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. Available splicing methods utilize steel type connections that are more suitable for reinforced concrete construction and result in limited tensile capacity at the …
MAY 1984 SPECIFICATION 1016 M SPECIFICATIONS FOR DRIVING PRECAST CONCRETE PILES 1016. 1. DESCRIPTION The work will consist of handling, locating, aligning and driving precast concrete piling and cutting off piles at the required elevations. It will also include building up piles to the required
Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces transportation costs because concrete can often be recycled in areas near the demolition or construction site.
Precast Concrete Piles DC Piling manufacture continuously reinforced precast concrete piles, cast in standard square sections from 220mm to 360mm. The pile lengths range from 4m to 13m, increasing in 1m increments. Longer piles can be achieved by means of jointing. This allows piles lengths to be extended on site very quickly using a mechanical …
AARSLEFF Sp. z o.o. specializes in the design and execution of deep foundation work using the technology of precast reinforced concrete piles.Due to the possibility of carrying vertical and horizontal loads as well as bending moments, precast piles are used for the foundation of all sorts of engineering structures under virtually every soil conditions.
Jul 27, 2015 · 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 ...

Aug 04, 2017 · The process of quality control for this group of elements is very much through indirect measurement of other parameters, i.e. resistance of pile to driving or drilling, or other non-destructive testing techniques (NDT). NDT methods can shed light on this hidden part of concrete piles. Integrity Problems of Concrete Piles
Eriksson Software is an engineering software development firm located in Tampa, Florida. We specialize in analysis and design software for precast/prestressed concrete in both the transportation and commercial markets.
Jul 02, 2015 · Reinforced concrete is an important technological milestone in construction as it endowed a structure with features that gave it a long life and also protected people living in the structures from external conditions. Today, reinforced concrete is a popular and widely used form of concrete. Reinforced concrete comprise of two things – one is ...

The paper introduces the work process and control requirements of precast concrete pipe pile perfusion. Th design is based on the S7-200PLC and AE80THTD touch screen control system. It elaborates the hardware components of control system, I / O configuration, software workflow and control chart.
Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.
