Resin Manhole Cover Daily Maintenance Inspection Attention Product

It is important to use the daily maintenance of the resin manhole cover. So what should you pay attention to in the daily maintenance inspection of the resin manhole cover?
1. Appearance monitoring: The surface of the manhole cover is neat, smooth and free of cracks. The pattern is clear and the handwriting is clear.
2. Base detection: appearance: no obvious welding defects. The diameter of the well circle is detected by a maintenance tool. The diameter of the control range is 40 mm in the size of the manhole cover. The bolt holes of the anchor bolts must be inspected with special type inspection tools.
3. Coordination and spray detection: The T-shaped rubber ring is matched with the well ring. The rubber ring is placed in the T-shaped groove to be flat, not long or short, and the bonding is firm, and the matching clearance is not more than 1 mm. The manhole cover and the well frame are assembled in a flat manner, without shaking or sounding, and the height of the cover and the frame does not exceed 1 mm. The T-shaped rubber ring is first sturdy and then sprayed, and the water well cover (ring) is sprayed evenly and without rust. In the well seat of the sewage inspection well, the T-seal strip is placed in the inner ring groove to form a silicone ring, which prevents the running, jumping and ringing of the inspection manhole cover, and increases the manhole cover and the inner ring mouth. The area of ​​the contact and the stapler is increased, thereby avoiding the running, jumping and ringing of the manhole cover.
