particularly, the present invention relates to spliced precast, prestressed concrete piles. BACKGROUND [] Precast, prestressed concrete pilings (PPCP) are commonly used for deep foundations required under bridges, buildings, and marine structures. Every year millions offeet of precast pile are produced in the United States and driven as.   Precast and prestressed concrete piles can be manufactured in a number of different ways. They are often cast with a hollow core in order to reduce weight, with the head and the toe of the pile cast solid. The hollow core can be used to place instrumentation doing construction or to determine pile damage. Precast concrete piles usually have a. The idea of prestressed concrete has been around since the latter decades of the 19th century, but its use was limited by the quality of the materials at the time. It took until the s and ‘30s for its materials development to progress to a level where prestressed concrete could be used with confidence.

Pile Inspections • Verify METS-release tags release pile, or cast date marked directly on precast concrete piles by METS. • Check pile lift ring removal and patching requirements per the contract specifications 6. Spun Concrete Piles come with a standard beveled end-plate at both ends, which allow quick splicing. ICP Piles are cut with a skilsaw equipped with a diamond tooth blade. ICP have been producing piling since , and is the largest manufacture in South East Asia with eleven ISO certified plants. Piles tend to be over-driven (driven to higher resistance than necessary if setup was better deï¬ ned) in order to meet the schedule. North Carolina (NCDOT) NCDOT utilizes two main pile types: H-piles and prestressed concrete piles. H-piles are commonly used throughout the state; prestressed concrete piles are used primarily in the coastal plain. the driving of precast and prestressed concrete piles. Mechanisms are now available to make it possible to remotely shift from a short to a long stroke in a matter of seconds. There is, however, the ever-present possibility of oversupplying short-stroked ham­ mers with steam or air, and temporarily reduced energy blows are not to be considered.

  Plain concrete is used when the structural load is only compressive. If moments and lateral loads are to be transferred, then a steel reinforcement cage is used in the upper part of the pile. Precast concrete piles usually have square or circular or octagonal cross sections and are fabricated in a construction yard or a factory from reinforced. Versatile precast, prestressed concrete piles can be specifically designed to meet the needs of each individual project.

Splicing Precast Prestressed Concrete Piles by Roberta L. Lincoln The Boston Edison Company in Everett, Massachusetts, was looking for an economical, easy-to-use yet strong splice for precast prestressed concrete piles. The company decided to use a splicing technique that was originally developed in Sweden.

Abstract: A system and method for splicing precast pre-stressed concrete piles and bringing pre-stress forces to each end of the piles with splice plates and with sockets cast in the splice plates to receive pre stressing strands, strand wedges to engage the strands in the sockets and transfer the pre stress forces to.

influencing the selection of prestressed pile are pile prices and availability. When designing a foundation a review of current unit prices for prestressed piles available in the area should be made before selection is made.

Fig. 3 illustrates typical unit prices for square prestressed concrete piles FOB fabrication yard. Fig. 4 compares. In prestressed concrete piles anchorage of the strands is being developed in these areas, and transverse tensile stresses are present. If no spiral reinforcing is used the pile head may spall or split on impact of the ram.

Fatigue of the concrete can be caused by. Prestressed Piling Prestressed concrete piling are vital elements in the foundations of buildings, bridges and marine structures throughout the world. They vary in size from 10 in.

( mm) square piles used in building foundations to the 66 in. ( mm) diameter cylinder piles. Precast, prestressed concrete pilings are often the preferred choice for permanent, durable, and economical foundations - especially in marine or bridge environments - due to their excellent adaptability and resistance to corrosion.

Piles can be spliced together to create longer piles. Concrete Precast concrete piles shall be constructed in accordance with the details shown on the Drawings, and of the concrete class, proportions, method of mixing and placing in accordance with the provisions of Section All cement used shall be type 1 and concrete shall contain not less than kg of cement per m3.

According to ‘Michael Tomlinson & John Woodward’ (Author of Pile Design and Construction Practice), Precast Concrete Piles have their principle use in a marine structure, i.e. in situations where the use of cast-in-situ concrete piles or prestressed concrete piles is impracticable or uneconomical.

Also, Precast concrete piles are suitable. A broad range of splices for precast-prestressed concrete piles were evaluated, based largely upon information furnished by fabricators, designers, and proponents of the various splices.

Basic considerations included size range, field time for splicing, approximate cost. SLICING OF PRECAST PRESTRESSED CONCRETE PILES: PART TESTS AND ANALYSIS OF CEMENT-DOWEL SPLICE.

This technical report covers all aspects of the uses of precast concrete piles - design, manufacture, transport, handling, pitching and driving.

Both reinforced and prestressed concrete piles are dealt with and attention is paid to the use of both plan piles and those with enlarged toes. Although the report is a translation of parts of a set of Author: Ceb.

Precast prestressed concrete piles are widely used in deep foundation construction. Due to unexpected site soil conditions and difficulties associated with transportation and handling long precast piles, splicing is sometimes necessary at the construction site.

RTAB (Epoxy Splice for Precast Concrete Piles) should be included on the pile drawings. Where piles are required to be spliced, the minimum depth below ground level to the splice (Prestressed Concrete Pile – Hard Driving Conditions) shall be used for pile drawings where hard driving conditions are known to exist.

A pipe pile splice is set on the driven section and the top pile segment is set into the sleeve. Intermittent fillet welds can be used to increase the limited tensile strength of the joint. This splice has been used extensively on Bruns piles in the New Orleans area; these splices both in the mould and in the field are shown below.

The piles are cast in a pre-casting plant and then transported to the site. This creates a pile made of high quality concrete under controlled casting and curing conditions. The process. Prestressed precast concrete piles One of the options for establishing pile foundation is the use of prestressed-precast concrete piles (PPCP) (Figure 7).

This option provides in many cases an economic alternative to other pile foundation types and accelerates the construction process, especially in marine environments.
