The invention discloses a construction method for a movable mold frame for a lock chamber wall of a ship lock. The specific construction process flow is as follows: carrying out construction preparation, assembling a movable mold frame, assembling a large template, positioning and mounting the large template, concrete pouring a single-section lock chamber wall, a movable mold frame driving the large template to walk to the next section of the lock chamber wall, disassembling the large mold plate, and disassembling the movable mold frame. According to the construction method of the movable mold frame for the lock chamber wall of the ship lock, in cast-in-place gravity type concrete lock chamber wall pouring area, compared with traditional construction adopting all-round scaffolds and simple mold frames, the labor intensity is greatly reduced, the labor amount is reduced, and the construction progress is accelerated; and the movable mold frame operation is simple, convenient and rapid, the safety and stability performance of the movable mold frame are guaranteed, the construction efficiency is high, the construction task of the lock chamber wall is completed by quality guarantee and maintenance in the node construction period, and meanwhile, the whole large template is used, and therefore the appearance quality of the lock chamber wall is effectively improved.

The invention provides lithium ion battery high-voltage anode material preparation and surface coating method. The method adopts high-voltage anode material spinel-type LiNi0.5Mn1.5O4 prepared by a two-step method and comprises the following steps of: firstly, evenly mixing nickel source and manganese source solutions with a surface active agent solution, then drying and roasting in the air of 350-450 DEG C to obtain a precursor of a nickel and manganese oxide; mixing the precursor with a lithium source through liquid phase ball milling, drying and finally roasting in the air of 400-900 DEG C to obtain an anode active material; and adding the anode active material to a soluble aluminum solution containing a lithium source, sufficiently and evenly mixing under controlling the lithium source, the soluble aluminum source and the anode active material to be at the proper mol, drying and carrying out high-temperature roasting treatment to obtain a final product which is the lithium ion battery high-voltage anode material which is coated with a layer of lithium-contained transition metal oxide on the surface. The high-voltage anode material prepared by the method has the characteristics of high initial capacity, good cycle performance and the like.

This invention discloses a preparation method for the positive complex material of Li ionic cells, which applies a surface covering technology to cover an Al2O film of amorphous structure on a positive active substance surface of the Li ionic cells, confects the Al salt and a solvent to a soluble Al salt solution then mixes it with the positive active substance in proportion and mix them uniformly then to get a positive complex material of Li ionic cell with an amorphous structure Al2O film covered on the surface after filtration, sinter and cool naturally, which improves the interface state of the electrolyte and positive active substance and suppresses the badness reaction between the two.

Belonging to the technical field of concrete, the invention provides a water permeable cement concrete and a construction method thereof. The water permeable cement concrete consists of the following raw materials by weight: cement, recycled concrete coarse aggregate, stone, water, fly ash, a water reducer, isocyanate modified phenolic resin, short fiber and sodium bentonite. The water permeable cement concrete provided by the invention uses waste concrete and stone cooperatively to replace natural coarse aggregate, and takes the isocyanate modified phenolic resin as the binder, the added short fiber ensures the water permeability of concrete and simultaneously improves the coarse aggregate interface state of the cementitious material, and improves the concrete strength. The used composite water reducer effectively reduces the use of water under the premise of guaranteeing the concrete flowability and workability, and improves the project quality. The sodium bentonite is used as a thickener, can increase the coagulating force between all the materials, also can be used in combination with other components, and plays a role of strengthening, thickening, tackifying and water retention.
