Technical Field

The invention relates to the technical field of building shock insulation, in particular to a vibration isolator for a pipeline support.

Background

The thinking of building shock insulation and utility tunnel pipeline shock insulation is more similar, and building shock insulation is the earthquake energy that reduces the interact between ground and the superstructure and reduce the input, and utility tunnel pipeline shock insulation is the earthquake kinetic energy and the interact that transmit to the body again for reducing the soil body and pass to the concrete structure, all is the earthquake kinetic acceleration input that reduces the reception. The transfer process of seismic motion can be represented as: the method comprises the following steps of soil body-underground comprehensive pipe gallery concrete structure-support (pier) -pipe body. It can be seen that the acceleration response of the tube will vary as long as the shock insulation is provided at least at one location during the transfer. The acceleration at the pipe body is transmitted from the support, the support is easy to slide and deform, and the design of carrying out shock insulation on the support has practical shock insulation significance.

When not shock insulation, the pipeline relies on the static friction force that produces between body dead weight and the support to maintain the original state, and the pipeline begins to take place the displacement after the inertial force of earthquake effect surpasss maximum static friction force, has horizontal, axial displacement and vertical runout scheduling problem that probably takes place during it, all is the condition that can lead to the pipeline to go wrong.

Generally, the pipeline is directly placed on the groove part of the support, and the support form can be changed, the limit of the transverse displacement is increased, and a pipe buckle is arranged in the vertical direction as the limit, as shown in fig. 1.

Seismic isolation considerations are generally seismic isolation mounts and dampers. The support needs to be able to support the weight of the structure for a long time, i.e. to have sufficient vertical stiffness. The damper converts the energy of the earthquake into elastic-plastic strain energy and consumes the elastic-plastic strain energy. Laminated rubber mounts are generally considered in construction. The laminated rubber support is manufactured by mutually and alternately superposing an interlayer thin steel plate and a thin rubber sheet. The rubber provides lateral stiffness and the steel plate provides vertical stiffness, as shown in fig. 2.

Researchers invented lead core rubber vibration isolation bearings in 1975. The original rubber shock insulation support comprises a steel plate and rubber wrapped outside the steel plate. The laminated steel plates provide sufficient vertical stiffness and the rubber provides a restoring force in the horizontal direction. However, this mode does not provide sufficient damping, and the lead is inserted in the middle of the rubber mount to compensate for the lack of damping. On one hand, the lead core can provide enough horizontal rigidity when no or small earthquake occurs, on the other hand, the lead core has plasticity under the action of a large earthquake, the horizontal rigidity is reduced due to the yield of the lead core, the structural period is prolonged, and damping is provided for dissipating energy. The lead rubber bearing is widely applied to the building foundation and the bridge bearing, and the structure of the lead rubber bearing is shown in figure 3.

At the moment, the reaction of the pipeline is still limited by the friction force between the pipeline and the pipe fastener and the support. Although the movement of the pipeline is limited, the pipeline moves along with the underground comprehensive pipe gallery structure after being fixed on the support, and most of the acting energy transmitted to the structure by earthquake motion is transmitted to the pipe body.
