CHAMPION SPLICER HP –
Champion Splicers – approved and used to extend H-piles in
City as early as 1955. They have been
utilized across the country and around the world for the past forty years, with
no failures. Tests at New
State "Campus" Site on HP 14x73 driven
to 200-ft. depth with three Champion Splicers and
loaded to 400 tons led to approval of the Splicer for
3,000 piles in 1962.
There have been many unusual and repeated projects;
a few have been recorded in PILETIPS. Here are some condensations:
THREE RETURNS TO POWER PLANT
For a power
plant along the Ohio River, Stanley Consultants, with Dames
& Moore, specified Pruyn Points and approved
Champion Splicers, HP-30000 for 14in. H-piles to be
driven into heavy clay and boulders. In 1972, Richard Goettle used a 60,000 ft-lb hammer to drive, then a Foster
275E vibratory to pull test piles. Despite hard driving to over 115-ft. depth –
and harder pulling -- the piles, points and splicers
were intact. This was observed very closely as the piles were partially
installed with the vibratory.
In 1974, Goettle
was back to drive 600 HP 14 and HP 10 with specified APF points and splicers. In 1976, E.E. Gillen Co. drove 1200 piles with
specified Pruyn Points and Champion Splicers. In 1977, Goettle
returned to drive 350 piles, many of which had two Champion Splicers. Repeat use of APF points and splicers over several years proves their value for design
and their economy for contractors.
GE TURBINE TEST
Support for a General Electric turbine test facility where NO
settlement could be tolerated is on 400 HP 14x73 driven by Carter Pile Driving,
Inc. A 60-ft length was driven to convenient working height above the ground.
The HP-30000 splicer was slipped on the driven length.
A 30-ft. section was set into the splicer and corners
welded. The crane moved on to the next pile while single-pass groove welds were
made along flanges.
FOUR PIERS AT GROTON SUB BASE
Splicers, HP-30000, have been approved for four
successive pier installations at the U.S. Submarine base at Groton-New London,
CT. Navy personnel designed one of the piers. Different consultants prepared
plans for others. All projects used APF's cast steel
points to secure a toe-hold on sloping rock with piles battered as steeply as
Water is deep, piles are long, one or two Champion Splicers, HP-30000, were used for each pile with APF Pruyn Point protection. Splicers
were especially advantageous as driving was done from floating rigs where there
is continuous movement. With the Champion fixed on one length, the added section
could be quickly positioned and held securely while welds were made along each
flange and at each corner of the splicer.
INDICATOR PROVES STRAIGHT
HP 14x73 driven to 200 ft depth at a 1:3 batter stayed within two
percent of plan location despite use of three lengths and two Champion Splicers. The project is a power plant along the
designed and built by Burns & Roe as a turnkey project for a power

pre-attached almost continuous driving could be achieved. In this and others,
soils friction sets-up quickly requiring extra blows and time to get the pile
To verify that the piles were in proper location to carry 100
tons design loads checking with a Digitilt Slope
Indicator was required on several piles. Deviation from specific batter averaged
under 2% on either axis.
The HP 14x73 were protected by Pruyn Points for
driving into boulders and hard clays to irregular rock at 150 to 200 ft depth.
Driving was done with a Vulcan 0-10(32,000ft-lb) hammer.
Engineers who had no previous
experience with Champion Splicers were reluctant to
accept the HP-30000 unit as equivalent to the specified full penetration butt
weld. Structures were high and hurricanes occur at the northeast
The APF Champion
H-pile Splicer has been proven by use, tests and
observation over many years in practically every state and in all types of
soils. Many piles with APF Splicers have been driven,
test loaded and pulled. Observations have been analyzed by job forces and
reported by APF engineers. There are no known failures of APF Champion Splicers.
Tests made at the highly qualified Fritz
Engineering Laboratory at Lehigh University proved the Champion Splicer to be a strong, effective splice. Tests were made on
HP 14x89 and HP 10x42 on both XX and YY axis to provide complete proof of the
integrity of the splicer. These tests cover the full
range of H-piles; loading on the YY weak axis is of top importance as the loads
may come on the pile in any direction.
Piles were prepared for testing by
regular workmen following APF details for making the splice. Under loading to
destruction, failure in each case occurred by crippling of the pile outside of
the splice area. This is to be expected as the tight fitting, strong Champion
Splicer supports the flanges against bending and
The sketches and chats show the
results of loading to failure. The loads applied on the weak and strong axis
corresponding closely to the full moment capacity of identical unspliced beams. The test pieces, with the Champion steel
H-pile splicer, had sufficient strength and ductility
to develop the full capacity of the member when loaded on either the YY or XX
axis. The elongation across the tension side of the splice translates into
tension value of the connection. Since this is only one side, the uplift
resistance across the joint is actually double the value shown.

cases, failure was simply loss of capacity under increasing deformations-not a
catastrophic collapse. More than adequate capacity to resist rotation was
provided by the Champion H-pile Splicer as evidenced
by the large deflections sustained before failure-which occurred outside the
The Champion Splicer is fabricated
with close control of the space for insertion of each weight of the H by a
heavily welded bar. With tight fit against the flanges and accurately formed
corners for easy entry, the HP-30000 is best for load carrying ability and speed
of construction. The strength and integrity of a splice is jeopardized if there
is a loose fit. A loose fit is dangerous to workmen, especially where they have
come to rely on the security of the APF Champion Splicer.
Owners and their engineers can benefit form
the exceptional strength capability of the Champion Splicer. Contractors gain from its uniformity, dependability
and prompt availability to speed construction.
APF Champion Splicer is the safest and fastest means to extend H-piles.
It is approved by public agencies and is accepted by federal authorities. The
Champion Splicer is the time-saving favorite of
knowledgeable engineers and foundation contractors. Specify and use the APF
Champion Splicer, HP-30000, for the best solution to
- Accurately fabricated for each
size and weight of H-pile.
- Quickly available for delivery to
your job when needed.
- Time saving: Simple attachment for
dependable strength, equivalent to an unspliced
- Economical: Save crew time and
equipment expense on every job.
The Federal Highway
Administration, other U.S. government agencies, state
transportation departments and almost all jurisdictions accept and approve the
APF Champion Splicer for H-piles when attached as
recommended by Associated Pile & Fitting Corp. This is simple, rapid and
A simple bevel is burned along the outside of each flange of
the section of H to be added. A 2x2in. angle can be used as a guide for the torch. A notch for the
heavily welded spacer is cut in the web of the H. This can be in either length
of H as the spacer is offset to require only one cut.
The Champion Splicer is slipped on the H and a 2-1/2 in. length of
5/16-in. weld made near each corner of the splicer.
Doing this in advance saves time for the crew as it quickly aligns and holds the
added length. Safety is greatly improved as the top section is held securely
against wind gusts or crane movement. Use of the APF Champion Splicer speeds the connection and release of the handling
equipment. Positioning lugs are not needed. Exact alignment of the pile is
KEEP PILE STRAIGHT
Keep the added length of H in
axial alignment. If the lower section drives a little out of position accept
that and add in a straight line. The Illinois Department of Transportation
estimates a batter pile to have 98.8% bearing
value, is 97%; is 94.6% and even a sharp
is 91.7%. (PILETIPS July - August
1980) This is well within usual safety factors and will be far better than
welding in a dog-leg at the splice.
The simplest solution for correct
location is to always start the pile in accurate position and careful alignment.
Check with a long carpenter's level and re-check as driving starts. For batter
piles, plywood cut to the slope is attached to the level.
Prior to introduction of the Champion Splicer, the slower and more costly butt weld was the
accepted method of extending H-piles. This alternative to the quickly installed
and safer Champion Splicer requires a full penetration
butt weld across both flanges and the web. To attain full penetration welds,
plates should be used to back up the weld or the weld should be back gouged to
good metal and filled in. For welding, flanges should be accurately aligned with
plates and wedges. (Bethlehem Steel /corp. H-pile

JOB SAFETY, SPEED, ECONOMY
Associated Pile & Fitting
Corp. developed, tested and proved the one H-pile splicer that is safest to install, economical and most
dependable of all means of extending driven H-piles. The Champion Splicer, HP-30000, is precision formed and accurately sized
for each size and weight of H-pile. It is available for stock for immediate
The Champion is imitated but never duplicated. Bends and even
beveling do little to ease or speed installation. Only the Champion has been
proven by professional laboratory testing plus forty years of
CHAMPION H-PILE SPLICER
The Champion Splicer speeds production. It is placed in advance on one
length of pile. The outside bottom edge of each flange of the top section is
scarfed to accommodate a bevel weld. The new piece is
quickly positioned over the driven pile and slipped into the accurately flared
Champion. The heavily welded spacer holds the splicer
components strongly; it accurately aligns the web and flanges of the added
length. This firm connection eliminates the need for alignment lugs and wedges
that must otherwise be welded on the pile and later removed.
Splicer adds to job safety. It is already in place on
one length of pile and slides quickly on the other section. This prevents wind
gusts or sudden crane movement swinging the pile dangerously as workmen move in
to make simple welds along each flange and short fillet welds near the corners
of the splicer. The Champion Splicer is especially helpful when driving from floating
equipment where there is always movement. Connection is speeded and the piles
kept in accurate alignment for welding, with safety.
