Tianjin Zhijing Technology Co., Ltd.

　　Tianjin Zhijing Technology Co., Ltd. was established on June 1, 2016. In October of the same year, it was recognized as a Tianjin technology-based small and medium-sized enterprise. In 2017, it won the first prize in the Tianjin Innovation and Entrepreneurship Competition and was shortlisted for the national finals of the Innovation and Entrepreneurship Competition. In May 2018, it was recognized as a national technology-based small and medium-sized enterprise, and in December it was recognized as a national high-tech enterprise. In the same month, it received the finalist award in the 3rd National Intelligent Manufacturing Innovation and Entrepreneurship Competition. In 2019, it won the gold award at the 13th Beijing Invention and Innovation Competition. It owns more than 20 intellectual property rights of various types. 

　　The company's self-developed automated pneumatic dewatering equipment has ended the era of relying on submersible pump assemblies (including submersible pumps, switch boxes, cables, and water meters) for dewatering, greatly reducing safety hazards, significantly improving the image of safe and civilized construction, effectively avoiding energy waste during construction, and advancing wellpoint dewatering from extensive to intensive practices. 

　　With the spiritual philosophy of "Professionalism stems from focus, quality stems from character" and supported by comprehensive after-sales service, the company injects new vitality into the civil engineering dewatering industry and promotes the industry's advancement toward automation, intelligence, and networking.

　　Application Scenarios

　　With the deepening of urbanization, underground space is widely utilized. In most parts of the country, dewatering construction is an essential measure during underground space development. When using wellpoint dewatering, each well requires a switch box and an electric submersible pump for pumping. Electric submersible pumps are placed underwater, making them highly susceptible to damage and posing safety hazards. Due to the large number of dewatering wells—ranging from dozens to hundreds or even thousands—there are many cables connecting the pumps, which poses a significant challenge to on-site safe and civilized construction. During dewatering, the water in the wells decreases gradually, requiring manual on-off operation. Frequent switching increases labor and easily damages the submersible pumps, while infrequent switching wastes electrical energy.

　　Pneumatic dewatering equipment, based on its centralized power output, facilitates the implementation of automation and functional integration. Pneumatic dewatering equipment integrates most of the functions required in dewatering projects, including pumping, vacuuming, metering, adjustable head, adjustable flow, problem self-diagnosis, water level monitoring, risk warning, data collection, and analysis. Its overall safety is unmatched by traditional dewatering equipment, and it inherently embodies safe and civilized construction attributes, better reflecting the green construction concept of safety, energy saving, and environmental protection.
