On July 16th, with the person in charge of the rail transit group, it was announced loudly that it was undertaken by the China Railway Ten Bureau and a total length of 30 meters. The pre -production box beams were successfully completed, marking the construction stage of the project to fully enter the upper structure of the bridge, laying a solid foundation for the realization of the annual opening goal at the end of the year, and the horn of the follow -up construction of the subsequent construction.

At the construction site, relevant personnel such as testing, security, and technical personnel supervised each station before each process. "We arrange special personnel, monitor the data in real time, strengthen the control, and ensure that the first beams are stable and stable. The entire lifting and erection process is orderly." According to Lu Jiping, chief engineer of the Yantai Express Road Project of China Railway Ten Bureau The pre -production box beam is transported by a dedicated beam truck. The two 200 -ton crane cranes are installed by dual -machine lifting cranes. Two cranes slowly lifted the box beams and lift off. When the rising height of the box beam exceeds the bridge (bridge pier) covering the beam surface, turn the lift box beams into the installation area through the side of the crane, and the crawler is transferred to the installation area. The hanging arm operation of the hanging can accurately enter the position, and finally realize the simultaneous improvement, synchronous steering, and synchronous falling beam of hanging.

"Since the official construction of December 26 last year, the project participating in the construction of the project has been closely collaborated to accelerate the construction of the project. At present, a total of 623 pile foundations have been completed, 160 inheritance of Taiwan, 153 pier pillars, and 665 prefabricated small box beams. , Cover the beams 43. In the next step, we will steadily advance the progress of the beams and have the condition of the beams. We will gradually block the roads and complete the beam as soon as possible to restore the traffic. At the same time Promoting various tasks of warranty and strive to open to traffic at the end of the year, "said Yan Naiqi, director of the engineering department of the Municipal Rail Transit Corporation.
