Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, most commonly the legs. Nonspecific signs may include pain, swelling, redness, warmness, and engorged superficial veins.
Align with the centers of terminal posts. Now, dig the post holes (normally 6 wide and 18 to 24 deep) and set the line posts. Before concrete begins to set, adjust post height by carefully moving post up or down in footing. Top of line posts should be even with string; outside face approximately 1/4 inside.
Metal posts should have a coat of rust inhibitor. Dig a hole about three times the diameter of the post. Hole should go deep enough to encase one third of the length of the post (no more than 3 feet for most posts). If soil is loose or sandy, dig a larger, dish-shaped hole. Tamp the sides and bottom so that the hole walls are firm. You may want to use a QUIK-TUBEâ¢ Building Form. QUIK-TUBEs are rigid fiber forms for setting posts for projects like deck piers, patio footers, dock pilings, heavier fence post bases, etc.
