Description

Technical Field

[0001] The present application relates to the technical field of corrugated pipe production, and in particular to a production device for corrugated pipes reinforced with steel strips in a side-by-side bundling system. Background Art

[0002] Steel belt reinforced polyethylene (PE) spiral corrugated pipe is a pipe structure with a corrugated structure made by compounding steel belt and PE. With high-density polyethylene (PE) as the matrix, the wavy structure formed by high steel belt coated with adhesive resin on the surface is used as the main supporting component, and the polyethylene composite material is interwoven with each other, and the steel belts are welded and connected through PE to form a complete double-wall spiral corrugated pipe. This pipe has the ultra-high rigidity and high strength of ordinary steel, and also has the flexibility, corrosion resistance and wear resistance of polyethylene composite materials. Due to its advanced material, simple implementation method, high construction efficiency, and material cost saving, it is widely used in municipal drainage pipe networks.

[0003] When the drainage network is used, it is necessary to connect the corrugated pipe to the other end of the pipe, the corrugated pipe to the inspection well, and the wellbore pipe to the well seat. The commonly used connection methods for these parts are: socket connection, welding connection and heat shrink tape connection, but the existing connection structure is simple, the installation part is weak, and there is a high risk of failure.

[0004] The existing connection methods are subject to the constraints of the construction environment. It is difficult to obtain a clean construction environment. It is impossible to ensure that the joint parts after the pollutants have been removed are clean before construction. The contaminated joints are used for subsequent connection construction, which will lead to a decrease in the reliability of the connection at the joint. The existing heat-shrinkable protective sleeves are all made of plastic, which easily react with the PE surface when heated, resulting in damage to the pipe surface when the protective sleeve is removed, increasing the risk of corrosion. When the local connection position of the underground pipeline fails, it will cause sewage and groundwater leakage, pollute the soil, and waste water resources.

[0005] At the same time, the existing corrugated pipes are also used in road drainage pipes. As pointed out in "[1] Dong Hanlin. Research on the mechanical properties of polyethylene spiral corrugated pipe culverts reinforced with soil-covered steel belts [D]. Beijing Jiaotong University, 2022. DOI: 10.26944 / d.cnki.gbfju.2022.001756.", under the same deformation rate, the corrugated pipes set up in a side-by-side bundling system have the highest arch soil bearing capacity. However, to obtain this structure, three steel belt-reinforced PE corrugated pipes must be arranged side by side on the construction site, and a polyethylene steel wire mesh pipe with a diameter of 125 mm must be filled in the gap between adjacent corrugated pipes. The pipes are wrapped and bundled with geotextiles and geogrids laid on their outer walls. This makes operation difficult and construction difficult in a construction environment. At the same time, it is easy for the interface of the structure to be adhered to by environmental pollutants, reducing the reliability of the interface connection and increasing the risk of leakage at the interface after construction.

[0006] The information disclosed in the background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

After the counterweight 135 is arranged, when the extended end of the geotextile 131 and the geogrid 132 is overlapped, the operator drives the hanging belt 134 to move in a directional manner by throwing the counterweight 135, thereby driving the extended end of the geotextile 131 and the geogrid 132 to move in a directional manner.
