The invention discloses a construction method for protecting the overpass structure around deep foundation pits, which is intended for the overpass, and comprises the following steps of: constructing a envelop enclosure of long deep foundation pits close to the overpass; Reinforcing the bottom of the deep foundation pits; constructing isolation piles inside and outside the deep foundation pits within the bearing platform range of the overpass; establishing a deep foundation pits support system; Digging the long strip deep foundation pits; And carrying out structural construction on the long strip deep foundation pits. The method can effectively reduce the long side effect of the long strip foundation pit; It can effectively reduce the influence of heavy load around the foundation pits on the envelop enclosure and elevated pier; It can ensure no loss of supporting axial force and strengthen the supporting system; It can reduce the deformation data of foundation pits at the end of construction ...

The invention discloses a multi-stage formation method and system for preparing an anode foil of an aluminum electrolytic capacitor, and the system comprises first-stage to seventh-stage formation tanks for carrying out first-stage to seventh-stage formation treatment, and first-stage to fourth-stage and eighth-stage formation tanks for carrying out first-stage to fourth-stage and eighth-stage formation treatment. A plurality of V-shaped conveying pieces formed by guide rollers arranged in a V shape are arranged in each formation tank, and the contact time of foil materials on the V-shaped conveying pieces and tank liquid in the tanks is 80-120s. According to the invention, more than eight levels of formation can be realized, the processing speed is further improved, the problems of oxide film defects and the like caused by high speed can be solved at the same time, the production efficiency is improved, the production cost is reduced, and the obtained formed foil has a high-quality dielectric ...

The invention discloses a formed foil for an aluminum electrolytic capacitor and a preparation method of the formed foil. The preparation method comprises the steps that a basic sintered foil is placed in a first treatment solution for ultrasonic cleaning and then roasted at 550-580 DEG C, the obtained roasted foil is boiled in a second treatment solution, a second treatment foil is obtained and then subjected to formation treatment, and the formed foil is obtained, wherein the first treating fluid comprises citric acid, polyepoxysuccinic acid and adipic acid with the concentrations of 1-5 g/L, 0.2-0.4 g/L and 0.3-0.8 g/L respectively; the second treating fluid comprises phosphate and borate with the concentration of 0.05-0.5 g/L and the concentration of 0.1-1.0 g/L. According to the invention, the problem of carbide residue in the sintered foil prepared by a wet coating is solved, and the obtained formed foil can further obtain the aluminum electrolytic capacitor anode foil with high specific ...
