Description
Product Description
The horizontal screw drilling rig is a high-efficiency construction equipment specifically designed for trenchless underground pipeline laying projects. It is widely used in construction projects beneath roads, railways, rivers, and buildings. The equipment employs advanced hydraulic drive technology and is equipped with a load-sensing hydraulic system composed of imported hydraulic components. This system automatically adjusts the output power according to actual working conditions, achieving energy-efficient and high-performance operation.
The entire machine utilizes a hydraulic proportional control system, supporting stepless speed regulation. It is easy and flexible to operate, allowing for precise control of drilling speed and thrust, improving construction accuracy and efficiency. Furthermore, the equipment features a modular frame design, resulting in a compact structure and convenient installation and disassembly, effectively shortening construction preparation time and reducing transportation and installation costs.
This equipment is compatible with both single-wall and double-wall drill pipe construction techniques and can be used with impact drilling tools to achieve stable and efficient drilling in sand, gravel, and hard rock formations, meeting the needs of trenchless construction under complex geological conditions.

Product Function
High-efficiency drilling with top-drive head: The horizontal screw drilling rig utilizes a top-drive head to directly drive the drill bit, providing high torque, stable speed, and strong propulsion, enabling rapid drilling and precise hole formation, improving construction efficiency and borehole quality.
Multifunctional design: It can meet various construction needs such as anchor bolt drilling, anchor cable construction, micropile construction, casing drilling, drainage hole construction, and geological exploration, reducing equipment investment and increasing equipment utilization.
Fully hydraulic intelligent control: The entire machine adopts fully hydraulic drive and proportional control technology, achieving stepless speed regulation and precise operation. Drilling parameters can be flexibly adjusted according to different geological conditions, ensuring construction stability and ease of operation.
Adaptability to complex geological formations: It can be equipped with drilling processes such as impactors and casing follow-up systems, suitable for complex geological conditions such as soil, sand, gravel, weathered rock, and hard rock, meeting diverse construction needs.
Multi-angle drilling capability: The drill frame can be adjusted to different angles, supporting horizontal, vertical, and inclined hole drilling, widely applicable to slope protection, foundation pit anchoring, tunnel pre-support, and other engineering projects.
Casing follow-up wall protection function: When working in loose and easily collapsible strata, drilling and casing follow-up can be completed simultaneously, effectively preventing hole collapse and improving drilling efficiency and construction safety.
Hydraulic clamping and automatic uncoupling function: Equipped with a hydraulic clamping and uncoupling device, enabling rapid connection and disassembly of drill rods, reducing manual labor intensity, shortening auxiliary operation time, and improving overall construction efficiency.
Intelligent safety monitoring function: Real-time monitoring of equipment operating status, with overload protection, fault warning, and emergency shutdown functions, improving equipment reliability and ensuring construction safety.
FAQ
Q: What geological conditions is the equipment suitable for?
A: It is suitable for conventional geological formations such as clay, sand, and gravel. When equipped with an impact drill, it can also be used in weathered rock and hard rock formations.
Q: What is the difference between single-wall drill pipes and double-wall drill pipes?
A: Single-wall drill pipes have a simple structure and are suitable for construction in conventional soil layers; double-wall drill pipes have better slag removal performance and construction stability, and are suitable for complex strata and long-distance construction.
Q: What are the advantages of modular racks?
A: Modular racks are easy to transport and install on-site. They can be flexibly assembled according to the construction space, effectively shortening equipment preparation time and improving construction efficiency.
