Stable anchor group static pile pressing structure and anchor group static pile pressing method

Abstract

The invention provides a stable anchor group static pile pressing structure. The stable anchor group static pile pressing structure comprises a plurality of pile pressing holes formed in the ground and a pile pressing device used for pressing piles. Longitudinal beams are arranged on the periphery of the pile pressing holes. Cross beams are arranged above the longitudinal beams. The cross beams and the longitudinal beams are crossed to form network grids. The pile pressing holes are located in the network grids. The pile pressing device is arranged between the cross beams. Counterweight vehicles capable of moving along the cross beams are arranged on the cross beams. The counterweight vehicles and / or the cross beams are provided with locking structures. The counterweight vehicles can be locked at the designated locations of the cross beams through the locking structures. An anchor group static pile pressing method comprises the steps of beam erection, specifically, erecting the longitudinal beams and the cross beams on the periphery of the pile pressing holes in a crossed mode to form the network grids, wherein the pile pressing holes are located in the network grids; counterweightvehicle installation, specifically, installing the counterweight vehicles capable of moving along the cross beams on the cross beams and adjusting the weight of the counterweight vehicles according to the counterweight requirement; and pile pressing, specifically, moving the counterweight vehicles to the designated locations, locking the counterweight vehicles, installing the pile pressing deviceand starting pile pressing.

Description

technical field [0001] The invention relates to the field of building reinforcement, in particular to a stable group anchor static pressure pile structure and a group anchor static pressure pile method. Background technique [0002] At present, the existing static pressure pile structure is shown in Chinese patent CN2011202813501, which mainly discloses the group anchor static pressure pile structure, including pile pressure holes, beams, and longitudinal beams on the ground, and expansion bolts are planted on the ground, and the expansion bolts The head is fixed with a connecting lug through a nut, and the connecting lug presses the beam and the longitudinal beam on the ground; the beam is provided with a pile-pressing device, and the jack on the pile-pressing device contacts the pile head in the pile-pressing hole . [0003] The defect of the prior art is that: when the jack applies a positive force to the pile head to press the pile, the pile head transmits a reverse for...

AI Technical Summary

Problems solved by technology

[0003] The defect of the prior art is that: when the jack applies a positive force to the pile head to press the pile, the pile head transmits a reverse force to the jack, and the reverse force needs to be offset by a support force, otherwise the beam and longitudinal beam will be lifted off the ground

In the above group anchor static pressure pile structure, the support force is provided by the expansion bolts, and the transmission path of the support force is: ground, expansion bolts, connecting lugs, longitudinal beams, beams, and jacks. It can be seen that the support must be provided There are high standards for the tightness of the connection between the ground and the expansion bolts, the rigidity of the connecting lugs, and the tightness of the connection between the connecting lugs and the beam, and the construction site is inside a building, which is limited by the height of the floor Due to environmental factors such as ground material and ground material, it is difficult to meet the above-mentioned requirements and standards, which leads to the fact that the expansion bolts are prone to break away from the ground, the connecting lugs are broken, and the beam and the connecting lugs are disengaged during the construction process. Continue to provide support for the jack, and the jack cannot press the pile head
