Description
Technical field
The utility model is related to highway subgrade water-proof drainage technical field, and more specifically, the utility model is related to one kind
Duo Xue areas road crossing avalanche slide rock body subgrade drainage system.
Background technology
With the development of transportation business, the mountain area that the increasing highway of China is avenged the severe cold more is built.Work as highway
When passing through large-scale avalanche slide rock body, can run into existing highway subgrade drainage system can not meet large-scale avalanche slide rock body area
Drainage requirement.Avalanche slide rock body area slope quality is soft, if bottom of slope generation rainwater soaks meeting when having rainfall, snowfall snow melt
Avalanche is caused, the stability of roadbed and the transportation function of highway communication is seriously threatened.High and cold mountain area is ecological weak, with rainy season or
The characteristics of person's snow melt season side slope flow rate of water flow is big, erosion is serious, the highway embankment stabilization to building causes great threat.
Winter severe cold period, if rainwater can not emptying rapidly, there is frost heave, serious destruction road under severe cold effect in the rainwater of residual
Base side slope and retaining wall structure.
Traditional highway subgrade water discharge method is to set an open drain along line alignment, and open drain is collected domatic
With the water that attacks of roadbed side slope excretion again by spaced transverse drain ditch arrange in a row it is middle discharge roadbed side slope beyond.This road
The discharge structure of base only considers from the project profile of common low altitude area, is not particularly suited for the large-scale avalanche slide rock avenged severe cold more
Body area.When many snow mountain areas of severe cold run into the seasons such as rainy season, snowfall, snow melt, it may occur that the current of big flow high flow rate collect
Leave from slide rock body surface face.Traditional gravity retaining wall protection side slope, its drainage pattern is to set drainpipe in wall bottom,
Drainage effect can not meet precipitate big flow high flow rate current.If can not discharge rapidly, rainwater can be long-pending behind in wall
Store, continuous lifting water level increases the stabilization that hydrostatic pressure threatens retaining wall, and in bottom of slope aggregation, soaks bottom of slope, it is likely that another
Secondary generation avalanche.When heavy showers occurs, more current can be collected at slide rock body, the design drainability of open drain is often
The drainage requirement at slide rock body can not be met, current can cover open drain and wash away roadbed, damage road surface.
