Large-section slide-resistant pile square mechanical hole-forming construction method for soft and hard strata
The invention relates to the technical field of mechanical hole-forming construction methods, in particular to a square mechanical hole-forming construction method for a large-section slide-resistant pile in soft and hard stratum.The square mechanical hole-forming construction method comprises the steps that a rotary drilling rig drill rod and hydraulic power are utilized, a square excavation drill bit is designed and manufactured according to a slide-resistant pile square hole, and a top frame hydraulic motor connected with the drill rod and two excavation wheel fixing frames are manufactured; two excavation wheels are driven by two hydraulic motors, the hydraulic motors and two excavation wheel shafts rotate through gear tracks, scrapers are evenly arranged on the outer sides of the gear tracks, diamond heads are arranged on the peripheries of the excavation wheels, the diamond heads excavate rock soil during rotation, the front excavation wheel set and the rear excavation wheel set are fixedly connected through a transverse rod, and meanwhile it is guaranteed that the pile wall is smooth; compared with the prior art, the anti-slide pile continuous construction method has the advantages that the defects of high safety risk, long construction period and high cost are effectively overcome, the continuous construction of the anti-slide pile is effectively realized, the construction period is shortened, the construction quality and efficiency are improved, and the cost is reduced.
本发明涉及机械成孔施工方法技术领域，具体地说是一种用于软硬地层大断面抗滑桩方形机械成孔施工方法，利用旋挖钻机钻杆及液压动力，根据抗滑桩方孔设计制造方形开挖钻头，制作与钻杆连接顶架液压马达与两个开挖轮固定架，采用两个液压马达带动两个开挖轮，液压马达与两个开挖轮轴采用齿轮履带转动，齿轮履带外侧均匀布置刮刀，开挖轮外周布置金钢头，转动时金钢头开挖岩土，前后两组开挖轮采用横杆固定连接，同时保确桩壁光滑，方形钻头旋转开挖渣土采用圆形钻头进行出旋挖出渣，本发明同现有技术相比，本发明有效的克服了安全风险高，施工工期长，成本较大的缺点，有效实现了抗滑桩连续施工，节约了工期，提高了施工质量和效率，降低了成本。
