Research On The Application Of Small Diameter Bored Injection Pile In Foundation Consolidation

In this paper, research on the application of small diameter bored injection pile in foundation consolidation was involved.Based on reading documents of the application of small diameter bored injection pile in foundation consolidation, design principles and calculate methods of small diameter bored injection pile in foundation consolidation were introduced and analyzed in this paper.Function mechanism, work characteristic and range of application and so forth of consolidation design with applying different frame forms which contain odd packet, net frame and so on were expatiated. Idiographic construction methods of small diameter bored injection pile and disposal of existing problems in constuction were also be discussed, in order to meet technique requests of groundsill stabilization, resisting float and sedimentation control and so on and meet the purpose of project consolidation.By analyzing examples of project consolidation such as culvert of excluding waterlogging, choise priciples and calculation methods of groundsill consolidation were discussed, depending on idiographic characteristic of different projects and combining conditions of geology> environment etc, effects of consolidation were also be evaluated in this paper. Project practice indicates that application of small diameter bored injection pile in foundation consolidation is an effective management.Technique characteristics of application of small diameter bored injection pile in foundation consolidation were summarized at the last of the paper, and problems which should be discussed forward were also be given.
