This article describes the territories of the northern regions of the Russian Federation, the problems of the distribution of permafrost soils (MMG), and discusses the difficulties encountered in the construction of roads in difficult geocryological conditions. The introduction of heat-insulating layers of foam glass rubble into the design of pavement is proposed. The basic physical and technical characteristics have been analyzed, and the key properties of foam glass rubble are determined. The article describes the process of production of foam glass, the advantages that allow the use of this material in various fields of construction. Typical road structures made of soil are considered. A comparison is made of a typical construction of pavement made traditionally from soil (high embankment) with a construction with a heat-insulating layer of foam-glass rubble. The advantages have been listed when using structures using foam glass rubble in road construction.

This article is the result of a study of project documentation, one of the largest oil companies in the Russian Federation. This article aims to identify and identify systematic errors and deficiencies in the design of oil fields, which can lead to significant risks of accidents, damage to equipment, violation of the integrity of buildings, the emergence of threats to human life. The aim of the author was to identify and systematize these shortcomings, to offer the best options for correction for the purpose of further application, qualitative improvement and acceleration of the design of oil fields. Further examples of errors and shortcomings of project documentation, expected consequences which can occur if not to eliminate these errors and all necessary normative base on these questions will be given. Errors at the design stage, in turn, can lead to disastrous consequences, ranging from increased construction time, ending with emergencies and irreparable damage to the environment and human health, which leads to enormous economic losses. Design errors, even the most insignificant, can be compared with the butterfly effect. A minor mistake in the project can lead to grandiose consequences. Ballasting of pipelines. Ballasting of pipelines is taken into account in the installation of pipelines through water obstacles or water-bearing sections, when laying in the swamp.Depth of laying of pipelines at crossing of water barriers. The development of design solutions in the field of transitions on the materials of surveys that were carried out more than two years ago, without the implementation of actual engineering surveys is not allowed.Electrochemical protection of pipelines. At all available ways of laying, (except above-ground), irrespective of degree of aggressiveness of soil, pipelines shall be protected by complex anticorrosive substances and means of electrochemical protection are applied.The location of the purge of candles on the pipelines. The distance from a certain point to the purge plug in the construction of main pipelines from overhead wires must be taken from 300 meters, under cramped conditions of the route of high-voltage overhead lines, this distance can be reduced to 150 meters.the aim of the study was to identify design errors and their consequences, with the aim of further prevention and accounting. The result of these adjustments and corrections will be both cost savings and reduced construction time

The development of modern technology makes increasingly stringent requirements for materials, and improving the reliability and durability is an urgent task for many industries. One of the most important elements of the automatic coupling device of the car is the absorbing device. The parts included in it must meet high standards, be reliable and provide the necessary hardness and mechanical properties of the materials throughout the life cycle of the car. One of these parts included in the friction unit of the absorbing device is a movable plate. In the present work, an example of modernization of the absorbing apparatus through the use of modern methods of modeling and manufacturing of a fixed plate is given. The technical result is to reduce consumption of materials of the movable plate, and to simplify the manufacturing process of the plate by making it from rolled steel.

Over the last years there is much concern about the quality of execution and selection of the actual documentation in the registration proceeding of the facilities construction turn-over package. There is no exact consolidated catalog of as-built documentation in the new normative and technical literature. Each executive document represents as an application to various sources of regulatory and technical literature. Therefore, the article presents a divided into chapters detailed catalog of as-built documentation for the oil and gas facility construction. An explanation is given for each chapter for which purpose it is formed and what function it has in the general package of as-built documentation. The main aspects of the as-built documentation execution are considered, a list of the documentation and some recommendations on the facility commissioning to the Client are given. Additionally, there is a suggested recommendation on the execution and filling of the package (folders) of the construction as-built documentation. This article recommends a common procedure for filling out and arrangement of the document flow of PTW package and as-built documentation of construction and installation works and the commissioning of the capital construction facilities.
