Ditch Witch JT3020 All Terrain Improves HDD Productivity
PERRY, Okla. — The Ditch Witch® JT3020 All Terrain features all terrain technology, one of the Ditch Witch organization’s many patented innovations designed to simplify the HDD process. One of the company’s breakthrough innovations was the slant-faced drill bit, which revolutionized the industry by enabling HDD operators to steer the drill head. All Terrain technology improves upon the steering process with a patented dual-drive pipe system, which enables the JT3020 All Terrain to drill and steer at the same time. This is an advantage over single-rod systems, which are not capable of steering as well, if at all, in consolidated soils. The inner pipe of the JT3020 All Terrain’s two-pipe drill string continuously turns the drill bit at 150 to 400 RPM, depending on the soil, resulting in exceptionally efficient boring.

Liquid Soil - A Technical Challenge
In the last decades there have been many innovations in the field of plastic pipe systems, especially the bauku GmbH had a strong share with developments like the PROFILEEN - safe or the PROFILEEN - drain clean. However in the field of installation methods and installation materials for sewer pipes there has been no real movement until lately the expression "liquid soil" played an important role in more and more symposiums and expert articles. If someone has a closer look at the definition of this word, it is quite clear that this is not a standardized expression for a certain kind of product and that the products of different suppliers have also a much different product behavior. The bauku GmbH faced this challenge and made a first experience in the static design for this application and the practical use at the job site. As such a pioneer work requires a close connection between the pipe producer and the supplier of the liquid soil, the company rss was chosen for the project.

Repairing sewers without excavation
When repairing sewers, the UK based company OnSite’s nodig solutions can often use manholes rather than digging up roads: Until about thirty years ago, once a sewer was built, there was no way of inspecting the inside. But with the emergence of closed-circuit television, the poor condition of many sewers was revealed. Pipes were often cracked and groundwater infiltration was increasing the volume of sewage at the pumping stations. This led to an overload of the system, with sewage overflowing into watercourses. Treatment plants were working unnecessarily to process the additional volume and sometimes sewage seeped directly into the environment through the cracks.

Grundoram to the rescue: Grundoram Taurus rescues long undersea HDD recovery operation on the Berri Causeway project in Saudi Arabia
In 2007/8 a pioneering HDD project was started using Trenchless Technology on the Berri Causeway and Abu Ali Island on the Persian Gulf coast of Saudi Arabia. Two parallel 3,050 metre long steel pipelines were to be installed under the bay. The smaller one to be used as an oil trunk line (24'') and the larger one with a total steel pipe weight of more than 1,500 tonnes will serve as a water injection line (30''). Previously published press releases claimed these as the ‘world’s longest undersea HDD crossings ever undertaken.
