Background
At present, in the urbanization process, more and more high-rise residential buildings are used. However, due to the limited land resources of cities, the old buildings are often dismantled and the existing underground engineering piles such as concrete piles are pulled out when the cities are rebuilt at present or in the future. The basic principle of the existing pile pulling technology and special equipment is to destroy the extrusion force of the geology around the pile foundation to the pile, loosen the soil around the pile, reduce the friction force of the soil to the pile, and then use corresponding hoisting machinery to hoist and pull. The main method comprises the following steps: 1) a vibration pile sinking and extracting machine. A vibration pile-sinking and drawing machine is a pile-drawing construction device which is used in construction and foundation engineering. Periodic exciting force is generated through a hydraulic device and the eccentric block, so that the soil layer around the pile is damaged. 2) And (5) impacting to form a hole and pull the pile. The impact hole-forming pile-pulling method adopts a hollow impact hammer impact drilling slurry wall-protecting process, uses a hollow impact hammer with the diameter larger than the outer diameter of a pipe pile to impact drill along the pipe pile, the pipe pile plays the role of a guide rod, and washes away soil around the pile under the cooperation of slurry, so that the friction resistance is reduced, and finally, a crane is adopted to lift out the prestressed pipe pile. 3) And (5) pulling the pile by using the steel sleeve. Pile pulling by using a steel sleeve is the most common pile pulling process at present. The pile pulling process includes driving or pressing steel sleeve, reducing the friction resistance of pile pulling, and final pulling pile with crane.
The prior patent grant publication number: CN101392532B discloses a hydraulic pile extractor device, which comprises five parts, namely an anchor seat assembly, an oil cylinder, a bottom cone, an upper guard plate and a lower guard plate; the anchor seat assembly comprises a top cover plate, a wedge block and an anchor seat. The oil cylinder is connected with the bottom of the anchor seat through a double-lug-ring spherical hinge. The bottom cone is also connected with the other end of the oil cylinder through a spherical hinge through a double-lug ring.
