Leili Horizontal Spiral Drilling Machine – Track-Type Horizontal Drilling Solution for Efficient Trenchless Horizontal Boring

In projects such as slope anchor construction, underground pipeline crossing and horizontal wall drilling, conventional vertical drilling machines can hardly meet the requirements of continuous horizontal boring. Optimized specifically for horizontal drilling operations, the Leili horizontal spiral drilling machine adopts a track chain feeding structure, delivering a reliable construction solution for all kinds of horizontal drilling work.

Equipped with an industrial-grade electric motor, the machine provides consistent and stable power output with well-controlled vibration, maintaining steady performance during extended working hours. The main body is fitted with steel parallel guide tracks. Driven by chain transmission, the drilling tool advances at a uniform speed, restricting the movement of the drill rod and lowering the risk of hole deviation. Transport casters are installed at the bottom, enabling flexible relocation between drilling positions on flat construction sites and hillsides.

Segmented spliced spiral drill rods are available for assembly. Multiple drill rods and bits with different diameters and lengths can be selected to match varied construction requirements and designed drilling depths. It is widely applied to horizontal anchor holes for mountain slope protection, horizontal boring on earthen walls and cave dwellings, trenchless crossing drilling for small cable pipelines, horizontal exploration holes for foundations, and horizontal piercing for fence foundations.

The frame is welded with thickened section steel with anti-rust coating, suitable for open-air outdoor construction and complex ground mixed with soil and gravel. Forward and backward feeding is easy to operate, and workers can flexibly adjust drilling speed. Compared with manual soil excavation and simple handheld augers for horizontal work, the track support structure reduces continuous physical labor for operators. The spiral blades remove soil continuously and minimize large-scale soil disturbance, forming relatively neat hole walls and facilitating subsequent anchor installation and pipeline laying.

Proper operation and regular maintenance help extend the service life of the machine. It serves as a practical construction tool for scattered small infrastructure projects and batch drilling in slope protection works.
