Description
Technical field
It takes precautions against natural calamities field the utility model is related to mud-rock flow, more particularly to a kind of novel flexible mud-rock flow suitable for mountain area
It blocks device.
Background technology
The extreme weather events such as EI Nino change atmospheric circulation, cause the diastrous weathers such as heavy rain, flood；Global warming
Increase with extreme hot event, causes deglaciation, frozen soil layer freeze thawing aggravation.Under the influence of these extreme climates and environment,
Mountain area mud-stone flow disaster takes place frequently, and the Problems of Disaster Preparedness And Reduction of mud-rock flow increasingly comes into the picture.Mud-rock flow have it is sudden with
And the features such as flow velocity is fast, and flow is big, and matter content is greatly and destructive power is strong, generation mud-rock flow can usually destroy by rush of water the traffic such as road and rail
Facility even villages and small towns etc., brings about great losses.Nowadays common mud-rock flow block device there is protecting against shock effects it is limited, apply
When expenses of labour, consumptive material is more, high cost problems.
Invention content
The purpose of this utility model is that the deficiency for device of blocking for existing mud-rock flow, provides a kind of protecting against shock effect
Good, consumptive material is few, construction is simple, durability is good and the economic novel flexible mud-rock flow suitable for mountain area is blocked device.
The applicable scene of the utility model is：The mud-rock flow of the important buildings such as mountain area and neighbouring no residential block takes place frequently ground
Point.Because not having residential block in mountain area, according to this feature, setting the utility model novel flexible mud-rock flow is blocked device.It should
Device allows the little particle in mud-rock flow to break through device a distance of blocking, such design can when blocking mud-rock flow
To reduce the dynamic response of whole device, and a large amount of material can be saved.
Scene after the mud-stone flow disaster of mountain area is investigated and finds mud-rock flow after moving a distance, mud-rock flow dragon
There is apparent sorting effect at head.This sorting effect is very unfavorable for the stress for device of blocking, because through excessive
After selecting effect, mud-rock flow moves up the resultant force for device impact force of blocking, this will generate bigger to the root for device of blocking
Moment of flexure, to make to block, device destroys.
It is blocked device compared to traditional rigid gravity type using device flexible of blocking, dynamic response is lower, internal force
Smaller.From the point of view of the result of calculation of numerical simulation, the counter-force of bearing can substantially be reduced to rigid gravity type and block the 1/ of device
3-1/5。
Meanwhile device is entirely blocked in order to prevent when by mud-rock-flow-impact, since the gear of flexible apparatus is fixed at both ends
Wall loss of stability and make whole device unstable failure, fix the Gravity Retaining Wall of flexible structure at device both ends of blocking
Wall heel slab is arranged in inside, and the stability of device is maintained using the passive earth pressure of the soil body.Because passive earth pressure is actively native
10 times or so of pressure, so the Gravity Retaining Wall through this design can ensure enough when by mud-rock-flow-impact load action
Stability.
The utility model combines above-mentioned 3 actual conditions, and innovative proposes a kind of novel flexible suitable for mountain area
Mud-rock flow is blocked device, which includes two opposite Gravity Retaining Walls in position, upper tightly lower sparse between two Gravity Retaining Walls
Several flexible structures of layered arrangement；The flexible structure is by spring, cylindric engineering plastics shell, sealing cement and anchoring end
Composition；The spring is located in cylindric engineering plastics shell, and Seal Oil is filled between spring and cylindric engineering plastics shell
Cream；The anchoring end is fixedly connected with spring in cylindric engineering plastics enclosure；Entire flexible structure passes through both ends
Anchoring end is fixedly connected with split bolt of the pre-plugged in the Gravity Retaining Wall of both sides.
Further, the density degree of the flexible structure arrangement regards engineering importance and the impulsive force of mud flow of estimation is big
Depending on small；The interfloor distance of layering is not less than 15mm；Spacing between arbitrary flexible structure flexible structure adjacent thereto is not less than
15mm。
Further, the rigidity of the spring is not less than 100N/mm, is not more than 400N/mm.
Further, Screw arbor with nut at both-ends of the split bolt by diameter not less than 16mm and stopping positioned at Screw arbor with nut at both-ends both ends
Water ring forms.
Further, wall heel slab is arranged in bottom inside in the Gravity Retaining Wall, and the length of wall heel slab is not less than 2m.
Further, when the span for device of blocking is smaller, the wall heel slab of both sides Gravity Retaining Wall can be connected as one
It is whole.
The utility model has the beneficial effects that：Flexible structure in utility model device has significant energy consumption effect,
When device of blocking is by mud-rock-flow-impact, flexible structure deforms, dissipation impact energy, reduces device of entirely blocking
Dynamic response.In practical mud-rock flow flow process, because of mudstone classification effect so that bulky grain concentrates on mud-rock flow dragon
The top of head.According to this phenomenon, by the closeer of the flexible structure arrangement of upper end, the flexible structure arrangement of lower end is relatively dredged, this
Sample is conducive to improve stress performance of device when by mud-rock-flow-impact of entirely blocking.When entirely blocking device by mud-rock flow
Impact when, the Gravity Retaining Wall at both ends maintains entirely to block the stability of device using the passive earth pressure under wall heel slab, from
And the device that ensures to block is with reliable stability, it is ensured that the effect of blocking for device of blocking is not fully exerted.Through this design
Novel flexible mud-rock flow is blocked device, and when by mud-rock-flow-impact, device is more uniformly stressed, and dissipate more impact energys
Amount, the Gravity Retaining Wall at both ends, with enough stability, can ensure that blocking for device of blocking when being acted on by mud-rock-flow-impact
Keep off effect.Also, the flexible mud-rock flow due to being provided in mountain area is blocked device, scarcity, does not have important building nearby
And structures, other barricades can not be built between the Gravity Retaining Wall of both ends, device allows mud when blocking mud-rock flow
Little particle in rock glacier breaks through device a distance of blocking.Design in this way can greatly reduce the dosage of material and apply
The difficulty of work.
