Abstract: In recent years, with the development of social economy and the rapid progress of science and technology,the construction of modern cities has gradually accelerated, and the number of municipal engineering constructions is increasing day by day, and urban construction is mainly carried out around the transformation of old cities.Since underground pipelines need to be laid during the reconstruction and expansion of the old city, in order to effectively reduce the difficulty of the entire project construction, reduce construction capital investment, and accelerate the construction progress, this article analyzes the construction process of the pipe gallery and pipe network in the municipal engineering construction in detail., In order to provide reference for related design.
