The invention provides a method for detecting the grout surface height of a grouting sleeve by establishing a standard curve. The method comprises steps that firstly, a relation curve between the downward height change of the grouting sleeve from a water surface of a grout outlet hole and the corresponding water amount is established; secondly, the water is injected into a to-be-detected standardsleeve, the water injection amount and the water injection loss amount are solved, and the actual water injection amount is obtained; thirdly, according to the actual water injection amount, a water injection height value can be found from a standard curve or a standard table, that is, a height deviation value that a grouting slurry surface in the grouting sleeve is not full or cannot meet the design requirement of the grouting slurry surface due to construction reasons can be obtained. The method is simple, effective, accurate and easy to operate. 本发明提供了一种建立标准曲线对灌浆套筒浆面高度的检测方法，该方法先建立灌浆套筒从出浆孔水面向下高度变化与对应盛水量的关系曲线，然后往待检测的
