Diamond wire sawing represents a cutting procedure utilising metal cable or wire with synthetic diamonds embedded within beads that are attached at regular intervals along the wire to facilitate the cutting. These beads are approximately 11mm wide, slightly wider than the actual wire. It is the beads, more specifically the diamonds embedded within the beads that performs the cutting.
The wire is threaded through a series of pulley’s including pulley’s mounted in specific location to achieve the precise cut line desired. A continuous loop is formed. Via the use of hydraulic or more recently hi-frequency electric driven powers sources, the wire is tightened and then pulled through the network of established pulleys and along the target material. As the beads attached to the wire are pulled under pressure the target material is cut. This process is continued, with the wire remaining under pressure and continually tightened until the cut is complete.
The length of wire required will depend on the size of the object being cut, noting that the length can exceed 50 metres and beyond.
Where access to all sides is not available, small feed holes are drilled to allow the wire to be fed through and around the material to be cut.
Advantages of Wire Sawing
With wire sawing there are no limits to sawing depth. Wire sawing is ideal for removing large pieces of solid objects where other concrete cutting equipment either cannot reach or is unable to achieve the width or depth of cut. For example, wall sawing is capable of cutting to a depth of 1000mm, after which the wire saw must be used as it can cut significantly deeper.
Wire sawing results in precise, accurate cuts, leaving surfaces smooth and clean on completion. No further surface preparation is required post wire sawing due to the smooth edge achieved during the wire sawing process.
Wire sawing has the ability to cut in any direction, along walls, floors, as well as inverted. In addition to this wire saws are able to cut virtually any shape or size within the structure being cut. Amazingly wire sawing can also be used to cut circular penetration of differing sizes.
Wire saws cut through virtually any material, from very thick concrete, masonry or stone, heavily reinforced concrete to solid steel structures including concrete encased steel pipes.
Wire sawing represents an environmentally friendly concrete cutting solution with minimal noise, or vibration as well as reduced dust via the use of water as a suppression system. This advantage allows for wire sawing to be performed in close proximity to occupied spaces.
Wire sawing is extremely flexible and versatile, a perfect solution for cutting underwater, or hard to reach awkward locations.
Wire sawing also represents an extremely efficient cutting method. Whilst the initial setup is longer than other concrete sawing and drilling services, once established, the actual cutting time is very fast. Wire saws can also be set up to perform multiple cuts in close proximity at the same time.
Planning, engineering, and creativity allow multiple cuts to happen simultaneously, which can reduce cutting time.
In summary, wire sawing represents a unique cutting methodology that allows it to execute tasks that traditional concrete cutting equipment cannot achieve.
Wire Sawing applications
Saw cutting very large, thick sections of concrete such as those found in bascule piers, dams and power or manufacturing plants.
Cost effective for cutting large sections of heavily reinforced concrete such as bridge sections, machine bases, piers and concrete encased steel pipes.
Other applications include cutting under water or other restricted or difficult work environment, as well as objects too large for other concrete cutting equipment.
