Why Diamond Wire Is Much Used in Demolition Projects? - LinkedIn

What is an effective sawing solution to demolish bridges, stadiums, dams and other metal structures? We would say it is diamond wire according to our years of experience.

Diamond wires are engineered to use injected synthetic rubber and sintered beads. Synthetic rubber wire is very flexible, so it is easy to use and minimizes the risk of uneven wear to the wire beads. In construction sector, diamond wires function efficiently to demolish the toughest types of concrete, rebar and hard stones and have been proven well-performing in many demolition projects.

Diamond wires are usually seen in the demolition of concrete constructions. In fact, concrete is abrasive and hard by nature. It is a type of building material comprised of cement, water, aggregate and steel, so it is indeed not easy to remove large foundations and bridges, thick walls or oversized pipes simply with a circular laser welded saw blade.

On one hand, circular saw blades cannot cut through a large concrete structure because of their limited sizes; on the other hand, large circular saw blades are costly to fabricate. That is why diamond wire sawing is preferred in concrete demolition and removal. The innovative “pulling” movement of diamond wires delivers efficient result on crystallized or old concrete, steel encased concrete and heavily reinforced rebar.

There is another benefit to employ diamond wire cutting in many demolition instances, because water is utilized as a coolant and lubricant to avoid hazardous chemicals, sparks and dust, and operators are kept at a safe distance while operating remotely.

Use M16 chemical anchor bolts to fix the main tripod and auxiliary tripod of the wire saw. The guide wheels must be installed stably, and the edge of the wheels must be aligned with the center line of the rope hole to ensure the effective cutting speed of the cutting surface, strictly implement the installation accuracy requirements.

According to the determined cutting form, the diamond wire are wound around the driving wheel and the auxiliary wheel in a certain order. Note that the direction of the rope should be consistent with the driving direction of the driving wheel.

According to the on-site conditions, the connection of water, electricity, mechanical equipment and other related pipelines should be correctly standardized, relatively concentrated and placed, and the safety operating procedures should be strictly followed to prevent the chaos of many machines, many people, auxiliary equipment and materials, which may cause potential accidents. During the diamond wires cutting process, the direction of the wires movement must be protected by a safety guard, and safety signs should be set up in a certain area to remind pedestrians not to enter the construction area.

Start the electric motor, adjust the driving wheel lifting tension through the control panel, ensure that the diamond rope is properly tensed to supply circulating cooling water, and then start another electric motor to drive the driving wheel to drive the diamond wire rotary cutting. The stability of the frame must be closely observed during the cutting process, and the offset of the guide wheel must be adjusted at any time to ensure that the cutting wires are in the same plane.

During the cutting process, the cutting parameters are adjusted through the operation control panel to ensure that the diamond wires running line speed is about 20m/s. On the other hand, the amount of washing liquid should be ensured during the cutting process to ensure the cooling of the diamond wire and take away the grinding powder eyebrow. Cutting operation to achieve stable speed, stable parameters, stable equipment

Such as the occurrence of wires, broken wire and other phenomena should have corresponding measures to solve. Safety protection measures must be strict, otherwise the diamond beads on the broken diamond wires will fly out like a bullet and hurt people. Therefore, in addition to taking the necessary protective measures, the scene all refuse to observe unrelated personnel.
