🚇 Purple Line Tunnel Repairs Near Wongwian Yai Could Take Up to 12 Days 🚧

There's some encouraging news from the Purple Line construction site near Wongwian Yai. 💜 Engineers say the situation is becoming more stable after a water leak caused the ground above the tunnel to sink.

📍 What Happened?

A leak inside the southern Purple Line MRT tunnel caused the road above it to subside (sink), raising concerns around Wongwian Yai intersection. 🚧

The road has now sunk about 28cm (up from just over 20cm the previous day), but the good news is that the sinking has slowed significantly. 📉 Engineers say this is a positive sign that the ground and tunnel are beginning to stabilize. ✅

🏢 Nearby buildings have also shown no new signs of tilting or movement, giving officials more confidence that the area is becoming safer.

⏳ How Long Will Repairs Take?

Repair work is expected to take 7 to 12 days. 🗓️

To speed things up, construction crews have brought in:

👷 More workers
🚜 Additional machinery
🏗️ Extra equipment

Their main priority is filling the underground gaps where soil was washed away to prevent any further sinking. 🕳️➡️🪨

Officials are also asking for permission to remove a nearby pedestrian bridge 🚶‍♂️🌉 so larger construction equipment can reach the site more easily and repairs can move faster.

💧 Why Can't They Just Pump Out the Water?

It might seem like the easiest solution—but it's actually much more complicated. 🤔

The tunnel is surrounded by groundwater, and the water inside the tunnel helps balance the pressure from the outside. 🌊⚖️

If engineers pumped all the water out too quickly, the tunnel could become unstable and make the situation worse. 😬

Instead, they're following a careful step-by-step plan:

1️⃣ Fill the underground voids around the tunnel.
2️⃣ Stabilize the surrounding ground. 🪨
3️⃣ Slowly reduce the water level. 💧
4️⃣ Find and repair the exact source of the leak. 🔍🔧

Deputy Transport Minister Siripong Angkasakulkiat explained that engineers still don't know exactly how large the leak is because the tunnel remains full of water. 🚇💦

🏢 Buildings Are Being Monitored Around the Clock

Safety remains the number one priority. ❤️

Officials are checking nearby buildings every 30 minutes ⏰ to monitor for any movement.

So far, all measurements remain within safe limits and continue to show an improving trend. ✅📊

💰 Who Will Pay for the Damage?

The government says the contractor will be responsible for any damage caused by the incident. 🏗️💵

During the repair period, the contractor must also support residents affected by:

🏠 Evacuations
🚧 Road closures
🚶 Restricted access around the site

Details about compensation will be announced later, but officials have assured residents that assistance will be provided. 🤝

🌍 Thai & International Experts Called In

The incident has also raised questions about construction standards on the Purple Line project. 🏗️

To ensure a thorough investigation, the Transport Ministry has invited both Thai and international engineering experts 🌏👷 to assess the situation and share their expertise.

Officials say it's too early to blame any single cause, and a full technical review is now underway. 🔬📋

🔮 What's Next?

For now, crews will continue:

🪨 Filling underground cavities
🏢 Monitoring nearby buildings
🚇 Inspecting the tunnel
🔧 Preparing for permanent repairs

If everything goes according to plan, repairs should be completed within 7–12 days. 🗓️✨

📝 The Bottom Line

✅ The situation appears to be improving.

🚧 While repairs will take a little time, engineers are moving carefully to make sure the tunnel is fully stabilized before fixing the leak. It's a slower approach, but it's the safest way to protect nearby buildings, roads, and everyone in the area. 💜🚇
