Abstract:
The length of Xianglushan tunnel is 62.596 km,which is the longest deep buried tunnel in the diversion project of central Yunnan Province.The whole section of the tunnel needs secondary lining,the amount of lining is large,and the construction strength is high.Limited by the terrain conditions,the inclined shaft was used as the construction passage in some construction branches.On the basis of summing up the concrete transportation schemes of inclined shafts in similar projects,according to the characteristics of inclined wells in Xianglushan tunnel and the transportation requirements of concrete construction,the schemes of transporting concrete by pumping,chute and hoist were proposed respectively,and the main technical measures adopted in the construction of each scheme were analyzed.Relevant experience can be used as reference for similar projects.
