Title:
REVERSE LAYING AND INJECTION METHOD FOR CEMENT SUBSTANCE COMPOSITION
Document Type and Number:
Japanese Patent JPH0985727
Kind Code:
A
Abstract:
To favorably remove air between the ceiling surface of a concrete member and a molding box, and surely make a cement material composition stick to the ceiling surface.
Obstructive members (protuberances 21, 21...) which induce a turbulence state are arranged between the ceiling surface of a concrete member 1 and a form 7. Then, a cement material composition 10 is injected from one side at a speed of a degree which may cause a turbulence, and is discharged from the other side while entraining air, and is injected again after deaerating.
