Manual hole digging pile construction method
The invention discloses a manual hole digging pile construction method. The manual hole digging pile construction method comprises the steps that the excavation step of a section of pile hole is set: construction of a wellhead concrete retainer is conducted at the set pile hole position; a cantilever type crane and a guardrail are arranged on the two sides of the pile hole correspondingly, and a material taking barrel is connected to the end of a steel wire rope of the cantilever type crane; the section of pile hole is excavated, an anti-falling cover plate is clamped to a pile hole protection wall, and a ventilation device, a drainage device and a crawling ladder are arranged on one side of the cantilever type crane; another section of pile hole is excavated again; if water seepage occurs, drainage is conducted firstly; then the heights of the anti-falling cover plate, the ventilation device, the drainage device and the crawling ladder are adjusted; the air quality of a construction area below the anti-falling cover plate is detected; and if the air quality does not meet the specification, ventilation is carried out until the air quality meets the specification. The method is reasonable in step setting, high in reliability and high in safety during construction, the efficiency of manual hole digging pile construction can be improved, and the actual construction requirement can be met.
本申请公开了一种人工挖孔桩施工方法，包括步骤：设定一段桩孔的开挖步骤；在设定的桩孔位置处进行井口混凝土护圈的施工；在桩孔的两侧分别设置悬臂式吊机和护栏，并在悬臂式吊机的钢丝绳的端部连接取料桶；进行一段桩孔的开挖，将防坠落盖板卡接于桩孔护壁的上，在悬臂式吊机的一侧设置通风装置、排水装置和爬梯；再次进行一段桩孔的开挖；若出现渗水，先进行排水；然后调整防坠落盖板、通风装置、排水装置、以及爬梯的高度；检测防坠落盖板下方的施工区域的空气质量；若空气质量不符合规定，则通风直至空气质量符合规定。本申请的方法步骤设置合理，施工时可靠性高、安全性高，能够提高人工挖孔桩施工时的效率，能满足实际施工需求。
