Description
Technical field
It takes precautions against natural calamities field the invention belongs to civil engineering, and in particular to a kind of pneumatic back springing type half actively anti-mud-rock-flow-impact dress
It sets.
Background technique
Often maximum probability is along with secondary disaster and other Derived Hazards for the generation of mud-stone flow disaster, in its generation area
Ecology, environment and society etc. cause most directly to destroy.Over the years, the outburst of mud-stone flow disaster without exception to people
Production, life cause serious threat, hinder the development of society.
It is well known that it is to mitigate mud-rock flow to endanger most effective arrange to building that Architectural foundation, which avoids mud-rock flow danger area,
It applies, but due to resident, soil and policy etc., inevitably there is large stretch of house by disaster area in potential mud-rock flow, it is first
Selecting hazard-relief strategy is to take engineering measure, such as drainage groove, debris dam and flexible barrier, however mud-rock flow has randomness, often
Rule engineering measure is unable to ensure normal performance effect.Currently, existing related fields researcher proposes novel shock-resistant masonry
The methods of structure and use new material stiffening frame structural column, these methods belong to passive enforcement strategy mostly.Due to mud
The sudden and randomness of rock glacier, the size of unpredictable impact load and direction, passive enforcement strategy to the protection of structure still
There is deficiency.
Chinese patent CN107012969A discloses a kind of new masonry constructional device that can resist mud-rock-flow-impact, including
Steel grating net, Damped Sandwich layer, nonlinear dampling alloy sheet and rubber cushion blocks, the device are wrapped in the wall of masonry structure, steel outside
Grid is connect by modes such as drag-lines with basis, floor plates.It is Damped Sandwich layer, Damped Sandwich between steel grating net and wall
There are several square holes, one nonlinear dampling alloy sheet of installation and rubber cushion blocks in each square hole on layer.In rushing for mud-rock flow
It hits under effect, steel grating net intercepts mud-rock flow, avoids the fierce impact to masonry structure transverse direction.Chinese patent
CN108360465A discloses a kind of wedge-shaped mud-rock flow shunting and blocks device and its construction method, which includes arc-shaped barricade
With two wing barricades；Arc-shaped barricade is located at the front end of whole device, the symmetrical fixed-wing barricade in two sides；Arc-shaped barricade it is interior
Portion and the inside of wing barricade are respectively provided with prestressing without bondn system；Prestressing without bondn system includes that several vertical soap-free emulsion polymeizations are pre-
Prestress steel strand device, un-bonded prestressed steel strand device are made of steel strand wires, anchorage and bellows；Arc-shaped barricade and the wing
The bottom of barricade is provided with sole plate, and uplift pile basis is added under the sole plate with prestressing without bondn system.
However, prior art has disclosed device, do not have high performance-price ratio, safe and applicable, inflexible, mud-rock-flow-impact flowering structure is supported
Drag is insufficient.
