通过对我国当前制管工具的调查分析,并参阅国外先进制管技术,上海隧道工程设计院开发了一种能在施工现场就地生产混凝土管节的新颖的移动式弹性钢模。该钢模拆装方便,组装成形后精度高。其内模结构采用计算机优化设计,机构动作配合巧妙,构思新颖,起吊脱模一次完成。接缝采用橡胶 Through the investigation and analysis of China’s current pipe-making tools, and referring to foreign advanced pipe-making technology, the Shanghai Tunnel Engineering Design Institute has developed a new type of movable elastic steel mold that can produce concrete pipe joints on-site at the construction site. The steel mold is easy to assemble and disassemble, and has high precision after being assembled and formed. The internal mold structure adopts computer optimization design, the mechanism moves with ingeniousness, the concept is novel, lifting and demoulding are completed once. Joints using rubber
