Abstract
It the utility model is related to a kind of pipe for escaping end protection cap; including circular cross-section baffle plate; in circular cross-section baffle plate; flashing light is installed in a middle side part of circular cross-section baffle plate; uniform four handles on the circular cross-section baffle plate of flashing light opposite side; coaxially integrally extend the ring arc sheath for being formed with and axially being bent to flashing light side in the outer rim of circular cross-section baffle plate; ring arc sheath can protect the end outer rim of pipe for escaping; four fixations are installed in the inner side of ring arc sheath to grab, grabbing middle part in four fixations is formed with arc bending arc.Pipe for escaping end provided by the utility model protection cap integrally makes the bending sheath of a radial direction, the pipe for escaping edge of fragility can effectively be prevented into pipeline breaking caused by the surprise attack of rubble, means of escape is safer, ensures life channel.
Description
Technical field
The utility model belongs to protection field, more particularly to a kind of pipe for escaping end protection cap.
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 pipe for escaping end protection
Lid.
The utility model adopts the technical scheme that：
A kind of pipe for escaping end protection cap, including circular cross-section baffle plate, in circular cross-section baffle plate, in circular cross-section baffle plate
A middle side part installation flashing light, uniform four handles on the circular cross-section baffle plate of flashing light opposite side, circular cross-section keep off
Coaxially integrally extension is formed with the ring arc sheath axially bent to flashing light side to the outer rim of plate, and ring arc sheath, which can be protected, to be escaped
The end outer rim of raw pipeline, installs four fixations in the inner side of ring arc sheath and grabs, and grabbing middle part in four fixations is formed with curved bend
Roll over arc.
Moreover, axial fin is formed with arc is grabbed.
The advantages of the utility model and good effect are：
Pipe for escaping end provided by the utility model protection cap integrally makes the bending sheath of a radial direction, can will be crisp
Weak pipe for escaping edge, effectively prevents pipeline breaking caused by the surprise attack of rubble, and means of escape is safer, ensures that life leads to
Road.
Brief description of the drawings
Fig. 1 is the structural representation of support.
Fig. 2 is Fig. 1 A-A to sectional view.
Fig. 3 is use state figure.
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 end protection cap, including circular cross-section baffle plate 3, in circular cross-section baffle plate, kept off in circular cross-section
The middle side part installation flashing light 2 of plate, uniform four handles 5 on the circular cross-section baffle plate of flashing light opposite side, cuts in circle
Coaxially integrally extension is formed with the ring arc sheath 1 axially bent to flashing light side to the outer rim of face baffle plate, and ring arc sheath can
The end outer rim of pipe for escaping is protected, four fixations are installed in the inner side of ring arc sheath and grab 4, grabbing middle part in four fixations is formed with
Arc bends arc 6, and the sealing ring for being embedded in pipe for escaping extends out arc.
In order to further enhance the fixed intensity grabbed, axial fin is formed with arc is grabbed.
Four fixations in the application grab can be inlaid in when mounted setting-in pipe for escaping sealing ring extend out on arc, by
In being all arcuate structure, it is very easy to remove, improves escape efficiency.
Claims (2)
