Shock isolation device applied to tunnel

By setting up domes and water barriers on the periphery of the tunnel and setting up connecting strips on both sides of the storage box to prevent water flow erosion. Combined with the design of speed reduction tanks and hydraulic oil, the problem of the loss of filling materials and the vibration frequency of the existing tunnel isolation device cannot be reduced, achieving better shock absorption effects.

AI Technical Summary

Technical Problem

When existing tunnel shocks are faced with external vibrations, the filling material is easily washed away, resulting in a reduced shock isolation effect and unable to effectively reduce the vibration frequency.

Method used

A shock isolation device is designed to prevent the infiltration of water from directly contacting the tunnel by setting up a dome and a water barrier on the periphery of the tunnel, and to set up connecting strips on both sides of the storage box to prevent water flow from eroding the storage box, and at the same time, the storage box is filled with shock absorbing materials.

Benefits of technology

It effectively prevents the erosion of the storage box by water flow, maintains the dry state of the filling, extends the shock absorption effect, and reduces the vibration frequency and improves the shock isolation effect through the combination of the speed reduction tank and hydraulic oil.

Abstract

The invention relates to the technical field of engineering construction, in particular to a shock isolation device applied to a tunnel, and the shock isolation device is arranged on the periphery of the tunnel. The shock isolation device comprises a plurality of side shock isolation units and an upper shock isolation unit, one side shock isolation unit comprises a first side plate tightly attached to the outer side wall of the tunnel, the first side plate is vertically arranged on the outer side wall of the tunnel, a second side plate is arranged on the side, away from the tunnel, of the first side plate, and the first side plate and the second side plate are horizontally arranged; a gap exists between the first side plate and the second side plate, a storage box is vertically arranged in the gap, a first interval exists between the storage box and the first side plate, a second interval exists between the storage box and the second side plate, and connecting strips for connecting the storage box are arranged on the first interval and the second interval respectively. A water flow channel is formed between every two adjacent connecting strips. It is guaranteed that the filler in the storage box is not affected by downward seepage water, and then the shock insulation effect is guaranteed.
