New-type formwork empowers retaining wall construction, laying a green and efficient foundation for infrastructure development.

Retaining walls are critical structures in infrastructure projects such as slope protection, road support, and riverbank stabilization. The quality and stability of their construction directly affect the safety of the surrounding environment, the smooth flow of traffic, and the long-term operation and maintenance costs of the project. Against the backdrop of the construction industry’s accelerated push toward a green and low-carbon transformation, issues such as weak lateral resistance of formwork, low construction efficiency, and high resource consumption in traditional retaining wall construction have become increasingly prominent. The widespread adoption of Modular Cube rapid-installation formwork is bringing about comprehensive innovation in retaining wall construction and providing solid support for the high-quality development of infrastructure projects.

Traditional retaining wall construction typically relies on wooden and steel formwork, both of which have numerous limitations that are difficult to overcome. Wooden formwork lacks sufficient strength; at greater pouring heights, it tends to bulge and deform, making it challenging to ensure the wall’s verticality and smoothness. Moreover, its service life is limited to only 5 to 8 cycles. The massive consumption of timber not only drives up construction costs but also leads to severe resource waste and ecological damage. Although steel formwork offers some resistance to lateral pressure, its unit area weight can reach as high as 70 kg. During retaining wall construction, it requires frequent lifting and assembly using heavy cranes, which not only increases machinery rental costs and construction energy consumption but also prolongs the project schedule due to the complexity of assembly. Furthermore, traditional formwork places stringent demands on the technical proficiency of construction workers, keeping labor costs persistently high and making it difficult to meet the current need for efficient advancement in infrastructure projects.

The modular quick-assembly formwork developed by Mo Li Fang focuses precisely on addressing the core pain points in retaining wall construction, achieving all-round upgrades through material innovation and structural optimization. The high-polymer composite material it employs combines high strength with lightweight characteristics; its self-weight per unit area is only 20 kilograms, a 70% reduction compared to traditional steel formwork. As a result, large lifting equipment is no longer required at the retaining wall construction site, and construction workers can manually handle, assemble, and disassemble the formwork with ease. Meanwhile, the formwork adopts a standardized, modular design tailored specifically for retaining wall construction needs, featuring dedicated modules for straight sections, corner sections, and variable cross-sections. This allows for rapid, "building-block-style" assembly, boosting construction efficiency by more than double compared to conventional formwork. With just a short period of training, ordinary workers can become proficient in operating the system, significantly lowering the entry barrier and labor costs for construction projects.

In terms of the core quality requirements for retaining wall construction, this formwork demonstrates exceptional adaptability and reliability. The polymer composite material boasts outstanding structural stability and resistance to lateral pressure, with a lateral-pressure resistance strength reaching up to 25 kN/㎡. During continuous concrete pouring of 5-meter-high retaining walls, it remains highly resistant to deformation and mold expansion, enabling precise control over the geometric dimensions of the wall. This effectively eliminates common quality issues associated with traditional formwork, such as slurry leakage and honeycomb or rough surface defects, thus ensuring a smooth and uniform wall appearance. Moreover, with a reusability cycle exceeding 200 times, this formwork is perfectly suited to the large-scale construction demands of retaining wall projects. Even after repeated use, it continues to maintain stable performance, thereby reducing template wastage and minimizing the generation of construction waste right from the source.

The application of modular rapid-assembly formwork in retaining wall construction has achieved a dual enhancement—both economic benefits and environmental value. The full lifecycle cost is reduced by 30% to 50% compared to traditional formwork. Its lightweight design lowers machinery rental expenses, while efficient construction practices shorten project durations and reduce costs. This formwork system is ideally suited to meet the cost-control requirements of various retaining wall projects, including municipal slope stabilization, highway embankments, and river channel remediation. From an environmental perspective, constructing 100,000 square meters of retaining walls can save nearly 75 acres of forest land, reduce construction waste generation by more than 90%, and achieve a recycling rate of up to 85% for decommissioned formwork. This not only aligns with the policy direction of resource utilization of construction waste but also helps infrastructure projects attain their goals of green and low-carbon construction.

Currently, as the “15th Five-Year Plan” deepens its deployment of a green and low-carbon transformation in urban and rural construction, the demand for safe, stable, efficient, and environmentally friendly infrastructure construction—such as retaining walls—is becoming increasingly urgent. Thanks to its core advantages of strong lateral pressure resistance, reliable quality, and energy efficiency and environmental friendliness, Modular Cube prefabricated formwork is gradually emerging as the preferred solution for retaining wall construction. In the future, as technology continues to evolve and improve, this innovative formwork will be widely adopted in more large-scale slope stabilization projects, road infrastructure developments, and riverbank protection initiatives, thereby laying a solid and green foundation for “Made in China” infrastructure.
