1. The edge protection of the foundation pit guardrail adopts 20 × 30mm square rectangular tube production, guardrail column made of 50 × 50mm (or 40 * 40mm) square tube, with the base firmly fixed to the ground using expansion bolts.
2、基坑临边防护栏立柱高度应不小于1200mm,栏杆高度不小于1200mm,标准长度2000mm每套(一根立柱和一片护栏为一套)或从立柱中道中的距离为2000mm,表面喷有红白或者黑黄警示漆料并在中间位置设置警示标语牌,底部设200mm(180mm)高红白或黑黄相间的挡脚板。
2. The height of the pillar of the edge protection fence in the foundation pit should not be less than 1200mm, and the height of the railing should not be less than 1200mm. The standard length is 2000mm per set (one pillar and one guardrail are a set) or the distance from the middle of the pillar is 2000mm. The surface is sprayed with red, white, or black yellow warning paint, and a safety warning sign is set in the middle. A 200mm (180mm) high red, white, or black yellow foot board is set at the bottom.
3、基坑排水措施要做好,在基坑防护栏杆外侧设置排水沟,采取有效的把水排走,不能在基坑周围有积水防止因积水侵泡而引起基坑边塌方。基坑护栏周边设置夜间警示灯,或在基坑护栏挂有夜间放光装置。
3. The drainage measures for the foundation pit should be taken well. A drainage ditch should be set up outside the protective railing of the foundation pit, and effective measures should be taken to drain the water.

Set up night warning lights around the foundation pit guardrail, or hang night lighting devices on the foundation pit guardrail.
