| titleOfInvention | A kind of damping section of jurisdiction for shield driven Metro tunnel |
| abstract | The invention provides a kind of damping section of jurisdiction for shield driven Metro tunnel vibration and noise reducing.Damping section of jurisdiction is made up of section of jurisdiction and damping layer；Damping layer is spary coating type composite damping material.Spary coating type composite damping material is by two components of A, R according to volume ratio 1:0.8‑1:1.2 reactions obtain, and component A is the semi-prepolymer synthesized by 35 60 parts of low degree of functionality polyisocyanates and 50 70 parts of PPGs；Component R includes 15 60 parts of diamine chain stretching agents, 10 75 parts of amine terminated polyethers, 10 70 parts of end hydroxy polyethers, 1 30 parts of intercalated graphite fillers, 1 30 parts of auxiliary agents.Intercalated graphite filler is made up of graphite flake layer and the high molecular polymer between graphite flake layer.The damping layer of damping section of jurisdiction is located at the outside of shield tunnel, improves the distance between damping layer and wheel track to greatest extent, can effectively suppress the generation of ripple mill phenomenon.The present invention will not can impact in the prefabricated completion of section of jurisdiction factory to the duration. |
