Whentesting a batter pile, reaction piles shall be battered in the samedirection and angle as the test pile; the test beam s shall beperpendicular to the direction of batter. If two or more reactionpiles are used at each end of the test beam sthey shall becapped with a suitable steel beam s set on steel bearing platesor directly on and welded to steel reaction piles Fig.
Support the ends of the test beam s withreaction piles or cribbing. Bearing plates shall beset perpendicular to the longitudinal axis of the pile. Notes and illustrations includedherein are explanatory or advisory. The occurrence of suchhorizontal movements, and the necessary reactions to resist such move-ments if they are to be prohibited, should be considered when designingand constructing the load apparatus for the group test.
We are nonprofit website to share and download documents. N OTE 2—Use same type reaction piles or cribbing at both ends of test 3d689-90. While the procedures herein produce a relationship between appliedload and pile movement, the results may not represent long-term performance. This test method isdivided into the following sections: N OTE 4—Unless the hydraulic jack pump is attended at all times, it isrecommended that the jacking system be equipped with an automaticregulator to hold the load constant as pile movement occurs.

N OTE 3—Plate not required for steel reaction pile. If two or more jacksare to be used to apply the test load, they shall be of the sameram diameter, connected to a common manifold and pressuregage, and operated by a single hydraulic pump.
We are always happy to assist you. If two or more reaction piles are usedat each end of the test beam sthey shall be capped with asuitable steel beam s set on the piles or on bearing plates Fig. This test method is applicable to alldeep foundation units that function in a manner similar to piles,regardless of their method of installation.
The hydraulic jack s shall be calibrated over its complete range of ram travel forincreasing and decreasing applied loads. Current edition approved May 25, Asuperscript epsilon e indicates an editorial change since the last revision or reapproval. The method in 4. Bearing plates on cribbing shall be set in a horizontalplane. N OTE 5—Considerations should be given to employing a dual load-measuring system pressure gage and load cell to provide as a check andas a backup in case one system malfunctions.
