Referring to fig. 1 to 8, the present embodiment provides a square periodic structure for urban water storage, irrigation and vibration reduction, which is used in the fields of urban water storage, irrigation and vibration reduction; specifically, the water storage function is realized by the following means: rain, snow and other precipitation enter the periodic structure through a permeable pavement and greening on the ground or enter the periodic structure through a confluence ditch, and flow among the units through water exchange holes among the units of the periodic structure, so that a stable water storage function is realized; the periodic structure needs to store more than 50 percent of water, the water storage is less than 50 percent, water should be supplemented manually, the period number perpendicular to the road direction is not less than 2, and the suggested period number is 3-6; the irrigation function is realized by the following modes: the cover plate is reserved with a water outlet hole, is provided with irrigation equipment or a siphon, and pumps out the stored water through an auxiliary water pumping device to the ground for irrigation or realizes the irrigation function without external force through the siphon action; the vibration reduction effect of the periodic structure is calculated by adopting a phonon crystal theory based on fluid-solid coupling, a square lattice is adopted, a periodic boundary condition is applied to the boundary of the periodic structure unit, the Bloch theory is utilized to sweep a first simplified Brillouin area of the square lattice, the band gap of the periodic structure unit is solved, the vibration energy of the frequency within the band gap range is greatly inhibited, and the vibration reduction function of the periodic structure is further realized, the vibration of the vibration frequency within 400Hz-1000Hz can be greatly inhibited through reasonable design of the periodic structure, and the vibration of the frequency within 100Hz can be inhibited to a certain extent.
In conclusion, the square water storage, irrigation and vibration reduction periodic structure for the city, provided by the invention, can solve the problem that traffic vibration influences the surrounding environment and the problem that the water storage device in the current sponge city construction is single in 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.
