Comparison and Selection of Sewage Deep Tunnel Engineering Schemes Based on Value Engineering

Abstract

<p>In recent years, urban development, population expansion, and water pollution have become more and more serious. The main cause of reclaimed water pollution in Wuhan is that the combined drainage system is still retained, which makes the overflow pollution of the drainage system and the problem of regional waterlogging particularly prominent. The use of a sewage deep tunnel system to replace the traditional confluence system can basically eliminate overflow pollution. At the same time, applying value engineering to the decision-making stage of sewage deep tunnels for scheme comparison and optimizationcan effectively reduce costs, increase revenue, and enhance use functions.</p>
