Open caisson sinking assisting device, open caisson structure and control method
The invention provides an open caisson auxiliary sinking device, an open caisson structure and a control method, and belongs to the technical field of open caisson structures. The sinking assisting device for the open caisson comprises a high-pressure rotary spraying system, the high-pressure rotary spraying system comprises a plurality of spray head sets arranged on the blade pedal face of the open caisson, the spray head sets correspond to all areas of the blade pedal face, each spray head set comprises a plurality of rotary spray heads, and each rotary spray head is used for spraying water flow in the horizontal direction and the vertical direction; the rotary spray head can rotate around the vertical shaft; the open caisson posture detector is used for detecting the posture of the open caisson and obtaining corresponding posture parameters; the plurality of bearing capacity sensors are used for detecting the foundation bearing capacity of the foundation facing each area of the blade pedal surface; wherein the rotating nozzles of each nozzle group work according to the attitude parameters, the water pressure determined by each foundation bearing capacity and the nozzle rotating speed. According to the open caisson sinking assisting device, the ground breaking efficiency can be improved, the open caisson posture is adjusted, and active sinking is achieved.
本发明提供了一种沉井助沉装置、沉井结构及控制方法，属于沉井结构技术领域。沉井助沉装置包括：高压旋喷系统，高压旋喷系统包括多个设置于沉井的刃脚踏面处的喷头组，各个喷头组对应于刃脚踏面的各个区域，喷头组包括多个旋转喷头，每一旋转喷头用于沿水平方向和竖直方向喷射水流，且旋转喷头可绕竖直轴旋转；沉井姿态检测器，用于检测沉井的姿态并得出相应的姿态参数；多个承载力传感器，用于分别检测刃脚踏面的各个区域所面对的地基的地基承载力；其中，各个喷头组的旋转喷头以根据姿态参数、各个地基承载力所确定的水压和喷头旋转速度工作。本发明的沉井助沉装置能够提高破土效率，调整沉井姿态，实现主动下沉。
