| Abstract: | The roof structure of Tianjin West Railway Station is large-span grid shell structures which composed of spatial changing box-shaped members.The construction is difficult because of large-span and heavy weight.Based on the project practice,the division and multi-step lifting method with heavy lifting equipment is adopted.The triangle supporting tower is made of tube to shorten the construction period effectively.The high altitude accurate closure is completed by active control lifting technology,the control... |
