Abstract:
With the rapid development of China’s social economy, infrastructure and transportation resources are increasingly scarce. In order to meet the needs of high-speed development of transportation, highway and bridge construction also need to be accelerated. In the construction of Bridges, how to improve the quality and efficiency of bridge construction, reduce the impact on the surrounding traffic, to ensure the safety of construction personnel is particularly important. Bridge across river and sea can greatly adapt to the traffic demand, bridge construction generally adopts the full support and push construction of these two ways. Among them, the jacking construction is widely used because of its strong adaptability, high precision, fast working efficiency and economic suitability.
随着我国社会经济高速发展,基建交通资源日益紧缺,为了适应高速发展的交通需求,公路桥梁也随之需要加快建设。在桥梁的建设中,如何提高桥梁施工的品质、效率、减少对周围交通的影响、保障施工人员的施工安全尤为重要。跨江跨海大桥能够大大地适应交通需求,桥梁在施工中一般采用满堂支架和顶推施工这两种方式。其中,顶推施工因其适应性强,精度高,工作效率快,经济适宜受到广泛地应用。
