the construction method of the ordinary cemented soil stiffness core composite pile is that the pile peripheral cemented soil and the core pile are constructed at different time, which might lead to the situations as the pile body is broken due to the forced inserting of the core pile into the cemented soil mixed pile after the initial setting time, the neighboring finished pile is damaged due to the compacting effect caused by the reaming construction of the core pile and the failure of effectively transferring the load due to the loose joining of stiffness core pile and the cemented soil whose construction is completed after the initial setting time. This paper aims to overcome the defects of the conventional construction method by introducing a new construction technology, and the construction technology is verified to be reliable through the application in the actual engineering projects and has the advantages that the peripheral soil body is significantly strengthened, the composite pile foundation can effectively overcome the harm as uneven settlement of buildings, so as to ensure the normal usage of the buildings, and the construction technology has excellent economic benefits and is significant for the later construction technology for treating the soft soil foundation. |
