Description
Technical field
The utility model relates to a kind of tubing, and especially one is covered and moulded band enhancing hollow spiral tube.
Background technique
Hollow spiral tube be a kind of with high density polyethylene (HDPE) (HDPE) for raw material, adopt the structure-wall pipe material that hot winding shaping process is made, a kind of novel acidproof, anticorrosion, resistance to compression of this tubing, nontoxic environmental protection tubing, belonging to environment-friendly and energy-efficient new high-tech product, is the optimal update products such as cement pipe, cast iron tube, glass tube, PVC-U bellows.HDPE is high molecular polymer, makes hollow spiral tube material have good pliability and overall critical external compressive resistance ability, have use under overweight load road surface time, current safety can be ensured.Due to the pliability of tubing, when there is the geological activity such as earthquake, Earth cave, can pipeline damage loss be reduced to minimum, improve the ability of public facilities quake evaluation.Pipeline adopts winding process shaping, under the prerequisite of saving material, improves the ring stiffness of tubing.High density polyethylene (HDPE) has the ability that extremely strong corrosion-resistant and chemically resistant material corrodes, need not any preservative treatment when carrying corrupt liquid or laying in the extremely strong soil of corrosivity, and performance is better than other tubing greatly.Due to the ageing-resistant performance of its excellence, use as buried pipeline, the working life of 50 years can be guaranteed.High density polyethylene (HDPE) winding structure wall pipe does not add any auxiliary agent in course of working, and 100% uses high density polyethylene (HDPE) without any toxicity, non-scaling, not propagate microorganisms.Product in process of production cooling water circulation uses, and environmentally safe produce are raw, and the waste and old pipeline with the trade mark can 100% recycling.Hollow spiral tube material inwall roughness N is about 0.010, therefore carry fluid time specific frictional resistance little, under equal service condition carrying capacity comparatively cement pipe can increase substantially.Therefore the hollow spiral tube that available internal diameter is less substitutes the larger cement pipe of internal diameter, reduces engineering cost.Inner tube wall roughness is low, carrying capacity is large, in the application, use the reliability of hollow spiral tube engineering all will improve compared with traditional piping material under equal conditions, comprehensive benefit is obvious, the particularly complicated and heavy section of narrow, building dense, underground utility and when pH value soil is laid on construction ground, has more superiority.
Because hollow wound pipe has many premium properties, this tubing is applicable to the municipal drainage of conveying coolant-temperature gage below 45 DEG C, building outdoor drainage, the defeated draining in buried farmland, discharge of industrial wastes, road drainage, sewage treatment works, the draining of sports ground Plaza Project and electrical telecommunication engineering etc.In recent years, along with the wilderness demand to hollow wound pipe, and be some technological deficiencies before overcoming, many improvement for these technological deficiencies are there is, as disclosed a kind of HDPE at the Chinese patent of application number 200610021292.2, PVC plastic plastic composite winding pipe, comprise rectangle hollow band and HDPE plastic obturator formation, the tube wall of described rectangle hollow band is the PVC plastic bed of material from inside to outside respectively, composite tack coat and HDPE plastic layer, have employed multilayer labyrinth, perhaps there is good performance, but production and processing technology difficulty must strengthen, and multilayer labyrinth is unfavorable for ensureing the quality of production.And for example application number be 201210192872.3 Chinese patent disclose a kind of fiberglass reinforced HDPE binary wall twisting and pipe, the hollow square tube extruded after being mixed with continuous glass-fiber by HDPE raw material is wound, mainly extrude the improvement of raw material, but glass fibre mixes with plastics, uniformity is difficult to ensure, and when extruding, tube wall smoothness must be affected.And for example application number is that the Chinese patent of 201310001048.X discloses a kind of fiberglass reinforced hollow wall polyethylene wound pipe, is wound, but is synchronously wound with at least one PP/PE compound coating roving glass fiber bundle when hot melt adhesive is welded by hollow square tube; Reinforcing glass fiber is arranged in hot melt adhesive, is difficult to ensure that it has enhancing effect, the ring stiffness of hollow square tube can not be strengthened.
Summary of the invention
Goal of the invention of the present utility model is, overcomes the deficiency of art methods, provides that a kind of ring stiffness is high, structure is simple, meter Chong Geng is light, and production technology is simple, and the covering of economical environment-protective is moulded band and strengthened hollow spiral tube.
For achieving the above object, following technological scheme is proposed:
One is covered and is moulded band enhancing hollow spiral tube, comprises square tube, melts glue, covers and mould band; Cover and mould band and be longitudinally placed in one of them side of square tube or both sides and formed to cover and mould band and strengthen square tube, described in cover and mould band and strengthen square tube and be arranged on spiral winding on drum die, and melt glue bond gap by extruding molten, thus formed to cover and mould band and strengthen hollow spiral tube.This covers moulds the both sides that band is arranged on hollow square tube, strengthen the radial rigidity of hollow square tube, obviously can be good at strengthening the ring stiffness of entwining tube, and cover and mould band and be set to unpack format, can be good at ensureing the stability of structure, and many groups can be arranged as required cover and mould band.
Described covering is moulded band and is comprised plastic straps and reinforced core, and described reinforced core is arranged among plastic straps, and reinforced core is metal, plastics, fiber, cloth etc. that be banded or wire.
Described covering is moulded band and is covered for fiber reinforcement and mould band, and comprise plastic straps and some long fibres, long fibre is arranged among plastic straps; Described long fibre can be glass fibre, polyester fibre etc.
Described covering is moulded band and is moulded band for Reinforced by Metal covers, and wherein draw together plastic straps and metal tape, described metal tape is arranged among plastic straps; Described metal tape can be steel band, aluminium strip etc.
Described plastics can be polypropylene, polyethylene and composition thereof or hot melt adhesive or other plastics.
The beneficial effect of this model utility:
Covering in the utility model is moulded band and is strengthened hollow spiral tube and be provided with to cover in the both sides of hollow square tube and mould band, strengthen the radial bearing capacity of hollow square tube, enhance the ring stiffness of entwining tube, and cover and mould band and be set to unpack format, can be good at ensureing the stability of structure, and many groups can be arranged as required cover and mould band.Further, this provides to cover and moulds band and strengthen that hollow spiral tube structure is simple, meter Chong Geng light, and production technology is simple, has the feature of energy-conserving and environment-protective.
