Sheet pile can sometimes be used effectively to anchor GU 6N or GU 7N or GU 7S walls. Piles must be driven to their final depth within 2 hours of hitting ground water or any water. Since 1997, in partnership with the Laboratoire Central des Ponts et Chaussées in Strasbourg, ARCELOR GU 6N has been carrying out a vast study to qualify the improvements jetting can GU6N make to vibratory driving of steel sheet piles, and to understand its effect on the surrounding ground and on the sheet piles themselves. Brushing with a little soapy water just prior to GU7N driving may help the interlocks slide together easier.

If only two steel sheet piles form each frame, it is necessary to connect GU 8N and GU 8S the frames with a continuous reinforced concrete cap. The anchor rods can then be attached to the concrete cap. Containers for pouring A-30 into interlock ( Coffee cans, plastic containers or dispensers work the best) * Insulating foam, backer rod, sealant or similar to seal ends of piles (see photo for example) The process basically involves GU 7N discharging a fluid (mostly water, sometimes in association with air) at controlled GU7S pressure and/or flow rate near the toe of the sheet pile being driven. Plastic buckets approximately 4 gallon size for mixing. The steel jetting pipes are attached to the sheet pile and are connected to the pumps by hoses. Measuring bucket marked at 7.5 quarts (1/2 of the resin - or appropriate measure for quantity needed).However, if three GU8S piles are used, each frame can support a tie rod through the center pile and act independently.

The pile angled toward the GU8N wall will be in compression while the pile or piles angled away from the wall will be in tension. Measuring GU8N container marked at 0.5 quarts (1/2 of the hardener - or appropriate measure for quantity needed).) * Drill and mixing GU 7S paddle The jet of fluid loosens the soil, thus reducing the resistance at the toe of the sheet pile during driving. Depending on ground conditions, the fluid GU 8S that flows along the pile can reduce skin friction. Tool for checking depth of A-30 in the interlock.

The resulting GU6N and GU7N forces are easily determined from a force polygon. Jetting is combined with a sheet pile driving process, usually vibratory driving but sometimes jacking. Disposable paint stirring sticks to scrape remaining resin into mixing container It generally speeds up GU 8N pile installation and reduces induced vibration, without damaging the piles. GU7S shows the jets emerging from the pipes at the pile toe. It was taken during a test of jet operation, prior to driving.

This method of support can be used effectively only if the brace piles can be adequately seated in a underlying stratum of soil or, preferably, rock. wall through wales may also be used as anchors. Suitable gloves GU 8N and clothes (A-30 is difficult to remove from clothing) Since 1997, ARCELOR, in partnership with the Laboratoire GU7N Central des Ponts et Chaussées and the Laboratoire Régional des Ponts et Chaussées de Strasbourg, has been carrying out a vast study to qualify and quantify the improvement jetting can make to vibratory driving of sheet piles and understand its effect on the surrounding soil. Driving Apply in the socket. IMPORTANT - Must GU8S have correct amount in the interlock. Under some ground conditions, the water flowing along the pile acts as a lubricant and could reduce skin friction. Jetting enables GU 7S sheet piles to be successfully driven into dense soils.

The reaction is developed GU7S and GU8N and GU8S through friction and/or adhesion between the pile and the soil behind the wall. Carpenters level for checking level of pile (should be fairly long level)The process basically involves discharging water under pressure near the toe of the sheet pile being driven. Only the length of GU 7N pile outside the active failure zone should be considered effective in mobilizing resistance. The actual capacity of the H-piles should be checked by pull out GU 8S tests in the field. More is not always better! The most efficient amount in the side interlock of paired piles is about 1/8" . The rigid steel jetting pipes are usually welded to the pile, with hoses connecting them to the jetting pumps. The tension ties should be prestressed to a percentage of the GU6N computed anchor pull by jacking against the wall before making the final connection. The water jet loosens the soil, reducing the resistance to penetration of the GU 6N pile toe during driving. Particular attention should be given to the connection details at the wale since this may be subject to rotational stresses.
