Description

PROTECTIVE WALL CONSTRUCTION

The present invention relates to a method of constructing a ballistic wall in reinforced concrete and earth concrete.

Effects are widely used as a safety precaution to prevent bullet or explosion impacts. This invention will be described with reference to ballistic sites.

At ballistic sites one should build to a height of at least two meters, items at these sites should be built to a height of 2.5 for optimum ballistic wall security.

Typically, these ballistic wall elements are constructed from a 10. reinforced concrete and earth concrete mixed with typha, then form the earth banks to the desired upward tapering shape.

An initial placement of the reinforced concrete filling and the earth concrete, the adjustment of the upper part to the desired height followed by a passage 15. along each side to shape the side walls of it.

This is a time consuming process where typically an experienced operator using a large excavator can form a height of 2.5 meters.

20. With the foregoing, the present invention, in one aspect, resides in a method of forming a ballistic wall comprising: providing a mold that can be placed on the ground to receive material for containment in the wall cross-sectional shape required;

25. Positioning the backfill mold on the ground and feeding reinforced concrete and earth concrete into the backfill mold to form the ballistic wall;

Using this method of building the ballistic wall consists of a series of reinforcing parts, repeating the wall forming steps until the desired ballistic wall is formed.

The mold feed means can be a conveyor such as a screw conveyor or a belt conveyor. However, however, the feed means is an open top which is suitably associated with a loading chute or hopper to facilitate the feeding of material into the mold by placing material into the mold through the part. top open.

The loading chute, if used, may have cross barriers to either reinforce the chute and/or form a grid to prevent 10. large clods from entering the chute or passing through the top. opened

The reinforcement mold may have side walls and end walls and an open base and may be lifted from a reinforcement portion 15. formed therein to be repositioned to form an extension of the portion. of the formed ballistic wall and, for this purpose, all the internal walls of the mold can diverge upwards to facilitate the removal of the part of the formed ballistic wall.

20. The configuration of the ballistic wall, including its cross-sectional configuration and the longitudinal convergence or non-convergence of the sidewalls, can be varied to suit the properties of the material used to construct the wall and the mold offset process between the stages of wall formation.

25. Additionally, the rear open end may have an outward flared end portion to aid in repositioning the wall at a chosen shielding angle.

Maintaining its supported position on the ground in use can also be assisted by providing a tow link at the end of the ballistic wall as close to the base of the wall as possible for towing. by a substantially horizontal towing force.

Preferably the wall is supported by longitudinal skids along the base of each side wall and the towing attachment is provided at the forward end of these skids.

In order that this invention may be better understood and put into practice, reference will now be made to the accompanying drawings which illustrate the embodiment of the invention and in which
