Rapid connection construction method for steel pipe piles in support limited area
The invention relates to the technical field of building construction, and discloses a rapid connection construction method for steel pipe piles in a support-limited area, which comprises the following construction steps: 1) leveling a site; 2) measuring and positioning the pile position of the steel pipe pile: setting a benchmark on a piling site or near the piling site; (3) a drilling machine is in place; (4) steel pipe pile hole forming is conducted, specifically, holes are formed through construction of a drilling machine and drilled to the designed elevation of the pile bottom; (5) grouting is conducted, specifically, during grouting, the pressure is controlled, grout is made to evenly rise upwards till the grout emerges out of an orifice, a grouting pipe is lifted upwards to supplement the grout in a segmented mode, grouting is kept full, and grouting is stopped after returned grout is thick; (6) steel pipes are lowered, specifically, a plurality of steel pipe sections and a plurality of connecting pipes are included, and the first steel pipe section is lowered into the hole till the end of the remaining first steel pipe section is exposed out of the hole; the end of the first steel pipe is in butt joint with the lower end of the second steel pipe through the connecting pipe, the connecting pipe is fixed to the first steel pipe and the second steel pipe in a spot welding mode, the second steel pipe continues to be put down, and the rest can be done in the same way, so that the multiple steel pipes are put down into the hole.
本发明涉及建筑施工的技术领域，公开了支撑受限区钢管桩快速连接施工方法，包括以下施工步骤：1)平整场地；2)钢管桩桩位测量定位：在打桩现场或附近需设置水准点；3)钻机就位；4)钢管桩成孔：钻机施工成孔，并钻孔至桩底设计标高；5)注浆：注浆时控制压力，使浆液均匀上冒，直至泛出孔口后，上提注浆管分段补浆，保持注浆饱满，待返浆较浓后停注；6)下放钢管：包括多节钢管和多个连接管，首先下放第一节钢管至孔内，直至余下第一节钢管的端部显露在孔外；通过连接管将第一节钢管的端部与第二节钢管的下端部对接，并将连接管与第一节钢管、第二节钢管点焊固定，继续下放第二节钢管，以此类推，从而将多节钢管下入孔内。
