Device and method for treating stuck drill of perforated pile

Abstract

The invention discloses a punched-pile drill blocking processing device. The drill blocking processing device comprises a chassis and a suspension arm. A winch support, a tray for containing a hammer and a suspension arm sliding rail are arranged on the chassis. A winch is arranged on the winch support. The suspension arm comprises two suspension-arm back sections and a suspension-arm front section, and a pulley is arranged at the front end of the suspension-arm front section. Two sliding blocks are arranged on the suspension arm sliding rail and are hinged to the two suspension-arm back sections respectively. The suspension-arm front section is hinged to two supporting frames, and the two supporting frames and the suspension arm form a tripod structure. A steel wire rope with scales on the winch penetrates through the pulley on the suspension arm and then is connected with the hammer. The projection of the hammer is located in a punched pile by adjusting the relative positions of the two sliding blocks and / or moving the two supporting frames. The invention further provides a punched-pile drill blocking processing method. By means of the drill blocking processing device and method, the problems that in the pile-foundation construction process, drill blocking occurs, and construction can not be normally carried out are solved, and smooth construction is guaranteed.

Description

technical field [0001] The invention belongs to the field of perforated pile construction, and in particular relates to a device and method for treating drill stuck in perforated piles. Background technique [0002] In construction engineering, pile foundation construction must be carried out at first, and percussion drilling rigs are usually used for hole forming operations in pile foundation construction. Its principle is: raise the percussion drill bit with edge angle and release it, rely on the impact force of its free fall to cut the strata below it, and use circulating mud to discharge debris to form holes. Due to geological, operational and other reasons, the percussion drill for drilling will get stuck, that is, the percussion drill bit of the percussion drill is stuck in the pile hole that has been drilled, and it can neither be lifted nor lowered. If it cannot be disposed of in time, it will be It will affect the pile-forming quality of the punched pile, reduce pr...
