<P>PROBLEM TO BE SOLVED: To provide a dam and dam construction method, capable of eliminating components which interfere with casting and compacting operations of hardening material (internal material) so as to reduce number of components and simplify operations. <P>SOLUTION: An upstream wall surface material 100 constituting a dam 1000 has a lowermost half LP (liner plate) 30 arranged on a through component 20 on the bottom installed on an upstream base concrete 10, a lowermost full LP50 which is connected to the half LP30, and a supporting full LP60 formed of a corrugated steel plate 61 having an upstream surface to which a supporting connection plate 64 is fixed. In a state that the supporting full LP60 having the supporting connection plate 64 to which an upper end of the supporting column 80 is connected is tilted toward downstream direction at a predetermined angle, a lower end of the upper end of the supporting column 80 is fixed to the upstream base concrete 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
