Description
Technical field
The present invention relates to constructing tunnel field, the more particularly, to circumferentially continuous karst cave treatment side of karst landform tunnel beading
Method.
Background technology
The enforcement planned along with " one with a road ", southwest highway enters fast-developing period, southwest
Ground situation is typical Karst landforms, the globality poor of karst features, many solution cavities or contain mud, chamber containing Sha Rong, cranny development,
Interlayer is more, rock unrooted, only leans on the frictional force between rock to fix, easily occurs loosening block, the danger of fall.String
Pearl solution cavity is more dangerous with respect to the solution cavity of other forms and complicated, circumferentially continuous appearance in especially same mileage section
Solution cavity, country rock developmental state is unknown, secondary development easily, to the peace of the constructing tunnel of the solution cavity section construction of Karst Geological Landscape
Entirely, progress and benefit cause difficulty.
Especially vault occur solution cavity, need to carry out early stage closing again, thus the principle of vault karst cave treatment be in line with
Safety first, early closing, light and handy, high-strength, be easy to construct, conventional design is stuffed entirely with completing, or carries out formwork erection with concrete and beat
The mode of shield arch, time-consuming, laborious, effect is poor, is difficult to construct.
