[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described are only for explaining the present invention and are not intended to limit the present invention.
[0024] Normally, plain concrete underground continuous wall is to excavate a long and narrow deep groove on the ground with a groove forming machine. After forming a unit groove section, place a steel cage in the unit groove section, and then pour concrete to complete a unit wall section. , The unit wall sections are connected to each other in the form of I-steel, which is used for the hydraulic connection of diving and confined water inside and outside the retaining and partition pit.
[0025] The present invention proposes a method for constructing plain concrete underground continuous walls of deep foundation pits, in which the original plain concrete underground continuous walls 10...
