中国散裂中子源密封筒高精度群锚预埋施工技术

High Precision Group Anchor Embedding Construction Technology of China Spallation Neutron Source Sealing Cylinder

中国散裂中子源(CSNS)项目技术难度高,涉及高精度和防辐射等综合技术,是我国首个散裂中子源项目,没有可借鉴的工程建设案例。项目重点包括靶站高精度施工控制技术、废束站高精度施工控制技术、质子加速隧道高精度施工控制技术、超大型热室不锈钢壳体高精度施工控制技术,以及盖板、基底、永久准直桩高精度施工控制技术。研究课题作为靶站高精度施工控制技术研究专题的一部分,重点研究散裂中子源靶站密封筒高精度群锚预埋的施工技术。

China Spallation Neutron Source(CSNS) project is difficult in technology,involving high precision and radiation protection technology. It is the first project of China's Spallation Neutron Source,and there are no engineering construction cases for reference. The project focuses on high-precision construction control technology of target station,waste beam station,proton accelerated tunnel,super-large heat chamber stainless steel shell, and cover,base and permanent collimation pile. As a part of the research project on high precision construction control technology of target station,this research focuses on the embedded construction technology of high precision group anchors for the sealing cylinder of target station of spallation neutron source.
