Deep foundation pit support pile reinforcing method
The invention discloses a deep foundation pit support pile reinforcing method, which is characterized in that after the construction of a previous reinforcing structure is completed, the next earth excavation and reinforcing structure construction are carried out, and during the construction of the reinforcing structure, firstly, the side wall of a waist beam is drilled, steel bars are planted, an anchoring steel plate is mounted at the end part of a support steel bar, then a support template is erected, and concrete is poured; after the strength of the concrete reaches the standard, the support formworks are dismantled to obtain supports, and the supports are distributed in pairs between the adjacent waist beams with included angles on the same layer; firstly, steel pipes are cut according to the distance between the anchoring steel plates on the paired supports, then the steel pipes are hoisted to the installation position, the installation angle is adjusted, the installation height is checked, then the two ends of the steel pipes are welded to the anchoring steel plates of the paired supports respectively, the anchoring steel plates are polished and cleaned before welding, weld seam flaw detection is conducted after welding, and it is ensured that weld seams are reliable. The method is simple in construction, short in construction period, low in dead weight and safe and reliable in supporting.
本发明公开了一种深基坑支护桩加固方法，在上一道的加固结构施工完成后即进行下一道的土方开挖和加固结构施工，进行加固结构施工时：先在腰梁侧壁钻孔、植筋，在支座钢筋端部安装锚固钢板，然后支设支座模板、浇筑混凝土，直至混凝土强度达标后拆除支座模板获得支座，支座在同层呈夹角的相邻腰梁之间成对分布；先根据各对成对支座上锚固钢板之间的距离切割钢管，然后将钢管吊运至安装位置，并调整安装角度、校核安装高度，然后将钢管两端分别焊接在成对支座的锚固钢板上，焊接前打磨清理锚固钢板，焊接后进行焊缝探伤，确保焊缝可靠。本发明施工简单、施工周期短，自重低，支撑安全可靠。
