Execução de laje subpressão: análise de metodologia baseada em estudo de caso

Abstract

Motivated by the growth of civil constructions in João Pessoas’s waterfront and the restraint of height in the region, the Search by biered structures, like underground and lower reservoir, increased significantly in beach regions. For hitting the groudwater, these structures require especifics techiques and Technologies to resist the water and soil effort, making the subpressure slab one of the solutions. For bieng a complex structure and require a well done execution, it was decided to analyze the literature about this process, from the previous steps, like excavation and containment, to de concreting process with the objective of build a theoretical base. For complemente this, the present paper consists in a study of case of a subpression slab localizated in a coastal district of the city of João Pessoa, listing the main decisions making that resulted in success and the critical points observed. With the theorical and practice bases, it was possible to elaborate a executive script to ensure tightness of the structures and avoid emergence of unforeseen events during the execution due lacks in the planning and restoration and maintenance costs in cases that the process wasn’t done properly.
