Ligação laje-parede em reservatórios hidráulicos retangulares de concreto armado: visão de uma construtora do município de Pato Branco - PR

Abstract

Reinforced concrete hydraulic reservoirs play a crucial role in sanitation infrastructure, being used for both potable water supply and wastewater treatment. The connection between the slab and the wall in these structures is a critical aspect, as it directly influences the reservoir’s strength, watertightness, and durability. This exploratory qualitative research focuses on analyzing the slab-wall connection in rectangular reinforced concrete reservoirs from the perspective of a construction company with over 20 years of experience, based in Pato Branco, Paraná. The company specializes in reinforced concrete and infrastructure works, with a strong presence in the sanitation, energy, and special projects sectors. The study adopts an approach that includes the analysis of projects provided by the company and the collection of information through a semi-structured interview in the form of a roundtable discussion with an engineer representing the company, considering normative, structural, and executive criteria. The research examines the solution adopted by the company, which includes the use of corbels combined with monolithic concreting and construction joints, highlighting their advantages, disadvantages, and challenges in the execution process. Additionally, the study explores the influence of maintenance on structural integrity, emphasizing the need for proper planning to prevent failures and ensure the structure's durability. The results indicate that the choice of connection method must balance structural safety, ease of execution, and cost-effectiveness, aligning with regulatory guidelines and best engineering practices. The research reinforces the importance of modernizing construction processes and adopting solutions that enhance efficiency in the construction of reinforced concrete reservoirs.
