沉管桩因其价格低廉而在住宅建筑中普遍采用，但由于住宅建筑一般紧邻居住区，对施工噪声较为敏感。目前在沉管桩施工过程中为使桩管内砼密实和避免砼粘附于管壁，起管时须开动桩管上端的振源。由于振源位于桩管上端，距桩管下端砼较远，为使振源影响传至下端，需要有较大... Submerged pipe piles are commonly used in residential buildings due to their low price, but are generally sensitive to construction noise due to their close proximity to residential areas. At present, during the process of sinking pile construction, the concrete inside the pile pipe is dense and avoids the adhesion of the concrete to the pipe wall, and the vibration source at the upper end of the pile pipe is to be started when starting up the pipe. Because the vibration source is located at the upper end of the pile pipe, far away from the concrete at the lower end of the pile pipe, it is necessary to have larger ...
