Abstract
The hedging pipe for escaping laid at the construction field (site), belongs to highway engineering construction safety means technical field, for hedging of escaping in engineering construction.Its technical scheme is: it is made up of more piece double-wall steel bellows and multiple fixed mount, double-wall steel bellows adopts two corrugated steel pipe sleeve structures, light-duty foamed damping material is filled between two corrugated steel pipes, outer wall corrugated steel pipe correspondence parallel with trough with the crest of inwall corrugated steel pipe, the two ends of double-wall steel bellows are welded to connect flange, multiple fixed mount is placed on ground, and double-wall steel bellows is placed on fixed mount.Double-walled sandwich of the present utility model has powerful anti-pressure ability, and when there is the geological disasters such as landslide, the personnel of job site can flee from the scene of the accident by double-wall steel bellows, avoid casualties.The utility model has that structure is simple, assembling and lay convenient, non-damageable advantage, provides effective safety guarantee equipment for carrying out the engineering constructions such as tunnel in geological condition complex area.
Description
Technical field
The utility model relate to a kind of in the engineering construction such as newly built tunnels, mine the pipeline for hedging of escaping, belong to highway engineering construction safety means technical field.
Background technology
In the construction in newly built tunnels, mine, because geological condition is complicated and changeable, there is the possibility of landslide in work progress, if constructor cannot flee the scene in time, there will be casualties, cause major industrial accident.At present, at the passway for escaping of the job site Non-precondition in various tunnel, once there is the accidents such as landslide, part constructor is got lodged in tunnel, rescue personnel must excavate the cubic metre of earth and stone blocked as early as possible, rescues injured personnel, avoids the personnel of the inside because of anoxic, lack of water and meeting accident simultaneously.If arrange the hedging passway for escaping of high strength, convenient movement at the construction field (site), constructor can withdraw job site by passway for escaping rapidly, avoids the generation of personnel casualty accidents.
Utility model content
The technical problem that the utility model solves is to provide a kind of hedging pipe for escaping laid at the construction field (site), this hedging pipe for escaping can rapid-assembling, laying at the construction field (site), fleeing from the scene of the accident when there is the accidents such as landslide by pipeline for constructor, avoiding the accident that casualties occurs.
The technical scheme solved the problems of the technologies described above is:
A kind of hedging pipe for escaping laid at the construction field (site), it is made up of more piece double-wall steel bellows and multiple fixed mount, double-wall steel bellows adopts two corrugated steel pipe sleeve structures, light-duty foamed damping material is filled between outer wall corrugated steel pipe and inwall corrugated steel pipe, outer wall corrugated steel pipe correspondence parallel with trough with the crest of inwall corrugated steel pipe, the two ends welded flange of double-wall steel bellows, adjacent two joint double-wall steel bellowss are connected by flange bolt, multiple fixed mount is placed on ground, and double-wall steel bellows is placed on fixed mount.
The above-mentioned hedging pipe for escaping laid at the construction field (site), 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 steel bellows matches.
The beneficial effects of the utility model are:
The job site that the utility model is laid after being connected by more piece double-wall steel bellows, the double-walled sandwich of double-wall steel bellows has powerful anti-pressure ability, when there is the geological disasters such as landslide, although the earthwork and rock have been blocked and have been exported and be pressed on double-wall steel bellows, but the personnel being trapped in tunnel construction site can flee from the scene of the accident by double-wall steel bellows, the accident of casualties is avoided to occur.The utility model has that structure is simple, assembling and lay convenient, non-damageable advantage, can lay fast and remove, provide effective safety guarantee equipment for carrying out the engineering constructions such as tunnel in geological condition complex area.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;

In figure, mark is as follows: outer wall corrugated steel pipe 1, inwall corrugated steel pipe 2, flange 3, light-duty foamed damping material 4, bolt 5, fixed mount 6, circular groove 7.
Detailed description of the invention
The utility model is made up of more piece double-wall steel bellows and multiple fixed mount 6.
Show in figure, double-wall steel bellows adopts two corrugated steel pipe sleeve structures, by two of different-diameter corrugated steel pipe suits, fills light-duty foamed damping material 4, as polyurethane foam material between outer wall corrugated steel pipe 1 and inwall corrugated steel pipe 2.Outer wall corrugated steel pipe 1 correspondence parallel with trough with the crest of inwall corrugated steel pipe 2, to increase the compressive strength of double-wall steel bellows.
Show in figure, the two ends welded flange 3 of double-wall steel bellows, adjacent two joint double-wall steel bellowss are connected by the bolt 5 of flange 3 by high strength, and flange 3 adopts plane face flange.
Show in figure, double-wall steel bellows is placed on fixed mount 6, and the upper surface of fixed mount 6 is circular groove 7, and the radian of the radian of circular groove 7 and the excircle of double-wall steel bellows matches, and multiple fixed mount 6 is placed on ground.
Outer wall corrugated steel pipe 1 of the present utility model and inwall corrugated steel pipe 2 adopt galvanized pipe or black pipe.The pitch of waves 125-the 200mm of outer wall corrugated steel pipe 1 and inwall corrugated steel pipe 2, wave height 25-50mm, the steel plate thickness of double-wall steel bellows is 3-6mm, and caliber scope is 800-2000mm, the tube coupling length 2800-3100mm of double-wall steel bellows.
