W.hat Does Sandy Soil Mean?

工程师利用岩土调查和investigations to reveal the soil types of the ground through which a trenchless project will run. Sandy soil contains small particles ranging from 0.05 to 2-mm in diameter. While sandy soil is the easiest ground to excavate and bore, care must be taken to prevent a collapse of the ground due to inadequate support.

岩土工程调查将产生一份报告，指导工程师对如何继续项目以及地面是否需要在项目广泛阶段之前改进。

在砂土中进行硬盘研讨会时，重要的是用更多膨润土调节钻井液的混合物。土壤的孔隙率倾向于使钻井液从孔中逸出到周围地面。然而，调整钻井液混合物可以更有效地密封孔并导致该项目成功。

S.and is also very abrasive, leading to high wear on some components of the drilling rig, especially the drilling head. Pipe ramming is an ideal trenchless method for loose sandy soil because the soil is excavated from within the pipe leaving little opportunity for ground collapse.
