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

#CMT# #/CMT# 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. #CMT#USE : #/CMT# Method for manufacturing structural element for swimming pool. #CMT#ADVANTAGE : #/CMT# The formation of air bubbles are greatly reduced by the de-aerated opening arranged at the upper panel. A structural element with small wall thickness is manufactured from high-strength concrete. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the formwork. 1 : Formwork 4 : Upper panel 5 : Pouring opening 6 : De-aerated opening 9 : Grooves.
