Construction method for quick well completion in quicksand geology
The invention provides a construction method for quick well completion in quicksand geology, and belongs to the technical field of dewatering well construction.The construction method for quick well completion in quicksand geology comprises the following steps that according to construction requirements, a total station or a GPS is used for conducting well hole positioning, well number compiling, elevation measuring and well completion depth calculating, and a steel protection wall with the proper length is selected; the conical base is placed at the position of a well point, the position of the conical base is fixed, the steel retaining wall is lifted through a pile driver and perpendicularly placed on the conical base, the center lines of the steel retaining wall and the conical base coincide, and then the steel retaining wall is perpendicularly corrected by adjusting the position of the pile driver and large and small beam arms. According to the construction method for rapid well completion in the quicksand geology, a protection wall made of a steel material is adopted to replace a traditional mud protection wall well completion mode, so that the well diameter is controllable, the well completion quality is improved, and hole collapse is prevented; meanwhile, mud in the well is prevented from polluting the environment, the hydraulic pile driver is adopted for hole forming, the number of used machines is small, movement is convenient, construction is flexible, well forming is rapid, and the construction period is short.
本发明提供一种流砂地质快速成井的施工方法，属于降水井施工技术领域，该流砂地质快速成井的施工方法包括以下步骤：根据施工需要，利用全站仪或GPS进行井孔定位，编制井号并测量高程计算成井深度，选用合适长度的钢护壁；将锥形底座放置在井点位置上，使其位置固定，用打桩机将钢护壁吊起并垂直放置在锥形底座上，使二者中心线重合，然后通过调整打桩机位置及大小梁臂对钢护壁进行垂直校正。该流砂地质快速成井的施工方法，采用钢质材料的护壁，代替传统泥浆护壁成井方式，使得井径可控，提高成井质量，防止塌孔；同时避免井内泥浆污染环境，采用液压打桩机成孔，使用机械少，移动方便，施工比较灵活，成井快速，施工周期短。
