PROBLEM TO BE SOLVED: To facilitate the construction and repair of a structure, by adjusting the level by the combination of a proximity means closely bringing the upper member and the lower member and a separation means bringing them apart and forming a space between them and charging cement mortar therein, in a method in which a conditioning material is charged in a space between upper and lower members constituting an underground structure.
SOLUTION: After a lower frame 14 has been superposed on a base part to roughly adjust the height in order to install a frame body 12 up to an objective height 32 like a road face for a building, the height of the frame body 12 is adjusted by use of an adjusting ring 15 or an adjusting material. The frame body 12 is supported on the adjusting ring 15 by supporting members 17 like bolts and cement mortar is charged in the space 18. The proximity means A is the bolt-form support members 17. The lower ends are embedded in the lower frame 14 and the upper ends are projected to the flange 12a of the frame body 12. The frame body is pulled by the fastening tools 12b like nuts. As a separating means B, an adjuster 20 constituted of screw members 21, 22 of bolts and nuts is used.
【目的】 地下構造物における高さ調整を容易化し、か つ損傷時には簡単に補修できるようにする。
【構成】 下位部材例えば調整リング１５と、上位部材 例えば枠体１２とを引き寄せる接近手段Ａと、押し離す 離間手段Ｂとを組み合わせて、上位部材を目的の高さに 調整する。この調整によって上位、下位両部材の間に空 間１８を形成し、かつ必要な型枠２５ａ…で囲み、その 中にセメントモルタル等を充填する。
