Description
Product Introduction
The BHD-290L is an annual new product launched by our company. The maximum diameter through which the clamping device of this drilling rig can pass is 430mm, and the longest travel distance of the power head can reach 10.5 meters. It can achieve 10-meter vertical hole drilling with one rod to the end, eliminating the need for frequent disassembly of the drill pipe and improving construction efficiency. A two-section combined tower frame is adopted, which is detachable and also takes into account the construction of inclined holes. In terms of auxiliary control, it is equipped with a drilling Angle display, which can constantly monitor the mast Angle and improve the drilling accuracy. The operation console can be rotated and raised, which is convenient for the operator to observe the hole opening.

Product Details
Product Applications
With its large-bore capacity and modular mast design, the BHD-290L is ideally suited for critical construction tasks in the following areas:
- Foundation Engineering: Tunnel bolt rig is widely used for the construction of large-diameter cast-in-place piles and micropiles for high-rise buildings, bridges, and wharves.
- Slope Anchoring and Excavation Support: Capable of high-precision, multi-angle drilling for high-slope stabilization and anti-uplift anchors (or cables) in deep foundation pits.
- Tunneling and Underground Engineering: Suitable for tunnel pre-support, pipe-roofing construction, and anchor hole drilling for diaphragm walls.
- Geohazard Mitigation: Demonstrates high operational efficiency in landslide remediation, anti-slide pile installation, and various emergency reinforcement projects.
Product Advantages
- Core Benefits: Efficiency increased by over 30%, significantly reduced labor costs!
- One-stop drilling, time-saving and efficient: The power head has a maximum stroke of up to 10.5 meters, easily achieving 10-meter vertical hole drilling. No frequent downtime for disassembling and splicing drill rods is required during construction, effectively eliminating wasted auxiliary time and significantly shortening the single-hole construction cycle.
- Versatile and versatile: The unique two-section modular tower design not only meets the high-efficiency requirements of conventional vertical hole operations but also flexibly handles various complex inclined hole constructions, resulting in higher equipment utilization.
- High-precision monitoring ensures high hole formation rate: The digital auxiliary control system makes the mast status "transparent," avoiding hole deviation caused by visual errors, significantly improving hole quality and acceptance rate.
- Humanized design reduces labor intensity: A fully optimized operating field of vision and comfort allows operators to maintain a highly efficient and safe state of focus for extended periods.
FAQ
Q: What is the accuracy of the angle display system? Is it prone to damage in harsh jobsite environments?
A: The drilling angle display system utilizes industrial-grade sensors that are waterproof, shockproof, and dustproof, achieving an accuracy of ±0.1°. The sensors are encased in high-strength metal protective housings that effectively withstand mud splashes and accidental impacts on the jobsite, ensuring stable data transmission.
Q: How stable is the tower during actual inclined hole drilling operations, given the power head's 10.5-meter stroke?
A: The BHD-290L features a heavy-duty reinforced chassis and a low center of gravity. Its two-section modular tower utilizes high-strength pins and locking mechanisms at the connection point; combined with hydraulic outriggers, this design effectively dissipates torque and ensures mast stability-even when drilling at the maximum inclination angle with the power head extended to the full 10.5-meter stroke limit.
