Engineering enclosure is a facility designed to isolate the construction site from the external environment, making the construction site a relatively enclosed and isolated space.

It varies depending on the construction site and conditions. Construction projects must be fully enclosed, with main roads or areas with high pedestrian traffic not less than 2.5 meters and others not less than 1.8 meters. Generally, semi enclosed construction is more common in municipal projects, where two or three sides are enclosed and one or two sides are open for the entry and exit of construction equipment and materials. How to determine the specific settings based on the bidding documents, drawings, on-site environment, and construction organization design while ensuring safety. For example, suppose a municipal engineering project is located in a busy city, with half of the road being open for traffic and half for maintenance. At this time, it is necessary to completely close it to ensure that no pedestrians enter and cause danger. Assuming a newly built road is located in the suburbs, with one end connecting to the old road and the other end being a wilderness, only a single-sided wall and a door need to be set up at the junction of the new and old roads, and the other three sides can be left open. Fully enclosed enclosure: The entire construction area is enclosed with hard materials to form a fully enclosed wall. Semi enclosed: If one or more surfaces are not enclosed, it is considered semi enclosed.
