摘要
讨论了电动振拔沉管灌注桩设计和施工中的问题,认为沉管双控中不少情况下应以沉入度控制为主,建议全部沉管灌注桩都进行动测法检验,并讨论了施工中复打、反插。
This article discusses some problems of vibro-pulling sink-pipeline pile powered by electricity.We think majority of vibro-pulling sink-pipeline piles powered by electricity should be controlled by settlementspeed.We propose all the piles must be tested by a dynamic survey method.And we also discuss repeat-sink pipeline,sinking pipeline in the opposite direction,breaking of head of piles,a full coefficient of concrete and so on under construction.
