Description

Technical Field

[0001] The utility model relates to the technical field of pipe gallery well opening, in particular to a hole opening device for a top-type outlet well of a top-tube type comprehensive pipe gallery. Background Art

[0002] Due to favorable surrounding site conditions, open-cut integrated pipe corridors generally have integrally cast pipeline branch openings or outlet wells, and the location of outlet lines is free. If the trenchless integrated pipe corridor adopts the rectangular jacking construction technology, the outlet lines are generally concentrated at the jacking working well.

[0003] Although the open-cut construction method is mature and has low risks, it requires large-scale excavation of foundation pits, so it is usually not suitable for sites with heavy traffic, dense population, many ground buildings, and complex underground pipelines. As a trenchless engineering technology, rectangular jacking has effectively solved the problems of damage to urban buildings and road traffic congestion during pipeline burial construction. However, due to the deep burial depth of the pipeline corridor, the outlet locations of different pipelines are concentrated in the jacking working well. The spacing between the jacking working wells is usually large, resulting in the connection position between the outlet of the pipeline inside the corridor and the pipeline outside the corridor is often not the most appropriate and economical.
