How to overcome

Start site

1

Under the condition of complex water conditions, Jiangku Water Network Construction and Joint Disputes

There are differences in rivers in the western water areas and western western Guangdong water areas. There are differences in the time and space of rainstorms. Through Xijiang water pumping stations, water transmission lines and other projects, the large and medium -sized reservoirs such as Gaozhou, Heidi, and other large and medium -sized reservoirs have formed a "one river, two warehouses and three warehouses and three warehouses and three warehouses. The water supply pattern of separate "separates" builds a large -scale complex water network system covering the 13 districts and counties of 4 cities in western Guangdong. Due to the complicated water conditions, how to improve water supply guarantee by water areas, how to deploy outer water transfer and storage reservoir to achieve the target of water and space balance, need to carry out a large -scale and cross -pastore network of riverside networking. Configuration.

Yunkai plot Multi -phase complex erosion variable wind turbine engineering geological survey and research

The erosion changes revealed by the cloud -opening plot are complex and diverse. There are conventional weathered deep grooves from muddy erosion, and there are rare weathered deep grooves that are closely related to carbonate erosion. The hemps can be metaplasia, which can be highly dissolved. The cause of the erosion and changing belt and its distribution rules are the difficulties of the survey of this project. It is necessary to carry out special engineering geological research to provide important support for engineering design and tunnel support treatment.

Traveling through complex geological conditions, long -distance deep buried tunnel multi -function TBM development and construction

The geology of the cloud opening plot is complex and varied. The water pouring tunnel needs to cross the complex and bad geological segments such as the richer water break and crushing band, the erosion of the deep groove area, the middle and high ground stress, and the rock explosion formation. In order to adapt to the above -mentioned bad geological conditions, the selection of TBM equipment is difficult, and it is necessary to develop multi -function TBM equipment and synchronous lining construction equipment with intelligent perception, card prevention, discharge and support, and establish a rich metamorphosis of soft rocks and rich fault crushing bands. The rapid support and construction technical system of TBM tunnels under the complex geological environment of water breaks and strata must carry out relevant scientific research to provide technical support.

Research and design of the structure of high water pressure tunnel lining under complex hydrogeological conditions

The engineering water drain line is about 500 kilometers long, and the maximum hole of the tunnel is 8.2 meters. The cloud -opening plot and the coastal plain with complex engineering geological and hydrogeological conditions along the line are prominent. The pipe diameter of the pipeline) reached 1420, which is the most long -distance large diameter water adjustment water project in China. How to control the tunnel during the operation period is developed to prevent internal water seepage; how to prevent the tunnel from being stable during the external pressure during the maintenance period. Wait, there are very few cases of similar projects at home and abroad, and research on tunnel surrounding rocks is required to be related to the stability of rocks in tunnels.

Large traffic, large power centrifugal pump research and development and application

The design flow of the single pump station of the water pump station is 22 cubic meters per second, the pump pump has a variable amplitude of 1.3, the single pump power is 48 MW, which has the characteristics of single pump flow and single pump power, high raising and wide variable amplitude. It is the world's largest vertical single -suction single -stage snail shell foul pump. The domestic lack of the corresponding water pump hydraulic model and engineering examples of the 160 -meter -yang segment needs to carry out water pump research to determine the performance parameters and water pump structures with advanced indicators and reliable technology to ensure the safety of the project and exert greater engineering benefits.

Long -distance deep burial pipeline smart operation and maintenance and guarantee

This project forms a huge water supply system connected to the West River and the reservoir along the line through the 500 kilometers of pipelines. It spans 4 cities. The comprehensive perception of electromechanical equipment is difficult, and the construction of information systems is complicated. Specialized intelligent operation and maintenance research is required, and multiple integrated smart operation and maintenance guarantee systems are established to integrate safety monitoring, emergency protection, and convenient operation to ensure the safety, stability and efficient operation of the project.
