Técnicas de reabilitação sem abertura de vala de redes de drenagem de águas residuais

Abstract

O objectivo da presente dissertação consiste na apresentação de várias técnicas de reabilitação de redes de drenagem de águas residuais sem necessidade de abertura de vala. Para esse efeito efectuou-se um levantamento das técnicas de reabilitação de colectores sem abertura de vala actualmente existente no mercado, tendo-se identificado cinco técnicas diferentes, organizadas em dois grandes grupo: Técnicas de encamisamento (i.e., encamisamento pontual - «short liner» e contínuo com manga de fibras de feltro ou com manga de fibras de vidro) e técnicas de entubamento (i.e., entubamento simples - «sliplining» e com rebentamento por destruição da tubagem existente). As técnicas de reabilitação que foram desenvolvidas foram aplicadas a dois casos de estudo diferentes: um encamisamento contínuo com mangas de fibra de vidro (cura por radiação ultravioleta) para renovar o Emissário da Cadaveira, e um entubamento com rebentamento com tubos modelares pelo processo dinâmico, primeiro caso de entubamento realizado em Portugal para renovar um troço da rede de drenagem doméstica do novo Hospital de Cascais. A apresentação de casos de estudo foi fundamental para perceber o funcionamento das técnicas de reabilitação, e deu um aspecto técnico, essencial, a esta dissertação.

The aim of this present dissertation consists in the presentation of several rehabilitation techniques for collector network of residual water drainage without the need of ditch opening. For that purpose a survey of rehabilitation collector techniques without ditch opening was carried out. Five different techniques were identified and organized in to two mains groups: internal lining techniques (i.e., short liner and continuous) and relining techniques ( i.e. , sliplining and pipe – bursting). The art rehabilitation techniques developed were applied to two different cases of study: one continuous liner with glass fiber (cure for ultraviolet radiation) to rehabilitate the Emissary of the Cadaveira , and one pipe- bursting with modular pipes for the dynamic process , first case of relinning carried out in Portugal, to renew a section of the domestic drainage network of The new Cascais Hospital . The presentation of these case studies was very important to understand the functioning of the rehabilitation techniques, and gave a practical aspect, which is essential in this dissertation.
