| Abstract: | For slow construction and poor quality of the traditional construction method for invert, a rapid construction technology of invert in high-speed double tracks railway tunnel was developed through innovating the construction process and equipment. The application of the new technology in a tunnel construction of Guiguang Railway shows that the rapid construction technology can shorten the operating cycle time significantly, speed up the invert construction speed, and ensure the distance between invert and tunnel face; furthermore, the invert mold newly developed can effectively avoid the joint faulting and overrun during invert pouring, and the overall deviation and so on. |
