The application discloses a small and medium-sized reservoir inverted siphon water delivery system and a water delivery method. The system comprises a water delivery pipe arranged along a dam body, a support pier for supporting the water delivery pipe, a rhombic functional cavity, an integrated control cabinet and an energy dissipation mechanism. The water delivery pipe comprises a water delivery pipe section, an intermediate pipe section and a water outlet pipe section. The intermediate pipe section is arranged on the dam top, connected with the rhombic functional cavity and used for guiding water into a high position and storing the water to store energy by forming negative pressure. The water outlet pipe section is connected with the energy dissipation mechanism. The energy dissipation mechanism comprises an energy dissipation well cover arranged at the tail end of the water outlet pipe and an energy dissipation ridge arranged at the rear end of the energy dissipation cover. The integrated control cabinet is used for controlling the rhombic functional cavity. The system is simple, convenient to construct and install, reduces the repair and construction cost of the water delivery pipe in the process of danger elimination and reinforcement of the small and medium-sized reservoir, can deal with the drainage problem in the case of extreme power failure, and provides a low-cost and sustainable solution for the disease and danger caused by aging, damage and leakage of the water delivery pipe.

This utility model belongs to the technical field of rockfall protection shelter structures, and specifically relates to a double-layer protective rockfall collection shelter structure. A double-layer protective rockfall collection shelter structure includes columns, a three-bar support assembly above the columns, a top plate supported above the three-bar support assembly, canopy components at both ends of the top plate, canopy netting supported above the canopy components, and double-wing mesh support components on both sides of the top plate, with double-wing meshting on the double-wing mesh support components. This utility model, through its double-layer protective structure design, ensures that the canopy structure contacts the falling rock first. Using flexible protective netting and other components, the deformation of the netting absorbs and dissipates some of the impact energy of the falling rock. The designed canopy components guide the falling rock to the double-wing meshting on both sides of the shelter, causing the rock to slide down in a specific direction, facilitating centralized rockfall cleanup, preventing the falling rock from scattering and accumulating on roads or power lines, affecting traffic or increasing cleanup difficulty, and reducing the impact on power lines.
