全逆作建筑地下加速器机房混凝土施工技术
摘要
Abstract
The main problems in the concrete construction of the underground accelerator room of the whole top-down building are as follows:it is difficult to guarantee the strength of C40 concrete prepared with brittle barite;the segregation is caused by downward transportation of concrete,and there is difficulty of simultaneous pouring in large quantities in limited space;mass concrete is prone to temperature cracks.The following measures have been taken:the qualified radiation-proof concrete is prepared by carefully selecting the material;the pressure relief deviceis used to solve the downward conveying segregation,and multi-group construction to achieve generous pouring;temperature cracks are effectively controlled through internal cooling,external heat preservation and repeatedly temperature measurement.The technology meets the requirements of crack control,therefore the pouring quality proves good.关键词
