Bank protection reinforcing device for water and soil conservation

The utility model discloses a bank protection reinforcing device for water and soil conservation, which relates to the technical field of bank protection and comprises a reinforcing brick, a planting part is arranged on the reinforcing brick, a first lining edge is arranged at the upper end of the inner wall of the planting part, a frame is lapped on the first lining edge, a grid is laid on the frame, and an irrigation part is arranged at the front end of the reinforcing brick. The irrigation part is of a hollow structure, a lifting part is arranged at the rear end of the reinforcing brick, and when the reinforcing brick is laid on the shore, the bottom of the irrigation part of the upper reinforcing brick is in lap joint with the lifting part of the lower reinforcing brick. According to the utility model, the upper and lower adjacent reinforcing bricks are connected through the irrigation part and the lifting part, and the screw holes of the irrigation part and the connecting holes of the lifting part are aligned and fixed through the screw rods, so that the longitudinal connection of the reinforcing bricks is very stable, and the overall reinforcing effect of the revetment is enhanced; and the arranged irrigation part can also serve as a breakwater.

The invention discloses a high-temperature high-pressure high-wear-resistance micro-scanning polar plate structure which comprises a polar plate body, the polar plate body is sequentially composed of a main wear-resistant layer, a main pressure-bearing layer and an insulating coating from outside to inside, a polar plate cover plate is fixedly connected to the face, close to the insulating coating, of the polar plate body through bolts, and a wear-resistant structure is arranged on the outer surface of the main wear-resistant layer. An electric buckle assembly is installed on the outer surface of the main abrasion-resistant layer, and the abrasion-resistant structure comprises a plurality of irregular abrasion-resistant belts arranged on the two sides of the main abrasion-resistant layer. The invention further discloses a manufacturing method of the high-temperature, high-pressure and high-wear-resistance micro-scanning polar plate structure. According to the high-temperature high-pressure high-wear-resistance micro-scanning polar plate structure and the manufacturing method thereof, the problem of unstable insulation caused by unreliable sealing of the existing polar plate structure at high temperature and high pressure is solved.
