围挡是指为了将施工现场与外部环境隔离开来，使施工现场成为一个相对封闭的空间所采取的措施。

Fencing refers to the measures taken to isolate the construction site from the external environment and make it a relatively enclosed space.

在城市建设中，都会用到围挡，起到一种美化整洁统一的作用。围挡的颜色画面适用范围一定要按照当地市政管理部门的要求来制作，一般围挡的高度不得低于1.8米，常见的有2米，4米，6米和8米，或更高的12米等，围挡表面张贴该项目的效果图宣传画面或用于城市公益广告等。一则好的围挡广告，可以为项目营造自身形象，并辅助项目宣传。

In urban construction, fences are often used to beautify, clean, and unify the environment. The application range of the color screen of the fence must be made according to the requirements of the local municipal management department. Generally, the height of the fence should not be less than 1.8 meters, commonly including 2 meters, 4 meters, 6 meters, and 8 meters, or higher than 12 meters. The fence surface should be pasted with a promotional image of the project or used for urban public service advertising. A good fence advertisement can create its own image for the project and assist in its promotion.

常见的围挡依材质不同可分为金属围挡PVC围挡水马围挡等；依用途不同可分为地铁围挡工程围挡建筑围挡围挡等。

Common fences can be divided into metal fences, PVC fences, water horse fences, etc. according to their different materials; According to different purposes, it can be divided into subway enclosure engineering, building enclosure, shopping mall enclosure, etc.

金属围挡金属围挡一般指彩钢板制成的围挡，彩钢板是一种带有有机涂层的钢板，具有耐蚀性好，色彩鲜艳，外形美观，加工成型方便及具有钢板原有的强度等优点而且成本较低。

Metal fence generally refers to a fence made of colored steel plate. Colored steel plate is a type of steel plate with organic coating, which has good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, and has the advantages of the original strength of the steel plate, and low cost.

施工注意事项：

Construction precautions:

宜在深基坑影响范围内人员流动较密集区域选用彩钢板；

Color steel plates should be selected in areas with high personnel flow within the influence range of deep foundation pits;

施工区生活区围挡在市区一般不低于2.5m，其他地方一般不低于1.8m；

The enclosure of the living area in the construction area is generally not less than 2.5m in the urban area, and generally not less than 1.8m in other places;

彩钢围挡立柱间距不宜大于3.6m，施工活动围挡应进行抗风计算；

The spacing between the color steel fence columns should not exceed 3.6m, and the construction activity fence should be subjected to wind resistance calculation;

施工活动围挡使用单位应定期进行检查，当出现开裂沉降倾斜等险情时，应立即采取相应加固措施；

The unit using the construction activity fence should conduct regular inspections. When there are dangerous situations such as cracking, settlement, and tilting, corresponding reinforcement measures should be taken immediately;

不应在彩钢板等轻质围挡或紧靠围挡架设广告或宣传标牌。如确需架设的，受力体系应当独立，并经设计计算。

Advertisements or promotional signs should not be installed on lightweight enclosures such as color steel plates or adjacent to them. If it is necessary to install it, the force system should be independent and calculated through design.

施工注意事项：

Construction precautions:

围档安装前通常是土建已形成交付的下部基础，可采用机械式胀栓化学螺检等方式将立柱钢衬底板固定在下部基础的中心部位作直线均布。

Before the installation of the fence, it is usually the lower foundation that has been formed and delivered by the civil engineering. Mechanical expansion bolts, chemical screw inspection, and other methods can be used to fix the steel lining bottom plate of the column to the center of the lower foundation for uniform distribution in a straight line.

如围档的下部基础尚未形成，建议将立柱钢衬增加长度直接预埋在墙体内，待墙体养护期后即可正式施工；或预制预埋件敷设在墙体平面以后将立柱钢衬用电焊方式与预埋焊接，这两种方式特点是较螺栓连接更为牢固，但预设时必须注意直线与水平线。

If the lower foundation of the fence has not yet been formed, it is recommended to increase the length of the column steel lining and directly embed it in the wall. Construction can be officially carried out after the wall curing period; Alternatively, after laying prefabricated embedded parts on the wall surface, the steel lining of the column can be welded to the embedded parts by electric welding. These two methods are characterized by being more secure than bolted connections, but attention must be paid to straight and horizontal lines during presetting.

立柱钢衬的间距须与设计尺寸一致，保证预装配的半成品能与之连接。

The spacing of the column steel lining must be consistent with the design dimensions to ensure that the pre assembled semi-finished product can be connected to it.

水马围挡水马围挡按照国内通行样式和规定尺寸制作，表面整洁醒目可视性强。

The water horse fence is made according to the domestic standard style and specified size, with a clean and eye-catching surface and strong visibility.

塑料围挡主体部分为蓝色或红色或黄色，（也可根据需求配以各种颜色），造型上可根据各施工现场的区域和特点，作不同造型和色彩上的变化。

The main body of the plastic fence is blue, red, or yellow (various colors can also be matched according to needs), and the shape can be changed in different shapes and colors according to the area and characteristics of each construction site.
