Method for manufacturing structural element for swimming pool, involves de-aerating formwork through de-aerated opening arranged at upper panel such that openings are permeable to air but non-permeable to water

摘要

The method involves forming a concrete with strength greater than or equal to high-strength concrete and carrying the concrete into a formwork (1) through a pouring channel. A de-aerated opening (6) is arranged at an upper panel (4) of a formwork (1). The form work is de-aerated through the opening such that openings are permeable to air but non-permeable to water.
