摘要
随着顶管技术在市政工程中的广泛应用,大直径预制砼管节的应用越来越普遍.大直径矩形顶管砼管节具有断面尺寸大、自重大、结构强度要求高、制作工艺复杂、质量精度及抗渗要求高等特点,因此采用科学合理的管节预制工艺尤其重要.
Abstract
With the extensive application of pipe jacking technology in municipal engineering,the application of large diameter prefabricated concrete pipe joint is more and more common.The large diameter rectangular pipe jacking concrete pipe joint has the characteristics of large section size,self-weight,high structural strength,complex manufacturing technology,high quality precision and high impermeability.Therefore,it is particularly important to adopt scientific and reasonable prefabrication technology.
