CONCLUSION

Introduction

The course work is carried out in accordance with the task and represents sections of the work execution project during earthworks (vertical site layout with dimensions of 200x150 m and pit development with dimensions of 12x38 m).

Course design objectives:

To familiarize yourself with the procedure for development of work execution projects;

Select the main technological means and methods of execution of the specified types of construction processes;

develop skills in designing process diagrams of complex mechanized processes and performing feasibility calculations when substantiating accepted options for performing work.

Course work consists of an explanatory note and a graphic part. The explanatory note is made on 22 sheets of A4 format, the graphic part is developed on 1 sheet of A1 format.

Conclusion

In the course work, in accordance with the task, technological diagrams for the production of earthworks and construction and installation works were developed during the construction of the zero cycle of the building with dimensions in the axes of 38x12 m on the site with dimensions of 200x150 m.

To perform earthworks, the following machines were selected: DZ20 scraper, DZ17 bulldozer, D551A rink, E505 excavator. The operation diagrams of the machines are presented in the graphic part. The scraper performs movement according to the "zigzag" scheme. The pit is developed by an excavator for two penetrations. Cutting the vegetable layer is carried out by bulldozing strips 3970 mm wide in a trench way. The roller moves along a spiral-circular.
