Building Columns with IMER Small 50 Concrete Pump

Grouting a column using an IMER Small 50 is an excellent choice for small to medium-sized grouting projects. The IMER Small 50 is a versatile, compact, and reliable grout pump designed for ease of use, especially for tasks like grouting structural elements such as columns. It ensures a consistent and smooth grout application, which is crucial for filling voids and providing support to structural columns.

To build columns with the grouting machine SMALL 50 at the underground project location, with the following specifications:

- Columns Height: 95cm

- Columns Width: 40cm

Here's a step-by-step guide to grouting a column with an IMER Small 50:

Steps for Grouting a Column with an IMER Small 50

1. Preparation of Materials and Equipment:

• Prepare the Grout: Select the appropriate grout mix based on the application (e.g., cement-based, epoxy, or non-shrink grout). Follow the manufacturer's instructions for mixing the grout to achieve the right consistency. The grout should be smooth and free of lumps.

• Prepare the IMER Small 50: Ensure the grout pump is clean and in good working condition. Check for any blockages or wear on the pump components (such as hoses, nozzles, and gaskets).

• Connect the Hoses: Attach the suction hose to the grout container and the discharge hose to the nozzle or the placement area. Ensure that the hoses are securely connected and that there are no leaks.

• Mix the Grout: Mix the grout thoroughly using a drill with a mixing paddle or a mechanical mixer, depending on the grout volume. Ensure that the grout is homogeneous and free from air pockets.

2. Set Up the IMER Small 50 Pump:

• Position the Pump: Place the IMER Small 50 grout pump close to the column for easy grout transfer. Ideally, the pump should be positioned at a height that allows gravity to help move the grout into the column, reducing strain on the pump.

• Prime the Pump: Before starting the grouting process, prime the pump to ensure the grout flows smoothly. You can do this by running the pump without pressure to expel air from the system. Once grout starts to flow through the hoses, the pump is primed and ready for use.

3. Grout Injection Process:

• Start Pumping: Turn on the pump and start injecting grout into the column. Begin at the bottom of the column and work your way upward to ensure proper filling and to prevent air pockets. Grouting from the bottom allows the grout to rise and fill the column evenly.

• Apply Steady Pressure: Keep a steady flow of grout by maintaining consistent pressure on the pump. Avoid over-pumping or forcing the grout into the column, as this can lead to air entrapment or uneven filling.

• Monitor the Grout Flow: Keep an eye on the grout as it enters the column. If the grout begins to overflow, stop pumping momentarily to allow the grout to settle. You may need to adjust the pump speed to ensure a controlled and consistent flow.

• Check for Voids: Watch for any voids or areas where the grout isn't filling properly. If necessary, pause and reposition the pump or hoses to target areas that require additional grout.

4. Ensure Full Column Saturation:

• Fill Completely: Ensure that the column is filled completely by checking the grout flow and monitoring the level. Continue to pump grout until there are no visible gaps or air pockets. If necessary, use a vibrating tool or tap the column gently to help the grout settle and eliminate trapped air.

• Check for Leaks: Inspect the column for any leaks during the grouting process. If grout is seeping out from unexpected areas, stop the pumping and address the issue before proceeding.

5. Finish the Grouting:

• Stop Pumping: Once the column is fully grouted, turn off the IMER Small 50 pump. Ensure that all hoses and connections are free from grout residue to prevent blockages.

• Smooth the Surface: If the column has any exposed grout or surface imperfections, use a trowel or smoothing tool to finish the surface. Ensure a smooth and even finish to prevent uneven curing.

6. Curing the Grout:

• Allow Curing: Let the grout cure as per the manufacturer’s instructions. Depending on the type of grout used, this could take anywhere from a few hours to several days. During this time, avoid disturbing the column and ensure the area is kept moist if required for curing.

• Protect the Column: If the grouted column will be exposed to elements or high temperatures, cover it with plastic sheeting or wet burlap to maintain humidity and prevent cracking.
  

Additional Tips:

• Maintain Proper Water-to-Cement Ratio: When mixing grout, ensure that you’re using the correct water-to-cement ratio. Too much water can weaken the grout, while too little can result in a thick and difficult-to-pump mixture.

• Consistency of Grout: The grout should have a smooth, pourable consistency. If it’s too thick, it may clog the pump or cause difficulty in filling the column. If it’s too thin, it may not provide adequate support or strength.

• Check Pump Function: If the grout stops flowing, check for blockages in the hoses, pump, or nozzle. Use a soft brush to clear any minor obstructions.
  

Cleaning the IMER Small 50:

• After grouting, clean the pump and hoses thoroughly to prevent grout from hardening inside the machine and hoses. Use water or a suitable cleaning agent to flush out any leftover grout. Be sure to follow the manufacturer’s recommended cleaning procedure for your specific model.
  

Benefits of Using IMER Small 50 for Grouting Columns:

• Ease of Use: The IMER Small 50 is compact and user-friendly, making it ideal for small to medium-sized grouting tasks.

• Consistency: It provides a steady, controlled flow of grout, ensuring even and consistent filling of the column.

• Efficiency: The IMER Small 50 can handle both small and large volumes of grout, making it an efficient choice for grouting applications.
