Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the pipes used in home decoration have also experienced the development process of ordinary cast iron pipe → cement pipe → (reinforced concrete pipe, asbestos cement pipe) → ductile iron pipe, galvanized steel pipe → plastic pipe and aluminum-plastic composite pipe . PE corrugated pipe, a new type of lightweight pipe made of high-density polyethylene, has a smooth inner wall, trapezoidal or arc-shaped corrugated ribs on the outer wall, and a hollow pipe between the inner and outer corrugations. It has the characteristics of strong resistance to external pressure, low engineering cost, convenient construction, low temperature resistance and impact resistance, good chemical stability, and long service life. It is widely used in industrial and civil outdoor drainage systems and is an environmentally friendly green product. It has become the preferred pipe material for "replacing steel with plastic" in the pipeline field. It overcomes the shortcomings of cement pipes, ceramic pipes, and cast iron pipes, which are difficult to install, easy to rust, large water flow resistance, breeding bacteria, and short life.

Existing corrugated pipes have low compression resistance, and are easily deformed by other objects during use, resulting in damage to the corrugated pipes. The crack resistance is also weak, and they are easily cracked after deformation, making them unusable.

Utility model content

The purpose of this utility model is to provide a reinforced winding corrugated pipe with HDPE to solve the problem that the existing corrugated pipes proposed in the above background technology have low compressive performance and are easily deformed by other objects during use, causing corrugation.

In order to achieve the above purpose, the utility model provides the following technical solutions: a reinforced winding corrugated pipe with HDPE, including the outer pipe of the corrugated pipe, the raised ridge, the steel wire, the inner pipe of the corrugated pipe, the first rib, the metal braided layer and the second Two reinforcing ribs, the outer wall of the bellows outer tube is provided with a spiral raised ridge, the raised ridge is a hollow structure, and a steel wire is arranged in the hollow cavity, the connection between the bellows outer tube and the bellows inner tube A first reinforcing rib and a second reinforcing rib are arranged between them, and the inner wall of the outer tube of the corrugated tube and the inner tube of the corrugated tube are both provided with a metal braided layer.

Preferably, both the outer tube of the corrugated tube and the inner tube of the corrugated tube are made of HDPE.

Preferably, the steel wire has a helical structure, and the steel wire and the raised ridge spiral in the same direction.

Preferably, both the first reinforcing rib and the second reinforcing rib have a helical structure.

Preferably, the first reinforcing rib and the second reinforcing rib spiral in opposite directions.

Compared with the prior art, the beneficial effect of the utility model is that: between the outer pipe of the HDPE-reinforced winding corrugated pipe and the inner pipe of the corrugated pipe, the first reinforcing rib and the second reinforcing rib in the opposite direction are arranged, so that the corrugated The strength of the tube is greatly improved, and it has the function of energy absorption and buffering. When it is violently hit by an external force, it can absorb the impact force and reduce the probability of deformation and rupture of the bellows. And the raised ridge is provided with steel wires that spiral in the same direction , to enhance the pressure resistance of the bellows, the outer tube of the bellows and the inner wall of the inner tube of the bellows are equipped with a metal braided layer, which makes the bellows more flexible and can withstand a greater degree of deformation without damage, while increasing the bellows Excellent bending performance, better adapt to the surrounding environment. The corrugated pipe is made of HDPE, which is lighter in weight and higher in strength than other pipes. It is non-toxic, corrosion-resistant, non-scaling, recyclable, and can meet the needs of special environments. .
