Background
In recent years, due to the advantages of convenient construction, small pollution to conveyed substances, low engineering cost and the like, the plastic pipeline is widely applied to the construction of domestic underground pipe networks, and particularly has the widest application in pipelines for conveying fuel gas and tap water. Because of the characteristics of non-conduction, non-magnetic conduction and lower strength than the metal pipe of the plastic pipeline, the detection line or the sacrificial anode wire is buried on the plastic pipeline simultaneously when the pipeline is laid for detection and protection of the buried pipe network, and the position of the pipeline is detected by utilizing the characteristic of electromagnetic field generated by the conduction of the detection line. However, the cables are buried all the time, and how to apply an electric signal from underground to ground for detection is a technical problem.
Meanwhile, if a plastic pipe is not used as a transport carrier, a metal pipe is generally used. In the buried state, a sacrificial anode is necessary to reduce the galvanic corrosion. Sacrificial anodes also present the need to run several cables from underground from a buried pipe network.
At present, the main method for leading out the detection line or the sacrificial anode line is to construct a valve well, but only the detection line is operated and the detection function is adopted, and an inspection well is specially arranged, so that the economic investment is large, and the cost is more than two thousand yuan. Secondly, the method aiming at the soft foundation ground is mainly used for building a valve well.
Equivalently, another approach to the current extraction of sacrificial anode wires or test lines is to add special test piles. However, the cost is too high by adopting the special detection pile for the operation and detection of the thread end of the sacrificial anode, and the special detection pile can only meet the condition of a soft foundation pavement, so that the construction on a cement pavement cannot be realized.
Thirdly, a detection wire box is required to be independently arranged on the wall of the valve well and the wall surface of the extraction vertical pipe or the extraction of the sacrificial anode wire.
In this way, the problems of various patterns and low economical efficiency are caused by the extraction of the underground pipe network detection line, and the detection of the underground pipe network is extremely unfavorable.
