Pore-forming method of hard rock foundation pile with large diameter
The invention discloses a pore-forming method of a hard rock foundation pile with large diameter. The pore-forming method comprises the steps: step S10, locating and measuring a pile position, marking a pile number, arranging the spaces and the amount of drill holes according to the strength magnitude of each pile position in the rock, arranging the drill holes in according to a quincunx shape; step S20, performing hole arrangement construction according to the spaces and the amount of the drill holes; S30, rotationally excavating the rest of rocks until an end bearing pile is drilled into the preset depth to form a hole, and detecting the perpendicularity and the pile diameter of a pile body all the time in the pore-forming process, so as to ensure the quality of drilling; implementing hole cleaning operation in the pore-forming process so that the sediment thickness and dirt on a hole arm of the drilling bottom meet the quality requirements of a pile hole; step 40, installing a hole pile reinforcement cage, straightening main reinforcements of the reinforcement cage, and keeping the arrangement of the main reinforcement at uniform intervals; step 50, casting concrete after the pore-forming detection. Accoridng to the pore-forming method of the hard rock foundation pile provided by the invention, the rock breaking efficiency can be improved, the construction speed can be accelerated, the construction period can be saved, and the construction safety can be improved.
