Shipworms (Teredolite) are wood-boring bivalves that burrow deeply into submerged wood. [7] Although piles attacked by shipworms may appear sound on the surface, they may be completely riddled with a maze of tunnels. [6] Shipworms can spread to new wood only when they are in the free-swimming larval stage. [8]
It is often sought for construction projects in parts of the Caribbean, where wood ants are problematic in conventional pine wood construction. It was also used to build the dock gates in Liverpool, such as the Manchester dock gate. It has been used extensively as marine piling, since it is highly resistant to marine borers. It is also ...
In falconry, a mews is a birdhouse designed to house one or more birds of prey. [1] [2] In falconry there are two types of mews: the freeloft mews and traditional mews. Traditional mews usually consist of partitioned spaces designed to keep tethered birds separated with perches for each bird in the partitioned space.
When free hydroxyl groups are transformed to acetoxy groups, the ability of the wood to absorb water is greatly reduced, rendering the wood more dimensionally stable and, because it is no longer digestible, extremely durable. In general, softwoods naturally have an acetyl content from 0.5 to 1.5% and more durable hardwoods from 2 to 4.5%.
Every part of the tree is used in both raw and finished states. Its timber and nuts are used extensively. The bark is used locally to produce rinses or enemas for loin pains or kidney problems. The wood is used to make pilings for bridges and railway ties in addition to charcoal and standard construction.
Bird scarers is a blanket term used to describe devices designed for deterring birds by startling, confusing or otherwise repeling them, typically employed in commercial settings by farmers to dissuade birds from consuming and defecating on recently planted arable crops. Numerous bird scarers are also readily available to the public direct to ...
Wood pilings grouped into a pair of dolphins serving as a protected entryway to a boat basin. A dolphin is a group of pilings arrayed together to serve variously as a protective hardpoint along a dock, in a waterway, or along a shore; as a means or point of stabilization of a dock, bridge, or similar structure; as a mooring point; and as a base for navigational aids.
When less expensive or more readily available than wood, steel T-posts or star posts are used, usually alternating every 2 to 5 steel posts with a more stable wood post. Non-electrified wire is attached to wooden posts using fencing staples (for intermediate posts, these are fitted loosely, not gripping the wire).
