Technical field
The present invention relates to tunnel in cold area engineering fields, and in particular to a kind of guarded drainage for tunnel in cold area ever-frozen ground section
Structure.
Background technology
The operation security of tunnel in cold area and waterproof/drainage structure are closely bound up, once failing, tunnel safety is waterproof/drainage structure
It can not ensure.During tunnel in cold area is constructed and is runed, the normal work of ever-frozen ground section waterproof/drainage structure is even more to seem outstanding
It is important.In permafrost region, if tunnel in cold area waterproof/drainage structure is unable to normal use, " booster " can be caused due to freezing, " is blocked up
Phenomena such as pipe ", occurs, and very big hidden danger is brought to tunnel in cold area operation.How to ensure that tunnel in cold area waterproof/drainage structure can have length
Phase military service performance is the problem of numerous scholars pay close attention to always.
From conventional angle, selection is inspected periodically and is repaired to tunnel in cold area ever-frozen ground section waterproof/drainage structure
Ensure that its normal use is very difficult, maintenance process needs to dig lining concrete, on the one hand time-consuming and laborious, another party
Face, Tunnel Stability can be influenced by digging concrete, dealt with improperly and very likely caused tunnel deformation, in some instances it may even be possible to tunnel be caused to lose
Surely cave in.Therefore design it is a kind of be not required in maintenance and maintenance dig lining cutting novel waterproof/drainage structure have extremely important meaning
Justice.
Invention content
It is an object of the invention to overcome the above-mentioned problems in the prior art, one kind is provided and is used for tunnel in cold area for many years
The waterproof/drainage structure of frozen soil section, not only cost is relatively low, is convenient for construction and installation, can ensure will not be because of water when underground water is discharged
Freeze to cause " booster " or " plugging " phenomenon, while safe facility is used as by hot pin and wind turbine, ensures extremely cold day gas bar
Drainage system does not freeze under part.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of waterproof/drainage structure for tunnel in cold area ever-frozen ground section, including drainpipe, the drainpipe are divided into longitudinal direction
Drainpipe and transverse drain are equipped with multigroup ventilation duct in the drainpipe, nylon buckles are used between multigroup ventilation duct
It is connected, air film is enclosed with outside the drainpipe, the ventilation duct is communicated with connecting leg, and the connecting leg other end stretches out ground
Face is equipped with hot pin around the connecting leg other end, is communicated with transverse tube on the connecting leg, the transverse tube is connected with wind turbine, described
Transverse tube, which is equipped with, laterally to be switched, and vertical tube is communicated on the transverse tube, and the vertical tube is equipped with vertical switch.
Further, the ventilation duct is pvc pipe.
Further, the lead for pulling is provided on the ventilation duct.
Further, the air film is made of semi-rigid plastic, and the air film is made of multiple air junior units.
Further, the laterally switch and vertical switch are ring flange switch.
Further, it is waterproof nylon button to state nylon buckles.
Further, the draining tube end stretches into weeper drain.
The present invention income effect be：
1, the present invention is of low cost, and ventilation duct and air film can be mass, very economical；
2, ventilation duct can designated position, air film can also wrap up in advance in pre-plugged to drainpipe before draining pipe construction
On the outside of drainpipe, installation synchronous with drainpipe improves construction convenience；
3, ventilation duct can be extracted out by lead when later stage ventilation duct occurs old damaged, the ventilation duct more renewed, and
The air film being covered on drainpipe, even if there is individual air film unit to destroy, nor affects on because being individual with unit
Integral heat insulation performance；
4, hot pin and wind turbine can not ensure to provide temperature enough to ventilation duct only according to natural air convection current as safe facility
When spending, temperature in hole can be improved by hot pin, cross-ventilation is reinforced by wind turbine, ensure drainage system under extremely cold weather condition
Do not freeze.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
As shown in Figs. 1-5, the present invention is a kind of waterproof/drainage structure for tunnel in cold area ever-frozen ground section, including drainpipe
1, drainpipe 1 divides for longitudinal drainage pipe 4 and transverse drain 5, and multigroup ventilation duct 3, multigroup ventilation duct 3 are equipped in drainpipe 1
Between be connected using nylon buckles 12, be enclosed with air film 2 outside drainpipe 1, ventilation duct 3 is communicated with connecting leg 14, and connecting leg 14 is another
One end is elevated above the soil, and hot pin 13 is equipped with around 14 other end of connecting leg, is communicated with transverse tube 8 on connecting leg 14, transverse tube 8 is connected with wind turbine 9
It connects, transverse tube 8 is equipped with laterally switch 7, and vertical tube 10 is communicated on transverse tube 8, and vertical tube 10 is equipped with vertical switch 11.
Wherein, ventilation duct 3 is pvc pipe.
Wherein, it is provided with the lead for pulling on ventilation duct 3, is extracted out when being conveniently replaceable ventilation duct 3.
Wherein, air film 2 is made of semi-rigid plastic, and air film 2 is made of multiple air junior units, can prevent air
Film 2 is punctured.
Wherein, laterally switch 7 and vertical switch 11 are ring flange switch.
Wherein, nylon buckles 12 are waterproof nylon button 12.
Wherein, 1 end of drainpipe is stretched into weeper drain 6.
One of the present embodiment has particular application as：It is laid with ventilation duct 3 in 1 internal symmetry of drainpipe, the number of ventilation duct 3 can
Adjusted according to actual conditions, between ventilation duct 3 using waterproof nylon button 12 be connected, 3 role of ventilation duct be to provide with
The channel of outside air connection, to allow air to circulate, by cross-ventilation principle, relative density is small in tunnel
Hot-air carries out flowing by ventilation duct 3 with cold air relatively denser outside hole and exchanges, and is carried by tunnel internal geothermal energy
1 temperature of high drainpipe, for the temperature to ensure drainpipe 1 more than solidification point, reaching prevents water freezing in drainpipe 1 from blocking
The phenomenon that.Ventilation duct 3 is laid in inside drainpipe 1, abuts 1 inner wall of drainpipe, and ventilation duct 3 is pvc pipe, and matter is soft bent, because
This can be pulled out when ventilation duct 3 damages by lead, to ensure that temperature sets ventilation inside on solidification point in drainpipe 1
While pipe 3, outside drainpipe 1 wrap up one layer of air film 2, play thermal insulation function, when tunnel inner air and outer air convection current without
When method ensures that drainpipe 1 is not frozen, temperature can be improved by hot pin 13, when normal ventilation can meet required temperature item
Under part, without opening wind turbine 9, therefore vertical switch 11 is closed during 9 exhausting of wind turbine, is usually opened；Laterally switch 7 then exists
Wind turbine 9 opened during exhausting, usually closes.The two is used cooperatively, to ensure that Tunnel inner air and outer air normally circulates.
