ROMEO ARM OF THE MACOMB SEWER INTERCEPTOR Janauary 14, 2005 Update Crews have finished installing all 228 caissons in the sinkhole around the repair area. The caissons were installed to a depth of 65-feet to stabilize the area. Crews are continuing the excavation of the interceptor. So far, 140-feet of the interceptor has been exposed. Crews have placed 50-feet of concrete mudmat in preparation for replacing the first sections of the interceptor. The first section (8-feet long, 11-feet in diameter) has been placed in the trench at the east end of the repair area. Crews will continue with replacement sections moving westward along 15 Mile Road. To replace the damaged portion of the interceptor, crews must remove the top portion of the collapsed interceptor and place a concrete mudmat on top of what’s left of the collapsed section. Once the mudmat is in place, holes will be drilled down into the remaining interceptor. Grouting will be inserted to totally fill every cavity left in the damaged section, forming a solid support base. Next, a steel and concrete cradle will be installed on top of the mudmat to support the new pipe being installed.
