Not having the Riverton module handy, but doesn't the bolt hole description mention a light dry sand being used?

Think of a wood burning fireplace with the doors shut and the flue shut. The chimney above is the emergency exit filled with sand and gravel, held in the chimney above by the flue.
Open the exit hatch. Where the bottom of the floor should be, is now a pit (open pit) that has been built and calculated to hold exactly the amount of sand and gravel in the exit shaft above (this doesn't need to be a straight down pit, but could also be a void to either side that the sand and gravel will fill up). Reach up release the hatch holding the sand and gravel up, it now falls down from the exit shaft above into the pit. The pit is now filled up, you can now either stand or crawl in (taking your shovel with you) without much trouble and climb your way up shaft and break thru the last few feet of earth above the exit.
No need for digging your way out in a few hours, figuring out how to open the exit hatch (since it will now also have the weight of the sand and gavel in the shaft pressing on it from the inside). No fuss no muss.
