Introduction

Walter Strever is a notable inventor based in Cromwell, Connecticut, who has made significant contributions to the field of concrete pipe manufacturing. With a total of two patents to his name, he has developed innovative methods and apparatuses that enhance the efficiency and quality of concrete pipe production.

Latest Patents

Strever's latest patents focus on an apparatus for making concrete pipe. This invention specifically addresses the vibration treatment of concrete pipe for compaction and residual stress relief. The process involves forming a concrete pipe within an external jacket using a rotary packerhead method. The jacket is positioned vertically, and the packerhead is moved progressively upward within the jacket, rotating and distributing the mix radially outward while troweling the internal surface of the pipe under formation. Upon completion, the green pipe is removed from the machine and transported to a hollow, vertically split, radially expandable and contractable cylinder. The pipe is lowered around the cylinder, which is then expanded to engage the internal surface of the pipe. A vibrating mechanism within the cylinder is activated to vibrate the pipe throughout its length, ensuring optimal compaction. The pipe is then returned to the machine for a finishing pass, where any voids are filled, and the pipe is subsequently cured.
