Description

An integrally formed reinforced structural wall pipe

technical field

The utility model relates to the technical field of plastic pipes, in particular to an integrally formed wall pipe with reinforced structure.

Background technique

Winding structural wall pipes belong to the field of chemical building materials. They are replacement products of plastics for steel and plastics for cement. They are widely used in municipal drainage, long-distance low-pressure water delivery, mine and chemical drainage, farmland water conservancy irrigation and ventilation pipes and chemical containers. It is of great significance to save energy, reduce pollution and protect the environment. At present, the winding structure wall pipes on the market are mainly all-plastic winding structure wall pipes. The all-plastic winding structure wall pipes have good low-temperature brittleness resistance and high welding performance. They have good toughness, a wide range of construction, and strong applicability. The service life can also reach 50 years. However, due to the fact that the existing all-plastic structural wall pipes usually include the pipe wall and the reinforcing ribs arranged helically along the outer surface of the pipe wall, the pipe wall is formed by hot extrusion and winding of high-density polyethylene or polypropylene material, and the reinforcing ribs include A polypropylene skeleton tube and a high-density polyethylene layer wrapped around the polypropylene skeleton tube. On the one hand, for pipes of this structure, in order to ensure equidistant winding of the outer layer of reinforcing ribs, the diameter of the inner layer of pipe should not be too large, otherwise the winding position of the outer layer of reinforcing ribs will be affected due to the deep corrugation formed on the surface of the pipe. It leads to irregular appearance of the product and directly affects the strength of the pipe. On the other hand, the main materials of pipes with this structure are high-density polyethylene and polypropylene, which have a single layer and are limited by the elastic modulus of the material. With the increase of the pipe diameter of the structural wall, the ring stiffness will decrease rapidly, resulting in The diameter should not be too large, which limits the application of the product.

In the current wall pipe with winding structure, the main pipe is usually wound first, and then the winding pipe is wound on the main pipe. This processing method has complicated procedures and low processing speed, which is not conducive to improving production efficiency.

For the winding wall pipe with a larger diameter, the current preparation process has certain difficulties in the manufacturing process.

detailed description

The technical scheme of the utility model is further described and illustrated through specific embodiments below.

Example:

An integrally formed wall pipe with reinforced structure, as shown in Figures 1 and 2, the pipe is formed by winding a winding tape 1, and the winding tape 1 includes a base material 2 and a reinforcing pipe 3 integrated with the base material 2, the base A hollow cavity 4 is provided inside the material 2, and the cross section of the hollow cavity 4 is a circle as shown in FIG. 1 , a chamfered rectangle, a semicircle or an ellipse as shown in FIG. 2 . The opening of the hollow cavity 4 can save unnecessary material waste. Setting the base material 2 and the reinforcing tube 3 as one body can save some steps in the manufacturing process of the structural wall tube, thereby simplifying the process.

Compatible crimping positions 5 are provided on both sides of the base material 2 , and the wrapping tape 1 is joined by the crimping positions 5 after being wound and molded and then thermoplastically connected.

As shown in Fig. 3, after improvement, both the base material 2 and the reinforcing tube 3 are provided with reinforcing ribs 6, and the reinforcing ribs 6 are integrated, and the reinforcing tube 3 is also a round tube, an elliptical tube, a semi-circular tube or a square tube. The outer wall of the reinforcing pipe 3 is provided with a reinforcing bar 7, and the reinforcing bar 7 is provided with a reinforcing rib 6, and the base material 2, the reinforcing tube 3 and the reinforcing rib 6 in the reinforcing bar 7 are integrated.

The reinforcing ribs 6 in the reinforcing bar 7 are positioned on both sides of the hollow cavity 4, and are in the shape of an arc with an opening obliquely upward.

The reinforcing ribs 6 are arranged in the reinforcing pipe, the base material 2 and the reinforcing strips, all of which are to ensure the ring stiffness after the diameter of the prepared structural wall pipe is increased. When the traditional preparation process is used to prepare large-diameter structural wall pipes, not only the process steps are complicated, but also the overall ring stiffness will often be reduced. The related solution is to thicken the pipe wall. This scheme is to thicken the pipe wall At the same time, on the premise of ensuring the ring stiffness, the amount of materials used should be reduced as much as possible, so as to save energy, reduce costs and improve competitiveness.
