Why is concrete diamond wire saw ropes Better?

Concrete is a construction material with incredible compressive strength used to build everything from streets and sidewalks to industrial and commercial buildings to bridges, dams, and piers. When construction and renovation projects involve concrete in its various forms, in most cases, the planning and executing of the project will require removing, altering, or cutting concrete in some way.

A diamond wire saw is a type that rotates cable strung with diamond-embedded beads. The cable and beads are coated with a thin layer of rubber, which contributes to durability, particularly in wet or marine environments The entire strand of cable, beads, diamond chips, and coating is known as &#;diamond wire.&#;

Due to its appearance, it is often referred to as &#;rope,&#; giving rise to the industry term &#;rope sawing.&#; The diamond wire is run through wheels and pulleys on the saw, allowing the operator to adjust tension, speed, and cutting depth.

When most people think of saws, they picture a bandsaw or reciprocating saw. The diamond wire saw is different. Rather than operating with a fixed blade, a diamond wire saw accomplishes the cut by looping the diamond wire around the object to be cut or threading the wire through a core hole to achieve the required loop configuration.

Using Diamond Wire Saws to Cut Concrete

Diamonds are one of the Earth&#;s hardest substances, which is why they are an effective tool for concrete cutting and other hard materials, including metal. Beyond the obvious advantage of diamond wire cutting through concrete, diamond wire saws are ideal for this work for several additional reasons.

Speed

Cutting through concrete with some tools can be a slow, tedious process, but diamond wire saws work in a way to expedite the concrete cutting project. 

Versatility

These saws can be configured in various ways; they operate underwater, suspended in the air, and in a wide range of temperatures and weather conditions.

Tight Space

Because diamond wire saws are configured on the job to suit the job, they can be used in locations with limited space and access. The operator, control panel, and power supply can, and often are, positioned a distance from the object being cut.

Precision

Rather than using explosion as a tool on the concrete demolition job, you can make precise cuts with diamond wire saws and segment the object into pieces sized for removal. 

Minimal Vibration

These saws operate with minimal vibration, allowing them to be used on jobs where adjacent concrete structures might be damaged by vibration. 

Minimal Dust

There are several techniques for minimizing and capturing the airborne effluents created by diamond wire concrete cutting, including HPV vacuums set up at the point of contact and sunning water on the wire at the cut site.

Durability

A significant benefit of diamond wire saws is their inherent robustness and durability. These saws can withstand punishing conditions, including marine climates and extreme temperatures. Because they are durable, downtime is rare, making diamond wire saws a cost-effective concrete-cutting option. 

Safety

Using a diamond wire saw is safe for the operator and other people on the job site. A cutting plan created to minimize breakage and chipping is always a preferred option. These saws also produce less noise and dust than other concrete-cutting options.

These are all safety issues. Too much noise can damage hearing and lead to accidents from other hazards. Also, dust from concrete is a known health hazard and, consequently, something to avoid. 

Concrete Applications for Diamond Wire Saws

Diamond wire saws can easily cut through hard materials and are the preferred choice for cutting through the toughest items, like concrete, masonry, rebar and other metals, and stone. Wire saws are the best option for cutting objects flush with an existing structure or in situations with restricted access, such as beyond narrow doorways and corridors and tight quarters such as hydroelectric dams, ships, and nuclear facilities.

Various industries have a frequent need for concrete cutting using diamond wire saws. These include the heavy civil, heavy industrial, nuclear, and offshore industries. Other industries use this tool and these cutting processes for decommissioning and precision demolition solutions.

Examples of Concrete Cutting Projects Using Diamond Wire Saws

Here are a handful of examples of large-scale industrial projects that Bluegrass Bit Company has completed over the years using diamond wire saws.

Gross Reservoir Dam Expansion

In Project Phase 1 of Denver Water&#;s Gross Reservoir expansion project, Bluegrass Bit helped remove the dam&#;s ogee crest, which measured 160&#;L x 28&#;W x 13&#; H. After drilling 4&#; wire access holes, we used diamond wire saws to cut vertical slots and then horizontal cuts into the dam to remove 20,000-60,000 lb. blocks for removal.

Humboldt Bay Nuclear Plant Decommissioning

Due to seismic concerns, PG&E needed to remove a 250&#; ventilation stack at the Humboldt Bay Nuclear Plant. Operating on an elevated platform, Bluegrass Bit removed large ring sections of the ventilation stack using diamond wire saws and cut the concrete into smaller segments for disposal.

Tallulah Falls Dam Plug Removal

The Tallulah Falls project involved cutting and removing a plug in the dam face for a new pipe insertion. Using a crane, Bluegrass Bit cut and pulled the plug using a diamond wire saw. We then cut the removed plug into smaller pieces of manageable dimensions.

Hydromill Rescue in Boston

A construction company&#;s hydromill became inoperable and wedged 70&#; underground during the winter in Boston. The company turned to Bluegrass Bit for assistance. The equipment was wedged against an I-beam. Our team used diamond wire saws to cut through an adjacent concrete wall, providing access to the I-beam for safe removal.

When diamond is used to cut buildings, it is called non-destructive cutting, also called non-destructive cutting and demolition engineering (technology). This technology mainly uses a running motor to quickly drive the drive shaft and flywheel to make the wire saw produce linear motion. Through the backward pulling force, the diamond  wire saw bead is used to grind and cut the object, and finally complete the hard material. During the cutting process, the whole process will not produce a lot of dust, noise, and will not cause destructive hazards to the geology and the ground, so this technology has become a new type of environmentally friendly and efficient new type of static cutting and dismantling. Construction methods.

However, the steel-concrete cutting wire saw is limited by the hardness of the cutting object, especially when the steel-concrete structure has thicker steel bars, it has a huge impact on the cutting performance and life of the wire saw, and the requirement for cooling water is very important. There are many specifications and instructions for the motor power of the wire saw machine, the placement of the flywheel, and the safety requirements. This article introduces these points of use, so that everyone can better use the diamond wire saw. The three aspects of stability and accuracy enhance the use value of wire saws and make wire saw cutting more convenient.

1: Safety is more than everything. The wire saw for cutting steel mix consists of three parts: bead, wire rope and rubber connector. Beads serve the purpose of cutting, while wire rope and rubber connector are used to fix the beads. In many cases, In the cutting process, especially in the process of cutting steel mix, when cutting the small face or cutting to the final finish, due to the small cutting surface, the bending angle of the wire saw is reduced. During the cutting process, the rope may be stuck. Once the rope is stuck, if the motor is still allowed, the beads will loosen. Once the beads are loose, the cutting effect will not be achieved. And because the beads are loose, there will be local excessive force and the beads will be  fall off and fly out, even if the beads do not fall off, this situation will continue for a long time, and it will cause the rubber and the hard material to start rubbing against each other. When the rubber is ground, the wire rope will become prominent, and finally the wire rope will start to interact with each other. Hard materials create friction and eventually break the rope. In this process, the safety issue of the use of the wire saw is also posed: how to make the wire saw safer?



Therefore, during the construction process, no one is allowed to enter within a radius of 25 meters in the running direction of the wire saw, and no one is allowed to enter within a radius of 15 meters in the opposite direction allowed by the bead. There are also several precautions during the cutting process. For example, when it is required to cut small surfaces, try to replace the discarded wire saw for cutting to avoid premature bending of the rubber and wire rope in the new wire saw, and avoid loose beads and jams. In the cutting process, remote control is used to complete the cutting work, and the stability of the cutting is judged by sound and motor current.

2: Fast cutting is very important. In the process of cutting steel concrete, Lin Xing&#;s engineers found that the more efficient the product, the chance of jamming and breaking the rope will be greatly reduced. In fact, the reason is very simple. In the process of cutting, the high cutting efficiency of the wire saw represents high sharpness. In the cutting process, once the cutting is blocked, the sharp bead can quickly cut the materials on both sides through the high-speed linear speed, thereby alleviating or removing the blockage. However, the slower beaded rope cannot cut the jammed stone well, which increases the possibility of many negative factors in the cutting process.

There are two main parts to improve the cutting efficiency. The first motor power, the use of a large motor can quickly complete the cutting, this is a very simple reason, the second part is the efficiency of the wire saw, which mainly needs to be equipped with a higher sharpness product.

3: Accurate cutting is the most important requirement for wire saw work. If you have been in the concrete cutting industry, you will find that if the wire saw is jittered, the life and efficiency of the wire saw will be greatly shortened, so adjust the cutting angle of the wire saw  and the position is particularly important: Simply put, if the flywheel of the wire saw and the wire saw machine is adjusted, the wire saw cutting is more convenient, the linear cutting force of the wire saw is greater, and the pulling force of the wire saw is better. The application of this to the cutting surface requires constant experimentation and adjustment. The core point of accurate cutting lies in the placement of the wire saw. The placement of the wire saw machine and flywheel, measuring with an angle measuring instrument will make the wire saw cutting more convenient.



4: The size of the water flow is also a very important point in the process of cutting steel concrete with a wire saw. If the water flow is too large, the beads will slip, which will reduce the cutting efficiency. However, if the cold water flow is too small, the water flow will not rise during the cutting process. The effect of cooling and chip removal is also greatly affected, which is likely to cause the secondary cutting and polishing of the wire saw and waste materials.

5: Stability is the core point of wire saw cutting. It mainly judges the stability of the wire speed of the wire saw during the cutting process, the stability of the motor current, the stability of the machine base during the cutting process, and whether the deviation of the guide wheel is stable etc. Once these areas remain stable, the process of cutting the steel mix with the wire saw is stable.

In general, the process of cutting reinforced concrete with a wire saw is a job of carefully observing the cutting process, paying attention to changes in water flow and speed, and maintaining stable cutting while ensuring safety. The cutting points are nothing more than taking many details into consideration to achieve a more detailed, more standardized and data-based experience summary.
