在水利水电整体式钢筋混凝土结构的施工过程中,模板作业是最费劳力的,每浇筑一立米混凝土,其模板作业所耗费的劳力约占总劳力的30～50％。为了减少劳力和节约费用必需寻求一些新的制模材料和新的模板型式来降低模板作业的成本。苏联拜帕津水电站在船闸和泄水建筑物的施工中使用了一种合成材料制成的网式模板。这种网式模板是用直径1毫米的合成纤维织成的,孔眼尺寸为2×2到5×5平方毫米,将其固定在金属支架上,形成网模面。这个工程共使用这种网式模板2.17万平米,效果较好。据分
In the process of construction of integrated water conservancy and hydropower concrete structure, the template work is the most labor-intensive, each pouring a cubic meter of concrete, the template labor-intensive operations of its total labor force accounts for about 30 to 50%. In order to reduce labor and cost savings must seek some new molding materials and new template type to reduce the cost of template operations. The Soviet Union Baqiumin Hydropower Station used a net-shaped form made of synthetic materials for the construction of ship locks and spillway structures. The mesh template is made of synthetic fiber with a diameter of 1 mm and has an eyelet size of 2 × 2 to 5 × 5 mm2, which is fixed to a metal holder to form a mesh die surface. This project uses a total of 21,700 square meters of this network template, the effect is better. According to points
