液压混凝土泵的泵送能力强、工效高、故障少,维修也比较简单。但是由于运行人员对泵的性能不太熟悉,加之施工管理不善,浇筑中也常出现堵管现象。更严重的是,堵管本来不难排除,但往往因为处理不善,致使施工中断,造成人力、物力的浪费,工期延误,混凝土质量也大受影响。我局最近在浇筑施工中就出现过这种情况,应引起足够的重视。现就如何进行泵送施工、预防堵管提出一些看法,供参考。一、施工前的准备施工准备的完好程度是浇筑能否成功的基础。诸如泵是否处于良好状态,管路是否合乎要求,砂石、骨料和水泥是否按规格备好,风、水和电能否保证,所有现场施工 The hydraulic concrete pump has strong pumping ability, high work efficiency, fewer failures, and relatively simple maintenance. However, due to the operator’s unfamiliarity with the performance of the pump, coupled with poor construction management, plugging often occurs during pouring. What is more serious is that it is not difficult to eliminate the blockage of the pipe, but often due to poor handling, construction is interrupted, human and material resources are wasted, construction period is delayed, and concrete quality is also greatly affected. This situation has recently occurred in the construction of the cast-in-place in our bureau and should be given sufficient attention. Here are some suggestions on how to carry out pump construction and prevent blockage for reference. I. Preparation before construction The degree of completion of construction preparation is the basis for the success of pouring. Such as whether the pump is in good condition, whether the pipeline meets the requirements, whether sand, aggregate and cement are prepared according to specifications, wind, water, and electricity are not guaranteed, and all on-site construction
