Analysis on Construction Technology of High-strength Radiation-proof Mass Concrete Shear Wall
In order to ensure the construction quality of high-strength radiation-proof shear wall,taking a proton irradiation project as an example,a formwork support scheme with no holes in the wall and four guarantees and a group layered concrete placement scheme were proposed.The results show that not cutting off the tension screw and directly cutting and sealing both ends can effectively ensure the radiation resistance of concrete;In concrete pouring,the material stiffness and overall integrity in the template support scheme of the four guarantee systems are high,which can avoid formwork expansion and reduce the risk of formwork explosion;Grouping and layering pouring effectively ensures the quality of concrete pouring.
