This technology is a construction site restroom system where a construction lift car carries a water supply tank and a septic tank. When the lift car arrives at a floor, it connects to the site restroom via extendable primary and secondary pipes to supply water and extract waste. A control unit operates the lift car's motor based on ascent and descent signals.
Placing portable toilets at high-rise construction sites previously required transporting them via temporary elevators; however, their height often necessitated disassembly and reassembly. Furthermore, high service costs were incurred to pump out waste, and collection was difficult in areas inaccessible to vehicles. Moving toilets while still containing waste also presented significant sanitary issues.
With this technology, when the lift car descends to the ground, a primary vacuum suction system refills the lift's water tank from a ground-based supply. Upon reaching a floor, the primary pipe opens to supply water to the restroom, and the secondary pipe opens to allow a secondary vacuum suction system to draw waste into the lift's septic tank for later transfer to a ground-based tank. This system is ideal for high-rise residential and office construction, large-scale plant sites with workers spread across multiple levels, and sites requiring dedicated women's restrooms. It allows for fixed restroom installations on every floor, enabling water supply and waste removal through lift operations alone, without the need for specialized waste collection vehicles.
This invention was developed with support from the Ministry of Land, Infrastructure and Transport's digital-based construction and safety supervision technology development program.
