摘要
以在建怀化—邵阳—衡阳铁路苍稼岭特长大断面强涌水隧道施工为背景,依据工程水文地质条件,结合施工方案及其涌水量预测结果,提出了长距离反坡排水总体方案,计算得到了排水高差、泵站级数、抽水机数量、集水井容量等排水参数,确定了设备型号及排水管配置。实践表明,按照提出的排水方案、排水参数及选定的设备施工可以达到较好的排水效果。
Taking the project construction of super long and large section tunnel with strong water gushing in Cang jialing of Huai Shao Heng railway under construction as background,the scheme of long distance reverse slope drainage was put forward by relying on the hydrogeological conditions of the project and combining with the construction scheme and the prediction results of the water gushing,the drainage parameters including drainage height difference,pumping station series,number of pumps and collecting well capacity were calculated,and the equipment type and drainpipe configuration were determined. Practice shows that good drainage effect can be achieved according to the proposed drainage scheme,drainage parameters and selected equipment.
