Description
Technical field
It blocks structure the invention belongs to hydraulic engineering field more particularly to a kind of mud-rock flow.
Background technique
Mud-rock flow is a kind of extremely strong geological disaster of harmfulness, 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.Most common Controlling Debris Flow measure is using structure of blocking, such as cable wire grid dam, lattice
Grid dam, sieve dam, comb teeth dam, water penetration arch dam etc., the structure common problem of blocking of these dam formulas are that ground excavates work
Journey amount is big, and dam body project amount 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 the erosion by rainfall and water 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.
Summary of the invention
The present invention provides a kind of mud-rock flow and blocks structure, is blocked structure by anchor cable constraint, and mud-rock flow flows through structure of blocking
Bulky grain stone is intercepted afterwards, and the decline of mud-rock flow carrying capacity, mud-rock flow damage capability reduces, so that mud-rock flow is effectively prevented,
Solve and need to excavate ground when building, construction condition is poor, and construction-time is long, project amount and it is at high cost the problems such as, this hair
It is bright to be suitable for water-rock debris flow, diluted debris flow, and the basement rock depth of debris flow gully Circulation Area is less than 10 meters.
The structure the technical scheme is that a kind of mud-rock flow is blocked, including anchor pole, drag-line, groove, gravity abutment, even rope,
In debris flow gully, the anchoring section of anchor pole protrudes into basement rock rockbolt installation, and one end of drag-line connects anchor pole, and the other end of drag-line connects
Connecing gravity abutment, the connection of the connection of drag-line and anchor pole, drag-line and gravity abutment can dismantle, groove is excavated in debris flow gully,
Several gravity abutments are placed in groove, gravity abutment is placed in the trench side by side, by even rope connection between gravity abutment.
The drag-line and Lian Suo is all made of steel wire winding.
Drag-line between the anchor pole and gravity abutment is arranged 2 or 2 or more.
The gravity abutment is precast member for reinforcing bar concrete.
A plurality of even rope is connected between the gravity abutment, the spacing of adjacent even rope is no more than 20cm.
One or more can be set in mud-rock flow structure of blocking in debris flow gully.
A kind of mud-rock flow is blocked the method for blocking of structure, this method comprises:
(1) Engineering geology and hydrogeology conditions for investigating and analysing debris flow gully, determine formation area, the Circulation Area of mud-rock flow
With accumulation area；
(2) drainage area for counting debris flow gully, the crest discharge of debris flow gully is determined according to meteorological data, according to mudstone
Ditch sectional dimension is flowed, mud-rock flow depth capacity is determined, the height of gravity abutment is determined according to mud-rock flow depth capacity；
(3) mud-rock flow blocks structure setting in the Circulation Area of mud-rock flow, and in debris flow gully internal drilling, drilling is in quincunx cloth
It sets, anchor pole is installed in drilling, groove is excavated in the debris flow gully in anchor pole downstream, places gravity abutment in the trench, with even rope
Adjacent gravity abutment is connected, 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 abutment provides drag for gravity abutment, and the stone that partial size is greater than steel wire mesh is blocked and accumulated, the stone of water and remaining partial size
Block flows away.
After a mud-rock flow, can there are two types of selection:
It blocks the stone of structure periphery first is that removing and being deposited in mud-rock flow, repairs impaired anchor pole, drag-line, even rope, gravity
Pier, structure of mud-rock flow blocking continue 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, again
Power pier selects new region to install anchor pole, excavates groove, places gravity abutment, connects anchor pole and drag-line, connects and connects between gravity abutment
Rope, structure of mud-rock flow blocking continue to play a role.
The present invention has the advantage that
(1) structure of blocking of the invention is built without excavating ground, is provided drag by anchor pole, is saved project amount, thus
Save engineering cost and construction time.
(2) gravity abutment of the 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 structure barrier mud-rock flow of blocking of the invention, weakens the scouring capability of mud-rock flow, from
And prevent and treat mud-stone flow disaster.
(4) structure of blocking of the invention can be dismantled, and after a mud-rock flow, can remove heap there are two types of selection
Long-pending stone or disassembly is blocked structure and the place installation that more renews, and structure of entirely blocking can reuse, economize on resources.
