[0002] The ground-connected wall, also known as 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-cutting, anti-seepage, load-bearing and water-retaining structure.

[0003] At present, with the introduction of the concept of prefabricated buildings, prefabricated ground-anchored walls have begun to be used; however, when prefabricated ground-anchored walls are installed at the location of subway stations, the subway stations will need to have requirements on the ground height in the later stage, and often the upper end of the prefabricated ground-anchored walls will need to be broken, about 3-5 meters deep.
