Corrugated culvert construction site should be what matters needing attention：

1. Strictly control the raw material quality of the outlet Corrugated culvert.

The Corrugated culvert entering the site shall be piled up neatly, and workers shall not tread on the Corrugated culvert.

2. Corrugated culvert to cover maintenance, to avoid wind and rain to make it early aging.

3. The Corrugated culvert should be cut straight, and it is forbidden to cut into inclined mouth.

4. Corrugated culvert joint method: corrugated culvert joint to outsource 0.3 meters long large Corrugated culvert and the two ends to be tightened in half, the center shall not leave open space.In order to ensure that there is no open space in the center, symbols should be made at the ends of the two joints.

After doing it, wrap it tightly with tape to prevent slurry leakage.

5. The orientation of the Corrugated culvert should be accurate, especially the part close to the joint. The distance of the positioning steel bar of the Corrugated culvert should be 0.5 meters, which should not be lacking.

6. When the welded steel bar is close to the Corrugated culvert, measures should be adopted to maintain the Corrugated culvert from being burned. If you do not take care of the burn, the burn should be wrapped tightly with adhesive tape.

7. Considering that the number of corrugated culverts on the roof is gradually reduced, any parts that conflict with the corrugated culverts should avoid the Corrugated culvert.

8. When pouring concrete, it is forbidden to put material towards the corrugated culvert.

The vibrating rod shall not collide with the Corrugated culvert and shall not vibrate between two vibrating rods and a Corrugated culvert.

Especially when the web vibrating, it is forbidden to vibrate the vibrator in the same direction for a long time, and the vibrating time is not more than 20 seconds.

9. Pay attention to maintain the leaky Corrugated culvert at the end of the mould when dismantling.

10. for the steel strand maintenance method: into the scene of the steel strand to cover up, to avoid rain, the ground to pad the square wood to separate from the ground, the steel strand to participate in the first use, after the participation of the use, can not keep the time is too long.

11. If the above situations are found, they should be corrected immediately, otherwise the next process will not be constructed.
