Fantabulous pics

Noice!

Robert Alai ana bahati kama mtende, juzi on his FB post regarding the photoshop ya SGR I tried to upload this pics ika kataa kapsaa

Alai ni mtu mzee lakini akili hana.

hizo pilars zimeingia kwa maji ziujengwa aje

Nkidhani in some instances they divert the water flow… Ivo ndio nimeona wakifanya pale Huruma rounda

A combination of water and earth bending.

Huwa haziguzi chini…Incase hiyo ndo unafikiria…

Zinawekwa Floaters…So anytime unapitia lets say Nyali bridge kuwa ukijua unafloat tu…

To Assault your Mind More…Did u know that even the sky scrappers swing kulingana na strength ya wind??? If u didn’t know, now u know…

The pillar is casted away from the site then brought in pieces and joined using beams

sounds reasonable

wewe inaonekana unanipima bangi ati haziguzi down ???

so its safe to say they aint that stable?

Am sure they have a firm base si at I wanaekelea tu kwa maji

Only for very deep waters and not in such a river

Bado sijaona or read about floating bridge piers.
On construction, kuna methods kadhaa, hiyo @Mzee mzima ame mention hapo juu inaitwa coffer dam. create a temporary dam for blocking off water in case of a lake or for diverting water incase of a river.
Another method is to use a big hollow cylinder, pump out water and excavate, to the depth require, you will have a dry place to work within your hollow cylinder.
The simplest is to assume maji haiko, excavate the hole in the presence of water, but when it comes to pouring concrete unatumia tremie. This ensures only a small bit of the concrete being poured will come in touch with the water which will be eventually wasted when you finish pouring

(huyu jamaa anasema zina-float inafaa ajue sio zote hufloat… depends on the design considerations, engineering is not a joke…!!)

One way is, they wud do is get a hollow tube, insert it in water, pump out the water and then, then work on the surface bed.

Another is, make it pre-cast, then u come and hammer it while on site up to required depth.

kuna njia zingine but those are the main ones…
