Abstract
This utility model relates to escape field, tunnel, it is specially a kind of high-impact tunnel pipe for escaping, use plastic/steel composite pipe, internal layer and the outer layer of this plastic/steel composite pipe are plastic material, intermediate layer is the anti-impact enhancement layer of metal or nonmetallic materials, all uses PUR to bond between intermediate layer and internal layer and outer layer.The beneficial effects of the utility model are: this high-impact tunnel escape tubing, weight is lighter, performance is more superior, it is more convenient, reliable to connect.Decrease the use of bolt in conventional connected mode, reduce labor intensity, deformation and anti-geology settling property superior.
Description
Technical field:
This utility model relates to escape field, tunnel, is specially a kind of high-impact tunnel pipe for escaping.
Background technology:
Widely available along with China railways and expressway construction, numerous construction projects along the line mainly take the mode of Tunnel Passing when passing through hills, mountain area, and tunnel excavating process is limited by the geologic structure of complexity, difficulty of construction and risk are high, the catastrophic failures such as landslide, roof fall easily occur.Issue about railway tunnel construction rescue instruction for this Ministry of Railways, it is desirable to during constructing tunnel, must be provided with passway for escaping.Passway for escaping may select steel pipe or pressure waved plastic pipe.The rigidity of steel pipe is good, but Unit Weight is big, poor toughness, mobile installation inconvenience.Pressure waved plastic pipe is then because of the steel-plastic structure of discontinuous phase, it is easy to ftractureed by rubble impact.Therefore select a kind of high impact properties, light, dismount simple high-impact tunnel pipe for escaping and be carried out national departments concerned suggestion, it is ensured that the basis of safe construction.
Utility model content:
This utility model is for the pipe for escaping shortcoming that steel pipe is master, it is provided that a kind of weight is lighter, performance is more superior, connect highstrenghtpiston's composite tunnel pipe for escaping more convenient, reliable.This pipe for escaping elastic deformation and anti-geology settling property are superior.
This utility model is achieved through the following technical solutions: a kind of high-impact tunnel pipe for escaping, use plastic/steel composite pipe, internal layer and the outer layer of this plastic/steel composite pipe are plastic material, intermediate layer is the anti-impact enhancement layer of metal or nonmetallic materials, all uses PUR to bond between intermediate layer and internal layer and outer layer.
Described anti-impact enhancement layer can use steel wire, steel skeleton or fibrous framework.
Between every pipe joint material, its connected mode is sleeve pipe bayonet joint, sleeve pipe material is consistent with compound plastic pipe, casing inner diameter is preferably greater than compound plastic pipe more than external diameter 50mm, some perforation it are provided with in junction, for connecting steel wire or steel wire penetrating, the position of perforation is at the inside 10cm-20cm of plastic composite pipe end face and box face.
Gap between sleeve pipe and tubing that this utility model uses is to adapt to field working conditions condition, it is simple to the bending of pipeline is laid.
The beneficial effects of the utility model are: this high-impact tunnel escape tubing, weight is lighter, performance is more superior, it is more convenient, reliable to connect.Decrease the use of bolt in conventional connected mode, reduce labor intensity, deformation and anti-geology settling property superior.

Detailed description of the invention
Embodiment: a kind of high-impact tunnel pipe for escaping, use plastic/steel composite pipe 5, the internal layer of this plastic/steel composite pipe 5 and outer layer are plastic material, and intermediate layer is the anti-impact enhancement layer 3 of metal or nonmetallic materials, and intermediate layer all uses hot melt adhesive layer 2 to bond with internal layer and the compound of outer layer；Described anti-impact enhancement layer 3 uses steel wire；Between every pipe joint material, its connected mode is sleeve pipe 6 bayonet joint, sleeve pipe material is consistent with compound plastic pipe, casing inner diameter is preferably greater than compound plastic pipe more than external diameter 50mm, some perforation 7 it are provided with in junction, for connecting steel wire or steel wire penetrating, the position of perforation 7 is at the inside 10cm-20cm of plastic composite pipe and box face.
During construction, first use grinding machine smooth anti-impact composite pipe material 5 end face part, at end face inwards 10-20cm arbitrary dimension, circumferencial direction angle bisecting also carries out bore position sign, carry out radial bore process, drilling hole amount circumferencial direction be not less than six, radial hole neglect scene greatly it needs to be determined that.Carrying out radial hole processing as the position that sleeve pipe 6 is corresponding with anti-impact composite pipe material 5, anti-impact composite pipe material 5 socket joint is to sleeve pipe 6 axial bore the most at last, uses steel wire cable both to be connected.
