    • A method of repairing a utility pole in place. The method comprises excavating soil from around the utility pole to expose a portion of the pole surface below the ground line, and adhering a plurality of prefabricated sleeve segments to the surface of the utility pole to form a circumferential sleeve. The plurality of sleeve segments are positioned to extend above and below the ground line and have side edges that each overlap an edge of an adjacent sleeve segment. The hole around the pole is then filled, such as with a slurry of soil, water and sodium silicate. This method may be beneficially used on wooden utility poles that have experienced decay, in order to restore strength to the pole.
    • 修理电线杆的方法。 该方法包括从电线杆周围挖掘土壤,露出地面以下的极面的一部分,并将多个预制的套筒段粘结到电线杆的表面,形成圆周套筒。 多个套筒段被定位成在接地线的上方和下方延伸并且具有侧边缘,其各自与相邻套筒段的边缘重叠。 然后填充杆周围的孔,例如用土壤,水和硅酸钠的浆料。 这种方法可以有益地用于经历衰减的木制电线杆上,以便恢复极点的强度。

    • An improvement in the known method of setting or resetting poles in the ground with foamed polyurethane resins formed in-situ from polyisocyanate and resin reactive therewith, is described. Ground water is often encountered in pole setting and affects polyurethane foam formation by undesirably reacting with polyisocyanate to give a foam of insufficient density and strength. This improvement comprises extending polyurethane components with a nonvolatile water-immiscible material (e.g. hydrocarbon oil) which inhibits the undesired reaction of water and polyisocyanate and reduces the unit cost of the polyurethane foam. The addition to the polyurethane composition of termite repellant materials and preservative agents for the pole is also described.
    • 描述了使用由多异氰酸酯原位形成的发泡聚氨酯树脂和与其反应的树脂在地面中设置或重置极的已知方法的改进。 在极固定中经常遇到地下水,并且通过不期望地与多异氰酸酯反应而影响聚氨酯泡沫形成,得到密度和强度不足的泡沫。 这种改进包括用不挥发性水不混溶材料(例如烃油)延伸聚氨酯组分,其抑制水和多异氰酸酯的不希望的反应并降低聚氨酯泡沫的单位成本。 还描述了添加白蚁防除材料的聚氨酯组合物和极的防腐剂。
