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

不过实际制作工程围挡广告时有几点忌讳的地方，布局不能过于平，在色彩上尽量鲜艳忌讳整体色调暗淡无光起不到夺目的效果。内容上不能冗长没有内容，空洞无物。然后层次上要清楚不能混乱，

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,

制作注意事项：工程围挡在实际的制作过程当中，不一定是一帆风顺的，有的时候有树木的遮挡，有的时候有街角转弯的限制，那么我们为了能够更好的突出工程围挡的广告效应，那就要因地制宜，制作出适合自己项目的围挡。工程围挡广告的排列要根据项目宣传的实际情况来定，要有比较明晰的排列示意图，这样才能让施工人员和开发商看得清楚明白!

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!

安装注意事项：工程围挡为在围挡安装的时候应当做好安装的前期工作，比如需要将一些绿化的树木移栽到其他地方，以于安装市政施工围挡后稳固，不容易被倒下和避免被大风吹倒，安装市政施工围挡时必须以不影响行人和通行的前提下进行。当施工围挡安装完毕后需要将施工工地和外界彻底隔离，以于不被不相干人等进入施工地域，以免进入施工地区发生危险。安装好施工围挡后请安排专人在安装水工围挡的外部进行巡逻维持因安装围挡引起道路不便的次序。后强调一点在市政施工围挡附近禁止摆放杂物，泥土等不想关的东西，保持市政施工围挡的整洁美观，而不影响市容市貌。

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.
