Soldier PIles To Retain Water

[CWEngineer]

Initially we were going to use a Floodwall to retain water, but due to limited easment, we are planning to use another design to contain water.

I was looking at soldier piles with concrete laging, etc. to retain water.

I appreciate your advice on what reference I can use to design these solider piles with concrete laging and your suggestions.

THANKS

Soldier piles and lagging are usually considered to be a free-draining wall system. Water can leak under, around, and between the lagging boards or planks. Wrong application. Can you use interlocking steel or vinyl sheet piling?

 

[CWEngineer]

Yes, I belive interlocking steel or vinyl sheet piling can be used. Do you know where I can get information for that type of desing?

THANKS

Depending on your height you may want to look at a king pile system which is a solder pile system that uses interlocking steel sheeting. It is much stiffer than standard sheetpiles so it can cantilever higher. You can find info on this systemat

They refere to the system by their trade name Combiwall. Information on sheetpiles in general can be found at

I am looking at at wall to contain approximately 20 ft of water. Is this king pile system still applicable?

THANKS

gman1,

Try any of these sites. Also, almost any soil mechanics/geltechnical/foundation text books have information on sheet piling.

20 feet is a relatively high sheet pile wall to be cantilevered, with or without king piles, especially because you are supporting the base of the wall with buoyant soil which provides reduced passive resistance. This wall may need some type of support from tieback anchors or tie rods and deadman. What you are trying to design is more like a waterfront bulkhead than a channel wall.

As PE Inc. said 20 ft is very high for a cantilevered system. Depending on site conditions, you may be able to make it with the kingpile system. With out anchors, it is probably the only system that has a chance. I would call L.B. Foster and dicuss your site with an engineer. They can better advise you of the suitability of the product. Let us know how you make out.
