Technical Details & Applications
Construction configuration
Dashou provides equipment configuration, construction planning, and field execution for large-section and mega-section rectangular pipe jacking. Machine selection and construction arrangements are tailored to the required cross-section, drive length, ground conditions, soil cover, surrounding infrastructure, and site constraints.
Luxiang Road–Qilianshan Road Link, Shanghai
The project used a 9.9 m × 8.15 m rectangular jacking section for two drives, each 445 m long, with a separation of 10 m. The alignment passed beneath Gucun Park and the S20 Outer Ring Expressway. Soil cover beneath the expressway was approximately 3.3 to 3.95 m, compared with approximately 3.65 to 5.5 m elsewhere along the alignment. The project combined long-distance jacking, a large cross-section, and shallow-cover construction beneath an expressway.

Provincial Hospital–Dongmen Section, Fuzhou Metro Line 4
This metro interchange section used a 10.8 m × 7.5 m rectangular jacking section over a single drive of 190.423 m. The alignment passed through soft muddy strata with approximately 10 m of soil cover and ran longitudinally beneath Dongda Road, a major urban road. The project involved large-section metro tunnel construction alongside existing buildings and urban infrastructure.
福州地铁4号线省立医院站—东门站区间
该地铁换乘段采用10.8 m × 7.5 m矩形顶管断面，单次顶进长度190.423 m。顶管穿越淤泥层，覆土厚度约10 m，并沿东大路交通主干道纵向下穿。项目涉及大断面地铁隧道施工，以及沿线既有建筑和城市基础设施条件下的工程实施。
