[0024] The utility model is described in detail below in combination with the drawings and specific embodiments. Embodiment
[0025] As Figures 1-3 shown, the embodiment provides a support suitable for horizontal isolation and vertical isolation of subway vibration, which comprises a horizontal isolation support 1, a platform upper connecting plate 2, a vertical vibration isolation support 3, a horizontal anti-rotation system and a platform lower connecting plate 7, the horizontal isolation support 1 is arranged on the platform upper connecting plate 2, the vertical vibration isolation support 3 comprises an upper cover barrel 21 and an elastic element 32 connected with the upper cover barrel 31, the top of the upper cover barrel 31 is connected with the bottom of the platform upper connecting plate 2, the lower end of the elastic element 32 is connected with the platform lower connecting plate 7, the two ends of the horizontal anti-rotation system are connected with the platform upper connecting plate 2 and the platform lower connecting plate 7 respectively, and the horizontal anti-rotation system can change with the compression or stretching of the vertical vibration isolation support 3.
[0026] The horizontal isolation support 1 in the support suitable for horizontal isolation and vertical isolation of subway vibration of the utility model plays the function of reducing the upper horizontal isolation, the vertical vibration isolation support 3 plays the function of reducing the vertical environmental vibration, and the horizontal anti-rotation system plays the function of resisting horizontal rotation, when the structure suffers from horizontal earthquake, the horizontal isolation support 1 at the top will deform horizontally, and the seismic energy is dissipated through deformation, at this time, the vertical vibration isolation support 3 between the top connecting plate 1 and the bottom connecting plate 2 will not deform or move, at this time, the horizontal anti-rotation system will play the function of resisting the horizontal rotation of the support and bear the horizontal force transmitted by the horizontal isolation support 1, when the structure suffers from the vertical vibration transmitted by the environmental vibration such as subway, since the vertical stiffness of the horizontal isolation support 1 is much greater than that of the vertical vibration isolation support 3, at this time, the elastic element 32 in the vertical vibration isolation support 3 will deform vertically, reducing the vertical vibration of the upper structure, at this time, the horizontal anti-rotation system also moves downward with the compression of the elastic element 32, and does not hinder the vertical deformation of the elastic element 32 in the vertical vibration isolation support 3.

When the structure is subjected to horizontal earthquake, the horizontal anti-rotation system composed of the vertical support sliding cylinder 5 will play a role of resisting horizontal rotation of the support, and the vertical vibration isolation support 3 will not deform or move. When the structure is subjected to vertical vibration transmitted from environmental vibration such as subway, the upper cylinder 51 and the lower cylinder 53 move vertically relative to each other through the polytetrafluoroethylene plate 52, which does not hinder the vertical deformation of the elastic element 32, and at the same time provides a vertical sliding guide function.
