在提倡节能环保的今天,制砂制石成套设备的应用和推广,将对建筑垃圾资源的再生和砂石骨料的生产产生全新且积极的影响。随着城市化进程的发展,房屋拆迁和市政动迁工程增加,我国每年会产生大量的建筑垃圾。建筑垃圾以废旧钢筋混凝土和砖木等为主,占用大量土地,若处理不当,不仅会对环境造成破坏,同时也将造成土地资源的浪费。我国现有建筑物平均寿命只有25~30年,有人预测,未来20年,我国的建筑垃圾增长会进入高峰期。
In advocating energy saving and environmental protection, the application and popularization of sand making equipment will have a new and positive impact on the regeneration of construction waste resources and the production of gravel aggregate. With the development of the urbanization process, the demolition of houses and the relocation of municipal projects have increased, and a large amount of construction rubbish will be produced each year in our country. Construction rubbish mainly uses waste reinforced concrete, brick and wood and occupies a large amount of land. If handled improperly, it will not only cause damage to the environment but also cause waste of land resources. The average life expectancy of existing buildings in our country is only 25-30 years. Some people predict that in the next 20 years, the growth of China’s construction rubbish will enter a peak period.
