The construction process of underground continuous walls involves excavating machinery along the
peripheral axis of deep excavation projects. During the excavation, mud slurry is used to protect
the wall, and a narrow, long deep groove is first excavated. After completing the deep groove, it is
cleaned, and a steel reinforcement cage is placed inside. Using the conduit method, underwater concrete is poured to form a unit groove section. This process is then repeated, section by section, to construct a continuous reinforced concrete wall around the underground perimeter of the deep excavation site. This wall serves multiple purposes: bearing weight, cutting off water, and preventing seepage.
BJ Vibro possesses a wide range of underground continuous wall construction equipment, including various models of hydraulic grab trucks purchased from Bauer in Germany and Jintai in Shanghai. The company is also equipped with different types of impact drills and double-wheel milling machines, enabling it to undertake numerous underground continuous wall projects in fields such as water conservancy, electricity, industrial facilities, and civil construction.
