ABSTRACT:
Process and apparatus for the construction of improved tank structures employing a pump metering and delivery system which accurately meters, mixes and evenly sprays composite materials to form the walls of tanks or containment vessels. Such systems have specific application to the construction of walls of prestressed tanks formed by inflating a membrane and applying rigidifying material outwardly of said membrane and then prestressing the walls by circumferentially wrapping prestressing material around the same. Promoters, catalyst, and other chemicals are used to create composite walls, each feeding into individual pump systems comprised of at least two hydraulic cylinders connected to supply cylinders which are coordinated so that their strokes are controlled to arrive at a desired flow. The flow is then channeled through a mixer which mixes the material for spraying through a nozzle. The flow from the nozzle can also be intermixed with chopped glass from a chopper system or with granular materials. Both the glass chopper system or the granular material feed system and the movement of the hydraulic system is controlled by servo units which can be controlled to the desired volume of spray. The spray unit is moveably located on the tower which can ride around the tank as well as position itself vertically allowing for the continous spraying of the walls of the tank. A computer can be used to synchronize the pumping rates, the chopper rates and for other considerations. The computer can also be used to monitor and store the output of the system.
