[0035] 1) Level the site and clear underground obstacles to ensure that the site levelness meets the requirements for pile driver construction.
[0036] 2) Experimental construction: Before large-scale construction, a representative site should be selected for pile-forming process tests. During the test construction, construction parameters such as tamping energy, amount of crushed stones, filling coefficient and other construction parameters and the feasibility of pile sinking should be inspected.
[0037] 3) According to the foundation, pile diameter and pile length of the lot, select the appropriate mechanical equipment. A vibratory pile sinker can be used for transformation, with a winch, a gravity rammer, and a secondary feeding port.
[0038] 4) The pile driver is in place: the pile point 6 is placed on the pile position. When the pile driver is in place, the frame must be horizontal and stable, and the pile pipe is vertically aligned with the pile point.
[0039] 5) Vi...
