Background
At present, urban traffic is rapidly developed in China, vibration pollution is caused increasingly frequently, and the quality of life of residents and the use of precision instruments are seriously influenced. The measures for traffic vibration control are roughly divided into two types, namely vibration reduction on a seismic source and vibration reduction on a protected building. For example, vibration damping asphalt pavement is designed for vibration damping of seismic sources, and vibration damping supports and the like can be arranged under a protected building for vibration damping of the protected building. However, these methods all have drawbacks: such as poor durability of vibration damping measures, short service life, high cost and difficulty in implementation for already built buildings. On the other hand, in sponge city construction, the development of water storage devices is a major problem, and various water storage devices have single functions and relatively high cost.
In order to overcome the defects that vibration reduction facilities are poor in durability, short in service life, high in manufacturing cost and difficult to realize the built buildings, the patent provides a periodic structure taking water as a filling material and simultaneously serving as a water storage device in sponge city construction. The water storage vibration reduction periodic structure can generate a frequency band gap with a certain width on the premise of reasonably designing geometric parameters and material parameters, can cover the dominant frequency of traffic vibration, can greatly inhibit the vibration response of a protected building, and achieves the purpose of eliminating the environmental vibration interference.

In conclusion, the water storage and vibration reduction device provided by the invention can solve the problem that the influence of traffic vibration on the surrounding environment and the water storage device in the current sponge city construction have single function. The damping function is determined by the band gap characteristic of the periodic structure, and other damping materials and additional structures are not needed. The band gap is obtained by calculation of a phononic crystal fluid-solid coupling theory, and the isolation of the vibration of the specified frequency band is realized. The water storage and irrigation capacities can be adjusted by combining different numbers of periodic units. The periodic structure can greatly inhibit the vibration with the vibration frequency of 400Hz-1000Hz and can inhibit the vibration with the frequency within 100Hz to a certain extent through reasonable design.
