Abstract

A detecting pipeline and controlling process of pipeline seam detecting system relates to the detecting pipeline of pipeline seam detecting system and the control scheme of the detecting pipeline. The technical scheme essentially is that a centralization of control of water and gas is arranged and the controlling process is provided. The invention designed according to the property of preset pipeline and with the combination with concrete structure of sealing ring can be operated automatically or by hand with episodic functions of inflatable seal, absorbing wetness, adding water, detecting and resetting, and realize the functions. The automatic program control and data detecting can be realized by the programmable controller in the controlling cabinet, main outer control, course displaying, data recording or the like is realized by monitoring configure software in the computer with synchronous displaying of data and state and the real-time recording of the process curve of data changes accurately and reliably. The whole control process is executed by the automatic part of the controller order pipeline.

Description

technical field [0001] The invention relates to a detection pipeline of a pipeline seam detection system, and also relates to a control scheme of the detection pipeline. Background technique [0002] With the development of my country's modern urbanization and technological progress, the sewage pipes of large-scale sewage treatment projects all adopt the pipe jacking method. And the specifications will be bigger and bigger, and the quantity will be more and more. At present, my country's existing codes and standards do not have detailed and clear detection methods and technical standards for large-scale pipe jacking. The quality of the sealing performance of the pipe jacking interface is an important symbol to measure the quality of pipe jacking construction. Therefore, how to accurately measure the leakage of the pipe jacking at or near the working pressure, and then combine various unfavorable factors to determine a limit value as a qualified standard to judge whether th...
