Treatment method for underground pipeline in urban pile foundation construction
The invention is applicable to the technical field of urban buildings, and provides a treatment method for an underground pipeline in urban pile foundation construction. The treatment method comprisesthe following steps that S1, a cement pipe with the inner diameter larger than the designed diameter of a pile foundation is selected as a pile casing, and one end of the cement pipe is drilled to achieve a hoisting hole; S2, a drill bit is used for drilling at a designed pile position, and the drilling depth reaches 0.9m-1.1m below the bottom of the pipeline; and S3, the cement pipe is lowered into a drilled deep hole in a segmented mode through manual operation matched with a drilling machine or a truck crane. Enough pile foundation operation space is achieved, the drilling hole blocking effect can be sufficiently guaranteed, the phenomenon that the pile is not fully filled in the pile filling process is prevented, concrete waste is avoided, manual operation down into the pipeline is not needed, personal safety is protected, the manufacturing cost is low, the machining period of the long pipe casing is short, and engineering construction is facilitated.
本发明适用于城市建筑技术领域，提供了一种城市桩基施工遇地下管线的处理方法，包括以下步骤：S1、选用内径比桩基设计直径大的水泥管作为护筒，并且对水泥管一端进行打眼工作，作为吊装孔；S2、通过使用钻头在设计桩位上，进行钻进，并且钻进的深度至管道底部一下0.9m‑1.1m；S3、然后通过人工配合钻机或汽车吊，将水泥管分节下放至钻进的深孔中。有足够的桩基作业空间，而且钻孔堵塞效果可以得到充足的保证，而且灌桩时不会出现“灌不满”的现象，避免造成混凝土浪费，再者不需要人员下到管道里作业，保障了人身安全，造价成本较低，而且长护筒加工周期短，有利于工程施工。
