[0090] Example
[0091] This construction method has been applied in the construction of No. 2 open-cut tunnel of Beijing-Xiong Intercity Railway Airport, effectively avoiding the quality defects of conventional tunnel lining concrete construction and improving the construction quality of lining. Compared with traditional concrete technology, each lining can save about 2h of time and save 2 workers.
[0092] The No. 2 tunnel of Beijing-Xiong Intercity Railway Airport is connected to the underground station of Beijing New Airport in the north, and is exposed to the ground after passing through the Yongding Henan embankment in the south. The starting and ending mileage is DK44+911.349~DK53+300, and the total length is 8338.651m. Among them, DK46+092~DK48+000 within the scope of this bid section is the unadjusted part of the line, which is 1908m long, and DK48+000~DK53+300 is the line adjustment part, with a total length of 7208m.
[0093] The area to which the line belongs is located ...
