Description
Technical field
The present invention relates to a kind of construction method of tunnel-liner, and in particular to point of a kind of concrete incline shaft transport and tunnel
Area's casting method.
Background technology
When tunnel cross-section is smaller, the inclined shaft gradient reaches 24 °, the discrepancy in elevation reach 213.5m and more than, inclined shaft length reaches
During 575.75m, the Bian Wa sides lining cutting of inclined shaft tunnel is difficult to, to ensure construction safety and engineering safety after the completion of excavation how
Realize in hole that transport is not disturbed, the way traffic space of the inside lining parallel operations of concrete transportation hole and transport channel is construction
When problem.The country now build similar tunnel, in order to ensure tunnel-liner can typically take without interruption full hole pick completely bottom and
Bottom cushion is poured finish after concentrate and pour, in hole in the mode of the main material such as transport concrete and reinforcing bar selecting sequence operation, hole
Concrete is transported using tank car.This kind of engineering method by process due to being arranged, the narrow limitation of transporting equipment and operating area, during either simplex sequence
Between it is long, need exact sequence operation, last process directly restricts the implementation of subsequent processing, and construction speed is slow, not motor-driven, dumb,
There is larger hidden danger to job safety.Therefore there is no a set of compared with system, peace in tunnel construction sections for middle narrow-bore tunnel in the prior art
Entirely, quick construction method.
The content of the invention
The technical problem to be solved in the present invention is：A kind of long inclined shaft narrow-bore tunnel concrete transportation of heavy grade and lining are provided
Build construction method, with overcome prior art exist activity time length, construction organization is loose, work efficiency is low, cost is high, inter process not
The problems such as energy parallel operations, tunnel concrete transport are discontinuously, construction equipment is dumb motor-driven.
Technical scheme
A kind of long inclined shaft narrow-bore tunnel concrete transportation of heavy grade and lining construction method：Inclined shaft penetrates master from tunnel side
Concrete after hole, mix enters the collecting bin of inclined shaft bottom by the chute installed on inclined shaft, is then transported to by delivery pump
Both sides casting area, each casting area is carried out subregion and poured using four sets of end templates and two sets of side arch templates.
It is as follows that subregion pours order：
First, reinforcing bar row is into after flowing water, and end template and floor bow member that first first, the firstth area of making pours storehouse erect abutment wall arch
Frame, sidewall template, install arch bow member, arch template；
2nd, the end template and floor bow member that making second pours storehouse；
3rd, the first storehouse is poured；
4th, after solidifying, the sidewall template and arch template in a upper storehouse are removed, and is installed to next storehouse；The orlop template of making the 3rd
With bottom plate bow member；
5th, the second storehouse is poured；
6th, repeat step four, five is until poured the firstth area, and the whole moulds of dismounting are transported to next area.
7th, repeat step one to six, completes pouring for the secondth area and subsequent zone.
Inclined shaft bottom sets the collecting bin more than 2.5m3.
When inclined shaft uses a chute, inclined shaft pin sets a concrete pump to switch by delivery pump bend pipe and realized
The switching that upper and lower tunnel concrete is poured；Inclined shaft realizes concrete transportation grade separation when setting two chutes by the setting of elevation
Transport and switching.
The same scope of operation, which is set, when subregion is poured is no more than 200m.
Beneficial effects of the present invention：
Spoil disposal transport is solved by inclined shaft chute and concrete enters the interference that hole pours transport parallel operations, passes through main tunnel
Pumping relay overcomes flexible transport in hole, concrete transportation and picks the narrow and small difficulty of bottom equipment larger passage, passes through 4 sets of bed dies
Plate adds the template configuration mode combination subregion of 2 sets of side and roof arch to pour to add the scope of operation and optimize space, it is ensured that construction quality and
Construction speed is accelerated on the premise of safety.
Concrete stirring system is installed in inclined shaft near top, concrete mixing finishes that to be directly entered incline shaft transport special spacious
Mouthful chute enters inclined shaft bottom collecting bin buffering, then transports casting area to by delivery pump, it is possible to achieve concrete it is continuous
Transport, raising pours efficiency.
It can simultaneously be erected with previous set template using more a set of bed die with continuous placing, realize that continuous remove erects simultaneously
Mode accelerate the vertical speed of tearing open of template, improve the service efficiency and speed of perfusion of template.
Brief description of the drawings：
Fig. 1 is concrete inclined shaft structure for conveying of the invention.
Fig. 2 is subregion formwork for placing structure chart of the present invention.
Embodiment：
Such as Fig. 1, inclined shaft penetrates main hole from tunnel side, and the inclination angle of inclined shaft is to be provided with chute on 17-24 °, inclined shaft, on inclined shaft top
Concrete after concrete stirring system, mix is installed near portion gathering materials for inclined shaft bottom is entered by the chute installed on inclined shaft
Storehouse, collecting bin, which is more than below 2.5m3, collecting bin, installs delivery pump and two delivery pump bend pipes by concrete conveyance to two sections
Pouring in face, hole between the horizontal transport gradient -0.24% to 0.24% for tunnel, can be achieved to pump intermediate haulage up to 1.4km descendings,
Single pump relay is farthest up to 640m.Go out in hole in order to which the unimpeded selection section relatively for ensureing flexible transport passage is larger as conveying
The lay down location of pump, separate unit pumping distance no more than 600m.
Inclined shaft can also set two chutes, at this moment just realize the transport of concrete transportation grade separation by the setting of elevation and cut
Change.
The same scope of operation, which is set, when subregion is poured is no more than 200m.Each casting area uses four sets of end templates and two sets of sides
Arch template is poured, and it is as follows that specific subregion pours order：
First, reinforcing bar row is into after flowing water, end template and floor bow member that first first, one area of making pours storehouse, erect abutment wall bow member,
Sidewall template, installs arch bow member, arch template；
2nd, the end template and floor bow member that making second pours storehouse；
3rd, the first storehouse is poured；
4th, after solidifying, the sidewall template and arch template in a upper storehouse are removed, and is installed to next storehouse；The orlop template of making the 3rd
With bottom plate bow member；
5th, the second storehouse is poured；
6th, repeat step four, five is until poured the firstth area, and the whole moulds of dismounting are transported to next area.
7th, repeat step one to six, completes pouring for the secondth area and subsequent zone.
By this construction method, establish concrete inclined shaft sliding chute transportation, main tunnel pumping intermediate haulage, concrete subregion and pour
Build, the systemic construction system of template configuration mode.
