Vertical Shaft Construction to 80 Feet Deep

Capitol Tunneling Inc. has extensive shaft sinking experience ranging from 5-foot diameter to 30-foot diameter. Our shaft crews have installed nearly 6000 vertical feet of circular shaft ranging from 5 feet to 30 feet in diameter. We carry an inventory of linear plate shoring and ring beams to readily construct vertical shafts that range from 10 feet to 17 feet in diameter and from 10 feet to 80 feet deep. Do you have a point repair to make in a tight heavily congested area, or a deep manhole to install, or even specific excavations that cannot be constructed with traditional trench shoring techniques? Our shaft sinking expertise is ready and waiting for your call.

Capitol Tunneling, as part of one of our Design/Build contracts, designed and installed 70 vertical feet of 16-foot diameter shaft over a miter section of the failed pipe. The shaft was primarily used for access into the failing pipe. The last 15 feet of the shaft had to be retrofitted to an 18-foot diameter off-set shaft to facilitate encapsulating the entire host pipe. Capitol Tunneling crews and designers fabricated and installed this one of a kind off-set with ease and professionalism. The shaft was structurally sound and maintained its structure integrity for the duration of the project. Again, our crew’s expertise and our firm’s dedication to the completion of a successful project stand out in everything we do.
