1. This treatment scheme is mainly for large karst caves under the foundation and pavement, and the crossing treatment scheme is adopted. 2. This drawing is applicable to limestone sections or fault fracture zones where water inrush and gushing may occur. The judgment standard is that the flow of a single hole in the advanced exploratory hole is>2m/ h， Total water volume>10m/ h。 3. According to the past experience and lessons, when collapse and other accidents occur behind the tunnel face, the construction personnel are likely to be trapped in the tunnel; In order to ensure the safety of trapped personnel, implement rescue quickly and effectively, and minimize accident losses, relevant engineering measures and preparation of relevant rescue facilities and equipment shall be considered during tunnel construction. 4. This treatment plan is mainly for the sections with karst caves developed at depth less than 2.0m outside the tunnel excavation face (above the arch waist, under the foundation and pavement), and the karst caves developed at the side wall. In principle, backfilling is adopted for treatment. 5. This treatment scheme is mainly aimed at the treatment scheme that the development depth of karst cave outside the tunnel excavation face above the arch waist is more than 2.0m, and the width of karst cave is less than the tunnel excavation face. 6. This treatment scheme mainly aims at the treatment scheme for karst caves with a depth of more than 2.0m outside the tunnel excavation face above the arch waist, a width of less than that of the tunnel excavation face and a depth of more than 5.0m in the base, and a width of less than that of the tunnel excavation face. ...... Drawings include: karst treatment plan design drawing, tunnel emergency plan design drawing...... 6 sheets in total

Content introduction 1. Project overview Shiyan xx Tunnel is a single track tunnel with an entrance mileage of DzK114+338 and an exit mileage of DzK118+788, and a total length of 4016.83m (433.17m short chain). Niugou inclined shaft is set at DzK117+220, with a length of 232.22m, an included angle of 48 ° and a vertical angle of about 5 ° 59 ′ 41 ″. Most of the tunnel body is located on a curve, the inlet is located on a curve with a radius of 4000m, the tunnel body is an "S" curve, and the tunnel body and outlet section are located on a reverse curve with a radius of 2000m. The longitudinal slope of the line is a single slope of - 4.4 ‰, - 10.5 ‰ and - 5 ‰.
