dewatering unit meaning in English

脱水剂

In this paper , mainly based on arranging data with well pumping tests in dam foundation and sum up the laws of flows under the condition of deep well pumping , the useful dewatering calculation model and parameters were set up . secondly , based on the well constructing technique which was discovered under the condition of in - situ bumping test and calculating the dewatering scheme of the two dewatering units with the calculation model , the final dewatering scheme was put forward . at last , the final dewatering scheme was appraised by observation during the construction , and it satisfied with the construction request
本文主要通过坝基现场抽水试验试验资料整理，在揭示黄土坝基降水特性规律的基础上，确定可以反映现场抽水条件的的实用降水计算模型和参数；再根据现场抽水条件试验开发的成井技术和计算模型计算坝基和坝肩两个水文地质单元的降水井方案，并按工程类比法确定最终的降水方案；最后，通过施工过程中的观测情况对降水方案进行评价，降水方案能够很好地满足施工的要求。
