In some highway projects, some small streams or small channels will pass through, and a small bridge hole, also called a culvert, will be repaired. In this kind of structure, cracks or concrete peeling often occur in actual use because the vehicle has a large weight and the bridges have been eroded by water all the year round. Then we will tell you how to use the carbon fiber cloth and building planting bar adhesive to reinforce the bridge.
The reinforcement of the bridge holes can basically be used to reinforce the bridge. However, after the actual investigation, we usually choose a lower cost method to strengthen the concrete, depending on the degree of disease. Usually there are small cracks or partial concrete peeling. We can take the way to repair the crack and then match the carbon fiber cloth.
1. Repairing the cracks;
It is recommended to use the filling glue. Mankate filling glue can be injected into 0.1mm micro crack. It has low viscosity and strong penetration, mainly anti-humid heat aging, providing assistance for the harsh outdoor environment reinforcement.
2. Carbon fiber cloth reinforcement;
After repairing the cracks, the carbon fiber cloth is reinforced. Mankate carbon fiber cloth has acid and alkali resistance, corrosion resistance, and can be bent and wound. It is suitable for all kinds of curved surfaces and special-shaped members. The tensile strength can be up to 8 times steel, and it is easy to post and also affordable.
However, if a large area of concrete falls out in the culvert, causing corrosion of the steel bars, then the planting bar adhesive reinforcement is required in this case. If the reinforcement is used, the building reinforcement glue is used.
Nanjing Mankate building planting bar adhesive is resistant to acid and alkali, high and low temperature resistance, aging resistance, and can maintain long-term load stability in humid environment. It is a good choice for general bridge and culvert reinforcement, but this method is suitable for large-area damage, and higher cost.
The specific reinforcement method to be used depends on the actual conditions of the project. The carbon fiber cloth reinforcement and the construction planting bar adhesive reinforcement both have advantages and disadvantages. It is recommended to consult professionals before strengthening.
