Integral strength has joints cement in the steel floral tube of hole so that having hole steel floral tube more closely to be fixed with rock stratum, while concrete pair
Crack between rock stratum is filled, and strengthens the connection between rock stratum so that rock stratum is not easy to loosen, and enhances the whole knot in tunnel
Structure intensity.
The present invention is further arranged to：Concrete ejection technique in the step E is：It is carried out by concrete sprayer
The injection of concrete, concrete are filled arch inside, will when Concrete Filled is to more than a half space inside arch
Splash guard is fixedly attached on arch and carries out the welding between splash guard, then by concrete injection splash guard and arch it
Between, splash guard is made to be bonded with concrete, carries out the injection of second coagulation soil later.
By using above-mentioned technical proposal, the filling of concrete causes arch to be more firmly fixed on tunnel inner wall,
The intensity in tunnel is enhanced, splash guard is fixedly connected on arch and is bonded with concrete, and splash guard is improving tunnel water proofing
The intensity of arch is enhanced while energy, the injection of second coagulation soil causes splash guard is more firm to be fixed in tunnel, makes to prevent
Water plate is not easy to generate gap between arch, further enhances tunnel water proofing ability.
The present invention is further arranged to：Concrete in the step E is formulated by following raw material：Aggregate, cement, water
And flyash.
By using above-mentioned technical proposal, the addition of aggregate causes cement to be relatively easy to be molded, and flyash has itself
Stronger water imbibition so that the water imbibition for the concrete made is stronger, so as to reduce the probability of water seepage of tunnel.
The present invention is further arranged to：Lining construction technique in the step G is：Concrete is injected into lining trolley
Mold in, vibrating for concrete is carried out by the hunting system of lining trolley, and pass through plug-in type and make stick firm by ramming and carry out part area
Domain is vibrated, plug-in type make firm by ramming stick using when to insert and pull out slowly soon.
By using above-mentioned technical proposal, the hunting system of lining trolley vibrates to the entirety of concrete, plug-in type
It makes stick firm by ramming to vibrate to the reinforcement of certain key areas, plug-in type makes stick quick insertion firm by ramming, can improve the area that vibrates；Vibrating spear is slow
Extract, avoid plug-in type make firm by ramming stick mix in withdrawal process air formation bubble；Concrete layer can be effectively removed by vibrating
In bubble, so as to improve the firmness of concrete layer.
The present invention is further arranged to：Concreting technique in the step F is：Concrete is from center to both sides pair
Claim cast, inverted arch is made firm by ramming closely knit with tunnel side wall joining place.
By using above-mentioned technical proposal, center is symmetrically poured to both sides so that concrete is more uniformly distributed
On the surface in tunnel, inverted arch is fiddled with closely knit with tunnel side wall joining place so that the bottom end of inverted arch is more firm, improves tunnel
Integral strength.
In conclusion the invention has the advantages that：
1st, by being fixedly connected with splash guard on arch, splash guard can be fixed on arch in concrete ot-yet-hardened, work
People can carry out waterproof construction faster, shorten the construction time；
2nd, by setting reinforced frame and stabilizing bracket.So that be oriented to wall carry out hole steel floral tube and non-porous steel floral tube when piercing compared with
It is firm, reduces and be oriented to wall lodging probability；
3rd, by adding in flyash in the configuration process of concrete so that the water absorbing capacity of concrete greatly enhances, and reduces
The infiltration probability in tunnel.

Fig. 1 is the process flow diagram of the present invention.
Specific embodiment
With reference to attached drawing, the present invention will be further described.
A kind of constructing tunnel technique, includes the following steps：
A, photoface exploision：It first carries out boring the more uniform drilling of several distributions on massif, be carried out later by hydraulic giant device to hole
Cleaning, makes not remain aggregate chips in hole, then explosive is put into the hole being drilled, and explosive is made to be located at bottom hole, is passed through later
Stemming device to hole is closed, and is then connected blasting circuit and is carried out bursting work, the clear of rubble is carried out after the completion of bursting work
Reason, handles unexploded explosive, and explosive uses emulsion.
B, super-front large pipe shed is constructed：Scar is rinsed by hydraulic giant, the dust and rubble of scar are cleared up, it will
Concreting into guiding wall be fitted at tunnel portal, later by domed reinforced frame be fixed on be oriented to wall on, reinforcing bar
The upper stabilizing bracket of both ends welding of frame, the bottom of stabilizing bracket are inserted into soil, pass through track of the hydraulic drill rig along guiding wall later
It drills, drilling is uniformly distributed along the path length for being oriented to wall, has been put into hole steel floral tube and the non-porous spray of molten steel in drilling later
Pipe, has hole steel floral tube and non-porous steel floral tube to be spaced apart, and injects cement mortar having in the steel floral tube of hole later.
C, advanced tubule is constructed：After tunnel excavation, the surface in tunnel is rinsed by hydraulic giant, makes the table in tunnel
Face is more clean, is tilted along the excavation direction in tunnel and squeezes into ductule, injected hole is offered in the middle part of ductule, when ductule arrives
Rock disintegrating slag is blown out by blowpipe behind position, carries out slip casting in ductule later, slurries are cement mortar, the ratio of mud 0.5:
1。

Tunnel side is vertical, and grouting rock bolt or hollow grouting anchor are inserted into hole, early strength cement slurry is injected into grouting rock bolt later
In, cement mortar is injected into hollow grouting anchor, then installing backing plate, nut is tightened.
E, waterproofing reinforcement is constructed：First the arch in frame-like being made of reinforcing bar is mounted on tunnel inner wall, makes arch
Upper surface be more closely bonded with tunnel inner wall, then the inner wall in arch and tunnel is rinsed well by hydraulic giant, later
By concrete sprayer into being about on concrete ejection to tunnel inner wall, concrete is made to accumulate gradually, gradually in arch
Portion is filled, and when Concrete Filled is extremely more than the half of arch inner space, stops the injection of concrete, at this time by waterproof
Plate is welded on arch, and then concrete is injected into the space between splash guard and arch by pipeline, leans on splash guard
The side of nearly arch is bonded with concrete, is vibrated later by plug-in type vibrating stick to concrete, internal vibration stick exists
Fast insert is needed to pull out slowly during operation, internal vibration stick cannot contact arch and splash guard, then between adjacent splash guard into
Row welding, continues the injection of concrete, then carries out watering health to concrete later.
F, inverted arch is constructed：First by inverted arch reinforcement installation in tunnel, make the upper surface of inverted arch reinforcing bar and the surface of concrete
Fitting, later to inverted arch casting concrete, concrete is poured from center to both sides, later by plug-in type vibrating stick to facing upward
The concrete of arch reinforcing bar bottom end make firm by ramming closely knit.
G, lining construction：Lining trolley enters tunnel internal, punching block be located at lining trolley template and concrete it is interior
Between wall, by concreting between the template of lining trolley and the inner wall in tunnel, pass through the hunting system pair of lining trolley
Concrete vibrates, and is vibrated in individual sites by plug-in type vibrating stick, and internal vibration stick needs in operation
Fast insert is pulled out slowly, and internal vibration stick cannot contact reinforcing bar and template, the progress stripping operation and by lining cutting platform after concrete setting
Vehicle removes tunnel internal.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
