InactiveCN102953396AIncrease contactEnsure safe productionFoundation engineeringButtressReinforced concrete
The invention discloses an insulating and anti-cracking structure and a construction method of a bus buttress of an aluminum electrolytic workshop. The insulating and anti-cracking structure comprises a reinforced concrete buttress (1), rebars (2) and a stirrup (3), the rebars (2) are 40 mm (millimeter) higher than the elevation of a primary casting, encryption stirrups (5) are arranged at the top of the rebars (2) and are welded with the rebars (2), and the thickness of a secondary fine aggregate concrete leveling course (4) is 100 mm. The construction method includes that the elevation of the primary casting is -100 mm of the elevation of a pier top; the rebars (2) need to extend to more than 40mm of the elevation of the primary casting, the stirrup (3) of a construction pier is welded with the rebars (2), three encryption stirrups (5) are arranged at the top of the rebars (2) at an interval of 50mm and are firmly welded with the rebars (2); after strength of the reinforced concrete buttress (1) reaches the design strength, the construction of the secondary fine aggregate concrete leveling course (4) with a thickness of 100mm is carried out.

Technology for producing salted duck eggs
The invention discloses a technology for producing salted duck eggs, and belongs to the field of poultry egg product processing. The technology includes steps of firstly, selecting eggs and cleaning the eggs; secondly, placing the duck eggs, which are thoroughly cleaned at the first step, in clear water, adding sodium chloride and additive auxiliaries into the clear water, and carrying out soakingfor 30-45 min; thirdly, immersing the duck eggs, which are obtained at the second step, in first brine solution, and carrying out primary ultrasonic treatment for 30-50 min; fourthly, cleaning the surfaces of the duck eggs after the duck eggs are secondarily soaked at the third step, then immersing the duck eggs in second brine solution with the concentration of 20-24% and pickling the duck eggsin environments under the pressures of 0.11-0.12 MPa for 6-9 days; fifthly, ultimately carrying out cleaning, drying, packaging and high-temperature sterilization to obtain the packaged salted duck eggs. A weight ratio of the sodium chloride to the clear water is 1:4-5, and a weight ratio of the additive auxiliaries to the clear water is 1:23-35. The technology has the advantages that the time required for pickling the duck eggs can be shortened, accordingly, the obtained salted duck eggs are moderate in saltiness and can be directly eaten by consumers, and the oil content of egg yolk furthercan be increased to a great extent.
