Application of Retaining Method by Micro-pile Top Connected with Foundation in the Foundation Pit Adjacent to Buildings

Abstract:

For being adjacent to buildings, the retaining is very difficult in narrow foundation space. Based on a foundation pit engineering in Tianjin, this paper introduces a retaining method, by which the micro-pile top is connected with the foundation. The engineering practice shows that the construction is convenient and the horizontal displacement of supporting structure can be effectively controlled to ensure the safety of supporting structure, reduce the influence to the adjacent building and reduce the cost of foundation pit.
