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. Thepermeability 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.

A GEWIPile 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.

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 THREADBARin the

concrete-filled center of the pile

Pile Components

Buildings and Factories

With 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 Support

Pipelines can be laid on special pipeline

saddles, which are mounted directly onto

the DYWIDAG Ductile Iron Piles for a

settlement free support.

Infrastructure Projects

DYWIDAG Ductile Iron Piles are used for

the foundations and the strengthening of

new or existing roads, railway lines and

bridges.

Pile Production

Rapid 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.

Physical Properties

Grout Injection Shank with Grout Box

is used for installation of grouted

friction piles. Sanded grout (with a max.

aggregate size of 5/32 in.) is pumped

through the pile as it is driven, ensuring

that the annulus between the pile shaft

and the ground is fully grouted.

Accessories

Dry Driving Shank

This shank is used for end bearing piles

that are driven dry (without grout). One

side of the shank is connected to the

hammer and the other fits into the bell en

of the pipe.

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

DSI has a large inventory of stressing

equipment that enables our customers

to test and lock off bar and strand

tendons of any size. The stressing jacks

are complemented by stressing chairs,

pulling heads and hydraulic pumps for

safe and efficient stressing operations.

Customized equipment has been

provided for many jobs with difficult

access or for high capacity anchors. Our

in house engineering staff is well suited

to work with you on your job specific

details and requirements.

Hollow Bar Grout Swivels

Grout Swivels are used for a simultaneous

drilling and grouting operation. The Swivel

allows for injection of grout through the

bore of a rotating DYWIDrill Hollow Bar

into the hole. The unit comprises of a heat

treated shaft (to withstand the impact

energy from the hammer drive) and a

housing into which the grout is pumped.

Inlet ports within the shaft allow grout to

be pumped into the bore of the bar.
