Dynamic Response Analysis of Buried Drainage Pipes for Polymer Grouting Trenchless Rehabilitation under the Traveling Wave Effect

Figure 10

Time course curve of transverse vibration displacement of pipes at different positions. (a) Wave speed  = 100 m/s (normal). (b) Wave speed  = 200 m/s (vacant). (c) Wave speed  = 500 m/s (polymer grouting repair).
