Rectangular jacking pipe rear backrest structure and construction method thereof
The invention discloses a rectangular pipe jacking backrest structure and a construction method thereof, and the structure comprises a falling bottom plate which is provided with a first end close to a connecting channel and a second end far away from the connecting channel; the space frame comprises a structural plate and a plurality of frame columns, the frame columns are poured at the second end of the falling bottom plate, the structural plate comprises an original bottom plate with the elevation higher than that of the falling bottom plate and a multi-layer floor bearing plate arranged above the original bottom plate, and the original bottom plate and the multi-layer floor bearing plate are connected to the sides, away from the falling bottom plate, of the frame columns; the position of the lowermost floor bearing plate corresponds to the upper portion of the reaction frame, the lowermost floor bearing plate is connected to the middles of the multiple frame columns through hidden beams, and the outer diameter of the column sections, located between the original bottom plate and the lowermost floor bearing plate, of the frame columns is larger than that of the other column sections of the frame columns. The method solves the problem that when pipe jacking excavation construction is adopted for the connecting channel of the two underground structures, traditional construction is poor in economical efficiency.
本发明公开了一种矩形顶管后靠背结构及其施工方法，该结构包括：下落底板，其具有靠近连接通道的第一端和远离连接通道的第二端；以及空间框架，包括结构板和多根框架柱，多根框架柱浇筑于下落底板的第二端，结构板包括标高高于下落底板的原底板和设置于原底板的上方的多层楼承板，原底板和多层楼承板连接于多根框架柱的远离下落底板的一侧，最下层楼承板的位置与反力架的上部相对应，且最下层楼承板通过暗梁连接于多根框架柱的中部，框架柱的位于原底板和最下层楼承板之间的柱段的外径大于框架柱的其余柱段的外径。本发明解决了在两地下结构的连接通道采用顶管开挖施工时，传统施工经济性较差的问题。
