DYnA force™ Sensors for Load Monitoring

Introduction

on many occasions during the construction and service life of a structure is it beneficial to know the force in the tension element of the post-tensioning system. Although there are many methods to measure the tendon force, most of them are cumbersome, expensive, and the accuracy differs depending on the method used. dywidAg has been involved in the development, testing and execution of dynA Force™ to measure the force in the tendon. dynA Force™ is utilized for ground anchors, soil nails, in cable stay bridges and structures to measure the forces during construction and to monitor forces during the service life of the structure. valuable information about load distribution can be obtained if sensors are placed along the bond length of ground anchors or soil nails. dynA Force™ can be used for bare, epoxy-coated and greased-sheathed steel.

dynA Force™ is manufactured based on the theory that the permeability of steel to a magnetic field changes with the stress level in the steel. by measuring the change in a magnetic field, the magnitude of the stress in the steel element can be obtained. the dynA Force™ system does not alter the characteristics of the tendon other than its magnetization. the permeability is a function of temperature and magnetization. A calibration process eliminates the impact of these variables. the system considers the effect of the temperature change automatically. A portable power stress unit is attached to wire leads from the dynA Force™ sensor. this unit will create the magnetic field, measure the residual value and then convert it to a direct force reading.

the accuracy of the force measurement is within 1%. the dynA Force™ system is robust, requires no maintenance and has no moving parts. it is composed of cylindrical, non-contact sensors and a power stress unit (read-out box). dynA Force™ sensors are installed over the strand or bar during construction and a zero reading is taken before applying any post-tensioning force. it is expected to have a similar service life as structure. this will allow the owner to regularly monitor the forces in the post-tensioning system in minutes as a part of their inspection procedures without the need for lift-off equipment or other special expensive techniques. monitoring with dynA Force™ also avoids the inaccuracies and risks often associated with lift-off readings. performing the monitoring requires only one person.

DYWIDAG Micropiles – GEWI® Pile

A GEWI® pile is a drilled and grouted micropile, with a diameter of less than 12 inches. it is centrally reinforced with either one or a group of dywidAg threAdbArs. the deformations on the bar transfer the load into the surrounding grout body and friction transfers the load from the grout into the ground.

Drilling: � compact lightweight drilling equipment allows for pile installation even in areas with low headroom

� small economic drill hole diameters

� drill holes can be placed closely to existing walls or structures

� vibration free drilling prevents damage to adjacent structures

Continuous coarse thread on bars: � provides excellent load transfer into grout

� remains threadable even when dirty or damaged

� allows for splicing and extending the bar at any point

double Corrosion protected (dCp) bars may be utilized for piles in aggressive ground.

multiple bars can be installed into a single borehole.

short bar sections with couplers can be utilized in low headroom locations.

DYWIDAG Ductile Iron Pile

Introduction

the dywidAg ductile iron pile is a driven pile system that utilizes high strength ductile cast iron pipes. the piles are installed in quick succession utilizing an excavator that is equipped with a hydraulic hammer and a driving shank. individual pile sections are connected with a unique spigot and socket joint. the penetration rate during pile driving determines the required pile length.

Advantages

� light and versatile equipment reduces mobilization costs and allows for pile installation in limited space as well as difficult terrain and limited headroom

� quick assembly of pile head

� spigot and socket joint allows for easy, quick connection of pile sections

� very fast and almost vibration free installation with production rates of up to 1,300 lf/day/machine

� pile lengths can easily be adapted for varying ground conditions

� no waste of piling materials

� tension and compression capacities can be increased by placing a dywidAg threAdbAr® in the concrete-filled center of the pile

Pile Components

Buildings and factorieswith working loads between 112 kips and 290 kips, dywidAg ductile iron piles offer comparable loads to conventional mini piles.

Towers power transmission and other towers can be built on small foundations, which transfer the vertical loads into the ground via the dywidAg ductile iron piles.

Applications

Pipeline Supportpipelines can be laid on special pipeline saddles, which are mounted directly onto the dywidAg ductile iron piles for a settlement free support.

Infrastructure ProjectsdywidAg ductile iron piles are used for the foundations and the strengthening of new or existing roads, railway lines and bridges.

8

Pile Productionrapid percussion hydraulic hammers are used to advance the pile into the ground. the first pile section is fitted with an end plug, grout shoe or rock point (pile tip) and driven into the soil. subsequent pile sections are driven into the tapered socket of the preceding pile section.the process is repeated until the required pile depth is reached. if the pile has been installed “dry” (without pumping concrete through the center), the interior void is filled with concrete.

WARnInG!ductile Cast iron piles are not recommended when boulders and/or other obstructions are present.

DYWIDAG Tie Rods


tie rods produced from dywidAg threAdbAr® are used for a variety of applications. Constructions of marine bulkheads for various docking facilities have, for many years, benefited from the use of dywidAg tie rods. Facilities such as barge and ship docks as well as offshore platforms have found the system to be a cost effective alternative to large diameter A36 tie rods with upset threads.

Additional applications for dywidAg tie rods are:

� stabilization of slopes

� horizontal load resistance for foundations and roof structures

� bracing for grade separations

tie rods produced from dywidAg threAdbAr® offer various economical and technical advantages:

� coarse thread allows for rough site handling as dirty or damaged threads will remain threadable

� continuous thread allows for easy on-site length adjustments since cutting or coupling of the rod is possible along its entire length

short bolts are needed to connect a standard sheet pile wall or a modular sheet pile wall to a load distributing double channel beam. this can be done with dywidAg threAdbAr®.

the required length of the bar depends on the depth of the sheet pile profile, the width of the beam, the plate thickness and the nut length.

� stock length up to 60 ft

� bars conform to Astm A615 or Astm A722

� Astm A615 bars are about 50% less weight than A36 bars

� Astm A722 bars are about 70% less weight than A36 bars

� available with many options for corrosion protection

DYWIDAG Temporary Strand Anchors

DYWIDAG Permanent Strand Anchors with DCP (Double Corrosion Protection)

� strand anchors allow for a large range of anchor capacities, as there is no theoretical limit on how many strands can be used in an anchor

� long anchor lengths are possible without the requirement of a splice

� most strand anchors are coiled for transport and require little storage space on site

� utilization of high strength 270ksi strand results in low anchor weight

� the hot melt extrusion process provides a high quality, uninterrupted plastic bond breaker and additional corrosion protection

� specialized installation and stressing equipment is available from dsi
