Reverse construction method steel pipe structure pile rotary excavating drilling and full-rotation combined post-insertion positioning method
The invention relates to the technical field of deep foundation pit supporting, and discloses a reverse construction method steel pipe structure pile rotary excavating drilling and full circle swinging combined rear inserting method positioning method which is characterized by comprising the following steps that S10, a long pile casing is placed; S20, a rotary drilling machine is used for drilling to form a hole; S30, a reinforcement cage is placed in the pile hole; S40, concrete is poured into the pile hole; S50, hoisting the steel pipe column; S60, the steel pipe column is inserted into the pile hole, the perpendicularity of the steel pipe column is monitored in real time according to the two-point one-line principle of full-rotation equipment and a universal platform, and the steel pipe column is inserted to the designed elevation; S70, pouring concrete in the steel pipe column; and S80, the tool column is dismantled, and gravel is backfilled. According to the technical scheme, the reverse construction method steel pipe structure pile rotary excavating drilling and full rotation combined post-insertion positioning method can guarantee the perpendicularity precision of the steel pipe structure pile.
本发明涉及深基坑支护的技术领域，公开了一种逆作法钢管结构桩旋挖钻进与全回转组合后插法定位方法，其特征在于，包括以下步骤：S10，安放长护筒；S20，使用旋挖机钻进成孔；S30，在桩孔内安放钢筋笼；S40，在桩孔内浇筑混凝土；S50，起吊钢管柱；S60，将钢管柱插入桩孔内，用全回转设备和万能平台两点一线的原理并实时监控所述钢管柱的垂直度，将钢管柱插入至设计标高；S70，浇筑钢管柱内混凝土；S80，拆除工具柱、回填碎石。本发明技术方案给出的逆作法钢管结构桩旋挖钻进与全回转组合后插法定位方法，能够保障钢管结构柱桩的垂直度精度。
