The development and progress of pipe culvert production technology in my country has greatly improved the output, quality, variety and specifications of pipes. Now all the tube making processes in the world, such as centrifugal forming process, suspended roller forming process, mandrel vibration forming process, radial extrusion forming process, vertical vibration forming process, etc.,Our country already has all of them and has achieved localization, and has reached the world's advanced level, and the technical content of the equipment is still improving.
Driven by national policies such as "supply-side structural reform drives innovative development of the industry", "Made in China 2025" leads industry development" and "urban infrastructure construction provides new development space for the industry", the development situation of the cement concrete pipe culvert industry is generally good, and the industry scale, product specifications, technological innovation and equipment level have made great strides towards the world's advanced level.
Level of process technology: The maximum specification for the manufacturing and application of my country's reinforced concrete drainage pipe products is Φ4400mm. Φ4000mm large-diameter reinforced concrete pipes and rectangular box culverts over 7m have been widely used in comprehensive pipe corridors, power tunnels and subway passages across the country; with the intensification of national low-carbon environmental protection requirements and the rise of labor costs, the core mold vibration forming process and radial extrusion forming process have become the main process technologies. Leading the production process; in addition to ordinary reinforced concrete pipe culverts, product types also include composite pipes lined with various materials, which are required for anti-corrosion and pollution control; various special-shaped pipes (oval, multi-arc base pipes) and extended prefabricated component products (prefabricated reinforced concrete inspection wells, prefabricated reinforced concrete septic tanks, ecological slope protection bricks, ecological permeable bricks, prefabricated cable trenches, prefabricated walls) are constantly designed and developed; jacking construction technology is being widely used in projects.
Guangzhou pipe corridor completed
Our country has the world's most complete main product series of pipe culverts.
Product type:
In addition to ordinary concrete circular pipes, there are also various special-shaped pipes and rectangular pipes (box culverts); Product structure: In addition to ordinary reinforced concrete pipe culverts, there are also composite pipes lined with various materials; Interface forms: flexible interfaces with rubber ring connections and rigid interfaces without rubber ring connections. At present, flexible interfaces have basically replaced rigid interfaces. Extended prefabricated component products: prefabricated reinforced concrete inspection wells, prefabricated reinforced concrete septic tanks, ecological slope protection bricks, ecological permeable bricks, prefabricated cable trenches, prefabricated walls and other components.
Radial extrusion process drainage pipe
Equipment technical level:
The technical level of my country's drainage pipe forming equipment has developed rapidly during the "Thirteenth Five-Year Plan" period, becoming the country with the ability to manufacture various advanced pipe and culvert equipment in the world, and realizing the localization of all advanced equipment. Domestic equipment is not only used domestically, but also begins to be exported abroad.
Core mold vibration pipe making machine
With the strengthening of national energy conservation and environmental protection policies, cement concrete pipe culverts are gradually forming a production pattern dominated by mandrel vibration technology and vertical radial extrusion technology, thus promoting the continuous improvement and improvement of the technical performance of mandrel vibration pipe making equipment and radial extrusion pipe making equipment. For example, the development of the rising core type mandrel vibration pipe making machine is the technological upgrade and technological innovation of mandrel vibration pipe making equipment. The development and application of CNC steel mesh welding production lines and the successful development of vertical steel mesh bending machines have further improved the automation technology level and production efficiency of pipe culvert production. Compared with the original traditional centrifugal process and hanging roller process, these process equipment are more mechanized and automated, with lower labor intensity and higher production efficiency. However, compared with similar foreign equipment, there is still a certain gap in terms of material performance, automation level, especially precise operation and strict management. To truly realize "exploitation of process characteristics + technological progress of equipment + rational application = perfection", the joint efforts of the entire industry are needed.
