ZC delivers the Urban Trenchless Mud Recycling System (UMRS), a specialized solid control solution engineered for trenchless and tunnel boring construction in constrained urban environments. This integrated system achieves customizable processing capacities ranging from 60-250m³/h, with precise desanding cut-point ≥45μm and desilting cut-point ≥15μm. Operating at G-force ≤8G with a low-energy optimized power system, UMRS combines vibrating screen and cyclone separation technology to deliver stable mud output while maintaining full compliance with urban construction regulations. Core components adhere to API standards, backed by ISO, HSE, TÜV, and BV certifications.
Traditional settling pits no longer meet modern city center requirements. You face strict zero-discharge mandates and escalating waste disposal fees. Without proper mud recycling, your project encounters rapid equipment wear from high sand content and regulatory penalties from environmental agencies.
UMRS solves these challenges through full-cycle closed-loop processing. The system efficiently separates, purifies, and recycles drilling fluids from shield, horizontal directional drilling, and pipe jacking operations. You reduce new mud consumption by 60%-80% while producing separated water below SS＜70mg/L for reuse or compliant discharge.
This approach meets national environmental protection requirements for reduction, resource utilization, and harmlessness. Your construction team passes environmental inspections smoothly while achieving significant material cost savings.

Your UMRS employs a multi-stage separation system combining cyclone separation, belt filter press, and precision filtration. This configuration efficiently handles solid particles of varying sizes from urban trenchless operations.
The first-stage desander removes coarse solids above 45μm. Following this, the second-stage desilter targets ultra-fine particles down to 15μm. High-performance shakers with fine-mesh screens prevent blinding even in high-clay formations, maintaining consistent separation throughout your operation.
The integrated control panel features one-click operation for startup, shutdown, and parameter adjustment. Digital displays show real-time processing capacity, mud concentration, viscosity, and particle size data. You monitor equipment status through intuitive indicator lights.
The system automatically adjusts processing parameters to maintain optimal performance. Built-in self-protection functions trigger alarms and automatic shutdown during abnormal conditions, preventing equipment damage and ensuring continuous construction progress.
You benefit from integrated mobile design consolidating mud separation, purification, precipitation, and recycling into one compact unit. As the Urban Trenchless Mud Recycling System (UMRS), it occupies only approximately 100 square meters, making it ideal for narrow urban construction sites including city roads, residential areas, and commercial districts.
Modular splicing structure enables quick assembly and disassembly without large hoisting equipment. The mobile chassis allows flexible repositioning according to construction progress. This design adapts perfectly to multi-point horizontal directional drilling projects requiring frequent position adjustments.
All components meet standard container dimensions and road transportation regulations. You transport the entire system efficiently between job sites without special permits or oversized load restrictions. This mobility reduces logistical costs and setup time for your urban trenchless projects.
UMRS specifically serves underground pipeline laying and trenchless reconstruction projects in oilfield well sites and surrounding urban areas. The system handles drilling fluids from horizontal directional drilling, shield tunneling, pipe jacking, and micro-tunneling operations.
Your project benefits from seamless integration with various trenchless equipment. The system processes clay mud and sand gravel mud equally effectively, maintaining optimal rheological properties throughout construction cycles.
Urban rail transit projects require zero-emission mud management in high-traffic areas. UMRS provides contained processing that eliminates environmental contamination risks while supporting night-time operations through low-decibel motor configurations.
Cross-river tunnel and urban pipe network transformation projects leverage the system's ability to maintain consistent boring speeds in abrasive geological conditions. You achieve stable face pressure control through continuous desanding that prevents pump wear and operational downtime.
The full-cycle closed-loop design completely prevents random discharge of waste mud. You eliminate environmental pollution risks while meeting stringent urban environmental regulations. This approach helps your construction unit pass environmental inspections without complications.
Purified mud returns directly to construction operations, dramatically reducing raw material consumption. The separated clear water serves construction needs or achieves compliant discharge standards. Dried mud cake with moisture content below 30% provides material for engineering backfilling, roadbed laying, or conversion into recycled building materials.
You save 60%-80% on new mud purchases through efficient recycling. Reduced waste disposal fees and eliminated transportation costs for fresh water and waste mud removal significantly lower project operational expenses. The system pays for itself through material savings and avoided regulatory penalties.
Urban trenchless mud contains chemical additives and fine solid particles that accelerate equipment wear. UMRS addresses this through wear-resistant alloy construction for separation cylinders, filter screens, and pipelines. Anti-corrosion surface treatments protect against chemical erosion.
This specialized material selection extends service life by 30% compared to standard equipment. You experience fewer replacement cycles and reduced maintenance downtime throughout your project duration.
Single-operator capability reduces labor input and associated costs. The intuitive control interface requires minimal training for your construction personnel. Routine maintenance procedures follow straightforward protocols detailed in comprehensive operation manuals.
