Research on Lining Construction Technology of Small Curved Radius Tunnel with Variable Cross-Section
Secondary lining construction is a crucial process in underground engineering construction,and lining trolleys are commonly used for construction.However,with the increase of underground engineering types,various types of lining structures have emerged,such as variable cross-section small curved radius tunnel lining.Traditional lining trolleys cannot meet the current construction needs,and special research is needed.This technical research mainly focuses on the height adjustment device and width adjustment device of the lining trolley,as well as the design of the curved section trolley.It has successfully solved a series of problems such as safety,quality,construction period,environmental protection,and cost of the lining of small curved radius tunnels with variable cross-sections.Through a large amount of engineering practice,it has been proven that the formed construction technology is becoming increasingly mature and perfect,which has a significant effect on ensuring the quality stability and control of the lining of small curved radius tunnels with variable cross-sections.It can provide reference and guidance for subsequent tunnel lining construction of the same type.
