The invention relates to a masonry structure lintel crack reinforced through steel plate wedges and angle steel supports and a construction method thereof. The masonry structure lintel crack reinforced through the steel plate wedges and the angle steel supports comprises the angle steel supports, the steel plate wedges and batten plates. The angle steel supports are arranged on the lower portion of a masonry structure lintel crack and symmetrically arranged on the two sides of the lower portion of an original structure lintel. The steel plate wedge is composed of a wedge opening and a wedge tail, and the steel plate wedge is symmetrically driven into the deep position of the crack from the two sides of the lintel. The batten plate is tightly attached to the angle steel bracket and is welded; after the angle steel supports, the steel plate wedges and the batten plates are all installed, cement polymerization grouting liquid is poured into the cracks. The steel plate wedges and the angle steel brackets are adopted to reinforce lintel cracks of the masonry structure, tensile stress generated by pressure grouting reinforcement can be borne, the ductility of the structure can be improved, and the anti-collapse capacity of the structure can be enhanced.

The invention relates to a reinforced concrete joist reinforced masonry structure lintel crack and a construction method thereof. The reinforced concrete joist reinforced masonry structure lintel crack comprises a reinforced concrete joist, transverse steel bars and stirrups. The reinforced concrete joists are symmetrically arranged on the two sides of the lower portion of the masonry structure lintel crack. After transverse steel bars in the reinforced concrete joists are bound and fixed through stirrups, concrete is poured into the supporting formworks; after the reinforced concrete joist reaches a certain strength, cement polymerization grouting liquid is poured into the crack; the reinforced concrete joist is adopted to reinforce lintel cracks of the masonry structure, tensile stress generated by pressure grouting reinforcement can be borne, the ductility of the structure can be improved, and the anti-collapse capacity of the structure can be enhanced.

The utility model discloses a detachable hopper water seal tank which comprises a lower movable hopper water seal tank, H-shaped steel, a first connecting seat, a second connecting seat and a water seal tank connecting seat, the lower movable hopper water seal tank is arranged on the lower side of a lower movable hopper steel structure, one end of the H-shaped steel is arranged on the upper side of a walking trolley, and the other end of the H-shaped steel is arranged on the lower side of the walking trolley. The other end of the H-shaped steel is fixedly connected to the side wall of the lower movable hopper steel structure, the top of the first connecting seat is fixedly connected to the lower side of the H-shaped steel, and the bottom of the first connecting seat is detachably connected with the top of the water seal tank connecting seat; the top of the second connecting seat is fixedly connected with the lower movable hopper steel structure, and the bottom of the second connecting seat is detachably connected with the top of the water seal tank connecting seat, so that the problem that the lower movable hopper steel structure and the lower movable hopper water seal tank need to be replaced at the same time is solved, the maintenance workload is reduced, and the maintenance efficiency is improved. And engineering materials and cost are saved.

The utility model relates to a slope protection building block and a slope protection. The slope protection building block comprises a building block main body, an interlocking convex part and an interlocking concave part, the building block body comprises two first end faces located in the longitudinal direction and two second end faces located in the transverse direction. The linkage protruding parts are formed at the two ends of the first end face in a protruding mode in the longitudinal direction, each linkage protruding part comprises a linkage end face, and a limiting concave part penetrating through the linkage end face is formed in the transverse direction; the interlocking concave part is composed of a first end face and side faces of two interlocking protruding parts located at the two ends of the first end face, the shape of the interlocking concave part is matched with the shape of the two interlocking protruding parts when the interlocking concave part and the two interlocking protruding parts are spliced, and a limiting protruding part protruding out of the first end face is formed in the interlocking concave part. Through the design of an interlocking structure, interlocking is formed between the spliced slope protection building blocks, and the stability of the slope protection is improved.

The present application relates to a kind of steel sleeve box formworks for water group pile concrete deck, including side mould, bottom plate and truss beam three parts, bottom plate is made of middle main rectangular frame and two sides auxiliary rectangular frame and is spliced into "*" type, truss beam is spliced into circle by special-shaped truss beam, side mould is divided into upper and lower side mould, and both are spliced by multiple arc-shaped side moulds.The bottom plate of the steel sleeve box formwork of the present application adopts detachable bottom plate structure, when bottom plate is removed, bottom plate frame height can be lowered using lifting device, leaving construction operation platform, which can save engineering materials, and is also beneficial to the convenience of bottom plate removal operation, and truss beam and side mould are both assembled structure, the overall performance requirement of the steel sleeve box formwork of the present application to lifting equipment is relatively small.
