This optimal solution provides builders with a state-of-the-art three hinge segmental precast concrete arch system for building short to medium span earth-overfilled bridging structures.<\/p>\n<\/div><\/div><\/div>
Now a matured choice for engineers, TechSpan\u00ae arches are built for:<\/p>\n
The TechSpan\u00ae solution, while sophisticated in terms of design is simple for planners and builders to incorporate into their projects. These structures are designed to accommodate high fills, heavy live loads, as well as alternating loading conditions imposed during both installation and in service conditions.<\/p>\n
Each\u202fTechSpan\u00ae\u202fstructure is specifically designed, structurally and geometrically for your application. Finite element model analysis design (FEM) accurately defines the optimal radius of curvature of the arch to minimize tensile stresses. Our approach results in slender concrete sections with optimized reinforcement for maximum safety in design and construction, with long service life at the lowest possible cost to the builder and end user.<\/p>\n
Using our unique flexible concrete precasting formwork and quality-controlled casting process results in finished elements that conform to any and all geometric and material quality specifications.<\/p>\n
Our design and material supply package often includes materials required to construct the necessary retaining structures for wing walls and spandrels, and also other precast solutions including footings, copings, barriers and slip joints.<\/p>\n
Requiring only a narrow footprint to build, TechSpan\u00ae installation is simple, rapid and predictable requiring only a small work crew, light tools and conventional equipment. Erection rates of 10 to 20 linear meters of arch per shift are easily possible with only a single crane with operator, while the use of two cranes with operator will speed production at the initial start of installation.<\/p>\n
The TechSpan\u00ae solution eliminates the need for intensive onsite formwork, scaffolding, joints or bearings. Installation over active roadways, railways, waterways and conveyance systems is possible without disruption to the ongoing activity.<\/p>\n
The abbreviated installation procedure consists of the following steps:<\/p>\n
The inherent durability of quality precast concrete\u202fprovides a long service life with minimal maintenance requirements.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
As opposed to alternatives, the cost savings using TechSpan\u00ae increase as the fill height imposed on the arches increases.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
A full scope of services, from inception to completion:<\/p>\n
Designs and materials for headwalls, wing walls and collars are conveniently included in the Terre Armee material supply package.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
