Construction fences play a beautiful, clean, and unified role in urban construction, and are now indispensable construction equipment in urban construction. The height of construction fences is usually over 2 meters, commonly 2 meters, 4 meters, 6 meters, and 8 meters, or 12 meters higher.

施工围栏高度在4米以下的，一般采用单柱式，在地下深处挖1米左右的基础，专栏采用直径为140mm和189mm等，施工围栏高度在4米以上的一般采用二柱式，地下深挖的基础通过调整高度来调整，两根柱子采用直径114mm-219mm的柱子，施工围挡表面镀锌，一般采用0.5mm的厚度。

For construction fences with a height of less than 4 meters, a single column type is generally used. A foundation of about 1 meter is excavated deep underground, and columns with diameters of 140mm and 189mm are used. For construction fences with a height of more than 4 meters, a two column type is generally used. The foundation of deep underground excavation is adjusted by adjusting the height. The two columns are columns with a diameter of 114mm-219mm, and the surface of the construction fence is galvanized with a thickness of 0.5mm.

施工围挡的安装设置规范：

Installation and setting specifications for construction fences:
