18、 4 Introduction A raingauge pit consists of a pit, normally square in plan and up to a maximum of about 1 m in depth, and a grating, normally of galvanised sheet steel or plastic. Such a pit can contain any suitable type of raingauge. The pit gauge may be used in its own right for improved measureme
19、nt of rainfall or for comparison purposes against other reference raingauges. 1 Scope This European Standard specifies the design of a reference raingauge pit. The specified details of the pit and the grating, are purposely kept to a minimum in order to allow each raingauge operator latitude in thei
20、r construction and to suit local conditions. 2 Design and construction of the reference raingauge pit Figures 1 - 3 show the design of the pit, including the required dimensions of the pit and the grating, and the method of installation of the raingauge. The specified dimensions are not critical, bu
21、t shall be used whenever possible. Variations are acceptable within the indicated tolerances. The pit shall preferably be sited on level ground to avoid possible surface runoff into it during prolonged heavy rain. However, in mountainous areas, this may not be possible or desirable and adequate drai
22、nage shall be provided in such cases. The sides of the pit shall be formed of brick, concrete, corrugated iron, plastic, preserved wood or other suitable material. They shall be supported to prevent collapse. Supports shall be provided around the edges, or at the corners of the pit, on which to rest
