Analysis on the Assembly Process for the Internal Arc Components of Large-Section Shield Tunneling and Key Quality Control Points for the Filling Layer
摘要
Abstract
This paper briefly introduces the current status and development of the assembly process for the internal structure of large-section shield tunneling.Based on engineering cases,the assembly process for the arc components of large-section shield and the key quality control points for the filling layer are analyzed,and a filling rate calculation method is developed.The filling quality is controlled from two aspects of the expansion degree of self-compacting concrete and the filling rate to ensure the compactness and fullness of the filling.This method can be used as a reference for the application of large-section shield arc component assembly process in similar projects.关键词
