Mechanical light nail thorn anchoring pile and construction method
The invention discloses a mechanical light nail thorn anchoring pile and a construction method. The anchoring pile comprises an anchoring pile body, a pile cap arranged at the upper end of the anchoring pile body, a pile shoe arranged at the lower end of the anchoring pile body, a drilling mechanism arranged at the bottom of the pile shoe and an impact pile. The anchoring pile body comprises an outer pipe and an inner pipe which is arranged on the inner side of the outer pipe and can be separated under the action of radial pressure, a plurality of nail thorns are distributed on the outer wall of the inner pipe, and a plurality of holes matched with the nail thorns are formed in the outer pipe. The inner pipe is formed by splicing a plurality of pipe pieces, the inner pipe expands outwards in the radial direction after the impact pile is driven in, and nails on the outer wall of the inner pipe penetrate through the holes to be unfolded. The nail thorns on the inner pipe penetrate into the rock stratum of the soil layer to form the uplift bearing capacity, the uplift bearing capacity can be rapidly formed under the non-grouting working condition, the uplift bearing capacity can be used after the light anchoring pile is driven into the soil layer on site, and the requirements for rapid emergency repair and emergency rescue are met.
本发明公开了一种机械式轻型钉刺锚固桩及施工方法。本发明的锚固桩包括锚固桩本体、设置于所述锚固桩本体上端的桩帽、设置于锚固桩本体下端的桩靴、设置于所述桩靴底部的钻孔机构以及冲击桩；所述锚固桩本体包括外管以及设置于所述外管内侧的可在径向压力作用下分开的内管，所述内管的外壁分布有若干钉刺，所述外管上设置有与所述钉刺相配合的若干孔洞；所述内管由若干块管片拼接而成，所述内管在冲击桩打入后，沿着径向向外扩张膨胀，内管外壁上的钉刺穿过孔洞展开。本发明通过内管上的钉刺刺入土层岩层形成抗拔承载力，能使其在非灌浆的工况下快速形成抗拔承载力，通过轻型锚固桩现场打入，即可使用，满足快速抢修应急抢险的要求。
