Rectifying and repair structure for inclined pile foundation

Abstract

The invention discloses a rectifying and repair structure for an inclined pile foundation, applies to the field of pile foundation repair, and solves the technical problem of complicated operation ofthe pile foundation repair. According to the technical scheme, the rectifying and repair structure for the inclined pile foundation comprises a positioning device, wherein the positioning device comprises a front positioning plate and two side positioning plates in sliding connection with the front positioning plate, and a locking mechanism is arranged between each side positioning plate and the front positioning plate; a straightening device is connected with one side of the positioning device and comprises a hydraulic jack connected with the front positioning plate, the hydraulic jack comprises a cylinder body and a telescopic push rod, and a push plate is connected onto the telescopic push rod; a flow guiding groove allowing slurry to circulate is formed in one side, opposite to the telescopic push rod, of the push plate. The rectifying and repair structure for the inclined pile foundation has technical effect that for operators, the repair work of the pile foundation is simple andeasy to operate.

Description

technical field [0001] The invention relates to the technical field of pile foundation structure repair, in particular to a deviation correction repair structure for inclined pile foundations. Background technique [0002] Due to the complex geological conditions or the disturbance of construction machinery, the side slope soil of the foundation pit is squeezed into the foundation pit, which easily causes the deflection of the pile foundation. If the deflected pile foundations are not treated, large-scale pile repairs will have to be carried out. In some projects, due to the limitation of the construction site and the short distance between the pile foundations, it is difficult to implement large-scale pile repairs. Pile foundation rectification and reinforcement. [0003] The publication number is CN103243745A "The Correction Method of Prestressed Concrete Pipe Pile Foundation", which uses a large excavator to pull the pipe pile, and uses a jack to push the pipe pile in th...

[0002] Due to the complex geological conditions or the disturbance of construction machinery, the side slope soil of the foundation pit is squeezed into the foundation pit, which easily causes the deflection of the pile foundation

If the deflected pile foundations are not treated, large-scale pile repairs will have to be carried out. In some projects, due to the limitation of the construction site and the short distance between the pile foundations, it is difficult to implement large-scale pile repairs. Pile foundation correction and reinforcement

[0003] The publication number is CN103243745A "The Correction Method of Prestressed Concrete Pipe Pile Foundation", which uses a large excavator to pull the pipe pile, and uses a jack to push the pipe pile in the return hole, so that the pipe pile returns to the design pile position; Straightening, when the horizontal load is too large, it is easy to cause damage to the pile body. The reaction point of the horizontal load is limited by the site conditions. How much thrust is applied during the restoration of the pile foundation depends on the feeling of the construction personnel. Correction method of the foundation" requires the use of a large excavator, some small foundation pits cannot park a large excavator, and even the movement of a large excavator may deflect the pile foundation that was not originally deflected, causing inconvenience in actual construction
