          1、基坑護欄臨邊防護采用20×30mm方方矩管制作,護欄立柱采用50×50mm(或40*40mm)方矩管,底座使用膨脹螺栓與地面固定牢靠。
          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、基坑臨邊防護欄立柱高度應不小于1200mm,欄桿高度不小于1200mm,標準長度2000mm每套(一根立柱和一片護欄為一套)或從立柱中道中的距離為2000mm,表面噴有紅白或者黑黃警示漆料并在中間位置設置警示標語牌,底部設200mm(180mm)高紅白或黑黃相間的擋腳板。
          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,在基坑防護欄桿外側設置排水溝,采取有效的把水排走,不能在基坑周圍有積水防止因積水侵泡而引起基坑邊塌方?;幼o欄周邊設置夜間警示燈,或在基坑護欄掛有夜間放光裝置。
          3. The drainage measures for the foundation pit should be taken well.
