Steel pipe column construction method adopting first insertion method
The invention relates to the field of high-precision installation of steel pipe columns, in particular to a first insertion method steel pipe column construction method, which comprises the following steps of: paying off and positioning, and embedding a pile casing; after positioning, pile hole forming is determined, and a bottom reaming drill bit is used for reaming; erecting a reinforcement cage and adjusting the position of the reinforcement cage; a reinforcement cage is placed in the pile hole; the verticality adjusting machine is hoisted and moved to the position above the pile hole, the verticality adjusting machine is moved to the measuring position, and the verticality adjusting machine is kept horizontal; hoisting the steel pipe column, hoisting the steel pipe column into a verticality adjusting machine, and adjusting the horizontal elevation and the verticality of the steel pipe column through a control system; a guide pipe is embedded in the pile hole, and pile foundation concrete is poured; and concrete is replaced, and pouring is continuously conducted in the steel pipe column. The method has the effect that the installation risk that the steel pipe column cannot be inserted into the column foundation due to the fact that the setting time of the super-retarding concrete is difficult to control is avoided.
本申请涉及钢管柱高精度安装的领域，尤其是涉及一种先插法钢管柱施工方法，包括步骤：放线定位，埋设护筒；定位后确定桩孔成孔，使用扩底钻头进行扩孔；搭设钢筋笼，调整钢筋笼位置；在桩孔内下放钢筋笼；吊装调垂机移动至桩孔上方，将调垂机移动至测定位置，保持调垂机水平；吊装钢管柱，将钢管柱吊放至调垂机内，通过控制系统对钢管柱水平标高和垂直度进行调整；在桩孔内埋设导管，浇筑桩基混凝土；更换混凝土，继续对钢管柱内进行浇筑。本申请具有避免由于超缓凝混凝土凝固时间难以控制而产生钢管柱无法插入柱基内的安装风险的效果。
