Bore dug in wet soil flows tricky path
Methods used in building tunnel of storm sewer at Houston, Tex are outlined; shallow 447-ft-long section by open-cut method at one end of job was first installed and then 6500 ft was excavated with wheel-type mining machine; tunnel passes 35 to 40 ft under many streets, railroad tracks, and about 100 utility lines; mining wheel had to go through 15-ft-wide gaps to be bordered by freeway columns later; to control wet ground, workers relied on deep wells, air pressure, and chemical grout.
