発生する浮力を最小限に阻止する。(Operation) According to the present invention, when the civil embankment block is laid on soft ground or ground slope slope to construct a civil engineering structure, the structure is affected by groundwater due to subsidence of the ground. In this case, water that has penetrated into the honeycomb structure through the water-permeable hard plate adhered to the outer peripheral surface of the plastic honeycomb structure that constitutes the main body of the block is a communication hole provided in the partition wall of the structure. The buoyancy generated in the block due to submersion in water is prevented to a minimum by entering into the cavity of the honeycomb structure defined by the partition wall through.
