The soil nail has asperities formed on the outer surface thereof to improve the pullout capacity of the soil nail. The asperities can take a number of forms to include indentations, deformations and threads formed on the outer surface of the soil nail. Optionally, a stinger may be attached to a distal end of the soil nail to further enhance the pullout capacity of the soil nail. | 2010-03-04 |
20100054867 | MESOPOROUS MICROPARTICLE AGGREGATES AND METHODS OF MAKING AND USING THE SAME - An aggregate of mesoporous microparticles that comprises two or more of covalently bound mesoporous microparticles is described. The aggregate of mesoporous microparticles can be used for many applications, including slowing or reversing desertification. | 2010-03-04 |
