Abstract

The invention relates to the technical field of bridge erecting, in particular to a method for erecting a beam at a tunnel entrance. According to the method for erecting the beam at the tunnel entrance, during beam erecting, the height of a beam transporting main beam can be adjusted, then bridge erecting work is completed through cooperation of a beam guiding machine and a beam transporting machine, beam erecting work of the tunnel entrance can be completed rapidly through the method, the beam transporting machine does not need to be replaced, the bridge erecting cost is lowered, and the bridge erecting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge erection, in particular to a method for erecting beams at tunnel entrances. Background technique [0002] The integrated frame transporter can be used for hoisting and transporting concrete box girders of passenger dedicated lines in concrete beam yards, and can erect concrete box girders at bridge positions. The existing all-in-one machine for transporting frames mainly includes two parts: a beam transporting machine and a beam guiding machine. The beam transporting machine can also lift and transport the guiding beam machine to transfer the construction site, and can also lift concrete box girders through the double-lane tunnel of the passenger dedicated line. [0003] Compared with the traditional frame transport equipment, the frame transport integrated machine has fast construction speed and flexible maneuverability, which can realize zero-distance bridge erection at the tunnel entrance, and b...
