Drilling Mobile Toilet

Drilling mobile toilets generally refer to underground prefabricated restrooms or modular underground sewage facilities, specifically designed as eco-friendly sanitation solutions for underground spaces such as coal mines and tunnel construction sites.

Technical Principles and Structure

The frame of an underground mobile toilet often uses low-alloy high-strength structural steel to withstand the humid, highly corrosive, and potentially impactful environment underground, ensuring structural stability and durability. Its core is an integrated sewage system, with common types including:

• Packing type: Automatically packs and seals excreta through mechanical devices, eliminating the need for water flushing or complex piping, effectively preventing odor diffusion and bacterial growth, making it the mainstream choice underground.
• Vacuum suction type: Utilizes negative pressure to quickly suction excreta, reducing residue, but requires supporting vacuum pumps and sealed piping, imposing higher maintenance requirements on the equipment.
• Microbial degradation type: Decomposes excreta through microorganisms to achieve harmless treatment, but requires control of environmental parameters such as temperature and humidity, with relatively limited application scenarios.

Application Scenarios and Advantages

This equipment is primarily deployed in mine excavation faces, tunnel construction sites, and mining living areas, with core advantages including:

• Spatial adaptability: Compact in size, it can be quickly put into use through on-site assembly without damaging the original tunnel structure, suitable for narrow underground environments.
• Safety performance: Complies with fire and explosion prevention standards, with the box body designed to prevent leakage, avoiding contamination of groundwater by excreta or triggering safety hazards.
• Environmental friendliness: The packing and microbial degradation types reduce sewage discharge, reducing reliance on underground drainage systems and meeting green construction requirements.

Industry Standards and Maintenance Requirements

According to safety production regulations, underground mobile toilets must meet the following standards:

• Corrosion resistance: The steel structural frame must be coated with an anti-rust coating, with regular inspections of coating integrity to prevent corrosion-induced structural weakening.
• Flame retardancy: Materials must meet underground fire prevention standards to reduce fire risks.
• Leak-proof capability: Seams on the box body must be sealed to prevent excreta leakage and environmental contamination.

Daily maintenance should focus on:

• Cleaning the packing collection box or vacuum suction tank to prevent blockages or overflow.
• Inspecting the operational status of exhaust fans, lighting systems, and disinfection devices to ensure ventilation and hygiene conditions.
• Regularly lubricating the packing mechanical device to extend equipment lifespan.

Market and Pricing

The market offers a wide range of underground mobile toilets and related accessories, with some products supporting customized designs. Prices range from 160.00 yuan per set to 6509.00 yuan per unit, depending on material, functionality, and configuration requirements.
