Title:
UNDERGROUND WALL AND CONSTRUCTION METHOD OF UNDERGROUND WALL
Document Type and Number:
Japanese Patent JP2014167228
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an underground wall and a construction method thereof, capable of efficiently forming a water communication part.SOLUTION: A core material 4, a cushioning material 5 and a tubular member 6 are installed in a body 11 of a soil mortar underground wall 1 before hardening its soil mortar. A crushing material 7 is arranged in the tubular member 6. A plurality of tubular members 6 are juxtaposed in a row along the thickness direction (t) of an underground wall body 11 between mutual adjacent two core materials 4 in a part for forming the water communication part 20 among the underground wall 1. The cushioning material 5 is arranged between the core material 4 and the tubular member 6 so as to sandwich a row of the tubular member 6 from both sides via the soil mortar in the horizontal extension direction (w) of the underground wall body 11. When crushed by the crushing material 7, a compression load P acts in a plane shape on a surface of the cushioning material 5, and the cushioning material 5 is compressed and deformed in the horizontal extension direction (w) of the underground wall body 11, and as a result of this, a crack C is formed in the thickness direction (t) of the underground wall body 11.
