Abstract
The invention discloses an escape pipeline which comprises a plurality of sections of double-wall corrugated pipes. The structure that two corrugated pipe bodies arranged in a sleeving manner is adopted for each section of double-wall corrugated pipe, wherein the part between the outer-wall corrugated pipe body and the inner-wall corrugated pipe body is filled with a light foaming buffering material, and crests and troughs of the outer-wall corrugated pipe body and the inner-wall corrugated pipe body are parallel and correspond to each other. A connecting piece is arranged at the two ends of every two adjacent sections of double-wall corrugated pipes for fixing and comprises a first flange, a second flange and a clamp, wherein the first flange and the second flange are in butt joint, and the clamp surrounds the outer circumference of the flanges and is used for fixing the first flange and the second flange. Each clamp is formed by two assembled semicircular structures, wherein the two semicircular structures are fastened through a bolt, and grooves used for assembling the radial protruding edges of the first flange and the second flange are formed in the inner circumference of the clamp. The structure of the escape pipeline has high compression resistance, each section of pipe has stable connecting performance, installation is convenient and fast, and labor cost is reduced.
Description
Technical field
The present invention relates to a kind of escape refuge apparatus, specifically a kind of pipe for escaping.
Background technology
In the work progresss such as newly built tunnels, mine, railway, highway construction in recent years, due to the situation of complex geologic conditions, difficulty of construction is large, construction risk is high, very easily there is the catastrophic failures such as landslide, roof fall, prominent mud water burst, if constructor cannot flee the scene in time, there will be casualties, cause major industrial accident.Existing passway for escaping is generally steel pipe, is easily out of shape under impact load, there is the shortcomings such as unit volume weight, blow-by.
Summary of the invention
The object of this invention is to provide a kind of pipe for escaping, this pipe for escaping structure described has powerful anti-pressure ability, and every pipe joint material has stable connectivity, quick and easy for installation, reduces cost of labor.
For achieving the above object, the technical solution used in the present invention is: a kind of pipe for escaping, described pipeline comprises more piece double-wall corrugated pipe composition, double-wall corrugated pipe adopts two bellows-sheathed assembling structures, light-duty foamed damping material is filled between outer wall bellows and inwall bellows, outer wall bellows correspondence parallel with trough with the crest of inwall bellows, the two ends of adjacent two joint double-wall corrugated pipes arrange connector and fix, and described connector comprises the first flange and second flange of docking setting and is looped around flange excircle week for fixing the clip of the first flange and the second flange; The end that connects of described first flange and the second flange is respectively arranged with the radial flange stretching to clip; Described clip is two semicircular structures be equipped with mutually, and described two semicircle clips are fastened by bolts, and the inner periphery of described clip are provided with the groove of equipped first flange and the second flange radial flange.
Further, described bellows lower end is also provided with multiple fixed mount.
Further, the upper surface of described fixed mount is circular groove, and the radian of the radian of circular groove and the excircle of double-wall corrugated pipe matches.
Further, the two ends of described upper semi-circle clip are provided with two limited impressions, and the two ends of lower half circle clip are provided with two spacing block sets, and described limited impression matches with spacing block set.
The invention has the beneficial effects as follows: the double-walled sandwich of double-wall corrugated pipe has powerful anti-pressure ability, when there is geological disaster, although the earthwork and rock have been blocked and have been exported and be pressed on double-wall corrugated pipe, but the personnel being trapped in tunnel construction site can flee from the scene of the accident by double-wall corrugated pipe, the accident of casualties is avoided to occur; Described more piece bellows adopts the form of structure of the supporting flange of clip, both facilitates attended operation, and can ensure again the connectivity robustness of pipe for escaping joint, be more conducive to on-the-spot safe handling, quick and easy for installation, reduce cost of labor.
