Problems solved by technology

[0008] At present, the materials used in the existing non-excavation repair technology in China are: organic plastic materials, polyurethane waterproof materials, stainless steel sheet materials, and partial coating materials, all of which cannot be used for overall large-scale structural reinforcement and repair. The present situation of non-excavation repair technology of domestic drainage pipes. After years of research and development and experiments, our company invented a new type of reinforcement and repair material for urban drainage pipes and box culverts without excavation - box culvert polymer pressure injection material, which filled the town Blank of reinforcement and repair materials for drainage pipes and box culverts without excavation

Abstract

The invention discloses a novel city and town drainage pipeline and box culvert non-excavation structure reinforcement repair material-a box culvert polymer compression molding material, wherein a high-pressure pumping construction method is adopted to compress the box culvert polymer compression molding material into an underground closed die cavity equipped with rebars, to form an integral high-strength artificial stone structure, the structure bearing capacity is high; the structure stability, durability and integrality are excellent; the anti-permeability and the corrosion resistance are excellent; the drainage pipeline and the box culvert do not need to be excavated, and the operation does not interrupt the traffic, does not pollute the environment, does not disturb the residents, isshort in construction period, and saves capital; and therefore, the box culvert polymer compression molding material has broad market prospect and application popularization prospect.

Description

technical field [0001] The invention relates to a new type of reinforcement and repair material for non-excavation structures of urban drainage pipes and box culverts - box culvert polymer pressure injection material and its production process, belonging to the field of new materials. Background technique [0002] With the rapid development of urban construction, the construction of drainage pipes has increased year by year, and the scale of urban underground pipe networks has continued to expand. However, judging from the survey results on the construction and operation of drainage pipelines, in addition to the damage to the pipelines that have been in use for more than half a century since the founding of the People’s Republic of China, some newly-built pipelines also have structural and functional problems due to poor local geological conditions and other reasons. sexual damage. At the same time, the construction-in-progress affects or even damages the surrounding draina...
