Survive in the cracks in the hoisting operation of Huanjie in New Taipei City

(Taiwan Business Daily News) the first stage of the New Taipei City Ring Line passes between Xiulangqiao Station and Zhonghe Jing'an Station, about 2.21 km is co-located with Taiwan Line 64 and Jingping Road. In order to maintain the traffic function of Taiwan Line 64 and Jingping Road and not affect the structural safety of the viaduct, the ring viaduct piers can only be set in a 3-meter gap between the east-west lanes of Line 64. What's more, it is necessary to build viaducts above the Taiwan 64 line with a height of more than 20 meters above the ground and two elevated stations, Jingping Station and Jing'an Station. The viaduct project of this section is a standard gap to survive!

Zhao Shaolian, director of transportation of New Taipei City, said that the first stage of the ring line, which is located at the core of the third Ring Line, starts from Xindian Dapinglin Station, through densely populated and built areas such as Xindian, Zhonghe, Banqiao and Xinzhuang, to Xinbei Industrial Park in Xinzhuang District, with a total length of 15.4 kilometers, with a total of 14 stations and a machine factory.

The width of Jingping Road in Zhonghe District is 24 meters, and there is a Taiwan 64-line viaduct above, and the projection area is only about 4 meters on one side. Considering the limited remaining space and prosperous traffic on Jingping Road, the construction tries to avoid the construction of on-site framing and pouring mode. After it is adopted in other "precast" or "prefabricated" bridge structures, it is transported to the construction site for hoisting and assembly using the 3-meter gap between the bridge decks. Save the time of on-site irrigation waiting for solidification, but also shorten the time of road occupation by construction, and effectively reduce traffic impact. "this construction method is like a combination of Lego bricks, one piece at a time," the site construction personnel explained that the cap beam at the top of the pier could not be hoisted with a 3-meter gap because of its large width, so it was necessary to close part of the lane of Xindian to the Banqiao direction at night when the traffic flow of line 64 was relatively slow.
