Low-cost long-service-life rapidly-built pumped storage power station

Abstract

The invention discloses a low-cost long-service-life rapidly-built pumped storage power station and belongs to the field of underground engineering. According to the low-cost long-service-life rapidly-built pumped storage power station, an underground reservoir of the pumped storage power station is built; as for the diameter within 3 meters, a rock core is taken out through a center water drill splitter, a rock barrel is cut by an arc-shaped cutter, each rock barrel cutting saw longitudinally cuts segments, and central saws transversely separate the segments; as for the diameter of 3-20 meters, a middle cutterhead is adopted to support a finished hard rock wall, and a rear support propelling cutterhead rotates to cut and separate the segments in the middle layer; and as for the diameter of more than 20 meters, a large cutterhead supports a finished middle cutterhead rock wall, rear support propelling rotating is carried out to cut and separate the segments, and a discharge system discharges the segments. Enhanced segmental lining finished rock wall is manufactured by using hard rock in tunneling space, and sales income of the remaining segments offsets investment. According to theunderground pumped storage power station, the construction cost is lower than that of the prior art by 30%, the service life is 10 times that of a concrete material, compared with the prior art, theconstruction speed is increased by more than one time, and the problems of high construction cost, short service life, low construction speed, high use cost and the like of the pumped storage power station in the prior art are solved. According to drainage systems of various countries, sewers can still be used after 2500 years in Roman.

Description

technical field [0001] A low-cost, long-life, fast-build hard-rock pumped-storage power station belongs to the technical field of clean energy storage applications, specifically a low-cost, long-life, fast-build tunnel-type series-parallel underground reservoir pumped-storage power station. Background technique [0002] The pumped storage power station is a hydropower station that uses the low power of the power load to pump the water from the lower reservoir of the pumped storage power station to the upper reservoir of the pumped storage power station, and then puts the water stored in the upper reservoir to the lower reservoir to generate electricity during the peak power load. Pumped storage power station. Pumped storage power stations can effectively adjust the structural adjustment requirements of wind power, photovoltaic power generation, thermal power generation, and nuclear power generation. my country has built a large number of pumped storage power stations, such a...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems described in the existing excavation technology, the present invention provides a low-cost, long-life and fast construction of hard rock tunnels in series and parallel underground reservoirs. This new technology uses the existing large reservoirs on the ground, large rivers, and the sea as pumping The reservoir of the energy-storage power station can reduce the cost of the pumped-storage power station by more than 10%; the use of new technology to make full use of the hard rock resources in the excavation space of the underground reservoir can build a low-cost, long-life and fast-constructed tunnel-type series-parallel underground reservoir, which can further reduce the current cost. There are more than 10% of the cost of the construction technology; the hard rock in the excavation underground reservoir space can be made into segments, and the segments are reinforced with basalt fiber composite materials and returned to the excavation space for lining, saving the investment in purchasing segments; the remaining segments can be sold directly or Made into reinforced composite material segments for sale, which can reduce the cost of building a pumped storage power station by more than 30% compared with the existing technology; the present invention cuts the hard rock resources of the underground reservoir in the prior art into construction waste discharge expenditures, and transforms it into the present invention. The sales income of hard rock reinforced composite material segments made from hard rock resources solves the problems of high construction cost, short service life and slow construction speed in the existing technology of tunneling underground reservoir hard rock technology
