我们继330复线工程中的三座高桥墩采用滑模施工后,自去年7月份以来又在上三线十五合同段的高桥墩施工中采用滑模施工工艺。 上三线十五合同段内有四座高架桥,桥墩净跨均为40m,最高桥墩42.95m(龙坑大桥5#墩),系上三线全线最高桥墩。 滑模工艺主要由滑动模板和提升系统两部分组成。滑动模板由模板、围圈、支承杆(爬杆)、提升架、 Following the slipform construction of the three high-bridge piers in the 330 double-track project, we have adopted the slip-form construction technique since July last year in the construction of high piers of the upper third-fifteenth contract. There are four viaducts in the third and fifth contracts, with a net span of 40m and a maximum pier of 42.95m (Pier # 5 of Longkeng Bridge), with the highest piers across the three lines. Sliding mode is mainly composed of sliding template and lifting system. Sliding template from the template, the circle, the support rod (climbing pole), lifting frame,
