To provide a seal material for grouting between a pile and a sheath pipe, which is capable of making an injection space of a grout material dry, facilitating management of the grout material, and facilitating construction without the need of applying a large load for attachment.
A seal material 10 comprises: a fixed base part 11 formed in a cylindrical shape along an inner periphery of the sheath pipe and attached to the sheath pipe; a grout material seal part 12 extended diagonally upwards in a center direction from the fixed base part 11, whose distal end is formed with a diameter smaller than a pile outer diameter and is brought into contact with a pile outer periphery to seal the grout material; and a dry state seal part 13, which is extended diagonally downwards in the center direction from the fixed base part 11 and whose distal end is formed with the diameter smaller than the pile outer diameter and is brought into contact with the pile outer periphery to seal the upper part thereof in the dry state. Thus, even by the seal material of an integrated structure, reservation of the dry state and sealing of the grout material are separately performed in the respective seal parts.
