Problems solved by technology

However, the cost of this impermeability testing machine is high, and the detection area of ​​the sensor is limited, and the leakage point cannot be found in time. It must be judged after the water seeps into the detection range, and there is a certain delay in the judgment time.

Embodiment 1

[0028] The present embodiment describes in detail the automatic monitoring concrete impermeability test system of the present invention, as figure 1 As shown, it includes an impermeability tester 1, a test piece 2, a monitoring device 3 and a monitoring terminal 4. The monitoring device 3 includes a camera 31 and a hard disk video recorder 32 connected to each other. The hard disk video recorder 32 is connected to the monitoring terminal through a wired signal or a wireless signal. ; wherein: every six test pieces 2 are installed on an impermeability tester 1, the monitoring equipment is installed on the upper end of the test piece 2 through the support 4, and the video camera 31 is relatively set with the test piece 2, and is used for regularly taking photos of the test piece 2 End face picture, and it is regularly saved in the hard disk video recorder 32, and the hard disk video recorder 32 uploads the picture in the monitoring terminal 4, and the staff can check the picture ...

Embodiment 2

[0031] This embodiment is on the basis of embodiment 1, has increased alarm device 6, and it is connected with monitoring terminal 5, as figure 2 shown.

[0032] In this embodiment, the end surface area of ​​the test piece 2 is divided into a peripheral area 21 and a middle area 22, such as image 3 As shown, the peripheral area 21 is an annular area between the ring 30mm from the edge of the test piece 2 and the edge of the test piece 2. If water seepage occurs in this area, it means that the periphery of the test piece 2 is not sealed well, and it needs to be re-sealed. Sealing; the middle area 22 is a circular area within a circle 30mm away from the edge of the test piece 2. If water seepage occurs in this area, it means that water seepage occurs in the concrete. Record the time and water pressure at this time, and the water pressure is is the water pressure that the specimen can withstand.

[0033] In this embodiment, the grayscale image recognition system 51 is also lo...

Embodiment 3

[0036] This embodiment is based on the embodiment 2, and the surface of the test piece 2 is coated with the water-changing ink after 0.5 mm. When there is no water seepage, the surface of specimen 2 is white; after water seepage occurs, the water-changing ink becomes transparent, exposing the color of concrete. Apply the water-changing ink or the surface color of the test piece 2 before and after water seepage changes obviously, which is easy to distinguish.

[0037] When the water-changing ink is not applied, the difference in gray value must exceed 30 to determine that water seepage has occurred. At this time, it has been a period of time since water seepage occurs; after applying water-changing ink, the difference in gray value is as long as If it exceeds 20, or even exceeds 15, it can be accurately judged that water seepage has occurred, and the time is closer to the real time of water seepage, and the result is more accurate.

Abstract

The invention discloses an automatic monitoring concrete impermeability test system. The automatic monitoring concrete impermeability test system comprises an impermeability tester, test piece and a monitoring device, wherein the test piece is mounted on the impermeability tester; the monitoring device is mounted over the impermeability tester through a support in a manner of being opposite to the test piece, and is used for periodically taking photos of the end face of the test piece and storing the photos. With the automatic monitoring concrete impermeability test system provided by the invention, workers can check and record test conditions of all the test pieces in an office through a monitor at any time without observing in site.

Description

technical field [0001] The invention relates to the field of concrete anti-seepage test, in particular to an automatic monitoring concrete anti-seepage test system. Background technique [0002] The national standard concrete impermeability test method T0528-94 stipulates that there are six concrete specimens in each group. During the test, the water pressure starts from 0.2MPa, and the water pressure is increased by 0.1MPa every 8h, and the end surface of the specimens should be observed at any time. When water seeps out, record the location number of the sample and the indication of the pressure gauge at this time, add until water seepage is found on the surface of three of the six test pieces, record the water pressure at this time, and then Stop experimenting. When the pressure is increased to the design impermeability mark (specified pressure), after 8 hours, it is found that there are still less than three test pieces with water seepage, indicating that the concrete h...
