Taking an example from Zhong-Wu Lang Ping Valley Gas Pipeline Project, we combined the engineering geological of the site area, and learn from experience in similar projects. Then, on this basis, we carried out the design of the immersed work, introduced the applications of the immersed controlled excavation work. The results show that the immersed controlled excavation work achieved the expected results. Practice shows that the controlled excavation construction not only prevent gravity retaining wall concrete construction disturbance and construction personnel devastation, but also improved the depth of pipeline settlement (original design maximum settlement increased to -1.5m from -1.0m.). The program for Zhong-Wu Lang Ping Valley Gas Pipeline engineering success, and can providing guidance for other similar pipeline project.
