Description
Technical field
The present invention relates to a kind of basement rock crushing devices of tunnelling protrusions, belong to machinery field.
Background technique
During tunnel excavation, boulder and basement rock protrusion problem are often met, the boulder and prominent when using shield driving
The basement rock risen is very serious to the damage of the drill bit of shield machine, cutterhead and cutter, seriously affects construction speed, engineering is significantly increased
Cost.Therefore, rationally processing tunnel excavation during the boulder met and protrusion basement rock, going on smoothly and saving to engineering
Engineering cost is of great significance.
The method of processing boulder and the basement rock of protrusion mainly has at present: first is that boulder and protrusion in shield tunneling process
Basement rock handled, such as directly cut the basement rock of boulder and protrusion using shield, in hole the basement rock of explosion boulder and protrusion or
The basement rock of the processing of hydraulic splitting machine boulder and protrusion in hole；Second is that being located in advance before shield-tunneling construction to the basement rock of boulder and protrusion
Reason, such as being excavated the basement rock of boulder and protrusion using artificial digging pile, rock surface drills and then broken machine using hydraulic rock will
Basement rock struts, the basement rock of surface drilling explosion boulder and protrusion, using basement rock of broken stone swelling agent spalling protrusion etc..
Above-mentioned several ways are attained by brokenly the effect of stone, but in tunnelling, can not predict basement rock and be imbedded in ground
Depth in face, thus basement rock is entirely dug get up it is unrealistic；Hydraulic rock breaks machine, and to break effect preferable, but for tunnel
The basement rock at top, hydraulic rock break machine and are difficult to fix；The mode that stone is broken in explosion has certain risk in tunnel, falls
Rock may injure worker, and the huge impact force meeting tunnel top strata structure of explosion by a crashing object, there is collapsing risk；Swelling agent peace
It is complete reliable, but the broken rock time is longer, will affect the tunnel excavation duration.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is providing in a kind of tunnelling
