CPG Pile Splices

Centrum Pæle A/S in Vejle, Denmark

manufactures precast reinforced concrete

piles. The company dates back to 1882. In

1965, the present company was founded as an

independent public limited company with the

primary purpose of manufacturing concrete

piles. Today the group consists of 5 factories

around Europe with a total production capacity

of more than 3.5 million linear meters of precast

concrete piles.

As a part of our consistent efforts to optimise

the product and its competitiveness, we

have developed and patented our own pile

splice. The CPG Pile Splice was developed

with a focus on making a safe and reliable

connection between two piles, but just as

important – to make a pile splice that is quick

and easy to work with on a construction site

and would help in reducing the total time

spent on installing each pile.

The CPG Pile Splices are manufactured in a fully

automated production process with 6 robots,

to ensure high productivity and standardised

quality. The individual serial numbers and

barcodes furthermore ensure full traceability

on all parts included in each splice.

The properties of the CPG Pile Splices are

tested and documented according to the pile

standard EN 12794 as a class A pile splice,

which means it can be used for hard pile

driving without losing its properties. The CPG

Pile Splice is tested, and CE type approved, and

the production is controlled of the recognised

German “Materialprüfanstalt für das Bauwesen

– TU Braunschweig”.

Capacities Compression & tensile capacityCentrum Pæle pile splices have been tested according to standard EN 12794:2005 +A1:2007/AC:2008 and categorised as Class A.

The static load bearing capacities of the pile splices are shown in Table 1. The capacities have been calculated according to Eurocodes with the recommended values of correlation and partial factors and may thus have to be adjusted according to the respective national annexes.

Table 1: Product range with maximum load bearing capacity for pile splices. Annex B9 and B11 applies to pile splices with increased concrete cover.

* The tension capacity has to be reduced with a factor 0.88 for the CPG-K6 and CPG-K8 pile splice in combination with C40/50 concrete. For full tension capacity for the CPG-K6 and CPG-K8 pile splice the length of the reinforcement has to be 900mm.

Basis of DesignThe calculation of the pile splices complies with the following building regulations and assumptions:

EN 1992-1-1 Eurocode 2: Design of concrete structures; Part 1-1: General rules and rules for buildingsEN 1993-1-1 Eurocode 3: Design of steel structures, Part 1-1: General rules and rules for buildingsEN 1993-1-8 Eurocode 3: Design of steel structures; Part 1-8: Design of splicesEN 206-1 Concrete - Part 1: Specification, performance, production and conformityEN 12794 Precast concrete products - Foundation piles EN 10080 Steel for the reinforcement of concrete - Weldable reinforcing steel - General

Concrete design compressive and tensile strength is determined according to EN 1992-1-1, section 3.1.6 using:

Lap length between splice reinforcement and main reinforcement of the pile has been calculated according to EN 1992-1-1, section 8.4 provided good bond conditions, straight anchorage type and reinforcement bar in tension. In order to meet these assumptions, the following coefficients have been used:

The required length of reinforcement needed to obtain the maximum tension capacity of the pile splice given in Table 1 is l0 = 800mm.
