Method for detecting height of slurry surface inside grouting sleeve by using standard thickness weight

The invention provides a method for detecting the height of the slurry surface inside a grouting sleeve by using a standard thickness weight, wherein the method uses a device for detection. The devicecomprises standard weights (1), a connecting line (2), and a weight tube (3). To be specific, the method comprises: connecting the connecting line (2) to one standard weight (1)fixedly and to other weights in series, arranging the connection part at the front end of the weight tube (3), and holding a connecting end or connecting the connecting end fixedly by a fixed support device and leading theweights out of a to-be-detected grouting sleeve though a slurry outlet hole till exceeding the slurry outlet hole of the sleeve by the weights, and indicating the unfilling height of the grouting sleeve according to the led weight thickness sum and a scale displayed by a last weight. The method is accurate and simple and is easy to operate. 本发明提供了一种应用标准厚度砝码检测灌浆套筒内浆面高度的方法，使用以下装置进行检测，所述装置包括标准砝码（1）、连接线（2）和砝码导管（3）；所述检测的具体步骤包括
