What is the main purpose of a bulkhead in concrete framework?

The main purpose of a bulkhead in concrete framework is to contain the concrete within a specific section of the form. Bulkheads act as vertical barriers that help define where the concrete will be placed, forming distinct sections within a larger formwork system. This containment is crucial for ensuring that the concrete is poured accurately and maintains the desired thickness and shape, preventing it from spilling or flowing into adjacent areas that are not meant to be filled at that time.

Understanding this function highlights the importance of precise formwork in concrete construction. By properly containing the concrete, bulkheads contribute to the integrity and structure of the finished product, making them a fundamental element in the construction process. Other options—while potentially relevant to different aspects of concrete work—do not address the primary role of bulkheads as effectively as this one does.
