The invention discloses a box culvert relaying pushing system with anchor rope components. The box culvert relaying pushing system is used for pushing box culverts into a tunnel and comprises a working platform, at least two box culverts, at least one pushing device, at least one pulling device and at least one thrust device, the working platform approaches to an entrance of the tunnel, the box culverts are positioned on the working platform, the pushing devices are used for pushing the box culverts positioned in front of the entrance of the tunnel, the pulling devices are used for pulling thebox culverts from the second section to the n section along a first direction, the thrust devices are used for pushing the box culverts partially or completely entering the entrance of the tunnelalong the first direction, the pushing devices are arranged on the working platform and abutted against or connected with one box culvert, each pulling device is connected between two adjacent box culverts, and each thrust device is connected between two adjacent box culverts. The box culvert relaying pushing system is applicable to tunnel traversing of narrow construction sites, so that mechanical devices are small, the technical requirements of the devices are reduced, and stability of the devices is improved.
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 with an anchor cable assembly. Background technique [0002] Under the complex environmental conditions of the city, it is often not possible to simply choose the construction method based on the geological and hydrological conditions, but also consider various 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 balance...
