Pipe Jacking

Pipe Jacking

Pipe jacking is a trenchless tunneling technique used to install underground pipelines with minimal surface disruption, using powerful hydraulic jacks to push pipes through the soil while hidden behind a protective shield.

In this paper, the soil disturbance mechanism associated with adjacent pipe jacking excavation is studied. A cylindrical hole expansion model is developed and an analytical formula for deducing plastic zone disturbance radius calculation of soil is devised.

Early Life and Education

At first, he studied piano for three years but did not become proficient. Additionally, he learned Highland dancing alongside his brother before eventually beginning to compete as a piper at numerous international competitions and winning several medals himself.

JHW Pipes was such a success that Weinberger needed additional assistance. To fulfill this need, he hired Gary Friedman from High school as additional help – not because of any particular skill but simply due to being lazy! Gary eventually produced some astonishing freehands that became invaluable resources within a relatively short amount of time.

Together with Maxine (who manages family businesses), they have donated to TU for many years; their contributions supporting student scholarships and programs, local organizations, businesses and being members of the Foundation Board.

Professional Career

Pipe jacking is a trenchless tunnelling method which enables underground pipes to be laid without the need to dig a trench, making it particularly effective at installing in protected natural areas and densely populated urban environments where excavation processes could cause disruption or cause significant roadside construction delays. Furthermore, its application near historic buildings may result in less damage compared with conventional excavation techniques.

Selecting an appropriate pipe jack for your roof is crucial, ensuring it complements your roofing system and that its installation goes as smoothly as possible. Boot and flashing must be watertight for proper functioning while resistant to squirrel chewing can prevent leaks in your shingle roof from developing around it.

Personal Life

Judy Kishner (BA ’74, JD ’77) and Gail Richards, Jack and Henry’s daughters, continue their family’s tradition of giving back to Tulsa through their foundation. Their gifts to TU have supported many projects and programs such as athletics, Gilcrease Museum, McFarlin Library, student scholarships and student support services.

As Pipe Sergeant for Simon Fraser University’s bagpipe band, Jack travels each year to Scotland for solo piping competitions, winning several major titles such as Bratach Gorm London 1994 with “Lament for Earl of Antrim”.

His devotion to music can be seen through the time and care that goes into crafting unique Uilleann pipes from leather, exotic Australian woods, and nickel silver – offering these custom pieces for players around the world to use – the process can often take years!

Pipe jacking is similar to CIPP but uses hydraulic jacks rather than percussion for tight directional control and cost effectiveness. Pipe jacking allows longer lengths of pipe to be installed at once than pipe ramming does, as it uses hydraulic jacks rather than percussion.

Henry and Jack Zarrow founded Sooner Pipeline as a major distributor, catering to many prominent clients, while simultaneously expanding TK valve and manufacturing into Canada, Scotland, and Singapore.

In 1996, Insituform acquired Kinsel Pipeline and later Elmor Pipe Jacking; with this expansion came new leadership led by Anthony W. Hooper who served as president of Insituform of North America for more than two decades before taking his current post as chairman of Insituform Technologies, Inc.
