Precast concrete wall with elevated roadway and method for constructing wall

Abstract

A precast concrete wall on a prepared subgrade, comprises standardized, precast, reinforced concrete foundation, wall and cap modules. The cap modules include parapets on opposed sides and an elevated roadway therebetween. A plurality of tie down rods, each extending through the cap modules, two or more courses of wall modules and at least partially into the foundation modules. An optional anti-tunneling barrier is provided in the subgrade, below the foundation. A method of constructing the wall includes specifying standardized reinforced concrete foundation, wall and cap modules so that they can be manufactured by multiple suppliers, and providing a logistical model to minimize shipping costs by matching each point of fabrication with the appropriate point of delivery.

Description

PRIORITY[0001]Priority is claimed to U.S. provisional patent application Ser. No. 62 / 480,908 filed Apr. 3, 2017, which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present disclosure relates to precast concrete wall structures and methods for constructing the same.BACKGROUND OF THE INVENTION[0003]Many existing wall structures can be readily circumvented by scaling over or tunneling under the wall, or by breaching or bypassing the wall. Some wall structures are unsuitable for rugged or remote sites. Others are prohibitively expensive to construct, or require specialized materials or highly skilled labor. Further existing wall structures frequently suffer from poor aesthetics. Finally, some wall structures require significant and costly maintenance. For these reasons, there is a recognized, but as yet unfulfilled need, for a wall structure that provides an effective barrier to the movement of people, animals and / or prohibited substances such as n...

AI Technical Summary

Benefits of technology

The present invention is a new method for creating walls using precast reinforced concrete modules that can be efficiently transported and fabricated at multiple locations. The use of elevated roadways and pre-sized units reduces the need for expensive access roads and allows for the removal of brush or trees adjacent to the wall. This method can provide a cost-effective and efficient barrier to the movement of people, animals, and prohibited substances. The size of the wall can vary depending on the location and purpose. Overall, this invention provides a new way to construct secure and efficient walls in difficult or remote locations.

Problems solved by technology

The dust raised by patrol vehicles on unpaved roads is a maintenance issue and signals the location of patrol agents.
