施工现场安全通道有什么标准

1、 What are the standards for safety passages on construction sites

　　1、进出建筑物主体通道口应搭设防护棚。棚宽大于道口，两端各长出1m，进深尺寸应符合高处作业安全防护范围。坠落半径（R）分别为：当坠落物高度为2～5m时，R为3m；当坠落物高度为5～15m时，R为4m；当坠落物高度为15～30m时，R为5m；当坠落物高度大于30m时，R为6m。

1. Protective sheds should be set up at the entrance and exit of the main passage of the building. The width of the shed is greater than the entrance, with a length of 1m at each end. The depth dimension should comply with the safety protection range for high-altitude operations. The falling radii (R) are: when the height of the falling object is 2-5m, R is 3m; When the height of the falling object is 5-15m, R is 4m; When the height of the falling object is 15-30m, R is 5m; When the height of the falling object is greater than 30m, R is 6m.

　　2、场内（外）道路边线与建筑物(或外脚手架)边缘距离分别小于坠落半径的，应搭设安全通道。

2. If the distance between the inner (outer) road edge and the edge of the building (or outer scaffold) is less than the falling radius, a safety passage should be erected.

　　3、木工加工场地、钢筋加工场地等上方有可能坠落物件或处于起重机调杆回转范围之内，应搭设双层防护棚。

3. Double layer protective sheds should be erected above woodworking processing sites, steel reinforcement processing sites, and other areas where objects may fall or fall within the range of crane adjustment and rotation.

　　4、安全防护棚应采用双层保护方式，当采用脚手片时，层间距600mm，铺设方向应互相垂直。

4. The safety protection shed should adopt a double-layer protection method. When using scaffolding, the layer spacing should be 600mm, and the laying direction should be perpendicular to each other.

　　5、各类防护棚应有单独的支撑体系，固定可靠安全。严禁用毛竹搭设，且不得悬挑在外架上。

5. Each type of protective shed should have a separate support system, which is reliable and safe to fix. It is strictly prohibited to use bamboo for installation, and it is not allowed to hang on the external frame.

　　6、非通道口应设置禁行标志，禁止出入。施工临时安全通道长度是否有要求

6. Non entrance signs should be set up to prohibit entry and exit. Is there a requirement for the length of temporary safety passages during construction
