The site conditions of the project are complex, with densely distributed underground pipelines and intersecting roads, making construction organization relatively difficult. At the same time, the north side of the site is adjacent to the section between Xiju Station and Dongguantou Station of the existing Rail Transit Line 14, which imposes higher requirements on foundation pit deformation control and construction safety. The deepest part of the foundation pit reaches 23.5 meters, making it an ultra-deep foundation pit project with relatively high construction difficulty and technical requirements.
