梁家矿风井净直径5.5m,井深260.5m,由大屯钻井队采用钻井法施工,悬浮下沉厚度为400mm的钢筋混凝土井壁,每节井壁长5m,两端预埋连接槽钢,节间采用螺栓连接。移交后由我处进行马头门及巷道施工,在进行提升设备及管路安装时,井筒内管路吊挂利用井壁间的槽钢,采用拉杆进行固定,实用效果良好。管路布置及固定方式见图1,图2。
The net shaft diameter of Liangjia Mine is 5.5m and its depth is 260.5m. Drilling by the Datun drilling team is carried out by drilling method. The reinforced concrete shaft wall with suspended thickness of 400mm is suspended. The length of each shaft wall is 5m long. , Internals bolted. After the handover, Maotoumen and roadway construction will be carried out by our office. During the installation of hoisting equipment and pipelines, the pipelines in the wellbore are suspended and utilized by the channel steel between the shaft linings, and the rod is used for fixing. The practical effect is good. Pipe layout and fixing method shown in Figure 1, Figure 2.
