The method of constructing lining concrete in full scale underground storage

摘要

The invention of a large underground concrete lining and the Temple of Heaven Part bench (bench) excavation of Heaven section at the bottom parallel construction, improve the workability and the quality of the concrete lining by performing a lining concrete construction of the entire bench after the rest of the bench drilling, the present invention relates to a construction method of lining concrete in large underground cavity which can reduce the cost of construction and the air. The present invention is the first step in setting up the concrete lining of Heaven Part vibration limits according to the excavation of the bench 1 (Bench 1) of the excavation and reinforcement made after the massive underground portion of Heaven (Top Heading or Gallery) in a large underground caverns; A second step for calculating the optimum distance of the excavation and the concrete lining; Part of Heaven (Top Heading, Gallery) as the third stage separation distance calculated with the lining masonry construction parallel to one at the bottom of the excavation of the bench away from the end portion of Heaven; And the bench 1, a bench on the bottom 2 (Bench 2) or bench 3 (Bench 3) of the lining concrete construction method in a large underground cavity comprising a fourth step of pouring a concrete lining for an entire bench (Bench) after digging provided. ;
