Static pressure construction method of prefabricated reinforced concrete pile
The invention discloses a static pressure construction method of a prefabricated reinforced concrete pile. The static pressure construction method comprises the following steps: the preparation is performed before the construction; a pile machine is in place, and piling mechanical equipment, a lifting machine and a pressure gauge are checked; a prefabricated pile is lifted, a portal support oil cylinder is started, and a portal is slightly inclined by 15 degrees; the pile is stabilized, after the tip of the pile is inserted into a pile position, a pile press oil cylinder is slightly started , when the pile is inserted into the soil by 50 cm, the verticality of the pile and the horizontality of a platform are corrected again, the pile press oil cylinder is started again, the pile is slowly pressed down, and the construction speed is controlled within 2 m/m; when the pile pressure reaches two times of designed load, or the top of the pile reaches a supporting layer, the pressure can be stabilized at any time; the pile is pressed, a special person is dispatched or automatic recording equipment is started in construction to perform the pile sinking construction recording; the pile is received and sent; and the inspection, the lifting, the carrying and the stacking are performed. Compared with the hammering, the static pile loading has such advantages as no noise, no vibration, no pollution and safety.
