Project Overview
The MRT Jalan Gurney Escape Shaft 2 is part of the larger MRT Putrajaya Line (SSP Line) project in Kuala Lumpur, Malaysia. The escape shaft is a critical safety feature, designed to provide an emergency exit and ventilation for the underground sections of the MRT line. Located in a densely populated urban area, the construction of the escape shaft posed several engineering challenges, necessitating innovative construction techniques and stringent safety measures.

Theoretical Challenges and Solutions
1. Reinforced Concrete Shaft Construction:
- Challenges:
- Managing the depth and stability of the excavation in a densely populated urban area.
- Ensuring the structural integrity of the shaft during and after construction.
- Solutions:
- Utilizing advanced excavation techniques such as diaphragm walls and slurry walls to maintain soil stability and prevent collapse.
- Employing high-strength concrete mixes and reinforcement bars to achieve the required structural strength.
- Continuous monitoring of soil conditions and structural integrity throughout the construction process.
2. Waterproofing Works:
- Challenges:
- Ensuring complete waterproofing in an underground environment with high hydrostatic pressure.
- Preventing long-term water ingress that could compromise the structural integrity of the shaft.
- Solutions:
- Implementing a multi-layered waterproofing system, including membranes and sealants specifically designed for high-moisture conditions.
- Regular inspections and maintenance to detect and address any potential leaks or weaknesses in the waterproofing system.
- Use of high-quality waterproofing materials and advanced application techniques to ensure a robust and durable solution.
