Large cantilever bent cap support system and construction method
The invention relates to a large cantilever bent cap support system and a construction method. The large cantilever bent cap support system comprises a bent cap, a large height difference support system body, a bent cap height difference adjusting support, a shaped pier column connecting piece, a transverse underpass tunnel, a foundation, a shaped steel mold, a long steel pipe column and a short steel pipe column. For construction of a large-cantilever bent cap support system, a foundation is constructed on the ground, a long steel pipe column and a short steel pipe column are installed on the foundation, the long steel pipe column and the short steel pipe column are fixed through an upper horizontal beam, a lower horizontal beam and an inclined support, and the large-height-difference support system is fixedly connected with the columns through shaped pier column connecting pieces. Double-spliced steel beams are installed on the upper portions of the long steel pipe columns and the short steel pipe columns, shaping steel molds are installed on the upper portions of the double-spliced steel beams, and the shaping steel molds at the two ends of the bent cap are adjusted through a bent cap height difference adjusting support. The method can effectively reduce the engineering cost and accelerate the construction speed, and can obtain better technical and economic benefits when being applied to actual engineering.
本发明涉及一种大悬挑盖梁支架体系及施工方法，包括盖梁、大高差支架体系、盖梁高差调整支架、定型化墩柱连接件、横向下穿隧道、基础、定型化钢模、长钢管柱、短钢管柱。针对大悬挑盖梁支架体系施工，采用在地面施工基础，基础上安装长钢管柱和短钢管柱，长钢管柱和短钢管柱之间采用上部水平梁、下部水平梁和斜支撑进行固定，大高差支架体系采用定型化墩柱连接件与橔柱连接固定，长钢管柱和短钢管柱上部安装双拼型钢梁，双拼型钢梁上部安装定型化钢模，盖梁两端定型化钢模通过盖梁高差调整支架进行调整。本发明可以有效降低工程成本，加快施工速度，应用于实际工程中可取得较好的技术经济效益。
