竖井施工前,要安装大,小20台左右的稳车,每台稳车有10至20个、深为0.8～1.2米须预留的地脚螺栓孔,过去一般采用1～1.5厘米厚的木板盒。混凝土施工完后,拆这木盒很费劲,拆出的木板基本上不能再用,消耗木材量较大。在凡口新副井施工中,我们利用了外管平滑的φ6英寸旧短钢管,加工成如附图所示的预留螺栓孔,施工了18台稳车基础,收到了施工方便、预留孔质量好和节约木材的良好效果。
Shaft before construction, to install large and small 20 or so steady vehicles, each having 10 to 20 cars steady, deep 0.8 to 1.2 meters to be reserved anchor bolt holes in the past generally used 1 to 1.5 cm thick Wooden box. After the concrete construction, demolition of the wooden box is very strenuous, basically can not be removed from the wood, consume large amount of wood. In the construction of the new auxiliary shaft in Fankou, we utilized the old φ6 "short steel tube with smooth outer tube and processed it into the reserved bolt holes as shown in the attached drawings. We constructed 18 sets of steady vehicle foundation and received the convenience of construction and reserved Well-quality holes and save the wood good results.
