Pile-raft composite shock isolation trough foundation structure under strong shock

Abstract

The invention provides a pile-raft composite shock isolation trough foundation structure under strong shock. The pile-raft composite shock isolation trough foundation structure under strong shock comprises a plurality of pile foundations, a plurality of shock isolation supporting seats and shock isolation troughs; the plurality of the pile foundations are distributed in a foundation; the shock isolation supporting seats are fixedly mounted at the pile top of each pile foundation; the shock isolation troughs are mounted on the shock isolation supporting seats; hot melt rubber layers are paved on the inner side walls of the shock isolation troughs; and rubber cushion layers, pebble buffering cushion layers, geogrids, rubber gravel cushion layers, composite geo-membranes, epoxy resin castinglayers, asphalt sand cushion layers and rafts are paved in the shock isolation troughs in sequence from bottom to top. The pile-raft composite shock isolation trough foundation structure under strongshock can effectively attenuate or eliminate seismic energy, avoid shaking and shock of an upper building and reduce the disaster caused by an earthquake. An earthquake resisting effect is outstanding; the construction is simple; the construction period is short; and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of anti-seismic engineering, and in particular relates to a pile-raft composite shock-isolation groove foundation structure under strong earthquakes. Background technique [0002] The piled raft foundation was proposed by Davis and Poulos in 1972. It refers to the foundation form of the rigid connection between the raft and the piles. It is often used in high-rise buildings in house construction. In recent years, with the rapid development of high-speed railways, nuclear power plants, and housing construction, piled raft foundations have been continuously applied to other construction fields. my country is an earthquake-prone country with frequent earthquakes, and the disasters caused by earthquakes are extremely serious, often endangering life and property safety. At the same time, the application of piled raft foundations faces new challenges in how to solve the problem of earthquake disasters. Therefore, it is ne...

AI Technical Summary

Problems solved by technology

However, for large-scale piled raft foundations, due to the characteristics of large scale and high rigidity, the isolation effect of only rubber isolation bearings is limited, and it is difficult to meet the seismic isolation requirements of large-scale piled raft foundations under strong earthquake conditions.
