What Are the Different Types of Drainage Repair?

Drainage management is the correct use and maintenance of the completed drainage system in order to give full play to its engineering benefits.

Drainage management

For areas where groundwater levels are too high and threatened by waterlogging and secondary salinization, an observation well network should be arranged to regularly monitor changes in groundwater levels and salinity. Water measuring equipment is installed at the entrance and exit of the open ditch to regularly measure the flow and water quality in the ditch. According to the observed groundwater level and water quality data, drainage flow, irrigation water volume and rainfall, etc.,

Drainage management agencies shall formulate maintenance and maintenance plans for the project every year, repair, clear silt, and weed the drainage ditch at all levels, and formulate major repair plans every three or five years according to the actual situation. Completely repair buildings or trenches that are severely damaged. The key points of maintenance and maintenance of open trenches are to prevent rainwater from eroding the slopes of the trenches, especially to prevent collapse and landslides. The collapsed slopes must be cleaned and repaired in a timely manner, and weeds and silts in the trenches are often removed to maintain the drainage Design over water capacity; regularly check the opening and closing equipment of the drainage culvert, and do rust prevention and maintenance work to prevent operation failure. The key to the management and maintenance of the underdrain drainage system is to constantly check the water flow of the pipeline to prevent collapse and silting. Desilting and maintenance measures should be taken for the silted or collapsed pipe section, and excavation should be carried out for complete renovation. Cover observation wells to prevent blockage. When an abnormal level of the observed water level is found, the cause must be found and repaired in time.
