BURIED FORM UNIT AND CONSTRUCTING METHOD OF DAM EMBANKMENT BODY

摘要

PURPOSE: To impart landscape beauty to a dam embankment body, and to save the labor of operation and improve safety by installing a frame body for bearing on the rear side of buried forms by using a connecting jig and placing the lower end face of the frame body for bearing at a position lower than the lower end of the buried forms. ;CONSTITUTION: The surface side of buried forms 1 is formed in appearance having excellent landscape properties harmonizing with natural environment. Channel steel 3 is assembled on the rear side of the buried forms 1 at a regular interval at two upper and lower stages by using connecting Jigs. Frames 6 made of steel are mounted on the buried forms 1 through the channel steel 3, thus constituting a buried form unit A. The vertical height size of the buried forms 1 and the frames 6 made of steel is equalized approximately, and the frames 6 made of steel are displaced downwards and installed at double levels so that connecting surfaces at the lower ends of the frames 6 made of steel are placed at positions lower than the lower end of the buried forms 1. Accordingly, the frames 6 made of steel of the unit A placed at the upper stage of the unit A are consolidated by placing concrete up to the upper end of the unit A, and brought to the state, in which the frames 6 are fixed firmly.;COPYRIGHT: (C)1996,JPO
