Abstract [eng] |
Foundation is one of the most important structures of a building, it regards the durability of the building and the price of construction. Pile foundation is one of the oldest and most widely used types of foundation, which differ in their form (cylindrical, rectangle and others) and materiality (wooden, metal, reinforced concrete). Foundation of this type can be installed not only in all kinds of buildings, but also in roads, bridges and etc. In this project I will analyse the most widely used type of piles – piles of reinforced concrete. There are three types of these piles: bores (after drilling a borehole of needed depth and diameter, a metal frame is inserted and the borehole is filled with concrete), forgings (already made pile of reinforced concrete is brought and hammered in the primer), CFA (piles of continuous flight auger, when concrete is being sprayed while drilling and a metal frame is inserted afterwards). The most optimal and suitable type of installation of pile foundation for each primer is being calcullated using TOPSIS method. The calculation criterion of the method I selected by myself, the importance of the criteria was evaluated by people working at projection sphere whom I have questioned. I will compare the diameters of foundations, their depth, the price of installation, the price of materials used to produce a pile, the amount of mechanisms used for installation and the speed of installation. After evaluating the results, for the first and the third type of primer the most suitable foundation is bored foundation, for the second type of primer – forged foundation. After evaluating the calculation of chosen criteria and summing up the results it can be stated that optimal way of installing pile foundation is forging pile foundation. |
