Drainage Pipe Retaining Shield and Improvement

摘要：

　　Through research on drainage pipe retaining shield buried by mud and sand, a new improved method of vibrational lift is raised and the hydraulic system design of vibrational excitation is given.Research results show that imposing periodic vibration to sand around the retaining shield can greatly reduce the resistance of mud and sand so the retaining shield can be lifted out of the mud and sand easily.
