Builders have begun to install anti-seismic devices of the Crimean bridge

18
The installation of shock-transmitters, devices that protect bridge structures from seismic impact, began on the road part of the Crimean Bridge, the Crimean Bridge information center reports.


This is one of the technical solutions in the project of the Crimean Bridge, which is being built in such a way that it will survive in the 9-scale earthquake

Builders have begun to install anti-seismic devices of the Crimean bridge


These devices are installed between the supports and spans, which provides a rigid connection structures for short-term seismic effects.



They allow the spans of the bridge to "breathe", that is, to freely move with the imperceptible movements caused by temperature conditions. And during an earthquake, shock transmitters operate and distribute the seismic load evenly over the supports
- told Igor Kolyushev, Technical Director of the Institute Giprostroymost - St. Petersburg.

On the Krymsky bridge, shock transmitters are used that take loads in 850 and 1500 kN (the calculated force in 85 and 150 tons). According to the information center, it is planned to install 760 shock transmitters on the road part of the Crimean bridge. On the railway part, the antiseismic fixing of the spans is performed by fixed and linearly movable support parts, so that during an earthquake, seismic forces are transmitted to intermediate supports.

Shock transmitters are one of the elements of protection of the Crimean bridge against seismic effects. The entire project was designed with consideration of potentially powerful earthquakes in the region.

    Type of shock absorbers, on a car, competently

      Interesting technology. The device is identical to the hydraulic shock absorber.

      This is necessary in our region. Large earthquake is quite possible. We hope that by the end of summer the road section will open.

        And also this device will work with close explosions .... which, in those places, the same alas, are not uncommon, the war "left" a lot of exploding metal there, especially TAM. Good system, what to say. Well done designers.

          Before the start of construction in these regions, sappers examine the bottom and issue a certificate.

            Unfortunately, they don’t find everything, and some part is brought by the current.

        instead of debating with clowns, Putin will go over the bridge and put a bullet in the election campaign of all candidates lol

        The bridge will eclipse Paul’s strawberry fields near the Moscow Ring Road and Ksenia’s protest. I guarantee.

    let's guys! in September in the ridge wassat I'm going to go to Sevastopol, I don’t want to bother with the ferry

    and it would not hurt to put something anti-ship and fluffy so that some would not even look in that direction

      and the point is, an old barge or boat wakes up to swim under the bridge and then bobnits,

        and what does it get bogged down at the 30 meter height of the canvas?

        it is an almost 9-story house height. Only if the barge is chock full of trotyl and itself will be built from it

        Such “ships”, as a rule, take coastal defense equipment for escort already upon leaving the port. It is not necessary to think that our intelligence EXTREMELY eats its bread in vain.

    These devices are installed between supports and spans, which ensures hard connection structures with short-term seismic effects.

    They allow bridge spans to "breathe", that is move unhindered with imperceptible movements caused by temperature conditions. And during an earthquake, shock transmitters trigger and distribute the seismic load evenly across the supports

    I am not a bridge builder, but these are, in my opinion, conflicting characteristics.

      The kinematics of this device retains the mechanical (but movable connection)
      True, the aggregate that in the picture works in two planes - and the forces caused by earthquake will affect the supports in three planes.

      No.
      It's all about the speed of movement of the working piston. Slow-maybe fast-no (if you explain it in a simple way).

    I looked at the picture of tightening high-strength bolts ... the builder himself .... guys, well, where is the tightening with torque wrenches?

    The antiseismic of the bridge is reliable! (9 points, this is not a pitching in a restaurant)!
