Description

Technical Field

[0001] The utility model belongs to the technical field of drilling machines, in particular to a drilling machine device for MJS process construction. Background Art

[0002] The MJS process (Metro Tet Syetem process) is also known as the all-round high-pressure jetting method. Based on the original high-pressure jet grouting method, it uses a ground pressure monitoring device, a unique multi-channel drilling tool and a forced mud suction device at the front end of the drill bit to achieve forced slurry discharge in the hole and ground pressure monitoring, and controls the ground pressure by adjusting the forced slurry discharge volume, reducing the possibility of surface deformation, reducing the impact of construction on the surrounding environment, and further ensuring the pile diameter. The MJS super jetting method is a new method. It uses triple or quadruple tubes to transport three media, water, gas, and slurry respectively. The cement slurry is sprayed with ultra-high pressure (35-40Mpa) and the air flow around it is used for secondary impact cutting of the soil to form a larger diameter and evenly stirred rotary jet body. The diameter of the MJS ultra-high pressure rotary jet pile is significantly larger than that of the domestic triple tube rotary jet pile, and the impact on the surrounding environment is greatly reduced. The MJS process requires a drilling rig. The existing drilling rig is not convenient to move due to its large size. Utility Model Content
