The concrete pipe is a pipe made of concrete or reinforced concrete and used for conveying fluids such as water, oil, gas and the like. Concrete pipes are classified into plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. According to the different inner diameters of concrete pipes, the concrete pipes can be divided into small-diameter pipes (with the inner diameter below 400 mm), medium-diameter pipes (400-1400 mm) and large-diameter pipes (with the inner diameter above 1400 mm). The pressure pipe can be divided into low pressure pipe and pressure pipe according to the difference of the water pressure bearing capacity of the pipe, and the working pressure of the pressure pipe is generally 0.4, 0.6, 0.8, 1.0, 1.2 MPa and the like. Concrete pipes are classified into plain pipes, spigot-and-socket pipes, and tongue-and-groove pipes, depending on the type of pipe joint. The joint forms comprise a cement mortar smearing joint, a steel wire mesh cement mortar smearing joint, cement mortar socket joints, rubber ring socket joints and the like.

In the in-process of the water of impurity such as the transportation has more silt, silt is deposit in the pipeline easily, cause concrete pipe to block up, among the prior art, often behind the pipe blockage, need artifical investigation, confirm the jam point, then go on leading to stifled maintenance, on the one hand, just can discover behind the jam, be difficult to carry out the early warning before blockking up, lead to leading to the degree of difficulty grow of stifled and maintenance, on the other hand, artifical investigation behind the jam, work load is great, the work load that leads to whole maintenance is great, efficiency is lower, still cause easily to lead to the untimely condition of stifled.
