ようにするのが好ましい。It is desirable that the size of each groove of the U-shaped sealing members 1 and 2 be as small as possible as long as the above conditions are satisfied. It is preferable that the ends of the sheaths 4 and 5 are slightly inside the joint surfaces of the precast concrete members 3 and 4.

モルタルが入らない。When the joint surfaces of the precast concrete members 3 and 4 to which the U-shaped sealing materials 1 and 2 are respectively attached are opposed to each other with a predetermined joint gap therebetween, the side wall and the bottom of the U-shaped sealing material 1 Each flat surface of the wall portion, the side wall portion of the U-shaped sealing material 2 and each arc surface of the bottom wall portion are elastically closely contacted with each other. When the filler 9 is filled, the mortar does not enter the grooves of the U-shaped sealing materials 1 and 2.
