Document Type and Number:
WIPO Patent Application WO/2022/195996
Kind Code:
A1
Abstract:
[Problem] To improve the handleability of a civil engineering work bag body by eliminating catching of a knitted fabric constituting the civil engineering work bag body, to facilitate the work of positioning a civil engineering work bag body with respect to a molding box device, and to improve efficiency of manufacturing a structure for civil engineering work. [Solution] A molding box body of a molding box device 10 for infill material formation is imparted with a reverse taper shape with an open upper opening, one or a plurality of overhanging handles 17 are provided on the outer circumferential surface of the molding box body, and the overhang handles are made to have a dimensional relation of being larger than the dimensions of the mesh of a knitted fabric constituting a civil engineering work bag body such that the civil engineering work bag body does not hook onto the overhang handles.
