The construction of urban underground comprehensive pipe gallery is an important part of urban infrastructure, and its waterproof performance directly affects the service life and safety of the pipe gallery. This paper discusses the selection and construction technology of waterproof materials in the construction of urban underground comprehensive pipe gallery, analyzes the performance characteristics and application scenarios of different waterproof materials, and puts forward the corresponding key points of construction technology. The research shows that the reasonable selection of waterproof materials and the strict control of the construction technology is the key to ensure the waterproof effect of the pipe corridor. By optimizing the waterproof material and construction technology, the waterproof performance of the pipe gallery can be effectively improved to provide a guarantee for the safe use of the urban underground space.
