Recently, the Water Environment Company of STECOL received a patent certificate authorized by the State Intellectual Property Office for the invention of a split spiral pipe jacking machine and associated construction technology.
The invention has helped to solve the problem of normal excavation and construction at road intersections, in old residential areas and under complex geological conditions. It is an environment-friendly technology featured with low noise, safety and high efficiency, as recognized by both the client and local residents.
In 2016, the Maozhou River Comprehensive Renovation Project Team of the company started research on spiral pipe jacking construction. Following series of innovations, four utility model patents and one invention patent have been obtained since then.
