Abstract
The utility model discloses a kind of novel double-wall bellows, belong to tubing technical field, including hollow wall, spiral shape outer wall and reinforcement, the spiral shape outer wall is made up of at least two helical corrugations, the top of the helical corrugation is internally provided with the first wire with the helical corrugation same-handed structure, and the second wire with the first wire opposite helical structure is provided with the hollow wall.The utility model double-wall corrugated pipe, rigidity, toughness and shock resistance are high, integral extrusion molding, and processing and manufacturing cost is low.
Description
Technical field
It the utility model is related to a kind of tubing technical field, more particularly to a kind of double-wall corrugated pipe.
Background technology
In recent years, the fast development in China city so that urban construction scale constantly expands, to city important infrastructure
Drainage and exhaust system requirement also more and more higher, double-wall corrugated pipe because its have ring rigidly it is high, in light weight, corrosion-resistant, be easy to
The advantages that installation, municipal drainage drainage project is used in more and more.Relatively badly, often occur in some geographical conditions
The place of situations such as soil settlement, pipeline need embedded deep, and this requires double-wall corrugated pipe to have enough rigidity and tough
Property come resist soil application power.But the ring stiffness of double-wall corrugated pipe in the market can not mostly meet that this use will
Ask.Some manufacturers are bonded outside double-wall corrugated pipe again by pasting enhancing structure in the hollow wall outer wall of advance extrusion molding
Layer, though this double-wall corrugated pipe improves ring stiffness to a certain extent, bonding part be present because of external force or internal stress itself
Act on scissile shortcoming.
Utility model content
To solve the problems, such as that prior art is present, the utility model proposes a kind of novel double-wall bellows of high ring rigidity.
The utility model is to solve the problems, such as that prior art has used technical scheme and is：A kind of novel double-wall ripple
Pipe, including hollow wall, spiral shape outer wall and reinforcement, the spiral shape outer wall is made up of at least two helical corrugations, described
The top of helical corrugation is internally provided with the first wire with the helical corrugation same-handed structure, on the hollow wall
It is provided with the second wire with the first wire opposite helical structure.
Preferably, the reinforcement is set for V-shaped, and the cavity that hollow wall is formed with spiral outer wall uniformly divides
For three equal parts.
Preferably, the hollow wall, spiral outer wall, reinforcement, the first wire and the second wire are integrally extruded into
Type.
Preferably, the spiral shape outer wall is in left or right rotation structure.
Preferably, the hollow wall, spiral shape outer wall and reinforcement are made up of PVC, PE or PP material.
The beneficial effects of the utility model：
（1）Double-wall corrugated pipe of the present utility model, contain second respectively in the top on hollow wall and helical corrugation
Wire and the first wire, the rigidity of double-wall corrugated pipe is improved from part and all on the whole；Even if simultaneously spiral outer wall by
Compressive strain is even crushed, the first metal in the second wire of hollow wall and the spiral outer wall of the opposite to that hand of spiral
Silk forms network structure, has so ensured the rigid nature of double-wall corrugated pipe；The wire of double-wall corrugated pipe inside and outside wall is to double
The rigidity of wall bellows provides double shield.
（2）Double-wall corrugated pipe of the present utility model, by adding in helical corrugation with increase V-type in the space of inwall formation
Strengthening tendons structure, further increase the rigidity of double-wall corrugated pipe.
（3）Double-wall corrugated pipe of the present utility model, its hollow wall, spiral outer wall, reinforcement and wire are integrated crowded
Go out shaping, without " shaping of open mold crawler type ", reduce processing cost, and close, excellent combination property is bonded inside and outside tubing.
Brief description of the drawings

The hollow wall 1, spiral shape outer wall 2 and reinforcement 3 are made up of PVC, PE or PP material.
The beneficial effects of the utility model：
（1）Double-wall corrugated pipe of the present utility model, contain second respectively in the top on hollow wall and helical corrugation
Wire and the first wire, the rigidity of double-wall corrugated pipe is improved from part and all on the whole；Even if simultaneously spiral outer wall by
Compressive strain is even crushed, the first metal in the second wire of hollow wall and the spiral outer wall of the opposite to that hand of spiral
Silk forms network structure, has so ensured the rigid nature of double-wall corrugated pipe；The wire of double-wall corrugated pipe inside and outside wall is to double
The rigidity of wall bellows provides double shield.
（2）Double-wall corrugated pipe of the present utility model, by adding in helical corrugation with increase V-type in the space of inwall formation
Strengthening tendons structure, further increase the rigidity of double-wall corrugated pipe.
（3）Double-wall corrugated pipe of the present utility model, its hollow wall, spiral outer wall, reinforcement and wire are integrated crowded
Go out shaping, without " shaping of open mold crawler type ", reduce processing cost, and close, excellent combination property is bonded inside and outside tubing.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model,
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
