In Chernihiv, Prospekt Mira set new hatches
In Chernihiv on April 19 Mira Avenue, the street Kotlyarevskogo street Flight, units of KP "chernigovvodokanal" we have already begun the overhaul manholes water supply system. Yesterday installed a new well and replaced two manhole covers. This year all work performed on new technologies using hatches class D400, manufactured by the Czech concern KASI from high-strength cast iron with spherical graphite. These hatches are protected against ejection of the cover from the housing under the wheels of cars and withstand the extreme load from 52 to 55 tons. On the main streets of Chernigov (Mira and Ivan Mazepa street), where for the second consecutive year of road works on repair of asphalt pavement, executed repairing of wells, the construction of the chambers and replace the hatches. After inspection of the site of Mira Avenue (from the street. To Kotlyarevskogo str. Flight) it was found that under the replacement fall 38 manhole covers water directly on the roadway and the highway 4 sewer manholes adjacent to Avenue road. In addition, it is necessary to perform capital repair of wells, is made of red bricks and make them concrete. Because the brick – the material is not reliable after a year or two under the influence of moisture and loads turns back into clay. Basically, that's what happens subsidence or failure of wells on city roads. Also closer to the street Flying under the road will be constructed water chamber – a room 3,5x3,5 meters to accommodate valves of a water main. New technology of installing sunroofs is that instead of bricks for the manufacture of the neck of manhole began to use concrete ring and the rather expensive Assembly mixture IZOLSAN HF. The use of fast zastiglo mixture allows the use of a concrete support ring for the rehabilitation and construction of wells penetrating into the smallest cracks mixture turns ring and the hatch continuous design, which was essentially impossible with conventional cement. The fact that IZOLSAN acquires its characteristics already 30 minutes after use, allows you to open the traffic on the spot repairs is actually using the same 30 minutes after the pavement manhole covers with asphalt. It is also important that the new technology allows to install the manhole covers level with the road surface with millimeter precision. So, according to the technical specifications from the road, after the installation on Mira Avenue, the manhole covers will be raised above the level of asphalt is 4.7 cm Is the excess done to further the laying of asphalt pavement on the roadway, the manhole cover was flush with the road. After completion of the work on prospect Mira, the repair work will be started on the street. Ivan Mazepa, as well as on other streets, where the planned overhaul of the coating. KP "chernigovvodokanal" draws drivers ' attention to the fact that the area of prospect Mira, Kotlyarevskogo str to str. Flight covers manhole covers are set at 4.7 cm above the existing level of asphalt pavement. So one must be careful to avoid assaults on installed cover. Exceeding the height of the manhole covers above the road level will be eliminated after the laying of the asphalt layer during the renovation of the specified area of prospect Mira.*/blockquote */blockquote According to press service of the KP "chernigovvodokanal"Ïåðåâåäåíî ñåðâèñîì "ßíäåêñ.Ïåðåâîä÷èê": translate.yandex.ru.
