en.Wedoany.com Reported - Recently, Huaneng Sichuan Baoxing River Company initiated the anti-slide pile project for disease control in the reservoir area of the Qiaoqi Hydropower Station. This project involves comprehensive treatment of Main Reservoir Heap No. 1 and Main Reservoir Heap No. 2, marking the entry of the remediation work into the implementation phase. It aims to eliminate safety hazards and ensure the stable operation of the hydropower station.
The Qiaoqi Hydropower Station is located on the upper reaches of the Baoxing River. It adopts a hybrid development model combining a high dam with a large reservoir and tunnel water diversion, with power generation as its primary function. The dam site is on the Dong River, where an earth-core rockfill dam is planned for construction, with a maximum dam height of approximately 120 meters and a regulating storage capacity of 166 million cubic meters. It plays a crucial role in regional energy supply. In March 2023, the Dam Safety Supervision Center of the National Energy Administration pointed out during a regular inspection that Main Reservoir Heap No. 1 and Main Reservoir Heap No. 2 in the reservoir area exhibited creep deformation. To ensure safety, Baoxing River Company launched this disease control project.
The project focuses on the areas of Main Reservoir Heap No. 1 (approximately 115 meters long) and Main Reservoir Heap No. 2 (approximately 145 meters long). Construction content includes prestressed anchor cables, anti-slide pile construction, and supporting temporary works. Concurrently, deformation monitoring, surface displacement monitoring, and anchor cable stress change monitoring will be implemented to track the treatment effectiveness throughout the process until the project passes final acceptance.
To ensure smooth project progress, the project team has organized professional surveys, deepened design drawings based on the structural characteristics of the reservoir area, communicated and demonstrated with the design unit, compiled a special construction plan, and clarified safety, quality, and schedule targets. Currently, all preparatory and construction work is proceeding in an orderly manner.
The commencement of this anti-slide pile project demonstrates the professional capability of the project team and provides experience for similar reservoir area disease control projects. In the next step, the team will strictly control quality and safety, promote the high-quality completion of the project, ensure the stable power generation of the Qiaoqi Hydropower Station, and support regional energy supply.
