摘要
本文分析了双层钢筋混凝土井壁存在的问题,提出了充分利用外层井壁强度减小内壁厚度的设想,并提出了提高井壁混凝土标号,加锚固钢筋等使井壁减薄的措施。
this paper discusses the problems within double reinforced concrete shaftlinings and proposes making a good use of strength of outer lining of shifts so as to reduce the thickness of its interior lining. It also presents the methods for raising concrcte grade and putting some anchor reinforcing bars into reinforced concrete shaftlinings fo reduce the thickness, of the whole shaftlining
