It took a man of genius to recognize that a different sort of machine was needed—a machine that could both prevent the roof and walls from collapsing and hold back any quicksand or water at the tunnel face. The chief engineer of this first tunnel project was a muscular giant named Richard Trevithick, a self-educated man who had progressed from youthful fame as a Cornish wrestler by displaying a dazzling talent for invention. The frames were divided into 36 cells, each three feet wide and almost seven feet tall, and arranged one atop another on three levels. No engineers had tunneled under a major river, and the Thames was an especially tricky river. Today, engineers deal with treacherous ground by pressurizing their workfaces (though that solution still leaves tunnelers vulnerable to the problems that come from working in high-pressure environments, including bone-rot and even the bends). There are several reasons for the selection of the tunnel route. Richard Trevithick: An Illustrated Life. There had been an attempt in the late 1700s and, in the early 1800s, a group of Cornish miners targeted Wapping and Rotherhithe as ideal locations for the entrance/exits of an underground tunnel. His inventions, which had brought him to the attention of men as illustrious as Tsar Nicholas I of Russia, included machines for mass-producing cannon balls, embroidering fabric, sawing wood and making ships’ tackle. This structure was placed against the area of earth that needed to be excavated and then workers proceeded to dig in its cavities, removing soil in sections. The hazards of such an operation soon became apparent. This influx was more of a nuisance than a real danger while the pump was working, but in the summer of 1826 it failed, and the whole shaft was soon flooded to a depth of 12 feet.
