One spot of MK-MT gas piping jobs is HDD Ciliwung Lama-Lodan along 420 meters. If any root of HDD Gas Piping is 6 meter, then number of roots approximately 70 roots. Since HDD Ciliwung Lama-Lodan began a week ago: mobilization tools/equipments and materials, setting of tools, Reaming 18 ', Reaming 24' and are currently ongoing Reaming 32 '. Actually, Thursday yesterday (05/19/2016) at 16:00 pm, Reamer 32 ' gas piping has appeared in the pit
entry for the first time, but the plan will be implemented process Ramming 32' as much as 3 to 4 times.
This step was taken to facilitate the process of pull back, avoiding stagnation. That Thursday, HDD Ciliwung Lama-Lodan get visits of

According to PM of PT Line Inter Cikara (Heru Widaryono) that HDD Ciliwung Lama-Lodan , when pull back will be using the machine HDD Vermeer D220 x 300 which is able to pull the strings of gas piping weighing 110 tons. Keep in mind, if the weight of the gas piping 24 'size of 12 meters is 2, 4 tons, then 420 meters: 12 meters = 35 pcs gas piping, then 35 pcs x 2.4 tons = 84 tons. So the use of Vermeer D220 x 300 is appropriate. Meanwhile, today in the implementation of the reaming 18 ', 24' and 32 'still using Vermeer D130 x 150 it maximal strength is 65 tons. Number symbol in front of the machine Vermeer is to show the maximum power in case of withdrawal or pull back of gas piping, for example: D 130 x 150 maximum strength was 130: 2 = 65 tons, while Vermeer D220x300 maximum strength is 220: 2 = 110 tons.

It is expected tomorrow (Saturday, 05/21/2016) can be done immediately pull back, if the rate of rotation reamer 32 'is normal, not *high. Spot of HDD Ciliwung Lama-Lodan located on land owned by Kodam Jaya (The Jakarta Military Detachment Supplies-Benglap) at Road Tongkol Penjaringan North Jakarta Indonesia.
