1、通风管道安装完成后要保证表面光滑洁净，露在室外的风管要有防雨、防雪措施。

1. After the installation of the ventilation pipe, the surface of the air pipe should be clean and clean. The wind pipe exposed in the outdoor should have the measures of rain proof and snow protection.

2、通风管道伸入结构风道时其末端要安装上钢板网，这样能够防止系统运行时杂物进入通风管道内，通风风管与结构风道缝隙应封堵严密。

2, when the ventilation pipe reaches the structural air duct, the steel plate net should be installed at the end, so that it can prevent the system from entering into the ventilation pipe when running, and the ventilation gap between the air duct and the structural air duct should be tightly blocked.

3、管道穿越沉降缝时应按设计要求加设套管，套管与风管的间隙用填料(软质)封堵严密。

3, the pipe should be added in accordance with the design requirements when the pipe passes through the settlement seam, and the gap between the casing and the wind pipe is sealed with packing (soft).

4、通风管道运输和安装不锈钢，铝板风管时应避免产生刮伤表面的现象，安装时尽量减少与铁质物品接触。此外应避免由于碰撞而产生表面和叶片变形。露天堆放应时要有防雨、防雪措施。

4, ventilation pipe transportation and installation of stainless steel, aluminum plate wind pipe should avoid the phenomenon of scratching surface, installation as far as possible to reduce contact with iron goods. In addition, the surface and blade deformation due to collision should be avoided. There should be rain prevention and snow prevention measures when the opencast is stacked.
