Abstract
The invention discloses an in-trench water-stone separation siphoning-drainage debris flow control method. A series of permeable pipes are disposed in a trench in an area for formation or passage of debris flow, and drain siphons are connected to downstream ends of the permeable pipes. When the water level of rain flood reaches the siphoning level, water permeating into the permeable pipes is drained to the downstream safety trench through the drain siphons so that dynamic strength of the water in the trench is reduced. Using the method can effectively control formation and passage of debris flow and solve treatment methods for debris flow trenches on different scales, and control engineering is simple in construction and high in adaptability. Gravity flow is converted into full in-pipe flow under the action of siphoning drainage, and drainage efficiency is improved. Pipe sedimentation can be prevented under the suction action of siphoning. Diverted drainage in the case of high water level has low impact on the hydrological environment of the trench.
Description
Technical field
The present invention relates to a kind of debris flow technical method, relate in particular to a kind of water stone of avoiding in the formation of gully type mud-rock flow and the ditch of development and separate siphon drainage control mud-rock flow method.
Background technology
Mud-rock flow is the special mighty torrent that water is carried the solid matters such as a large amount of silt particles, stone secretly, and it breaks out suddenly, breaks with tremendous force, and has powerful destructive power, usually causes the great loss of lives and properties.The primary condition of debris flow formation can be summed up as: abundant water source, abundant bulk solids material, favourable watershed morphology and ditch bed longitudinal gradient.In these genesis of debris flow key elements, hydrodynamic condition is the environmental factor changing, and bulk solids material and basin condition are relatively-stationary factors.In debris flow formation process, can have powerful scouring capability because the mudstone carrying makes mighty torrent, gully erosion is involved in more mudstone, and the scale of mud-rock flow is developed gradually.Mud-rock flow comprises formation district, Circulation Area and accumulation area, and the engineering in general of control should be in the formation district of mud-rock flow and Circulation Area.If can control the formation district of mud-rock flow and the hydrodynamic condition of Circulation Area, just can effectively prevent the generation of mud-stone flow disaster.
Controlling Debris Flow engineering mainly contains the engineering that intercepts water, retains engineering, arranges and lead engineering, slope protection works etc., to control the generation of mud-rock flow and to work the mischief at present.The Engineering Control earth's surface flood runoffs such as utilization intercepts water, cut down hydrodynamic condition, need favourable orographic condition, are mainly applicable to the improvement of macrosolifluction ditch.Retaining mud-rock flow solid matter is the effective measures that reduce state of debris flow disasters, build check dam, the dam of blocking, hold the pool, storehouse or the depression of mud-rock flow, make bulk solids material not participate in mud-rock flow movement, also can be beyond the scope of guard plot, utilize depression, gully, barren beach, lakes and marhshes or build embankment, with enough large volume, mud-rock flow being introduced to village and hold, making it not produce harm.The current subject matter of retaining engineering existence is that engineering quantity restrictive condition large and that use is many.It is to utilize the engineering such as flood discharge channel, aqueduct that row leads engineering, and excretion mud-rock flow, controls the harm of mud-rock flow.Because the infiltration capability of mud-rock flow is strong, solid matter is abundant, drainage groove antiscour and anti-alluvial Capability Requirement are very high.Except engineering measure, by planting the plants such as Qiao, shrub, thick grass, give full play to that it is detained precipitation, conserves water and soil, the function such as regulated flow, occur or reduce its scale thereby reach prevention and prevent mud-rock flow, alleviate the object of its extent of injury.The feature of biological control measure is reduced investment, can improves natural environment, but the time of playing effectiveness is long, can not prevent and treat in time mud-stone flow disaster and occur.
Summary of the invention
