Abstract: Comprehensive pipe gallery is a new type of pipe gallery burying facility engineering technology that has emerged in the fi eld of municipal engineering construction in recent years, and has been vigorously promoted in the construction of municipal engineering projects across the country. Based on this, this article focuses on the analysis of the construction process of the integrated pipe gallery in the tropical rainy season, combined with BIM technology to carry out a three-dimensional simulation of the key construction control links, in order to provide theoretical guidance for related project organizers.
