Construction method for existing basement pile foundation with high water level
The invention belongs to the field of basement structure demolition and renovation, and particularly relates to a construction method for a basement pile foundation with high water level. The construction method sequentially comprises the following steps of pre-construction preparation, floor reinforcement, hole opening, sleeve placement, pile forming construction and sleeve recovery. The method has at least the following advantages that a water drill is adopted to opening holes for floor opening, so that the noise pollution and the dust pollution are reduced; a sleeve is used for drainage, sothat the pollution generated by mud to an existing basement structure in the traditional pile repairing construction is avoided; mud generated by the pile repairing construction is treated through amud-water separation system and then transported out of a factory, so that the treatment efficiency is improved, and the pollution to the environment is reduced; generated construction waste is smalland is treated in a centralized clearing and transportation mode, so that the cleanliness of a construction site is guaranteed; and continuous precipitation is avoided, underground water resources areprotected, and the influence on the surrounding environment is reduced at the same time.
本发明属于地下室结构拆改领域，具体涉及一种高水位既有地下室桩基施工工法。所述施工工法依次包括以下步骤：施工前准备步骤、楼板加固步骤、开孔步骤、套筒放置步骤、成桩施工步骤和回收套筒步骤。本发明公开的方法至少具有以下优点：楼板开孔采用水钻开孔，降低了噪音污染及扬尘污染；使用套筒引流，避免了传统补桩施工中泥浆对既有地下室结构产生的污染；补桩施工产生的泥浆通过泥水分离系统处理再运出厂，提高了处理效率并减少对环境的污染；产生的建筑垃圾较少，并通过集中清运的方式进行处理，保证施工现场的整洁；避免持续降水，保护地下水资源，同时降低对周边环境的影响。
