As the “backbone” of the construction industry, the quality of concrete construction directly determines the durability and safety of building structures. From the pouring of concrete for super-high-rise buildings to the laying of the base layer for rural roads, projects of all scales rely on specialized concrete equipment systems.
According to the “Global Concrete Equipment Market Report,” the global concrete machinery market size exceeded $ 32 billion in 2024, with intelligent and integrated equipment accounting for an annual growth rate of 12.5%.
This article will systematically analyze the five core types of concrete equipment essential to the construction industry and thoroughly explore the technical features and application scenarios of complementary construction tools, providing industry professionals with a comprehensive reference from equipment selection to construction management.
♦ Equipment Configuration and Technical Parameters
The concrete batching plant adopts a closed-loop design of “material feeding – mixing – discharge,” with its core components comprising aggregate batching machines, cement silos, forced-action mixers, and a control system. Taking the HZS180-type batching plant as an example, its theoretical production capacity reaches 180 cubic meters per hour, with material feeding accuracy controlled within ±2% (for cement, water, and admixtures) and ±3% (for sand and gravel aggregates).
The mixing main unit typically adopts a double horizontal shaft forced-action structure, achieving material shear mixing through the counter-rotation of spiral blades. The mixing time is only 60-90 seconds, representing a 40% efficiency improvement compared to self-falling mixers.
♦ Engineering Application Scenarios
High-rise building clusters: For example, in the concrete center project of EPDA, three HZS-type mixing plants are operated in parallel, achieving a daily concrete supply capacity exceeding 5,000 cubic meters, and with concrete boom pump trucks to enable continuous pouring of the core tube.
Infrastructure projects: The Hong Kong-Zhuhai-Macao Bridge island-tunnel project uses specialized mixing plants equipped with anti-salt fog corrosion systems to ensure the long-term durability of high-performance concrete.
Precast Component Plants: PC component production requires coordination between the mixing plant and temperature control systems, achieving precise strength control through the addition of retarders and steam curing.
♦ Key Selection Criteria
Installed Power: Must match the transformer capacity at the construction site to avoid voltage fluctuations affecting mixing accuracy.
Dust Collection System: Dust emissions from pulse-jet baghouse dust collectors should be ≤30 mg/m³, meeting environmental protection requirements.
Aggregate Bin Capacity: Configured at 1.5 times the peak daily usage during the project’s peak period to reduce frequent material loading downtime.
♦ Innovative Design of Equipment
The self-loading concrete mixer combines the functions of a loader and a mixer truck. Typical models are equipped with a 270° rotating hopper, capable of automatically performing sand and gravel loading (with a loading height of up to 3.8 meters), electronic weighing (with an accuracy of ±1%), and mixing and transportation.
Its mixing drum features a dual-spiral blade design, with forward rotation for mixing (speed 14-18 rpm) and reverse rotation for unloading (speed 6-8 rpm). It can transport materials over a maximum distance of 50 kilometers, making it ideal for remote construction sites without fixed mixing plants.
♦ Cost-benefit Analysis
Take rural road construction as an example. Traditional solutions require small mixing stations and transport tankers, while self-loading mixer trucks can save 50% in equipment costs.
Actual data from a renovation project shows that the EP5.5H self-loading mixer truck can complete 120 cubic meters of concrete mixing and transportation per day, which is 30% more efficient than traditional solutions and reduces fuel consumption by 25%.
♦ Operating Precautions
Calibrate the electronic scale before loading: Use standard weights for three-point calibration (0%, 50%, 100% of full scale).
Slope operation restrictions: Maximum climbing angle ≤25°, avoid tilting of the mixing drum to prevent material segregation.
Maintenance cycle: Replace hydraulic oil every 500 hours, and apply lithium-based grease to the mixing bearings daily.
♦ Mechanical Structure Analysis
The core technology of the boom pump truck lies in the coordinated control of the boom system and the pumping system. Taking the EPDAS HBC37 model as an example, its five-section RZ-type boom achieves a maximum vertical height of 40 meters, utilizing electro-hydraulic proportional control with motion accuracy of ±0.5°.
The pumping system is equipped with a double-cylinder piston pump, with a maximum theoretical pumping pressure of 14 MPa and a flow rate of 120 cubic meters per hour, capable of meeting the pumping requirements for high-strength concrete.
♦ Key Points of Construction Techniques
Pipe layout design: The ratio of horizontal pipe length to vertical pipe height should be ≤3:1, with no more than 5 bends to minimize pressure loss.
Emergency pipe blockage handling: When the pumping pressure exceeds 1.5 times the rated value, immediately reverse the pumping direction and use a “forward pump – reverse pump – forward pump” cycle to clear the pipeline.
Concrete performance requirements: Slump should be controlled between 180-220mm, spread angle ≥500mm, and sand content should be 38%-42%.
♦ Typical Engineering Cases
During construction in the Philippines, multiple 56-meter boom pump trucks were used in conjunction with relay pumping to achieve uninterrupted pouring of C60 concrete at a height of 632 meters.
The pump trucks are equipped with GPS positioning and remote fault diagnosis systems, which monitor parameters such as pumping pressure and oil temperature in real time through an IoT platform, reducing equipment failure rates to 0.3 times per thousand hours.
♦ Integrated Technology Breakthroughs
The concrete mixer pump adopts a compact “mix-then-pump” layout, such as the EPDAS DJBT50-10-85 model, with a mixing drum capacity of 2.5 cubic meters and a pumping pressure of 10 MPa, making it suitable for narrow sites. Its innovative features include:
Α. Hydraulic system coupling design: The mixing and pumping systems share a common power source, improving energy utilization by 15%.
