Product installation Important Points:

DOUBLE CORROSION PROTECTION ANCHORS / DCP BOLTS manufacturers exporters in india punjab ludhiana View

(1) Anchors Reception
- Check all anchors and components for possible transportation damage.
- Do not use anchors that have been bent or that have any surface damage.
- Do not use bars as ground for welding, do not allow hot slag to touch the bars, and do not weld to bars.
- Handle anchors with care using nylon lifting slings. The bars must not be dropped, thrown or dragged.
- Upon unloading, protect the bars from dirt and mechanical damage.

(2) DCP couplers in the bond and free lengths.
- Grease both bar ends thoroughly.
- Install coupler, bar ends must be centered inside coupler.
- Torque bar against each other
- Grease coupler thoroughly.
- Install heat-shrink sleeve.
- Important: do not burn the heat shrink sleeve nor the plastic sheathing.

(3) Grout tube and outer centralize assembly.
- Install outer centralizers within the bond length using adhesive tape and / or wire at the required spacing.
- If applicable, install grout tube using adhesive tape. The grout tube must start 50 to 100mm from the bottom of the anchor and extend at least 1 meter above the anchor head.

(5) Grouting of the anchor, installation of the trumpet & anchor nut
- Ensure that the anchor is centered in the borehole.
- Leave enough bar protruding behind the plate for the anchor nut and the stressing coupler (typically 500mm).
- Also ensure that there is sufficient bare bar inside the sealing tube of the trumpet to allow for free movement during tensioning of the anchor (typically 150mm).
- Grout the entire anchor is one stage according to the product specifications.
- While the grout is still wet, wash out 1.0 meter below the location of the anchor plate.
- Install the trumpet pre-filled with anti-corrosion compound over the bar, ensure the sealing tube is correctly engaged over the smooth pipe (bondbreaker) and the sealing ring of the corrugated pipe.
- Fasten anchor nut tight against the bearing plate.

(7) Protective caps installation.
- Pre-fill the cap with anti-corrosion compound.
- Install it over the anchor nut with corresponding seal (O-ring).
