Vibration isolator for building manure tank

Abstract

The invention discloses a building trough vibration isolator. The vibration isolator comprises a vibration isolator body. The vibration isolator body is arranged in a trough which is reserved between one side of a building and the side wall of a foundation pit. The vibration isolator body comprises a waterproof layer, an elastic damping layer, a concrete layer and a rubber base plate. The waterproof layer, the elastic damping layer and the concrete layer are arranged in the trough and cling to the trough. The rubber base plate is arranged between the concrete layer and soil on the bottom of the foundation pit. By means of the trough space design of the vibration isolator, the structure design is reasonable, the engineering implementation is easy and the vibration which transmits from the side wall of the foundation pit to the building foundation can be effectively isolated under the premise of guaranteeing the safety of the building.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and mechanical engineering, and relates to a device for vibration isolation of rail transit ground lines, in particular to a vibration isolator for a building fertilizer tank. Background technique [0002] When building buildings on the land close to the ground line of rail transit, the primary problem is the environmental vibration and noise pollution caused by train operation. For vibration problems, the available methods can be roughly divided into two categories, one is track vibration isolation; the other is non-track vibration isolation. Wherein, rail vibration isolation refers to vibration isolation on rails, and existing methods include vibration isolation by means of vibration-damping fasteners or vibration-damping ballast beds. Non-track vibration isolation refers to the method of vibration isolation in the area between the track and the building, as well as on the building i...

AI Technical Summary

Problems solved by technology

Many types of polyurethane materials have a weakness, that is, the partial collapse of their internal frame structure after overloading will cause them to lose their bearing capacity until the material is compacted, which is extremely unfavorable for side wall restraint and building safety protection under seismic waves

[0009] In short, how to make good use of the space of the fertilizer tank to carry out a reasonable vibration isolation design for the vibration of the transmission path 1 has so far been scarce, and it is still a research problem for non-track vibration isolation of buildings around the ground line
