Title:
CUT-OFF OF WATER FOR JOINT PART OF STEEL SHEET PILE, AND OUTFLOW PREVENTION HARDWARE
Document Type and Number:
Japanese Patent JP2014015809
Kind Code:
A
Abstract:

To provide cut-off of water for a joint part of a steel sheet pile, with which work can be performed easily by using low-priced materials and a water cut-off performance of a cutoff wall can be improved easily.

According to the cut-off of water for the joint part, a number of steel sheet piles 11 installed towards a water bottom surface are disposed successively and water within a cutoff wall 10 formed around a construction division 21 is pumped up. Thus, when the construction division 21 is used as a cutoff work space 22, ambient water is prevented from flowing from a joint part 12 of each of the neighboring steel sheet piles 11 into the cutoff work space 22. A clogging material is thrown into water outside of the cutoff wall 10 in a portion proximate with the joint part 12, and the thrown-in clogging material is pulled into a gap of the joint part 12 while riding on the flow of water flowing into the cutoff work space 22 via the gap of the joint part 12 in accordance with a water head difference between the cutoff work space 22 and an outside water surface. Thus, the gap is clogged by the clogging material, and the quantity of leaked water flowing into the cutoff work space 22 is suppressed.
