The Application of Bored Pile Post Grouting Technology in the Foundation Construction of High-rise Residential Building
As a common form of pile foundation,the bearing capacity and stability of bored piles have an important impact on the safety of high-rise buildings.Considering the complexity of geological conditions and the high requirements for foundation bearing capacity and settlement performance of buildings themselves,the bored pile post grouting technology is adopted to strengthen the bored piles.By accurately controlling the grouting materials and pressure,the bonding degree between the pile body and the surrounding soil is effectively improved,and the overall bearing capacity and stability of the pile foundation are enhanced.The bearing capacity and settlement performance of the test pile PE-01 were tested.The results show that the test pile still maintains good stability when the load reaches 7 000 kN,which meets the design requirements.It is confirmed that the bored pile post grouting technology has a certain application prospect in important engineering such as high-rise residential buildings.
