This invention provides a fireproof flue structure suitable for unlined tunnels, comprising a partition structure erected above the tunnel interior. Both sides of the partition structure are connected to the tunnel wall via supporting structures. The gap between the supporting structures and the unlined section of the tunnel wall is filled with non-shrink grout. The partition structure includes a corrugated steel plate and a cast-in-place concrete partition. The cast-in-place concrete partition is poured onto the upper surface of the corrugated steel plate, serving as the bottom load-bearing layer of the cast-in-place concrete partition during construction. This invention is applicable to unlined tunnels and can minimize construction interference.

This invention relates to a suspended arch bridge main arch ring maintenance work platform, comprising a traveling system, a suspension system, a platform system, and a platform lifting system. The traveling system has a trolley mounted on each side of the main arch ring's top surface, capable of moving along tracks set on the main arch ring. The suspension system is suspended from the two trolleys by cantilever beams. The platform system has two side platforms located on either side of the main arch ring, with the lower platform located below the main arch ring. The lifting system's winch is mounted on the suspension system and connects the side platforms and the lower platform via traction ropes. This invention directly suspends itself on and moves along the main arch ring, avoiding disruption to bridge traffic. Construction personnel can perform comprehensive maintenance work on the main arch ring from the platform.

The utility model discloses a generator set air intake device, including the installation pipe, be equipped with the fan in the installation pipe, the fixed mounting of installation box and mounting seat has on the installation pipe, be equipped with two groups of symmetrical distribution's winding rod in the installation box, two groups winding rod all have the filter screen that has wound, two groups winding rod all have the disc spring that has sleeved, the winding rod upper end has two groups of ratchet that sets up reversely, be equipped with two groups with the ratchet corresponding setting's pawl in the installation box, be equipped with two groups of symmetrical distribution's cleaning brush in the installation box, the cleaning brush is attached with the filter screen outer surface, be equipped with two groups of symmetrical distribution's fixed link in the installation box, realize the conversion to the filter screen at the air inlet through the filter screen cooperation two groups winding rod, keep the clean of filter screen aperture, avoid the influence of the flow of air intake, clean the filter screen surface in time after using through the cleaning brush setting, reduce the input of manual labor.

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.
