Visible damage to the appearance
Cracks
When cracks appear on the surface of concrete hose, regardless of the size of the cracks, close attention should be paid. Smaller cracks may gradually expand, affecting the structural stability and sealing of the pipe. If the crack width exceeds a certain limit, or the number of cracks is large and the distribution is wide, it needs to be replaced in time.
Peeling
Peeling on the surface of the concrete pipe indicates that the bonding strength of the concrete has decreased. It may affect the durability and normal use of the pipe. At this time, the peeling parts need to be repaired to prevent the problem from getting worse.
Problems at the interface
Leakage
Leakage at the interface is a common problem. This not only leads to waste of resources, but also may cause damage to the surrounding soil and buildings. If leakage is found, the interface needs to be repaired, resealed or the sealing material replaced.
Loose or misaligned interface loose or misaligned will affect the connection tightness and overall stability of the pipeline. When the inspection finds that the interface is obviously loose or misaligned, it should be adjusted and repaired in time. Ensure that the interface is firmly connected.
