Tunnel Methodology
Advantages of Tunnel System
Foundation and Precision Setup
Ground slabs laid to detailed specifications.
Kicker placement guides precise tunnel form installation.
Wall reinforcements set with exactness.
Concrete Pouring and Insulation
Reinforcement for slabs installed, with preparations for subsequent levels.
Comprehensive checks ensure readiness for concrete pouring
Insulation measures applied for concrete setting in varied climates.
Formwork Placement and Assembly
First Half-Tunnel set is placed by crane, aligned with precision.
Window/door openings and electrical conduits integrated seamlessly
Second Half-Tunnel unit placed, ensuring perfect vertical alignment.
Systematic Dismantling and Progression
Post-concrete heating facilitates curing, with dismantling commencing the next day.
Tunnel units cleaned, oiled, and moved for the next cycle
Continual progression with reinforcement in place for the next phase.
Formwork Securing and Site Preparation
All tunnel form units are methodically aligned for concrete pouring.
Tie-rods secured, horizontal surfaces prepared for concrete.
Essential components for slabs and walls are meticulously positioned.
Finishing and Cycle Repetition
Surfaces treated post-stripping for quality preservation.
Back propping supports the structure as the cycle repeats.
Efficient transition to the next level with strategic formwork management.
Improved safety:
The tunnel form work system can improve safety on the construction site . This is because the form work is enclosed , which helps to protect workers from falling objects and other hazards. as it reduces the need for workers to work at heights.
Efficient Use of Materials:
The tunnel form work system can help to improve the efficiency of material usage . This is because the form work is reusable , which reduces the amount of waste that is produced .
High-Quality Finishes:
The tunnel form work system produces high - quality concrete finishes that require minimal finishing . This is because the form work is made from smooth materials that do not absorb moisture , which helps to prevent the formation of cracks.
Reduced Laborcosts:
The tunnel form work system requires less labor than conventional methods. This is because the form work is prefabricated and can be easily assembled and disassembled by a small team o f workers.
Fast Construction Speeds:
The tunnel form work system can significantly reduce construction times compared to conventional methods. This is because the walls and slabs are cast in one operation , which eliminates the need for time - consuming form work stripping and re-setting .
Accuracy:
The system is very accurate, which reduces the need for rework.
