foundation construction and repair
Hubbell Power Systems (HPS) manufacturers a wide variety of transmission, distribution, substation, OEM and telecommunications products used by utilities. In addition, HPS products are used in the civil construction, transportation, gas and water industries. Products include construction and switching products, tools, insulators, arresters, pole line hardware, cable accessories, test equipment, transformer bushings and polymer precast enclosures and equipment pads.
The AT Foundation concept is simple. The wires run through a clamping mechanism which prevents the wire from being pulled out of the ground through the baseplate.
The beauty of the device, for lighting contractors, is the fact that there's one less piece of hardware to order and one less piece to deal with logistically - the device is built right into the foundation. There are no separate parts to align when seting the pole and aligning the anchor bolts.
A typical Instant Foundation anchor can be installed in minutes using standard equipment. The superstructure can be mounted immediately - no waiting for concrete to cure. CHANCE foundation anchors can be installed in all weather conditions, thus eliminating weather related delays. They can function as permanent installations or serve as temporary foundations. They can be easily retrieved and reused.
The CHANCE Instant Foundation System includes a broad range of foundation anchors with various attachments for field adjustments. CHANCE support services include analysis of soil boring data, job-specific foundation anchor recommendations, personnel training videos and hands-on demonstrations.
Economical, No Site Preparation, Versatile
Be more profitable and meet your customers' concerns. Immediacy of low-cost installation delivers a total product with performance that builds your reputation.
Specifically designed for above-grade and on-grade mounting of parking-area/site lighting standards, these non-extendable foundation anchors have high-strength pipe shafts to resist bending moments and substantial installing-torque ratings. They often can be installed through macadam surfaces.
The FAA often uses this system on PAPI and NAVAID systems to place foundation systems deep in the soil below frost heave and expansive soil movements. The same is true for railroad signal boxes and emergency call boxes along highway systems. Simply positioning the foundation anchor and rotating it into the ground gives the structure a stable high performance foundation.
Economical, readily available, predictable and measurable capacity during installation are some of the advantages of the CHANCE INSTANT FOUNDATION® System. We have available information on applications, on wind generators, satellite receivers, solar panels, and other devices requiring stable foundations.
Plain extensions are then added in standard lengths of 3, 5, 7 and 10 feet until the lead section penetrates into the bearing strata.
Typically, square shaft extensions can be used in both compression and tension applications. Round shafts are more commonly used for compression and have a greater section modulus, resisting bending in weaker soils.
Shaft (RS) extensions. The type RS-SS combination transition is used mainly in compression applications in areas where soft/loose soils are located above hard/ dense soils. The type RS material is less susceptible to buckling, provides greater lateral capacity, and greater moment capacity, than type SS material.
A square shaft lead will allow better penetration of the helices into hard/dense material than round shaft (RS). SS reduces the occurrence of "spin-out" (loss of thrust of helices).
To begin the process, a helical anchor/pile is placed into the soil by applying torque to the shaft. The helical shape of the bearing plates creates a significant force that keeps the foundation advancing into the soil. After the Lead Section with the helical plates penetrates the soil, a Lead Displacement Plate and Extension are placed onto the shaft. Resuming torque on the assembly advances the helical plates and pulls the displacement plate downward, forcing soil outward to create a cylindrical void around the shaft. From a reservoir at the surface, a flowable grout immediately fills this void surrounding the shaft. Additional extensions and displacement plates are added until the helical bearing plates reach the minimum depth required or competent load-bearing soil. This displacement pile system does not require removing spoils from the site
Where site conditions and load requirements warrant, this system combines CHANCE® helical tieback anchors with Atlas Resistance® Piers. The helical anchors contribute lateral support to the piers providing vertical support. This unique combination forms a fast, effective solution for challenges beyond the capabilities of other systems
This adapter is used to connect two tools having incompatible bolt circles: One with a 5 1/4" bolt circle and one with a 7 5/8″ bolt circle.
