Practical applications of the building sinking correction method using urethane foam pile.

为了使聚氨酯泡沫桩实际应用，有必要了解聚氨酯泡沫桩的承载力。当聚氨酯泡沫与两种药物溶液混合时，它会因压力而起泡并隆起地面。因此，为了确定承载能力，我们使用模拟聚氨酯泡沫桩的模型桩进行了加载模型试验。通过模拟聚氨酯泡沫桩的钻孔横向加载试验和聚氨酯泡沫注入试验，研究了发泡压力对地面上隆的影响范围。从而验证了聚氨酯泡沫桩的承载力和泡沫压力的传递范围。

In order to put urethane foam piles in practical use, it is necessary to understand the bearing capacity of the urethane foam piles. When urethane foam is mixed with two types of drug solution, it foams and uplifts the ground due to the pressure. Hence, in order to ascertain the bearing capacity, we performed loading model experiments using a model pile that simulates a urethane foam pile. We also investigated the range of the ground uplifting due to the foaming pressure based on the following methods: a lateral loading experiment in the borehole simulating a urethane foam pile, and a urethane foam injection experiment. As a result, we could verify the bearing capacity and the transmission range of the foam pressure of urethane foam piles.
