Cast-in-situ bored pile underwater concrete spouting and vibration construction method and device
The invention provides a cast-in-situ bored pile underwater concrete spouting and vibration construction method and device, and relates to the technical field of underwater concrete spouting. The cast-in-situ bored pile underwater concrete vibration construction method comprises the following steps that concrete is spouted from the bottom of a pile hole to the position which is higher than an piletop design elevation by 0.8-1.0m or above by adopting a tremie method, so as to form a vibration-free underwater concrete pile body; after a tremie outside the pile hole is inserted into the vibration-free underwater concrete pile body, a vibrating device is used for carrying out first retained vibration, the tremie is lifted after the first retained vibration, then the vibrating device is used for carrying out second retained vibration, the tremie is downward reversely inserted after the second retained vibration, then the vibration device is used for third retained vibration, and the secondretained vibration and the third retained vibration are repeated until the tremie is lifted out of the top surface of the vibration-free underwater concrete pile body. According to the construction method, underwater spouted cast-in-situ bored pile concrete is effectively vibrated, and the compactness of pile body concrete is improved.
本发明提供了一种钻孔灌注桩水下混凝土灌注振捣的施工方法和装置，涉及水下混凝土灌注技术领域。本发明提供的钻孔灌注桩水下混凝土振捣的施工方法，包括以下步骤：采用导管法将混凝土由桩孔底灌注至桩顶设计标高以上0.8～1.0m，形成未振捣的水下混凝土桩身；将桩孔外的导管插入至所述未振捣的水下混凝土桩身后利用振捣装置进行第一留振，所述第一留振后将导管提升后利用振捣装置进行第二留振，所述第二留振后将导管向下反插后利用振捣装置第三留振，重复所述第二留振和第三留振至导管提出所述未振捣的水下混凝土桩身顶面。本发明提供的施工方法对水下灌注的钻孔灌注桩混凝土进行有效振捣，提高了桩身混凝土的密实度。
