Method and Apparatus for Application of Mortar

Abstract

A spray head for spraying mortar is provided. The spray head includes a mortar supply pipe and a spinning head positioned at an outlet point of the mortar supply pipe, the spinning head directing mortar supplied from the mortar supply pipe in a direction substantially perpendicular to the direction of travel of mortar in the mortar supply pipe. An air intake for receiving air is further provided, the air being employed to spin the spinning head pneumatically. Finally, a material input port is provided for inputting material to be combined with the mortar in the mortar supply pipe at the outlet point of the mortar supply pipe.

AI Technical Summary

Benefits of technology

[0009]In yet another embodiment of the invention, a method for safely conveying, power, and supplying air, electric, raw rehabilitation material, water and other material to an application point through a specially designed harness that encapsulates and protects the components of such a delivery system may be provided.

[0010]In accordance with a further embodiment of the invention, an inventive centrifugal spinner is preferably provided that may allow for the introduction of high volume, high pressure air and / or other materials at a discharge point, which in turn allows the rehabilitation material to be projected or propelled at a high velocity. This high velocity material may be projected or propelled in a manner that achieves a high impact of the rehabilitation material on a desired surface, thus resulting in a desired packing of the material thereon. In turn, the rehabilitation material preferably achieves a high density at its point of application, positively affecting rehabilitation material (i.e. mortar) performance and durability. This durability and performance increase may include one or more of an improved resistance to chemical attack, an improvement of general imperviousness of the applied material, an improvement in the compressive strengths of the material, and achievement of a greater diameter placement.

Problems solved by technology

Application of mortar or other rehabilitation materials on the inside of concrete or metal pipes, other concrete or other surfaces to be remediated often takes too much time, the equipment is too expensive, and current processes fail to provide a satisfactory product.

Similar issues may present themselves when such pipe is formed of corrugated metal or other metal pipes, or any other pipe surface.

The issues may range from full structural failure, partial structural failure, cracks, exfiltration of materials from the pipe, infiltration of materials into the pipe, separation of joints, etc.

Such a system fails to provide a high velocity material discharge system, thus resulting in potentially uneven application of material,
