Description

Cities and towns Shi Zhi tunnels cantilever tunneling construction engineering method
Technical field
The invention belongs to tunnel excavation technical field of construction, and in particular to a kind of cities and towns Shi Zhi tunnels cantilever tunneling construction Engineering method.
Background technology
Rock stratum section tunnel traditional at present typically uses blast working.Blast working construction risk itself is larger, to week Casing soil disturbance is larger, easily causes surrounding soil to cave in.Face rock stratum is backbreak more serious, the cubic metre of earth and stone during blast working Outward transport increases with first branch spray shield amount, causes the waste of people, material, machinery, and the lengthening of spray shield time, sealing cycle lengthen danger in addition Dangerous increasing.Particularly job location is located at city proper, and surface line is complicated, and both sides house is nearer, and blast working is dangerous It is bigger.
The content of the invention
The present invention is solution the deficiencies in the prior art, there is provided a kind of cities and towns Shi Zhi tunnels cantilever tunneling construction engineering method.
The present invention is achieved by the following technical solutions：A kind of cities and towns Shi Zhi tunnels cantilever tunneling construction engineering method, including Following steps：
（1）Surveying setting-out：Contour line is released, laser is positioned；
（2）Face punching splitting：Splitting is coordinated using splitting machine and rock drill is constructed, using auxiliary bore hole splitting as auxiliary Mode, rock texture is destroyed, tunneled after discharging rock stress；Boring aperture is 5.5cm, and cloth pitch of holes is 0.5m, into plum blossom-shaped Arrangement；
（3）Top bar tunneling construction：Driving contour line is determined using laser orientation instru-ment, top bar is highly 5.6m；Tunneling process Middle boom-type roadheader cutterhead external spraying system sprays water smoke and carries out depositing dust, and air exhauster system opens in boom-type roadheader construction It is dynamic, flue dust is discharged backward；
（4）Steel arch-shelf reinforced mesh is constructed：After tunnel top bar driving, scarfing cinder, unwrapping wire, steel arch-shelf and bar-mat reinforcement are installed Piece；
（5）Advanced conduit construction：Headed into using air drill jewel hole, and by steel pipe in hole, steel pipe tail end welds with steelframe or system anchor bolt It is connected together, adds circumferential reinforcement if necessary；Slip casting determines to terminate the time according to pressure condition and running pulp situation；
（6）Gunite concrete：Using wet shot machine operation, spraying operation from arch springing or foundation from bottom to top, segmentation, burst, layering Spray to design thickness；
（7）Get out of a predicament or an embarrassing situation tunneling construction：Height of getting out of a predicament or an embarrassing situation is 2.4m, and first branch inverted arch is highly 0.85m；Tunnel get out of a predicament or an embarrassing situation driving when, Boom-type roadheader first digs centre, and main hole bow member both sides respectively retain 1m；Both sides are staggeredly tunneled when driving is got out of a predicament or an embarrassing situation, a side seal Close and carry out opposite side construction after cyclization again；Pin framves edge is abolished using oil hammer during first branch inverted arch driving makes up a deficiency；Hanged in tunneling process Road headers cutterhead external spraying system sprays water smoke and carries out depositing dust, and air exhauster system starts in boom-type roadheader construction, Flue dust is discharged backward.
Preferably：
In step（7）In, after the completion of tunneling construction of getting out of a predicament or an embarrassing situation, first branch inverted arch abolishes remaining rock stratum using oil hammer.
Beneficial effects of the present invention are：
First, boom-type roadheader construction not only avoid the greater impact of explosion, and the damage to country rock is small, is nearly free from pine Relax, chip off-falling, avalanche it is dangerous minimum, also substantially increase working face security, reduce and vibrate influence to surrounding building；
2nd, tunnel cross-section forming accuracy is high, can control out break by drill bit driving, especially be abolished with oil hammer, cleaves and abolish Compared etc. cold digging method weak surrounding rock, efficiency of construction is high；
3rd, cantilever excavator continuously excavate, without concussion of blasting, can more freely determine opportune moment of surrounding rock supporting, reduce super Dig, the expense of rock support and lining cutting can be saved.
Embodiment
Specific embodiment of the invention given below is, it is necessary to which explanation is that the invention is not limited in implement in detail below Example, all equivalents done on the basis of technical scheme each fall within protection scope of the present invention.
A kind of cities and towns Shi Zhi tunnels cantilever tunneling construction engineering method, comprises the following steps：
（1）Surveying setting-out
Contour line is released, laser is positioned；
（2）Face punching splitting
Splitting is coordinated using splitting machine and rock drill is constructed, and using auxiliary bore hole splitting as supplementary mode, destroys rock texture, Tunneled after release rock stress；Boring aperture is 5.5cm, and cloth pitch of holes is 0.5m, is arranged into plum blossom-shaped；
（3）Top bar tunneling construction
Driving contour line is determined using laser orientation instru-ment, top bar is highly 5.6m；Boom-type roadheader cut in tunneling process Head external spraying system sprays water smoke and carries out depositing dust, and air exhauster system starts in boom-type roadheader construction, and flue dust is discharged backward；
（4）Steel arch-shelf reinforced mesh is constructed
After tunnel top bar driving, scarfing cinder, unwrapping wire, steel arch-shelf and reinforced mesh are installed；
（5）Advanced conduit construction
Headed into using air drill jewel hole, and by steel pipe in hole, steel pipe tail end welds together with steelframe or system anchor bolt, adds if necessary Circumferential reinforcement；Slip casting determines to terminate the time according to pressure condition and running pulp situation；
（6）Gunite concrete
Using wet shot machine operation, spraying operation from arch springing or foundation from bottom to top, segmentation, burst, layering injection to design thickness；
（7）Get out of a predicament or an embarrassing situation tunneling construction
Height of getting out of a predicament or an embarrassing situation is 2.4m, and first branch inverted arch is highly 0.85m；Tunnel get out of a predicament or an embarrassing situation driving when, during boom-type roadheader is first dug Between, main hole bow member both sides respectively retain 1m；Both sides are staggeredly tunneled when driving is got out of a predicament or an embarrassing situation, and are carried out again after one side closed cyclization another Construct side；Pin framves edge is abolished using oil hammer during first branch inverted arch driving makes up a deficiency；In tunneling process outside boom-type roadheader cutterhead Spraying system sprays water smoke and carries out depositing dust, and air exhauster system starts in boom-type roadheader construction, and flue dust is discharged backward.Leave office After the completion of rank tunneling construction, first branch inverted arch abolishes remaining rock stratum using oil hammer.
