Kindergarten heating and ventilation

Management.

Construction is one of the main branches of the national economy of the country, ensuring the creation of new, expansion and reconstruction of existing fixed assets. Capital construction has a crucial role in the development of all sectors of production, increasing the productivity of public labor, raising material well-being and the cultural standard of living of the Soviet people.

One of the progressive methods of work is in-line, therefore, when laying the kindergarten heating network, all the necessary types of work are carried out according to three gripping systems. In order to determine the possible duration of the work, the parameters of the network are calculated, showing the accepted technology, while the total period was 15 days, which corresponds to the norm, and the maximum number of workers will be 11 people, which are obtained as a result of optimization based on a cyclogram for which the necessary structures are selected and placed on the construction site. As a result of using the proposed works, the cost of designing the works will be 17.29 thousand lei, the production reached 302.06 lei/h day, the cost of temporary farming will be 39,700 lei.

Construction organization technology.

Due to the ever-increasing needs of heat and gas, the construction of engineering networks is of great economic importance. The accelerated development of heat and gas networks requires a significant increase in the pace of their construction on an industrial basis with the complete mechanization of procurement processes. Only high quality construction of engineering networks and installation of equipment, advanced technology and organization of technical processes, as well as comprehensive mechanization of all labor-intensive works can ensure their durability, efficiency and usability.

This diploma project provides for the consolidation of theoretical knowledge in the field of earthworks for the construction of linearly extended earthworks and the installation of external heating and gas supply networks.

The purpose of the project is as follows:

- Assimilation of progressive technology of in-line method of works execution with application of complex method.

- Assimilation of composition and application of uniform norms and rates.

- Assimilation of composition and application of process normals for design of work at a separate facility.

The diploma project corresponds to modern technology and advanced methods of work.

The project uses in-line methods of work, industrial structures, as well as complex mechanization.

Operation flow chart of the work.

During the construction of the kindergarten heating system, to begin with, it is necessary to mark the places for laying pipelines, drill the necessary holes. The pipeline is then routed according to the design. To install radiators, it is necessary to produce templates using which brackets for radiators will be hung. After marking the installation places of brackets with a pistol, the brackets are nailed to the wall with dowel nails. After that, radiators are hung on the brackets. When the radiators are hanged, we begin to install submarines. The connectors to the radiator are attached on thread to the riser on welding. Isolation valves are installed on the system during the laying of mains and risers. Mayevsky cranes are installed after hanging radiators from the wall. The thermal assembly is mounted in parallel with all work and then connected to the heating system.

Scope.

This process sheet is designed for installation of district heating system in kindergarten for 160 seats. The designed heating system is horizontal with lower wiring. The heat supply system is centralized. Elevator unit is located in technical underground. Heating system highways are also located in the technical underground. Horizontal single-tube wiring with individual risers at elevation 0.000 and at elevation 3.300. The heating system is designed from bottom to bottom. Cast iron radiators reach the desired number of sections, in the mobile room of those workshops located on the territory of the construction site. Submarines are assembled according to a sketch at a production facility, then brought to the construction site by a cargo vehicle. Heating system mains are installed directly at the workplace, if complex parts are required, they are manufactured in the mobile store of those workshops. Heating system risers are also welded in place, if complex parts are required, they are manufactured as those workshops located on the site. Heating system lines are installed from pipelines of diameter 15, 20, 25, 32, 40, 50, risers are installed from diameters 15, 20. This paper presents a heating system with eleven risers. Risers St1, St3, St4, St5, St7, St11 are made of pipes with a diameter of 15mm. Risers St2, St6, St8, St9, St10 are made of pipes with a diameter of 20mm.
