Main application:
Monitoring of over-casting of concrete at the top of cast-in-situ bored pile.

System advantages:
1.Simple principle with novel method and wide application range: determine the filling surface of concrete through the measurement of probe rod force and angle change by directly use the characteristics of high density and hardness of concrete. The principle is simple and reliable and can be apply to all types of situations; 
2.High sensitivity and repeated verification, the result is accurate and reliable: the slight change of force and inclination can be determined through the reaching and recovering of probe rod again and again to ensure the accuracy and reliability of the test results;
3.Automatic determination of concrete location and automatic alarming of sound and light, the operation is intelligent and simple: with the function of one-touch operation of the whole system as well as automatic judgment and automatic alarming of sound and light, it is suitable for all workers;
4.The test results are recorded, and the original test data curve can be checked to verify the test results and ensure that everything is all right.
5.The device is lightweight and durable: the whole equipment has low power consumption, and the power supply can continuously work for 48 hours. The working temperature can reach -20 ºC to 50 ºC. With armoured special cable, it can adapt to the harsh site environment.
