Abstract
It the utility model is related to a kind of pipe for escaping with high-elastic protective jacket, including body, body one end is connection end, connection end is integrated the radial direction extension diameter section made, and the internal diameter of extension diameter section is equal to former outer diameter tube, bulge loop is formed with extension diameter section, embedded sealing ring in bulge loop, front of motor between adjacent channel coaxially comes in and goes out to the connection end of another pipeline, and in body connection end foreign aid's coaxial package rubber sleeve, the rubber sleeve surfaces externally and internally is uniform ripple glaze.Pipe for escaping provided by the utility model with high-elastic protective jacket can effectively avoid being injured by a crashing object by rubble or machinery in the rubber sleeve of arrival end coaxial package one of existing pipe for escaping, effectively protect pipe for escaping entrance, there is provided working security.
Description
Technical field
The utility model belongs to protection field, more particularly to a kind of pipe for escaping with high-elastic protective jacket.
Background technology
The tunnel in tunnel and mine, due to being influenceed by complicated geology and other factorses, happens occasionally in work progress
Landslide phenomenon, wherein landslide phenomenon consequence of closing the door is the most serious, once occur to have a strong impact on that the life of in-cavity construction personnel is pacified
Entirely.Therefore, for the phenomenon of caving in tunnel, constructing tunnel, to avoid personnel casualty accidentses as far as possible, unnecessary warp is reduced
Ji loss, carries out the setting of tunnel pipe for escaping, it appears extremely important.
Required according to domestic associated documents, tunnel V level country rock paragraphs and the ground that the high risk that collapses is in through risk assessment
Section and other locations are when enclosing rock measure adds up to deform more than 100mm, it is necessary to pipe for escaping are set, to ensure tunnel excavating process
The personal safety of middle workmen.Between secondary lining and face, face cannot be greater than away from the safe step pitch between inverted arch
Distance as defined in design and specification.Between tunnel tunnel face and secondary lining, pipe for escaping should be set, with excavation drilling depth not
Disconnected reach, pipe for escaping distance, which excavates face, should be not more than 20m, stretch into and applied inverted arch section and cannot be less than 5 meters.
The end of a pipe for escaping part the most fragile, how to protect the entrance termination of pipe for escaping turns into means of escape
The main task of protection.
Utility model content
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided a kind of protection structure is simple, protection
Sufficiently carry the pipe for escaping of high-elastic protective jacket.
The utility model adopts the technical scheme that：
A kind of pipe for escaping with high-elastic protective jacket, including body, body one end are connection end, and connection end is integrated system
The radial direction extension diameter section gone out, the internal diameter of extension diameter section are equal to former outer diameter tube, and bulge loop is formed with extension diameter section, and setting-in seals in bulge loop
Enclose, the front of motor between adjacent channel coaxially comes in and goes out to the connection end of another pipeline, it is characterised in that：Outside body connection end
Coaxial package rubber sleeve is helped, the rubber sleeve surfaces externally and internally is uniform ripple glaze.
Moreover, one layer of reinforcement layer of cloth can also be pressed in the middle part of the side wall of rubber sleeve.
Moreover, the coaxial circle of stickup one sealing strip of inwall in body connection end and the junction of front of motor.
The advantages of the utility model and good effect are：
Pipe for escaping provided by the utility model with high-elastic protective jacket is coaxial in the arrival end of existing pipe for escaping
A rubber sleeve is set with, can effectively avoid being injured by a crashing object by rubble or machinery, effectively protects pipe for escaping entrance, there is provided construction safety
Property.
Pipe for escaping provided by the utility model with high-elastic protective jacket is in pipe head and the company of pipeline flat segments
Connect place inner edge and paste a circle sealing strip, after preventing pipeline from connecting, the rounding off of two pipeline junctions can be ensured, conveniently escaped
It is raw, also it can effectively prevent the toxic gas in pipeline to be filled into pipeline.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is a kind of structural representation of rubber sleeve.
Embodiment
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, it is impossible to limit the scope of protection of the utility model with following embodiments.
A kind of pipe for escaping with high-elastic protective jacket, including body 1, body one end are connection end 4, and connection end is integrated
The radial direction extension diameter section made, the internal diameter of extension diameter section are equal to former outer diameter tube, and bulge loop is formed with extension diameter section, and setting-in seals in bulge loop
Circle 5, the front of motor between adjacent channel coaxially come in and go out to the connection end of another pipeline, realize the connection of pipe for escaping.
The innovation of the application is：
Foreign aid's coaxial package rubber sleeve 3 in body connection end, the rubber sleeve surfaces externally and internally are uniform ripple glaze.
One layer of reinforcement layer of cloth 6 can also be pressed in the middle part of the side wall of rubber sleeve, can be aramid fabric, glass fiber etc..
The coaxial circle of stickup one sealing strip 2 of inwall in body connection end and the junction of front of motor, prevents pipeline from connecting
Afterwards, the rounding off of two pipeline junctions can be ensured, convenient escape, also can effectively prevent the toxic gas in pipeline from filling out
It is charged in pipeline.
