Summary: | This article is devoted to the generalization of production experience of concrete works by means of pneumatic concrete casting, which extends to the production of concrete works on the construction of residential, industrial buildings and other structures, their reconstruction and repair, as well as the manufacture of concrete structures in the factory. The paper considers the technology of production of works in concreting monolithic thin-walled concrete structures by means of pneumatic concrete casting. It is proved the advantages of the method of pneumatic concrete casting. The materials used and the selection of the concrete mix composition are described in detail. The methods of calculation for composition of the concrete mixture, the selection of equipment for the transportation of fine concrete mixtures and mortars, injection, primary and control injection are shown. The differences between pneumatic concrete casting and other methods of guniting are considered. All stages of the production process are described in detail. The article presents the operational characteristics of the installation "pneumatic concrete" for pneumatic concrete casting, in particular, the required amount of compressed air. The description of stages of pneumatic concrete casting is of interest. The issues of the work organization are considered, the service personnel and its duties are given. It is formulated the requirements of safety compliance at work. A detailed description of work technology opens up new opportunities for its improvement. This article will be useful for specialists engaged in the production of concrete works by means of pneumatic concrete casting. The article provides a detailed bibliography on the issue of pneumatic concrete casting, mechanization of production, technology of production of works. The normative documents used in the production of concrete works by the method of pneumatic concrete casting are given. |
