摘　　要：深基坑对工程安全及造价有较大影响,如何根据具体条件正确地选择施工方法,是保证施工安全与质量及降低工程造价的关键。仪征污水处理工程进水泵房施工采用了深井和轻型井点同时降水,水泥搅拌桩围护与止水,基坑放坡开挖的施工方法,确保了本工程安全地实施。同时与一般基坑围护施工方法相比,降低了基坑工程造价的50%。The deep pit has the great influence on the engineering safety and construction cost. How to select the correct construction method on the detail conditions is the key to ensure the construction safety and quality, and reduce the engineering construction cost. In the construction of the inlet pump house of Yizheng Wastewater Treatment Plant, the construction methods are used, which are the deep well and light well simultaneously to lower water, the protection of the cement mixing piles, stop water and pit sloping and excavation so as to ensure the safe implementation of this project. Compared with the usual construction methods of pit protection, the construction cost of pit can be reduced to 50%.
