Abstract
The invention relates to a steel and plastic composite structure wall pipeline, and the pipeline is formed by spiral winding of steel and plastic composite T-shaped strips and welding and connecting by hot melt adhesive, thus forming the U-shaped structure wall pipeline which has stiffeners. The pipeline has the advantages of reasonable structure, saving materials, solid welding by the melt adhesive, high ring stiffness, etc.
Description
Technical field
The present invention relates to a kind of drainage pipe, relate in particular to a kind of steel plastic composite structure wall tube and preparation method thereof.
Background technique
At present, the tubing that domestic underground water supply and drainage pipe-line system is used mainly contains concrete pipe, concrete reinforced pipe and cast iron tube, because it is bigger than length and vehicle flowrate that it builds the time limit, the buried concrete waste pipe in some highway section and cast iron water pipe are damaged in succession aging, cause municipal drainage to stop up, the water pipe explosion, not only bring inconvenience to citizen's life, and because of working procedure complicated, the pipe joint number is more, leakage proof is difficult in time handling, accumulate over a long period and not only can cause road foundation to sink, effluent seepage, also can pollute soil property, the water source becomes public hazards.For this reason, adopt have good withstand voltage, light weight, corrosion-resistant, environment protection type tubing become the task of top priority.
Recent years, all types of plastic tubing rises gradually at home, and progressively replaces concrete pipe, concrete reinforced pipe and cast iron tube.With respect to material in the past, the advantage of plastic tube is that quality is obviously light under identical withstand voltage condition, and corrosion-resistant, low pollution or pollution-free.In the long run/term, plastic tube is also longer working life.Advocate at home under the overall situation of environmental protection, saving, all types of plastic tubing is dominated the market rapidly.And plastic tube also has the narrow limitation of oneself, just has been difficult to guarantee ring stiffness when bore reaches 800mm.
Summary of the invention
Purpose of the present invention in order to overcome the problems referred to above that prior art exists, provides a kind of steel plastic composite structure wall tube with new structure exactly.
The object of the present invention is achieved like this: a kind of steel plastic composite structure wall tube, and mould compound T type band spiral by steel and twine and be made of welded connection with hot melt adhesive, form U-shaped structural walls pipeline with stiffening rib.
The horizontal edge both sides that described steel is moulded compound T type band are provided with bridging arrangement.
Steel plastic composite structure wall tube of the present invention makes it compared with prior art owing to adopted above technological scheme, have following advantage and and characteristics:
1, tube wall is a U shaped steel plastic composite structure wall, under the identical situation of ring stiffness, saves big content of starting materials than solid wall pipe;
2, tubing generally adds other auxiliary agents by high density polyethylene (HDPE) and makes, and light weight is convenient to transportation and is installed;
3, tubing belongs to flexible pipe, and good toughness is shock-resistant;
4, inner tube wall is level and smooth, and under same gradient construction conditions, flow, flow velocity binomial index value all are higher than concrete pipe, thereby can be less than concrete pipe on the tubing specification is selected;
5, have good toughness and plasticity, dry concrete pipe and flexible PVC pipe all can't be by comparison;
6, water tightness is good, adopts steel to mould socket joint connection in the composite elastic sealing, and sewage does not leak outside in can guaranteeing to manage, and can comply with asymmetry settlement of foundation, can not produce the disconnection phenomenon of rupture of concrete pipe.。
Description of drawings
The sectional structure schematic representation of Fig. 1 steel plastic composite structure wall tube of the present invention;
Fig. 2 moulds the sectional structure schematic representation of compound T type band for the steel among the present invention.
Embodiment
Referring to Fig. 1, Fig. 2, steel plastic composite structure wall tube of the present invention is moulded compound T type band 1 spiral by steel and is twined and be made of welded connection with hot melt adhesive 2, and formation has the U-shaped structural walls pipeline of stiffening rib.The horizontal edge both sides that steel is wherein moulded compound T type band 1 are provided with bridging arrangement 11.
The structure wall thickness of steel plastic composite structure wall tube of the present invention can be by adjusting the internal mold rotational speed control of forming machine, and spiral angle and roundness can be by adjusting the internal mold angle of swing control of forming machine.
Extruding pipe among the present invention is that steel is moulded compound T type pipe.Than all the other riffled tubes, can not only guarantee ring stiffness well, also possessed the advantage that plastic tube possessed, can be used for making large diameter pipeline.
The pipeline structure because of with pressure-bearing direction (being generally level or vertical) several angle being arranged, has slowed down pressure to the helix structure that is tilt fixing to a certain extent, compares with the straight burr pipeline of directly extruding, and is not prone to the disconnection phenomenon of rupture.
Below be two embodiments of steel plastic composite structure wall tube of the present invention:
Embodiment 1
Sampling 300SN8 pipeline, internal diameter of the pipeline 294mm, wall thickness 2mm, structure wall thickness 16.5mm.Implementation process is as follows: material is extruded behind the supercooling diameter-setting equipment by extruder, becomes T bar plastic composite strip material, and the internal layer wall thickness is 2mm.Traction is adjusted internal mold angle of swing and speed to Wrapping formed machinery, utilizes the fusion rubber extruding machine to fill hot melt adhesive and cool off simultaneously, thereby forms continuous tubing, and fixed length cutting is also carried out reprocessing.This physical properties of articles is as shown in table 1:
Table 1
Sampling 1800SN8 pipeline, internal diameter of the pipeline 1785mm, wall thickness 6mm, structure wall thickness 79.54mm.Implementation process is as follows: material is extruded behind the supercooling diameter-setting equipment by extruder, becomes T bar plastic composite strip material, and the internal layer wall thickness is 6mm.Traction is adjusted internal mold angle of swing and speed to Wrapping formed machinery, utilizes the fusion rubber extruding machine to fill hot melt adhesive and cool off simultaneously, thereby forms continuous tubing, and fixed length cutting is also carried out reprocessing.This physical properties of articles is as shown in table 2:
