Information monitoring sensing optical cable laid on shallow surface layer and laying system and method

Abstract

The invention provides an information monitoring sensing optical cable laid on a shallow surface layer and a laying system and method.The information monitoring sensing optical cable comprises a buried section, a middle section and an unearthed section, and the buried section and the unearthed section are exposed to the ground; the middle section is arranged on the shallow surface layer and is in close contact with the soil body on the shallow surface layer through the solidified coupling slurry; when the information monitoring sensing optical cable is laid, the information monitoring sensing optical cable is drilled from a soil entering point through a drill bit to form a shallow surface layer channel and then is drilled out of the ground from a soil exiting point, and then the information monitoring sensing optical cable is dragged by the back-dragging drill bit to enter the shallow surface layer channel from the soil exiting point and then is drilled out of the ground from the soil entering point. Wherein the information monitoring sensing optical cable is in close contact with a soil body on a shallow surface layer through the coupling slurry in the dragging process. The information monitoring sensing optical cable arranged on the shallow surface layer is good in coupling performance, and the strain, temperature and vibration sensing precision can be improved.
