A replaceable expansion joint leak prevention apparatus is provided to easily install and replace an expansion member by embedding a strut with fastening grooves on the sides of expansion space allowing water proof expansion members to be easily pushed in and out in. A replaceable expansion joint leak prevention apparatus comprises a pair of supporting struts(10) having fastening grooves to fasten expansion members(22) embedded on the sides of slabs; and a pair of fastening holders(20) having the same shape as the fastening grooves where the expansion members are coupled to by bolt nuts(21). The fastening holders coupled with the expansion members are pushed in to be fitted into the fastening grooves from one end of a bridge. The expansion members are made of rubber material and a reinforcing member is inserted into the expanding member. The fastening strut and the fastening holder are extrusion molded with aluminum material. |
