road closure in kl city centre
The line in Kuala Lumpur is currently in progress.
In the next two weeks, the variable density tunnel boring machine (TBM)
Will Cross under Jalan Sungai Besi, the main gateway connecting downtown Kuala Lumpur and other suburbs.
The sections currently being mined are mainly composed of weathered limestone formations.
Weathered limestone is a geological structure known for its complexity and inherent challenges.
This complexity may lead to the above
The ground sinkhole, which will inadvertently lead to unplanned road closures.
Datuk Ubull Din Om, general manager of Gamuda Engineering, said: \"While the TBM has been equipped with equipment for challenging terrain, further measures have been taken to protect the public from any adverse events
\"One preventive measure is ground treatment, which is carried out step by step before the ground survey shows the arrival of the abnormal TBM.
\"Ground treatment involves pumping a large amount of concrete/mortar to the underground target area before mining to strengthen the ground.
This will give a greater stability to the boring machine because it is mining solid concrete blocks rather than natural sticking elements of weathered limestone, which may be unpredictable and not good for mining operations.
However, not all areas can be reached for ground treatment works, thus creating hidden risks.
\"In addition to more intensive monitoring of the TBM during the process through these highly sensitive areas, a team has been formed to conduct on-
Ground monitoring 24/7.
\"The team is called \'Niu gang\' and consists of people who are constantly looking for the smallest inconsistency on the ground.
\"Bull gangs patrol on foot, allowing immediate investigation and action to deal with the ground in a timely manner,\" Ubull said . \".
Despite extensive soil surveys and ground treatments, the risk of road subsidence or the occurrence of sinkholes cannot be completely ruled out.
As an accident, Jalan Sungai Besi will close the lanes in stages between now and August 10.
Planned closures covering 13 lanes will be staged in two weeks.
However, in the event of any emergency requiring a full closure of traffic, the closure of the road will be announced immediately.
From August 28-10, the second TBM will pass through Jalan Sungai Besi along the same path.
Therefore, the same lane closure will be implemented.
Road users are advised to use alternative routes to Jalan Istana, Jalan Tun Razak and Seremban during peak hours to reduce traffic construction
Within two weeks of the intersection of each machine with Jalan Sungai Besi.
