Large-size concrete open caisson sinking process method
The invention relates to a sinking process method of a large-size concrete open caisson, which adopts at least four vibratory hammers to form a vibratory hammer system for multi-point vibration sinking, the vibratory hammers are symmetrically arranged on the upper edge of the wall of the large-size open caisson, and the vibratory hammers are connected with the wall of the large-size open caisson by adopting clamps. And differential vibration of all points is carried out through the vibratory hammer system to carry out large-size open caisson sinking assisting or deviation rectifying. According to the process method, the work efficiency is high, the vibration sinking quality is good, the adopted resonance hammer-free vibration sinking method has extremely small interference on the whole well structure and the surrounding environment, and the problem that the large-size concrete open caisson is difficult to sink and rectify deviation is effectively solved.
本发明涉及一种大尺寸混凝土沉井下沉工艺方法，采用至少四台振动锤组成振动锤系统进行多点振沉，各振动锤对称布置于大尺寸沉井井壁上沿，振动锤与大尺寸沉井井壁采用夹具连接，在大尺寸沉井发生下沉困难或者倾斜时，利用振动锤系统进行各点差异化振动进行大尺寸沉井助沉或纠偏。本发明的工艺方法工效高，振沉质量好，采用的免共振锤振沉方法对沉井结构本身完及周边环境干扰极小，有效解决了大尺寸混凝土沉井下沉与纠偏困难的问题。
