Abstract

Abstract: In order to solve the technical problem of spherical coupling construction for bottom swivel, improve the construction quality of bearing platform and accumulate the experience of spherical coupling construction, the construction scheme and key technology were studied by taking the construction of rotary rider cap across existing Changshen Highway in the new Tongliao-Xinmin north passenger dedicated line as an example. "Two-step method" construction process of spherical coupling and the sealing method of fast and effective were proposed, and the spherical coupling compactness and construction quality were guaranteed. The results of engineering practice show that spherical coupling construction scheme about "C60 self-compacting concrete +spherical coupling 'two-step' construction + grouting filling" is feasible, and the application effect is good.
