混凝土泵是一种能一次连续完成混凝土水平和垂直运输的施工设备。具有施工效率高、减轻劳动强度、降低成本费用等特点。因此,泵送混凝土工艺越来越多地在建筑施工单位得到应用。本文就混凝土泵因操作使用不当、维护保养不力等,引起的一些故障,探讨故障原因和对策。1 操作使用方面1.1 混凝土塌落度的选择 泵送混凝土的塌落度根据可泵性要求应严格控制,以保证泵送效率高、不阻塞、混凝土泵机件的磨损小等。混凝土塌落度过小,泵送时吸入混凝土缸较困难,使得充填效率小,影
Concrete pump is a kind of construction equipment that can complete the horizontal and vertical transportation of concrete at one time. With the construction of high efficiency, reduce labor intensity, reduce costs and other characteristics. Therefore, pumping concrete technology is increasingly used in construction units. In this paper, some failures caused by improper use of the concrete pump due to improper operation and maintenance are discussed, and the cause of the failure and the countermeasures are discussed. 1 Operation and use aspects 1.1 Selection of concrete slump degree The slump of pumped concrete should be strictly controlled according to the pumpability requirements to ensure high pumping efficiency, non-blocking, and small wear of concrete pump parts. When the concrete slump is too small, it is difficult to inhale the concrete cylinder while pumping, making the filling efficiency small.
