What Should Be Paid Attention To When Pouring Concrete With Concrete Pump

Nowadays, concrete is a widely used building material in construction. Pouring and tamping concrete are crucial aspects of the process and require strict attention to detail. Therefore, it is important to acknowledge what must be taken into consideration during concrete pouring. This is a concern shared by many in the construction industry.

In order to ensure smooth progress during construction, certain operations should be carried out on the concrete pump truck before pouring the concrete. When it comes to pouring and pounding the concrete, there are several aspects that need to be taken into consideration. These include:

1. Preparation: Prior to pouring the concrete, it is essential to adequately prepare the area. This involves removing any debris or materials that may hinder the pouring process. Additionally, ensuring that the formwork is set up correctly and securely is crucial for maintaining the desired shape and structure of the concrete.

2. Consistency of the concrete: The consistency of the concrete must be carefully monitored and controlled. It should have the appropriate water-cement ratio to ensure it is neither too fluid nor too dry. This enables the concrete to flow smoothly through the pump truck and aids in achieving the desired density and strength.

3. Communication with the pump operator: Effective communication with the pump operator is essential during the pouring process. It is important to provide specific instructions regarding the placement and movement of the concrete. This can help prevent any potential issues such as blockages or uneven pouring.

4. Continuous pouring: Once the concrete pouring starts, it should be carried out continuously until the desired area is covered. Gaps or interruptions in the pouring process can lead to weak spots or disintegration of the concrete. Therefore, it is crucial to have the necessary resources and manpower to ensure a seamless and uninterrupted flow of the concrete.

5. Monitoring and quality control: Throughout the pouring process, it is important to monitor the concrete's consistency, temperature, and curing time. This is done to identify any deviations or issues that may affect the quality of the final structure. Regular inspections, such as slump tests and temperature measurements, can help ensure the concrete meets the required specifications and standards.

By considering these aspects and following proper procedures, the pouring and pounding of concrete can be executed successfully. This ensures that the construction progresses smoothly and the finished structure meets the desired quality and durability standards.

1. Wet hollow cylinder

In order to ensure the quality of the structural concrete, the construction workers take measures to minimize the negative impact of the hollow cylinder's continuous water absorption. Before pouring the concrete pump, they dampen the cylinder by pouring a specific amount of water onto it, which helps to reduce its water absorption. This step is crucial to maintaining the integrity of the concrete structure.

2. Pouring and vibrating

To ensure the quality of the construction process, it is crucial that the steel protection layer and floor elevation are closely monitored by the construction team. Additionally, the pouring and vibrating of the concrete must be carried out with utmost care to prevent defects such as pockmarked surfaces or honeycombing from appearing in the finished floors. By following these guidelines, the construction project can proceed smoothly and ensure that the final result meets all necessary standards for quality and safety.

3. Bamboo plywood

To ensure the safety of the CBM inner membrane during construction, it is necessary to follow some guidelines. One of them is placing the support of the concrete pump on the bamboo plywood, and the operator must also work on it. However, it is strictly prohibited to step directly on the CBM inner membrane to avoid causing any damage to it. Therefore, all workers should be aware of this precautionary measure and take necessary steps to ensure that the CBM inner membrane remains intact. With this in mind, we can ensure that the work is completed smoothly and without any issues.

4. Outlet

To protect the inner mold from direct impact, a 45-degree elbow is installed at the discharge port, effectively diverting the flow of concrete away from it.
