The oil path is opened, anti-rust oil is sprayed out through the oil nozzle, the air pipe is moved along the T-shaped groove, the oil pipe integrally coats the inner wall of the T-shaped groove with the anti-rust oil, and the problems that dead corners exist, the T-shaped groove is not completely cleaned, the anti-rust oil is not completely coated, and the maintenance effect of the workbench is affected are solved.

This utility model provides a novel concrete curing watering device, including a lifting platform, a rotating component, and a watering component. The lifting platform is mounted on a movable base; the rotating component is mounted on the lifting platform, and the lifting platform can drive the rotating component to move up and down; the watering component is mounted on the rotating component, and the rotating component can drive the watering component to rotate. The advantages of this utility model are that by setting up a lifting platform, the watering height can be adjusted; by setting up a rotating component, the watering angle can be adjusted. It can not only water and cure concrete on roads, building floors, and low walls, but also water concrete on walls of normal or higher heights, expanding the application scenarios and ensuring curing effectiveness. By setting up a movable water distribution pipe, the watering range can be increased, improving curing efficiency. The structure is simple and the operation is convenient.

The utility model discloses an inflatable shape-adjustable composite maintenance tarpaulin. The composite maintenance tarpaulin comprises a fireproof surface layer, a heat insulation layer, an inflatable shape-adjustable layer, a puncture-proof layer and a moisturizing substrate layer which are sequentially laminated and compounded from top to bottom through an adhesive, a plurality of air chambers are arranged in the inflatable shape-adjusting layer, the air chambers are sequentially communicated through one-way valves, the air chambers located at the two ends are provided with an air inlet connector and an air outlet connector respectively, and valves are arranged at the positions of the air inlet connector and the air outlet connector. The concrete curing device can ensure the curing effect, and can meet the requirement for concrete curing in a cold region or under the extreme heating power condition.

The application is a kind of water conservancy lifting steel wire rope automatic maintenance patrol rope trolley, belonging to the field of steel wire rope maintenance equipment, including a box body, a walking mechanism and an oil brushing assembly, the walking mechanism and the oil brushing assembly are arranged along the length direction of the through hole; the walking mechanism includes at least two clamping walking assemblies, the two clamping walking assemblies are arranged uniformly along the circumference of the through hole in the box body, and the two clamping walking assemblies have a clamping space; each clamping walking assembly includes a fixed rod and a walking wheel, the fixed rod is arranged in the box body along the length direction of the through hole, and the walking wheel is arranged on the fixed rod; the walking wheels of the two clamping walking assemblies clamp and walk on the steel wire rope; by setting the above-mentioned patrol rope trolley, the trolley can automatically walk on the steel wire rope and brush oil, avoiding the problem of traditional manual oil brushing, realizing real-time maintenance of the steel wire rope, and without the need to unload the steel wire rope, which not only has high work efficiency, but also can guarantee the maintenance effect.

The invention relates to the technical field of road materials, and particularly discloses a bio-based cold-laid asphalt thin overlay material and a preparation method thereof. The thin overlay material comprises the following components in percentage by mass: 85%-95% of asphalt pavement milling reclaimed material, 3%-10% of bio-based cold-mixed cementing fluid, 1%-4% of acrylic emulsion and 0.5%-1.5% of glycerin monostearate, the bio-based cold-mixed cementing fluid comprises the following components in percentage by mass: 5%-85% of asphalt, 5%-40% of vegetable oil, 5%-40% of oleic acid monoester and 3%-15% of terpene unsaturated compounds, the iodine value of the vegetable oil is greater than or equal to 100. All the components of the thin overlay material can be mixed under the normal temperature condition, the influence of the construction environment is small, the bio-based cold mixing cementing liquid can recover the performance of aged asphalt of the asphalt pavement and improve the overall performance of the road, and the acrylic emulsion and the glyceryl monostearate can improve the maintenance effect of the asphalt pavement.

This utility model discloses an integrated curing and moisturizing device for basement abrasive-resistant concrete flooring, relating to the field of building technology. Specifically, it includes a curing blanket and an air compressor that come into contact with the basement abrasive-resistant concrete flooring. A waterproof membrane is detachably connected to the top of the curing blanket. Magnetic strips are embedded along all four sides of the curing blanket. A metal mesh is embedded in the top of the curing blanket. Humidity sensors are evenly distributed on the curing blanket. A perforated water injection pipe is embedded in the middle of the curing blanket, with one end connected to a water inlet pipe. The water inlet pipe is connected to the air outlet of the air compressor via a purging pipe. This integrated curing and moisturizing device for basement abrasive-resistant concrete flooring utilizes the magnetic attraction between the sides of the curing blanket and the embedded metal mesh in the top of the curing blanket to prevent the rolled-up curing blanket from unraveling, eliminating the need for manual bundling and saving labor costs.
