Description
Technical Field
[0001] The utility model relates to the technical field of slope stabilization, in particular to a slope stabilization device for construction of a pumped storage power station project. Background Art
[0002] The pumped storage power station project is a special type of hydropower station project. Its main function is to store and release electric energy. It uses electric energy from low power load to pump water to the upper reservoir, and releases water to the lower reservoir to generate electricity during peak power load periods, thereby regulating the supply and demand balance of the power grid, and playing multiple roles such as peak regulation, valley filling, frequency regulation, phase regulation, energy storage, emergency standby and black start. It can act as a stabilizer and regulator for the safe operation of large power grids, as well as a "charger" to support the rapid development of new energy.
[0003] The construction process of a pumped-storage power station project needs to ensure the stability of the slope. The slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. For the construction of a pumped-storage power station project, it is necessary to bury pipelines and cables. In order to facilitate later maintenance, it is generally not done by pouring concrete, but by pulling a protective net for subsequent maintenance. However, at present, with this form of protective net, when carrying out the maintenance of cables and pipelines in the later stage of the pumped-storage power station, it is still necessary to remove the protective net. After removal by the current method, the protective net is prone to irregular curling and bending due to its own rigidity, and it is difficult to rewind, making it inconvenient to organize and reuse.
