Guided boring—also known as the pilot tube method—is a high-precision, trenchless boring system designed to install underground infrastructure with minimal surface disruption. Characterized by laser-guided accuracy, Guided Boring Machines (GBM) merge the pinpoint control of microtunneling with the space efficiency of directional boring. SINOVO Group engineers heavy-duty horizontal directional boring rigs and foundational drilling tools to support global utilities, pipelines, and civil engineering requirements.
The pilot tube method employs a hollow pilot string target system tracked by a target camera mounted inside the shaft. The guidance computer allows operators to correct deviation in real-time down to millimeter tolerances. Operating within varying soil conditions requires modular configurations. From our advanced SHD45A Horizontal Directional Drilling Rig to crawler core drilling machines, SINOVO designs systems that manage high torque density, heavy thrust loads, and high fluid flow rates.
Modern cities demand minimal surface disturbance. Guided boring and horizontal directional rigs are essential for deep-gravity sewer mains, water distribution grids, electrical conduit installations, and fiber-optic networks. For soft rock formations, clay beds, or water-bearing sand strata, configuring matching drilling buckets, casing extractors, and customized hydraulic pile breakers ensures structural integrity during excavation.
Since the early 1990s, the core engineers and leadership at SINOVO have driven advancements in China’s heavy construction machinery sector. Through strategic alignment, R&D innovations, and joint ventures, SINOVO has grown into a leading manufacturer of geological exploration, water well, and foundation piling machinery.
In 2008, we expanded our footprint by establishing TEG FAR EAST in Singapore, targeting complex Southeast Asian engineering markets. In 2010, SINOVO consolidated its domestic operations with a 120 million Yuan manufacturing facility in the Hebei Xianghe Emerging Industry Demonstration Zone. Spanning 67 mu, this modern factory is situated just 100 kilometers from the Port of Tianjin, optimizing transport costs and container logistics for international shipments.
SINOVO's Beijing and Xianghe bases utilize vertically integrated production lines, which reduce component transit times and optimize quality controls. By sourcing high-tensile steel locally and machining precise electronic hydraulic control blocks in-house, we manufacture robust tools like kelly bars, pile breakers, and casing extractors at competitive price points.
SINOVO core equipment features electronic hydraulic drive systems that respond dynamically to torque fluctuations during drilling operations. Our technology center holds multiple utility patents, ensuring that SINOVO drilling machines deliver efficient horsepower conversion, low fuel consumption, and reduced wear.
Many of SINOVO's heavy rotary drilling rigs utilize custom Caterpillar undercarriages. This enables global operators to access local CAT service centers for hydraulic repairs and undercarriage maintenance, improving uptime on complex jobsites.
Our primary Beijing production facility covers 7,800 square meters and is equipped with over 50 large-scale machining systems. Continuous system modernization allows us to maintain the following annual production capacities:
Urban centers require minimal disruption to roads, light rail lines, and existing structures. SINOVO's horizontal directional drilling (HDD) systems and guided boring tools allow contractors to steer drilling assemblies under rivers, highways, and residential zones without open-cut trenching.
Unlike pressurized conduits, gravity sewer lines require precise alignment. SINOVO's pilot tube target systems allow operators to steer through challenging soil profiles, preventing design deviations that could lead to stagnant flow zones.
To stabilize skyscrapers, bridges, and industrial plants, we provide high-performance rotary piling rigs, casing extractors, dynamic compaction cranes, and customized clay buckets. These tools are engineered to handle high torque demands when boring through hard strata.
All SINOVO heavy engineering products comply with strict international regulatory and safety guidelines. SINOVO has received ISO9001:2015 Quality Management System Certification, European Union CE certification, and Eastern Europe GOST-R certifications.
SINOVO equipment is utilized globally, from soft delta sediments to hard bedrock environments.
We provide relevant product data sheets, technical specification manuals, and casing compatibility reviews to confirm product suitability. Rig solutions can be tailored to meet client project specifications, and third-party pre-shipment inspections are welcome.
SINOVO ensures timely delivery according to commercial contract parameters. Standard product lead times are between 10 to 15 days, with adjustments for custom machinery. Rigs undergo rigorous load and pressure testing prior to shipment.
SINOVO offers a 12-month manufacturer's warranty. During this period, we provide debugging guidance, operator training, and supply critical spare parts. Field technicians are available for site deployment, trial test holes, and operator training programs.
Yes. SINOVO Heavy Industry has its own engineering and R&D team. We can modify structural frames, hydraulic circuits, and software integration to meet specific client geological conditions and operating requirements.
We accept 100% T/T in advance or 100% irrevocable Letter of Credit (L/C) at sight, issued by a major international bank and approved by SINOVO.
We offer a 12-month warranty from the date of shipment, covering major structural components and hydraulic elements. If a defect arises from material or design faults, we will replace the components and provide remote support. The warranty excludes wear items such as hydraulic oils, filters, seals, and wire ropes.
We apply export-standard marine packaging. Heavy frames are secured using steel wire ropes, while sensitive hydraulic cylinders and electrical cabinets are wrapped in anti-corrosion barrier packaging to prevent damage from salt spray.
We can deploy commissioning technicians to the jobsite to assist with setup, training, and testing. Rigs built with Caterpillar undercarriages also enjoy global warranty service compatibility at local CAT centers.
Yes, we maintain a fleet of refurbished, operational machinery. Contact our sales department to check the current inventory of used rotary and core drilling equipment.
SINOVO combines over 30 years of manufacturing experience with professional quality control standards. We maintain close partnerships with international component manufacturers, enabling us to deliver reliable equipment with shorter lead times and global service support.
Yes. Every drilling and piling rig undergoes multi-point testing under simulated load conditions. We issue a comprehensive inspection and test certificate for each machine before it leaves our factory.
Our products carry CE, ISO9001:2015, and GOST certificates, meeting safety and operational standards in Europe, Asia, Africa, and the Americas.
Yes, we are actively looking for local agents and service partners. Qualified companies with experience in foundation and drilling machinery sales are invited to contact us.
Guided boring (GBM) uses a pilot tube system guided by an internal target and a laser to achieve millimeter-level accuracy, making it ideal for gravity sewers. HDD is suited for wider curve paths, longer crossings, and pressurized utility conduits where slight deviations do not affect system performance.
Soft, cohesive soils (such as clay) require specialized tools like clay buckets to prevent soil clogging. Sandy or unstable soil profiles often require continuous flight augers (CFA) or casing tubes driven by hydraulic casing oscillators to prevent borehole collapse during excavation.
