When the linear drainage ditch is completed, its performance and accessories need to be reviewed and can only be put into service after meeting the requirements. So, what criteria do we have in acceptance?


1. Check whether the surface of groove cover plate is flat and recheck the appearance quality.


2. The bearing capacity of the linear drainage system must meet the bearing capacity requirements specified in the design.


3. Check sludge in drainage ditch to ensure smooth drainage and smooth inner wall of drainage ditch.


When the project is finished, we need to acceptance according to the standard, so as to guarantee the later use effect.
