1、基坑施工必需停止臨邊防護(hù),深度超越2M的基坑施工還必需采用密目式平安網(wǎng)做封鎖式防護(hù)。防護(hù)欄桿必需自上而下用平安立網(wǎng)封鎖, 平安立網(wǎng)封鎖到磚墻頂面高度。

1. Edge protection must be stopped for foundation pit construction, and dense mesh safety net must be used for blocking protection for foundation pit construction with a depth of more than 2m. The protective railings must be blocked with safety vertical net from top to bottom, and the safety vertical net must be blocked to the height of the top surface of the brick wall.
2、一切護(hù)欄用紅白油漆刷上醒目的警示色,鋼管紅白或紅黃油漆間距爲(wèi)20CM,并懸掛提示標(biāo)志,護(hù)欄四周懸掛“制止翻越”、“留神墜落”等制止、正告標(biāo)志
2. All guardrails shall be painted with striking warning color with red and white paint.

3. Prevent personnel from falling into the foundation pit due to accidents. The skirting board outside the foundation pit guardrail is painted with black, yellow or white and red paint, which can be ineffective to warn the surrounding pedestrians or vehicles.
4、一切護(hù)欄用紅白油漆刷上醒目的警示色,鋼管紅白油漆間距爲(wèi)20CM,基坑西側(cè)按刷坡設(shè)一4米寬的平安通道,并懸掛提示標(biāo)志,護(hù)欄四周懸掛“制止翻越”、“留神墜落”等制止、正告標(biāo)志。
4. All guardrails shall be painted with striking warning color with red and white paint. The distance between red and white paint of steel pipes shall be 20cm. A 4m wide safe passage shall be set on the west side of the foundation pit according to the brushing slope, and warning signs shall be hung around the guardrail, such as "stop crossing", "pay attention to falling" and other stop and warning signs.
5、基坑四周應(yīng)明白警示堆放的鋼筋線材不得逾越基坑邊3米范圍戒備線,基坑邊戒備線內(nèi)嚴(yán)禁堆放一切資料。
5. Clear warning shall be given around the foundation pit that the stacked reinforcement wires shall not exceed the guard line within 3M around the foundation pit, and it is strictly prohibited to stack all materials in the guard line around the foundation pit.
