AI Technical Summary
Technical Problem
The existing manhole covers and their bases have low tensile and crack resistance, making them prone to deformation and damage, which affects safety during use.
Method used
A reinforced manhole design is proposed, employing a mesh structure composed of concrete pad rings, strip bars, inner ring bars, outer ring bars, and longitudinal bars. Combined with the supporting structure, this forms a multi-layered ring reinforcement design and a transverse truss structure, dispersing external stress and enhancing structural stability.
Benefits of technology
It significantly improves the pressure and impact resistance of manholes, avoids local stress concentration, enhances stability and service life, prevents collapse, and strengthens safety in use.
