Shoring removal and compaction

Shoring removal and compaction

Shoring removal and compaction

(OP)
My roadway is being constructed in a fill embankment. Construction sequence is proposed to construct half width at a time. Temporary shoring is proposed to protect the embanked roadway (12' higher than existing). While doing the second half how would the required compaction at/near the shoring attained and how is that shoring pulled out? Do anyone share their experience?

Thanks

RE: Shoring removal and compaction

Why not just use some type of MSE wall?  It would be left in place when the other half of the fill is constructed.  

RE: Shoring removal and compaction

If you use the sheeting wall, backfill the way the specs require except for a few feet immediately behind the wall.  There, you should use walk behind compaction equipment and consider backfilling right behind the wall with an easily compacted material such as crushed stone.

You don't always need to remove soldier beams and lagging.  This type of sheeting is often abandoned in place, especially for jobs like this with staged construction.  If you use sheet piling, you probably will want to extract the sheets when the embankment fill on the front of the wall eventually reaches finished grade.
