圍擋是指為了將施工現場與外部環境隔離開來，使施工現場成為一個相對封閉的空間所采取的措施。

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

在城市建設中，都會用到圍擋，起到一種美化整潔統一的作用。圍擋的顏色畫面適用范圍一定要按照當地市政管理部門的要求來制作，一般圍擋的高度不得低于1.8米，常見的有2米，4米，6米和8米，或更高的12米等，圍擋表面張貼該項目的效果圖宣傳畫面或用于城市公益廣告等。一則好的圍擋廣告，可以為項目營造自身形象，并輔助項目宣傳。

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.

常見的圍擋依材質不同可分為金屬圍擋PVC圍擋水馬圍擋等；依用途不同可分為地鐵圍擋工程圍擋建筑圍擋圍擋等。

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.

金屬圍擋金屬圍擋一般指彩鋼板制成的圍擋，彩鋼板是一種帶有有機涂層的鋼板，具有耐蝕性好，色彩鮮艷，外形美觀，加工成型方便及具有鋼板原有的強度等優點而且成本較低。

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.

施工注意事項：

Construction precautions:

宜在深基坑影響范圍內人員流動較密集區域選用彩鋼板；

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

施工區生活區圍擋在市區一般不低于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;

彩鋼圍擋立柱間距不宜大于3.6m，施工活動圍擋應進行抗風計算；

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;

施工活動圍擋使用單位應定期進行檢查，當出現開裂沉降傾斜等險情時，應立即采取相應加固措施；

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;

不應在彩鋼板等輕質圍擋或緊靠圍擋架設廣告或宣傳標牌。如確需架設的，受力體系應當獨立，并經設計計算。

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.

施工注意事項：

Construction precautions:

圍檔安裝前通常是土建已形成交付的下部基礎，可采用機械式脹栓化學螺檢等方式將立柱鋼襯底板固定在下部基礎的中心部位作直線均布。

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.

如圍檔的下部基礎尚未形成，建議將立柱鋼襯增加長度直接預埋在墻體內，待墻體養護期后即可正式施工；或預制預埋件敷設在墻體平面以后將立柱鋼襯用電焊方式與預埋焊接，這兩種方式特點是較螺栓連接更為牢固，但預設時必須注意直線與水平線。

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.

立柱鋼襯的間距須與設計尺寸一致，保證預裝配的半成品能與之連接。

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.

水馬圍擋水馬圍擋按照國內通行樣式和規定尺寸制作，表面整潔醒目可視性強。

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.

塑料圍擋主體部分為藍色或紅色或黃色，（也可根據需求配以各種顏色），造型上可根據各施工現場的區域和特點，作不同造型和色彩上的變化。

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.
