Dimensionamento e execução de torre metálica para a sustentação de quatro depósitos de água de 10 000 litros

Abstract

This document refers to the professional internship report carried out at the company GEODRILL, LDA – Surveys and Geotechnical Works, located at Av. 25th of September, nº 2526, 1st floor-City of Maputo. This internship is part of the plan current curriculum at the Faculty of Engineering of the Eduardo Mondlane University as a form of completion of the course to obtain the degree of licentiate in Civil Engineering. This report presents the design and execution of a tower metal to support four water tanks of 10 m3 each, of approximately 15.60 m high at the base of the deposits for the Water Supply to Vila de Mopeia - Zambézia Province. The metallic structure is basically composed of two parts: the platform, which is the base that receives the water tanks, consisting of metal grids, main beams and secondary in profiles I and the support base of the platform forming a truss and materialized by angles with equal flaps. The connections between the different elements are carried out by screws making their assembly simple and quick when compared to welds. The manufacturing process comprises two phases: cutting and drilling based on the execution drawings. As a structure with bolted connections there is a need to carry out pre-assembly on the shipyard in order to verify the hole compatibility and adjust it if necessary, as well as the marking of parts and their positions which facilitates the assembly process. Assembly consists of positioning and fixing the parts in their respective places. building. This process was carried out using a roller system. It was not possible to present the complete execution of the tower due to difficulties found in the place, that is, the alteration of the place previously indicated for the implantation of the structure and the weather conditions, which led to the extension of the period of execution of the work (TRADUÇÃO NOSSA).
