Research on Structure and Control Method of Segment Erector Based on Tunneling-Erecting Synchronous Shield Machine
Aiming at the characteristics of the additional tunneling time for the segment erection caused in the axial insertion segment erection by the tunneling-erecting synchronous shield tunneling machine,the adaptation of segment erector is analyzed.By comparing various segment erector schemes,a scheme not to change the traditional large translation to erect the main structure is ultimately adopted.The erection system has a dual mode of following and compensation through algorithms and control,which can keep the erector stationary with the shield machine and tunnel respectively.Aiming at the working condition of segment erection by this shield machine,the reliability of translating the beam by the segment erector is analyzed,which can meet the requirements of synchronized shield tunneling and segment erecting.
