Installing the T-Head Mooring Bollard Cast-in Anchor
Release time:2024-04-15 Click:42
Taidun Marine Company offered the T-Head Mooring Bollard has two mounting options: it can be surface mounted, or recess mounted. Recess mounting is generally recognized as superior, as recessing the base prevents the bolts from working loose. In either case, the bollard is fixed with anchors—either cast-in or using epoxy and resin.
For a cast-in anchor installation, steel reinforcements must be provided and should be reviewed by a site engineer or technician with appropriate knowledge of the site’s requirements.
ANCHOR INSTALLATION
1,Anchor installation should be carried out by qualified personnel and under the supervision of the person responsible for technical matters of the site.
2,Anchor installation should be in accordance with the manufacturer’s specifications and drawings.
3, Use anchors which are supplied by the manufacturer or as per the approved drawings.
4,Check the strength class of the concrete in which the anchor is to be installed.
5,The concrete base must not have any significant voids.
6,The anchorage depth must be marked.
7,The edge distance and spacing should not be less than the specified values as per the bollard manufacturer’s calculations.
8,The anchor hole should be hammer-drilled with a diamond core drill bit.
9,If the drill hole is aborted, the hole should be filled with mortar.
10,For an overhead installation, piston plugs must be used. Embedded metal parts must be fixed during the curing time, e.g. with wedges.
11,For injection of the mortar in bore holes ≤250 mm, piston plugs must be used.
CAST-IN ANCHOR INSTALLATION
Anchors need to be installed at their designated position before the concrete is poured. Steel
reinforcements have to be provided to the anchors.

Step 1. Mark embedment length on all anchors used for each bollard.
Step 2. Use two anchor templates to locate and align the anchors vertically straight.
1,As shown in the image, place one anchor template on the head of the anchor and fix another template below the marking of the embedment length.
2,Restrain the top template temporarily to avoid any movement.
3,Reinforce the anchors with steel bars,The reinforcement design can be carried out by a jetty designer.
Step 3. Start pouring the concrete as per the instruction of the supervisor.
Caution:
In the case of a recess mounted bollard, use a cover boundary to stop the concrete being poured on the required recess for the bollard.
Step 4. Provide enough time to cure the concrete.
Caution:
1,Do not touch the anchors until the desired curing time required for the concrete has passed.
2,Check the required protrusion height of each anchor.
Step 5. After pouring, use the template to check the final anchor locations as per the relevant drawings.
