The invention discloses a construction method of cast-in-place concrete diagonal braces and prefabricated girts of a strip-shaped foundation pit. Through the adoption of the construction method, the prefabricated girts and the cast-in-place concrete diagonal braces of the strip-shaped foundation pit are connected, and it can be guaranteed that internal force of the girts is effectively transmittedthrough a connecting structure; and meanwhile on the premise of meeting the requirements of the aspects of prefabricated component manufacturing, transporting, mounting and the like, the restraint function to the cast-in-place concrete diagonal braces is achieved, and the function of integrality of a first support structure is enhanced. The stress state of the cast-in-place concrete diagonal braces can be more simplified and tend to theoretical analysis, and site operation and fast mounting can be facilitated. Meanwhile, through prefabricated component splicing, the workload of later chiseling away is reduced, recycling of the prefabricated girts is achieved, the production efficiency is improved, and environment protection, energy saving and emission reducing are achieved; and the construction method is especially suitable for the strip-shaped foundation pit in the soft soil area, the building means of underground engineering are effectively expanded, industry technical progress is promoted, and good economic and social benefits are achieved.

The invention discloses a special low-silicon ultra-low carbon covering agent for car plate steel and a preparation method thereof, and belongs to the technical field of metallurgy. The special low-silicon ultra-low carbon covering agent is prepared from the following components according to mass percent: less than or equal to 3.0% of SiO2, 40.0 to 50.0% of Ca, less than or equal to 1.0% of C, 20.0 to 30.0% of Al2O3, 6.0 to 14.0% of MgO, less than or equal to 3.0% of Fe2O3, less than or equal to 0.04% of S and the balance of inevitable impurities. The special low-silicon ultra-low carbon covering agent has excellent insulation performance, and the defect of easiness in recarburization of the car plate steel is effectively overcome; new materials are added, and the proportion of a formula is optimized, so that the absorption of inclusions in molten steel is effectively increased, the impurity content of billet steel is further reduced, the cleanliness of the molten steel is increased, an innovation demonstration effect is achieved technically, additionally, the product qualification rate of a steel mill is effectively increased, the labor productivity is increased, the working procedure is simplified, and the energy-saving and cost-reducing effects are obvious.

The invention relates to a method for preparing a preserved beancurd product, which belongs to the production field of the preserved beancurds. Primary fermentation and after fermentation are the key steps. The production process of the preserved beancurd comprises the following steps: soybean soaking, jordaning, filtering, warming, refiltration, defoaming, adding coagulant and blank forming, dicing, inoculating, primary fermentation, pickling, bottling, adding soup, covering and after fermentation. The raw materials of GMO free and green food are that protein contained in the soy bean is more than or equal to 38%, slag contained in the soy milk is less than or equal to 15%, crude protein contained in the bean dregs is less than or equal to 28%, and the final temperature of the soy milk in the final siruping tank of overflow tanks is more than or equal to 90 DEG C. When the jellied bean curd is 50%, turning over is carried out slowly and the flow rate of the coagulant is reduced, and when the jellied bean curd is 80%, turning over and the flow of the coagulant are stopped for standing statically; the squeezing is carried out at 8-10Mpa, the moisture content of white blank is 66-73%, the inoculation is carried out at the temperature of 40 DEG C, the primary fermentation is carried out for 36-48 hours and cages are exchanged for three times, and the first exchange, the second exchange and the third exchange are carried out respectively at the temperature of 23-28 DEG C, 22-26 DEG C and 18-22 DEG C. wherein, the relative humidity in the three exchanges are all 60%; pickling is carried out for 3-5 days, then after fermentation is carried out at the temperature of 15-30 DEG C for 45-60 days, and the finished product contains 3.5-18% of salt. The method of the invention can be used for preparing the preserved beancurd.
