Building pile foundation construction method
The invention discloses a building pile foundation construction method. The building pile foundation construction method comprises the following steps of (P1) preparation before drilling, (P2) embedding of protecting barrels, (P3) grouting, (P4) hole drilling, (P5) hole cleaning and (P6) pile forming. According to the building pile foundation construction method, a rotary drilling rig and a percussion drill rig are used for drilling holes in a combined manner, the shortcoming in the existing single pile foundation construction technology is overcome, suitable drill rigs are selected according to different geological conditions, the building pile foundation construction method is not limited by the geological conditions, accidents of hole collapse, drill jamming and the like are avoided, and the quality of a pile foundation is ensured; and moreover, an operation rack is a stable support for the drill rigs, construction of the pile foundation is not affected by soil texture, site mud or raining, continuous construction of the pile foundation is guaranteed, the construction cost is reduced, and the construction efficiency is improved. The building pile foundation construction method is convenient to operate, high in construction speed and obvious in economic benefit; and materials are saved.
