[0002] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water interception, anti-seepage, load-bearing and water retaining structure.
