AI Technical Summary

Technical Problem

Existing horizontal directional drilling rigs have complex and costly rescue procedures for stuck drill bits and broken drill rods, and are prone to failure under complex working conditions. They cannot effectively remove stuck drill bits or retrieve broken drill rods, and there is a risk of secondary accidents.

Method used

A two-way traction mechanism is constructed using a drilling rig, drill rod, hole clearing and reamer, and winch. Combined with pre-embedded steel plates and fixed guy wires, a stable mechanical system is formed. The winch pulls the hole clearing and reamer and the drill rod, simplifying the rescue process and improving stability.

Benefits of technology

It has achieved efficient and simplified drill bit rescue, reduced rescue costs, improved the success rate and construction safety in complex working conditions, and avoided secondary accidents.
