Space centering method for embedded guide pipes at two ends of stay cable of cable-stayed bridge

The invention relates to a space centering method for embedded guide pipes at the two ends of a cable-stayed bridge cable. The method comprises the following steps that a bridge tower cable guide pipe centering detection receiving device array (2) and a main beam cable guide pipe centering detection transmitting device array (5) are installed; roughly adjusting the pre-embedded guide pipe; finely adjusting the position of the pre-embedded guide pipe; checking the inclination angle position of the pre-embedded guide pipe; and the distance between the corresponding point positions of the transmitting device and the receiving device is measured again, and the spatial position of the pre-embedded guide pipe along the axis is adjusted. According to the method, the possibility of realizing the space centering state of the pre-embedded guide pipes at the two ends of the cable-stayed bridge cable is effectively improved, and the method can be used for guiding actual engineering of space centering construction of the
