CHEN Taizhen ZHAO Xinlong YANG Fan

China Railway No.3 Engineering Group Co.，Ltd.， Taiyuan， Shanxi Province， O3oooo China Abstract： With the increase of urban deep excavation projects，the impact ofconstruction noise on surrounding residents is increasinglysignificant.Taking XiaoheshanstationprojectofHangzhou MetroLine12asthebackground，anoise reduction technology integratingasound sreensystemandacanopysystem is proposed toaddresstheconstruction noise problemof deep foundation pitsadjacent to buildings.Thetechnologycan effectivelyabsorb and block noise through the rapid instalation of columns and sound barier units，the opening design of sound-absorbing nets，and astable anchoring structure，while balancing construction eficiency and flexibility.The practical application shows that the technology significantly reduces the construction noise intensity，reduces dustpolution，and solves the problems of insufcient protectionandobstructionofconstruction in traditional soundproofenclosures，which providesareference solution for similar projects.
