From rain and frost

Mikhail Skvortsov Protection exterior communication network remains relevant as far as actual bad weather in our region and filled with soil moisture. And if you've paved the pipe or cable outside the house, then try to neutralize or at least minimize the impact on them of negative external factors. Such factors have, frankly, in excess. First, always pour from the top, but the fact that the top, is inevitably in the soil. Secondly, the bottom is also constantly threatened by "flood" ground water, which, combined with atmospheric moisture present answered by a serious danger to networks installed in the ground. But moisture is not all there is such a thing as frost heaving of the soil. Soil due to this shift, and with such force that squeezes out of the ground even for houses. What to say about some unfortunate pipe? Different parts of the soil may then shift to a different intensity, a result of which the pipe or electric cable elementary bursts. Of course, the best option - where all communications are concentrated within a well-heated homes. However, alongside modern cottage, as a rule, is Bath. Need a guest house, perhaps, the garage will be separated, and the boiler in our time are often put to one side of the house, which increases the security of living and reduce environmental harm. This means that the inevitable strip of sections of pipelines and power grids. We list to start outside engineering services of a modern country home. Let's start with the fact that any home need water for drinking and household needs. In certain exceptional cases, the well can be located directly under the house, going out into the warm basement, and if any problems with the supply of water there. However, in most cases, well, well or pipe water mains are located in the side, and you have to lay a water pipe on the site. But you need not only to bring water to more and somehow get rid of sewage. And because the septic tank, certainly not put under the house, it becomes necessary to withdraw beyond the building sewer pipe and lead it to the local sewage system. Another version of the external networks to suburban areas - is the outer pipe heating systems. We have already mentioned that in some cases required to heat the building, facing away from the house and, therefore, need to lay another pipe under the ground. Finally, no country home is not without electricity. Sometimes the electricity enters the house through air networks, sometimes through the cables laid in the ground. It is also possible independent cabling on site - in the same bath or lodge for guests. All of these utilities themselves have some degree of protection from the environment, but this usually is not enough, and requires special measures. Ways to protect in the first place to protect against external influences should be water pipes. Least because the water in them - cold, and at any temperature drops below zero there is a danger of water freezing in the pipeline, which consequently will simply break. Therefore require specific activities of the thermal insulation of pipes. First of all, we say that such a pipeline should not pass over the land in any case (or it should be operated only in warm seasons, and the rest of the stand without water). It is necessary to bury the pipe cold water into the ground, not on two feet and not even a meter. The average depth of soil freezing in our region is 1,2-1,5 meters, therefore, to lay pipes preferably deeper. This will be the main event of the thermal insulation of water pipes, as the depth below the freezing temperature is always plus. In this case, can be used with insulated pipes, but this is not a fundamental requirement because there is no need to keep a portable heat (as in the case of heating pipes). Much more serious demands on the seal and, in particular if the pipelines of steel. Everyone knows that the steel structure on contact with water are subject to corrosion and deteriorating rapidly. Therefore it is necessary to use pipes with external insulation, reliably protecting the pipe from contact with soil moisture. Particular attention should be paid to waterproofing pipe joints subjected to abrasion of small particles carried by groundwater. It also helps to reduce the service life of pipelines. It is also important and the quality of protection outlet drain. Sewer pipe connecting the house and septic tank should be located in the zone of zero temperature. Otherwise, run-off, too, will freeze the pipe burst and in the spring, when everything thawed, the site will be spread foul smell. The safest and most radical way out - again, laying the pipe below the freezing ground. Seriously need to approach such problems as the protection of the local sewage from groundwater. First, the outlet pipe should be one way or another seal the - this will allow for a long time to avoid their destruction (the destruction of such fraught - it is already clear). Secondly, if the ground water come close to the surface, drainage should settle in a certain way. This is not to equip the system with soil filtration, because the waste will be spread across a water horizon. You can only use septic tanks, preferably with plastic housing (concrete and metal is not as tight and may be filled with groundwater). Plastic septic tanks are easy to install and operate up to 50 years. Septic tank it is necessary to strengthen the good around him should be placed drainage tube to drain excess water. Heating at any given area - is now not uncommon, as many homeowners are reasonably decide to carry home a source of noise and pollution - the boiler room. This option is more expensive, and necessarily entails the laying of pipeline from the boiler room in the house. Carry such pipes and guest houses, and hozbloki, and here the most important thing - do not lose precious heat on the road. Pipe heating system, too, are laid below the level of soil freezing. But they must be insulated, because the temperature of soil at depth - slightly above zero, and the open pipe will rapidly lose heat. As a result, heating is formed along the Thaw, and the house radiators are barely warm. Heating pipes can be insulated, both during installation and purchase of ready-made insulation. Particular attention should be paid at the same time on the insulation of joints, where the risk of heat loss increases. Protection of heat from the ground water is also necessary for reasons already stated. Although these activities to increase the reliability and longevity of such features in the pipeline is still not obtained. The problem here is the very material from which pipes are made. Typically, metal pipes have a lot of welds, which increases the likelihood of an emergency at the site. Thermal insulation is also often not the best quality, in addition, the metal susceptible to corrosion, and buried her risk increases significantly. Address these shortcomings can be, if instead of steel used plastic piping. They are also suitable for heating a country house, and for hot water and cold water. These pipes are made of crosslinked polyethylene. And because PE is chemically neutral, corrosion is excluded. And if the pipe does not rust, it is not destroyed and is much longer. Lifetime of polyethylene pipes is 50 years old, which is quite comparable with a lifetime building. Another plus polyethylene pipe - the possibility of laying above the freezing ground, which reduces the amount of earthworks and accelerates the installation of the pipeline. This requires a very high quality thermal insulation. Polyethylene foam with closed pores absolutely perfectly retains heat. Elasticity of heat-insulating layer promotes the flexibility of pipeline systems, and protective corrugated casing causes the lining of the soil with a high level of ground water and even in hostile environments. The use of plastic pipe solves the problem of multiple welds, which are inevitable in any steel piping. Plastic pipes are supplied in coils, up to two hundred meters, they can be easily bent, and sometimes are placed in the ground directly from the coil. Compounds in this case is much smaller than that of steel pipelines, and the reliability of plastic - much higher. Finally, new heating pipeline deprived of a fundamental lack of metal tubes - overgrowing the inner diameter as the surface roughness of polyethylene are polmikrona. In addition, a special coating antidiffusion polyethylene pipe prevents the oxygen in the circulating water, and it protects against corrosion of all the internal systems of the house. Yet I must say that in some versions of plastic pipes provided a self-regulating heating cable, which can not lower the temperature of the fluid to the critical. The principle of operation of the cable based on the change of resistance of resistive material, depending on ambient temperature, so that special sensors and sophisticated automation here is not needed. Cable Protection of exterior problems of electrical networks should probably be given special attention. In most cases, electricity is supplied to the countryside homes through overhead power transmission lines that do not require insulation, seal and motor. Connecting individual homes to the mains by personnel power supply organization and the relationship with the landlord of this organization are determined by the "Regulations for Use of electric energy" and the agreement on the use of electrical energy. Sometimes, however, that on a plot of land laid electric cables, and that in this case, some protection is required. The supply cable must be laid, again, the representatives of the energy supplying organization, while laying the cable from the house to the other consumers professionals should provide for a range of protective measures. For the branches overhead power lines are allowed to use both isolated and non-insulated wires, the use of weatherproof insulation in this case, only recommended. But the cables in the ground should be isolated necessarily to avoid short circuit. To protect electrical cables from the cold, clear, does not make sense - the current flows through the wire and in the cold. But seal the power necessary because moisture leads to failure of power lines. Cable to the site lay within the desirable special pipes to protect against soil moisture grid. Cable entry to the premises carried out through the walls of insulated pipes so that water could not accumulate in the aisle and to penetrate inside. In order to fire passes to put in the walls made of flammable materials carried out in steel tubes. Entering the house - one of the most important nodes in the supply system, and it must be very securely seal the special seal, because the penetration of atmospheric moisture at the junction of the wires can cause short circuits.
