Description
Technical field
The present invention relates to shield driving technical field, driving engineering method of especially a kind of shield machine in full ground consisting of hard rock.
Background technique
The driving of shield machine mainly squeezes rock by the hobboing cutter on cutterhead, grinds the movement such as quick-fried, to carry out
Broken rock driving, but when running into excessive rock strength or tunneling boring hard rock, especially high-intensitive granite driving, shield machine knife
The hobboing cutter of disk just can not effectively realize the movement quick-fried to the extruding of hard rock or high-intensitive granite and stone roller, the rock breaking capacity of hobboing cutter
Just sharply decline, and the wear rate of hobboing cutter is high；The main reason for such case occur is since shield machine pick formation rock is hard
It spends too big, and tunnels that face is in a kind of gentle breeze or when without weathered state, digging face is the entirety of a rigidity,
Hobboing cutter on cutterhead is to carry out a kind of grinding work with driving face, therefore shield machine drivage efficiency is low in this case
Under, it is extremely difficult to effective rock breaking efficiency, is not a kind of ideal driving state.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of driving engineering method of shield machine in full ground consisting of hard rock, solve
Layer formation hardness is too big, and driving face is in a kind of gentle breeze or without weathered state stratum, digging efficiency is too low to be asked
Topic.
The technical solution adopted by the present invention to solve the technical problems is: a kind of driving of shield machine in full ground consisting of hard rock
Engineering method, have tunneling process, also have cutter head of shield machine it is static, stop driving state under face is successively carried out blasthole drilling,
Filling explosive and ignition charge burst the process of face global tissue, shield machine pair when which is conducive to tunnel again in borehole
Face carries out broken rock digging.
Further, blasthole drilling of the present invention, the process for loading explosive in borehole enter earth material storehouse by operating personnel
Afterwards by the through-hole operation on cutterhead in face.
Or, loading the process of explosive in blasthole drilling of the present invention, borehole by the automatic jig that is installed on native storehouse plate
By the through-hole operation on cutterhead in face.
Further say after filling explosive process also there is filling sealing agent to block borehole in borehole of the present invention
Process.
Further say that also there is the process of dust in cleaning borehole after blasthole drilling process of the present invention.
It further says, shield machine of the present invention, which stops shield machine while driving bursts face process, also to carry out
Spell the work of pipe.
The invention has the advantages that solving defect present in background technique, the construction is on above-mentioned stratum
In, the drivage efficiency of shield machine can be greatly improved, while reducing the hob abrasion of shield machine, reduce integral construction cost,
For shield machine in hard rock and superhard rock driving, remarkable in economical benefits.
Detailed description of the invention
Fig. 1 is concrete technology route schematic diagram of the invention.
Specific embodiment
Presently in connection with attached drawing and preferred embodiment, the present invention is described in further detail.These attached drawings are simplified
Schematic diagram, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
A kind of driving engineering method of shield machine as shown in Figure 1 in full ground consisting of hard rock is that a kind of orientation presplit blasting adds shield
The construction technology technology of structure digging, have tunneling process, also have cutter head of shield machine it is static, stop driving state under to face
It successively carries out blasthole drilling, load explosive in borehole and ignition charge bursts the process of face global tissue, which is conducive to again
Shield machine carries out broken rock digging to face when secondary driving.
Embodiment 1
Cutter head of shield machine is static, stops driving state, is cleaned out by screw machine or the work of muddy water dreg removing system in Tu Cang
The construction space for orienting presplit blasting, is entered after Tu Cang by operating personnel and does through-hole in the way of manually drilling cutterhead
In face, borehole accomplishes fluently rear, dust, disintegrating slag in removing drilling etc. for (blasthole drilling) operation, send explosive then to filling out in borehole
With filling sealing agent, sealing of hole, ignition is finally executed again, after face being impacted certain crack, shield machine is again started up, extensive
It promotes broken rock again, after certain distance, then shuts down, successively reciprocation cycle.
Embodiment 2
Cutter head of shield machine is static, stops driving state, while shield machine is shutting down segment assembly, by screw machine or muddy water
Dreg removing system work cleans out the construction space of orientation presplit blasting in Tu Cang, by the automatic jig being installed on native storehouse plate
(such as impact gun) by the through-hole operation on cutterhead in face, borehole accomplishes fluently rear, dust, disintegrating slag in removing drilling etc., then
It is filled out into borehole and send explosive and filling sealing agent, sealing of hole, finally execute ignition again, after face being impacted certain crack,
Shield machine is waited to complete pipe sheet assembling link, shield machine is again started up, recovery propulsion broken rock, after certain distance, then is shut down, successively
Reciprocation cycle.
The quantity of borehole can according to the actual situation depending on, explosive can be common gunpowder and be also possible to chemically expansible explosive,
Depending on the power of the explosion of explosive is by actual conditions.
This engineering method is that orientation Pre-splitting Blasting Technique is increased during shield driving, using orientation presplit blasting,
Shield machine needs the face of digging to impact crack etc., and face global tissue is made to form fracture, fracture state, in favor of shield
The broken rock of structure machine hobboing cutter.Also, this engineering method does not need to survey in advance or disposable large area, long range explosion, this engineering method can be
According to actual conditions when being tunneled in tunnel during driving, just implement as needed, it can be achieved that driving-presplit blasting friendship
For process.
It is a specific embodiment of the invention described in above instructions, various illustrations are not to reality of the invention
The limitation of matter Composition of contents, person of an ordinary skill in the technical field can be to described in the past specific after having read specification
Embodiment is made an amendment or is deformed, without departing from the spirit and scope of invention.
