Abstract
A reinforced and hollow spiral tube comprises a hollow tube and a pipeline wall, wherein the hollow tube is a spirally-wound tube; the pipeline wall is formed by fusion adhesive for adhering adjacent hollow tubes; the wall of the hollow tube adopts a double-layer structure; a plug port and a socket port are respectively fused at the two ends of the reinforced and hollow spiral tube; a circle of electrothermal elements are arranged on the outer wall of the plug port; the two ends of each electrothermal element are positioned at one end of a fusion part of the plug port and the reinforced and hollow spiral tube; and hot fusion is realized by electrifying the two exposed ends of the electrothermal element. The hollow tube provided by the utility model adopts the double-layer structure, and the outer edge angles of the tube wall are arc-shaped, so that the ring stiffness of a product is greatly improved; and the plug-socket electrofusion joint is adopted, so that the joint during a construction is quick, the operation is convenient, manpower and tools are saved, the joint quality is high, and leakage can be fundamentally eradicated.
Description
Technical field
The utility model relates to the tubing technology, particularly a kind of enhancing hollow wall entwining tube.
Background technique
Existing hollow wall winding pipeline is to extrude hollow square tube spiral on the Wrapping formed machine of heavy caliber with extruder to twine, and fills between adjacent hollow tube simultaneously that melten gel is bonding to process.Because of its hollow tube tube wall is a single layer structure, have following shortcoming: 1. consumption HDPE raw material is many, cost is high; 2. ring stiffness is low, and difficult quality is up to standard; 3. if reduce cost, the hollow tube raw material is through filling-modified melten gel and the bonding not firm phenomenon of hollow tube of then occurring, and there is serious hidden danger in quality of product.At present, the Placement used of existing hollow wall entwining tube has following several kinds: hot melt is extruded and is welded to connect, Electric thermal smelting belt connection, shrink belt connection, clip connected etc.The deficiency of these several kinds of Placements is the easy seepages of interface, poor reliability, and construction environment is required high.
Summary of the invention
The purpose of the utility model to provide exactly a kind of tube wall bulk strength high, be difficult for breaking, non-leakage, the high density polyethylene (HDPE) of good reliability strengthens the hollow wall entwining tube.
A kind of enhancing hollow wall entwining tube; Comprise the tube wall that the melten gel of hollow tube that spiral twines and bonding adjacent hollow tube forms; There are socket and bellmouth in said enhancing hollow wall entwining tube two ends welding respectively; Said socket outer wall is provided with a circle electric heating element, and the two ends of electric heating element is positioned at weld one end of socket and said tube wall, switches on through the two ends of the electric heating element that exposes and realizes hot melt; Said hollow tube tube wall is a double layer construction, and said hollow tube is embedded with the steel band with said hollow tube equal length.
Described hollow tube is a square tube, and the outer corner angle of tube wall are circular arc.
Said steel band cross section is circular or equilateral right angle corner type.
The cross section of described steel band has the adhesive layer of coating, outer layer plastic protective layer.
Said hollow tube skin is thinner, accounts for 10% one 30% of total thickness, and materials are less, and availability performance, quality higher H DPE raw material are processed, and both can reduce cost, and can guarantee the bonding fastness of melten gel and hollow tube again.
Compare with prior art, the advantage of the utility model is:
It is circular arc that the hollow tube of the utility model adopts double layer construction and the outer corner angle of tube wall, and the ring stiffness of product is improved greatly, connects quick during employing socket joint electric smelting jointing type joint makes and constructs; Easy to operate; Save manpower and facility, and quality of connection is high, can accomplishes that 100% does not have leakage.Owing to be embedded with the steel band with this hollow tube equal length, according to the physicochemical characteristics of plastics and steel band, according to the physical property of steel band different cross-sectional areas; Its intensity and rigidity improve greatly, are employed in the prefabricated spigot-and-socket joint of pipe end face welding, make thereby not only make the hollow wall entwining tube accomplish joint at manufacturing shop; And the advantage brought of spigot-and-socket joint, and since spigot-and-socket joint be welding at the pipe end face, not only the tube end face seal is good; Even outer wall is met external force, stress deformation like earth backing or after burying ground causes breakage; Also can not cause interior exosmosis, and joint can be isometrical with pipe, have made things convenient for pipe dragging in construction.In addition, end face welding spigot-and-socket joint, the joint welding is also easy than periphery welding bellmouth, good seal performance.

Fig. 2 is that the steel band of the utility model is circular structure;
Fig. 3 is the concrete structure of the utility model socket.
Embodiment
Like Fig. 1-2 illustrated embodiment, a kind of enhancing hollow wall entwining tube comprises the tube wall that the melten gel 1 of hollow tube 2 that spiral twines and bonding adjacent hollow tube forms.Described hollow tube 2 is a square tube, and the outer corner angle of hollow tube 2 tube walls are circular arc.
Said hollow tube 2 is embedded with the steel band 3 with said hollow tube equal length, and steel band 3 cross sections are circular or equilateral right angle corner type.The cross section of steel band 3 has the adhesive layer of coating, outer layer plastic protective layer.
As shown in Figure 3; Hollow wall entwining tube both ends of the surface welding respectively have isodiametric bellmouth 7 and socket 5; On socket 5 outer surfaces, be provided with electric heating element 4; Said electric heating element 4 is processed by the wire bending, and the two ends of electric heating element 4 is positioned at weld one end of socket 5 and hollow wall entwining tube, and switches on through the two ends of the electric heating element 4 that exposes and to realize hot melt; Adjacent two pipes insert through socket 5 and reach socket joint in the bellmouths 7 and connect, and realize hot melt through the two ends of the electric heating element 4 that exposes is switched on then.
Imbed a circle electric heating element 4 at socket 5 ends.Electric heating element 4 is that first wire with brake forming is fixed on socket 5 outer wall intermediate portions; Wire two ends termination 8 is protruding and fixing perpendicular to socket 5, gives the wire two ends 8 energisings then, energising voltage 40A; Keep 10 minutes current"on"time; Socket 5 outer walls are contacted with electric heating element 4 and around the position high density polyethylene (HDPE) melt, thereby imbed socket 5 outer walls with about half of electric heating element 4, wire two ends 8 is imbedded in the outer wall of socket 5 near the connection position of pipe shaft one end.
When site construction, the socket 5 with a high density polyethylene (HDPE) enhancing hollow wall entwining tube is inserted in the bellmouth 7 of another root hollow wall entwining tube; Then through switching on perpendicular to the outwardly directed electric heating element 4 of bellows; Energising voltage 54A keeps 20 minutes current"on"time, make contact with electric heating element 4 and around the high density polyethylene (HDPE) thawing of bellmouth 7 inwalls and socket 5 outer surfaces; Link together thereby two socket joint jointing type high density polyethylene (HDPE)s are strengthened the hollow wall entwining tube, become as a whole.Socket joint through high density polyethylene (HDPE) being strengthened hollow wall entwining tube docking operation successively repeatedly so just can connect into long and pipeline that good seal performance is arranged.
