What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.
Water swelling seal, rubber sealing strip, sealing plate, the three theory can effectively prevent outside moisture through concrete construction joints with, from the analysis of the sealing principle, construction technology, the three is a big difference, the effect is different. Taking an underground three story structure in an engineering project as an example, the advantages and disadvantages of using the three structures in different parts are analyzed.
Water swelling, water stop, rubber water stop and water stop steel plate are compared between the three:After using the water stopping strip (water stopping steel plate and water stop bar), the water can be prevented from soaking through the concrete, and the double protection function of water proofing and water stopping can be realized.
