Abstract
The invention discloses a kind of non-excavating construction flexible duct; include internal layer, anti-interior shell of compression and stretching resistance protective layer from the inside to the outside successively; described internal layer is high-density polyethylene layer, and described anti-interior shell of compression is formed at inner layer outer surface solidification by the Fiber Winding being impregnated with high density polyethylene (HDPE)；Described stretching resistance protective layer is high-density polyethylene layer, and is implanted with the steel wire rope with pipeline axis parallel and optical cable in layer.The present invention has strong tensile strength, and what can realize one way 3 km runs through laying, is also equipped with the ability of cable signal transmission simultaneously；And simple in construction, production cost are low.
Description
Technical field
The invention mainly relates to the flexible duct for underground non-excavating construction.
Background technology
At present, for instance the laying of the pipelines such as oil, gas and water, cable, telecommunication connection, chemicals conveying is all adopt traditional directly to dig the mode of burying, and difficulty of construction is big, and cycle long extreme influence pedestrian and vehicle pass-through.Now non-excavating construction mode pipeline installation occurs abroad, namely a vertical hoistway is only excavated every relatively long distance, and cut a hole borehole hole by excavator in the horizontal direction at underground certain depth, bounce back again after drilling through and the pipeline laid traction will be needed to run through, thus realizing laying.But in distraction procedure, the frictional force of pipeline and hole soil layer is very big, and therefore adjacent well track pitch not can exceed that 1 km from the longest, otherwise pipeline can deform breakage.
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing and deficiency, it is an object of the invention to provide a kind of non-excavating construction flexible duct, has had higher tensile strength, and what can realize one way 3 km runs through laying, is also equipped with the ability of cable signal transmission simultaneously.
Technical scheme: for achieving the above object; the present invention is by the following technical solutions: a kind of non-excavating construction flexible duct; include internal layer, anti-interior shell of compression and stretching resistance protective layer from the inside to the outside successively; described internal layer is high-density polyethylene layer, and described anti-interior shell of compression is formed at inner layer outer surface solidification by the Fiber Winding being impregnated with high density polyethylene (HDPE)；Described stretching resistance protective layer is high-density polyethylene layer, and is implanted with the steel wire rope with pipeline axis parallel and optical cable in layer.
As preferably, described anti-interior shell of compression is formed by the solidification of fiber band spiral wrap.
As preferably, one or more shufflings that the material of described fiber band is in nylon fiber, polyester fiber, glass fibre form.
As preferably, described fiber band is formed side by side by multiply fiber.
Beneficial effect: compared with prior art, the present invention has strong tensile strength, and what can realize one way 3 km runs through laying, is also equipped with the ability of cable signal transmission simultaneously；And simple in construction, production cost are low.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible duct of the present invention；
Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1.
Wherein, internal layer 1, anti-in shell of compression 2, stretching resistance protective layer 3, steel wire rope 4, optical cable 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention, after having read the present invention, the amendment of the various equivalent form of values of the present invention is all fallen within the application claims limited range by those skilled in the art.
As Fig. 1 shows; a kind of non-excavating construction flexible duct; include internal layer, anti-interior shell of compression and stretching resistance protective layer from the inside to the outside successively; described internal layer is that high density polyethylene (HDPE) is made; then multiply nylon fiber is arranged into band then through after dipping polyethylene, be wrapped in a helical pattern on the outer wall of internal layer and be heating and curing obtain anti-in shell of compression.Synchronizing implantation steel wire rope and optical cable during finally by the outer wall base polyethylene of extruder shell of compression in anti-, thus forming stretching resistance protective layer, high-tensile providing signal transmission capabilities carrying simultaneously.
Claims (4)
1. a non-excavating construction flexible duct; it is characterized in that: include internal layer, anti-interior shell of compression and stretching resistance protective layer from the inside to the outside successively; described internal layer is high-density polyethylene layer, and described anti-interior shell of compression is formed at inner layer outer surface solidification by the Fiber Winding being impregnated with high density polyethylene (HDPE)；Described stretching resistance protective layer is high-density polyethylene layer, and within resisting, the outer wall of shell of compression synchronizes to be implanted with the steel wire rope with pipeline axis parallel and optical cable when extruding high density polyethylene (HDPE).
2. non-excavating construction flexible duct according to claim 1, it is characterised in that: described anti-in shell of compression solidified by fiber band spiral wrap and form.
3. non-excavating construction flexible duct according to claim 2, it is characterised in that: one or more shufflings that the material of described fiber band is in nylon fiber, polyester fiber, glass fibre form.
