Description
Technical field
The utility model belongs to escape field, more particularly to a kind of stent-type adjustable angle pipe for escaping.
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.
Occur that the tunnel height of different depth is different, it is necessary to which pipe for escaping carries out certain angle during pipeline construction
Turn, escaped with adapting to tunnel operating mode, existing pipe for escaping, which is realized, turns typically using the side of delivering of similar water pipe
Formula is carried out, and operation is inconvenient, and is more not suitable for the turning in the shorter tunnel of length.
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 structure is novel, easy to adjust
Stent-type adjustable-angle pipe for escaping.
The utility model adopts the technical scheme that：
A kind of stent-type adjustable angle pipe for escaping, including support and pipe for escaping, the support include two it is parallel
Carriage, carriage top interval are formed with three through holes, and carriage side wall is formed with pin-and-hole corresponding to the through hole in both sides, in both sides
Through hole in coaxially slide two slide bars are installed, slide bar is also formed with pin-and-hole, and bearing pin is real coaxially through in the pin-and-hole of carriage and slide bar
The positioning of existing slide bar and carriage, is co-axially mounted adjusting rod, adjusting rod side is formed with engaging tooth, in centre in the through hole of centre
Through hole side carriage in hinge dress engagement wheel, engagement wheel engage with the engaging tooth on adjusting rod, and rotation is engaged to take turns and adjusted
The height of adjusting rod, engagement wheel are coaxially fixedly mounted with one handle.
Moreover, being fixedly mounted with a fastener jointly in the upper end end of adjusting rod and two slide bars, support centriciput is formed with V-shaped groove,
For being embedded in pipe for escaping, two symmetrical sides of V-shaped groove, which are respectively symmetrically cut with scissors, fills a fan-shaped regulation ear, and system is spaced on regulation ear
There are multiple positioning holes, be also formed with multiple positioning holes, regulation ear and branch fastener diverse location corresponding to multiple positioning holes on branch fastener
Positioning hole it is coaxially corresponding after, be co-axially inserted positioning locating rod.
The advantages of the utility model and good effect are：
Stent-type adjustable angle pipe for escaping provided by the utility model includes the support that a height on both sides can be adjusted,
Can be with the length of quick regulation branch fastener by crank, and then the angle of pipeline is adjusted, it is adapted to the tunnel of different height
Angle requirement, it is applied widely.
The branch fastener of stent-type adjustable angle pipe for escaping provided by the utility model has two regulation ears, adjusts two tune
Section ear can adapt to the support of the pipeline of different-diameter, ensures different needs, after uniformly doing a support, while adapts to difference
Operating mode.
