"Stay true to our original aspiration and mission," Tianjin Zepu Cement Products Co., Ltd., under the guidance of its leadership, has also adhered to this principle, starting from customer needs, combining theory with practice, and achieving real results in overcoming challenges, successfully completing the supply work for the DN4000 pipeline engineering of the second section of the East Suburb Sewage Treatment Plant relocation project undertaken by Huashui Company.

The Dongjiao Wastewater Treatment Plant is one of the larger semi-subterranean wastewater treatment plants under construction in Asia. Upon completion, it will have a treatment capacity of 600,000 tons per day and a reclaimed water capacity of 100,000 tons per day, fulfilling the mission of urban wastewater purification. Zepo Company is responsible for the supply of the influent and reclaimed water pipeline project, which is a key component of this engineering. This section of jacking pipeline is a project reaching a diameter of 4 meters in the city and even the North China region,穿越方式为采用4.8-meter external diameter and 4-meter internal diameter concrete sleeve, with a 3-meter diameter glass fiber reinforced plastic sand pipe running through it. It crosses the Beijing-Tianjin-Tangshan Expressway elevated road, with a total length of 131 meters.

Tianjin Zebao Cement Products Co., Ltd. has always maintained its role as the main force in overcoming difficulties in key and challenging engineering projects. In response to the production issues of large-diameter pipes, the company strictly controls the critical points in the production process. Without reference data, through constant communication with clients, it continuously adjusts designs and improves techniques based on data issues such as thrust parameters, deviation correction, and grouting volume during pipe jacking. This collaborative effort overcomes difficulties in production, inspection, and even the final delivery process, successfully completing the pipe connection work.
