2012年3月11日,西气东输二线东段上海支线最后一项控制性工程——蔡东潘故居定向钻穿越一次回拖成功,为上海支线全线贯通提供了保障。蔡东潘故居穿越工程,穿越实长547.3m,管道直径1016mm,通过的主要地层为淤泥质黏土和强风化熔结凝灰岩。尽管穿越距离不长,地质也不复杂,但施工难度大。现场作业带周边环境特殊,水平方向上左侧是省级文物保护单位蔡东潘故居,右侧是高速公路,垂直方向上钻机位置处在山顶,穿越曲线稍低会进入
On March 11, 2012, the last controlled project of the Shanghai branch of the eastern section of the second West-East Gas Pipeline - the successful retrofitting of directional drilling at the former residence of Cai Dong-Pan-succeeded in providing support for the entire extension of the Shanghai sub-district. The former residence of Cai Dong-pan passes through the project with a length of 547.3 m and a pipe diameter of 1016 mm. The main strata passing through are silt clay and strong weathered melted tuff. Although the traversing distance is not long and the geology is not complicated, it is difficult to construct. Site work with special surrounding environment, the left side of the horizontal direction is the provincial cultural relics protection units Cai Dong Pan former home, the right is the highway, the vertical drilling rig location at the top of the mountain, through the curve is slightly lower will enter
