Abstract

The invention discloses a box culvert relaying pushing system with a pushing frame assembly. The box culvert relaying pushing system is used for pushing a box culvert into a tunnel and comprises a work platform adjacent to an inlet of the tunnel, and at least two sections of box culvert bodies located on the work platform; the box culvert relaying pushing system further comprises at least one pushing device used for pushing the box culvert bodies located in front of the inlet of the tunnel, tension devices used for pulling the box culvert bodies from the second section to the n section inthe first direction, and pushing force devices used for pushing the box culvert bodies entering the inlet of the tunnel partially or totally; each tension device is connected between the correspondingtwo adjacent box culvert bodies; each pushing force device is arranged between the corresponding two adjacent box culvert bodies; each box culvert body is provided with a pushing block structure; andeach pushing device is arranged on the work platform and connected with the pushing block structure of the corresponding box culvert body. The box culvert relaying pushing system can be suitable fortunnel passing in a narrow construction site, and miniaturization of mechanical equipment is achieved.

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 a pushing frame 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...
