A new geometry management system for the erection of the concrete pylon of long span bridges is developed and proposed by improving former systems. The so-called integrated geometry management and wireless control system is an automated system, which controls wirelessly the GPS and tiltmeters installed in the same vertical than that the form system so as to manage the geometry and, enables the field workers to control conveniently and remotely the operation of the hydraulic jacks for the motion of the forms using the acquired data. This study verifies experimentally several types of GPS systems in order to assess their applicability during the erection. In addition, the software for the integrated management is developed, and the design and verification test of the wireless control module is also conducted. This system will be of valuable help for the improvement of the constructability, safety and comfort during construction after the completion of the development and experimental verification of the sensing system and integrated program through future complementary studies. |
