摘　　要：在施工异形及圆柱形立井过程中,对立井的浇筑支护所用模板井圈进行了设计,通过设计的新型井圈,解决了异形及圆柱形立井浇筑成型问题,同时也降低了立井井圈的成本,并且可循环使用,提高了经济效益。该井圈的质量、大小都优于传统槽钢井圈,减少了工人的劳动强度,降低了运输抬运大型井圈的安全风险。In the construction of special-shaped and cylindrical vertical shafts, the template wells used in the cementing support of the vertical shafts were designed. The new wells crib is designed to solve the problem during casting and forming of the special-shaped or cylindrical vertical shafts. The cost of the engineering decreased and the crib can also be reduced, economic benefit improved. The quality and size of the well cribs is superior compared to the traditional one, which reduces the labor intensity and reduces the safety risk for transportation.
