Abstract
The utility model discloses a double-walled screwy corrugated casing tube which aims to provide a sheath tube having the advantages of high rigidity, high material utilization and low cost. The utility model comprises a light tube, wherein the outer surface of the light tube is provided with screwy reinforcing ribs spaced axially, the middle parts of the reinforcing ribs are hollow and the screwy reinforcing ribs and the light tube are made into a whole. The utility model has the advantages of simple structure, corrosion resistance, high temperature resistance, insulating property, easy fabrication and low cost. The double-walled screwy corrugated casing tube can be used as the sheath tube out of electric wires, cables, optical cables and other lines which are buried underground.
Description
Technical field
The utility model belongs to a kind of protective casing, more specifically to the protecting pipe of the buried usefulness of electric wire.
Background technology
In order to improve environment, to improve fail safe, electric power, Office of the Telecommunications Authority often circuits such as electric wire, cable, optical cable outside put corrosion-resistant, have the sleeve pipe of insulating properties, critical external compressive resistance power to be embedded in underground again.At present, sleeve pipe commonly used has the smooth light pipe of surfaces externally and internally, also has inner surface smooth, the bellows that outer surface is in wave shape, but these ripples all are solid, high material consumption, cost height.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of good rigidly, stock utilization height, double-walled helical fissure sleeve pipe that cost is low are provided.
In order to solve the problems of the technologies described above, the utility model is achieved in that and comprises light pipe, is shaped on the spirality reinforcement of axially spaced-apart at the outer surface of light pipe, and is hollow in the middle of the reinforcement, and spirality reinforcement and light pipe are made one.Used material can be a chliorinated polyvinyl chloride.
Double-walled helical fissure sleeve pipe according to the such scheme manufacturing, has bigger module of anti-bending section with comparing with the solid corrugated bushing of same material, good rigidly, and simple in structure, corrosion-resistant, high temperature resistant, have insulating properties, make the advantage simple, that cost is low.
Description of drawings
Figure is the half sectional view of double-walled helical fissure sleeve pipe.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Figure is the structural representation of double-walled helical fissure sleeve pipe.Its inside is circular light pipe 1, is shaped on the spirality reinforcement 2 of axially spaced-apart at the outer surface of light pipe 1, and is hollow in the middle of the spirality reinforcement 2, and its cross sectional shape is the hollow pipe of semicircle and rectangle combination, and spirality reinforcement 2 is made one with light pipe 1.Its material is made with chliorinated polyvinyl chloride.The cross sectional shape of reinforcement 2 can also be the hollow pipe of circle, square, trapezoidal, semicircle, semicircle and trapezoidal combination etc.
Claims (3)
1, a kind of double-walled helical fissure sleeve pipe comprises light pipe, is shaped on the spirality reinforcement of axially spaced-apart at the outer surface of light pipe, it is characterized in that in the middle of the described reinforcement be hollow, and spirality reinforcement and light pipe are made one.
2, double-walled helical fissure sleeve pipe according to claim 1, the cross sectional shape that it is characterized in that reinforcement are circle or rectangle or hollow pipe trapezoidal or semicircle or semicircle and rectangle combination or semicircle and trapezoidal combination.
