Treatment measures for concrete cracks

Concrete crack​ is a common phenomenon in concrete structure. Its appearance will not only reduce the anti seepage ability of the building, affect the use function of the building, but also cause corrosion of steel bar, carbonization of concrete, reduce the durability of the material and influence the bearing capacity of the building, so it is necessary to enter the concrete crack.

Load-bearing strengthening in the machine room

Now load-bearing strengthening method can be divided into: steel plate strengthening, FRP strengthening, the structural strengthening, the dismantling and strengthening of the load-bearing wall, and post installed anchor.

Strengthening and Repair the Crack of Bridge

There are several structural strengthening system to deal with the cracks which have great damage to the structure, such as the steel plate bonding reinforcement, the carbon fiber fabric bonding reinforcement, the reinforcement of the beam body section size and the prestress FRP plate reinforcement method

Bridge structural strengthening technology

There are mainly 5 structural strengthening technology to strengthening bridges. 1) strengthening the weak components; 2) add auxiliary components; 3) change the structure system; 4) reducing the constant load; 5) reinforcement of pier and abutment and foundation.

Increasing Storey on Existing Buildings

Whether the existing building meets the conditions for the upgrading of the floor, it should be identified by the age of construction, the degree of damage, the structure, the importance of the building and the requirements of the use.

Cause Analysis of Culvert Defects and Reinforcement Treatment

In the construction of highway engineering, in order to make the road smoothly pass through the canal without obstructing the traffic, the drainage channel (through the passage) under the roadbed is built under the subgrade. Through this structure, the water can flow through the underside of the road.

Technology of bridge strengthening and retrofitting

Bridge strengthening is generally to restore or improve the bearing capacity of existing bridges by improving the strength of the components and improving the structural performance, so as to prolong the service life of the bridge and adapt to the requirements of modern transportation.
