Construction Engineering

New construction foundation treatmentFor newly constructed buildings on soft foundations (such as silt, clayey soil, silt loam, etc.), when the natural foundation bearing capacity fails to meet design requirements, compacting grouting can be used to strengthen the foundation. By grouting, the soil mass becomes compacted, enhancing the foundation's bearing capacity and reducing settlement and uneven settlement of the building. For instance, in the foundation treatment of some high-rise buildings, after applying compacting grouting reinforcement, the foundation bearing capacity can be significantly increased, satisfying the stability requirements of the structure.

Our company has successfully completed the foundation reinforcement of an existing building.In existing buildings, reinforcement of the foundation is often necessary due to reasons such as settlement, aging of the foundation, or structural renovations. Compaction grouting can effectively control further settlement of the foundation and enhance its load-bearing capacity. For instance, in old buildings with cracking walls caused by uneven foundation settlement, compaction grouting can reinforce the foundation, leading to stabilized settlement and repairing the wall cracks.

Municipal Engineering

Road and Bridge EngineeringDuring road construction, when encountering soft soil foundations or uneven ground settlement, compaction grouting can be used to reinforce the foundation, enhancing the stability and load-bearing capacity of the roadbed, and reducing road settlement and cracks. In bridge engineering, for the reinforcement of pier foundations, compaction grouting can increase the friction between the foundation and the soil, improving the pier's anti-overturning capability. For instance, in some city road renovation projects, compaction grouting was used to reinforce the sinking sections of the roadbed, achieving good results.

Subsurface Pipeline EngineeringDuring the construction and maintenance of underground pipelines (such as water supply and drainage pipelines, gas pipelines, cable pipelines, etc.), when the soil beneath the ground becomes loose, collapses, or there are voids around the pipelines, compaction grouting can be used for reinforcement. By filling the voids with grout, the compactness of the soil is improved, protecting the normal operation of the pipelines. For example, in the repair projects of underground drainage pipelines in some old urban areas, compaction grouting is used to reinforce the soil around the pipelines, preventing further sinking and damage to the pipelines.

Dam reinforcementDuring the long-term operation of dams, issues such as seepage and foundation settlement may arise. Compaction grouting can be used for the anti-seepage reinforcement of dams and foundation treatment. By injecting grout to fill the voids and cracks in the dam body and foundation, it enhances the dam's anti-seepage performance and stability. For instance, for some reservoir dams with potential seepage risks, the application of compaction grouting for anti-seepage treatment effectively prevents the occurrence of seepage.

Dike foundation treatmentThe stability of the foundation beneath a sluice gate directly impacts its normal operation. For soft ground or uneven settlement beneath the sluice gate foundation, compaction grouting can be an effective reinforcement method. By reinforcing the foundation through grouting, the bearing capacity and impermeability of the ground are enhanced, ensuring the safety and stability of the sluice gate.

Mining Engineering

Mining tunnel supportDuring the mining process, the stability of tunnels is crucial. When the soil or rock around the tunnel is fragmented and loose, compacting grouting can be used to reinforce the surrounding rock, enhancing its strength and stability to prevent tunnel collapses. For instance, in some coal mine tunnel support projects, compacting grouting was employed to reinforce the fragmented surrounding rock, ensuring the safe passage of the tunnel and the smooth progress of mining operations.

Airfilling TreatmentFor abandoned mining voids, to prevent ground collapse and ensure the safety of ground buildings, compacting grouting can be used to fill the voids. By injecting slurry, the voids in the mining voids are filled, the soil becomes compacted, and the stability of the ground is improved.

The dense grouting reinforcement method holds broad prospects for application in various engineering projects. By selecting appropriate grouting parameters and processes based on specific geological conditions and engineering requirements, excellent reinforcement effects can be achieved.
