Description
Technical field
It blocks and system and blocks method the invention belongs to hydraulic engineering field more particularly to a kind of mud-rock flow.
Background technology
Mud-rock flow refers in mountain area or other cheuch deep gullies, the dangerously steep area of landform, because the natural calamities such as heavy rain are drawn
The landslide of hair and the special mighty torrent for carrying a large amount of silts and stone, mud-rock flow have sudden and flow velocity fast, stream
The features such as amount is big, and matter content is greatly and destructive power is strong, mud-rock flow, which occurs, can usually destroy by rush of water the means of transportation such as road and rail or even village
Town etc., brings about great losses.
Controlling Debris Flow engineering mainly retains engineering at present, row leads engineering, ecological engineering etc..It is most wide to retain engineer application
It is general, engineering is retained by retaining the solid matter in mud-rock flow to reduce state of debris flow disasters, builds check dam, blocking dam, stores library arch
Dam, broach dam, crib dam, rigid lattice dam, cable wire grid dam etc., make bulk solid mass be not involved in mud-rock flow movement, at present
Main problem existing for engineering of retaining be that quantities is big, ground, which excavates, etc. builds of high cost, and the scene of debris flow region is applied
Work condition is poor, and construction-time is long, and the restrictive condition used is more.
It is to drain mud-rock flow using engineerings such as flood discharge channel, aqueducts, control the harm of mud-rock flow that row, which leads engineering,.Due to mudstone
The erosiveness of stream is strong, solid matter is abundant, and the erosion resistibility and anti-siltation Capability Requirement to drainage groove are very high.
Ecological management engineering gives full play to it and is detained precipitation, conserves water and soil, the work(such as regulated flow i.e. by planting plants
Can, to reach prevention and the generation of prevention mud-rock flow or reduce its scale, mitigate the purpose of its extent of injury.Ecological management engineering
The characteristics of be that investment is small, natural environment can be improved, but the plant planted in cheuch does not have safeguard measure, is easy by rainfall
With the erosion of flow, growth and development state is poor, and the time played effectiveness is long, cannot effectively prevent the generation of mud-stone flow disaster.
Invention content
