From January to July 2013, the PetroChina Pipeline Bureau Crossing Company successively crossed the Daliao River on the Yingpan Link Line (pipe diameter 711 mm, length 2480 m), and the Hubao E Product Pipeline crossing the Yellow River (pipe diameter 355.6 mm, length 3200 m) , Jiangdu-Rudong natural gas pipeline crosses the Yangtze River three times (pipe diameters 711 and 406.4 mm, length 3303 meters) and Guangdong Yamen Waterway Directional Drilling Crossing (pipe diameter 1016 mm, length 2700 meters) has set five consecutive world records. This is an important sign that my country’s directional drilling crossing technology and construction capabilities have reached world level.
At 6:38 on July 31, 2013, the Pipeline Bureau Crossing Company successfully pulled back in the directional drilling and crossing project of the Yamen Waterway Phase II Project of the Guangdong Natural Gas Pipeline Network, and created a large diameter of 1016 mm and a length of 2700 meters. The world record for horizontal directional drilling of pipe diameters, long distances, and complex formations. The project is located in the Huangmao sea area of the Pearl River water system at the junction of Zhuhai and Jiangmen. The strata passing through are mainly fully weathered granite, gravel sand and residual soil layer. The geological soft and hard are interlaced. It is extremely complex, difficult to cross, and high in construction risk.
