Asa council member unit of the China Association for Geological Disaster Prevention and Ecological RestorationSinohydro Foundation Engineering Co., Ltd. has always upheld the concept of "combining prevention and control with green restoration," relying on cutting-edge technological innovation and high-end equipment advantages to deeply cultivate the field of geological disaster prevention and control, and has accumulated rich practical experience in prevention and control projects for landslides, debris flows, collapses, ground subsidence, and the like.

The Sichuan Huatong Bridge,is a controlling project of the G353 reconstruction project of the Baihetan Hydropower Station. The bridge has a total length of 630.26 meters and is a technically difficult and complex composite bridge. In 2022, the right bank slope of the bridge slid as a whole due to the influence of a geological fault zone and reservoir impoundment, causing displacement and deformation of three bridge piers on the right bank, with a risk that excessive deformation would lead to structural damage to the bridge. Sinohydro Foundation Engineering Co., Ltd.overcame difficulties such as hole-forming construction of large-diameter, ultra-deep-hole anti-slide piles under complex geological conditions,and carried out treatment throughthe form of "lattice anchor cables + anti-slide piles + drainage"achieving the expected results.

TibetLaohuzui Hydropower Station,is one of the key construction projects of the Tibet Autonomous Region's "11th Five-Year Plan" power development plan, located on the main stream of the Ba River in Gongbo'gyamda County. Sinohydro Foundation Engineering Co., Ltd. successively undertook five construction tasks, including the civil works and metal structure installation of Lot CII of the main project of the power station, the local collapse treatment project of the downstream slope protective panels, the repair of the plunge pool at the landing point of the spillway discharge water tongue, and the maintenance of hydraulic facilities. Among them, in the local collapse treatment project of the downstream slope protective panels, the concrete face slab was scoured and hollowed out by water flow, causing the face slab to collapse, with an axis length of about 80 meters. The main tasks undertaken included construction roads, earth and rock excavation and backfilling, concrete scour-prevention walls, concrete, reinforcing steel, drilling and grouting, environmental protection and soil and water conservation, and safety monitoring.

TibetJiacha Hydropower Station,is the only large hydropower project put into operation for power generation during Tibet's "13th Five-Year Plan" period, located upstream of Jiacha County seat in Shannan City, Tibet, at an altitude of 3,200 meters. Sinohydro Foundation Engineering Co., Ltd. undertook tasks including part of the cutoff walls, scour-prevention walls, and curtain grouting for the project. During this period, a deformation and downward sliding collapse of about 300,000 cubic meters occurred on the right bank slope of the upstream section of the diversion open channel. Entrusted by the owner, Sinohydro Foundation Engineering Co., Ltd. undertook the emergency rescue task, implemented reinforcement treatment on the slope, and eliminated the hidden danger.

Xinjiang Nuer Water Conservancy Hub,is a controlling project on the Nuer River, a hub project undertaking comprehensive utilization tasks of irrigation and power generation. Sinohydro Foundation Engineering Co., Ltd. undertook the high slope protection treatment and slope reinforcement project.

The Jiangxi Section of the Yangtze River Mainstream Bank Collapse Emergency Treatment Project in Jiangxi Province,isone of the 172 major water conservancy projects and 150 major water conservancy projects of the stateand an important Yangtze River protection project. Sinohydro Foundation Engineering Co., Ltd. undertook the bank collapse emergency treatment of Lot 4 of the project. By adopting the "box-type suspended dumping" construction technique, the underwater bank slope was stabilized, and the water flow was directionally guided and regulated. After the completion of the project, the flood control capacity of the levee was improved, the pressure of flood prevention was reduced, and the benefits of flood control and disaster reduction were remarkable, with good comprehensive social, economic, and environmental benefits.It was awarded the 2024 PowerChina Quality Engineering (Product) Award.
