Problems solved by technology
[0003] Nowadays, when constructing underground layers with more rocky geological conditions, the drilling speed is very slow, and it usually takes three to five days, or even more than ten days, for one shot. The battery life of ordinary trenchless sensing devices is generally the longest. 24 hours, can not meet the actual operation needs
Under complex geological conditions (such as rock, sand, clay, etc.), due to the very slow drilling speed, the same project length may take days or even weeks to complete, which requires trenchless sensing devices Sufficient battery life, the problem cannot be solved by existing technology

Description
technical field [0001] The invention relates to the field of non-excavation measuring-while-drilling devices, in particular to a non-excavation sensing device and a drill pipe. Background technique [0002] With the large-scale development of urban infrastructure, the application of trenchless technology is becoming more and more extensive, especially in the laying of various pipelines and underground projects such as subway construction. In order to ensure the laying and construction according to the predetermined route, drilling The surface process needs to use the guidance sensor device to guide and measure the position, attitude and temperature of the drill bit. [0003] Nowadays, when constructing underground layers with more rocky geological conditions, the drilling speed is very slow, and it usually takes three to five days, or even more than ten days, for one shot. The battery life of ordinary trenchless sensing devices is generally the longest. It is 24 hours, whic...
