ABSTRACT
Interface seal is the most important quality index of precast concrete culverts. The interface of prefabricated concrete square culvert is an important factor to form the quality of comprehensive pipeline gallery. The following points should be guaranteed: (1) the reliability of the sealing of the interface during the whole life of the pipeline; (2) the connection mode of prefabricated concrete square culvert should adapt to the requirements of construction technology and be simple and convenient; (3) the connection of prefabricated concrete square culvert should be convenient. In production and manufacture; (4) the connection mode of precast concrete culverts is simple and low cost. Therefore, the selection of appropriate interface treatment measures plays an important role in the later quality of underground comprehensive pipeline gallery. As a result, there are more structural joints, so strengthening the waterproof work is a very important content. Therefore, combined with the practice of a project, the application of waterproofing technology is analyzed.
