How to Determine the Cutting Line for the Membrane Cover of the Sewage Tank?

Sewage pond membrane capping is a new type of sewage pond waste gas treatment plan. This kind of anti-hanging membrane structure waste gas treatment plan fundamentally avoids the corrosion of the steel structure by the waste gas in the sewage pond. The principle of the membrane material is used to remove the steel As for the outer layer of the membrane material, the structure prolongs the service life of the steel structure and improves the performance advantages of the anti-hanging membrane structure. But it should be noted that when using a membrane structure to deodorize exhaust gas, the exact position of the cutting line must be determined to avoid waste of membrane materials.

The production and development process of cutting analysis and form-finding technology are very similar. They both start from measuring the physical model. For simple and regular developable surfaces, geometric methods can be used directly to expand them. The modern conceptual tailoring analysis mainly depends on the development of computer technology.

The problem of finding the geodesic on a curved surface is actually a problem of finding the functional extremum of the length of the curve between two points on the curved surface. Due to the novelty and change of the geometric shape of the membrane structure, it is impossible to obtain the explicit expression of the curve length between two points on the surface. Therefore, the extreme value is usually determined to determine several points on the geodesic line, and then the linear interpolation method is used to obtain The middle point to obtain the geodesic.
