通过工程实例,阐述了先拱后梁系杆拱桥吊装横梁施工工艺。对其吊装工艺确定、施工流程、操作要点以及取得的效益进行了详细阐述。实践证明,该吊装工艺突破了系杆拱桥传统的吊装方法,为系杆拱桥在横梁吊装施工提供了一个安全可靠、工期短,造价低的先进方法。
Through the engineering example, the construction technology of hoisting beam of the arch arch beam of the back arch beam was expounded. The lifting process is identified, the construction process, operation points and the benefits obtained are described in detail. Practice has proved that the hoisting process has broken through the traditional hoisting method of the tied arch bridge and provided an advanced method for the tied beam hoisting construction of the tied beam to be safe, reliable, short in construction period and low in cost.
