Determination of the actual excess excavation ratio (section “Kosino” - “Yugo-Vostochnaya”)
Ter-Martirosian A.Z., Kivliuk V.P., Isaev I.O., Shishkina V.V.

Abstract

Conducting tunneling construction at any depth causes deformations of the earth's surface and, as a result, additional movements of the surrounding buildings, as well as changes in the stress-strain state of the ground mass. When modeling the site of work to assess the impact of the construction of tunnels, it is necessary to take into account the volume loss of soil. The purpose of this work is to determine the technological parameter with further averaging and application in the design of dispersed soils. The article considers the impact on buildings from the construction of a two-track tunnel from the «Kosino» station to the «Yugo-Vostochnaya» station in Plaxis in a two-dimensional and three-dimensional with a design volume loss of soil of 1.5 %. The construction of the tunnels was carried out by a shield with earth pressure balance with a cutting diameter of 10.8 m. The maximum depth of the tunnel from the ground surface is about 27.0 m, the construction site is dominated by dispersed soils. For the considered section of the construction of the distillation tunnel, the calculated volume loss of soil for the two-dimensional problem varies in the range from 0.32 to 0.41 %, for the spatial problem - from 0.52 to 0.78 %. With the same additional draft of the building, there is a percentage increase from 62 to 90 % between the calculated parameters obtained in the schemes in both settings. Taking into account the calculated volume loss of soil at the design stage, obtained from the results of this article, in similar engineering and geological conditions, contributes to the rational distribution of funds, reducing the volume of geotechnical monitoring and measures for the preservation of buildings in compliance with the required standards and safety regulations.

Organizational and technical modeling of an integrated system of concrete work in the winter during the construction of residential buildings
Bidov T.K., Khubaev A.O., Shabanova A.A.

Abstract

The object of research is the production of concrete work in the winter. The goal is to develop a methodology for a comprehensive assessment of organizational and technological solutions for the production of concrete work during the construction of monolithic residential buildings in the winter. We reviewed the organizational and technical solutions for the production of concrete work in the winter during the construction of monolithic structures of residential buildings. We have analyzed the regulatory framework that governs the application of winter concreting methods. The production processes that affect the choice of a particular method are considered, indicating the advantages and disadvantages. Advantages and disadvantages of the basic methods of concreting in the winter were identified. The results of the analysis of the regulatory literature showed that today there are no clear recommendations on the design of concrete production technology in the winter, taking into account the features of the facility. There is no comprehensive approach to the formation of organizational and technological solutions within the framework of technological design. The results of the study will allow us to further create a methodology for choosing the most optimal organizational and technological solutions for the construction of monolithic residential buildings in the winter.

California Bearing Ratio of class F pond ash of various genesis
Lunev A.A., Iavinskii A.V.

Abstract

To study the bearing capacity of pond ash, samples were taken from dumps of a number of power plants in the Russian Federation: Omsk TPP-4, Novocherkasskaya TPP, Serovskaya TPP, Apatitskaya TPP, producing pond of various genesis. All studied materials classified to class F according to ASTM C-618-12. At the first stage of the study, the maximum dry density of soil and the optimum moisture content were determined by the Proctor method (type B mold and type A compaction hammer), the results of which were compared with the results of determining the same parameters by the SoyuzDorNII method (using a large standard compaction device). At the second stage, the Californian bearing ratio (CBR) of all samples of pond ash in a water-unsaturated state at different densities was determined (corresponding to compaction 7, 21 and 56 by blows of a compaction hammer on a layer of pond ash in the a Proctor mold). At the third stage of the study, the deformation modulus of pond ash were determined on samples with optimal moisture content and maximum dry density of soil by the method of oedometer test. Samples were prepared with the using a large standard compaction device of the SoyuzDorNII design. At the end of the study, the results were analyzed and conclusions were drawn about the linear relationship of the parameters (optimal moisture content and maximum dry density) determined by the method of Proctor and SoyuzDorNII, the presence of a correlation between CBR and the compaction coefficient of the PA, and the absence of a statistically significant correlation ( R 2 <10 %) between CBR and deformation modulus in the study of PA of various genesis.

Mobile pneumatic transporter for snow and garbage removal from roofs and house areas
Muratova V.A., Funtyaeva V.V., Zverev O.M.

Abstract

Snow removal from roofs and near-house territories is relevant for the Perm Territory in the winter. The article discusses a mobile pneumatic transporter for garbage and snow removal consisting of a fan, a loading bin, an ejector chamber, and a vibrator. The main novelty of the plant is the use of polyethylene film for transport ducts. Air ducts were made by soldering with a hot iron. In the suture allowances, sutures were made to hang air ducts on a cable when removing snow from the roof. The calculation of the ejection funnel for the fan FS-2101/SP 220D is given in the work. As the funnel body, a plumbing two-rib tee with a diameter of 150 mm was used, in which a confuser of Æ100 mm was made. Since there is no data in the literature on the coefficient of friction of polyethylene, measurements of the total pressure losses in the system from the funnel to the final point of unloading, the dependence of the air flow rate and the suction rate from the loading hopper were made on the forty-meter air duct. After the calculations, a mixing chamber with a diameter of 125 mm was added to the tee. The pneumatic transporter demonstrated the ability to move snow to a distance of 40 meters at a speed of 10 m/s. Snow capacity is 9 cubic meters per hour. When removing snow from the roof along the air duct suspended with a slope of 1: 4, the snow can slide without the fan turned on. The pneumatic transporter can be used as a loader to a height of at least 4 m. The advantage of our pneumatic transporter over snowplows is the electric fan drive. This allows you to store the installation in the utility rooms of a residential building, without violating fire safety. The film ducts are compactly folded into a storage roll.

The relevance of the issues of training specialists in geotechnical construction
Polishchuk A.I., Demchenko V.A.

Abstract

Due to the high rate of development of new territories for construction, which often turn out to be difficult in engineering and geological terms, the need for geotechnical construction specialists (geotechnical specialists) is growing. There are practically no specialized educational programs for their preparation in Russia. The formation of specialists for geotechnical construction enterprises is mainly made up of university graduates and employees of the construction industry. In rare cases, there is a re-qualification of specialists from related engineering or scientific activities. Technological progress and introduction of computers significantly contribute to the complexity of engineering solutions, and at the same time increase the requirements for geotechnical specialists. In 2017, in accordance with the order of the Ministry of Labor and Social Protection, the professional standard 16.131 "Specialist in the design of foundations, foundations, earth and landslide structures, the underground part of capital construction projects" was approved. The standard regulates the labor functions, knowledge, and skills that a geotechnical construction worker must possess. The existence of the standard and the requirements given in it create the need to form a systematic approach to solving the problems of training geotechnical specialists. One of the possible system approaches can be developed on the basis of additional professional education. The training should be carried out both on the basis of advanced training programs and on the basis of professional retraining programs. In general, this will improve the quality of education through the development of specialized educational programs for geotechnical construction specialists.

Polishchuk A.I., Chernyavskii D.A., Gumenyuk V.V., Solonov G.G.

Abstract

The main reasons for the appearance of underground and atmospheric water in the basements of the school building, which has been in operation for more than two years since its commissioning, are considered. The building is three-story, brick, with a basement and attic roof. The building foundation is made in the form of two monolithic reinforced concrete slabs arranged at different elevations (in height) and separated by a deformation joint. Geodetic survey data indicate that the site of the building is located in the lowest part of the courtyard. The engineering and geological structure and hydrogeological features of the construction site, as well as the state of the relief and structural solutions of the yard structures are analyzed. The results of the survey of building structures, observations of the position of the ground water level at the base of the building and atmospheric waters on the courtyard territory are given. Based on the results of the survey, assessment of the ground conditions of construction, observations of the hydrogeological regime, the main reasons for the appearance of underground and atmospheric water in the basement of the operated building were established in the base.
