Abstract
PURPOSE: To discharge drain through a communication member to the outside from a rubber dam where drain is all stored by providing the communication member whose one end is positioned in the rubber dam and the other is outside of the rubber dam.
CONSTITUTION: An intorduction pipe 4 to be inserted into a rubber dam 1 is opened inside the rubber dam 1 at its one end, and also buried in the slope of a river bank at the other end in such a way as to open the other end outside of the rubber dam 1. A weight 6 is provided to one end of a hose 3 to be inserted into the rubber dam 1, and a valve 5 is provided to the other end. The rubber dam 1 is erected by sending a fluid, e.g., compressed air, into its inside through an air supply and discharge pipe 2, whereupon drain stored at the bottom of the rubber dam 1 is discharged to the outside through the hose 3 according to the internal pressure of the rubber dam when the valve 5 provided at the end of the hose 3 is opened.
