METHOD FOR APPLYING OPTIMAL BRN FOR HIGH-QUALITY DCM CONSTRUCTION

摘要

The present invention relates to a method for applying, to a deep-mixing-processing method, an optimal blade rotation number (BRN) of a rod used in a deep-mixing-processing apparatus so as to increase construction quality. More specifically, disclosed is a technical field relating to a method for applying an optimal BRN for high-quality DCM construction, which rotates a multi-axis rod penetrated into the ground and drawn therefrom and calculates the BRN of the rod by using the number of mixing blades provided on the rod, the speed at which the rod is penetrated or drawn, and the rotational speed at which the rod is penetrated or drawn to determine the number of mixing blades, the rotational speed during the penetration or drawing, and the penetrating or drawing speed so that the BRN can be applied at a management level or higher, thereby maximizing the construction quality of an underground structure to be constructed.;COPYRIGHT KIPO 2020
