Preparation method of polyurethane cured calcareous sand triaxial sample
The invention discloses a preparation method of a polyurethane cured calcareous sand triaxial sample, which can realize convenient preparation of the polyurethane cured calcareous sand triaxial sample, and comprises the following steps: screening and elutriating calcareous sand particles; the treated calcareous sand particles are dried; mixing and stirring the dried calcareous sand and the polyurethane white liquid; mixing and stirring the mixture of the calcareous sand and the polyurethane white liquid with the polyurethane black liquid; and performing layered compaction and sample preparation, and performing sample maintenance. The method is convenient to operate and simple in process, the mechanical behavior of the calcareous sand can be effectively improved, a new technology and a new thought are provided for the calcareous sand foundation treatment problem in island engineering, and the method has high practical engineering application value.
本发明公开了一种聚氨酯固化钙质砂三轴试样制备方法,可以实现聚氨酯固化钙质砂三轴试样的便捷制备,包括以下步骤:对钙质砂颗粒进行筛选及淘洗处理;将处理后钙质砂颗粒烘干;将烘干后钙质砂与聚氨酯白液混合搅拌;将钙质砂与聚氨酯白液混合物与聚氨酯黑液混合搅拌;进行分层击实制样并进行试样养护。本发明方法操作便捷,工艺简单,可有效地改善钙质砂力学行为,为岛礁工程中钙质砂地基处理问题提供一种新技术和新思路,具有较高的实际工程应用价值。
