(1) the device for preventing the lateral movement of the pile driver is arranged on a platform of the inclined pile driver, at the moment, a jacking oil cylinder in the device for preventing the lateral movement of the pile driver is in the maximum extension state, the lower end face of a pressure rod is separated from the construction ground, and the inclined pile driver can freely move.
(2) Paying off the pile position, and positioning the inclined pile machine;
(3) starting a hydraulic system, enabling a jacking oil cylinder to start to contract, and pressing a pressure rod with the oil cylinder until the pressure rod is inserted into the soil body for more than 2 meters;
(4) hoisting the inclined pile body on an inclined pile machine;
(5) the pile pressing system is started to press the inclined pile body into the soil body, the inclined pile body provides a horizontal thrust force for the inclined pile machine, the inclined pile machine moves along the horizontal direction, and the pressure rod in the pile machine side moving prevention device is inserted into the soil body to play a role in anchoring, so that the horizontal thrust force is resisted, and the horizontal movement of the inclined pile machine is prevented. And continuously pressing until the inclined pile body is pressed to the elevation.
(6) And (5) completing pile pressing, extending a jacking oil cylinder in the pile driving side shift prevention device, separating the lower end face of the pressure rod from the construction ground, and repeating the steps (2) - (5) to construct the next frame.
Compared with the prior art, the invention provides a device for preventing the lateral movement of a pile driver, which has the following advantages:
1. one side surface of the pressure rod is provided with a hole, so that the soil is automatically unloaded, and the resistance of the pressure rod to press down is reduced;
2. the pressure rod can be freely extended and retracted, so that the inclined pile machine can be conveniently and quickly moved, and the construction efficiency is improved;
3. the pressure rod in the device for preventing the lateral movement of the pile driver is inserted into the soil body, so that the anchoring effect is achieved, the operation is simple, and the horizontal displacement resistance of the inclined pile driver can be obviously improved.
