The invention relates to a horizontal self-locking assemble wallboard and a construction method of a horizontal self-locking assemble wallboard embedded into a construction wall body. The horizontal self-locking assemble wallboard is prepared by compounding a glass fiber grid cloth surface enhanced flow-state micropore lightweight concrete basal body and a rock wool heat preservation core plate, wherein the micropore lightweight concrete slurry and the rock wool heat preservation core plate are integrally subjected to gapless tight compounding and one-time pouring moulding; convex groove tenons and concave groove tenons are arranged at the left side, the right side, the upper part and the bottom part of the basal body; during wall formation, the wallboard is combined with each light steel keel having the same size as that of the cross section of each concave-convex tenon, and the light steel keels are placed in the concave-convex tenons of the assemble wallboard so as to form a lightweight wall body embedded with the light steel keels. By utilizing the structural characteristics, the technical problem that steel-structured construction is quickly assembled and constructed to form the wall body is solved, and the wallboard has the characteristics of light weight, high strength, seismic resistance, heat insulation and heat preservation. The steel structure systems can be used for constructing the wall body project having multifunctional requirements on relatively high seismic resistance, energy conservation, fireproofing and the like.

The culture purse seine comprises column piles connected with a seabed and a main net connected with the column piles, wherein the column piles are staggered at two sides of the main net, the cross section of the main net is x-shaped, intersection points are connected through a steel rope, the upper part of the main net is connected with upper ends of the column piles through through lassos, the lower part of the main net is connectedwith the lower ends of the column piles through lassos and is embedded into the seabed, the column piles are fixed with the seabed through pile foundations, and the column piles are fixed with the pile foundations through fixing devices. The culture purse seine provided by the invention can prevent the purse seine from being piled up and wound at different tide levels to avoid damage to nettings,and has the functions of protecting the nettings and preventing the nettings from intertwining with each other; therefore, the stress of the steel rope is more uniform, and the stability and the windwave resistance of the whole structure of the culture purse seine are improved; and the culture purse seine is simple in construction, economic and environment-friendly, and has the advantages of universality and sustainability.

The invention discloses a preparation method of mild reaction type aldehyde ketone resin. The mild reaction type aldehyde ketone resin is prepared by adding a quantitative superbase catalyst into mixed liquid of aldehyde and ketone compounds under the condition of stirring at normal temperature, wherein the reaction process is mild and stable, so the defect that the traditional furfuraldehyde acetone system is easy to implode is overcome. The invention also discloses an application of the mild reaction type aldehyde ketone resin to preparation of an aldehyde ketone resin modified epoxy grouting material. The prepared grouting material can completely exert the flexibility of the aldehyde ketone resin, solves the problem that epoxy resin has high brittleness, can further improve excellent mechanical properties, adhesive property, ageing resistance and corrosion resistance of the epoxy resin, and also has the characteristics of low toxicity, environmental friendliness and the like. In addition, according to the preparation method, the aldehyde ketone resin is prepared in advance and has higher viscosity and thixotropism when being used together with fillers, so the construction process is simple and the aldehyde ketone resin can be applied to concrete surface corrosion of basic facilities such as bridges and ports, restoration of cultural relic, water and seepage prevention, reinforcement and strengthening of buildings and the like.
