中文摘要:
      介绍了在水位较高、降水困难的垃圾填埋区进行暗挖区间泵房施工技术。通过合理改迁泵房位置,运用深孔注浆进行加固,并在开挖过程中采取有效安全措施,顺利完成了泵房的施工。竖井周边地面沉降监测数据稳定,主体施工过程中竖井井壁沉降、裂缝、收敛变形均在容许范围内,废水泵房主体施工安全可控,符合设计规范要求,整体效果良好。
英文摘要:
      Introduced in the present paper is the construction of a pumping house in a mining refuse landfill section where the water level is relatively high and it is hard to dewater. In such a case, the location of the pumping house is reasonably changed, the measure of deep hole grouting reinforcement is used, and effective safety measures are taken in the excavation process, owing to all of which the construction of the pumping house is successfully completed. The monitored data of ground subsidence around the shaft is found to be stable, the settlement, cracks and convergence deformation of the shaft wall are also found to be within the allowable range during the main construction process, and the construction of the main body of the waste water pumping house is found to be safe and controllable, all of which are found to be able to meet the requirements of the design specifications, and thus, the overall effect is good.
