Existing building low-clearance inner foundation foundation steel pipe pile reinforcing construction technology
The invention discloses an existing building low-clearance inner foundation steel pipe pile reinforcement construction process which is particularly suitable for low-clearance part foundation reinforcement engineering. The technology comprises the following steps that steel pipe piles are machined in a segmented mode, and the length of each steel pipe pile segment is smaller than the clearance height of a foundation reinforcement part of a foundation; processing a guide structure at the lower end of the bottommost steel pipe pile; lining pipes are mounted in the upper parts of the bottommost steel pipe pile and the middle section steel pipe pile; the steel pipe piles are constructed, the two steel pipe piles are in butt joint through the lining pipe, and welding connection is adopted; a plurality of anchoring steel bars are welded in a steel pipe at the upper end of the uppermost steel pipe pile, are uniformly distributed according to a certain angle and are anchored into the bearing platform; and a bearing platform is constructed at the top of the uppermost steel pipe pile. According to the technology, through the segmented machining and lining pipe technology, the construction efficiency and the welding quality are improved, the stability and the bearing capacity of the overall structure are enhanced, and the technology is suitable for foundation reinforcement construction in the low-clearance and narrow space environment.
本发明公开了一种既有建筑低净空内地基基础钢管桩加固施工工艺，特别适用于低净空部位地基基础加固工程。该工艺包括以下步骤：将钢管桩分段加工，使每段钢管桩长度均小于地基基础加固部位的净空高度；在最底部钢管桩的下端加工导向结构；在最底部钢管桩和中间段钢管桩的上部管内安装内衬管；施工钢管桩，通过内衬管对接两节钢管桩，采用焊接连接；在最上部钢管桩的上端钢管内焊接多根锚固钢筋，锚固钢筋按一定角度均匀分布，并锚入承台内；在最上部钢管桩的顶部施工承台。本发明的工艺通过分段加工、内衬管技术，提高了施工效率和焊接质量，增强了整体结构的稳定性和承载力，适应低净空和狭小空间环境下的地基基础加固施工。
