Tanzania SGR Bridges vs Kenyan

Ishu ni function yake, huwezi kujenga tunnel for the sake ya kujenga tu. Mchina anawajua akili zenu ndiyo maana amewajengea mivituo ya ajabu ili kuwapumbaza.

Hakuna tunnel yoyote yenye urefu wa 7Km kusini mwa Sahara, huo ni uongo wa wakenya kama kawaida yao, hao wameunganisha tunnels nyingi. Hapa kwetu zipo NNE, the longest ndio hiyo 1.2Km, ukiziunganisha zote nne zinaweza fika 5Km.

The second longest railway tunnel in Africa was on Monday completed after months of construction.

The SGR Ngong tunnel became the longest railway tunnel in East Africa and second in Africa.

It stretches for 7.41km which is second to the Hex River Tunnels in South Africa which stands at 13.6km.

The route runs from the Em-Bulbul SGR tunnel in Kajiado County and joins the Ngong one to complete part of the second phase of the SGR project.

The project takes the railway line from Nairobi to Naivasha and onward to Narok.

According to the Kenya Railways management, laying of tracks is the next step after completing the tunnel.

The Ngong tunnel has been designed as a single-track railway path with a clearance height of 7.6 metres and a width of 6.4 metres constructed using the three-bench seven-step excavation method.

Benching refers to the creation of a series of steps in the vertical wall of an excavation to reduce the height and ensure stability during construction.
Evidence? BTW that 4.5 km u claim is nearly 3 km less from 7.4km! That means if 7.4km was for all the tunnels in ur SGR then TAZARA with a combined 22 tunnels will be way longer compared to SGR Kenya.
We are not competing but clearly you guys are always on a losing streak when you try to outdo Kenya.
 
Which is which?

Works on Kenya’s first and longest railway tunnel at Em-Bulbul in Kajiado County will be completed in August, China Communications Construction Company (CCCC) has said.
The tunnel is on the 120-kilometre Nairobi-Naivasha route of the standard gauge railway (SGR).

The company’s spokesperson Steve Zhao said engineers were working round the clock to ensure that the section is completed in the next five months.

“So far 1.2km is complete from the exit end, 0.8km from the entry side of the tunnel and 0.5km from the mid-section. The construction is taking place simultaneously to ensure that we complete all the work within the stipulated time,” said Mr Zhao in a statement Wednesday.

The Em-Bulbul SGR tunnel in Kajiado County covers 4.5km and is the first of the three sections of the 7.14km SGR tunnel, the contractor says is the second longest railway tunnel in Africa.

The other two sections of the tunnel cover 1km and 1.64km.

These will be constructed along the Naivasha-Nairobi standard route at a total cost of Sh150 billion funded by the Exim Bank of China.

The construction of the line to Naivasha is expected to be completed within 2019, the company said.

Single-track line
The Ngong tunnel has been designed as a single-track railway tunnel with a clearance height of 7.6 metres and a width of 6.4 metres constructed using the three-bench seven-step excavation method.

Benching is the creation of a series of steps in the vertical wall of an excavation to reduce the wall height and ensure stability during construction.

The rocks are blasted to create the tunnel’s arch shape.

The construction of the Naivasha line started in January with the production of parts like T-beams and sleepers.

After the completion of the Nairobi-Naivasha line, it is expected that the line to Kisumu will be built at a cost of Sh350 billion.

The Mombasa-Nairobi SGR line was built at a cost of Sh327 billion.

Although the passenger services have picked up since launch in May last year, the government is firing on all cylinders to win the hearts of importers to get the right volumes on the rails to the Nairobi container depot.
