Permanent steel casing integrated pile method for bridge crossing existing high-speed line roadbed
The invention relates to a permanent steel casing integrated pile method for a bridge crossing an existing high-speed line roadbed, which comprises the following steps of: after constructing an outer side steel casing, pouring a reinforced concrete hardened layer on the periphery and reserving a slurry ditch, and then installing an I-shaped steel buttress; mounting an assembly type verticality adjusting bracket, supporting a verticality adjusting jack on the I-shaped steel buttress, and fixing the tail part of the verticality adjusting jack with the assembly type verticality adjusting bracket; and inner side pier column permanent steel casing sinking construction is conducted in the outer side steel casing, and the sinking perpendicularity of the inner side permanent steel casing is adjusted through a hydraulic jack and a perpendicularity adjusting jack. The method has the beneficial effects that in the construction process, the laser inclinometer pipe and the verticality adjusting jack are matched to adjust the verticality of the permanent steel casing of the inner side pier column, the construction convenience is high, the construction error is small, and it can be ensured that the construction precision of the integrated pile column meets the standard requirement.
本发明涉及一种穿越既有高速线路路基的桥梁永久性钢护筒一体化桩柱方法，包括以下步骤：施工外侧钢护筒后，在四周浇筑钢筋混凝土硬化层并预留出泥浆沟，随后安装工字钢支墩；安装装配式调垂支架，将调垂千斤顶支承在工字钢支墩上并将尾部与装配式调垂支架固定；在外侧钢护筒内进行内侧墩柱永久性钢护筒沉放施工，通过液压千斤顶和调垂千斤顶调整内侧永久性钢护筒沉放垂直度。本发明的有益效果是：施工过程中配合上激光测斜管和调垂千斤顶对内侧墩柱永久性钢护筒进行调垂，施工便捷性高、施工误差小，可以确保一体化桩柱的施工精度满足规范要求。
