A long pipe 15 positioned astride a number of the lower blocks 11 is laid in such a manner that the lower half peripheral part thereof is contained in the groove 21. A number of upper blocks 13 having a plurality of grooves 25 paralleling each other formed in an under surface are arranged in such a state that end faces are brought into abutment against each other with the upper half peripheral part of the pipe 15 covered with the grooves 25.
