[0002] The steel cylinder concrete pipe used in the jacking construction method occupies a pivotal position in modern pipeline engineering. The uniqueness of this pipe is that it has a highly watertight steel cylinder embedded inside. This design gives it the characteristics of high strength, high impermeability and high durability. Because of these outstanding properties, steel cylinder concrete pipes are widely used in urban water supply, drainage engineering and water conservancy engineering, especially in those occasions where traditional excavation construction methods are difficult to implement or the cost is too high. Steel cylinder concrete pipes have shown great advantages through the jacking construction method.

[0003] When manufacturing this high-performance pipeline, the production process of the steel cylinder is a crucial link. At present, there are two main steel cylinder production processes in China: plate welding and automatic coil welding. Although automatic coil welding technology can achieve efficient and continuous production, the corresponding equipment investment is huge, and the cost of a set of semi-automatic coil welding machines is often too high. Moreover, this machine has a complex structure, and installation and maintenance require a professional technical team, which increases the cost of production and maintenance.

[0004] On the other hand, although the equipment cost of the plate welding process is relatively low, the unreasonable design of the welding platform often leads to unevenness (warping) and inaccurate dimensions of the welded plate. These problems not only affect the appearance quality of the steel cylinder, but more importantly, they have a direct impact on the sealing and durability of the steel cylinder, thereby reducing the overall performance of the steel cylinder concrete pipe. Therefore, optimizing the plate welding process and improving the flatness and dimensional accuracy of the welded plate have become the key to improving the quality of the steel cylinder concrete pipe.
