Single-side formwork construction technology for basement exterior walls
Single-sided formwork construction technology for basement exterior walls utilizes the sidewalls of the foundation pit as the outer formwork for the basement exterior walls, reducing construction steps and completely eliminating the need for fertilizer troughs. This not only solves the formwork challenges inherent in the confined space of fertilizer troughs and eliminates safety risks associated with working in confined spaces, but also mitigates the costs and quality issues associated with subsequent backfill construction.
The core of single-sided formwork construction technology for basement exterior walls is the combination of "integrated waterproofing" and a single-sided formwork system. This allows the basement exterior wall waterproofing to be constructed simultaneously with the main structure, reducing costs and increasing efficiency.
Waterproofing membrane is applied to the pit sidewalls directly or after spraying and leveling with plain concrete.
The pit sidewalls serve as the external formwork, while the internal formwork utilizes a steel tripod and anchor bolt reinforced support system for stability and reliability.
The basement exterior walls are cast with impermeable concrete, which offers both waterproofing and self-compacting properties. After pouring, a water-film coating is applied for moisture retention, minimizing thermal cracking and enhancing waterproofing and anti-seepage performance.
Single-sided formwork construction technology for basement exterior walls allows for both exterior wall waterproofing and construction to be completed simultaneously. This technology is suitable for projects with limited site space, resulting in insufficient working surface between the exterior wall and the pit sidewalls. This eliminates the need for fertilizer troughs, ensuring safety and efficiency, helping to reduce project costs and increase efficiency.
