Leveraging its strengths in equipment manufacturing and application‑oriented services, Realtop Heavy Industry Co., Ltd. has stepped up market development across Russian‑speaking regions. The company has secured its first trench‑less pipe‑jacking municipal project, a key local livelihood‑driven infrastructure initiative that has drawn notable attention from local authorities. This project fully demonstrates the superior performance of Realtop Heavy Industry’s pipe‑jacking tunnelling equipment, as well as our professional expertise and robust service capabilities for overseas pipe‑jacking construction.
This project forms a core municipal sewage network development scheme within a Russian‑speaking region, featuring a total pipeline length exceeding 5,000 metres with a DN1000 pipe diameter. Upon completion, it will greatly improve the local urban sewage collection and treatment system, optimise the layout of underground municipal pipelines, upgrade livelihood‑related infrastructure, and support urban renewal and ecological improvement.
The construction site features highly complex geological conditions, with alternating layers of hard clay, soft clay, sandy soil, compacted sand and pebble‑bearing strata. Such challenging ground places stringent demands on equipment adaptability, overall performance, construction techniques and on‑site management. To address these complex geological conditions, our company supplied a complete set of Φ1000 slurry‑balance pipe‑jacking machines. Fitted with a centre‑driven, variable‑frequency speed‑regulated composite cutterhead and a secondary crushing mechanism, the equipment is equipped with high‑performance jacking systems, grouting friction‑reduction systems, slurry circulation‑separation systems, intelligent remote‑control operating systems, flexible and reliable deviation‑correction systems, and high‑precision laser guidance systems. It delivers powerful soil cutting and crushing capacity, efficient jacking and slurry‑separation performance, as well as precise operation. The machine adapts well to highly variable complex strata and achieves excellent ground‑settlement control. Supported by sound on‑site technical construction services, smooth, safe and efficient pipe‑jacking operations have been guaranteed throughout construction.
The project is now advancing efficiently and methodically. Work has reached the ninth construction section, with cumulative jacking length surpassing 1,600 metres. The maximum daily advance exceeds 35 meters, and the maximum monthly advance tops 750 meters, meeting all project‑specified construction quality requirements.
To deliver high‑standard, high‑quality project execution, we have built a full‑process, specialised overseas construction‑service guarantee system. Dedicated onsite after‑sales and construction teams are stationed at the project site in the Russian‑speaking region, bringing together seasoned pipe‑jacking technicians and professional project‑management personnel. We have rolled out an integrated service model featuring “high‑quality equipment, premium technical services, precise on‑site management and full‑lifecycle operation and maintenance support”. Drawing on rich overseas project experience, our construction‑service team strictly observes international construction standards to ensure safe and efficient project delivery. It exercises refined quality control over pipe‑jacking operations, dynamically optimises construction schemes, proactively mitigates construction risks, and delivers standardised, localised operation‑and‑maintenance services to sustain stable, high‑efficiency performance of pipe‑jacking tunnelling equipment. This highlights our proven capabilities in overseas project management and specialised field services.
The safe, high‑quality and steady progress of this first trenchless pipe‑jacking project in Russian‑speaking regions marks a major milestone for Realtop Heavy Industry’s local‑market expansion. The equipment has maintained stable core performance even amid harsh, variable geological conditions. This not only comprehensively validates our pipe‑jacking tunnelling equipment for high quality, outstanding stability, high efficiency and reliable safety but also underscores our core competitive edge in integrated overseas engineering services. Moving forward, Realtop Heavy Industry Co., Ltd. will keep advancing along the Belt and Road overseas infrastructure markets. With reliable equipment quality, mature construction technologies and comprehensive localised‑support services, we will facilitate the delivery of more overseas municipal‑infrastructure projects and continuously enhance the global reputation of Chinese‑manufactured trench‑less construction equipment.
