The spiral corrugated pipe with the structure of the utility model has firm and reliable connection after being connected, and the spiral corrugated pipe has convenient processing and high efficiency.
Description
Technical field
The utility model relates to steel band reinforced polyethylene spiral ripple pipe, particularly the steel band reinforced polyethylene spiral ripple pipe of medium-small diameter.
Background technique
Steel band reinforced polyethylene spiral ripple pipe has plurality of advantages such as inner wall smooth, critical external compressive resistance ability are strong, corrosion-resistant, is the desirable ground draining pipeline that buries.The helical corrugation body that traditional steel band reinforced polyethylene spiral ripple pipe is made of inner layer polyethylene, helical steel band and outer layer polyethylene, described helical steel band is located between inner layer polyethylene and the outer layer polyethylene.The helical bellows of this structure has two kinds of docking calculations when construction, the first is at first docked the port of two bellowss, utilize welding machine that port is welded together then, it two is with the butt joint of the port of two bellowss, then the hot melt band is wrapped in jointing, hot melt band secondary is heated connects.These two kinds of Placements, after the interface connection,, prevent that jointing from leaking in order to strengthen the join strength of interface, need the inwall of docking port to carry out repair welding, this process, for the big pipeline of diameter, operator can construct in pipeline very easily, and enter in the pipeline difficult for the pipe operations personnel of medium-small diameter, construction is inconvenient, and joint efficiency is low, project progress is slow, and connects low, the poor stability of reliability.
In order to overcome above-mentioned defective, other forms of steel band reinforced polyethylene spiral ripple pipe has appearred, at notice of authorization number is to be to disclose socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe in the patent document on June 25th, 2008 to comprise with outer layer polyethylene the metal frame that twines is fixed on the inner layer polyethylene 2007.9.25 notice of authorization day for the CN201078525Y applying date, one end of bellows is provided with socket, the other end is provided with bellmouth, imbed a circle electric heating element on the bellmouth inwall, the electric heating element both ends head stretches out the bellmouth inwall.Though this structure connecting part,, the inwall of bellmouth and the outer wall of socket are cylindrical, in socket is inserted into bellmouth after, if having intermittently, then be difficult to socket and bellmouth are fused to together, therefore, the poor reliability of connection; Electric heating element processing processes inconvenience on the inwall of bellmouth.
The model utility content
The purpose of this utility model is for a kind of steel band reinforced polyethylene spiral ripple pipe is provided, the utility model structure, helical bellows is connected firmly after connecting, reliably, helical bellows easy to process, efficient is high.
For achieving the above object, a kind of steel band reinforced polyethylene spiral ripple pipe comprises the helical corrugation body that is made of inner layer polyethylene, helical steel band and outer layer polyethylene, and described helical steel band is located between inner layer polyethylene and the outer layer polyethylene; One end of described helical corrugation body is provided with bellmouth, and the other end is provided with socket; The internal surface of described bellmouth is taper, and the outer surface of socket is taper, the tapering equal and opposite in direction of bellmouth internal surface and socket outer surface; Welding has the hot melt guipure that radially twines on the described socket outer surface.
Said structure, because the internal surface of bellmouth and the outer surface of socket are taper, and tapering equal and opposite in direction, after wherein the socket of a helical bellows is inserted into the bellmouth of another helical bellows, during insertion, gap between two helical bellowses can be more and more littler till closely contacting, on the hot melt guipure, switch on then to melt polyethylene, two helical bellowses are closely linked together, therefore, be connected firmly after helical bellows connects, reliably, and do not need the inwall interface is carried out repair welding, for construction has brought convenience; When being worked into the hot melt guipure on the socket, earlier the hot melt guipure is wrapped on the outer wall of socket, then, heating socket outer wall, simultaneously the hot melt guipure being exerted pressure is fused on the socket hot melt guipure, because the hot melt guipure is a banded structure, surface area is big, therefore, be not easy in the time of on being wound into socket to drop from socket, therefore, helical bellows easy to process, efficient is high, and, after giving the energising of hot melt guipure, the hot area of socket and bellmouth is even, and therefore, the quality of connection of two helical bellowses is good.
As improvement, described hot melt guipure is provided with two end part, and two end part are connected with electrode.The extraneous power supply of the convenient connection of electrode is set.

Fig. 2 is the sectional view of steel band reinforced polyethylene spiral ripple pipe;
Fig. 3 is the connection diagram of two steel band reinforced polyethylene spiral ripple pipes.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Steel band reinforced polyethylene spiral ripple pipe as shown in Figure 1, 2, comprise by the helical corrugation body 1 that constitutes by inner layer polyethylene, helical steel band and outer layer polyethylene that is arranged in order from inside to outside, one end of helical corrugation body 1 is connected with bellmouth 2, the other end is connected with socket 3, the internal surface of bellmouth 2 is taper, the outer surface of socket 3 is taper, the tapering equal and opposite in direction of bellmouth 2 internal surfaces and socket 3 outer surfaces; Welding has the hot melt guipure 4 that radially twines on the socket outer surface, and the hot melt guipure has two end part, is connected with electrode 5 on the two end part, is convenient to and extraneous electrical communication.
The process that the utility model helical bellows connects is: as shown in Figure 3, at first, the socket 3 of a helical bellows wherein is inserted into the bellmouth 2 of another helical bellows, and the outer surface of socket and the internal surface of bellmouth are closely contacted, switch on to hot melt guipure 4 by electrode 5 then, hot melt guipure 4 energising back heating makes the polyethylene of the internal surface of the outer surface of socket 3 and bellmouth 2 be in molten state, after a period of time, cut off to feed the power supply of hot melt guipure 4, make socket and bellmouth natural cooling and interconnect.This structure, because the internal surface of bellmouth 2 and the outer surface of socket 3 are taper, and tapering equal and opposite in direction, the socket of a helical bellows is inserted in the journey of bellmouth of another helical bellows therein, gap between two helical bellowses can be more and more littler till closely contacting, and therefore, is connected firmly after helical bellows that hot melt cools off then connects, reliably, and do not need the inwall interface is carried out repair welding, construction is got up convenient.
The process that hot melt guipure 4 is worked on the socket 3 is: earlier hot melt guipure 4 is wrapped on the outer wall of socket 3, then, heating socket 3 outer walls, simultaneously hot melt guipure 4 being exerted pressure is fused on the socket 3 the hot melt guipure, because the hot melt guipure is a banded structure, surface area is big, therefore, be not easy in the time of on being wound into socket to drop, therefore from socket, helical bellows easy to process, efficient is high, and after giving the energising of hot melt guipure, the hot area of socket and bellmouth is even, therefore, the quality of connection of two helical bellowses is good.
