Embodiment 1
[0027] Such as Figure 1-2 As shown, a construction method for controlling the direction and verticality of the column pile buried in the soil comprises the following steps:
[0028] 1. Locate the pile position on the hardened concrete floor 7, release the direction control line 11 near the pile position, place two tripods 13 on the control line of theodolite 16, and pass the centering rod 15 on the two tripods 13 through the line The rope 14 is connected, and the centering rod 15 on one tripod in the two tripods 13 is arranged on the control line 11;
[0029] 2. Set the pile site, use the rotary excavator to align the pile hole 12 on the concrete floor 7 to be built, use the truck crane to lift the pile driver, align the drill bit of the pile driver with the pile hole 12, and check the levelness of the pile frame , vertical correction, the pile driver and the pile driver drill bit are installed to meet the requirements and drill the pile hole. After the drilling is completed...

The invention relates to a construction method for controlling the direction and perpendicularity of a vertical column pile embedded in soil. The construction method comprises the following steps that a pile is positioned, and surveying and setting out as well as axis controlling are conducted; a pile position opening is excavated mechanically, and hole forming and cleaning are conducted; a reinforcement cage is placed; spacer bars and a clinometer are mounted on the top of a steel vertical column; the steel vertical column is lifted and falls to a designed elevation; according to the distance from the two ends of a horizontal rebar to a control line and the numerical value of the clinometer, the steel vertical column is adjusted to a designed direction and subjected to perpendicularity rectifying through a pile driver and falls to the designed elevation; the spacer bars are detached; a guiding pipe is placed for hole cleaning; and concrete is poured. By mounting the spacer bars and the clinometer on the top of the steel vertical column, the direction and perpendicularity of the steel vertical column are controlled, so that the construction accuracy of the direction and perpendicularity of the vertical column pile are improved greatly, it is guaranteed that in the later period of supporting construction, the steel vertical column is parallel to a supporting beam so as to be in favor of welding of anchor rebars, and accordingly the structural construction quality is improved greatly.
Description
technical field [0001] The invention belongs to the technical field of column pile construction, in particular to a construction method for controlling the direction and verticality of column piles buried in soil. Background technique [0002] The diversification of building functions and the very limited site space lead to more and more deep foundation pit projects. The supporting enclosure works are particularly important. In the existing construction technology, it is difficult to control the direction and verticality of the steel column during the construction of the column pile, resulting in the difficulty of welding the anchoring steel bars in the later construction of the support beam, the structural integrity is not good, and the structural force requirements cannot be met, and the structural safety is reduced. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for controlling the d...
