With the continuous expansion of urban underground space development, trenchless construction technologies such as pipe jacking, horizontal directional drilling (HDD), and large-cross-section rectangular passages have become important methods in municipal engineering. During these construction processes, the stability of mud circulation and the environmental compliance of mud treatment directly affect project quality, construction efficiency, and overall cost. Kosun, leveraging years of experience in manufacturing solid control equipment, introduces professional mud recycling systems for the trenchless industry, helping construction parties improve drilling efficiency, reduce mud loss, and minimize waste slurry discharge, thereby achieving true energy saving and environmental protection.
In pipe jacking projects, especially for large diameters and ultra-long distances, the requirements for mud performance are more stringent. The Kosun mud recycling system can continuously maintain stable mud density and viscosity, balance earth pressure during jacking, reduce formation disturbance, minimize pipeline resistance, and ensure smoother propulsion operations. Simultaneously, multi-stage separation equipment within the system, including shale shakers, desanders, desilters, and centrifuges, effectively separates drill cuttings, increases the reuse rate of the mud, substantially reduces bentonite consumption, and saves significant costs for construction parties.
In the field of horizontal directional drilling (HDD), the HDD mud recycling system designed by Kosun features high-efficiency circulation capabilities, providing clean and stable mud for pilot drilling and reaming operations. This significantly reduces drill string torque and wear, ensuring a stable borehole trajectory. With reduced solids content in the mud, the resistance during pipeline pullback also decreases, leading to a higher success rate for long-distance, large-curvature crossing projects. By minimizing waste slurry discharge, Kosun equipment also helps construction enterprises easily meet environmental compliance requirements.
In the construction of large-cross-section rectangular underground passages, the system likewise achieves high-flow-rate circulation and efficient solid control, preventing mud sedimentation, maintaining excavation face stability, and reducing impact on surface facilities. The combination of mechanized construction and a stable mud system makes tunnel propulsion more efficient and controllable.
The HDD mud recycling system designed by Xi’an Kosun fully integrates the characteristics of directional crossing construction, consolidating equipment such as shale shakers, desanders, desilters, decanter centrifuges, and mud tanks. Utilizing mechanical grading, screening, and solid-liquid separation principles, it achieves high-efficiency purification and recycling of the mud. The treated mud can be directly reused in crossing construction, saving construction costs while reducing waste mud discharge and minimizing environmental impact. Concurrently, Kosun’s systems can be flexibly configured according to different project demands, ensuring stable and efficient mud treatment whether for urban construction or complex terrain operations.
Choosing Kosun’s mud treatment solution not only means improved construction efficiency but also guarantees construction safety and environmental friendliness. With years of technological accumulation and a comprehensive after-sales service system, Kosun assists various directional crossing projects in smooth progression, facilitating the upgrade of mud treatment from traditional methods to mechanized and intelligent solutions, providing robust assurance for urban infrastructure development.
