Vacuum grouting technology of fragmented rock foundation
The invention discloses a vacuum grouting technology of a fragmented rock foundation. The vacuum grouting technology of the fragmented rock foundation comprises the three steps of drilling, drilling gap washing and pump-in testing, vacuumizing and high-pressure grouting. The vacuum grouting technology of the fragmented rock foundation overcomes the defects in the prior art. The vacuum grouting technology for the fragmented rock foundation is provided. In the foundation rock processing process, it can be guaranteed that grout can be fast and evenly diffused into foundation rock under the joint action of grouting pressure and a rock foundation fracture, and not only can grouting efficiency be improved, but also the quality of the rock foundation is improved after grouting.
