for snow removal from roads used by different snow-clearing equipment. The efficiency of its use is determined by the road conditions. This is especially true for snow plows in settlements with elements of arrangement of road (curbs, sidewalks, road barriers, stopping points). In these circumstances widespread machine dumps. The ability to develop, manufacture and operation of dumps of snow plows on small and medium-sized enterprises defines their widespread use and a variety of designs. Promising to modernize the necessary conditions under heaps of snow removal from roads and sidewalks. The decision in this case take into account the comprehensive approach, comprising as an account of the influence of external factors - the operating conditions of the machine, and internal changes in the parameters of the machine. Analysis of the problem has allowed to hypothesize on the design of blade snow removal machines. In order to develop a scheme blade methodology for the study and design of experiments, the basic factors of influence on the resistance. The design blade for snowplows and virtual model to assess performance.

The calculation of technological and economic losses caused by emission of electrolysis hydrogen in the atmosphere is made. The flow of oxygen and air during the combustion gases and the amount of simple combustion is calculated. The ways of economically viable utilization of associated hydrogen would increase the level of environmental safety of the process are revealed. We consider the use of hydrogen produced during electrolysis of sodium hypochlorite solution to produce hot water for the needs of the enterprise. Proposes the use of snow in the territory of the water supply enterprise as a backup element for the implementation of resource-saving technologies for potable water.

The article summarizes the purification schemes of roads from snow and used in this machine. Depending on the various possible ways and means of snow removal. In the majority of methods used machines with blade. The analysis of dumps of snow plows and the tendencies of development of the working bodies. Promising to modernize dumps under the conditions necessary snow removal from roads and sidewalks, stopping pockets that are height above the roads. The decision in this case take into account the general trends of development of designs dumps. The most important of which is to increase the mobility of the blade and its division into elements. The use of hydraulic drive allows to simplify the structure of the working body of a snowplow. The effect of the implementation of research results is determined by reducing the number of passes and the number of snow plows used machinery

The investigation and analysis of noise characteristics of the traffic flow via a directional microphone. The principle of operation of directional microphones and test procedures. Full-scale research made microphone-controlled lane highway. When approaching the vehicle to the maximum level of the microphone signal is necessary at the time of finding the vehicle in front of a microphone. Investigations at the location detection hole up from the road surface to the left (toward the oncoming lane controlled by car) and right (after moving band controlled by car). Location detecting holes toward the oncoming lane controlled by car is the best, as it allows to ensure minimum impact on the accuracy of counting cars traveling on the adjacent oncoming lane.

The article discusses the relevance of the compact, mobile radio modem sup-ports modern interface USB. The result is the development of a half-duplex tran-sceiver is a device that works with a frequency manipulated signal in a license-free frequency band. The radio modem is equipped with interface USB, through which data is exchanged, as well as its food, as antennas used inefficient quarter-vibrators. Increase in radio range is possible by the use of antennas with high directive gain. Experimental studies of two designed devices were carried out in an urban setting. Their aim was to establish the maximum sustainable radio range (with line of sight) at different data rates as error correction at the reception, and without. Experimenter, away from the transmitting radio modem, monitored the received data. The use of error-correcting coding is most effective at high data rates (up to 3 dB) than at low (1-2 dB). Increase in radio range is possible by reducing the transmission speed - this is due to the dependence of the receiver sensitivity of the speed manipulation. It should also be noted that the decrease in device size is possible by structural modification.

There are many classifications of geodetic networks State geodetic network (hereinafter referred to as SCS) is based on a geometric plan, high-altitude (nivelirnye) and the spatial geodetic network. One of the main goals of building PCS is secret orienteering within the territory of the country. Classified data are a topographical plans, maps, aerial photographs, with great accuracy to identify the purpose or location of any object. Because of the wide use of PCS, ensuring their secrecy is produced in a variety of ways. In the construction industry before hitting the construction plans and maps staff, surveyors are retracted to plan all the framework design, which contains all the coordinates and used reference systems.

Implemented assessment of the mechanical behavior of reinforced synthetic fibers of polyethylene pipes, which are provided in the construction adhesive layer connecting the reinforcing plastic shells and pipes. Presents the results of quasistatic tests the tensile strength of model samples in the range of low climatic temperature and speed tests 25-100mm/min. The dependence of the temperature of ductile-brittle transition in the mechanism of destruction of model samples of speed tests, which at 100 mm/min up to 0°С. The mechanism of destruction of a model sample of the reinforced polyethylene pipe, consisting in cracking of the technological layer connected with layers of PE80 which ability to braking of a crack and defines transition from viscous destruction to fragile at fall of temperature of tests is interpreted. It appears that this result emphasizes the need to further clarify and harmonize the existing regulatory requirements on the use and operation of pipes and polyethylene pipelines in cold climate regions.

An analysis of snowplows in urban environments. Determined that the efficiency of snow removal from roads, sidewalks areas affected humps (bumps), borders, etc. In line with this analysis of structures working bodies (dumps), used in Russia and abroad, as well as analysis of patents. In accordance with the foregoing, all decisions on the management of blade can be divided: extra lever systems; modernization of hydraulic drive; use microprocessors; the combination of these approaches. Obviously, the use of processor technology is justified for high-tech machines, as a consequence has disadvantages in price, qualification of operators and maintenance personnel. For the modernization of existing equipment, at the moment, it is advisable to use the combined system using the lever and hydraulic drive systems. It is necessary to take into account the energy-saving technologies.
