Week 39 – Hanuka 🕎and Tel-Aviv Light rail 🚅

Hi!
Week 39 – Ima said that I was born in week 42, and Atzva will also give birth late. She is suffering and wish it will be over =/. You have Christmas and New year and we have Hanukkah, the holiday of lights. So eat a lot of Sufganiyah, Singing the songs of Hanukkah and light up the Chanukia (which has 9 candles, one for each of the eight days of the holiday plus one to lit them up. Not to be confused with the Menorah which has 7 lights, one for every day of the week).

Our Chanukia during the nights. Each day of the holiday you add a candle till you finish with 9 candles 

Except that – I had a tour to the construction site of the TBM of Tel-Aviv Light rail . Those are being built inside a shaft in middle of the city. They are hugh, and reminds me the worm that was in The Wonderful Wizard of Oz, eating the ground as it goes forward and making a tunnel behind her.

The Tel-Aviv Light rail TBM model. The drilling head is just a small part of the machine, which contain another 12 wagons.

The site is on Ayalon Highway and Ramat Gan Daimond Exchange district– Tel-Aviv Light rail

The Jack part of the TBM. And if you wonder if how it takes the turns: it just push more on one side than on the other Tel-Aviv Light railThe Jack part of the TBM. And if you wonder if how it takes the turns: it just push more on one side than on the other

The most expansive part of the TBM: The engines. In the case the part gets broken, you have to dig a shaft and takes it out! Tel-Aviv Light railThe most expansive part of the TBM: The engines. In the case the part gets broken, you have to dig a shaft and takes it out!

Going down the shaft

The living wagon. 25 people will be on this machine ones it start working, they will have to pee somewhere.

Archimedes’ screw inside the machines, those taking out are the dirt from the bottom of the drilling part and load the small wagons that takes the dirt outside the tunnel.

The shaft from side side - Tel-Aviv Light railThe shaft from side side. The line will have two parallel tunnels. From this shaft four TBM will start drilling: two in each direction. Even on TBM is too big for this shaft, this is why they will start drill and wagons will be added as the machine progress into the tunnel.

The huge drilling head – 7.5 meter in diameter.
