The invention discloses a box culvert relay pushing system and a using method thereof. The box culvert relay pushing system is used for pushing box culverts into a tunnel and includes a working platform adjacent to an entrance of the tunnel and the at least two sections of box culverts located on the working platform. The box culvert relay pushing system further includes at least one pushing device used for pushing the box culverts located at front of the entrance of the tunnel, a pulling force device used for pulling the box culverts at the second to n-th section in the first direction and apushing force device used for pushing the box culverts partially or entirely entering the entrance of the tunnel. The pushing devices are arranged on the working platform and are in abutting held withor connected with one box culvert. The pulling force device is connected at the position between the two adjacent box culverts. The pushing force device is arranged between the two adjacent box culverts. The box culvert relay pushing system can be applied to tunnel crossing in a narrow construction site, realizes miniaturization setting of mechanical equipment, reduces technical requirements of the equipment, and improves stability of the equipment.
Description
technical field [0001] The invention relates to the technical field of box culvert pushing tunnel propulsion, in particular to a box culvert relay pushing system and a use method thereof. Background technique [0002] Under the complex environmental conditions of the city, it is often not possible to simply choose the construction method according to the conventional geological and hydrological conditions, but to consider more factors such as the overall urban planning, the impact of existing facilities, and environmental safety requirements. [0003] Among the existing tunnel crossing technologies, the construction technologies that can adapt to urban conditions mainly include shield tunnel construction, underground excavation tunnel construction, and box culvert jacking construction. [0004] First, the shield method: [0005] Mainly applicable environmental sites: clay and fine sand, using earth pressure balance shield; sand, gravel and pebble formation, using mud-water ...
