Three-dimensional positioning system and three-dimensional positioning method for mechanical open caisson
The invention relates to a three-dimensional positioning system and method for a mechanical open caisson, and the system comprises a gyroscope positioning device which is used as a three-dimensional positioning original point, is installed on the inner wall of the open caisson, and is located on the same plane with a cross beam; the magnetic transmitting device comprises a plurality of magnetic points which are distributed at the measuring points of each segment based on the gyroscope positioning device, and one magnetic point is arranged at the gyroscope positioning device; the magnetic force receiving device is used for being arranged in the open caisson and receiving the magnetic force emitted by each magnetic force point by taking circulating slurry as a magnetic force transmission medium; the positioning sensing device is mounted in the duct piece to sense the relative position of each magnetic point; and the three-dimensional calculation device is used for converting the spatial position of the corresponding measuring point according to the magnetic intensity change of different magnetic points. Slurry generated during tunneling of the stirring and sucking head is used as an electromagnetic transmission medium, three-dimensional positioning of the open caisson in open caisson construction is achieved by means of electromagnetic positioning and a three-dimensional coordinate system, and the requirement for the construction environment is lowered.
本发明涉及一种用于机械化沉井的三维定位系统及三维定位方法，该系统包括：作为三维定位原点的陀螺仪定位装置，安装在沉井的内壁上并与十字梁在同一平面；磁力发射装置，包括基于陀螺仪定位装置布设在每片管片测点处的若干磁力点，其中，有一个磁力点设置在陀螺仪定位装置处；用于设置在沉井内并以循环泥浆作为磁力传输介质接收各磁力点所发射磁力的磁力接收装置；用于安装在管片内部以感知各磁力点相对位置的定位感知装置；用于根据不同磁力点的磁力强度变化换算出对应测点空间位置的三维计算装置。本发明以搅吸头掘进时产生的泥浆为电磁传输介质，借助电磁定位和三维坐标系，实现了在沉井施工中对沉井的三维定位，降低了对施工环境的要求。
