Parameter optimization simulation of high-pressure water jet reaming equipment

In this paper, the study concludes that reaming grouting anchorage is more effective than traditional anchorage, and the study of water jet reaming equipment. This paper mainly does simulation analysis of water jet nozzle parameters by Comsol, and optimizes its parameters by simulating the nozzle length, nozzle diameter and inlet pressure of the nozzle, so as to obtain the relatively optimal combination of water jet nozzle parameters.
