Abstract
The bottle stopper type anti-shock dam has arched dam stoppers, which have no connection with dam foundation and stop dam mouths comprising dam bottom and necked dam shoulder under the pressure of water. It can resist strong earthquake stress to maintain the completeness and to prevent flood.
Description
Affiliated field: the shockproof anticracking of dam.
Technical background: from ancient times to the present, ladder type dam, T-shaped dam, loose rock dam, concrete gravity dam, the arch dam that people use all can't solve dam and prevent shaking doughtily, preventing the fission problem.
Summary of the invention: it is different fully that the present invention and above listed various dams are built method, adopts the arch plug dam that does not link to each other with ground to clog the method for the Ba Kou that is made up of weir, bottleneck formula shoulder dam, and what solve dam well prevents shaking doughtily, preventing the fission problem.
Description of drawings: Fig. 1 is a structural representation of the present invention.
The specific embodiment: bottle stopper type anti-shock dam, may flow powerfully because of seismic forces damages the height big flood cause hundreds of rice for avoiding reservoir dam, the appearance that momentariness drills the downstream for the fearful situation of vast sea proposes a kind of new dam type.
As Fig. 1, make use of momentum according to bank, we can establish the cofferdam and build bottleneck formula shoulder dam (2), repair bridge pier as fence and build weir (1), and its length, height are highly determined by retaining, but main stress point should be on the shoulder dam.Plug dam (3) can be prefabricated in the upstream earlier, and the weir place assembling of wafting is with the reduction of erection time.Each bonding surface should adopt cambered surface.
This type dam under earthquake stress, fission contribution, all has the ability that stops a high big flood Pentium and go out at each.Because the duration is short, manufacture difficulty is relatively littler, so though bigger than existing dam type, cost is not necessarily high.
Claims (1)
1, a kind of bottle stopper type anti-shock dam is characterized in that movable arch plug dam is formed by dam, the end, bottleneck formula shoulder dam.
