摘　　要：北京燃气天津南港液化天然气(LNG)应急储备项目外输管道工程三标段在廊坊市安次区BA030+4~BA030+5桩穿越京沪京台联络线,顶管长度120m,顶管区域地质复杂,主要有人工填土和冲积地层,由上至下主要为粉土、粉质黏土、黏土、淤泥质粉质黏土、粉砂等。套管安装在地下9m位置,质量、安全风险高,工期紧,为保证业主2021年10月30日达到投产条件的要求,因此采用泥水平衡顶管方式穿越,使质量、安全、工期风险降到最低,保证顶管施工顺利进行。Beijing Gas Tianjin Nangang LNG Emergency Reserve Project External Pipeline Project Three Bid Section in Langfang City Anci District BA030+4-BA030+5 piles through the Beijing-Shanghai-Beijing-Taiwan liaison line,pipe jacking length of 120m,pipe jacking area geological complexity,mainly artificial filling and alluvial strata,from top to bottom mainly for silt,silty clay,clay,silt silty clay,silt,silt,etc. Casing is installed in the underground 9m position,high quality,safety risk,tight construction period,in order to ensure that the owner on October 30,2021 to meet the requirements of the production conditions,so the use of slurry water balance pipe jacking method through,so that the quality,safety,construction period risk to the minimum,to ensure the smooth construction of pipe jacking.
