Squaring off and reaming tool for deep elongated trench excavations

Abstract

There is disclosed a tool for squaring off and reaming the walls of an elongated trench excavation which has been previously formed utilizing the slurry trench excavation method. The tool is constituted by a pair of spaced parallel steel beams which are connected and maintained in their space relation by a plurality of connecting steel lattice bars. The lower edges of the beams and the lower connecting lattice bars have cutting and smoothing edges formed thereon for smoothing and squaring the walls of the elongated excavation. The tool may be left in the last excavation of a series and serve as the connected H-beam pair as disclosed in the article appearing in the October, 1973 issue of Roads and Streets Magazine entitled "Slurry Wall, Special Equipment Solved `No Room` Excavation Problem".
