Description
Technical field
The utility model belongs to mining tunnel field of engineering technology, relates to personnel escape's pipe in tunnel and tunnel, the anti-deformation quick Connector coupling of especially a kind of escape tube.
Background technique
The tunnel in tunnel and mine is in work progress, and due to the impact by complicated geology and other factors, happen occasionally landslide phenomenon, and landslide phenomenon of wherein closing the door consequence is the most serious, once there is the life safety that will have a strong impact on in-cavity construction personnel.Therefore, for the phenomenon of caving in tunnel, tunnel construction, for avoiding personnel casualty accidents as far as possible, reducing unnecessary economic loss, carrying out the setting of tunnel pipe for escaping, seem extremely important.
According to domestic associated documents requirement, tunnel V level country rock paragraph and be in the extremely high risk location of landslide and other locations when enclosing rock measure adds up to deform more than 100mm through risk assessment, must pipe for escaping be set, to guarantee the personal safety of workmen in tunnel excavating process.Between secondary lining and face, face must not be greater than apart from the safe step pitch between inverted arch the distance that design and specification specify.Between tunnel tunnel face and secondary lining, should arrange pipe for escaping, along with excavation drilling depth constantly moves forward, pipe for escaping distance excavation face should be not more than 20m, stretches into and applies inverted arch section and must not be less than 5 meters.
At present, what state's inner tunnel escape tube was the most frequently used is steel pipe, the steel pipe that job site uses exist easily be out of shape under impact load, per unit volume is heavy, interface is many, blow-by, Heavy Weight are difficult to the shortcomings such as carrying dismounting, to installing, using and the operation in later stage all exists inconvenience and causes the risk of potential safety hazard; Meanwhile, in smooth pipeline, certain impact be also result on the escape efficiency of escape personnel.Especially need to ensure, the connection between escape tube must have enough anti-deformation, stretching resistance, otherwise just loses the characteristic of escape tube.And the mode that existing employing flange bolt connects, tensile strength, ability of anti-deformation are all lower.
By retrieval, find following two sections of patent documents:
1, a kind of mine pipe for escaping of a kind of mine pipe for escaping (CN103806937A), along the tunnel in cutter's working surface, turnover face, omnidistance laying pipe for escaping, pipe for escaping is fixed on the side in tunnel, pipe for escaping internal height is 1-1.8 rice, width 0.7-1.5 rice, be as the criterion at least can hold a people, pipe for escaping is assembled by many sections of pipe sections splicings.
2 one kinds of pipe for escaping (CN203075492U), described pipeline is longitudinal ripple shape pipe structure, and pipeline is vertical is arranged on interior of building; Buffering ring set is equipped with in each bending place of pipeline; The pipe side wall be close to below buffering ring set processes emergency exits; The bottom mouth of pipe of pipeline is provided with wide-mouth structure.
Contrasted by technical characteristics, above-mentioned publication and the utility model application have relatively big difference.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the anti-deformation quick Connector coupling of escape tube of a kind of stretching resistance, anti-all directions deformation.
The technological scheme that the utility model technical solution problem adopts is:
The anti-deformation quick Connector coupling of a kind of escape tube, comprise escape tube and pipe joint, all coaxially abutted flange is shaped with in the both side ends of escape tube, coaxial mounting pipe joint between abutted flange, the two ends of the described pipe joint abutted flange made with escape tube is corresponding is all shaped with a joint flange, and the co-axial seal realized thus between pipe joint with escape tube docks; This pipe joint is the tubulose arched upward in centre.
And, the inboard all inboard metal flanges of coaxial package one of the joint flange made in pipe joint both sides, the uniform interval, outer rim position of this inboard metal flange is shaped with screw; Metal flange outside the inboard coaxial package one of the abutted flange that escape tube two ends are made, the screw that outside this, inboard metal flange of metal flange respective tube joint is made is all shaped with an oval through hole, in each oval through hole, all wear a clamping bolt, this clamping bolt makes inboard by thread engagement mode, the metal flange in outside coaxially connects mutually.
Of the present utility modelly with good effect be a little:
1, escape tube of the present utility model adopts HPDE high density polyethylene pipe, and compared with existing steel pipe, HPDE high density polyethylene pipe has suitable elasto plastic deformation, also has the superiority of easy to connect, long service life and resisting environmental stress and cracking simultaneously; In addition, the weight of pipe for escaping is effectively reduced, and is more conducive to the field erected of escape tube with tearing open and moves operation.
2, pipe joint of the present utility model adopts an arch rubber sleeve to be connected between two adjacent escape tube, abutted flange is adopted to carry out axial connection between arch rubber sleeve with HPDE escape tube, achieve docking site in omnibearing deformation such as axis, angle and transverse directions, what avoid that escape tube causes because of distortion comes off, damages, drastically increase the resistance to deformation of escape tube and tension, resistance to compression, anti-torsion ability, ensure that the Security of escape tube.
3, between pipe joint of the present utility model, equal specular is provided with a pair adpting flange, adopts the inner end adpting flange of bolt to hitch to be connected and fixed fast, improve the working efficiency of escape tube dismounting between often pair of adpting flange.
