Fixing Method of Anchor Static Pressure Pile Machine Base

Abstract

The invention discloses a fixing method for a base of a pile driver for a static-pressed pile by anchor rods. The fixing method includes the following steps that S1, a fixing device is manufactured, and the device comprises a steel plate, a plurality of anchors, a plurality of sleeves and the anchor rods matched with the sleeves; S2, before concrete pouring, the face, with the anchors, of the device is made to face downwards and is pre-embedded in the position above a pipe pile reserved hole, and then all through holes in the steel plate are sealed temporarily; S3, concrete is poured; S4, temporary sealing is removed completely, and the anchor rods are mounted in the sleeves; S5, the base of a pile driver body is mounted on the anchor rods through anchor rod holes in the base; S6, the driver body is mounted on the base, and pile pressing is carried out; S7, after pile pressing is completed, nuts are dismounted, and the anchor rods are recovered; and S8, end sealing ribs are distributed between the two sets of through holes. Through the fixing method, the positioning precision of the anchor rods can be ensured, the centers of the two sets of anchor rods are made to coincide with the centers of the pipe pile reserved hole, and it is ensured that a pipe pile is smoothly pressed into the pipe pile reserved hole.

Description

technical field [0001] The invention relates to an anchor static pressure pile, in particular to a method for fixing the base of an anchor static pressure pile machine. Background technique [0002] With the continuous development of the construction industry, the anchor static pressure pile is more and more used in high-rise buildings because of its simple structure, safety and reliability. At present, in the construction process of anchor static pressure pile pile machine base, two sets of anchor bars are usually pre-embedded in the concrete first, and the upper ends of the anchor bars protrude from the concrete surface, and then the body of the pile machine is installed on the two sets of anchor bars , and then press the pile. After the pile is completed, the exposed part needs to be cut off, and finally the head reinforcement is arranged to seal the pile head, but this will have the following problems: First, the anchor rod is pre-buried in the concrete alone, and the po...

Problems solved by technology

At present, in the construction process of anchor static pressure pile pile machine base, two sets of anchor bars are usually pre-embedded in the concrete first, and the upper ends of the anchor bars protrude from the concrete surface, and then the body of the pile machine is installed on the two sets of anchor bars , and then press the pile. After the pile is completed, the exposed part needs to be cut off, and finally the head reinforcement is arranged to seal the pile head, but this will have the following problems: First, the anchor rod is pre-buried in the concrete alone, and the positioning accuracy is difficult to guarantee, resulting in two The center of the group anchor rod does not coincide with the center of the reserved hole of the pipe pile, so that the pipe pile cannot be pressed into the reserved hole of the pipe pile; secondly, the exposed part of the anchor rod affects the ground traffic and poses a safety hazard, and it is also easy to be hit by ground objects, resulting in The anchor itself and the upper end of the thread were severely damaged, making it impossible to install the pile driver; thirdly, the exposed part of the anchor had to be cut off after the pile was completed, resulting in an increase in material and labor costs; Adopt electric welding, increase cost
