Examine if any cracks found on the abutments and the river embankment is in good condition |
If there are small cracks found on the abutments, use cement mortar to fill the crack to prevent erosion of the reinforcing bars inside the abutments. If there is damaged of the embankment, application of a mixture of cement mortar with scribbles to fill the cracks |
Once per month |
| Any reshape or damage of the support |
Replace the support if it is seriously damaged. (suggest Implementing by professional) |

Upon years of discussion and collaboration, PB100 Modular footbridge has applied the advantages of Bailey bridge and optimal choice of material in its projects. Great Wall Steam have been entrusted to develop and design a light-weighted PB100 Modular footbridge. The bridge design has been given due considerations to the demand of function, natural environmental condition, technical feasibility, material transportation and cost etc. As the requirement on loading was smaller, the structural members of the bailey panel could be re-designed to a lighter weight, meeting its needs on economic, transportation, construction and other means. With the premise of ensuring safety, PB100 Modular footbridge excels the conventional Bailey bridge limitations as mentioned and it has its unique advantage of application in the PB100 Modular footbridge projects.
