Easy Sight: An Expert in Sewer System Maintenance

As underground pipes have become the blood vessels of a city and local governments spend a lot of manpower and material resources on the construction of sewer pipes, sewer system maintenance is particularly important. When it comes to sewer system maintenance, the question is: what is it? Why we need it? What equipment do we need? This article will give you all the answers to the above questions and recommend some pipeline inspection equipment researched and developed by Easy Sight for you.

1. Why we need maintenance of sewer system?

With the fast development of the national pipeline industry, pipeline safety and its maintenance management have become a topic that is increasingly valued by the national security management department. In recent years, accidents caused by pipeline corrosion have occurred from time to time. Let's imagine what will happen when the pipe damage occurs. The interruption of pipeline operation does affect its work; pipeline leakage will cause environmental pollution, which threatens personal safety and even the whole city; pipe rehabilitation can be difficult, which wastes manpower and material resources, affecting corporate interests. In a word, corrosion and damage to pipelines will bring huge losses.

That is because defects may exist in the stages of pipeline manufacturing, laying and operation. The early and later stages of pipeline operation are the high incidences of accidents, especially in the later period of service, the possibility of pipeline accidents increases sharply. Therefore, we must take measures as soon as possible to minimize the occurrence of accidents, and pipeline inspection equipment can enable us to accurately grasp the operation condition of the pipeline, thereby providing a reliable basis for sewer line maintenance, and timely repairing some serious defects to avoid accidents as much as possible. It can also extend the life of the pipeline. At the same time, the life span of pipelines is prolonged and the interests of the enterprise are also guaranteed. Some analysis results show that detection can reduce sewer line maintenance costs.

2. What is sewer pipe maintenance?

Pipe detecting refers to real-time detection and recording of pipeline deformation, corrosion and other damages, as well as accurate positioning by using pipeline transport media to drive the detector to run in the pipeline. Through pipe locator service, various defects and damages can be found in advance and danger levels of each pipe section can be understood. Furthermore, it can prevent and effectively reduce accidents and save pipeline maintenance funds. an important measure to ensure pipeline safety.

For the first time, a series of preparatory work should be carried out: line measurement and calibration, pig receiving and dispatching ball tube and elbow, oblique opening inspection and transformation; pipeline diameter and deformation inspection, pigging and passing the simulator to confirm. The pipeline meets the requirements for passing the detector. After the implementation, the data shall be processed and a test report shall be made. When necessary, it is necessary to select appropriate pipe sections for excavation verification to determine whether the accuracy and pass rate of pipeline inspection meet the requirements.

3.Pipeline endoscope detection technology for sewage pipe maintenance

As the pipe detecting becomes more important, pipe detection technology is getting more attention. The pipeline endoscope detection technology is widely used, which includes CCTV detection, periscope detection (QV detection) and sonar detection. Easy Sight launched pipeline leak point location detection, which includes various detection methods such as visual, sound, light, and electricity, which truly reflects the condition of the pipeline and outputs visual and quantifiable results. At the same time, it also effectively avoids the problems of traditional methods such as an operator's going down the wells, which may have poor detection effects, high cost, and insecurity. And with pipeline endoscope detection technology, some scientific data will be provided for pipeline maintenance and pipeline rehabilitation.

Here is the detailed information of those three kinds of pipe detecting methods of pipeline endoscope detection technology, which is all adopted by Easy Sight pipe detection equipment.

(1) CCTV detection

CCTV detection, which means closed-circuit television detection, was introduced in the mid-1990s to be applied in the inspection of pipeline internal condition and drainage pipelines. It is currently the most advanced and effective method for pipeline condition inspection in the world. Developed countries such as Europe and the United States have used this method as an effective means for the inspection of drainage pipes, check and acceptance of new drainage pipes. And now, not only for the above usages, but it can also be used in the inspection of the status of the running pipelines (maintenance and repair requirements), the inspection of cleaning and dredging effect, and the inspection before trenchless pipe repair. CCTV detection of pipes adopts an advanced CCTV pipe endoscopic television inspection system, automatically crawling in the pipeline, which detects and photographs the rust layer, scale corrosion, perforation, cracks and other conditions in the pipeline, as well as records the current situation in the pipeline at the same time, so as to turn the underground hidden pipeline into an internal video visible on the computer, which is convenient for the management department to make the most reasonable pipeline treatment plan according to the pipeline condition, and then evaluate it according to the inspection technical regulations and provide it with an important basis for formulating a repair plan.

The pipe CCTV inspection robot developed by Easy Sight is the most effective and accurate tool to access the pipeline, which is attached great importance to the sewer and drainage industry. It can use a pad, a laptop, or a special controller as its main control. During the inspection process, it can quickly grab the defect pictures. After the inspection is completed, the inspection report can be obtained immediately. In addition, the slope curve of the pipeline can be obtained in real-time during the detection process to determine the deposition inside the pipeline.  

Easy Sight owns five kinds of pipe CCTV inspection robots, that is, X5-HMA CCTV inspection crawler, X5-HT pipeline CCTV inspection robot, X5-HS CCTV inspection crawler, X5-HW pipeline CCTV inspection robot, and X5-HR screw-type crawler. Those robots are all lightweight, convenient to detect, and quick and stable with high definition.

Easy Sight's CCTV inspection robots have a digital high definition, with≥2 mega-pixel high-definition picture quality, and long-distance detection, like in the DN300mm pipeline, a single 300m long-distance detection can be realized. In addition, they have many extending functions. For instance, it can be equipped with professional photogrammetry software to perform 3D reconstruction and quantitative analysis of pipeline real scene through CCTV inspection video; It can be equipped with a laser projector to extract the internal contour of the pipeline synchronously during the inspection, and create a three-dimensional pipeline model for measurement and analysis; It can be equipped with a panoramic camera system to generate a panoramic expansion view of the pipe wall in real-time, and generate a three-dimensional imaging analysis report on the spot.

(2) Periscope detection (QV detection)

Pipeline periscope inspection (Pipe Quick View Inspection) is a method that uses pipe periscope to inspect the pipeline in the inspection shaft. As a kind of pipeline inspection technology, QV detection can not only solve the problem that the camera distance cannot meet the pipeline length and the upload rate is too slow to be synchronized but also can accurately determine the pipeline material defect, corrosion degree and its specific location. Its inspection result can be viewed as a basis for the assessment of pipeline conditions.

Many people would ask how does QV detection work? The staff can record and save the internal images of the inspected objects in real-time through the main controller on the ground. The defect images can be quickly captured and saved. The inspection information can be entered through the keyboard and displayed and stored in the video, which is highly integrated, compact and lightweight. They use video to monitor and photograph the state of deposits inside the pipeline, pipeline damage, foreign body penetration, leakage, and hidden connections of branch pipes. It can clearly see and record all the conditions inside the pipeline at a long distance, and then the video is transmitted to the ground master computer and stored. Professionals analyze all the video data one by one to fully and systematically understand the basic situation of the pipeline, and its drainage quality and operation, as well as the location of the outlet and the degree of damage to the pipeline, then write the pipeline inspection report to provide economical and efficient detection methods for pipeline maintenance and repair.

The advantages of QV detection are convenient design, simple operation, but its disadvantages are that it cannot detect the structure under the water surface, cannot perform continuous detection, and the detection distance is short at one time.

Easy Sight's X1-H series pipeline periscope, adopting QV detection, is mainly used for the rapid detection of the internal conditions of pipelines. It can clearly display the internal structural defects and functional defects of the pipeline and save it with video, fill in the inspection information on the spot and take screenshots. The main control is wirelessly connected and controlled, and data collection within 50 meters of the wellhead is smooth. The patented "wireless deep well transmission" technology can detect pipelines with a buried depth of 25 meters. Combined with the PIPEMONITOR drainage pipeline live supervision platform, it can realize equipment management, remote viewing of live video, trajectory playback of operation point, workload statistics and other functions.

This kind of pipe periscope is used for presurvey of pipe situation. It is equipped with laser measurement and a high definition camera, thus it can display the structural defects and the functionality of the pipe, and those defects will be recorded and saved. It is suitable for pipe DN1000-2000, under the working temperature of 20℃~50℃, and its distance-measuring range is 0.2m-80m.

(3) Sonar detection

Sonar detection uses sound wave reflection technology to perform sonar scanning for pipeline internal testing to detect and locate objects in the water, provide accurate quantitative data, and detect and identify pipeline damage. Sonar has the advantages of higher sensitivity, strong penetrating power, flexible flaw detection, high efficiency and low cost. It is suitable for full water or high water level in the pipeline without precipitation conditions. Its disadvantage that it can only detect the condition of the pipeline below the liquid level, but cannot detect the general structural problems of the pipeline. Sonar detection can be combined with closed-circuit television detection systems and various environmental sensors to conduct a comprehensive inspection of the pipeline structure. As the sonar travels in the pipeline, the software will automatically integrate the data and calculate a three-dimensional model of the pipeline to show to the customer.

X4 pipe sonar system of Easy Sight is designed to inspect conditions underwater mainly for the deposit and sediment. It can analyze and extract the inner wall contour automatically, which is mainly designed for the detection of pipes with water (full water or above 2/3 of the water level). It can detect wells or underground voids, automatically analyze and extract the inner wall contour, establish a three-dimensional model, and perform quantitative analysis. When applied to pipeline inspection, it can accurately determine a large number of structural defects (rupture, deformation, the concealed connection of branch pipes, disconnection, etc.) and functional defects (deposition, obstacles, residual walls, dam roots, etc.), and automatically calculate the amount of siltation and generate a longitudinal section view of the deposition state at the bottom of the pipe, through the combination of expansion components, the combination of CCTV and sonar can be realized for comprehensive detection (over and underwater).

4.Pipe inspection equipment for sewer system maintenance

With the development of pipe detection technology, the pipe tracing equipment is also updated at the same time. Easy Sight, as a famous pipe detection system supplier, has researched and developed a series of inspection products, including HD CCTV inspection robots, HD pipe periscope, sonar inspection system, CCTV & Sonar inspection system, 3D manhole scanner and so on. For example, the series of pipeline CCTV inspection robot products is the new generation of digital high-definition pipeline CCTV inspection robots. The pipeline robots can replace people to enter the urban drainage pipes to perform fine inspections through TV imaging and generate inspection and evaluation reports that meet industry standards and provide important analysis basis and guidance suggestions for maintenance and repair plans.   

Easy Sight not only uses the above methods alone but also combines the above methods to optimize the machine. For example, X7 CCTV&Sonar pipe inspection adopts both CCTV video detection technology and sonar imaging technology, therefore, it is also the best pipe locator as the best solution for conditions where you cannot drain the water. X7 CCTV&Sonar pipe inspection is composed of a sonar probe, HD P&T camera, cable reel, main controller, and floating boat. It uses a crawler or manual drag way to drive (glide, float) to move in the pipe. Taking a personal laptop or special controller as its main control.
