Breakdown protection structure of underground construction against underground water pressure

摘要

The subject innovation relates to a fracture prevention structure of an underground structure by the water pressure, particularly for a single construction such as the sump or manhole or by the ground water pressure damage to the underground structure, underground due to that can be prevented from being subsidence pressure It relates to a fracture prevention structure of the structure.; Fracture prevention structure of an underground structure by the water pressure according to the present invention, the rubble layer 30 having a flow cavity of the ground water to the outer peripheral bottom of the underground construction 10 is laid a predetermined height, the plurality over the rubble layer 30 of yugonggwan (40) are ipseol, characterized by consisting of a gravel-filled the structure on the periphery of ipseol yugonggwan 40.; According to fracture prevention structure of an underground structure by the water pressure according to the present invention, by releasing the water pressure to the underground structure, such as the sump or manhole through yugonggwan, can easily prevent uplift of underground structures, cracks, breakage, etc. .
