Large-pipe-diameter mud-water balanced pipe jacking construction method suitable for high-water-level rock geology

The invention discloses a large-pipe-diameter mud-water balanced pipe jacking construction method suitable for high-water-level rock geology. The technical problem that an existing mud-water balanced type pipe jacking construction method cannot meet the requirement for efficient construction in the high-water-level rock geology is solved. The large-pipe-diameter mud-water balanced pipe jacking construction method comprises the steps of equipment installation, jacking starting, thixotropic slurry construction, pipeline jacking, jacking to a receiving well, slag removing and slurry outward transporting, cement and coal ash slurry filling and equipment dismounting. In the whole construction process, thixotropic slurry, deviation rectifying and the like are controlled in real time, and the construction quality and the construction efficiency are guaranteed. According to the large-pipe-diameter mud-water balanced pipe jacking construction method, pipeline excavation of the high-water-level rock geology is achieved
