Control method of deep cement mixing method

摘要

The present invention relates to an excavation control method of the deep mixing process method, and relates to an excavation control method of the deep mixing process method that can detect whether the excavation equipment has reached the rock layer that is the support layer. To this end, under the control of the control unit, the auger is moved to the excavation position, drilled at a predetermined excavation speed, and when the target underlayer is reached, cement slurry is injected and ascending and descending by a predetermined height based on the target underlayer is repeated. The control unit is configured to inject the cement slurry while the auger is pulled up at a predetermined speed to the target upper layer based on the target lower layer, and the auger is preset depth based on the target upper layer. And controlling the control unit to perform the washing operation while drawing up and down after stirring and stirring, wherein the control unit checks whether the excavation of the auger reaches the target lower layer in the step of improving the body. Disclosure control method of the method is disclosed.
