With the rapid development of engineering construction technology, compared with cast-in-place construction, the assembled culvert sections are manufactured and maintained in a centralized manner in a factory without being influenced by external environment and climate, and the quality of the culvert sections can be effectively controlled; the manufacturing of the prefabricated part and the work of foundation treatment and foundation treatment on a construction site can be carried out simultaneously without mutual interference, so that the construction period can be greatly shortened; by adopting the modular prefabrication and assembly construction method, the standardized construction level is improved, resources are saved, the pollution of construction to the environment is reduced, the labor production efficiency and the quality safety level are improved, and the construction cost is reduced. For the waterproof structure of the assembled culvert section, a waterproof layer is coated on the surface layer of the joint or a waterproof cover plate is covered on the surface layer of the joint for waterproofing, and meanwhile, various embedded waterproof structures are prepared. However, the waterproof structure cannot fundamentally avoid the hidden trouble of water leakage, and particularly, when the foundation is weak or uneven in hardness, the two sides of the seam of the culvert section inevitably generate relative displacement, so that the waterproof structure is still seriously influenced to form the hidden trouble of water leakage. Once leakage occurs, the underground water is enriched in the foundation soil around the culvert sections and under the culvert sections, the deformation of the foundation soil is increased, and the stability of the roadbed is seriously threatened.
