Big bridge preload bag manufacture

Big bridge preload bag manufacture Hengshui City Zhengda bladders factory is specialized in the production of bridge preload bladders manufacturer. Bridges preload bladders products have been widely used in the construction of railway bridges, highways in. In bridge construction phase, the bridge load testing is a key pre-press work of a project quality standards detection. I produced the preload is the use of rubber nylon bag (2 layers of nylon cloth rubber), high density polyethylene. And the two can overlap the pressure to meet the bridge preload tonnage, which is full of small water, the density of water, it has a high efficiency, low dynamic strength, space civilization, clean and so on. Because preload bag, preload bladders test is simple, accurate, low cost and reusable and other characteristics, it is the ideal choice for the future bridge preload. Preload bag, preload bladders Versatile: can meet the needs of different projects and preload preload area, conventional bag is 1.5 meters high, the highest combination can reach 4 meters high. Preload bag, preload bladders Specifications Model: 5t, 10t, 15t, 20t, 25t, 30t, 35t, 40t, 45t, 50t, 55t, 60t until the maximum 500t, 1000t bag has. Engineering test pressure bag to use: 1, the bladders needed to spread out onto the platform, be careful not to have sharp things on the platform, so as not to damage the rubber bladders. 2, such as the height of more than two meters of water bladders, they must press the rubber bladders around the size of the product with sandbags (or other methods such as scaffolding) reinforced rubber bladders to reduce the pressure on the pressure side to avoid bursting bladders and scrolling. 3, using pumps or water, the pipes connected to the inlet valve bladders, open the inlet valve and the exhaust valve switch, the internal air bladders excluded. Began to water, to be later filled bladders, and then close the inlet valves and exhaust valves. 4, to prevent nails or sharp hard object punctured rubber bladders, if cut, but with a wheel or rasps fight hair, brushing watering tape covering repair, it is best to use the manufacturer's recommended the use of glue repair water bladders bag, place the appropriate time to use.
