Embodiment 1
[0047] The present invention relates to a horseshoe-shaped open shield body structure and its shield method construction technology. The horseshoe-shaped open shield body structure first meets the requirements of the design section, adopts a horseshoe-shaped section, and utilizes 12 hydraulic jacks 5 in the periphery and a combination of shaped steel A detachable and removable reaction force system is combined with the first-stage support and shield safety guarantee to complete the excavation work. After one section is excavated, the reaction force system is removed, and the concrete layer 2 is lined to complete the construction of the cave body structure.
[0048] The cross grid horseshoe shield was initially selected, and several jacks installed around the tail of the shield worked together to cut the soil with the front grid, and backhoe the back of the grid to load the truck to realize the excavation of the soil. The backhoe is installed in the shield body. During the jack...
