Ultralow-clearance spiral soil squeezing pile machine and construction method
The invention provides an ultralow-clearance spiral soil squeezing pile machine and a construction method, and belongs to the technical field of pile machines. The device comprises a chassis, a platform, a tower, a power head, a drill bit, a drill rod and the like, the power head comprises an upper power head and a lower power head which are respectively connected with the tower in a sliding manner; the upper power head is connected with a first lifting device, and the lower power head is connected with a second lifting device; the lower power head is provided with a lower holding device, and the upper power head is provided with an upper holding device. The drill rods or the drill bits are detachably connected. The height of equipment is reduced, the stability of the equipment is greatly improved, and safe production is ensured; the long spiral soil-squeezing cast-in-place pile is constructed in the mode of connecting and detaching the drill rod, the requirement for space is lowered, in the process of connecting and detaching the drill rod, it can be guaranteed that the drill bit continuously rotates underground, the phenomena of drill jamming and drill burying are avoided, connecting and detaching of the drill rod are safe and rapid, it can be guaranteed that pile forming is continuous, and the construction efficiency can be effectively guaranteed.
本发明提出了一种超低净空的螺旋挤土桩机及施工方法，属于桩机技术领域。其包括底盘、平台、塔架、动力头、钻头以及钻杆等；动力头包括分别与塔架滑动连接的上动力头和下动力头；上动力头连接有第一升降装置，下动力头连接有第二升降装置；下动力头具有下抱紧装置，上动力头具有上抱紧装置；钻杆与钻杆或钻头之间均采用可拆卸连接方式。本发明降低了设备的高度，大幅提升设备的稳定性，确保安全生产；通过接、拆钻杆的方式施工较长的螺旋挤土灌注桩，降低对空间的要求，并且在接、拆钻杆的过程中，能确保钻头在地下的持续转动而不至于出现卡钻、埋钻的现象，并且钻杆的接、拆安全快捷，能保证成桩连续，可有效保证施工效率。
