Pull solution - think of guying a sapling. Do you have anything to use for stakes - lengths of rebar, tent stakes, etc, along with wire?
Push solution - wedge a piece of 2x4 between the head and the wall and then prop it up.
Drive a stake next to it so you can tie it off. This way you will puncture the water line, have to turn the water off, and you can safely cut off the offending pipe.
I just drove south from Burleson on I35 to Alvarado and back looking for someone to help. (10 miles)
One woman in a van was pulled over but some nice man in a white truck was already helping her. Traffic was avg 60mph but building. Gas is about 2.79 but the Citgo on Renfro and I35 has it for 2.64. The rest stops are busy but not full.
At I35 and Renfro the Lubys on the right going north is signing up evacs to send to areas shelters who have space. Pets will be kept at kennels. Electronic signs are in use to direct those wanting help to the Lubys.
If I were on 145 I would try to make it West to Waco or Hillsboro and come up I35 to Fort Worth.
(gas prices have rose here .20+ in 48 hrs)

I think I solved it before I read your solution, dirtboy, but I think I will add that to the mix. After I finish filling bathtubs, etc., I'm going to run out of further preps to do, so I might as well make the current ones even better.
