地震水化观测点的引水装置研究

STUDY OF DIVERSION DEVICES AT SEISMO-HYDROCHEMICAL STATION

本文分析了水化观测点引水装置中的四个重要环节,即动水压力与取样位置的关系;取样深度问题;管道局部阻力及主、支管相对位置;流量控制问题。并根据我国地震水文地球化学观测网的现状,提出了自流井引水装置的分类原则及泉眼改造原则。剖析了四种有典型意义的自流井引水装置类型。最后就引水装置的综合评价问题进行了讨论。

Four key links in the diversion devices at seismo-hydrochemical stations: the relation between hydrodynamic pressure and sampling position, the problem of sampling depth, the partial resistance of pipeline and the relative position between the main pine and brance pipe, and the control of the outflow have been investigated. In terms of the current status of the seis-mo-hydrogeochemical observation network in China, the principles of classification of drawing device at the artesian well and reformation of spring eyes are proposed. Four kinds of typical drawing devices of artesian well are analyzed. Finally, the problem of synthetic evalu-tion on the drawing device is discussed.
