Embodiment 1
[0066] A construction method for mechanical hole-forming cast-in-situ piles, specifically comprising the following steps:
[0067] (1) Preparatory work: Clear debris and then level the site. The size of the leveled site must be able to meet the construction position of the rotary drilling rig. The earthwork site is leveled and excavated directly to the bottom elevation of the raft cushion, and the measurement review is done and the data is recorded. filing;
[0068] (2) Stake out the pile position. According to the "principle from the whole to the local", the position of the pile foundation is set out. When setting out the elevation of the borehole, the elevation of the stakeout should be reviewed in time, and the total station is used to accurately stake out the height of each pile point. position, so that the error is within the specification requirements, the construction drilling rig needs the construction direction of the pile foundation of each building from inside to ou...
