Description
Technical field
The invention belongs to shed hole structure design field more particularly to a kind of solid-liquid separating shed hole structure of anti-mud-rock flow,
Further relate to its construction method.
Background technique
Southwestern China area mountain Gao Gushen, the hillside gradient is steep, and building for subgrade river side causes massif broken, loose media heap
Product.In addition, southwest precipitation is abundant, the geological disasters such as landslide, mud-rock flow easily occur, highway, bridge and other bases are set
It applies etc. and to cause to seriously endanger.Mud-rock flow refers in mountain area or other cheuch deep gullies, the dangerously steep area of landform, because heavy rain, sudden and violent
The landslide of snow or the initiation of other natural calamities and the special mighty torrent for carrying a large amount of silts and stone.Mud-rock flow has prominent
The features such as right property and flow velocity are fast, and flow is big, and matter content is big and destructive power is strong.
After hangar tunnel refers to open cut cutting, the ceiling frame of freely-supported, and barrel made of backfill are constructed, the tunnel of open cut tunnel scope is belonged to
Road.Substantially similar using the condition and open cut tunnel of hangar tunnel, structural integrity is poorer than open cut tunnel, but due to ceiling and inner-outer wall freely-supported,
Therefore the requirement to ground is relatively low.Hangar tunnel is a kind of road knot for effectively preventing the natural calamities such as Falling Rocks, mud-rock flow
Structure.
Currently, entering hangar tunnel for the mud-rock flow for preventing massif from being formed, green flexible protective can be generally carried out in side slope, together
When in high slope every mono- step of 8m simultaneously intercepting ditch is set, make side slope rainwater or infiltration flow into preset chute,
Last one of intercepting ditch is located on the outside of a plate type retaining wall, prevents water flow from crossing peg board body, influences shed hole structure safety.Although
There is numerous shed hole structures to pay attention to the destruction for preventing mud-rock flow to shed hole structure from the angle of energy dissipating at present, often only individually
Consider the flow velocity for reducing mud-rock flow, the functions such as retention mud-rock flow.Since mud-rock flow mainly includes the stone and fluid of solid
Silt, thus they hazard ratio it is common flood it is bigger, can reduce the harm of mud-rock flow if separating stone with silt.Cause
This, the stone and silt for including in mud-rock flow can be separated by being badly in need of one kind now, and can lower the hangar tunnel knot of the flow velocity of mud-rock flow
Structure.
