ABSTRACT:
A wet connection method for the precast concrete units capable of performing the connection of the units in a shorter time by electrically heating the concrete placed in the connection part. This method comprises the steps of connecting the reinforcing bars of the units to each other with a second conductive member of a conductive wire or net member in a space defined by the reinforcing bars, winding a conductive liner member around the connected reinforcing bars in order to provide a first conductive member, electrically connecting terminals of an electric power source to the first and second conductive members in such a manner that the polarities of the terminal and the conductive member are opposite to each other and applying electric power to the conductive members in order to cause the concrete placed in the connection part to be heated and rapidly cured. The present connection method shortens the curing time of the concrete and the term of work.
