structure is completely avoided, and the operation safety of the existing line is completely ensured. In addition, large-area reinforcement treatment does not need to be conducted on the foundation, and the device is simple in structure and clear in force transmission; a plurality of pushed pieces can be pushed at the same time and do not interfere with one another, the construction period can be effectively shortened, and the manufacturing cost is saved.
本发明提供了一种顶推结构体系，包括承台、拉力杆、被顶推件、顶推驱动件、反力梁和滑板；所述承台位于既有构筑物和滑板之间，所述滑板紧挨承台设置且滑板的上表面与承台的上表面平齐；所述拉力杆的一端与承台连接，其另一端与反力梁连接；所述顶推驱动件的一端连接反力梁，其另一端顶住被顶推件，通过顶推驱动件将滑板上的被顶推件顶推至承台上。本发明实现了顶推过程中承台桩基不会前移挤压地基土，完全避免了对紧邻的既有构筑物的影响，完全确保既有线路的营运安全。此外，无需对地基进行大面积加固处理，装置的结构简单、传力明确；可以实现多台被顶推件同时顶推，且不会相互干扰，可以有效地缩短工期，节约造价。
