In the trenchless technology industry, directional drilling has been the main growth area. There are many places in the world, and many industries still recognize the benefits of ordinary non-excavation and directional drilling without trenching. The following is the working principle of non-excavation drilling rig:
The drilling trajectory can be straight or gradually curved. The direction of the Drill Bit can be adjusted when guiding around obstacles or crossing highways, rivers, and railways. The drilling process can be carried out between pre-emerged launch pits and receiving pits, or can be drilled directly from the surface at a small angle on the site where the drill is installed.
Most directional drilling rigs use drilling fluid assisted rock bit drilling pressure applied from the tail of the drill pipe. Drills usually have a bevel so that when the bit rotates continuously, a straight hole is drilled. When the drill bit is kept from rotating in a certain direction, the drill hole is deflected.

Measure tape is a measuring Tool which is commonly used in our daily life, when building, decorating and making wooden furniture, we often use steel tape measures. In fact, besides steel tape measure, there are also other types of tape measures, such as fiberglass tape measure, laser tape measure and ground fiber tape measure.
