Abstract

The invention discloses a horizontal jet grouting drilling machine which comprises a chassis, a drilling machine platform arranged on the chassis, a front lifting arm and a rear lifting arm respectively arranged at the front end and rear end of the drilling machine platform and a cantilever crane jointly supported by the front lifting arm and the rear lifting arm, wherein a head rig which is used for driving a drilling rod to operate and an anchor machine which is used for driving an anchor rod to operate are arranged on the cantilever crane. According to the horizontal jet grouting drilling machine provided by the invention, a drilling rod component is arranged on the head rig of the cantilever crane, and then an external high-pressure slime pump is used for drilling and jet-grouting into a pile, the anchor machine can be used for striking the anchor rod and a pipe shed and reinforcing a jet-grouting pile or a support surface, a multifunctional machine can be realized, the construction equipment can be reduced and the grouting reinforcing efficiency can be increased.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering machinery, in particular to a horizontal jet jet drilling machine. Background technique [0002] In the current tunnel engineering construction, there are various construction machinery products suitable for various construction methods, among which the horizontal rotary jet drilling machine is the most commonly used one. [0003] When working, the horizontal rotary jet drilling rig drills along the outer contour of the tunnel excavation. With the high-pressure pump as the power source, the prepared slurry is sprayed into the soil through the drilling rig drill pipe and nozzle, and the jet stream slowly rotates and advances and retreats in the nozzle. At the same time, the soil is cut with huge energy, and the soil particles are forced to mix with the slurry. After the slurry is solidified, a horizontal cylindrical cement-soil consolidation body is formed, that is, a horizontal jet grou...
