1. Balanced layout of spiral air ducts for underground works.
The distribution characteristics of spiral air ducts in underground engineering require the deepening design before construction, Xi'an ventilation duct, Xi'an ventilation duct processing, Xi'an spiral air duct processing, Xi'an ventilation duct processing factory, ventilation duct, spiral air duct processing, and comprehensive arrangement of various spiral air ducts and other pipes to ensure that the installation and construction of spiral air ducts can be successfully completed in a limited space. Before construction, all sections shall be measured on site, the comprehensive layout and section drawing of the pipeline shall be drawn, and the position of each air duct and support hanger shall be accurately located.
Use 3dmax to build an intuitive three-dimensional model of pipeline layout for some passages, halls and other parts. The model is established according to the comprehensive layout and cross-section of the pipeline, and the problems in the comprehensive layout and cross-section of the pipeline are found through the three-dimensional model to achieve reasonable consistency.
The three-dimensional renderings from different angles and the sectional drawings of each section are made into drawings and hung on the corresponding parts of the construction site, so that the construction personnel can intuitively understand the pipeline layout through the renderings and carry out the construction according to the sectional drawings, which greatly improves the quality and efficiency of the technical disclosure, ensures the smooth progress of the construction, reduces the coordination workload and improves the construction efficiency.
2. Production of spiral air duct and pipe fittings.
The underground ventilation project adopts automatic production line to produce spiral air duct, which is fast, good quality, stable performance and long service life. Spiral air duct can be produced with stainless steel strip and galvanized steel strip. Various pipe fittings such as elbows and tees are cut by plasma cutting machine, and the pipe fitting expansion plate can be quickly cut by directly inputting the relevant parameters of the pipe fitting. The seam welding machine will not damage the galvanized layer and interface when closing the plate and splicing various metal plates, especially when splicing the galvanized plate.
Flatness is applicable to various flanging processes. The circular elbow forming machine automatically bites the elbow, which is fast, dense and smooth. The production of all air ducts and pipe fittings has basically realized mechanization, automation and standardization, with high production efficiency, hard quality and beautiful appearance, saving a lot of manpower and materials.
