Preparation of cast concrete sections with integral seals |
| 摘要 |
The method involves providing a mold with grooves (1) to hold the seals. The seals are held in place by a vacuum via lines connected to holes (4',4'') spaced along the grooves, The holes are fitted with sealing rings (3') for an improved grip on the sealing strips. The sealing strips have flanges which are embedded in the concrete.
