- Abstract:
- Taking the intake pipe collapse disposal in an urban underpass stormwater pumping station of Hangzhou as an example, this paper analyzes the causes of pipe collapse, puts forward the semi-excavated artificial shield casing technology creatively and elaborates the process of composite PC steel pipe pile construction, pipe shed grouting reinforcement，artificial shield tunneling, steel casing installation, new pipe jacking, CIPP lining, etc. Plaxis finite element analysis software was used to establish the structural models of U-shaped groove, pump house, steel sheet pile and pipe shed, etc., to simulate the construction process of semi-excavated artificial shield tunneling. Combined with the dynamic whole-process monitoring data of construction, it was proved that the technology was safe and reliable, which could be used for reference in similar projects.
