AI Technical Summary
Technical Problem
In the construction of bored piles, the location of unremoved anchor rods is unclear, and the anchor rod debris is difficult to clean, which leads to accelerated wear of the drill bit and damage to the hole wall, affecting the quality of the hole formation.
Method used
The anchor bolt location is determined by a detection device, the anchor bolt is broken by a pile driver, and the anchor bolt debris is cleaned up by a slag suction device. The cleaning efficiency is improved by combining mud replacement and magnetic suction.
Benefits of technology
Accurately determine the location of the anchor bolts and promptly clean up any debris to prevent drill bit wear and hole wall damage, thus ensuring the quality of the borehole.

Abstract
The present application relates to the technical field of drilling, and discloses a drilling cast-in-place pile construction system and method, the method comprising: detecting stratum data below a pile position, determining whether an anchor rod exists below the pile position according to the stratum data; when the anchor rod exists below the pile position, determining position information of the anchor rod; drilling and crushing the anchor rod according to the position information of the anchor rod; after the anchor rod is crushed into anchor rod slag, the pile machine is pulled out, a slag suction device is put into the hole, and a suction end of the slag suction device is located at the bottom of the hole; after the slag suction device completes the slag suction operation on the anchor rod slag at the bottom of the hole, the pile machine is drilled again to continue drilling. The present application can obtain accurate position information of each anchor rod by detecting each pile position, the anchor rod is crushed by drilling, and the anchor rod slag at the bottom of the hole is sucked out by the slag suction device, so that the crushed anchor rod slag can be cleaned out of the hole in time, and the anchor rod slag cannot cause the drill bit to wear faster and the hole wall to be damaged in the later drilling process.
