Foam concrete bridge abutment backfill, the central tip: foam concrete data is used in road bridge abutment backfill. Foam concrete manufacturers are an innovative technology that changes the traditional abutment backfill technology. Foam concrete materials have the advantages of low density, light weight, high strength, integrated after filling, good impact resistance, no side pressure, and small foundation load.
At the back of the abutment or at the soft connection between the main bridge and the approach bridge or bridge head, after the foam concrete pavement is used, uneven settlement is liable to occur due to the overloading of the filler, the infiltration of rainwater and the failure of the bearing capacity of the foundation. The jump field is called bridge jump. 70% of the bridge repair cost is used to repair the bridgehead. The traditional method is to improve the bearing capacity of the foundation, which is not only difficult to solve the problem fundamentally, but also has problems such as long construction period and poor economy.

After the bridge abutment is backfilled with foamed concrete, it is in an over-consolidated state, which reduces settlement and uneven settlement, eliminates the post-construction settlement of the embankment itself, and avoids bumping at the bridge head. Since the reform and opening up, China's highway and bridge construction has developed rapidly.
In the construction of high-filled bridges, the abutment at the junction of roads and bridges, the soft connection between the main bridge and the approach bridge, etc., foam concrete manufacturers usually use low compression ratio soil (such as gravel soil or gravel residue) for filling. During the construction process, every 20-1250 px soil needs to be compacted, compacted, and compacted to meet the design requirements. The next layer is filled with soil, compacted, and compacted, and filled to the design level. The settlement time after construction is longer (several Months) to reach the design elevation.
In recent years, with the implementation of the new infrastructure construction plan, highway and bridge construction has entered a period of adjustment and development. China's highway and bridge construction has made brilliant achievements around the world. Our foam concrete machine also exported to many countries, if you are interested, pls feel free to contact us.
