groundwater drain信息详情
地下水排水管
drain───v.排水;流干;喝光;(感情)变淡;使精疲力竭;(非正式)将(球)轻击入穴;n.排水沟;下水道;负担;消耗;n.(Drain)(美、英、法、加)德兰(人名)
tub drain───排水管
brackish groundwater───微咸水
condensate drain───冷凝排水
flashboard drain───闸板排水管
drain plug───排污螺塞,放油塞
cogged drain───齿槽排水沟
drain on───排水管上
drain out───(使)流出; 流失; 失掉; 停止;排出;终止
The drain pipe jointing material of cement mortar with addition of water glass can effectively overcome the influence of groundwater and improve the quality of the joints.───在水泥砂浆中掺入水玻璃作为排水管的接口材料,能有效克服地下水影响,提高了接口工程质量。
In the meantime the time variation of the water level in the ditch has been taken into account, therefore the groundwater head are time-varying as the groundwater flows toward the drain system.───在讨论这个问题时,又考虑进了排水沟中的水位也是随时间而变化的,因此在地下水流动过程中的任一瞬时,其地下水头差也是一个变量。
decompress well and drainage ditch to drain and decompress can effectively reduce groundwater level and prevent immersion outside reservoir.───减压井和排渗沟联合排渗减压是降低地下水位、防止库外浸没的有效措施。
