整体浇筑的混凝土和喷射混凝土是地下工程施工中的主要结构材料。高质量地下混凝土和喷射混凝上构筑物只有在使用高效的先进工艺设备时才有可能达到。先进的设备不仅能确保施工的高速度,而且能取得很大的经济效益。例如可节省材料(水泥和骨料),提高模板周转率,大幅度降低骨料灌浆的操作费用。减少或者完全取消建筑物前期和以后运行中的装修或改建的工作量。
Integral poured concrete and shotcrete are the main structural materials in underground construction. High-quality underground concrete and jet coagulation upper structures are only possible when using highly efficient and advanced technological equipment. Advanced equipment can not only ensure the high speed of construction, but also can achieve great economic benefits. For example, materials (cement and aggregate) can be saved, the turnover rate of the template can be increased, and the operation cost of the aggregate grouting can be greatly reduced. Reduce or completely eliminate the amount of work required for renovations or alterations in the pre- and subsequent buildings.
