The driving of rock tunnel, even ground work in the engineering construction such as mine rock tunnelling and water conservancy, railway, highway, national defence
The brill of the rock developing of journey splits helldriver.
Background technology
The piercing technique method of rock tunnel has two kinds in the world at present, first, drilling and blasting method, technological process are：Bore blast hole
→ explosive blasting → ventilation depositing dust → is slagged tap；Second, shield method, technological process are：Engineering preparation (vertical shaft or inclined shaft, for transferring
TBM shield machine systems) → shield machine system installation → continuous driving → continuously slags tap.
Drilling and blasting method technique tradition, belongs to discontinuous process, and each procedure is both needed to the long period, particularly divulges information depositing dust and to go out
Most times that the consumption of slag process is entirely tunneled, operating efficiency is low, 40m2The daily drilling depth of rock tunnel of left and right section
Less than 10 meters, security is low, big to workmen and equipment menace.In addition, drill bursting construction is of poor quality, country rock is shaken by explosion
Dynamic to cause to loosen and unstable, supporting requires high, bores quick-fried technique in Urban Underground or the environment for being not allow for this vibrations damage and is
Do not allow what is used, it is often more important that it is seriously controlled that the explosive needed for explosion is in security purpose.Therefore, quick-fried technique is bored in tunnel
More fall behind in excavation work.
Shield method technique is advanced, and equipment is high-end, and good engineering quality, efficiency is higher, this be also use at present it is more and more
Rock tunnel piercing technique and equipment.But shield method engineering preparation workload is big, investment is high, equipment set-up time length, dress
Machine capacity is big, and electric energy and cutter consumption are big, and overall operation cost is high, and maximum limitation is the adaptability of formation hardness, rock
Stone hardness is less than 90MP/cm2When do not apply to, and the bigger driving speed of hardness is slower, and cutter loss is more serious, and cost is higher, surpasses
Cross 180MP/cm2Shi Jiben can not work.
