Method for judging blockage of pumped concrete
The invention relates to the technical field of pumping concrete pouring, in particular to a method for judging blockage of pumping concrete, which comprises the following steps: acquiring strain values, temperature and audio data of measuring points and current time, and calculating strain values caused by the temperature and the time by using the current time and the temperature; the strain value caused by temperature and time is subtracted from the strain value of the measuring point to obtain an accurate strain value corresponding to the pipeline pressure, and then a preset acoustic spectrum is compared with the collected audio data to judge whether the concrete at the measuring point flows or not; and when the concrete at the measuring point does not flow and the strain value corresponding to the pipeline pressure at the measuring point continuously increases, the measuring point is blocked by the concrete, so that the problem of time and labor waste in existing pipe blocking judgment is solved, and the method is suitable for judging whether the pumped concrete is blocked or not.
本发明判断泵送混凝土堵塞的方法，涉及泵送混凝土浇筑技术领域，通过采集测量点的应变值、温度和音频数据以及当前时间，利用当前时间和温度计算出由温度和时间引起的应变值，并用测量点的应变值减去由温度和时间引起的应变值获得精确的管道压力对应的应变值，再利用预置的声学频谱与采集的音频数据进行比对，判断出测量点的混凝土是否流动，当测量点的混凝土没有流动且测量点的管道压力对应的应变值持续增大时，则测量点发生混凝土堵塞，解决了现有的判断堵管费时费劲的问题，本发明适用于判断泵送混凝土是否发生堵塞。
