This utility model relates to the field of water conservancy construction technology, specifically a wall-brushing device for concrete anti-seepage walls used in grab bucket excavators. It includes a base plate, with two opposing base vertical plates fixed to the lower surface of the base plate. A first reinforcing plate is fixed between each base vertical plate and the base plate. Two outer wire mesh clamps are fixed to the upper surface of the base plate, and two inner wire mesh clamps are detachably installed between the two outer wire mesh clamps. The two outer wire mesh clamps and the two inner wire mesh clamps correspond one-to-one and are all semi-circular. Several wire brushes, evenly spaced along their arc-shaped edges, are clamped between each outer wire mesh clamp and its corresponding inner wire mesh clamp. Several reinforcing ribs are fixed between the tops of the two outer wire mesh clamps along their arc-shaped edges. This invention solves the problems of existing concrete anti-seepage wall joint treatment where wall brushing, slag removal, roughening, and groove milling require two separate sets of equipment for step-by-step operation, resulting in low construction efficiency, high construction costs, and time consumption.

The application is a kind of impeller blade for full hydrogen strong convection cover type annealing furnace platform fan, which is used to increase the heat obtained by steel coil during the use of full hydrogen strong convection cover type annealing furnace. The blade body of the impeller blade for full hydrogen strong convection cover type annealing furnace platform fan includes vertical flat piece and curved piece, and the curved piece is connected to the upper side of the vertical flat piece. The rear surface of the curved piece is part of a conical surface, and the front surface is parallel to the rear surface. The generatrix of the conical surface is the intersection line of the rear surface of the vertical flat piece and the rear surface of the curved piece. The apex of the conical surface is located between the center line of the impeller and the intersection line. The rotation axis of the conical surface is arranged on the plane perpendicular to the vertical flat piece, and the rotation axis is located behind the curved piece. The optimization design of the structure of the impeller blade makes the impeller meet the requirements of fluid mechanics, high speed and high temperature. In full hydrogen atmosphere, the air volume can reach 60000m 3 / h.

This utility model relates to a structure for treating bridge abutment slab settlement. The pile foundation has piles extending deep into the bearing layer beneath the soft soil foundation. A support wall is located behind the pile foundation and situated on the soft soil foundation. From bottom to top, the pile foundation includes a pile cap, an abutment, and abutment cap. One end of a slab rests on the abutment cap, and the other end rests on the support wall. The support wall has a tenon at its rear to resist the thrust of the telescopic mechanism. A wedge-shaped settlement compensation block and a telescopic mechanism are arranged on the support wall between the slab and the tenon. The lower end of the wedge-shaped settlement compensation block is inserted into the gap between the slab and the support wall. One end of the telescopic mechanism abuts the tenon, and the other end abuts the wedge-shaped settlement compensation block. During its extension, the telescopic mechanism pushes the wedge-shaped settlement compensation block towards the slab to lift the rear of the slab. The advantages are: the structure is reasonably and reliably designed, easy to operate, improves the construction efficiency of treating bridge abutment slab settlement, has low cost, allows for earlier traffic opening, and facilitates residents' travel.
