DSI Liner PlatesDSI Liner Plates

Without adequate protection, tunnel construction, slough-ins and other concentrated loads are volatile, and results can be disastrous. DSI’s Liner Plates provide optimum stability and protection for tunnel construction. Steel liner plates provide a relatively light-weight, easy-to-handle, safe support for soft ground tunneling. With decades of experience in the tunneling industry, DSI has mastered the plate design with variations to fit all shapes of tunnels in dry or wet ground. DSI Liner Plates also offer advantages such as economy of construction in time, excavation, material and manpower. They are manufactured to provide maximum support per given length with minimum weight of steel. During the critical mining phase in soft ground tunneling, DSI Liner Plates deliver continuous support and predictable strength. All of DSI’s ground support systems are designed to make tunneling safer. Thanks to its local presence around the globe, DSI can satisfy your needs for ground control quickly and efficiently.

EPC BarChipEPC – BarChip

EPC have never accepted corrosion. Structural steel reinforcement has been used in concrete for over 100 years, and for over 100 years corrosion of steel reinforcement has been an issue. EPC designs around it with increased cover, special mixes and other complicated preventative measures. No matter what, corrosion still sets in. There must be a better way. EPC USA Director Pat Lewandowski states: “Eliminating corrosion has always been a fundamental driver in the growth of BarChip fiber use. Most designers ask, ‘How can we design our structure to minimize the effects of corrosion?’ At EPC we ask, ‘How can we eliminate corrosion entirely from our structure?’ ” BarChip structural synthetic fiber concrete reinforcement is the leading fiber in the global market and eliminates the risk of corrosion. BarChip has reinforced over 100 road, rail and utility tunnels and is the only fiber to completely replace steel reinforcement in precast segmental tunnel linings.

HNTBHNTB

Today’s complex underground structures and tunnels must account for probable incidents affecting tunnel services and liners, especially tunnel fires. Proper tunnel design considers the effects of design fire events and related temperature impacts on tunnel liners and other essential permanent structures. These structures must be designed to protect users and operators during a fire event. Design also should allow for repairs to be implemented in a timely manner so the facility can return to normal operation as soon as possible and economic impacts are minimized. In addition, design must be efficient and economical. HNTB’s award-winning tunnel expertise includes full service fire/life safety solutions, including ventilation analysis with active and passive fire protection systems, roadway lighting modeling, systems power, fire alarm and controls.
