The project, which started in January , has developed an evaluation method to assess different trenchless replacement techniques. As a result, it is now possible to evaluate and compare different replacement techniques under a wide range of conditions. This opens the way to a decision-support knowledge database. The evaluation method has been tested in three fields trials in the project. Two evaluation reports have been produced, and work on the third is currently ongoing. The results to-date are published in a conference paper for the 12th Pipeline Technology Conference, to be held on May , in Berlin.

Sewer CIPP lining systems allow trenchless rehabilitation of deteriorating sanitary and storm sewer pipes by creating a new, fully structural pipe within the host pipe. The design prolongs the life of the filter bags and eliminates the threat of material entering the vacuum pump. Options include a cold-weather recirculation package, sludge pump, auger unloading system, body pressurization system, remote pendants and wireless remotes, high rail package, washdown system, stainless steel body and a high-dump option.
The Utility Air-Spade Series from Guardair Corporation harnesses the power of compressed air to safely uncover underground utility lines without harm. Its supersonic nozzle generates a laser-like jet that moves at twice the speed. It features a nonsparking brass nozzle and components, electrically insulated 4-foot barrel rated to kV and a lightweight, ergonomic handle.
A dead-man trigger ensures safe operation, and a trigger guard prevents accidental activation. A retractable stabilizer bar provides superior operator control. An integral pressure gauge ensures optimal digging performance. The degree rotating front-mounted reel facilitates easy unit placement.
Reel capacity is designed and engineered for up to feet of 1-inch hose. The top-loading boom powers up and down and extends to 26 feet from the pivot point. The single-engine drive dramatically decreases fuel consumption, maintenance expense, weight on the chassis and the initial chassis price. The water pump consists of a continuous flow, triplex reciprocating design and is rated up to 80 gpm at 2, psi.

An optional unloader valve allows for complete control of water flow and pressure independent of the vacuum power. Tanks are constructed of high-strength, UV stabilized polyethylene, with optional fixed internal baffled aluminum tanks. It comes with a redesigned hydraulic system that provides super-fine touch and improved controllability. It features the Hi-mate Remote Management System, which allows operators and dealer service personnel to access vital service and diagnostic information from anywhere with internet access.
It boasts a bucket breakout force of 49, pounds, a maximum dig depth of 27 feet, and a 1. They eliminate tracks by utilizing zero-turn technology for access to tight locations and lawns. Weighing only 2, pounds, they feature an 8-foot digging depth and 6,pound digging force. The unit features a 7-footinch loading height with a swing radius of degrees, allowing access next to walls and other obstructions. An auxiliary hydraulic tool circuit has the ability to power hydraulic tools including jackhammers, pumps and saws. The tool has a 1-inch water connection.
The operator controls water pressure and power with truck controls. Features include 6-foot Tuff Tube with handles fabricated to the tube to guide the unit down for potholing or side to side for trenching.
Six jets boring inward cut the soil, while six jets boring outward bring the tube down. Bumpers on the bottom protect the jets and lines the tool might contact. It can deliver up to 18 gpm of flow and 3, psi of pressure, while its 8-inch positive displacement vacuum system provides airflow up to 5, cfm and 28 inches of vacuum to ensure the thorough removal of a wide variety of materials. An ejector plate system smoothly pushes the load out of the collector body and into the disposal site.
It has the ability to raise and tilt its collector body to unload into disposal areas with barriers or berms. The F4 hydrovac unit from Tornado Hydrovacs carries 13 cubic yards of mud and more than 2, gallons of freshwater. Components include a water tank from which you excavate, a mud tank in which the excavated spoils are held, a water pump, a boiler to heat the water and a positive displacement vacuum blower to pull the spoils to the tank via a boom. The X-Cavator from Vac-Con is available in configurations from 5- to cubic-yard capacities, with hydrostatically driven three-stage centrifugal compressors.
A variety of hydrostatically or mechanically driven positive-displacement blowers up to inches Hg are also available.

It can also be configured with dual positive-displacement blowers with airflow up to 7, cfm. Low-volume, high-pressure water systems with up to 4, psi are available with cross-linked polyethylene water storage tanks with up to 1, gallons of capacity. It is available with a Power Flex Boom that extends up to The boom articulates up to degrees and will lift up to 34 feet into the air. Booms are available with up to a foot extension, and 8- and inch tube diameter. The Vacall AllExcavate hydroexcavation truck features a high-dump option that allows the operator to use a wireless remote control to raise the debris tank as much as 76 inches above ground level, and then shift the tank horizontally 21 inches beyond the rear bumper.
It uses just one engine for mobility and to generate water flow at 10 to 25 gpm and pressures up to 3, psi. Used in combination with strong vacuum, it can loosen and remove dirt, rocks and other material from around utility lines and foundations. Standard and optional debris bodies and water tanks are available. The AllSmartFlow CANbus intelligent control system is standard, monitoring water usage and minimizing downtime for water tank refills.
Its streamlined design features no external air tube and is stabile in the pipe due to its pound construction from a solid billet of stainless steel. The head assembly incorporates a pinionless, quick-change design and only one adjustable gib. Lateral reinstatement is achieved with the 0. It can be disassembled and reassembled in approximately 30 minutes due to its eight-moving-parts design.
All the electric motors are isolated at the end of the cutter in a watertight chamber, eliminating water-damaged motors and allowing for easy and quick access. It is manufactured from temper-hardened stainless steel and bronze. HydroCut and self-propelled milling robots from IBG Hydro-Tech feature milling arms equipped with a camera TV lines that can rotate degrees.

They also feature improved high-resolution LED lighting, allowing users to gain a better perspective on precise work. It has a hydraulic feed-through for high-pressure water up to 3, psi with a slip ring on the milling arm that increases mobility, making it swiveling endless. The Utility chainsaw from ICS - PowerGrit addresses operator safety with grinding technology that eliminates rotational kickback and offers improved operator positioning when cutting pipe.
Utilized by public and private water and wastewater departments worldwide, it is designed to cut a variety of materials from ductile iron to plastic pipe with far less excavation. The ability to cut up to inch pipe without changing position reduces the difficulty of the job.
