钢纤维掺量需要注意的事项都有哪些？
钢纤维掺量检验:硅铸造现场抽样检验钢纤维含量，至少两次每班检查工作，每组三个样本，每个样本1ol。通过水洗试验，将水洗后的纤维从硅中烘干、称重，单次取样的纤维含量偏差，比之第20%卷，每样高于平均纤维含量的三个样品的偏差不得超过5%的剂量比例。
Steel fiber content test: Silicon casting spot sampling inspection of steel fiber content, at least twice per shift inspection work, each group of three samples, each sample 1 ol. Through the washing test, the fibers were dried and weighed from silicon, and the deviation of fibre content in single sample was no more than 5% of the dose ratio of three samples higher than the average fibre content compared with volume 20.
纤维表面的硅钢纤维湿保养：不少于7d，时间越长越好，用湿袋铺在表面或维修材料。光纤传输梁的维护，避免接触风和日晒、雨淋、处理施工梁体密封处理等。在达到具体规格后，应严格控制拆除时间。如果工程在冬季施工的强度，可以按照传统的方式采取防冻措施。纤维长度、钢纤维直径(直径)和长径比对纤维增强效果的影响。长细比增强纤维。纤维长度太短，增强时间过长，施工难度较大，影响混合料质量，小直径弯折过程中混折，在同体积比下粗化，增强效果差。
Wet Maintenance of Silicon Steel Fiber on Fiber Surface: Not less than 7 days, the longer the better, use wet bag to spread on the surface or repair materials. Maintenance of optical fiber transmission beams to avoid exposure to wind and sunshine, rain, and sealing treatment of construction beams. After reaching the specific specifications, the demolition time should be strictly controlled. If the strength of the project is in winter, the anti-freezing measures can be taken in accordance with the traditional way. The effect of fiber length, diameter (diameter) and aspect ratio of steel fibers on fiber reinforcement. Slenderness ratio reinforcing fibers. The length of fibers is too short, the reinforcing time is too long, and the construction is difficult, which affects the quality of mixtures. The small diameter bending process is mixed and coarsened under the same volume ratio, and the reinforcing effect is poor.
由于钢纤维抗拉强度高、抗剪强度高、围岩变形和土体承载力大、整体性能好，可用于工程边坡的工程支护。在开化县，浙江省西压力隧洞水电站通过光纤注入围岩衬砌工程期间，可以在较大程度上发挥作用，衬砌厚度从原来的减少钢筋混凝土衬砌厚度500mm纤维喷射混凝土衬砌厚度60mm，消除钢加工的需要和工程量结合，同时无需模板及回填灌浆，成本每米1175元至398元，减少3 / 4的工作量。建设项目正常运行。
Because of its high tensile strength, high shear strength, large deformation of surrounding rock, large bearing capacity of soil and good overall performance, steel fiber can be used for engineering slope wufangbu.07858.netxinban.07858.netlalijii.07858.netshiyanji.07858.netliuhuaji.07858.net liuhuajii.07858.netsupport. In Kaihua County, the West Pressure Tunnel Hydropower Station of Zhejiang Province can play a role to a large extent during the lining project of surrounding rock injected by optical fibers. The lining thickness can be reduced from 500 mm of reinforced concrete lining thickness to 60 mm of fiber shotcrete lining thickness, eliminating the need of steel processing and combining engineering quantity, and without formwork and backfilling grouting, the cost can be reduced from 1175 yuan to 398 yuan per meter. 3/4 less workload. The construction project runs normally.
