Leili Horizontal Spiral Drilling Machine – Product Q&A

1.What engineering fields can this Leili horizontal spiral drilling machine be used for?

It is mainly used for horizontal anchor hole drilling for slope protection, horizontal boring on earthen walls and cave dwellings, trenchless crossing drilling for weak current pipelines, horizontal crossing drilling for small water supply and drainage pipelines, horizontal exploration holes for civil engineering, and horizontal hole forming for guardrail foundations and other projects requiring horizontal drilling.

2.The machine is motor-driven, how stable is the whole system?

It adopts high-power industrial motor to deliver continuous and balanced power. The track-chain feeding structure offers stable guiding force and effectively reduces drill rod deviation. Uniform feeding brings favorable straightness of drilled holes, suitable for long-duration horizontal drilling.

3.Can drilling depth be adjusted? Are drill accessories optional?

Segmented spliced spiral drill rods allow users to adjust drilling depth by adding or removing rod sections. Various sizes of drill bits and spiral blades are optional to satisfy different aperture standards.

4.What operational suggestions when drilling in soil mixed with gravel and hard clay?

Gravel soil accelerates wear of drilling tools. It is recommended to reduce feeding speed and drill evenly. When encountering large hard stones, avoid forced propulsion and adjust drilling positions to prevent impact damage to drill bits.

5.Is it convenient to move the machine on outdoor construction sites?

Universal transport casters are installed at the bottom for direct movement on flat mud ground and hardened surfaces. Auxiliary traction or lifting equipment can be adopted for relocation on steep and uneven terrain.

6.What are the core advantages compared with simple handheld augers for horizontal drilling?

The dedicated track support structure eliminates the need for operators to hold the drill steadily with continuous physical effort, greatly reducing fatigue. The guide track limits drill rod swing and achieves better hole straightness. The chain feeding system supports controllable uniform speed, offering higher stability for long-hour continuous work than simple equipment.

7.What maintenance work should be carried out after daily operation?

Clear soil and sediment on tracks, chains and spiral drill rods in a timely manner; regularly lubricate transmission chains and sliding guide rails; check the tightness of frame bolts and drill rod connectors; remove dirt on spiral blades before storage to avoid component rusting.

8.What are the power supply requirements? How to work outdoors without fixed power grid?

The machine is compatible with standard industrial three-phase power supply. When fixed power is unavailable in the wild, a diesel generator with matched power can be equipped to support field construction.

9.Do we need different drill bits for various soil conditions?

Standard spiral drill bits work well in loose loam and soil. For stiff clay and gravel-containing soil, wear-resistant reinforced drill bits are suggested to slow down blade abrasion and improve drilling performance.

10.Is it easy to purchase vulnerable spare parts for the machine?

Consumable parts including spiral drill rods, drill bits, transmission chains and bearings are kept in stock and available for separate purchase and replacement, shortening equipment downtime and ensuring smooth project progress.
