(PAZ5360,PAZ 5370,PAZ5380,PAZ 5390)sheet piles

Sheet piles walls shall not be used where PAZ5360 utilities or highway PAZ5370 drainage must be located within the reinforced mass except that highway drainage may be placed within the reinforced PAZ 5390 soil mass if it runs vertically or perpendicular to the wall face. phase these deformations occur. In case that PAZ5360 occur during construction phase they can easily considered and compensated when the superstructure is placed. To be held at least once per quarter (weather permitting). This is to be confirmed to the team leader before lowering. In case that the deformations go along with the operation loads their magnitude may however be of paramount importance for the serviceability of the structure. Coxswain is to ensure a clear landing area below before PAZ5370 starting to lower the lifeboat. MSE walls shall not be used where floodplain erosion or scour may undermine the reinforced soil mass unless the PAZ 5380 wall is founded at sufficient depth or adequate scour protection is provided to prevent the erosion or scour. Only associate crew needs drill. No other persons shall be aboard the boat during the drill.

MSE walls shall not be used to support bridge abutments with shallow foundations nor pile supported bridge abutments where seismic displacements of the abutment would impose large forces on the PAZ 5370 wall face panels and the soil reinforcement to face PAZ5380 panel connections. Communications, visual/voice/radio, are to be maintained between the boat and the Team Leader at all times. Since steel sheet pile of this type never has been PAZ5380 or PAZ5390 build before, it was not possible to identify PAZ 5360 clearly the structure deformations to be expected during operation and over PAZ5390 lifetime. Once the lifeboat leaves the davits, only the coxswain will do anything to affect the lowering of the boat.

MSE walls may be used in front of PAZ 5360 supported bridge abutments where the seismic forces from the bridge superstructure are limited by elastomeric bearing pads supporting the bridge superstructure. This was the main reason why finally the PAZ 5360 specific proposal has been PAZ 5370 rejected by the awarding authority. There will be no exceptions to this policy, regardless of circumstance. Before securing from the PAZ5390 drill, the Team Leader will review and clearly indicate any additional actions to be taken. The classical design concepts of quay walls for large PAZ 5370 vessels with only one anchor placed close to the top and a free span down to the harbor bottom has reached dimensions which hardly allows for the ship dimensions needed for today traffic. Only the coxswain will order the release of the PAZ 5380 boat from the mooring lines and only when he is assured by visual means that he is waterborne. If it is realistic that the development of ships draught will increase in future as in the past, new concepts for the quay walls are needed urgently. These limited seismic PAZ5380 forces shall be considered in the design of the MSE wall. The drill will include the use of various equipment and shall be conducted in a realistic manner.

The design service life shall be increased to 75 years for MSE walls in front of pile supported bridge abutments. Open question PAZ 5380 remain however with respect to PAZ 5390 structural deformations during lifetime. To be held monthly to simulate recovery of injured personnel from various areas on the vessel. Before securing the drill, the Team Leader and First Aid/CPR PAZ 5390 person will review and clearly indicate any additional actions to be taken.

MSE walls shall not be used where aggressive environmental conditions exist unless environment specific PAZ5360 studies of the long-term corrosion or degradation of the soil reinforcement are conducted. A very promising one is multi-anchored combined sheet pile wall. The statical concept is well known PAZ5370 from deep excavation pits, the static stability of the ready build structure is relatively robust.
