Abstract

PURPOSE: To prevent a ground swell by providing a decompression hole penetrating a non-percolation layer immediately below an excavation bottom to a pressed aquifer, and discharging the spouting pressed water through the decompression hole.
CONSTITUTION: A decompression hole 5 penetrating a non-percolation layer 1 immediately below an excavation bottom 4 to a pressed aquifer 2 is provided. A well 6 is installed to the limit of the depth of the excavation bottom 4, and the pressed water spouting to the excavation bottom 4 is discharged through the decompression hole 5.
