Cancel the fat trough! Can the exterior wall of the basement be constructed like this?

The unilateral formwork support construction technology of the basement outer wall is to directly use the side wall of the foundation pit as the outer formwork of the basement exterior wall, reduce the construction process, completely cancel the fertilizer groove, not only solve the problem of difficult formwork support in the narrow space of the fertilizer groove, eliminate the safety risk of limited space operation, and avoid the common problem of backfill construction cost and quality in the later stage.

Basement exterior wall unilateral formwork construction technology

The core of the single-sided formwork construction technology of the basement exterior wall is the combination of "waterproof integration + single-sided formwork support system" technology, so that the basement exterior wall waterproofing is constructed with the main structure at one time, and the technology has been successfully applied in many projects of various engineering bureaus of China State Construction Group, realizing cost reduction and efficiency increase.

Schematic diagram of one-sided formwork support for the exterior wall of the basement

After the side wall of the foundation pit is directly or flattened by plain concrete spraying, the waterproof membrane is pasted for construction:

The side wall of the foundation pit is used as the outer template

The outer side of the foundation pit side wall is used as the template, and the inner formwork is reinforced by a steel tripod and anchor bolts, which is stable and reliable:

Single-sided formwork

The exterior wall of the basement is poured impermeable grade P10 concrete, which has both self-waterproof and self-compacting properties, and must be watered and coated with film to moisturize and maintain after pouring, so as to reduce the occurrence of temperature cracks and enhance the waterproof and impermeable performance:

Concrete pouring and curing

The unilateral formwork construction technology of the outer wall of the basement, the waterproofing and construction of the exterior wall are completed at one time, which is suitable for the project where the working surface of the outer wall and the side wall of the foundation pit is insufficient due to the narrow site, cancels the fertilizer groove, is safe and efficient, and helps the project to reduce costs and increase efficiency.
