位于京九铁路赣南段的铁道部深路堑红色粘土岩边坡支护科研项目——挂网喷混凝土框架锚杆挡墙,已由铁十三局四处施工完毕。该墙长125 m,高25 m,号称京九南段第一长大锚杆挡墙。 京九铁路赣南深挖路堑由于受红色粘土岩极易风化崩解的特性影响,边坡稳定性极差。为此铁道部建设司在京九南段设立了红色粘土岩边坡支护新型结构科研项目,采用框架挂网喷 Located in the south of the Beijing-Kowloon Railway section of the Ministry of Railways deep red clay rock slope supporting research project - Hanging net shotcrete anchor bolt retaining wall, has been completed by the iron 13 Bureau of four construction. The wall is 125 m long and 25 m high. It is known as the first large anchor retaining wall in the southern section of Beijing-Kowloon. Due to the extremely easy to weathering and disintegration characteristics of red clay rocks, the stability of the side slope is extremely poor. To this end, the Ministry of Railways Construction Department has set up a new type of scientific research project of red clay rock slope support in Beijing-Kowloon section.
