Wire Sawing Case Studies

Increasing a swimming pool depth:
Using the 3 Phase wire saw in conjunction with other equipment we use to provide a service, we were required to increase the depth of a swimming pool by 200mm, this involved slicing the area of floor to be removed into pre-determined sizes using our floor saw (or Slab saw),the wire saw was then used to under cut the slabs to release them from the floor, once they were free and the cutting complete they were simply lifted from the pool and placed in a skip. This method saved not only a considerable amount of time but as it is vibration free there was no risk to operatives or structural damage to the pool or surrounding buildings it also reduced any breaking out to a minimum massively reducing HAV (Hand Arm Vibration). Once the work was complete and the blocks removed this left a floor slab good enough to prepare and lay tiles.  Previously any similar work would have meant labour intensive, time consuming breaking out using either mechanical or hand breakers, this method is quicker, NO vibration and required no making good when the work was complete. Work completed in 3 days.

 

Removal of 23 Tonne plinths using Wire Sawing

Reinforced Concrete Plinth Removal:
As part of a concrete re-modelling programme we were approached to remove 4 concrete plinths from within a building which was 6 Metres below ground level.

The plinths were 3 metres x 4 metres x 800mm high, they were required to be removed flush to the floor so a new smaller plinth could be cast in its place. The plinths were cut into 3 sections each weighing approx 6.5 Tonnes
Due to its sensitive, restricted location breaking out was not an option due to the excessive dust which would have been generated which in turn would have damaged the equipment around the work area. 
The work area was screened off with approx a 1.5metre work area around the plinth, this was also required to be water tight to prevent slurry seeping under the sheeting and drying which could turn to dust. Due to the restricted nature of the work we were required to mount the Wire saw on top of the plinth and set up the pulleys so the wire cut under the plinth whilst the wire saw was on top. 2 vertical cuts were carried out to reduce the plinth into 3 sections, these were then lifted to ground level and disposed of, once the plinth was removed the floor area was left completely flat with no requirement for any further work to clean the area.
