Existing building forced landing deviation rectifying method based on horizontal directional drilling
The invention provides an existing building forced landing deviation rectifying method based on horizontal directional drilling. The method comprises the following steps that the deviation rectifying amount of a building is determined according to the inclination condition of the building, and the positions and the number of deviation rectifying holes are preliminarily designed; working pits are formed in the two ends of the side, with small settlement, of the building, guide holes are drilled under the building foundation through a horizontal directional drill according to the positions and the number of the designed deviation rectifying holes, and a deviation rectifying hole path can be formed under the building foundation; after drilling of the guide hole is completed, the guide drill bit is detached in time, a reamer is arranged for reaming till the hole diameter of the deviation rectifying hole meeting the design requirement is reached, and hole cleaning operation is conducted one time or multiple times after the deviation rectifying hole is formed through reaming; compared with the prior art, the method has the following beneficial effects that the horizontal directional drilling machine and the direction control instrument are adopted, drilling and soil taking are directly conducted on the foundation bottom of the existing building, so that the deviation rectifying purpose is achieved, and safe and effective deviation rectifying of the existing building is achieved under the condition that a conventional forced landing deviation rectifying method cannot be implemented.
本发明提供一种基于水平定向钻的既有建筑迫降纠偏方法，包括以下步骤：根据建筑物的倾斜情况确定建筑物的纠偏量和初步设计纠偏孔的位置和数量；在建筑物沉降较小侧的两端设置工作坑，并根据设计好的纠偏孔的位置和数量采用水平定向钻在建筑物基础下进行导向孔钻孔，可在建筑物基础下形成纠偏孔路径；导向孔钻孔完成后及时卸下导向钻头，并换上扩孔器进行扩孔，直至扩至设计要求达到的纠偏孔孔径，扩孔形成纠偏孔后进行一次或多次清孔作业；本发明具有以下有益效果：本发明采用水平定向钻机和控向仪器，在既有建筑基础底直接钻孔取土，从而实现纠偏的目的，在常规迫降纠偏方法无法实施的情况下实现对既有建筑物的安全有效纠偏。
