Summary of Running and Operation of Aqueduct Building Machine for U- shaped Aqueduct with Large Span and Thin Wall

the operational technology on the aqueduct building machine( model: DZ40 /1600) for construction of the u- shaped aqueduct with large span and thin wall on the aqueduct over the Tuan River on the middle route of the south- to- north water diversion project is proved reasonable and simple through the site practice and continuous optimization of the machine,satisfying the engineering design requirements. The aqueduct body after being constructed and measured meets the design requirements in terms of structural sizes and construction quality. Therefore,application of this aqueduct building machine accumulates experience for the construction of the large aqueducts.
