Background

In recent years, the economy of China is rapidly developed, a huge amount of artificial slopes are formed in the construction process of roads, railways, buildings and the like, and slope reinforcement is required to be carried out through anchor cables. When the anchor cable is reinforced, the anchor section of the anchor cable needs to be grouted, and 8.4.4 regulations in the existing technical regulations of rock-soil anchor rods (cables) (CECS 22: 2005): when the hole overflows slurry or the exhaust pipe stops exhausting, grouting can be stopped. But the slurry overflowing from the orifice has certain delay in time, so that the grouting amount is larger than the designed amount; the exhaust stopping method of the exhaust pipe needs to be judged manually and continuously, has certain experience, has large errors, can cause the grouting amount to be inconsistent with the design amount, can cause poor construction quality under the two conditions, and even can not meet the construction technical requirements sometimes. In addition, communication obstacles exist among anchor cable hole grouting constructors, grouting pumps and grouting pipe switch operators, and uncertainty is brought to grouting quality. Meanwhile, the process needs manual participation, the labor intensity of constructors is increased, and some unsafe factors exist. Therefore, an instrument suitable for detecting the liquid level position of the grouting liquid in the anchor cable hole is needed.
