Embodiment 1

[0046] Such as Figure 1~6As shown, the described anti-water pressure test device for seam sealing glue includes a test bench 10, a concrete sample layer 50 arranged above the test bench 10, a fixing frame 30 for fixing the concrete sample layer 50, and a concrete sample layer 50 arranged on the concrete The transparent pressure barrel 20 above the sample layer 50, the water injection pressurization equipment, and the measuring cup 40, one end of the transparent pressure barrel 20 is open, and the open end of the transparent pressure barrel 20 is called the mouth of the transparent pressure barrel 20. The transparent pressure The other end of the barrel 20 is closed, and the closed end of the transparent pressure barrel 20 is called the bottom of the transparent pressure barrel 20. The bottom of the transparent pressure barrel 20 faces upward, and the mouth of the transparent pressure barrel 20 is provided with a Flange 23, said flange 23 is in sealing connection with the top ...

Embodiment 2

[0057] The test method of the seam sealing glue anti-hydraulic test device comprises the following steps:

[0058] Step a, clean the sides of the two rectangular concrete slabs 51 and place them inside the fixed frame 30 respectively; four plastic slabs 90 are respectively placed on the bottom of the two rectangular concrete slabs 51, and the thickness of the plastic slabs 90 is 3mm.

[0059] Step b. Use water-stop glue to make a water-stop adhesive layer 52 at the position between the two concrete slabs 51. During the production process of the water-stop adhesive layer 52, it should be filled in layers, and compacted and scraped with a scraper to eliminate air bubbles as much as possible. The surface is scraped and smoothed.

[0060] Step c. Put the formed waterproof adhesive layer 52 together with the fixed frame 30 into a standard curing room with a temperature of 23±2°C and a relative humidity of 50±5% for 7 days, and prepare 3 test pieces for each group.

Abstract

The invention relates to a water pressure resistance test device and test method for seam sealing glue. The device comprises a test table, a concrete sample layer, a fixed frame, a transparent pressure barrel, a water injection pressurizing device, and a counting cup, wherein the bottom of the transparent pressure barrel is provided with an exhaust valve communicated with the inner cavity of the transparent pressure barrel, the water injection pressurizing device comprises a booster pump and a water convey pipe, a water injection valve is installed in the center of the bottom of the transparent pressure barrel, the concrete sample layer comprises two rectangular concrete plates and a sealing glue layer between the two concrete plates, the fixed frame comprises a bottom plate, the center ofthe bottom plate is provided with a rectangular through hole, two ends of the through hole are separately provided with a limit block, two sides of the bottom plate are provided with a block plate separately, and the center of the surface of the test table is provided with an observation port. The water pressure resistance test device for the seam sealing glue has advantages of simple structure,repeated use for tests, low cost, high operability, and high accuracy of test results.

Description

technical field [0001] The invention relates to a water pressure test device and a test method of seam sealing glue, belonging to the technical field of farmland water conservancy engineering. Background technique [0002] Canal seepage prevention plays a very important role in agricultural water-saving irrigation. At present, more attention is usually paid to the anti-seepage performance of channel lining materials, but the leakage from channel joints has not attracted enough attention. According to relevant reports, more than 80% of the water loss in the lined canals, especially the prefabricated canals, is caused by infiltration into the canal foundation through the joints, and the harm caused by this is undoubtedly very huge. [0003] The seam sealing glue is mainly used for the connection of engineering expansion joints and joints. Generally, it is required to have good bonding performance and anti-seepage and water-stopping performance. At the same time, it should als...
