The present invention relates to the improvement of a connector for connecting a drain board type drainer used for a groundwater drain boost method for the soft ground by using a vertical drain method in a ground improvement method for stabilizing the soft ground. The drainer connector has an expansion part at the bottom to be expanded and a sealing ring to be inserted into a space between an insertion hole inside the expansion part and the outer side of a drain board. An L-shaped opening is formed by removing a part on the front side of the bottom in one side of the expansion part. Therefore, the coupling of the drain board can be facilitated. |
