EPS Underground Pipe Protection Method

basic information

This construction method involves encasing underground installations (such as pipes and utility tunnels) in a structure made of expanded polystyrene, which improves workability, reduces costs, and prevents sinking due to liquefaction. Even if differential settlement occurs due to liquefaction, it is possible to maintain the ground surface prior to the earthquake, thereby preventing damage to the buried installations. (Principle) Even when the buried pipes and the expanded polystyrene structure are combined, their overall density is lighter than that of liquefied mud, causing them to attempt to float on the liquid soil. However, the weight of the asphalt or concrete on the surface prevents excessive buoyancy, allowing the structure to maintain its condition.
