Using modern technology there is in all human activity. They can significantly reduce labor costs and speed up any virtually any workflow. When working with pipes used technique teleinspection. Next, consider what it is, which species is and how spent.
What is teleinspection sewer pipes
To begin with we shall understand that represents teleinspection for sewer pipes. It consists of a set of equipment, the main of which is the DVR. With it passes teleinspection pipelines without opening them. The device is lowered into the inner cavity of the sewer pipe.
What is performed and when required
Conducting Video diagnostics of pipes for sewerage aimed at rapid identification of gaps in pipes. Study of condition of the internal cavities of pipes, without parsing, via DVR allows to reveal defects formed. Subsequently their removal takes place from the outside techniques, either using the device to work inside.
CCTV inspection of sewer pipes may be required in the following cases:
- In the event you need to be connected to the existing sewerage system. In this case, the use of tele-diagnosis system will be needed to assess the status of the place of planned connection of a new drain.
- To localize the site of injury and repair in its further particular node. This reduces the cost of full excavation or recess of the common riser. Such work can be performed for the early detection of wear of the walls, which is shown with the scheduled aging equipment or in emergency operation. In the formation of large breakdown in sewer pipes, may have problems with flooding or subsidence of the walls of the riser, depending on the method of installation. These factors are significant damage to the ecological state of the environment. Therefore, the use of said apparatus is topical.
- Diagnosing the state of the sewer pipe. The procedure is required when working devices using telemetry system. It is aimed at identifying possible defects at an early stage of formation. This can significantly reduce the costs of scheduled work. You do not need to remove the worn areas of sanitation. To address the identified defects using robots that strengthen weakened areas.
- In the formation of congestion in the sewerage system of private and public buildings. With equipment, you can quickly determine the place of formation of congestion. This will allow to take appropriate measures to restore the normal passage inside sewer. C. Video inspection during scheduled inspections, it is possible to determine the likely locations of metal transfer which may lead to congestion.
- For the analysis of the newly installed pipes to be for commissioning. The procedure is mandatory for execution. In the process of acceptance of sewerage pipelines, CCTV inspection system is able to determine the carrying out of installation works. If necessary, repair any defects. As a general rule, all expenses borne by the contracting organization, conducted the installation work.
The technique aims to verify that none of these shortcomings:
- the availability of various types of debris;
- finding foreign objects in the pipeline;
- monitoring unreliable joints in places docking;
- presence in the inner cavity of sewer pipes mechanical damage.
used equipment
Video diagnostics of sewer systems can be carried out, which differ in the modification and execution of mind. The base part thereof has identical elements. It consists of the equipment:
- surveillance camera, which is placed in the sewer;
- unwinding place the camera cable and the monitor for visual inspection;
- Hard cord to push the chamber;
- LEDs, intended to improve the illumination during video shooting;
- sensors for determining the distance;
- monitor to display an image from a surveillance camera.
Surveillance camera configured so as to focus the shooting in the middle. This allows the operator to view the sewer pipe wall in full screen. Also, the camera is performed with increased protection against moisture and dirt particles.
With tough cord, you can change the shooting direction of the camera. This allows you to examine in detail the required sewage station. A device with sensors which determine the distance traveled by the tool. This allows you to accurately determine the location of the blockage or damage. When using the device without connecting cable control via remote control.
Benefits teleinspection
Application of Video diagnostics sewerage system facilitates rapid assessment of and finding damaged places without disassembly of the pipeline. The system can significantly reduce labor costs in carrying out such works. It is distinguished by the following advantages:
- In carrying out periodic inspections of sewage can be avoided complex repairs, as well as prevent the development of an emergency.
- The video surveillance system allows otsmotret the smallest defects in the cavity.
- The operation will need to expend the minimum amount of time.
- You can control the state of considerable length, without violating their integrity.
- Works with CCTV inspection system is not required to carry out actions to dismantle the drain.
Order of works
Production work begins with the preparation equipment. First the monitor for receiving image before analyte conduit. Then comes the input of surveillance cameras in the studied sewage station.
When using push teleinspection system operator gradually unwinds the coil with a rigid cord, at the end of which a video camera is located. Promotion occurs on the inner cavity of the device.
The camera has a high resolution and is equipped with LED backlight, which allows a better view of all the flaws inside. The image is transferred to the operator's monitor. Camera with built-in sensors monitored distance. This makes it possible to accurately determine the location of the damage.
To change the viewing angle in the inner cavity, the operator must change the location of the cable, by twisting it. In the future, there is a study of findings, and outlines the required work plan, depending on the nature of the damage.
In the case of self-propelled devices teleinspection operator starts the internal cavity sewage automatic robot. Its movement will be using the remote control. So the option of changing the direction of video cameras shooting angle. The apparatus also completed with sensors for monitoring distance traveled. At the end of the work, you will need to study in detail the resulting video. Based on it to draw a conclusion about the need for repairs.
Types of CCTV inspection systems
There are various types of CCTV inspection. Their design concept and the characteristics may vary based on the problems to be solved. Important is the complexity of the execution of sewer pipes. By way of distinction floating action and pushes the device.
CCTV inspection systems for sewer divided into the following types:
- Kicking - at their base using rigid cable with a cable for transferring images on the video monitor. The cord is used to push the inner cavity of the DVR.
- Propelled - able to independently move through the channels of pipes, using a remote control.
- Satellites - these systems are equipped with two or more cameras. They are designed for the integrated analysis of sewer pipes with many branches.
The systems are designed to operate in pipes with a diameter from 25 to 2000 millimeters. The length of the action of the device depends on the particular modification. Most large instrument operation length is 250 meters. Currently, systems are being developed to work on the length of five hundred meters.
The simplest system for monitoring the state of pipes, allow only transmit the picture on the operator monitor. When using more advanced systems can use the video recording mode for further detailed analysis. Systems differ in the type of camera used. They have an extension, the higher it is, the better the image is transmitted to the operator monitor. Device modifications differ in functionality and price.
Using teleinspection sewerage system allows you to get information about their condition. The order of execution of works is simple and does not require much labor. With systems can quickly identify and correct defects without dismantling the existing sewer pipe. This reduces the risk of major accidental breakages, which are accompanied by large economic costs and the harmful effects on the environment.
