Pile pulling construction method of pile pulling device

Abstract

The invention discloses a pile pulling device and a pile pulling construction method thereof. There are multiple groups of claws on the pile device which are driven by the oil cylinder and can protrude toward the center of the pipe to form a plurality of claws that support or cut off the waste piles. There are several alloy teeth on the inner surface of the claws. The solenoid valve and oil pipe are connected to the oil pump and oil tank on the combined power pile machine; there are multiple high-pressure water nozzles at the bottom of the sleeve type pile extractor, and the high-pressure water nozzles are connected to the combined power hole forming machine through the solenoid valve and high-pressure water pipe. The pile driver is connected with the water pump of the water source; the oil cylinder is also provided with a distance sensor for detecting the downward elongation of the piston rod, and the distance sensor is electrically connected with the controller. The convex column is accurate and reliable for the bottom of the waste pile, the construction noise is small, and the waste pile is pulled out after one-time rotation or cutting, saving time and effort, the construction period is short, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of waste pile cleaning, in particular to a pile pulling construction method of a pile pulling device. Background technique [0002] With the general promotion of urban expansion and renovation projects and the rise of urban rail transit construction, the cleaning of waste piles left after buildings were demolished in the 1980s and 1990s has become a technology that new high-rise buildings and urban rail transit must face. question. Generally, there are two situations: one is that the waste pile does not exceed 30 meters, and it can be pulled out at one time. The other is that although the waste pile is as long as 60 meters, it can meet the needs of rail transit construction, as long as the part above 30 meters is pulled out. At present, the commonly used method is to use destructive means such as hammering, rotary digging or twisting off the old pile foundation, and then clean up the remaining holes after ...

Problems solved by technology

At present, the commonly used method is to use destructive means such as hammering, rotary digging or twisting off the old pile foundation, and then clean up the remaining holes after destroying the waste pile body, which is time-consuming, laborious, long construction period, low construction efficiency, and large construction noise; or use The full casing adopts a clamp with spring control and other structures, which is clamped on the outer diameter of the waste pile after being penetrated to a certain depth, and then pulled upwards. However, it is difficult to control the clamping degree in actual operation, or the waste pile cannot be clamped to achieve the desired effect. The purpose of pulling out the whole waste pile is that the clamp is not tight enough to pull out the waste pile; or the full casing is used, and there are multiple sets of cutting components inside the full casing. After a certain depth, the cutting component is used to cut the waste pile first, and then the steel wire rope of the crane Manually fix the piles on the upper section to lift the waste piles out of the ground. This method has a lot of tool wear, many procedures, difficult operations for workers, low construction efficiency, and slow construction progress.

As far as the applicant knows, there is no ideal waste pile pulling device and method at present
