-- Today, 24 feb., on my way to & from LOTUS-TESCO - Phahon Yothin rd., I stopped to see how these '
Post tensioned.' fly-overs support themselves? There is a rd.-tfc. fly-over being built across the Phahon Yothin:Chaeng Wattana i'sect.,
not too far from the previously mentioned MAX VALUE S'MKT. - Chaeng Wattana. As far as I could discover, and for those who might be interested, each concrete shape has projecting lugs on one end that mate with matching recesses in its neighbour, (this male & female business, once again!), - each series of shapes between adjacent & suporting pillars is then pushed tightly together so that that series becomes a self-supporting whole. Then rebars., or similar, are inserted into matching holes in the concrete section that's atop the suporting pillar and its immediate neighboring shapes for add'n. strength. Actually the whole process is a mixture of close-tolerance engineering and brute strength that relies on the use of sledge-hammers and/or club-hammers for fine movements!
-- Anyway, to a possibly MORE generally interesting topic: I had the feeling that if approached discreetly several of the laboring types, while
not of our persuassion or life-style and by
no means being eye-candy, but still interesting in their own way, might
not be averse to being Tops; (and, as many of us know, here in the LoS. being a Top does
not necessarily mean that one is gay, does it?),.
