A seamless structural construction method of a super-long basement belongs to the technical field of building construction, and is characterized in that continuous and staggered construction is performed on the super-long basement based on divided areas and divided stages; earth cutting based on divided areas, foundation pit surface pouring based on divided areas, foundation slab pouring and external wall pouring based on divided areas and arrangement of expansion reinforcing post-cast strips among the divided areas are carried out in sequence, so that the staggered construction is carried out based on divided areas and divided stages, and the construction efficiency is effectively improved; besides, an expansion joint is arranged between every two adjacent bottom surface layers of the basement, and each of the post-cast strips is arranged between every two adjacent foundation slabs of the basement, a high adaptability to expansion and contraction due to temperature changes is achieved, the seamless construction can be carried out, and the construction quality can be effectively improved; methylcellulose is added into nonshrink concrete, the hydration rate is reduced, the heat generation rate is reduced; aluminum nitride powder and quartz powder are added into concrete, the heat release is accelerated, the temperature rise is reduced, and the contraction is reduced.

The invention discloses a fungicide composition with synergistic effect. Active ingredients of the fungicide composition contain (A) tridemorph and one of (B) methoxy acrylate fungicides, wherein the weight ratio of the active ingredient A to the active ingredient B is (32:1)-(1:32). Auxiliaries and excipients are added to the active ingredients to prepare suspension emulsion, suspending agents and the like. The fungicide composition is used for controlling the diseases caused by ascomycetes, basidiomycetes and imperfect fungi germs.

The invention relates to an industrial scale removal method, which comprises the following steps of: preparing 12.0 to 60.0 percent sodium hydrogen carbonate solution, wherein the volume of the sodium hydrogen carbonate solution is equal to 5.0 to 10.0 percent of the volume of a scale removed container; pouring the 12.0 to 60.0 percent sodium hydrogen carbonate solution into the scale removed utensil, fully filling the container with water, stirring the solution for at least 1 minute, heating the solution to the temperature of between 78 and 90 DEG C for the first time, and maintaining the temperature range for over 5 minutes; discharging the solution in the scale removed utensil, and cleaning the container by using clean water; adding anti-scale water into the scale removed utensil, heating the solution to the temperature of between 60 and 85 DEG C for the second time, and maintaining the temperature range for over 10 minutes; and cleaning the scale removed utensil by using the cleanwater. The raw materials are simple, the price is low, the scale removal effect is good, the speed of generating new scales is greatly retarded, and the method is safe and practical.
