Very low cost, high performance, self-propelled, highway legal, shotcrete pump

摘要

The usefulness of an item or a process is largely a function of its cost. The perfect historical example of this is the cotton gin. This cheap machine so lowered the labor cost of removing the seeds from cotton fibers that cotton cloth became commonplace. This, among other things, helped fuel the industrial revolution. Likewise, the cost of building a home of concrete covered 3-d panels is out of the reach of most retired Americans in year 2002. The labor cost of applying concrete to these panels by trowels is prohibited. Also, the cost of using a Shotcrete system prices a 3-d panel home out of the reach of most retirees. This invention creates a Shotcrete pump for less than $2000. and can be built by any low skilled "weekend dabbler" using handtools. With this machine the house payment of a snug safe home costs $180 per month.
