1. Balanced layout of spiral air ducts for underground works.

地下工程螺旋風(fēng)管的分布特點(diǎn)要求施工前深化設(shè)計(jì)，螺旋風(fēng)管加工綜合布置各種螺旋風(fēng)管等管道，確保螺旋風(fēng)管的安裝和施工在有限的空間內(nèi)順利完成。施工前，對(duì)所有斷面進(jìn)行現(xiàn)場(chǎng)測(cè)量，繪制管道綜合布置圖和斷面圖，準(zhǔn)確定位每根風(fēng)管和支吊架的位置。

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.

用3dmax對(duì)部分通道、大廳等部位建立直觀的管道布置立體模型。根據(jù)管道綜合布置圖和截面圖建立模型，通過立體模型發(fā)現(xiàn)管道綜合布置圖和截面圖的問題，達(dá)到合理一致。

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.

將不同角度的立體效果圖和各截面的截面圖制作成圖紙，掛在施工現(xiàn)場(chǎng)的相應(yīng)部位，使施工人員通過效果圖直觀地了解管道布置，并根據(jù)截面圖進(jìn)行施工，大大提高了技術(shù)交底的質(zhì)量和效率，保證了施工的順利進(jìn)行，減少了協(xié)調(diào)工作量，提高了施工效率。

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.螺旋風(fēng)管及管件的生產(chǎn)。

2. Production of spiral air duct and pipe fittings.

地下通風(fēng)工程采用自動(dòng)生產(chǎn)線生產(chǎn)螺旋風(fēng)管，速度快，質(zhì)量好，性能穩(wěn)定，使用壽命長。螺旋風(fēng)管可采用不銹鋼帶和鍍鋅鋼帶生產(chǎn)。彎頭、三通等各類管件采用等離子切割機(jī)下料，直接輸入管件的相關(guān)參數(shù)即可快速切割出管件展開板?？p紉焊機(jī)閉合板和拼接各種金屬板，特別是在拼接鍍鋅板時(shí)，不會(huì)損壞鍍鋅層和接口。

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.

平整適用于各種翻邊加工。圓形彎頭成型機(jī)自動(dòng)咬合彎頭，速度快，密實(shí)光滑。所有風(fēng)管及管件的生產(chǎn)基本實(shí)現(xiàn)了機(jī)械化自動(dòng)化標(biāo)準(zhǔn)化，生產(chǎn)效率高，質(zhì)量硬，外觀美觀，節(jié)省了大量的人力和材料。

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.
