Mud Quality Control in Borehole Construction for Anti-Seepage Wall
The construction quality of anti-seepage wall has a direct impact on the operation safety of dams and reservoirs. Borehole construction is an important process in the anti-seepage wall technology, and mud is the key to stabilizing the trench walls during the drilling process. Mud also has functions such as protecting the walls, carrying debris, cooling and lubricating the cutting process. Therefore, it is important to pay attention to mud quality management during construction. By investigating the construction conditions on site, selecting a reasonable mud ratio, and strictly controlling the quality of the mud construction process, and verifying the mud ratio in the test section, it greatly improves the quality of the borehole construction of the anti-seepage wall in Beibaiyan auxiliary dam of Miyun Reservoir. This lays a practical foundation for future borehole construction projects and ensures the construction quality of the anti-seepage wall.
