Description
Technical field
The invention belongs to underwater explosion-proof technology fields, are related to a kind of underwater blast resistance construction, multiple more particularly, to a kind of absorption type
Close energy dissipating explosion-protection equipment.
Background technique
With the rapid progress of modern science and technology, the global village of 21 century just like shapes.Due to history, religion, economy, political affairs
The reciprocal effect with the intricate factor such as geographical is controlled, human society faces many negative impacts, American politics scholar Hangzhoupro now
It is summarized as the conflict and confrontation of a kind of modern civilization by pavilion on a macro scale, thus in post-Cold War period, it gradually forms a kind of another
The form of war of class, specifically, being international terrorists attack action.
Past talks Dam safety, mostly the natural disasters such as weighting earthquake, flood, fresh to refer to less other than wartime special circumstances
Similar action of terror usually, the risk of artificial destruction.The U.S. is after " 911 " attack of terrorism, people's life, property and public
Facility all suffers from unprecedented threat.Many great installations of country, especially civilian installation, all may be terrorist
The main object of attack, dam belong to a kind of communal facility of large size, are subject to artificial destruction.Therefore, it is considered that it is insignificant
Artificial raid destroy, in the comprehensive new thinking of Dam safety, do not allowed again ignored, and one of the most effective ways are
It is to improve or strengthen dam security measures, becomes an important ring indispensable in dam general safety system.
Existing dam exterior protection technology has:
(1) more efficient stable dam type is used.In earth and rockfill dam, its impervious body of rock-fill dams has thick-layer stockpile and is not easy
Impaired, homogeneous dam is taken second place, and earth dam with inclined core is weaker, and grit dam is most weak.This safeguard procedures defend energy compared with based on, fixation
Power is lower.
(2) dam crest adds armored concrete antiknock body.World War II experience and lessons are drawn by Germany, add antiknock body in dam crest, with
Defend the explosion of bomb penetration.This safeguard procedures have certain protection effect to dam body itself, but cannot eliminate well underwater
Blasting shock wave can not effectively inhibit the rough wave effect caused by explosion.
(3) interior sloping core impervious body is added.In addition to the Asphalt Concrete Sloping Core wall impervious body being normally equipped with, added in dam together
Interior sloping core impervious body, plays the effect of double protection.
(4) discharge structure is built.A discharge structure is built between the layers of asphalt concrete for having face impervious body on dam,
Monolith every certain length is equipped with vertical fragmentation partition wall, just in case certain section of dam body breaks ring leakage, does not influence adjacent regions.
It can be seen that exterior protection technology at this stage is generally existing: cost is higher, equipment flexibility is poor, device
Detachability is poor, to having repaired, dam interference is big to wait improvements.
Summary of the invention
The present invention mainly solves technical problem present in the prior art；Provide the interference of a kind of pair of dam ontology compared with
Small, cost is relatively low；Installing and dismounting is simple, and explosion-proof effect is good；It is inhaled using reflector plate reflected-shock wave energy, using energy dissipating plate
It receives shock wave energy and combines explosion-protection equipment under Double-layer water.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:
A kind of absorption type composite energy dissipation explosion-protection equipment, reflector plate and energy dissipating plate including setting stacked on top of one another, reflection
Plate lower surface is Nian Jie with the upper surface of energy dissipating plate, the fixed multiple suckers in the lower surface of the energy dissipating plate；The reflection is flat
Plate is made of hard material；The energy dissipating plate is mainly made of elastic plate, and a wave in sequential like is set inside elastic plate
Shape wave metal plate, the corrugated metal plate are located in the space of elastic plate boundary composition；The sucker has to be inhaled through sucker
The venthole in attached face and non-adsorbed face, the venthole are equipped with air plug matched with its.
Preferably, the density of the reflector plate is 2500g/cm3-8000g/cm3。
Preferably, the elastic plate is rubber slab or cystosepiment.
Preferably, each wave crest of the corrugated metal plate is concordant with the upper end of elastic plate respectively, each trough point
It is not concordant with the lower end of elastic plate；The both ends of the corrugated metal plate are concordant with the both ends of elastic plate respectively.This energy dissipating is flat
Hardened structure can contact the first time elastic plate of explosion-protection equipment in shock wave and simultaneously compressive deformation occurs for corrugated steel plate, such as
Fruit does not use this preferred structure, and using other structures, for example corrugated metal plate is not each wave crest, trough and elastic plate
Upper and lower end it is concordant, the both ends of corrugated metal plate are not that whole is concordant with the both ends of elastic plate, and elastic plate can occur first
It is even closer to deform internal structure arrangement, limitation corrugated metal sheet deforms, and effect of energy dissipation can reduce.
Preferably, the making material of the corrugated metal plate uses spring steel.
As preferential choosing, the adsorption plane of the sucker has a plurality of fold striped, and the fold striped is radially distributed
In sucker suction face, the fold striped is strip solid projection or the hollow protrusion of strip.
Therefore, the present invention has the advantage that
1. explosion-protection equipment of the present invention work, shock wave travels to reflector plate upper surface first, due to reflector plate by
Hard material is made, and can reflect the explosion wave of a part；When remaining explosion wave reaches reflection through reflector plate
Plate lower surface, since reflector plate is made of hard material, reflector plate lower surface generates secondary reflection to explosion wave
The energy for weakening explosion wave again constitutes the bullet of energy dissipating plate when remaining explosion wave is passed to energy dissipating plate
Property plate and elastic plate in embed corrugated metal plate occur compressive deformation absorb portion of energy, just make to pass to dam surface in this way
Shock wave substantially weaken；Therefore, explosion-protection equipment of the present invention realizes reflection energy dissipating and deforms the combination of energy dissipating, compared to single
Reflect energy dissipating and single deformation energy dissipating, the energy dissipating explosion-proof effect enhancing of explosion-protection equipment of the present invention；
2. using absorption type structure, the dam surface protected sucker suction in needs when use.To suction when disassembly
Air this structure is passed through in disk to be detached from protection coating naturally, to by protection coating without any damage.
3. modularized design, adapts to curve form, the scope of application is wider.When more smooth by protection coating, according to quilt
The area in the face of protection can make this safeguard structure, and the case where for being curved surface by protection face, since reflector plate is hard
Material matter, the quantity for increasing explosion-protection equipment of the present invention can be taken and the mode of the area that reduces single explosion-protection equipment dam quilt
Protection face is arranged explosion-protection equipment.
