Water-filled dams

In the territory of Russia NPF “Politekhnika” LLC is a pioneer in the production of flexible water-filled hose dams (WFD). This is a soft tank made of flexible elastomer that allows you to literally organize quite reliable protection against flooding or flooding in just a few tens of minutes. In the event of a natural disaster caused by water, the practice of using sand-filled sacks from which protective dams are laid is widespread. This is a fairly effective precautionary measure, but this practice is very resource-intensive and implies serious material costs. At the same time, one 25-meter WFD is able to replace the protective structure, consisting of thousands of bags filled with sand. WFD elastic dam: device As noted above, the water-filled dam is a soft and elastic tank in the form of a closed sleeve, the outer shell of which is made of synthetic fabric. Under the shell there are two internal hermetic chambers made of multiple layers of polymer film. The sleeves are equipped with coupling sleeves, as well as drainage systems for draining the water, and special plugs allow, if necessary, to connect a pump or a motorized pump to the dam for pumping water. The sleeve shell is equipped with special lines, which allows you to securely fix the dam with a cable, in case it is used on inclined surfaces. A characteristic feature is the convenience of transportation, as in the folded state of the WFD, is a compact roll, placed in a special case or an ordinary box made of wood. One set consists of four sleeves. The length of each individual sleeve is twenty-five meters. Moreover, it will take only 15-20 minutes to complete the installation and commissioning of such a kit. Application area: Elastic water-filled dams are used to protect various objects from natural disasters of a water nature, as well as during any repair and construction of water mains, canals and other water supply networks. The composite materials from which the hoses' reservoirs are made allow for the use of elastic dams in a variety of situations, which is a huge advantage over other types of similar products. The advantages of the WFD are difficult to overestimate, since other types of protection are noticeably inferior to them in the effectiveness of their application in many ways. On the example of bags filled with sand, it can be noted that even compactness and speed of application are already an excellent indicator in favor of the WFD, while the traditional method significantly loses in delivery time, installation speed and price. After all, it is not for nothing that practical Europeans have been using this technology for a long time in case of an emergency need to combat water and protect their homes, educational and medical institutions, and other important facilities. The advantage of soft WFD Standard requirements for equipment used to deal with and deal with the effects of natural disasters are: * structural reliability; * maximum installation speed; * high performance; * acceptable price; * minimal transportation problems. All products of NPF Politechnika LLC fully comply with these requirements. And although many industrial buildings, as usual, use traditional “bag-sand” barriers, made of composite elastomer dams are simply indispensable in their field of application. It should be noted that the installation and filling of the structure, having a length of 1000 m, takes no more than half an hour with a sufficient number of people. Flexible WFMs manufactured by NPF Polytekhnika LLC have been approved and widely used in the units of the Emergencies Ministry of Russia and other rescue services.
