The maintenance of steel corrugated culverts mainly includes the following aspects:
Regular cleaning: Regularly clean the debris and dirt inside and outside the culvert. You can use a high-pressure water gun or special cleaning tools to remove the mud, leaves, garbage, etc. attached to the surface of the culvert to keep the culvert unobstructed and neat in appearance.
Check the connection parts: Pay attention to check the connection parts of the culvert to ensure whether the bolts are loose and whether the seal is good. Steel corrugated culverts are made of steel plates and are prone to damage such as rust, corrosion and deformation. Therefore, special attention should be paid to these details during maintenance.
Prevent corrosion: Prevent the corrugated pipe from contacting corrosive substances such as chemicals and water vapor, and avoid being in a humid, high temperature, high pressure and other environments for a long time. Regular cleaning and anti-corrosion treatment of the corrugated pipe can effectively extend its service life.
Control the frequency of use: Reduce the number of bending and expansion of the corrugated pipe to avoid fatigue caused by frequent operation. At the same time, avoid the impact and extrusion of the bellows by external forces, strictly control the parameters such as temperature and pressure, and avoid exceeding its tolerance range.
Regular replacement: The service life of the bellows is limited. Once the bellows are found to have problems, they should be replaced in time to avoid potential safety hazards.
Other maintenance measures: During installation and use, it is necessary to strictly follow the relevant standards and requirements to avoid excessive bending and stretching. When performing other construction operations, such as electric welding, the bellows should be effectively protected to prevent welding slag from splashing the bellows.
