This standard is based on (1.3-1997 standardization work number 1: drafting and expression rules of standardization part 3: product standard compilation regulations" formulated. The product of Yingrungongji rubber water-swelling waterstop is a new type of water-sealing village material. It has been used in the water-stopping of injection and structure constructions for many years, and it is also used in the water conservancy engineering of underground super construction projects. The actual combat of water stop and waterproof net has achieved good results, but the laser products can not only adopt international standards, but also other foreign standards, and domestic has not yet formulated relevant national scientific and industrial standards. In order to better regulate the market, many enterprises producing such products in China rely on this standard. The Standardization Institute of the People's Republic of China and the Ministry of Construction of the People's Republic of China proposed this standard and the Ministry of Forestry and Forestry Products Standardization Technical Practice Committee 1. The originating units of this standard are: Sichuan Provincial Forestry Science Research Institute, Sichuan Provincial People's Government School: Chengdu Qunte Waterproof Material Co., Ltd.
The main drafters of this standard: Jin Canliang, Chen Xian, Yun, Li Wanli: 274
This standard specifies the product classification and model, requirements, test methods, inspection rules, marking, packaging, transportation and storage of water-swelling rubber water-stop strips. This standard is suitable for water-swelling rubber water-stop strips made of three materials, such as rubber and other materials. 1. The standard is used for the whole water-stopping of departments, tunnels, and waterways. 2 Cited standards

5.3.2.2 Test steps
Start the water resistance test, check the left flow, shut down: replace the test sample and cover the water, and then install the test sample to eliminate the test fence; the real piece used half a piece: install the seat piece, tighten the end plate and the test building main body to connect the call: start the water policy, feed tap water into the test model, record! Starting time, pressurization is required every 5m, and the station is always fully connected. When the water pressure method is U.Ma, it can be pressed every 10min. When the gauge reaches .51MT or more, pressurization is required every 2 hours until the specified pressure is reached. The whole test rod shall not be left in place for 24 hours, and the time shall not exceed 240h. 5.3.2.3 Pay attention to the main items: a) The test rod must be filled before it can be tested: and ensure the density and surface half of the sample. No defects. ) Test process: When the pressure is cut off, the water is stable before the ground is grounded. Do not suddenly apply the designed water pressure. 5.3.2.4 Test results: Each group of three units can maintain the water connection for 30m under the specified force. 5.3.3 Water expansion rate: 5.3.3.1 Test standard: Use 3 small load samples of about 0m, each about 4 meters high: on a flat railing of a bridge type support frame, use ten tests. 5, 3.3.2 or test steps: According to CB/TI, measure the mass M of the test sample in the air, and the weight of the sample in water. After combustion, the sample will be passed through the specification. The mass M of the test sample in the air and the mass of the sample in water are determined every 2 years. , the sample is recorded in water until the water absorption rate no longer increases as positive, (type product to be calculated 24, S type product 45.3.3.3 test frosting
