1) The clear distance between the two tunnels in Huhuang shield section of Shenzhen Metro Line 2 East extension line is 1.71m-2.0m, and the vault buried depth is about 14m.Within the scope of overlapping tunnels, the stratum is mainly quaternary new artificial filling soil, alluvial proluvial cohesive soil layer, sand gravel layer and residual soil layer, and the underlying bedrock is tuffaceous siltstone of Middle Jurassic Tangxia formation (an earlier example in China).2) The minimum clear distance of overlapped section of civil engineering section 2227 of East extension line of Shenzhen Metro Line 2 is 1.36M.The overlapped tunnel is basically located in the fully, strongly and moderately weathered tuffaceous siltstone stratum, where the upper part is soft and the lower part is hard
The first time the domestic steel pipe has passed the acceptance of continuous right turn steel tube!The control difficulties of the project are: 1. Continuity: 14.4 meters in total of 12 continuous rings, all of which are Q420C steel pipe pieces; 2. The production is difficult: it is not easy to weld and assemble; 3. The turning radius is very small, and the hole position of all steel pipe pieces is completed with zero error; 4. The project delivery time is tight: less than 60 days from signing the contract to delivery and installation!
