根据现场实际状况设计、实施了更换柱子和基础施工方案,在不停产的前提下,通过抱箍(槽钢)、钢托架和千斤顶组成的组合支撑顶升系统相结合,成功地把原有矿石输送栈桥中的十棵柱子基底标高(绝对高程),由原来的1870.50m,降至到1867.50m,其中一棵柱子基底标高(绝对高程),由原来的1870.50m降至到1866.00m,从而解决了55m长的矿石输送栈桥,因新建项目场地标高(绝对高程)调整降低,导制基础悬空的问题。为建设单位节约原有矿石输送栈桥改道费和设备拆除后再重新安装等费用约300万元,并保证了厂方正常进行矿石输送的生产需要,取得了较好的社会效益和经济效益。
According to the actual situation of the site design and implementation of the replacement of pillars and basic construction program, without stopping production under the premise of the hoop (channel), steel brackets and jack composed of a combination of support lifting system, the successful combination of the original The elevation (absolute elevation) of the ten pillars in the ore conveying trestle dropped from 1870.50m to 1867.50m, and the height of one pillar base (absolute elevation) dropped from 1870.50m to 1866.00m The 55m long ore handling bridge was solved, and the adjustment of the elevation (absolute elevation) of the new project site was reduced to lead to the problem of dangling the foundation. For the construction unit to save the original ore transport trestle diversion costs and equipment removal and then reinstall the cost of about 3000000 yuan, and ensure the normal production of ore ore production needs, and achieved good social and economic benefits.
