The conditions vary according to the construction site. The construction works must be completely closed. The main roads in the urban area or with a large flow of people shall not be less than 2.5m, and the rest shall not be less than 1.8m. Generally, semi closed is more common in municipal works. The so-called semi closed refers to setting fences on two or three sides, and opening one or both sides to facilitate the entry and exit of construction machines and materials. The specific setting shall be determined according to the bidding documents, drawings, site environment and construction organization design under the condition of ensuring safety. For example, if a municipal project is in a busy city, a road maintenance project, half open traffic and half maintenance, it needs to be completely closed at this time to ensure that there will be no danger caused by pedestrians entering by mistake. Assuming that a new road is located in the suburbs, one end is connected with the old road, and the other end is a wild land, it is only necessary to set up a single wall and a door at the junction of the new and old roads, and the other three sides can not be closed. Fully enclosed enclosure: enclose the whole construction range with hard materials to form a fully enclosed enclosure. Semi enclosed: semi enclosed if there is no enclosure on one or more surfaces

不過實際制作工程圍擋廣告時有幾點忌諱的地方，布局不能過于平，在色彩上盡量鮮艷忌諱整體色調暗淡無光起不到奪目的效果。內容上不能冗長沒有內容，空洞無物。然后層次上要清楚不能混亂，

However, there are some taboos in the actual production of Engineering enclosure advertisements. The layout should not be too flat. The colors should be as bright as possible. The overall tone is dim and can not achieve eye-catching effect. The content should not be lengthy and empty without content. Then we should be clear on the level and not be confused,

制作注意事項：工程圍擋在實際的制作過程當中，不一定是一帆風順的，有的時候有樹木的遮擋，有的時候有街角轉彎的限制，那么我們為了能夠更好的突出工程圍擋的廣告效應，那就要因地制宜，制作出適合自己項目的圍擋。工程圍擋廣告的排列要根據項目宣傳的實際情況來定，要有比較明晰的排列示意圖，這樣才能讓施工人員和開發商看得清楚明白!

Production precautions: the actual production process of the project fence is not necessarily smooth. Sometimes there are trees and sometimes there are restrictions on turning at the corner. In order to better highlight the advertising effect of the project fence, we should make a fence suitable for our own project according to local conditions. The arrangement of project enclosure advertisements shall be determined according to the actual situation of project publicity, and there shall be a relatively clear arrangement diagram, so that the constructors and developers can see it clearly!

安裝注意事項：工程圍擋為在圍擋安裝的時候應當做好安裝的前期工作，比如需要將一些綠化的樹木移栽到其他地方，以于安裝市政施工圍擋后穩固，不容易被倒下和避免被大風吹倒，安裝市政施工圍擋時必須以不影響行人和通行的前提下進行。當施工圍擋安裝完畢后需要將施工工地和外界徹底隔離，以于不被不相干人等進入施工地域，以免進入施工地區發生危險。安裝好施工圍擋后請安排專人在安裝水工圍擋的外部進行巡邏維持因安裝圍擋引起道路不便的次序。后強調一點在市政施工圍擋附近禁止擺放雜物，泥土等不想關的東西，保持市政施工圍擋的整潔美觀，而不影響市容市貌。

Precautions for installation: during the installation of the project enclosure, the preliminary work of installation shall be done well. For example, some green trees need to be transplanted to other places, so that the municipal construction enclosure is stable after installation, which is not easy to fall down and avoid being blown down by strong wind. The installation of the municipal construction enclosure must be carried out on the premise of not affecting the safety and passage of pedestrians. After the construction enclosure is installed, the construction site shall be completely isolated from the outside, so that irrelevant people will not enter the construction area, so as to avoid danger in entering the construction area. After the construction enclosure is installed, please arrange a special person to patrol outside the installation of hydraulic enclosure to maintain the order of road inconvenience caused by the installation of enclosure. Finally, it is emphasized that sundries, soil and other things that do not want to be closed are prohibited near the municipal construction enclosure, so as to keep the municipal construction enclosure clean and beautiful without affecting the appearance of the city.
