Construction Technology and Application of Lining for Small Radius Long-distance Underwater Tunnel
Nuclear power plants typically use seawater for unit cooling.With the increasing environmental requirements,cooling water from nuclear power plants is discharged into the open sea through underwater tunnels,which need to be lined.The construction of long-distance underwater tunnels has high requirements for construction organization.Tunnel lining construction is carried out through the use of inverted arch formwork technology,side and top arch trolleys,and irregular formwork,and the horizontal transportation of concrete is carried out using track type concrete transport vehicles.It can ensure that the various technical parameters of concrete meet the requirements of the specifications,solve the problem of poor quality of concrete pouring in special positions,and improve the overall construction quality and efficiency.
