Complex stratum steel pipe column hole forming method and steel pipe column construction method
The invention discloses a complex stratum steel pipe column hole forming method and a steel pipe column construction method, and relates to the technical field of steel pipe column construction. The complex stratum steel pipe column pore-forming method comprises the steps that the pore-forming position of a steel pipe column is determined on a construction site, and a plurality of grouting positions are arranged outside the pore-forming position in the circumferential direction of the pore-forming position; drilling is conducted at the grouting position to form a grouting hole, and grouting is conducted in the grouting hole to reinforce the stratum on the periphery of the hole forming position; and drilling at the hole forming position to form a steel pipe column hole. A plurality of grouting positions are arranged outside a hole forming position in the circumferential direction of the hole forming position, and hole drilling and grouting are performed on the grouting positions, so that a circle of grouting reinforcement structure is formed in the stratum around the hole forming position, hole collapse at the hole forming position in the hole forming process can be prevented, the ground subsidence phenomenon can be controlled, and the hole forming quality is improved. The risk that the heavy machinery overturns when walking in a narrow field is reduced; compared with the prior art, the method is simple in construction, low in construction cost and high in engineering benefit.
本申请公开了一种复杂地层钢管柱成孔方法及钢管柱施工方法，涉及钢管柱施工技术领域。该复杂地层钢管柱成孔方法，包括：在施工现场确定钢管柱的成孔位置，在成孔位置的外部沿其周向设置若干个注浆位置；在注浆位置钻孔以形成注浆孔，在注浆孔内注浆以加固成孔位置周边的地层；在成孔位置处钻孔以形成钢管柱孔。通过在成孔位置的外部沿其周向设置若干个注浆位置，并在注浆位置钻孔、注浆，进而在成孔位置周边的地层中形成一圈注浆加固结构，不仅可防止在成孔位置处成孔过程中出现塌孔，而且还能够控制地面下沉现象，减小重型机械在狭小场地中行走倾覆的风险；与现有技术相比，本申请施工简单，施工成本低，工程效益高。
