Abstract
The utility model relates to a plastic double-wall winding pipe which is formed by winding and welding a plastic pipe with plastic hot melt glue. The radial section surface structure of the winding pipe contains a middle plastic pipe layer, a hot melt glue ektexine layer and a hot melt glue wall layer, and the axial section surface structure of the winding pipe comprises a plurality of plastic pipes, a middle layer which consists of hot melt glue connecting layers which are connected between the adjacent plastic pipes, a hot melt glue ektexine layer which is wrapped on the outside of the middle layer as well as a hot melt glue wall layer which is wrapped on the inside of the middle layer. Wherein, the plastic pipes are hollow circular angle squareness plastic pipes. The utility model, on the condition of the same ring rigidity, can save a plurality of materials while compared with the solid wall pipes and also has the advantages of light weight and therefore convenient transportation and installation, as well as good tenacity, plasticity and shockproof, smoothness of the inner walls of the pipes and fine water tightness. The utility model can be applied in city planning, industries, civilian uses, the drain and dirt eliminating projects of the civil constructions as well as in the long distance water transmitting as well as the agricultural flooding and other fields.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of plastic double-wall entwining tube.
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 concrete pipe, concrete reinforced pipe and cast iron tube, plastic tube have light weight, corrosion-resistant, the low pollution or free of contamination remarkable advantage, and plastic tube is also longer working life under identical withstand voltage condition.What plastic tube was relatively more commonly used at present is the pvc pipe material, though price is lower, it is heavier to exist quality, and withstand voltage deficiency has shortcomings such as a small amount of pollution.And the HDPE solid wall pipe, though function admirable, cost is higher, waste material.
The model utility content
The purpose of this utility model provides a kind of plastic double-wall entwining tube with new structure for the problems referred to above that overcome the prior art existence exactly.
The purpose of this utility model is achieved in that a kind of plastic double-wall entwining tube, and through twining and being welded with the plastic hot melten gel, the radially cross-sectional configuration of described entwining tube comprises middle part plastic pipe layer, hot melt adhesive outer wall layer and hot melt adhesive inner wall layer by plastic tube; The axial cross-sectional configuration of described entwining tube comprises by a plurality of plastic tubes and is connected the mesosphere that the hot melt adhesive tie layer between each adjacent plastic tube is formed, and the hot melt adhesive outer wall layer and the hot melt adhesive inner wall layer that is coated on the inboard, mesosphere that are coated on the outside, mesosphere.
Described plastic tube is a hollow rounded square plastic tube.
Described plastic tube is a hollow fillet square plastic pipe.
The utility model makes it compared with prior art owing to adopted above technological scheme, has following advantage and characteristics:
1, tube wall is the I-shaped structural walls, 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 radial cross section structural representation of Fig. 1 the utility model plastic double-wall entwining tube;
Fig. 2 is the axial cross section structural representation of the utility model plastic double-wall entwining tube;
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, Fig. 3, plastic double-wall entwining tube of the present utility model is welded through winding and with the plastic hot melten gel by plastic tube.Plastic tube wherein is a hollow rounded square plastic tube, preferably hollow fillet square plastic pipe.
Referring to Fig. 1, the radially cross-sectional configuration of the utility model plastic double-wall entwining tube comprises middle part plastic pipe layer 11, hot melt adhesive outer wall layer 21 and hot melt adhesive inner wall layer 22.
Referring to Fig. 2, cooperation is referring to Fig. 3, the axial cross-sectional configuration of the utility model plastic double-wall entwining tube comprises by a plurality of plastic tubes 1 and is connected the mesosphere that the hot melt adhesive tie layer 2 between each adjacent plastic tube is formed, and the hot melt adhesive outer wall layer 21 and the hot melt adhesive inner wall layer 22 that is coated on the inboard, mesosphere that are coated on the outside, mesosphere.
Hollow rounded square plastic tube in the utility model is that base stock is made with polyethylene or polypropylene or high density polyethylene (HDPE).
The utility model plastic double-wall entwining tube is when making, and material is extruded by extruder, behind the supercooling diameter-setting equipment, becomes hollow rounded square plastic tube.This hollow rounded square plastic tube is drawn to Wrapping formed machinery, adjust internal mold angle of swing and speed, fill the hot melt adhesive welding and cool off while twining by the hot melt adhesive extruder, thereby form continuous tubing, fixed length cutting is also carried out reprocessing and is promptly obtained finished product tubing.The structure wall thickness of tubing 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.
The plastic tube that adopts in the utility model plastic double-wall entwining tube is the fillet square tube, and this structure can make the tube wall junction fill more melten gel and more firm, and has solved the spiral leakage problems to a certain extent.
The pipeline structure of the utility model plastic double-wall entwining tube is to the helix structure that is tilt fixing, because of several angle being arranged with pressure-bearing direction (being generally level or vertical), slowed down pressure to a certain extent, compared, be not prone to whole section obscission with the straight burr pipeline of directly extruding.
