- Abstract:
- Aiming at the leakage phenomenon of drainage culvert due to construction quality problems, heavy transport vehicles and increased service life, the causes of leakage and the technical difficulties of grouting plugging were studied in combination with the engineering example of drainage culvert trenchless repair. The applicable grouting plugging methods, grouting plugging materials and pressures are summarized, which could provide reference for culvert repair under complex construction conditions and poor soil geological conditions.
