针对传统的钢板桩、钢筋混凝土沉井、砖砌井、搅拌桩等支护存在的问题,开发了钢制沉井,并在市政工程中进行了多次使用,取得了良好效益。介绍了钢制沉井的制作工艺、施工操作要点及辅助措施等。实践表明,该施工技术易于控制质量、保证安全、加快进度,具有重复利用、适用性强、质量可靠、施工安全、不污染环境等优点。
Aiming at the problems existing in the traditional steel sheet pile, reinforced concrete caisson, brick well, mixing pile and other support problems, the steel caisson has been developed and used repeatedly in the municipal engineering, which has achieved good benefits. Describes the production process of steel caisson, construction operation and auxiliary measures. Practice shows that the construction technology is easy to control the quality, ensure safety, speed up the progress, with the advantages of reuse, adaptability, reliable quality, construction safety, do not pollute the environment.
