Standardized Construction Technology for Cable Trenches and Water Ditches in Large-span Separated Tunnel
In the construction of highway tunnels,the conventional construction of water ditches and cable troughs often uses small templates assembled and poured in stages.Due to the large number of templates and connecting joints,some construction defects may occur,resulting in poor overall integrity,poor surface flatness,and uneven linearity of the formed concrete.By analyzing and discussing the template structure,this article proposes a holistic mobile mold frame system.It solves the problems of multiple construction processes and a large amount of formwork support materials,controls and improves the impact of cross construction safety in small spaces,accelerates construction progress,effectively controls costs,ensures construction quality,and reduces operation time.
