发展机遇今年国家加大投资,民间资本进入,我国铁路公路等各项基础设施建设全面提速。而地铁即城市轨道交通建设项目,也即将在近期开启新一轮快速推进的建设大幕,为基建领域添上浓墨重彩的一笔。城市地铁的建设离不开砂石骨料,优质的砂石资源是保障工程进度和安全的重要前提。随着各地地铁项目的陆续开工,这就意味着对砂石骨料的需求量也是日趋增大。为了保障砂石的供给,大型的制砂生产线和混凝土搅拌站都需要跟随地铁线建设,这为砂石产业与相关设备制造商创造了巨大 Opportunities for Development This year, the state increased investment, private capital entered the country, and all railway infrastructure projects in China were speeding up. The metro, that is, urban rail transit construction projects, will also soon open a new round of rapid construction of the curtain, adding a solid foundation for infrastructure. The construction of urban subway can not be separated from the gravel aggregate, high-quality gravel resources is an important prerequisite to protect the progress and safety of the project. With the succession of subway projects around the start, which means that the demand for gravel aggregate is also increasing. In order to ensure the supply of sand and gravel, large-scale sand production line and concrete mixing station need to follow the subway line construction, which has created a huge market for sand and gravel industry and related equipment manufacturers
