The necessity of dredging and testing the drainage network. The sewage network is a systematic network, and when there are doubts or damages in a certain area, it will form a chain reaction that affects the drainage capacity of the entire system. In order to maximize drainage capacity and extend the service life of pipelines, it is necessary to establish * pipeline inspection and evaluation methods and scientific maintenance techniques for regular inspection, evaluation, dredging, and correction.

Sealing is based on the actual pipeline situation and the intensity of water flow inside the pipeline. In order to prevent the water pressure caused by upstream water accumulation after a long sealing time from posing a certain threat to downstream construction personnel, the interval of sealing is determined according to the actual situation. Before sealing, the water inlet of the upstream and intersecting wells should be sealed first. Before sealing, the manhole cover within the construction area should be opened and a protective fence or eye-catching symbol should be placed. Detection instruments should be used to detect the gas in the well to ensure that there is no toxic gas before sealing can be carried out.

Rubber airbags are used to assist in sealing the construction section, which facilitates smooth construction and also helps to prevent drainage issues caused by elevation differences in some well locations, affecting the normal progress of dredging and testing. 5、 Drainage (temporary discharge of sewage pump): After recognizing the blockage of various upstream branches, temporary drainage is carried out to the bottom of the pipeline by about 10 cm and the upstream water level after blockage is controlled. Therefore, the drainage volume of this project is relatively large. 6、 High pressure water jet dredging, transporting quicksand and silt. The high-pressure water jet machine can freely control the high-pressure pipe to operate in the pipeline through the backward and forward water flow generated by high pressure. The high-pressure water flow ejected backward can wash the silt and waste in the pipeline into the inspection well, and then pump them into the silt transport vehicle to be discharged at the address, which can minimize the pollution of silt and waste to the surrounding environment.

We have selected the "Linai" SJ2700 vehicle mounted high-pressure water jet machine imported from the Netherlands for dredging equipment. The vehicle mounted high-pressure water jet machine is suitable for various street operations, not limited by street conditions, not affected by climate, fully mechanical operation, safe and simple. It is equipped with various flushing heads that can be used for various pipe diameters of 200-1000mm. The freely equipped high-pressure pipe can clear pipes with a spacing of about 150 meters, and for some, the pipe jacking technology can be used for long interval sewage pipes. The feature of this device is that the high-pressure water flow can clear blockages caused by mud and various waste materials in the pipeline, except for concrete blocks. It can also remove rust, corrosion, and other attachments on the pipeline wall, reducing the corrosion of the pipeline by acids and alkalis in the sewage.

Pipeline dredging and inspection, sewage pipeline dredging and testing

Municipal sewage pipeline dredging, investigation and rectification pipeline robotEndoscopic testing (providing intuitive and scientific information about the internal conditions of pipelines) can be performed when there is no mud flowing out of the pipeline after initial dredging, and the water level inside the pipeline is not higher than 10 centimeters (in the case of no water). It is necessary for underground workers to wear portable gas exploration instruments, safety belts, gas masks, etc. before going underground for operations. We have chosen the domestic "LD-300 Pipeline Endoscopy System" as the most useful method for pipeline endoscopic detection and evaluation.

The impression generated by the CCTV endoscopic system can be actively saved on the computer's hard drive. Based on the internal conditions of the pipeline, data CDs and written statements can be manufactured for the construction unit and construction party to analyze and evaluate the pipeline situation together. Accurate positioning of damaged or leaking parts can be made, providing scientific and intuitive basis for future repair plans.
