DETAILED DESCRIPTION OF EMBODIMENTS

[0029] Embodiments of the invention provide a travelling-type tunnel hard-rock micro-damage cutting equipment and a construction method associated therewith. The method may include the following step 1 through step 7.

[0030] Step 1, preliminary preparation operation: rock mass information including integrity and nature of a rock mass is detected before (the travelling-type tunnel hard-rock micro-damage cutting equipment) entering a tunnel for working, the crawler-type trolley 13 then is started and various properties of the hard-rock drilling construction apparatus and the hard-rock cutting construction apparatus are checked.

[0031] Step 2, drilling position determination: appropriate drilling locations and depth are determined according to the preliminary detected rock mass information and secondary processing information of rock, after manipulating the crawler-type trolley 13 to enter a predetermined working area of the tunnel.

[0032] Step 3, drilling operation: firstly the driller 9 is adjusted by an operator according to the drilling depth, the drilling power arm 4 then is controlled through the manipulation cab 17 (drilling manipulation room) to drill holes around a surrounding rock 19 to demarcate a whole rock mass to-be-cut from the surrounding rock 19, and subsequently a drilling is performed on the drilling locations according to use needs of rock.

[0033] Step 4, rock-breaking and cutting position adjustment: the hard-rock drilling construction apparatus is terminated working after the drilling operation is completed; and in the manner of no need of turning, the rock-breaking power arm 18 then is controlled through the manipulation cab 17 (cutting manipulation room) by the operator to make the hard-rock cutting construction apparatus be aligned with a drilled hole 20.

[0034] Step 5, transversal cutting operation: firstly the hard-rock cutting device 12 is deepened into the drilled hole 20 by the operator, and during the deepening, an illumination switch on the visual operation terminal 2 is turned on and positions of transversal hydraulic steel rods 11 are observed via a display on the visual operation terminal to ensure the transversal hydraulic steel rods accurately reach a working position, then the transversal hydraulic steel rods 11 are activated through the visual operation terminal 2 to perform a hard-rock cutting, and an infrared switch on the visual operation terminal is turned on for auxiliary observation when observation effect for the hard-rock cutting is poor (i.e., not good).

[0035] Step 6, longitudinal cutting operation: a longitudinal cutting operation is performed according to a project need after the transversal cutting operation is completed, and specifically the transversal hydraulic steel rods 11 are closed through the visual operation terminal 2 and longitudinal hydraulic steel rods 11 are opened through the signal sensor 16, to continue performing the working of cutting.

[0036] Step 7, transportation operation: the detachable drilling device 7 is replaced with a five-claw hook 14 after the (transversal and longitudinal) cutting operations are completed, the crawler-type trolley 13 equipped with the self-unloading tipping bucket 1 is turned in situ, cut rocks is hoisted/lifted to the self-unloading tipping bucket 1 by the five-claw hook 14 and then transported out of the tunnel with the crawler-type trolley 13, and a lining construction is carried out in time on the cut rock mass.
