人工挖孔桩防护网
摘要：
人工挖孔桩防护网，涉及建设施工安全保障设备，尤其是一种人工挖孔桩的防护设备。本实用新型的人工挖孔桩防护网，其特征在于该防护网形状为弧面，弧面高H大于桩基孔直径1/3，小于桩基孔直径1/2。所述的人工挖孔桩防护网弧周边外框由角钢构成，网面为钢丝网，钢丝网下由螺纹钢筋支撑。该人工挖孔防护网的半径随桩基孔的大小而定，太小则起不到安全防护作用，太大则不易提升吊渣桶。
摘要（英）：

The utility model provides a protection net for manual pile digging operation, relates to insurance equipment for building construction, in particular to protection equipment for manual pile digging operation. The protection net for the manual pile digging operation is characterized by taking the shape of a cambered surface; the height H of the cambered surface is larger than 1/3 of the diameter of a pile foundation hole, and smaller than 1/2 of the diameter of the pile foundation hole; the peripheral outer frame of the protection net is made of angle iron; the surface of the protection net is a steel net; and the steel net is supported by twisted steel. The semi-diameter of the protection net can be defined according to the size of the pile foundation hole, so as to solve the problems that the protection net cannot achieve the safety protection function when the semi-diameter of the protection net is too small and a slag ladle cannot be lifted easily when the semi-diameter of the protection net is too large.
