一、前言农业、工业或生活用水,往往需从江河中提取。对于洪枯水位变幅较大的河道,通常采用在江河边兴建固定式圆筒形泵房。泵房高出一定机率的洪水位,以适应洪水涨落而泵站仍能正常运行。圆筒形泵房设计、施工和运行,已有多年历史。我区不少泵房为岩石基础,地质条件良好,岩石渗透性小。对于这种工程条件的泵房,我们从实践中感到值得研究改进,以达到节省工程量,方便施工,缩短工期,降低造价的目的。
I. Introduction Agricultural, industrial or domestic water is often extracted from the rivers. For the flood fluctuating large river, usually used in the river to build a fixed cylindrical pump house. The pumping station is above a certain level of flood level in order to adapt to flood fluctuations while the pumping station still operates normally. Cylindrical pump room design, construction and operation, has many years of history. Many pumping stations in our district are rocky foundations, with good geological conditions and small rock permeability. For the pump room of this kind of engineering condition, we feel that it is worth to study and improve in practice, in order to save the engineering quantity, facilitate the construction, shorten the construction period and reduce the cost.
