What are the common causes of blockage faults in the end connection of the concrete conveying hose?

The common causes of blockage faults in the end connection of the concrete conveying hose are as follows: Concrete Sedimentation and Aggregation: During the transportation of concrete, if the conveying speed is too slow or the hose is left stationary for a long time, the concrete will settle and aggregate at the concrete hose ends.

The common causes of blockage faults in the end connection of the concrete conveying hose are as follows:
Concrete Sedimentation and Aggregation: During the transportation of concrete, if the conveying speed is too slow or the hose is left stationary for a long time, the concrete will settle and aggregate at the concrete hose ends. The coarse aggregates in the concrete may accumulate and block the end connection, especially in the case of low - slump concrete.

Improper Installation: If the end connection of the concrete hose is not installed correctly, such as incorrect connection angle or incomplete sealing, it may cause the concrete flow to be obstructed. For example, if the connection is not straight, the concrete will be prone to accumulate at the bend, leading to blockage.

Foreign Matter Entry: Foreign objects such as gravel, wood chips, or metal scraps may enter the concrete hose ends during the construction process. These foreign matters can block the passage of concrete, especially when they are large enough to get stuck in the end connection.

Hose Wear and Damage: Over - time, the concrete hose may wear out, especially at the ends where the concrete flow has a greater impact. Cracks, holes, or deformations in the hose ends can cause the concrete to leak or accumulate, which may eventually lead to blockage.

Inadequate Cleaning: After the concrete conveying work is completed, if the end connection of the concrete hose is not cleaned in a timely and thorough manner, the remaining concrete will harden and adhere to the inner wall of the hose and the connection, gradually reducing the cross - sectional area of the passage and causing blockage.
