由于铁路行车提速,高速铁路路基的相关附属标准也相应提高,骨架护坡材质由原来的浆砌片石逐步改为浇筑片石混凝土或者混凝土。铁路路基边坡设计坡度通常为1:1~1:1.75,且主骨架两侧有镶嵌预制混凝土挡块,采用骨架护坡导轨翻模式施工方法确保了混凝土的密实度和外表光洁度,同时降低了人力劳动强度,加快了施工进度,确保了结构物的实体质量,取得了显著的经济效益和社会效益。
Due to the speeding up of railway traffic, the relevant subsidiary standards of high-speed railway subgrade are correspondingly increased. The material of skeleton slope protection is gradually changed from the original mortar to the slab concrete or concrete. The slope design of railway roadbed slopes is usually 1: 1 ~ 1: 1.75, and the two sides of the main skeleton are embedded with prefabricated concrete blocks. The use of the skeleton slope guide rail turn-over construction method ensures the compactness and the appearance smoothness of concrete while reducing the manpower Labor intensity, speeding up the construction progress, ensuring the physical quality of structures and achieving significant economic and social benefits.
