She actually stepped on a bucket to work in a deep well to remove broken piles! It was so thrilling!

Описание: ✅ What is a broken pile?
🧱 A broken pile refers to an undesigned fracture or suspension of the pile body during the construction of the cast-in-place pile, which is commonly seen in:
Concrete segregation and insufficient slump during pouring;
Uneven geology or collapsed holes;
The steel cage is stuck and the sinking is blocked;
The vibration of the pile driver is stopped or jumps.

✅ Hazards of broken piles:
⚠️ It will lead to insufficient bearing capacity and uneven foundation settlement, which will seriously affect the safety of the building structure.

✅ Common methods for handling broken piles:
🔨 1. **Manual breaking method**:
Break the top broken pile section and reconnect the pile;
Suitable for situations where the broken pile depth is shallow and the position is controllable.

🚧 2. **Pile sleeve method**:
Drill another circle of large-diameter piles outside the original pile to expand the bearing surface;
Commonly used in scenarios where the pile head is offset or the original pile is no longer available.

🚀 3. *Explosive method* (rare):
Use explosives to break hard pile heads or foreign objects, which is high-risk and difficult to control.

✅ Safety knowledge for deep well operations:
🕳️ Deep wells usually refer to working spaces deeper than 2 meters, which are limited space construction.
🔒 The following specifications must be met:
⛑️ Wear a safety helmet, non-slip shoes, and a full-body safety belt;
⛓️ Use a cage or lifting platform to go up and down, and do not step on temporary items such as buckets and scaffolding;
💨 Set up forced ventilation and regularly detect toxic gases;
👥 Arrange a dedicated person to monitor the well and maintain communication.
