The embodiment of the utility model provides a skeleton reinforcing winding arrangement wall tubular product, this structure wall tubular product carry out the spiral winding by strip 100 and form. The strip 100 comprises a hollow frame 110 inside and a cladding 120 on the outside, the overall shape of the cross-section being rectangular.

Because the overall cross section of the strip 100 is rectangular, the inner and outer walls of the structural wall pipe formed by spirally winding the strip side by side on the forming drum are smooth planes, and compared with a corrugated pipe with protrusions, the outer surface of the pipe is not easily damaged during transportation. In addition, the cylindrical smooth outer surface is easy to bury during construction, and the defect that soil on the pipe belly is difficult to fill is overcome. The strip material 100 comprises a plurality of hollow frameworks 110 as reinforcing frameworks, so that the overall rigidity of the winding structure wall pipe is improved, and the pipe can be used under a road surface with an overload load. Meanwhile, compared with a solid-wall pipe, the steel pipe has lighter weight per meter under the condition of the same ring stiffness, saves a large amount of materials and reduces the production cost.

The material of the coating layer 120 at the outermost layer of the strip 100 is High Density Polyethylene (HDPE), which is a non-polar thermoplastic resin with high crystallinity, has the characteristics of resistance to most of domestic and industrial chemicals, no moisture absorption, good water vapor resistance, excellent impact resistance and outstanding stress cracking resistance, and enables the structural wall pipe to have good flexibility and overall external pressure resistance. When earthquake, ground uneven settlement and other geological activities occur, the damage loss of the pipeline can be reduced to the minimum, and the earthquake resistance and disaster reduction capability of the public facilities are improved. Besides high density polyethylene, the material of the outer layer 120 may also be selected from Polyethylene (PE), polyvinyl chloride (PVC), etc.

It should be noted that the process of spirally winding the strip 100 side by side to form the tube with the reinforced winding structural wall includes: the preformed strip 100 is spirally wound on a continuously rotating forming roller side by side, so that the side walls of the adjacent strip 100 are in close contact, the side wall coating layers 120 of the adjacent strips are melted and then extruded and welded into a whole, and the framework reinforced winding structure wall pipe is formed after cooling and setting. Or, spirally winding the preformed strip material 100 side by side on a continuously rotating forming roller, wherein the adjacent strip materials 100 are close to each other but have certain gaps, extruding molten melting glue 200 into the gaps for bonding, and forming the framework reinforced winding structure wall pipe after cooling and shaping.

Wherein, strip 100 is certain inclination with the axis direction of structural wall tubular product and carries out side by side spiral winding, makes the structural wall tubular product structure that forms after the winding to have certain angle with the pressure-bearing direction (usually for level or vertical), slows down the pipeline pressurized condition to a certain extent. The outer surface of the combined hollow frameworks 110 is uniformly coated with the high-density polyethylene to form the winding strip 100, so that winding and rolling fusion times can be reduced during production, for example, structural wall tubes with the same length are produced, the winding times of the strips formed by combining the two frameworks are at least half of the winding times of the strips of the single framework, meanwhile, bonding materials between the adjacent strips 100 are reduced, the manufacturing process of the winding structural wall tubes is simplified, and the production efficiency is effectively improved.

According to some embodiments of the present invention, the strip material 100 is composed of an internally contained hollow skeleton 110 and an outer cladding 120. The hollow frame 110 may be a single polypropylene pipe, such as a polypropylene single-wall corrugated pipe, or may be a combination of a plurality of hollow frames 110. The hollow frameworks 110 may be hollow frameworks 110 having the same cross section, or irregular hollow frameworks 110 having different cross sections, and it is only necessary to ensure that the overall cross section is rectangular after the outer layer is coated with the coating layer 120. The hollow frames 110 may be closely contacted with each other and then coated with the coating layer 120 on the outer surface, or may be arranged at a certain distance, and the coating layer 120 is coated in the space and on the entire outer surface to form the strip 100 having a rectangular overall cross section.

It should be noted that the plurality of hollow frames 110 can be preformed tubes of various materials, such as rectangular polypropylene single-wall corrugated tubes, steel hollow frames or polyvinyl chloride hollow frames.

Specifically, referring to fig. 1 and 2, the plurality of hollow bobbins 110 may be two polypropylene rectangular hollow bobbins 110 having the same cross section. In fig. 1, two identical pre-formed rectangular pipes are closely contacted and then coated with high density polyethylene to form a strip 100. In fig. 2, two identical pre-formed rectangular tubes are spaced apart a distance, and a high density polyethylene coating 120 is applied over the spaced apart distance and over the outer surfaces of the two rectangular tubes.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
