摘要
近些年经济发展进入快车道,工程建设项目数量增量较大,各项施工工艺得到了广泛的运用,总结了宝贵的实践经验。其中,沉井施工工艺在供水管网、雨污水、污水处理厂等工程中得到了广泛的运用及发展,积累了大量的成熟经验。论文以洋北污水处理厂WS14污水井沉井施工工艺为例,进行探讨。对施工过程中测量控制、垫层施工、沉井制作、沉井下沉、沉井封底按照施工顺序进行了工艺说明。对沉井施工过程中的控制重点,如井位纠偏、沉井不沉余方措施及处理方法、流砂预防及处理措施、沉井制作的质量控制、沉井下沉的质量控制进行了详细说明。
In recent years,economic development has entered the fast lane,and the number of engineering construction projects has increased significantly.Various construction techniques have been widely used,and valuable practical experience has been summarized.Among them,the construction technology of sunken wells has been widely used and developed in water supply networks,rainwater and sewage treatment plants,and other projects,accumulating a large amount of mature experience.This paper takes the construction process of WS14 sewage well sinking in Yangbei Sewage Treatment Plant as an example to explore.Process instructions were provided for measurement control,cushion construction,caisson fabrication,caisson sinking,and caisson bottom sealing during the construction process in accordance with the construction sequence.Finally,a detailed explanation was provided on the key control points during the construction process of the caisson,such as deviation correction of the well position,measures and treatment methods for non sinking of the caisson,prevention and treatment measures for sand flow,quality control of caisson production,and quality control of caisson sinking.
