The invention relates to hydraulic construction and can be used for performance monitoring of the technical condition of the flume channel irrigation systems, detection of dangerous defects and damages, as well as assessment and forecasting of the technical condition of the concrete flume irrigation canals and further their suitability for use.

The closest in technical essence is the ultrasonic method of monitoring the strength of concrete in concrete and reinforced concrete structures during the operation (registration number 2262687).

The disadvantage of this ultrasonic method of monitoring the strength is that it includes the measurement of ultrasound in samples-cubes, not the facility itself, which is an expensive and long procedure. During the survey no complete picture about the technical condition of the entire structure.

The technical result achieved by the present method is the detection of defects and damage in the gutter channels of irrigation systems. This method also allows for each concrete tray irrigation canal to assess its stress-strain state and the prediction of remaining lifetime.

This technical result dost is presumed to those a method for carrying out operational monitoring of the technical condition of the flume irrigation canals make a survey of reinforced concrete flume channel devices of non-destructive testing for defects and damage, using two mutually controlling methods: ultrasonic method and the method of the shock pulse and determine the depth, width, length (geometry) and the actual strength of concrete at locations of defects and damage. In progress establish uniformity and strength of concrete of each tray, and the degree, type and depth of corrosion of concrete and reinforcement, the nature of the cracks and their width. When using this method, you receive the possibility of justification of parameters of defects and damage that cannot be set by visual inspection.

Figure 1 shows a concrete tray in axonometric projection, figure 2 - end view, figure 3 - side view.

To conduct operational monitoring of the technical condition of the flume channel irrigation systems using non-destructive testing devices (using the ultrasonic method and the method of the shock pulse) taken concrete tray, which is divided into three zones examination to detect typical defects and damage for each zone.

During the field surveys established characteristic hazardous defects and damage (leading to the destruction of structures) concrete trays, and place of their formation (oblique cracks are formed on the ends of the tray, longitudinal cracks are formed along the sides, the destruction of the concrete occurs at the bottom of the tray).

On this basis, designate three areas of study: zone 1 is examined to identify defects and damage of the destruction of the bottom part of the tray, her appoint the entire length of the concrete bin width equal to1/3from the perimeter of the tray; zone 2 - examined on the subject of education oblique cracks in the side of the tray, her appoint 1.2 m from the ends of the tray along the length of each side; zone 3 - on the subject of the education longitudinal cracks, which lead to the collapse of the bead tray, it is prescribed along the length of the side between zones 2.

The findings characterize the technical condition of the flume irrigation canals.

The advantage of the proposed method over the known is that the proposed method of carrying out operational monitoring of the technical condition of the flume channel irrigation systems is easier and more reliable compared with known as it applies two mutually controlling method is non-destructive and allows to identify the Def the points and damage of the flume channel, and also to make the assessment and prediction of their technical condition.

The method of carrying out operational monitoring of the technical condition of the flume channel irrigation systems using non-destructive testing devices using ultrasonic method and shock pulse method, characterized in that the concrete tray is divided into three zones examination to detect typical defects and damage for each zone: zone 1 is examined to identify defects and damages, leading to the destruction of the bottom tray, zone 2 is examined on the subject of education oblique cracks in the side of the tray, zone 3 - on the subject of the education longitudinal cracks, which lead to the collapse of the bead tray, on the basis of the received data predict the technical condition of the flume irrigation channels systems.

2. The method of carrying out operational monitoring of the technical condition of the flume irrigation canals according to claim 1, characterized in that zone 1 assign the entire length of the concrete tray and width equal to 1/3 of the perimeter of the tray, zone 2 assign equal to 1.2 m from the ends of the tray along the length of each side, the zone 3 to designate the length of the side between zones 2.
