I do try to check the Brew Cabin every day, but sometimes it's just not possible for all of the reasons Bob mentions and a whole host more!
Brick rubble will do nothing but make matters worse. You need to get the sub-base to dry out.
A properly constructed sub-base will rid itself of excess water, either by draining to ground (assuming the sub-grade is suitably permeable), or via buried land-drainage which provides an escape route from the sub-base to some suitable outfall point for those times when conditions are bad. Once the paving is in place, far less surface water will find its way into the sub-base, so it becomes much less of a problem.
For now, find the lowest point within the sub-base area and dig a sump, which is essentially a deepr hole where all the excess water will collect. From that you either bale out or pump out the excess and get rid. It usually needs around 24-48 hrs without heavy rain for a sodden sub-base to drain and firm-up sufficiently to allow paving to be installed.
