permafrost drilling machine

Abstract

The invention discloses a frozen soil drilling machine. The frozen soil drilling machine comprises a vehicle, a cab and a track, wherein a high-pressure steam furnace is arranged on the upper side ofthe vehicle, the vehicle is connected with a lifting sliding plate through a fixing rod, a slide rail is arranged on one side of the lifting sliding plate, a lifting table is arranged on the slide rail and connected with a drilling rig through a hinged seat, a drill pipe is arranged on the drilling rig, a steam nozzle is formed in the drill pipe, and the high-pressure steam furnace is connected with the drilling rig through a steam pipe. The frozen soil drilling machine can melt frozen, melting the periphery of frozen soil by heating during drilling and excavation, drilling and excavation of frozen soil are facilitated, and steam can provide power and can be secondarily used for melting the frozen soil by heating.

Description

technical field [0001] The invention discloses a frozen soil excavating machine, in particular to a frozen soil drilling machine. [0002] technical background [0003] The permafrost stratum is a common complex stratum in the process of geotechnical engineering construction. The characteristics of frost heaving and thawing of the permafrost can easily damage the surface buildings. To solve this problem, the current effective and reliable solution is to use the permafrost Carry out excavation, and then backfill the normal soil, so as to fundamentally solve the permafrost hazard; however, due to the complexity of the permafrost coverage and buried depth, the excavation and backfill will not be complete, and a small-scale frozen-thaw cycle will remain , which has laid hidden dangers for the long-term safety of surface buildings. [0004] However, the permafrost has been frozen for many years and the texture of the permafrost is hard. It is difficult to quickly excavate the per...

[0003] The permafrost stratum is a common complex stratum in the process of geotechnical engineering construction. The characteristics of frost heaving and thawing of the permafrost can easily damage the surface buildings.

[0004] However, the permafrost has been frozen for many years and the texture of the permafrost is hard. It is difficult to quickly excavate the permafrost during drilling and excavation. Moreover, the traditional drilling of permafrost excavation uses blasting and manual excavation, and the excavation speed is slow. Moreover, it is prone to danger when excavating frozen soil and drilling. The use of machinery is also to use high-horsepower machinery for excavation, and the excavation speed is slow. When the thickness of the frozen soil passes, the excavator is also very difficult to perform excavation
