Construction Technology of Consolidation for Collapsible Soil at Pipe End of Pre-stressed Pipe Pile by High-pressure Rotary Jet Pile

Abstract:

The paper introduced the construction technology of consolidation for collapsible soil at pipe end of pre-stressed pipe pile by high-pressure rotary jet pile with an engineering case. When the subsidence of the pile end of pre-stressed pipe pile occurred in bearing stratum of collapsible soil with many restricted conditions for consolidation, the pertinent construction operations, technical processes, technical parameters and the countermeasures were adopted.
