8. The construction method for vertically positioning the silt geological pile foundation according to claim 1, wherein in the step S11, the pile foundation is manually rotated and pushed to adjust the position of the pile foundation, and the method specifically comprises the following steps:
s111: installing an indicator light on the side wall of the pile foundation;
s112: the constructor pulls the pile foundation control line to carry out rotary pulling treatment on the pile foundation;
s113: judging whether the pile foundation is aligned with the pile hammer, and stopping adjustment when the indicator light on the side wall of the pile foundation is fully on and indicates that the pile foundation is aligned with the pile hammer; when the indicator light on the side wall of the pile foundation is partially not bright, the pile foundation is not aligned with the pile hammer, and the step S112 is repeated;
the indicating lamp comprises a first indicating lamp, a second indicating lamp, a third indicating lamp and a fourth indicating lamp, the first indicating lamp is electrically connected with the first laser receiver, the second indicating lamp is electrically connected with the second laser receiver, the third indicating lamp is electrically connected with the third laser receiver, and the fourth indicating lamp is electrically connected with the fourth laser receiver.
9. The construction method for vertically positioning the sludge geological pile foundation according to claim 8, wherein in the step S13, whether the pile foundation is inclined or not is judged, and the method specifically comprises the following steps:
s131: the second edge verticality positioning device and the second center verticality positioning device emit laser signals;
s132: judging whether the first edge verticality positioning device, the first center verticality positioning device and the laser positioning plate receive laser signals or not, if so, fully lighting an indicator lamp on the side wall of the pile foundation to indicate that the pile foundation is not inclined, and finishing the judgment; if the laser signal is not received, the indicator lights on the side wall of the pile foundation are all on or part of the indicator lights are not on, and step S133 is executed;
s133: and observing the direction and distance from the laser emitted by the second central verticality positioning device to the first central verticality positioning device on the laser positioning plate according to a display device, and adjusting the position of the pile foundation to enable the pile foundation to be vertical again.
10. The construction method for vertically positioning the sludge geological pile foundation according to the claim 1, wherein the second threshold value is 6m to 10m in the step S14.
