A preliminary understanding of the general situation of the construction site is made to determine the location of equipment stacking. When the pile machine comes into the field, it is necessary to check whether the accessories for the access equipment are complete. After the basic preparation work is started, the assembly is started, and the following parts are checked.
(1) to study and master the basic information of the field, and to erect construction enclosure and related warning signs around the operating area.
(2) reasonable determination of the position of piling machine equipment
According to the situation, first of all to stay away from the pond, mud pit, high-voltage wire, soft soil and surrounding buildings; according to the construction organization design is chosen in the pile near the first pile dock construction.
(3) clean assembly site obstacles, leveling, laying pad or sleeper expanding pile machine bearing area should not be less than 35kPa when necessary; the bearing capacity of the pile foundation of large tonnage machine parking site average.
(4) inspection equipment parts and auxiliary equipment construction is complete, such as weight, pipe, concrete mixer, ash (mud) pump, electric welding machine, testing equipment and so on, before construction should be checked according to the corresponding technical specifications for safety standards, the location should be convenient for construction management.
(5) rationally arrange the position and direction of electric control line laying, shorten the distance between the piling machine and the distribution (box) cabinet as far as possible, and reduce the power loss of the line. In one case, the distance between the operation point (pile position) and the power supply point is controlled within 200m. The starting voltage drop of Wuhan Wuhan piling machine assembly safety technology is not greater than the rated voltage 10%.
(6) non - assembly personnel should stay away from the equipment assembly site.
