Relevant introduction of fine buckle drill pipe:

Fine buckle drill pipe is a kind of drilling tool that uses alloy steel pipe to thicken the head at both ends, turn small pitch taper thread, and connect with lock joint. It is used in geological exploration field, transmits drilling rig torque to bottom hole drill bit, and is responsible for transmitting drilling fluid. It is applied to geological exploration, water well drilling and geothermal well drilling engineering.

The guiding problem of hard soil layer, sand and pebble layer will be encountered in horizontal directional drilling construction.

The skill of starting operation, when the pilot drill bit passes through the sand, pebble layer and hard layer, when it wants to change the track direction, if it wants to push in blindly, it will cause the drill pipe to bend and the outlet of the horizontal directional pilot drill bit to be blocked. According to the working experience, the operation method of side pushing in with rotation should be adopted, for example, the direction should be upward, then the operator should control the feeding force when the drill pipe is about to bend.
