Description
Technical field
The present invention relates to a kind of culvert structures of the small-sized debris flow gully of highway span centre, and in particular to a kind of shaped form shop fixtures U
Type culvert structure.
Background technology
Gradual with 21 century country's the Belt and Road development strategy is implemented and the deep propulsion of strategy to develop western regions,
West area will show the newcoming advantage of opening, and west area Investment in Basic Facilities for Traffic construction will become China and improve
The emphasis of the people's livelihood.West area mud-rock flow region is more, mud-rock flow area crushing rock formation, and earthquake intensity is big, it is wide to destroy, vegetation compared with
Less, there is heavy rain when summer, the frequent generation of mud-stone flow disaster is bred in the expansion in addition human activity degree deepens continuously.
Mud-rock flow directly impact and undercutting are that bridges and culverts damages important function power type.Especially highway culvert is as friendship
Lead to drainage system important in transport and ensures roadbed continuously not by one of the important structure of flood erosion or invasion, and in west
Portion's local highway is higher with ratio in using；The mud-rock flow that western mountainous areas is formed have outburst suddenly, last that of short duration, the oncoming force is fierce
Violent and the features such as quickly cause disaster, when outburst, can go out gradually to accumulate material resource and huge energy a large amount of early periods in abrupt release, generate pole
Big destructive power, and culvert import is nearby mud-rock flow collection region, debris flow velocity and flow are all bigger, so when outburst
When mud-rock flow, often since culvert design is unreasonable or culvert headroom is insufficient or culvert is imported and exported and shop fixtures is not taken and effectively arranged
It applies, causes seriously wash away or deposit blocking or deeper sapping trace, the overall stability for jeopardizing culvert even blocks for a long time
The normal operation of traffic causes large area roadbed to be destroyed by rush of water.Therefore, debris flow region culvert flow section how is reasonably selected
Structure type to meet the Buried culvert under roadbed under limited topography situation be mud with preferable resistant abrasion ability and best discharge capacity
The major issue that must be solved when the novel culvert design in rock glacier area.
