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, stating nylon buckles is waterproof nylon button.
Further, the draining tube end protrudes into weeper drain
The income effect of the utility model is:
1, the utility model is low in 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 period 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 with unit for individual
Integral heat insulation performance；
4, hot pin and blower provide temperature enough to ventilation duct not can guarantee 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 blower, guarantee drainage system under extremely cold weather condition
Do not freeze.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-5, the utility model is a kind of waterproof/drainage structure for tunnel in cold area ever-frozen ground section, including row
Water pipe 1, drainpipe 1 divide for longitudinal drainage pipe 4 and transverse drain 5, and multiple groups ventilation duct 3, multiple groups ventilation are equipped in drainpipe 1
It is connected between pipe 3 using nylon buckles 12, air film 2 is enclosed with outside drainpipe 1, ventilation duct 3 is communicated with connecting leg 14, connecting leg 14
The other end elevates above the soil, and hot pin 13 is equipped with around 14 other end of connecting leg, is communicated with transverse tube 8, transverse tube 8 and 9 phase of blower on connecting leg 14
Connection, transverse tube 8 are 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, the lead for pulling, extraction when being conveniently replaceable ventilation duct 3 are provided on 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 protruded into weeper drain 6
One concrete application of the present embodiment are as follows: be laid with ventilation duct 3 in 1 internal symmetry of drainpipe, the number of ventilation duct 3 can
Adjust, be connected between ventilation duct 3 using waterproof nylon button 12 according to the actual situation, ventilation duct 3 role be to provide with
The channel of outside air connection, so that air be allow 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 mentions by tunnel internal geothermal energy
High 1 temperature of drainpipe prevents water freezing in drainpipe 1 from blocking so that the temperature for guaranteeing drainpipe 1 more than solidification point, reaches
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 guarantee that temperature sets ventilation on solidification point inside 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 guarantees 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 blower 9, therefore vertical switch 11 is closed during 9 exhausting of blower, is usually opened；Laterally switch 7 then exists
Blower 9 open during exhausting, usually closes.The two is used cooperatively, to guarantee that Tunnel inner air and outer air normally circulates.
