Abstract

PURPOSE: To obtain the packing with better water sealing capacity which can be used for the segment joint part, etc. to be employed in the shield method, etc. by charging the sealing material with excellent plasticity between the tongues of the elastic sealing material.
CONSTITUTION: The packing 1 is constituted of the frame body 3 of the elastic sealing material with four projected tongues on each of the top and back surfaces and the charging body 4 of the plastic sealing material to be charged between the tongues 2. The packing 1 is fitted in the groove 7 of each segment 6. The segments 6 are so arranged that the packing 1 are contacted to each other. By this constitution, the tongues 2 of the frame body 3 surface-contact to each other, and the charging body 4 charges the insufficient surface-contacting part to seal between the segments 6 completely. If the sealing is incomplete, the water swelling material mixed into the charging body 4 swells for the secondary water sealing.
