The present application provides an operating sound eliminating device for a semi-active engine mount of a vehicle, in the configuration of an electromagnetic valve for opening and closing an air chamber of the semi-active engine mount, a plurality of layers are adopted for an upper stopper, so that not only the air tightness and durability of the upper stopper can be improved, but also the impact when the upper stopper hits a valve housing can be absorbed while reducing noise.

This invention proposes a novel steel structure seismic-resistant block, fixedly installed at the bottom of a steel box girder and on the inner side of the pier support. It includes a damping plate and a stiffening plate. The damping plate is fixedly mounted on a fixed frame composed of stiffening plates, facing the pier support. The fixed frame is fixedly mounted at the bottom of the steel box girder. The damping plate includes a plate bearing and evenly distributed nails on the plate bearing. Both the plate bearing and the nails are made of neoprene rubber. This invention achieves its damping function by using a neoprene rubber damping plate instead of the original elastic structure. It serves as a primary energy-dissipating structure, with a stiffening plate behind the damping plate acting as a secondary energy-dissipating structure. This multi-layered energy-dissipating structure results in better overall damping performance, effectively absorbing and attenuating vibrations, and reducing the impact of lateral slippage of the superstructure on the pier.

The utility model relates to the technical field of water interception ditch, concretely to a water interception ditch with water and dirt separation structure, it is a water interception ditch with water and dirt separation structure, purpose solves the traditional water interception ditch usually only has single drainage function, the leaves and other sundries carried by rainwater are directly drained into natural water body, not only easy to cause the drainage pipeline of water interception ditch to be blocked, still can cause the problem of surrounding environment pollution, therefore enhanced the use efficiency and effect of water interception ditch, including water interception ditch body and apron, the water interception ditch body sets up as the recess shape, the apron sets up at the top of water interception ditch body, the water interception ditch body is by concrete pouring and is formed, the water interception ditch body is provided with separation mechanism, the separation mechanism still includes separation board and support plate, the apron top end is provided with multiple groups of drain holes, the separation board periphery inner wall is provided with multiple groups of separation through -hole, water interception ditch body inner wall left and right ends fixed mounting has support plate.
