Concrete pouring equipment for pile foundation construction

Abstract

The invention belongs to the technical field of pile foundation construction, particularly relates to concrete pouring equipment for pile foundation construction, and aims to solve the problems that an impurity-doped pile head needs to be cut off after a pile is formed due to the fact that the speed of concrete flowing into a pile bottom cannot be effectively controlled when a first tank of concrete is poured into a cast-in-place pile by existing concrete pouring equipment. According to the scheme, the device comprises an operation table, and positioning holes are formed in the operation table. According to the concrete pouring equipment for pile foundation construction, the pipe diameter of an outlet in the bottom end of the pouring guide pipe can be rapidly changed when a first tank of concrete is poured into a pile hole, so that under the condition that the volume of the concrete is fixed, the speed and pressure of a pile inlet hole filled with the concrete are changed; the contact area of wall protection slurry in a pile hole and a concrete pattern is reduced, the possibility of mutual doping of the slurry and concrete is reduced, the amount of pile head concrete needing to be cut off after the cast-in-place pile is solidified and formed is reduced, the construction speed is increased, and resource consumption is reduced.

Through the continuous adjustment of the three threaded rods 705, the pouring conduit 2 or the extension tube 3 on the supporting plate 701 is finally in a vertical state, and the annular locking piece 708 is loosened. Under the push of the reset spring 712, the rack 710 and the limit gear 707 resume the engaged state, and the threaded rod 705 no longer moves, and the pouring of concrete begins. In the process of pouring the first tank of concrete, after the isolation ball is pushed out of the pouring conduit 2 by the concrete, the drive motor 509 is started, and the drive motor 509 drives the inner gear ring 512 meshing with the drive gear 510 to rotate. The rotating frame 506 rotates and causes the arc groove 507 to push the slider 504 connected to the short shaft 505 to move outward in the movable groove 503, and the connecting rod 517 connected to the slider 504 rotates at the support position point as the connecting rod 517 moves, and the fixed block 522 connected to the end of the rotating rod 518 away from the connecting rod 517 drives the movable block 521 to slide on the strip opening 520, so that the adjusting plate 1 515 presses the adjusting plate 2 516 to overcome the torsion force of the torsion spring 524 and gather toward the axis of the casting conduit 2, thereby shrinking the diameter of the casting conduit 2, accelerating the flow rate of the concrete flowing out of the casting conduit 2, and quickly filling it into the bottom of the pile hole, and then continuing to pour concrete until the entire pile hole is poured.
