Advanced grouting system meets specification

As engineers write tighter and tighter specifications for grouting, so equipment manufacturers must develop solutions which can help contractors meet those specifications, and prove that they have met them Atlas Copco's new mobile grouting system, Unigrout Smart A, has been designed to do just that: it can mix, pump, monitor, log and control flow and pressure precisely. The control system allows on site mixing of a range of grouts as required by the project.

161 Atlas Copco's new mobile grouting system, Unigrout Smart A, has been designed to do just that: it can mix, pump, monitor, log and control flow and pressure precisely.

The control system allows on site mixing of a range of grouts as required by the project.

The quantities of water and cement are weightbatched and delivered to the coilloidal mixer, a type of mixer which uses a high velocity blade to shear or separate grout particles, breaking surface tension and enabling complete contact between the particles and the water. From there it moves to an agitator until it is called for by the pump.

The Unigrout Smart A has a dual-pump system. As well as its established Pumpac piston pump which controls pressure and flow independently it also has the facility to operate with a progressive cavity pump, a type of pump specified by US federal regulations for grouting.

The computerised recording system samples and stores flow, volume, pressure and pumping time from up to four lines at once. The information can then be transferred to a PC for reporting purposes.

The city of Coatzacoalcos is located at the mouth of the river of the same name, in the Gulf of Mexico, 302km from the city of Salina Cruz, Oaxaca, in the east end of trans-isthmian corridor and at the southern end of Veracruz State. The city is seeing a key development as currently construction is 85% completed on the first immersed tube, underwater tunnel in Latin America. The reasons why experts chose this type of tunne

    Greater precision is helping blur the boundaries between GIS technology and design software While GIS map based technology has extended its range across an ever more universal spectrum of uses in the highways sector, it is increasingly showing weaknesses for engineering purposes. It is very often not accurate enough. This has not mattered previously because the GIS tool has been seen essentially as an automated version of paper based systems from the design department's point of view. Where engineers
