Description
Technical field
It blocks structure and method of blocking the invention belongs to hydraulic engineering field more particularly to a kind of mud-rock flow.
Background technology
Mud-rock flow is a kind of geological disaster that harmfulness is extremely strong, and Mountain In China area is big, and alpine terrain is steep, concentrates rainfall
Easily cause mud-rock flow, the basin of typical mud-rock flow generally comprises to form area, Circulation Area, accumulation area, and debris flow control works are general
Setting is forming area or Circulation Area.Current most common Controlling Debris Flow measure is using structure of blocking, such as cable wire grid dam, lattice
The structure common problem of blocking of grid dam, sieve dam, broach dam, water penetration arch dam etc., these dam formulas is that ground excavates work
Journey amount is big, and dam body quantities is also larger, and construction condition is poor, and construction-time is long.In addition also flexible steel wire, steel construction block
The control measures such as barricade, both technical measures are huge using steel material, and cost is high.Ecological management engineering passes through kind
Plant is planted, it is given full play to and is detained precipitation, conserves water and soil, the functions such as regulated flow, to reach prevention and prevent mud-rock flow hair
Life reduces its scale, mitigates the purpose of its extent of injury.The characteristics of ecological management engineering, is that investment is small, can improve nature ring
Border, but the plant planted in cheuch does not have safeguard measure is easy to be corroded by rainfall and flow, growth and development state compared with
Difference, the time played effectiveness is long, cannot effectively prevent the generation of mud-stone flow disaster, and the auxiliary for generally only doing debris flow is arranged
It applies.

Adjacent gravity abutment connects anchor pole and gravity abutment with drag-line；
（4）Mud-rock flow flows through mud-rock flow and blocks structure, and anchor pole provides withdrawal resistance, and withdrawal resistance passes to drag-line, and drag-line pulls gravity
Pier provides drag for gravity abutment, and the stone that grain size is more than steel wire mesh is blocked and accumulated, the stone stream of water and remaining grain size
It walks.
After a mud-rock flow, can there are two types of selection：
It blocks the stone of structure periphery first, removing and being deposited in mud-rock flow, repairs impaired anchor pole, drag-line, even rope, gravity abutment, mud
Structure of rock glacier blocking continues to play a role；
Second is that dismantling the connection of drag-line and anchor pole, company's rope between gravity abutment is dismantled, repairs impaired drag-line, even rope, gravity abutment,
It selects new region that anchor pole is installed, excavates groove, place gravity abutment, connect anchor pole and drag-line, connect rope, mud between connection gravity abutment
Structure of rock glacier blocking continues to play a role.
The invention has the advantages that：
（1）The structure of blocking of the present invention is built without excavating ground, is provided drag by anchor pole, quantities is saved, to save
Engineering cost and construction time.
（2）The gravity abutment of the present invention is prefabricated components, is completed in factory, and remote location, execution conditions are suitable for
The debris flow gully of difference, construction environment difference.
（3）Bulky grain stone in the structure barrier mud-rock flow of blocking of the present invention, weakens the scouring capability of mud-rock flow, from
And prevent mud-stone flow disaster.
（4）The structure of blocking of the present invention can be dismantled, and after a mud-rock flow, can remove heap there are two types of selection
Long-pending stone or dismounting is blocked structure and the place installation that more renews, and structure of entirely blocking can reuse, economize on resources.
