Significance and Use

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.

Scope

1.1 This test method is a performance test, which measures the effectiveness of vertical strip drains on the time rates of consolidation of compressible soils from construction project sites.

1.1.1 It is expected that the design agency will be responsible for performing this test. It is not intended to be a manufacturer performed test.

1.2 This test method is applicable to all vertical strip drains.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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