抚顺市某小区住宅,在施工锅炉房配套工程中,发现距锅炉房东北角桩基础外2米处,遇有一根φ400毫米上水铸铁管道,埋设深度为1.400米,为某厂正在送水的生产上水管道,全部为铅接口。见图1、2。设计考虑打桩时距管线太近,管子受振后管口裂开,造成停水、 In a residential building in the construction of a boiler house, a residential building in Fushun City was found to be 2 meters away from the base of the northeastern corner of the boiler house, and encountered a φ 400 mm cast iron water pipeline with a buried depth of 1.400 meters, which was used to produce water for a certain factory. The upper water pipelines are all lead interfaces. See Figures 1 and 2. The design considers that the pile is too close to the pipeline when it is piled, and the pipe is cracked after it is subjected to vibration, resulting in water stoppage.
