Overview

During the installation process of the integrated prefabricated pump station in Rugao, Nantong, the project team innovatively adopted the "BIM+assembly" technology. By simulating the entire installation process in advance through building information modeling, potential problems such as pipeline collisions and equipment positioning were predicted and solved. During on-site hoisting, each component was marked with a QR code, and installation parameters and quality traceability information could be retrieved by scanning. This digital construction method shortened the installation cycle that originally required 20 days to 12 days, and the installation accuracy was controlled at the millimeter level. According to public information from the Nantong Municipal Government, this technology has been promoted throughout the city and has become a "smart worker" in the construction of new urbanization

Product Details

Installation site of Nantong Rugao integrated prefabricated pump stationAt a water conservancy construction site in Rugao District, Nantong City, Jiangsu Province, an integrated prefabricated pump station with a diameter of 3.8 meters and a height of 8.7 meters is being installed in a tight and orderly manner. This modern pump station equipped with a 37KW water pump is a key project implemented by the local government to enhance regional flood control and drainage capabilities, and optimize water resource allocation. At the construction site, machines roar and construction vehicles shuttle back and forth. Workers are carrying out equipment lifting and pipeline docking according to standardized procedures, demonstrating Nantong's technical strength and management level in the field of water conservancy infrastructure construction.

This pump station adopts a modular construction mode of factory prefabrication and on-site assembly. The pump station cylinder is made of high-strength fiberglass material, which has the characteristics of corrosion resistance, leakage resistance, and long service life. Technicians explained that a diameter design of 3.8 meters can meet the needs of high flow drainage and reduce underground excavation area; The vertical height of 8.7 meters has been accurately calculated to ensure stable operation under weather conditions. The selection of the 37KW water pump has undergone multiple scheme comparisons, taking into account both daily drainage needs and emergency response capabilities during sudden heavy rainfall. Its variable frequency control system can automatically adjust the operating power according to changes in water level, saving more than 15% energy compared to traditional pump stations.

Installation site of Nantong Rugao integrated prefabricated pump station During the construction process, the project team innovatively adopted the 'BIM+prefabricated' technology. By simulating the entire installation process in advance through building information modeling, potential issues such as pipeline collisions and equipment positioning were predicted and resolved. During on-site hoisting, each component is marked with a QR code, which can be scanned to retrieve installation parameters and quality traceability information. This digital construction method shortens the installation cycle from 20 days to 12 days, and the installation accuracy is controlled at the millimeter level. According to public information from the Nantong Municipal Government, this technology has been promoted throughout the city and has become a case of 'smart construction sites' in the construction of new urbanization.

The core component of the pump station, the 37KW submersible axial flow pump, adopts multiple technologies. The flow components are made of bi-directional stainless steel casting, and the impeller is optimized by CFD fluid dynamics design, which improves efficiency to 82% while ensuring head. The supporting intelligent control system integrates functions such as water level monitoring, fault diagnosis, and remote control, and can achieve 'unmanned' operation through a mobile app. The staff of Rugao Water Resources Bureau stated that compared to traditional concrete structures, this integrated pump station has a 60% shorter construction period, a 40% reduction in land area, and operates with noise levels below 55 decibels, making it particularly suitable for renovation projects in urban built-up areas.

The safety management at the construction site is also noteworthy. The project party has established a 'dual control' prevention mechanism to ensure operational safety through a dual approach of risk classification control and hidden danger investigation and management. All high-altitude workers are equipped with fall arresters, and the procedure of 'ventilation first, detection later, and operation later' is strictly followed for confined space operations. According to relevant reports from Xinhua News Agency, Nantong's ongoing construction projects have achieved 'zero deaths' for three consecutive years, thanks to the comprehensive implementation of standardized construction systems. As a demonstration project, the safety management experience of this pump station project will be compiled into local standards and promoted throughout the city.

From a broader perspective, the construction of this pumping station will effectively improve the drainage conditions of approximately 5 square kilometers in the old urban area of Rugao. According to hydrological calculations, after the project is put into operation, the regional drainage standard can be increased from the current 1-year return period to a 3-year return period, reducing the risk of waterlogging by more than 70%. According to a public document released by the Development and Reform Commission of Nantong City, during the 14th Five Year Plan period, the city plans to build and renovate 58 integrated pumping stations of this kind, with a total investment of over 1.2 billion yuan. After all are completed, a modern flood prevention system will be formed, which combines source emission reduction, pipeline discharge, and storage and discharge. This intensive construction model has also received special incentive funding support from the Provincial Water Resources Department.

In terms of environmental protection, the pump station design incorporates the concept of sponge city. Rainwater gardens and infiltration ditches are set up around the station area to provide ecological treatment for initial rainwater; The bottom of the pump station is equipped with a sedimentation tank and a grid device, which can effectively intercept solid waste. Monitoring data from the Ecological Environment Bureau of Nantong City shows that the construction and use of pump stations have reduced the average concentration of suspended solids in surrounding rivers by 35%, and the aquatic ecology has been significantly improved. The project leader revealed that they are still experimenting with transforming the pump station roof into a photovoltaic power generation surface to further reduce operational energy consumption.

It is worth mentioning that the project fully considered the coordination with the urban landscape during the construction process. The ground part of the pump station adopts an antique architectural style, which is integrated with the historical and cultural features of Rugao Shuiyuan; Nighttime lighting design avoids light pollution, using 3000K warm toned LED flood lighting. This design concept that emphasizes both functionality and aesthetics has changed the traditional image of water conservancy facilities as' silly, big, black, and rough ', becoming a new landmark for citizens to check in. The Housing and Urban Rural Development Bureau of Rugao City stated that in the future, all municipal public facilities will follow the design principle of 'one facility, one landscape'.

With the completion of the welding of the final outlet pipeline, this integrated prefabricated pump station is about to enter the commissioning stage. Technicians are conducting no-load trial operation on a 37KW water pump, monitoring key parameters such as vibration, temperature, and current. According to the plan, the entire system will be officially put into use before the flood season, adding a reliable water safety barrier to the urban area of Rugao. The smooth implementation of this project not only showcases Nantong's innovative practices in the construction of new urbanization, but also provides replicable model experience for the modernization of water conservancy in small and medium-sized cities in the Yangtze River Delta region. In the future, with the construction and networking of more intelligent pumping stations, Nantong's' Pearl of the River and Sea 'city card will shine even brighter.
