Degradable soil nail and construction method thereof
The invention relates to the technical field of underground engineering, in particular to a degradable soil nail which comprises a soil nail rod body, the interior of the soil nail rod body is hollow, one end of the soil nail rod body is a grouting end, the other end of the soil nail rod body is a grout outlet end, and a soil nail end is arranged at the position, close to the grouting end, of the outer side of the soil nail rod body. The outer side of the soil nail rod body is provided with a plurality of anti-skid pieces which are arranged at intervals in the length direction of the soil nail rod body. According to the technical scheme, the anti-skid piece is arranged on the outer side of the soil nail rod body, the friction resistance between the soil nail rod body and cement grout can be enhanced, the problems that due to the fact that the surface of a degradable material is smooth, the friction force between the degradable material and the cement grout is low, and the tensile requirement is difficult to meet are solved, the tensile capacity of the soil nail is ensured, and the service life of the soil nail is prolonged. And the safety guarantee is higher.
本发明涉及地下工程技术领域，尤其是涉及一种可降解土钉，包括土钉杆体，所述土钉杆体的内部中空，所述土钉杆体的一端为注浆端，所述土钉杆体的另一端为出浆端，所述土钉杆体的外侧靠近所述注浆端的位置处设有土钉端头，所述土钉杆体的外侧设有若干个沿其长度方向间隔设置的防滑件。本发明的技术方案通过在土钉杆体的外侧设置防滑件，能够增强土钉杆体与水泥浆液之间的摩擦阻力，解决了因可降解材料表面光滑，导致其与水泥浆液之间的摩擦力较低，难以满足抗拉要求的问题，确保了土钉的抗拉能力，安全保障性更高。
