Precautions for the construction of fully automatic concrete impermeability tester

The fully automatic concrete impermeability tester is a testing instrument used to determine the passive permeability of concrete. It generally consists of a control system, sampling station, detection head, signal transmitter, power supply, etc. It is a device designed to determine whether concrete has sufficient impermeability. The principle is to place concrete on the specimen plate and then implant the pipe collection end into the concrete; Connect both sides of the detection head to a determined liquid medium; Apply the storage pressure of the detection head to the concrete specimen to generate stress; Transfer the data collected from the detection head to the control system for processing; Determine the permeability of concrete through specific calculation algorithms and comprehensive analysis

Fully automated testing, no need for manual interference, accurate and fast, can conduct continuous testing for a long time, with accurate and excellent measurement results and strong repeatability. It can test large areas of concrete specimens and obtain accurate measurement resultsIn concrete construction, it can effectively improve the passive permeability of concrete, thus the actual effect is mainly based on the performance of concrete materials, further improving the service life and quality of concrete in buildings

1、 Before construction, it is necessary to familiarize oneself with the instruments, fully understand the various functions and parameter settings, and then carry out construction according to the prescribed operating procedures

2、 Confirm the use of correct equipment and materials during construction to ensure good performance and operation

3、 Choosing a good installation environment on the construction site should avoid adverse factors such as water stains, flames, and direct sunlight as much as possible to protect normal use

4、 Check the switch power supply, which should have grounding protection and ensure that the grounding does not exceed 30 ohms

5、 The concrete testing fluid should be used strictly in accordance with the provisions of GB50797 "Testing Method for Concrete Fracture and Impermeability Time in Building Engineering" to confirm the accuracy of the test

6、 When using, attention should be paid to safety, no illegal driving is allowed, and the switches on the control panel should be operated and adjusted correctly

7、 After the construction is completed, a thorough inspection should be carried out to confirm the integrity of the cement slurry, the anti-seepage performance meets the requirements, and to protect the construction quality
