The invention relates to a method for preparing a lithium-enriched lithium manganese oxide solid solution cathode material. The method comprises the following steps of: adding a mixed aqueous solution of nickel salt, cobalt salt and manganese salt into an oxalic acid or oxalate aqueous solution by an oxalate coprecipitation high-temperature solid state method, and stirring and reacting to generate nickel, cobalt and manganese oxalate coprecipitation; performing solid and liquid separation, washing and drying to obtain a nickel, cobalt and manganese oxalate precursor; and mixing and grinding the precursor and lithium salt, drying, baking at high temperature in an air atmosphere, and thus obtaining the lithium-enriched lithium manganese oxide solid solution cathode material. During preparation of the precursor, the proportion of the nickel salt, the cobalt salt and the manganese salt is adjusted, so that the constituents of the lithium-enriched lithium manganese oxide solid solution cathode material can be adjusted flexibly. The preparation method is suitable for large-scale, economic, stable and reliable production of the lithium-enriched lithium manganese oxide solid solution cathode material, has obvious advantages, and is high in practical value.

The invention relates to a method for using compost to decay straw to make plant pot. Wherein, it comprises breaking straw into sections; emerging with water; adding nitrogen and phosphor fertilizers; grafting compost product to decay, breaking, screening and adding additive to obtain pot material; compressing and shaping the material, then removing the mould. The inventive pot has strong flexibility. And its surface can be emerged by acrylate emulsion, to be used in plant cultivation. And the invention uses temperature-different demould technique or lift demould technique, to reduce the cost.

The invention relates to supporting equipment for a lateral mould and a using method of the supporting equipment, in particular to supporting equipment for a bridge precast hollow slab lateral mould and a using method of the supporting equipment. During the pouring of a hollow slab precast pedestal, after fixing parts are pre-buried under the precast pedestal, the hollow slab lateral mould is supported by a jack and adjusting lead screws. The using method of the supporting equipment comprises the following steps: during the concrete pouring of the hollow slab precast pedestal, the fixing parts are transversely pre-buried in the pedestal concrete at intervals of 1 m; during the use, the hollow slab lateral mould is hoisted on I-steel by hoisting equipment to be close to a pedestal slurry sealing pipe, and then, the bottom of the lateral mould is tightly jacked by the jack every other 1 m; one ends, connected with the lateral mould, of the adjusting lead screws are connected with corresponding small channel bars every other 1 m, the adjusting lead screws are rotated to correct the lateral mould until the lateral mould meets construction requirements. According to the invention, the structure is simple, the mounting and dismounting are facilitated, the use is flexible, the performance is reliable, the controllability and randomness are high, the construction efficiency is high, the waste of manpower and material is reduced, and high safety and reliability are achieved.
