Installing cables or pipes
Rook Services has a range of machines giving the capability to ram steel casings from diameters of 100mm up to 2000mm. The duct created can be used for smaller pipes or cables, allowing them to be routed under obstructions like roads, motorways, railways, rivers and canals.
Our ability to install a larger casing allows the duct to be used for more than one application giving our clients the opportunity to accommodate other utilities or generate revenue from other companies requiring the same facility! Capacity.
The casings can be rammed with open or closed ends. The closed configuration needing more thrust, but the inner surface of the casing is protected.
Where an open pipe is used the process is facilitated by fixing a ‘shoe to the leading edge of the casing. This reduces the pressure required, helps to maintain an accurate cut and decreases the volume of soil taken into the pipe, making the cleaning faster, which is done with high pressure air/water.
The principal benefit of pipe ramming is that the surrounding soil is not excavated, thus removing the risk of settlement and its potential impact upon buildings, roads and services. We find that ramming is successful where augers often fail. Small boulders are pushed aside or swallowed by the pipe and cleared by the final cleaning.
Our specially designed pushing hammers speedily and accurately install the new steel casing, without distortion. The process is a viable and cheaper alternative to large excavation work, causing little disruption to traffic and the local population whilst being suitable for all types of terrain, with the exception of solid rock.
