Abstract
The utility model discloses a kind of non-excavating construction flexible pipe, comprise internal layer, anti-internal pressure layer and stretching resistance protective layer from the inside to the outside successively, described internal layer is high-density polyethylene layer, described anti-internal pressure layer by the Fiber Winding being impregnated with high density polyethylene (HDPE) at inner layer outer surface and solidification form; Described stretching resistance protective layer is high-density polyethylene layer, and in layer there is and the wire rope of pipeline axis parallel and optical cable implantation.The utility model has strong tensile strength, and what can realize one way 3 km runs through laying, also possesses the ability of cable signal transmission simultaneously; And structure is simple, cost of production is low.
Description
Technical field
The utility model relates generally to the flexible pipe for underground non-excavating construction.
Background technique
At present, the laying of the pipelines such as such as oil, gas, water, cable, telecommunication connection, chemical product conveying is all adopt traditional directly to dig the mode of burying, and difficulty of construction is large, and cycle long extreme influence pedestrian and vehicle pass-through.There is non-excavating construction mode pipeline installation abroad now, namely a vertical hoistway is only excavated every longer 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 traction of laying will be needed to run through, thus realizing laying.But in distraction procedure, the frictional force of pipeline and hole soil layer is very large, therefore adjacent well track pitch from the longest can not more than 1 km, the breakage otherwise pipeline can deform.
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing and deficiency, the purpose of this utility model there is provided a kind of non-excavating construction flexible pipe, have higher tensile strength, what can realize one way 3 km runs through laying, also possesses the ability of cable signal transmission simultaneously.
Technological scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of non-excavating construction flexible pipe, comprise internal layer, anti-internal pressure layer and stretching resistance protective layer from the inside to the outside successively, described internal layer is high-density polyethylene layer, described anti-internal pressure layer by the Fiber Winding being impregnated with high density polyethylene (HDPE) at inner layer outer surface and solidification form; Described stretching resistance protective layer is high-density polyethylene layer, and in layer there is and the wire rope of pipeline axis parallel and optical cable implantation.
As preferably, described anti-internal pressure layer is solidified by fiber band spiral wrap and forms.
As preferably, the material of described fiber band is that one or more shufflings in nylon fiber, polyester fibre, glass fibre form.
As preferably, described fiber band is formed side by side by multiply fiber.
Beneficial effect: compared with prior art, the utility model has strong tensile strength, and what can realize one way 3 km runs through laying, also possesses the ability of cable signal transmission simultaneously; And structure is simple, cost of production is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible pipe described in the utility model;
Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1.
Wherein, internal layer 1, anti-internal pressure layer 2, stretching resistance protective layer 3, wire rope 4, optical cable 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As Fig. 1 shows; a kind of non-excavating construction flexible pipe; comprise internal layer, anti-internal pressure layer 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 again after dipping polyethylene, the outer wall being wrapped in internal layer is in a helical pattern heating and curing and obtains anti-internal pressure layer.Synchronously implant wire rope and optical cable finally by extruder when the outer wall base polyethylene of anti-internal pressure layer, thus form stretching resistance protective layer, high-tensilely provide signal transmission capabilities carrying simultaneously.
