There are a lot of jobs in industry, and many of these jobs are hard for us to imagine, but they are very necessary. Do we know, underwater engineering? In fact, it is the process of doing homework in the water. In fact, the work is very hard. The lower end of the blade foot is more favorable to cut into the soil situation. Underwater engineering production of blade foot data, generally used reinforced concrete. The blade foot is the part of the Caisson force concentration, must have sufficient strength, so as not to produce deflection or damage. Blade foot plane is called tread, its width depending on the soil layer of soft and hard and well wall weight, thickness, such as two, generally not less than 15cm. When it is necessary to pass through hard soil or rock formations, the tread should be maintained with steel plate or angle steel. The tilt angle on the inside of the blade foot is 45℃~60℃.
Whether it is spring, summer, autumn and winter, and no matter the wind and rain, as long as the need for underwater engineering operations, these workers have to go down to the water to carry out homework. Flying shovels more hard. Let's praise these workers. Respect their labor.
