SAND SUCTION AND OUTFLOW PREVENTING CONSTRUCTION METHOD FOR SEASHORE STRUCTURE FOUNDATION GROUND

摘要

PROBLEM TO BE SOLVED: To provide a sand suction and outflow preventing construction method for suppressing upward seepage flow in the foundation ground due to waves to effectively prevent suction and outflow of sand. SOLUTION: Inside the water bottom foundation ground 1 for constructing a seashore structural body 3 such as an embankment receiving wave external force, a water-impermeable layer 4 is arranged horizontally by embedding a water-impermeable sheet/mat type object or forming a water-impermeable solidified soil layer by injection of an agent.
