The invention discloses a mounting structure and a construction method of an isolation bearing in existing building base isolation reinforcement. The mounting structure of the isolation bearing comprises an upper pier, an isolation bearing body and a lower pier. The isolation bearing body is arranged between the upper pier and the lower pier. The upper pier is connected with the isolation bearingbody through an upper portion connection measure, and the lower pier is connected with the isolation bearing body through a lower portion connection measure. The upper portion connection measure and the lower portion connection measure both comprise pre-buried plates, anchoring ribs, bolt locking parts, grouting material mixtures, bolt assemblies and isolation bearing connection plates. The mounting structure and the construction method overcome the defect that a traditional pre-buried sleeve connection mode cannot adapt to isolation reinforcement construction, the bolt locking parts and the bolt assemblies are adopted to solve the problem of precise positioning of bolt holes, the isolation bearing is protected effectively, and the mounting and connection levels of the isolation bearing are improved.

The invention provides an artificial forage for larvae of Holotrichia parallcla.
