ABSTRACT:
The opening method to drill openings with required largeness on thick reinforced concrete walls such as a reinforced concrete dam body is presented.
This method comprises (1) the process of drilling cable penetrations in the depth direction on each corner around the opening domain on a reinforced concrete wall, (2) the process of penetrating cutting cable through cable penetrations and to carry out wire sawing with water injection, (3) the process to break and remove the separated core.
According to this method, the required opening for thick reinforced concrete walls such as a reinforced concrete dam body which has been regarded as difficult if not impossible, can be safely and exactly drilled with the smallest number of processes, having no bad influence on the surrounded wall.
