Multi-channel drill rod with monitoring function
The invention provides a multi-channel drill rod with a monitoring function. The multi-channel drill rod comprises a drill rod body, a built-in pipeline and an inclination measuring device, wherein the drill rod body is provided with a male connector, a female connector and an upper guniting opening; a first slurry pipe, a second slurry pipe and an air pipe of the built-in pipeline are arranged in an inner cavity of the drill rod body in the mode that the sections of the first slurry pipe, the second slurry pipe and the air pipe are equilateral triangles, and the axial directions of the first slurry pipe, the second slurry pipe and the air pipe are parallel to one another; the first slurry pipe is connected with the upper guniting opening; the inclination measuring device is fixedly installed on the outer wall of the portion, below the upper guniting opening, of the drill rod body; a sensor is fixedly installed on a plate support; and an external control cable is inserted into the air pipe and then connected with the sensor in the inner cavity of the drill rod body. According to the multi-channel drill rod, the rotation skewness of the drill rod is monitored in real time, an operator is reminded to take measures, the strength of the upper portion and the strength of the lower portion of a pile body of a stirring pile are consistent, and the vertical precision of the pile body of the stirring pile is ensured, and the construction efficiency and the engineering quality are improved.
一种具有监测功能的多通道钻杆，包括具有公接头、母接头和上喷浆口的钻杆体、内置管路和测斜装置；内置管路的第一浆管、第二浆管、气管以其截面为等边三角形、轴向方向互为平行的方式设置在钻杆体内腔，第一浆管连接上喷浆口；测斜装置固装于上喷浆口下方的钻杆体外壁上；传感器固装于板支座上，外部控制线缆插入气管后在钻杆体内腔与传感器连接。本发明实时监测钻杆旋转偏斜度并提示操作者采取措施，保证搅拌桩桩身强度上下一致和垂直精度，提高施工效率和工程质量。
