Значение и использование

5.1 As this is a time intensive test, it should not be considered as an acceptance test for commercial shipments of prefabricated vertical strip drains.

5.2 Prior to the development of vertical strip drains, when it was desired to increase the rate of consolidation of a compressible soil on a construction project, large diameter sand drains were installed. Vertical strip drains can be installed in areas where it is desired to increase the rate of soils consolidation in place of these large diameter sand drains.

5.3 This test method can be used to compare the performance of vertical strip drains to that of sand drains.

Область применения

1.1 This test method is a performancetest, which measures the effectiveness of vertical strip drains onthe time rates of consolidation of compressible soils fromconstruction project sites.

1.1.1 It is expected that the designagency will be responsible for performing this test. It is notintended to be a manufacturer performed test.

1.2 This test method is applicable toall vertical strip drains.

1.3 The values stated in either SIunits or inch-pound units are to be regarded separately asstandard. The values stated in each system may not be exactequivalents; therefore, each system shall be used independently ofthe other. Combining values from the two systems may result innon-conformance with the standard.

1.4 This standard does not purportto address all of the safety concerns, if any, associated with itsuse. It is the responsibility of the user of this standard toestablish appropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.
