Data processing method and device for external wall water spraying

Abstract

The invention discloses a data processing method and device for water spraying on an external wall, which is characterized in that it comprises the following operation steps: step S1, image acquisition; S2, image generation; S3, image display; S4, status assessment; the beneficial effects of the present invention are , the water spray device can be accurately positioned to the water spraying test section through the stabilizing device and the transmission device, which saves the complicated process of manually arranging the water spray device, making it safer and more efficient to work at heights; through the water pressure sensor, water pressure sensor The setting of the module and the numerically controlled pressure regulator makes the spraying water pressure control within the specification requirements during the test, and the spraying test effect is more ideal; the three-dimensional image collection can be realized through the monitor, which can not only automatically identify the leakage situation, but also Leakage warning information can be issued, thereby improving the accuracy of technicians in judging the leakage status of the external wall; there is video monitoring throughout the test process, and the test video is saved in real time, providing a decision-making basis for the leakage rectification plan.

Description

technical field [0001] The invention relates to the technical field of prefabricated exterior wall detection, in particular to a data processing method and device for exterior wall water spraying. Background technique [0002] The joint waterproof construction of prefabricated concrete structures is a very critical quality inspection content, and it is the key to ensure the waterproof performance of prefabricated exterior walls. The prefabricated concrete building construction quality acceptance specification DBJ / T15-171-2019 clearly stipulates that after the prefabricated exterior wall is installed, the exterior wall water spray test should be carried out, and the waterproof performance of the exterior wall can only be accepted if the water spray test is passed. [0003] The traditional water spray test detection method is that after the water pipe is connected to the tap water, the personnel go to the high-altitude outer wall or balcony through the high-altitude hanging ro...

AI Technical Summary

Problems solved by technology

[0007] 1. Most of the test plans do not provide water pressure control means. Even if it is mentioned, it is impossible to ensure that the pressure stabilization control will be carried out throughout the test process, and the test results are still not ideal;

[0008] 2. In the current popular water spray test and detection method, the layout of the water spray device is basically manual operation, and the current popular water spray equipment in the industry is relatively simple. Even if the improved version of the above patent design is used, there are still devices The problem of large volume and difficult operation, and high-altitude operation is dangerous;

[0009] 3. In terms of alignment between the water spraying device and the water spraying test section, the installation position of the water spraying device is determined by personnel's visual inspection. This method is difficult to operate and there will be large errors in positioning;

[0010] 4. At present, there is basically no mention of how to record the test video of the whole process of the test. Although it is possible to take pictures of the water-sprayed part within a specified time period and use it as a basis for judging whether the part leaks, but when When a leakage occurs, it is impossible to accurately judge the location of the leakage through photos, and it is difficult to provide a decision-making basis for the leakage rectification plan;

[0011] 5. During the entire water spraying test process, whether the water pressure of the spraying water is achieved in the whole process, and whether the spraying position deviates, these aspects need to be confirmed by personnel at all times, which consumes a lot of labor costs

[0012] Not only that, because the water spray test takes a long time, some project sites do not completely follow the specification requirements when conducting the water spray test, and do not fully control the test conditions. They only take pictures at the time node and use it as a test to determine whether the test is qualified According to the basis, the effect of the test in such a state is far from meeting the requirements of the specification for waterproof performance, which may eventually lead to complaints from the owner due to water seepage on the outer wall after the project is delivered, causing adverse social impacts. In view of this, the above-mentioned After in-depth research on the problem, this case came into being
