END STRUCTURE OF PRECEDING ELEMENT, REBAR FRAME AND CONSTRUCTION METHOD OF CONTINUOUS UNDERGROUND WALL

Japanese Patent JP2015175179

A

PROBLEM TO BE SOLVED: To provide an end structure of a preceding element, a rebar frame and a construction method of a continuous underground wall in which a joint part between elements of the continuous underground wall with water-stopping properties and cross sectional power transmission performance can easily be formed.SOLUTION: An end structure of a preceding element includes: a partition plate 13 disposed at the boundary part between the preceding element and a succeeding element; an end surface cover 14 disposed at the side of the succeeding element from the partition plate 13; a spacer 15 interposed between the partition plate 13 and the end surface cover 14; a connecting member 16 penetrating through the partition plate 13; and a water stop 17 disposed in a preceding element side surface and a succeeding element side surface of partition plate 13, respectively. The end surface cover 14 and the spacer 15 comprise materials that can be cut by a ground excavator, and the end of the succeeding element side of the connecting member 16 is disposed in a space formed between the partition plate 13 and the end surface cover 14.
