In recent years, falling accidents in construction operations have become the main occurrence of accidents in the construction industry. In order to effectively ensure that economic property is not damaged and the personal health and safety of employees are protected, based on the actual situation of the project and the importance of safety protection facilities.

建筑施工中三宝、四口、五临边”防护的具体做法一般是

The specific methods for protecting the "three treasures, four entrances, and five edges" in construction are generally as follows

现场人员坚持使用“三宝”。进入现场人员必须戴帽并系紧帽带，穿胶底鞋，不得穿硬底鞋、高跟鞋、拖鞋或赤脚、高处作业必须系带。

The on-site personnel insist on using the "Three Treasures". Personnel entering the site must wear safety helmets and tie the headband tightly, wear rubber soled shoes, and are not allowed to wear hard soled shoes, high heels, slippers, or bare feet. Safety belts must be worn for high-altitude operations.

做好“四口”的防护工作。在楼梯口、电梯口、预留洞口设置围拦、盖板、架网，正在施工的建筑物出人口和井字架，门式架进出料口，必须搭设符合要求的防护棚，并设置醒目的标志。

Do a good job in protecting the "four ports". Barriers, covers, and nets must be set up at stairwells, elevator entrances, and reserved openings. For buildings under construction that have access to people, well frames, and portal frames, protective sheds must be erected that meet the requirements, and eye-catching signs must be set up.

做好“五临边”的防护工作。五临边指阳台周边，屋面周边，框架工程楼层周边，跑道，斜道两侧边，卸料平台的外侧边。“五临边“必须设置1.0M以上的双层围栏或搭设网。

Do a good job in protecting the "Five Borders". The five edges refer to the perimeter of balconies, roofs, frame engineering floors, runways, ramps, and the outer edges of unloading platforms. The "Five Borders" must be equipped with a double layer fence of 1.0m or above or a safety net.

还有车站站台安装防护围栏负责站台边缘50cm处设置防护围栏，安装牢固的镂空钢丝网，高度1.8米，围栏的设置要求，自土建单位将车站移交给轨道单位施工时，站台防护围栏必须安装以下要求进行防护，如已经安装不符合要求的围栏必须及时调换完成。

In addition, the installation of protective fences at the station platform is responsible for setting up safety protective fences at 50cm from the edge of the platform, installing solid hollow steel wire mesh with a height of 1.8 meters. The setting requirements for the fence are as follows: when the civil engineering unit hands over the station to the track unit for construction, the platform protective fence must be installed with the following requirements for protection. If the fence has already been installed and does not meet the requirements, it must be replaced in a timely manner.

轨行区围栏设置存在的问题，土建单位将车站轨行区交给轨道施工单位后，如果站台下电缆夹层的边墙（靠近轨行区一侧）未施工完成，则进入站台夹层施工的单位需要进行轨行区请点施工，如果已经安装防护围栏等物理隔离，可以不纳入轨行区管理范围。

There is a problem with the fence installation in the track area. After the civil engineering unit hands over the station track area to the track construction unit, if the side wall of the cable interlayer under the platform (near the side of the track area) is not completed, the unit entering the platform interlayer construction needs to carry out the track area construction. If physical isolation such as protective fences have been installed, they can not be included in the track area management scope.

临边防护围栏具体做法如下

The specific methods for edge protection fences are as follows

临边防护栏杆采用钢管栏杆及栏杆柱均采用Φ48* 3.5mm的管材，以扣件或电焊固定。

The edge protection railing is made of steel pipes, and both the railing columns are made of steel pipes Φ 48 * 3.5mm pipe, fixed with fasteners or electric welding.

防护栏杆由二道横杆及栏杆柱组成，上横杆离地高度为1.2米，下横杆杆离地高度为0.6米，立杆总长度1.7米，埋入地下0.5米，立杆间距2米，每隔4米立杆设置一C15混凝土块基础，砼基础尺寸为0.3×0.3×0.5米，立杆居中设置。

The protective railing consists of two horizontal bars and railing columns. The upper horizontal bar is 1.2 meters above the ground, the lower horizontal bar is 0.6 meters above the ground, and the total length of the upright bar is 1.7 meters. It is buried underground for 0.5 meters, with a spacing of 2 meters. A C15 concrete block foundation is set every 4 meters for the upright bar, with a concrete foundation size of 0.3 meters × zero point three × 0.5 meters, with the upright pole centered.

防护栏杆必须自上而下用立网封闭, 立网封闭到砖墙顶面高度。在栏杆下边设置严密固定的高度为30厘米的24砖墙，砂浆抹面。

The protective railing must be closed with a safety net from top to bottom, and the safety net should be closed to the height of the top surface of the brick wall. Set a tightly fixed 24 brick wall with a height of 30 centimeters under the railing, and plaster it with mortar.

所有护栏用红白油漆刷上醒目的警示色，钢管红白油漆间距为20CM，基坑西侧按刷坡设一4米宽的通道，并悬挂提示标志，护栏周围悬挂“禁止翻越”、“当心坠落”等禁止、警告标志。5、基坑周围应明确警示堆放的钢筋线材不得超越基坑边3米范围警戒线，基坑边警戒线内严禁堆放一切材料。

All guardrails are painted with prominent warning colors in red and white paint. The spacing between red and white paint on steel pipes is 20CM. A 4-meter-wide safety passage is set up on the west side of the foundation pit according to the brush slope, and warning signs are hung around the guardrail, such as "No Crossing" and "Beware of Falling". 5. There should be a clear warning around the foundation pit that the stacked steel bars and wires should not exceed the warning line within 3 meters of the foundation pit edge. All materials are strictly prohibited from being stacked within the warning line of the foundation pit edge.
