Novel prefabricated assembly type open caisson construction method for rapidly treating underground obstacles
The invention relates to a novel prefabricated assembly type open caisson construction method for rapidly treating underground obstacles. The novel prefabricated assembly type open caisson construction method comprises the following steps that a, construction preparation is conducted; step b, surveying and setting out; step c, excavating a primary sinking pit; d, the open caisson prefabricated pieces are spliced on site, and first section splicing of the prefabricated open caisson is completed; e, the working pit is backfilled after the first section of open caisson is assembled; f, earth is continuously excavated below the first section of the open caisson, and obstacles are broken and removed in the process; g, normal jacking is conducted, and lower treatment of the open caisson is completed; h, a cushion layer is poured at the bottom of the open caisson to seal the bottom; i, plain soil is backfilled and tamped in a layered mode, and ventilation treatment is conducted in the open caisson; and j, edge protection is conducted at the opening of the open caisson, and the process is completed. According to the construction method, a traditional cast-in-place technology is changed into factory prefabrication production and direct installation on site, the construction period can be effectively shortened, the influence on the site environment can be reduced, the pressure on urban traffic is relieved, and good benefits are brought.
本发明涉及新型预制装配式沉井快捷处理地下障碍物施工方法，包括以下步骤：步骤a、施工准备；步骤b、测量放线；步骤c、初沉坑开挖；步骤d、现场拼装沉井预制片，完成预制沉井的首节拼装；步骤e、首节沉井拼装完成后回填工作坑；步骤f、在位于首节沉井的下方继续挖土，并在此过程中破除障碍物；步骤g、正常顶进，完成沉井的下部处理；步骤h、在沉井的底部浇筑垫层封底；步骤i、素土分层回填夯实，并在沉井内做通风处理；步骤j、在沉井的开口处做临边防护，完成。该施工方法是将传统的现场浇筑工艺改成工厂化预制生产，现场直接安装，不仅能够有效缩短施工周期，还能够减少对现场环境的影响，减轻对城市交通的压力，带来较好的效益。
