Description
Technical field
This utility model relates to a kind of tubing, especially one and has interior outerplanar enhancing winding pipe.
Background technology
Structured wall popes be a kind of with high density polyethylene (HDPE) (HDPE) as raw material, use the structure-wall pipe material that compression molding or hot winding shaping process are made, universal architecture includes double-wall corrugated pipe and winding structure pipe.A kind of novel acidproof, anticorrosion of this tubing, resistance to compression, nontoxic environmental protection tubing, belong to environment-friendly and energy-efficient new high-tech product, be the optimal regeneration products such as pipe of cement, cast iron pipe, glass tubing, PVC-U corrugated tube.HDPE is high molecular polymer, makes structure-wall pipe material have good pliability and overall critical external compressive resistance ability, when using under having overweight load road surface, it is ensured that current safety.Due to the pliability of tubing, when there is the geological activity such as earthquake, Earth cave, pipeline damage loss can be reduced to minimum, improve the ability of public utility quake evaluation.Pipeline uses hollow structure, on the premise of saving material, improves the ring stiffness of tubing.In the application, under equal conditions use structured wall popes engineering reliability compared with traditional piping material all by raising, comprehensive benefit is obvious, the narrowest, building dense, underground utilities complicated and heavy traffic section and when Acidity of Aikalinity soil is laid, more superiority.
Owing to structured wall popes has many premium properties, this tubing municipal drainage, building outdoor drainage, the defeated draining in buried farmland, discharge of industrial wastes, road drainage, sewage treatment plant, sports ground Plaza Project draining and electrical telecommunication engineering etc. are extensively applied.In recent years, along with the wilderness demand to structured wall popes, and be some technological deficiencies before overcoming, occur in that many improvement for these technological deficiencies, as disclosed a kind of three wall corrugated tubes at the Chinese patent of application number 201110325573.8, including internal layer, surge layer and outer plastic layer, perhaps having good performance, but production and processing technology difficulty necessarily strengthens, outer layer is plastic layer poor flatness, and simple plastics reinforced effects is excessively poor, can not increase the ring stiffness of hollow structure pipe.
Summary of the invention
Goal of the invention of the present utility model is, overcomes the deficiency of art methods, it is provided that a kind of ring stiffness height, simple in construction, meter Chong Geng are light, economical environment-protective, convenient dilatory and roll, and backfills that safety is higher has interior outerplanar enhancing winding pipe when laying.
For achieving the above object, it is proposed that following technical scheme:
One has interior outerplanar enhancing winding pipe, includes internal layer, structure sheaf, enhancement layer, external coating；Described structure sheaf is arranged between internal layer and enhancement layer, and described enhancement layer voluble wrapping, outside structure sheaf, forms even curface；Described external coating through spiral winding cladding or integral coating on enhancement layer, formed there is interior outerplanar enhancing winding pipe tubing.
Hollow structure is formed between described structure sheaf and internal layer and enhancement layer.
Described structure sheaf can be double-wall corrugated pipe outer wall construction or carat pipe circular configuration.
The round tubular structure of described structure sheaf includes that protective layer and rigid layer, described rigid layer are arranged in protective layer.
Described enhancement layer is that plastic tape or cover moulds band or steel wire or metal tape.
Described plastic tape is PP band, PE band or PET strip etc..
Described covering is moulded band and is included that plastic straps and strengthening core, described strengthening core are arranged among plastic straps, and strengthening core is banding or the metal of wire, plastics, fiber or cloth.
Described covering is moulded band and is covered for fiber reinforcement and to mould band, including plastic straps and the long fibre of more than or fibre bundle.
Described long fibre or fibre bundle are glass fibre or polyester fiber.
Described external coating is that the plastic tape of extrusion molten condition is coated on enhancement layer through spiral winding cladding or integral extrusion.
The beneficial effect of this utility model:
The interior outerplanar enhancing winding pipe that has in this utility model is to be coated with one layer of enhancement layer and one layer of smooth external coating again at structure sheaf outer wall.Tubing is collectively constituted by smooth internal layer, structure sheaf, enhancement layer and smooth external coating.Compared with solid-wall pipe, have and save material, the advantage that lightweight, intensity is high, can meet higher use requirement and construction requirement.It is coated on tubing outermost composite strengthening layer, can draw easily and roll, outer wall ripple will not be occurred to rupture and cave in, compare tradition and there is the structured wall popes of out-of-flatness outer wall, backfill safety when this structure is laid higher.Strengthen the radial direction bearing capacity of hollow structure layer simultaneously, enhance the ring stiffness of winding pipe, it is possible to well ensure the stability of structure.
