Novel vertical shaft heading machine and construction method thereof

Abstract

The invention relates to the technical field of vertical shaft constructing, in particular to a novel vertical shaft heading machine. The novel vertical shaft heading machine comprises a stand column, a cutter disc, a main driving unit, a plurality of stabilizers, a first-layer platform, supporting platforms, a second-layer platform, a third-layer platform, a fourth-layer platform, a boot-supporting advancing unit and a slag discharging unit, wherein the stand column is arranged to be coaxial with a vertical shaft, the vertical shaft is arranged at the lower end of the stand column, the main driving unit is installed between the cutter disc and the stand column, the multiple stabilizers are installed around the lower end of the main driving unit, the first-layer platform is installed above the multiple stabilizers, the supporting platforms are upwards fixedly installed around the stand column in sequence, and the slag discharging unit is perpendicularly installed in the middle of the stand column; and the cutter disc is fixedly connected with the output end of the main driving unit. According to the novel vertical shaft heading machine, through mechanical excavation, disturbance of blasting on the stratum is reduced, meanwhile the mechanical excavation can improve the shaft wall construction quality, and the construction quantities of over-excavation and under-excavation are reduced; construction cost is reduced, devices are highly integrated, and after excavating is conducted, supporting closely follows; and the side gap is small, the shaft wall is supported in time, construction safety can be ensured, and simultaneously the slag discharging unit is designed.

Description

technical field [0001] The invention relates to the technical field of shaft construction, in particular to a novel shaft boring machine and a construction method thereof. Background technique [0002] At present, blind well construction technologies mainly include common sinking method and drilling method. The main equipment of the ordinary drilling method includes rock drilling, rock grabbing machine, hanging plate and other equipment. The drilling and blasting method is used to excavate the shaft, which has complicated construction technology, low efficiency, low safety factor of workers and high labor intensity; the drilling method mainly The equipment is shaft drilling rig, which adopts pressurized drilling, and the drilling efficiency is low. For example, some drilling tools have very low excavation efficiency when encountering hard rock and other strata. Larger vertical shafts must be excavated and reamed, and the excavation cannot be completed at one time. After the...

Problems solved by technology

The main equipment of the ordinary drilling method includes rock drilling, rock grabbing machine, hanging plate and other equipment. The drilling and blasting method is used to excavate the shaft, which has complicated construction technology, low efficiency, low safety factor of workers and high labor intensity; the drilling method mainly The equipment is shaft drilling rig, which adopts pressurized drilling, and the drilling efficiency is low. For example, some drilling tools have very low excavation efficiency when encountering hard rock and other strata. Large vertical shafts must be excavated and reamed, and the excavation cannot be completed at one time. After the drill pipe breaks, it is troublesome to repair, which has a great impact on the entire construction

Another example is that before the construction of some vertical shafts, it is necessary to cooperate with freezing drilling and blasting around the formation. The underground working conditions of workers are harsh, the safety factor is low, the efficiency of slag extraction after excavation is low, and the cost of freezing around the formation is high.

The construction of shafts still uses traditional construction equipment and construction methods. With the development of society, the disadvantages of traditional construction methods are becoming more and more obvious, which limits the development of shaft construction technology.
