A prefabricated assembly type vibration isolation and energy dissipation barrier

Abstract

The present invention provides a prefabricated assembly type vibration isolation and energy consumption barrier, which includes at least one vibration isolation and energy consumption wall. Collision type energy consumption device, the vibration isolation energy consumption box is located between the suspension collision type energy consumption devices; the suspension collision type energy consumption device includes several suspension collision type energy consumption units, the suspension The collision energy consumption units are connected to each other; the suspension collision energy consumption unit includes an upper spring, a suspension collision block, a lower spring, and a collision energy-absorbing layer, and the suspension collision block is located between the upper spring and the lower spring Between, the upper spring is located above the lower spring. The prefabricated and assembled vibration-isolation and energy-dissipating barrier of the present invention can not only hinder the propagation of vibration waves on the propagation path, but also consume the transmitted vibration energy, so as to achieve the purpose of vibration isolation and vibration reduction.

Description

technical field [0001] The invention belongs to the field of vibration isolation and vibration reduction engineering, in particular to a prefabricated assembly type vibration isolation and energy consumption barrier. Background technique [0002] With the in-depth development of urbanization, the environmental vibration caused by human activities such as rail transit, construction machinery and factory mechanical vibration will have a negative impact on the life and work of nearby residents, precision instruments and equipment, and the safety of ancient building structures. Many experts and scholars at home and abroad have paid more and more attention to solving the above-mentioned environmental vibration problems, and various effective vibration isolation and vibration reduction measures have been adopted one after another. [0003] Setting up vibration isolation barriers is one of the effective methods to solve the above environmental vibration. There are many types of vi...

AI Technical Summary

Problems solved by technology

The above-mentioned vibration isolation barrier uses the change of the propagation path of the vibration wave, and relies on itself and the soil around the barrier to consume energy. Sometimes it is difficult to achieve the expected vibration isolation and vibration reduction effect, or the vibration isolation barrier itself is not deep enough, Difficulties in excavation and construction
