The application provides a special long highway
tunnel ventilation shaft vertical shaft method construction method, comprising the following steps: S1, measuring and
lofting; S2, shaft mouth section construction; S3, vertical shaft
lifting equipment installation; S4, shaft body construction; S5, equipment inspection, adjustment and next S4 until excavation and support are completed; S6,
middle line re-measurement, shaft bottom construction, shaft bottom leveling, layer lining and backfilling, and hoist platform modification; S7, measuring and
lofting, adjusting the hoist platform center to the vertical shaft design center, shaft inner anti-drainage layer construction,
steel bar binding, form erection, concrete pouring, finishing and maintenance, and second lining construction of the vertical shaft; S8, lifting the hoist platform, and next S7 until the second lining is completed; S9, dismounting the
lifting equipment. The application has strong applicability in project construction under poor geological conditions and strict construction period requirements; the construction period can be freely set, is not affected by the main
tunnel construction period, is more scientific and reasonable, the construction process is reasonably connected, and the construction quality is safe and reliable.
