Background

In modern construction projects, concrete pumping technology has become a key approach to enhancing construction efficiency and ensuring project quality. However, in actual construction, concrete pumping still encounters numerous challenges, such as pipe blockage and concrete segregation. These issues not only affect the construction schedule but may also increase costs and reduce structural strength.

In response to these two core challenges, Unique Group offers efficient, stable and low-failure-rate pumping solutions with advanced pumping technology and scientific concrete mix design, helping engineering teams achieve high-quality and high-efficiency concrete construction. 

1. Two Core Challenges in Concrete Pumping

1.1 Pipe Blockage: A Key Bottleneck Affecting Construction Efficiency

1.1.1 Analysis of Pipe Blockage Causes

During concrete pumping, pipe blockage is one of the most common malfunctions, primarily caused by the following factors:

(1) Improper concrete mix ratio: Slump that is either too high or too low, resulting in poor fluidity or segregation.

(2) Excessive aggregate particle size: Oversized coarse aggregates (e.g., crushed stone) becoming stuck at pipe bends or diameter transition points.

(3) Unreasonable pipeline layout: Excessive bends, overly long pump pipes, or inadequate lubrication, increasing pumping resistance.

(4) Insufficient pumping pressure: Inadequate equipment power or hydraulic system failure, leading to unstable conveying power.

1.1.2 Hazards of Pipeline Blockage

(1) Project delays: Blockage clearance requires work stoppage, significantly impacting construction progress.

(2) Increased costs: Manual cleaning, equipment wear, and concrete waste all lead to additional expenses.

(3) Compromised concrete quality: Re-pumped concrete after blockage may exhibit stratification or reduced strength.

1.1.3 Our Solution

Unique's integrated concrete mixing and conveying machine employs an intelligent pumping system combined with high-wear-resistant pipelines and dynamic pressure regulation technology to effectively reduce blockage risks:

Intelligent mix monitoring: Real-time slump detection with automatic pumping parameter adjustment

High-pressure pumping technology: High-capacity hydraulic pump ensures stable long-distance and high-drop conveying

Optimized pipeline design: Reduced elbow joints with ultra-high-molecular-weight polyethylene (UHMWPE) pipes featuring smooth interiors to minimize friction 

1.2 Concrete Segregation: The Invisible Threat to Structural Strength

1.2.1 Causes of Segregation

Concrete segregation refers to the separation of mixture components (cement paste, aggregates), leading to uneven distribution. Primary causes include:

(1) Excessive transport distance: Gravity-induced stratification of cement paste and aggregates during pumping

(2) Improper vibration: Over-vibration causes coarse aggregate settlement and cement paste floating

(3) Improper admixture use: Excessive retarders or water reducers affecting concrete stability

1.2.2 Hazards of Segregation

(1) Reduced strength: Non-uniform hardening decreases compressive strength

(2) Increased cracking risk: Uneven aggregate distribution leads to shrinkage cracks

(3) Impaired durability: Segregated areas become water-permeable, accelerating steel corrosion

1.2.3 Our Solution

Unique ensures concrete uniformity through intelligent monitoring + smart pumping control:

(1) Stabilizer technology: High-performance plasticizers prevent segregation during long-distance pumping

(2) Adaptive pumping system: Automatically adjusts pumping speed based on concrete state to minimize vibration effects

(3) On-site quality monitoring: Equipped with slump testers and flow measurement devices for real-time mix optimization
