Injection Works
One of the most critical stages in soil and rock mechanics engineering is improving the properties of existing soil or rock mass and increasing its structural strength. In construction, dam, tunnel, bridge, and high-rise building projects, the soil's natural bearing capacity is often insufficient. Injection, which comes into play at this point, allows the pressure injection of special materials into the soil or rock to fill voids, increase impermeability, and enhance strength.
Rhino Engineering is a leading company in ground safety with its injection techniques implemented in accordance with international standards.
What is grouting?
Grouting is the process of injecting cement, chemicals, or other special mixtures into the ground or rock mass under a certain pressure. The aim is to fill voids in the ground, increase strength, or ensure water resistance.
Grouting techniques are frequently used in dam bodies, tunnel excavations, foundation excavations, metro projects, and ground improvement works.
The Importance of Grouting
In modern construction, grouting is not only a support but also a guarantee of safety. Because:
The risk of soil liquefaction is reduced,
Soils with low bearing capacity are improved,
Water leaks and seepage are prevented,
Stability is ensured in tunnels and dams,
Settlement problems in structures are prevented.
In Turkey, especially located in an earthquake zone, injection techniques are critical for structural safety.
Injection Types Applied by Rhino Engineering
1. Cement Injection
This is the most commonly used method.
A cement-water mixture is pressurized into the ground.
Voids are filled and the ground hardens.
2. Chemical Injection
This is used when cement is insufficient.
Special chemicals such as polyurethane, acrylate, and epoxy are applied.
It is particularly effective in stopping water leaks.
3. Jet Grouting
This is a high-pressure injection technique.
Columns are created in the ground to increase bearing capacity.
It is common in deep foundation and subway projects.
4. Curtain Grouting
This is particularly applicable in dams and water structures.
Impermeability curtains are created in the ground.
5. Consolidation Grouting
This is used to reduce the risk of settlement in weak soils.
Secure soil layers are created within the foundation of a structure.
Application Areas of Grouting
Rhino Engineering's grouting services play a critical role in many engineering projects:
Dams: Preventing water leaks and ensuring impermeability.
Tunnels: Preventing water ingress during excavation and ensuring roof stability.
Buildings: Foundation improvement in soils with low bearing capacity.
Metro projects: Resolving settlement and water problems in underground structures.
Bridges and viaducts: Securing footings.
Industrial facilities: Strengthening soils that will support heavy loads.
Rhino Engineering's grouting process
Soil investigation: The soil structure is analyzed through geotechnical investigations.
Design: Determining the most appropriate grouting method.
Application: The material is pumped into the ground using modern grout pumps.
Control and testing: Soil strength and impermeability are measured.
Reporting: The entire project is presented in a technical report.
The Importance of Grouting in Turkey
Due to Turkey's geological structure, loose, permeable, and weak soils are found in many regions. Grouting is particularly needed in metro projects, dams, and bridges undertaken in major cities.
For example:
In preventing water leaks in Istanbul metro lines,
In creating impermeable walls in the GAP dam projects,
In Izmir, grouting plays a vital role in building foundations to prevent soil liquefaction.
