603.01 Description
This work consists of placing steel jetty bank protection. This consists of a mainline jetty with or without back -up jetties as shown on the Plans. The jetties consist of steel jacks connected by steel cables or reinforcing bars to a deadman anchor. The Department will establish the length of mainline and back up jetties and the distance be tween lines of jetties as shown on the Plans. The Resident Engineer may direct changes to the lengths and locations of jetties, if erosive conditions have altered the landscape and rendered the Plan design ineffective.
603.02 Materials
A.Steel Jack Provide steel jacks consisting of the following: Three new structural steel angles, 4 in × 4 in × ¼ in × 192 in [100 mm × 100 mm × 6 mm × 4,800 mm]; Six high strength bolts with hexagon heads and nuts, ½ in × 1½ in [13 mm × 38 mm]; and No. 6 double -anneale d smooth -wire lacing.
B.Steel Cable Provide used -steel oil -field cable that has been, inspected, respooled, and oil -treated. Ensure the steel cable has a diameter of at least ⅞ in [22.2 mm], or provide reinforcing steel bars of at least ¾ in [19 mm] in d iameter and cable clamps for fastening. STEEL JETTY BANK PRO TECTION 603.05 541 C. Deadman Provide deadman of concrete or timber. Ensure the concrete deadmen are Class A Concrete at least 3 ft × 2 ft × 1½ ft [0.9 m × 0.6 m × 0.5 m]. Ensure the timber deadmen are new creosoted railroad ties at least 6 in × 8 in × 96 in [152 mm × 203 mm × 2,400 mm], or creosoted timber pile cutoffs with a diameter of at least 7 in [178 mm] at the smallest end and a length of 8 ft [2.40 m].

603.04 Construction Methods
A.Constructing Jack s Bolt three steel angles together so each angle is perpendicular to the other two angles. Construct the jacks to a height of at least 9 ft [2.7 m], and lace with at least four wire lines as follows: Tie the outside lacing line at each angle. Pass the sec ond lacing line through the angles 2 ft [0.6 m] from the ends. Pass the third lacing line through the angles 4 ft [1.2 m] from the ends. Pass the inside lacing line through the angles 6 ft [1.8 m] from the ends.
B.Anchoring Jacks Use double runs of steel cable or reinforcing bars to anchor the jacks. Pass one cable or bar on each side of the jack and apply a cable clamp to hold the cables together and to keep the jack in place. For a mainline jetty, anchor the cables or bars at each end with a deadman. For backup jetties, fasten the cables or bars to the mainline at a steel jack and anchor to a deadman at the opposite end. Minimize the use of splices and, if necessary, place splices only at a jack. Make splices, construct end connections to timber deadme n, or connect backup jetties to a mainline jetty by wrapping each steel cable around the jack or deadman at least twice and fasten with double cable clamps. Connect concrete deadmen as shown on the Plans. Splice reinforcing bars with a double -flare v -groove weld of at least 3 in [75 mm] in accordance with the current edition of the AWS “Reinforcing Steel Welding Code .”
C.Placing the Deadman Place the deadman in a trench and ensure the pull is at right angles to the deadman. Ensure the deadman bears on u ndisturbed earth. Bury the deadmen at least 6 ft [1.8 m] deep, measured to the bottom of the deadman. Backfill the trench and compact the soil to the density of adjacent in -situ soil.
603.05 Method of Measuremen T
The Resident Engineer will measure the st eel jacks by the number of jacks constructed, placed, and anchored. For the mainline jetty, the Resident Engineer will measure the length of steel cable from the center of the steel jack to the center of the deadman. For backup jetties, the Resident Engin eer will measure the length of steel cable from the tie to the mainline jetty to the center of the deadman.
