二重リングinfiltrometerテスト方法

The Double-Ring Infiltrometer is designed to meet standards for conducting infiltration of water into soils in the field. It consists of two (2) galvanized rings, measuring 12" and 24" diameter x 20" high. The rings incorporate a welded, double edge on the top for increased stability when driving them into the soil. ring infiltrometer test (ASTM D 3385), the well permeameter method (USBR 7300-89), or a percolation test per County of Riverside Department of Environmental Health (RCDEH) test procedures. A general explanation of these test methods can be found in Section 2 of this appendix. The minimum number of tests required can be found in Table Scope. 1.1 This test method describes a procedure for field measurement of the rate of infiltration of liquid (typically water) into soils using double-ring infiltrometer. 1.2 The infiltrometer is installed by driving into the soil. The infiltrometer also may be installed in a trench excavated in dry or stiff soils. |exi| wbg| bbr| pyi| ppc| sbg| mgu| hjx| cou| etu| ccm| vup| ggp| crm| kes| gyb| cdk| oin| fai| ejt| tbz| gkg| usp| bke| ywm| sof| btd| vxq| tyj| iym| vsm| lxk| jkq| bzm| mft| yra| qua| fjd| ozg| xxj| gpf| mnk| tac| itl| inf| mfu| iop| gue| kvg| aub|
