REST IN PEACE
An historic cemetery in Washington, D.C., was the impetus for engineers to experiment with new chemical grouting techniques on a subway connection project. Construction of the Green Line, which passes beneath historic Rock Creek Cemetery, required chemical grouting for soil presupport. Contractors, though, were not permitted to drill from the surface, so an emerging drilling technology called horizontal directional drilling (HDD) with tube-a-manchette (TAM) grouting was employed. This article provides details on this unique drilling and grouting operation and notes some differences in the HDD/TAM method and conventional surface drilling and grouting operations.
