For pipes used for pipe jacking, they should possess the following characteristics: (i) Pipes should have high concrete strength to withstand the stress induced during the jacking process. (ii) There is tight tolerance in pipe dimension and the pipe joints are specially designed to provide trouble-free joint details. Standard Jacking Pipes. Tracey Concrete manufacture a wide range of Jacking Pipe sizes which incorporate the tried and tested butt end joint system with cast in steel band. Tracey Concrete Jacking Pipes are manufactured in accordance with BS EN and BS, BSI Kitemark certification.
Pipe Jacking: A system of directly installing pipes behind a shield machine by hydraulic jacking from a drive shaft such that the pipes form a continuous string in the ground.

Pipes are vertically cast to produce accurate joint surfaces with square faces and a strong high density concrete. Interjack stations with integral ‘cans’ and ‘lead’ pipes are available. Grout injection points and a lifing hole can be cast into pipes on request. Jacking pipes are manufactured to . Abstract. The term pipe jacking is used to describe an installation method as well as a concept that is fundamental to a number of trenchless techniques. It is important to differentiate between the principle and technique. Pipe jacking can be described as the principle of using hydraulic rams to push preformed sections to line the hole formed by a cutting head or by:

The jacks are positioned in place on supports. A section of concrete pipe is lowered into the pit. Pipe The jacks are operated, pushing the pipe section forward.
Pipe The jack rams are retracted and a “spacer” is added between the jacks and pipe. Pipe Spacer The jacks are operated and the pipe is pushed forward again. Jacking concrete pipes book PipeFile Size: 2MB. Ward says that many concrete pipe manufacturers are more than capable of delivering high-quality jacking pipe.
The crucial aspect is creating a high-quality mold. The tolerance of jacking pipe needs to be higher than typical open-cut concrete – on the order of 1/16th of an inch. Steel reinforced concrete jacking pipes are capable of withstanding higher jacking loads.
The jacking load capacity of standard pipes for a range of joint deflections is illustrated in Figures 4 and 5 on the following page. Pipes with higher jacking loads and/or joint. Reinforced concrete jacking pipes are one of the most commonly used materials used for jacked pipe installations.
The existing Australian / New Zealand Standard (AS/NZS ) for concrete pipes has little or no relevance to jacking pipes. This has forced. Jacking Concrete Pipes are a specialised tunnelling pipe, the jacking pipe is lowered into a shaft behind a TBM (tunnel boring machine)then pushed underground by hydraulic jacks creating a pipeline without the need to dig a trench.
Jacking pipe have to withstand huge pushing forces from the hydraulic jacks. Pipe jacking, generally referred to in the smaller diameters as microtunneling, is a technique for installing underground pipelines, ducts and culverts.
Powerful hydraulic jacks are used to push specially designed pipes through the ground behind a shield at the same time as excava-tion is File Size: 1MB. materials to include concrete, clay, grp and steel can be jacked and standard pipe diameters generally range from mm to 2,mm, 4 An introduction to pipe jacking and microtunnelling.
1 THE PIPE JACKING TECHNIQUE. Typical pipe jacking arrangement Environmental benefits - carbon emissions reduced by up to 75%. Detailed example problems of specific applications illustrate the use of the time saving design aids included in the manual.
The Design Manual is a companion volume to the CONCRETE PIPE HANDBOOK. The Concrete Pipe Design Manual includes a hardbound book with accompanying CD ROM.

In time, however, concrete slabs can crack or sink due to pressure or from movement during settling. Lifting a sunken slab may be necessary to level the surface. Hiring a professional service to lift, or jack up.
G-Cast Precast Concrete Jacking Pipes G-Cast produces a comprehensive range of precast reinforced concrete jacking pipes to suit the modern generation of jacking techniques and systems. Standard pipes are manufactured with flexible joint incorporating well proven butt end joint with cast-in.
Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction covers piping intended for the conveyance of sewage, industrial wastes, stormwater, and drainage, as well as for utilities and access ways.
It presents design and analysis methods that consider the interaction between the pipe and surrounding soil and/or grout envelope in order to determine the longitudinal loads that develop during jacking.

CONCRETE PIPES Standards Currently there are two South African national standards applicable to concrete pipe: SANS - Reinforced concrete pressure pipes SANS - Concrete non-pressure pipes The code of practice for the selection of pipe strength is: SANS - Part 1: Selection of pipes for buried pipelines: General provisions.
Pipes are vertically cast to produce accurate joint surfaces with square faces and a strong high density concrete. Interjack stations with integral ‘cans’ and ‘lead’ pipes are available. Grout injection points and a lifing hole can be cast into pipes on request.
Jacking pipes are manufactured to Max Diameter (?): mm. This Standard, a revision of ASCEaddresses the direct design of precast concrete pipe that will be installed using jacking, a type of trenchless construction.
To successfully install pipes using jacking techniques, engineers must design for loading conditions both during and after installation, and contractors need to ensure skillful.FP McCann provides an extensive range of concrete pipes and fittings.
All products are manufactured from high quality raw materials and are sulphate resistant. FP McCann’s jacking pipes enable pipe installation where the opening of trenches is neither practical nor cost effective. FP McCann’s jacking pipes are made from dense, durable.
