The technology belongs to the foundation engineering field and is applicable to the foundation treatment of the highway and civil engineering under the geological conditions that the upper part is solid thick overburden and the lower part is soft soil.
Engineering geological prospecting shall be carried out to the construction site, so as to get to know the quality and burial condition of the overburden soil layer and the lower soft soil layer and compile the Report on Engineering Geological Prospecting of Construction Site.
Conclusions Through the application and verification of actual engineering projects, compared with the conventional construction technology, the construction technology of rigid-flexible composite piles for thick overburden and deep-buried soft soil has the advantages that the overmuch disturbance on the thick overburden brought by the overburden guide hole is avoided, the problems that the conventional foundation treating measures are insufficient for treating the overburden deep-buried soft soil area are effectively solved, and different materials are adopted to treat, namely, the concrete rigid pile is adopted for reinforcing the soft soil layer with poor soil body quality and the cement mortar is adopted for reinforcing the overburden with excellent soil body quality, therefore not only the reinforcing effect is ensured, but also the construction cost is saved.
