1、Industry economic scale and technical level

Characteristics of industry scale:

China is the country with the largest production and application of cement concrete pipe and box culvert in the world. In the past 30 years, the industry has developed well as the industry scale, product specifications, technological innovation and equipment level have gradually started to move towards the world's advanced ranks.

Technological level:

At present, the main molding processes of reinforced concrete sewer pipes in China include: core mold vibration molding process, vertical radial extrusion pressing molding process, vertical vibration molding process, centrifugal casting process, suspension roller molding process and so on. Core mold vibration and radial extrusion pressing molding process are the main pipe-making molding processes.

2、Technical level of drainage pipe forming equipment

Core mold vibration pipe making equipment:

2020 is the 15th anniversary of the popularization and application of core mold vibration pipe making equipment independently developed in China, which has many advantages such as high production efficiency, safety, energy saving and good product quality, and is the preferred process for large and medium diameter pipes.

Radial extrusion pressing pipe equipment:

The domestic radial extrusion pressing pipe machine can be used for double-layer reinforced skeleton frame with a maximum diameter of 1650mm. The radial extrusion pressing pipe machine is popularized rapidly in small pipe production. No matter the maximum specifications produced by equipment, the speed of pipe production and the appearance and quality of pipe products are close to the foreign advanced level. Compared with the imported equipment, the required funds are greatly reduced, thus ending the plight of depending on imported radial extrusion pressing pipe equipment from abroad and starting to export to foreign countries.

Automatic production line of lifting core mold vibration

"Automatic production line of lifting core mold vibration pipe-making machine”, a lifting core mold vibration pipe-making forming equipment which integrates the advantages of radial extrusion and core mold vibration is innovated and developed by our country. Configured whole process and full-automatic operation system, it has the functions of operation data collection, precipitation, analysis and intelligent judgment and execution and is the highest automation production line of reinforced concrete sewer pipes in China at present.

Equipment for making reinforcement cage:

Φ4400mm reinforcement cage roll welder       NC steel fabric welder

The success development of NC steel fabric welding production line and vertical steel mesh bending machine improved the automation technology level and production efficiency of manufacture of reinforcement cage of precast concrete box culvert and saved human resources.

Innovative technology of box culvert mold

Box culvert mold is the key of precast concrete box culvert. In China, we have developed vertical steel mold and horizontal steel mold; single-bin mold and multi-bin mold; integral mold and assembling mold, realizing the standardization of box culvert mold.

3、Development direction of industry technology

Factory design of new double-layer sewer pipe production line

              Large diameter reinforced concrete sewer pipe will have a larger application space

Large diameter and high performance reinforced concrete sewer pipe can be used in development direction of key products like power tunnel project, sewage treatment project, water environment improvement project, urban underground pipe gallery project, urban underground water storage project and urban deep tunnel project.

Under the condition of corrosion resistance, all kinds of reinforced concrete composite pipes enjoy good market prospects
