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.
