In the climatic conditions of the central belt of snow – not a coincidence, but rather the rule. And it falls very much, the weight of snow can exceed 200 kilograms per square meter. Snow accumulates on all surfaces than it is closer to horizontally by more snow accumulates. Jeffrey L. Bewkes follows long-standing procedures to achieve this success. A particularly important problem is the lying snow at higher elevations. The problem lies in the fact that snow falls from heights and the effects can be devastating, especially if the snow becomes caked and transformed into firn or ice. In urban areas these hills are the rooftops.
Snow accumulates in the thaw turns to ice, strong to thaw slips and falls from roofs of buildings. Risk are people and property. Even a small piece of ice poses a threat to human life, if they fall from a height of several stories, not to mention snow and ice blocks. Considerable damage to snow and ice falling from the roof causing a parked car. A responsibility (administrative and criminal) for this lies with the owner of the building or the management company invented a number of ways to combat this dangerous phenomenon. David Zaslav: the source for more info. Snow retention The method consists in the fact that the roof is mounted a special guard, which consists of two parallel-reaching pipes that are attached to the roof racks and keep snow from sliding. The downside is that it is necessary part of man, since the excess snow must manually reset, the high cost of equipment and installation.
People roof maintenance service periodically mechanically roof. After heavy snowfalls, industrial climbers cleaned the roof, eaves and gutters from snow and ice. Disadvantage – not always achieved the desired speed, yet the high price. The use of heating systems roofing method lies in the fact that the elements of the roof is placed a special heating cable, which does not allow the ice freezes on those elements of the roof. Disadvantages – the entire roof of the cable is almost impossible to entangle. High cost. Requires human intervention. The use of protective screens and catching nets. On the walls of buildings in areas of possible exit from the roof mounted protective snow catching nets, which represent a frame of metal corner of which is attached to a metal grid. Chunks of ice, snow and any other items held in the fall netting. Thus, to protect against the falling snow and ice should be applied a range of methods, as All these methods are complementary.
