WALL TRENCH PANEL AND SYSTEM

Abstract

A wall trench panel and system utilizes extruded aluminum panels having ribs and a socket edge and a ball edge which allows them to slide together and create a continuous trench wall that may be stabilized using traditional jack and wale techniques. To allow the trench to make a corner, a knuckle is provided which accepts both ball and socket edges of the panels to change the direction of the panels. In deep trench situations, panels of different sizes are provide to stager the installation of the panels which provides a continuous trench wall that is very strong and stable which eliminates the necessity of staging the trench in ever smaller portions.

DETAILED DESCRIPTION OF THE INVENTION

[0018] In the following detailed description of the invention, reference is made to the drawings in which reference numerals refer to like elements, and which are intended to show by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and that structural changes may be made without departing from the scope and spirit of the invention.

[0019] Referring to figures, a trench wall panel and system 100 is shown having an extruded shoring panel 110 which has a socket 120 along one outer edge and a ball 125 along an opposing end. Each shoring panel 110 slides into a corresponding end to form a continuous wall of shoring panels 110 to support the earth 150 to form a trench 170 lined with shoring panels 110. A plurality of ribs 115 are used to provide structural stability and rigidity to shoring panel 110. Of course, although shoring panel 110 is shown with two ribs 115, any number of ribs 115 may be used. In addition to providing additional strength to shoring panel 110, ribs 115 also act as a guide for construction supports when using a wooden framework for support.

[0020] In use, any number of shoring panels 110 may be used to provide a trench wall of a desired length as needed. In a use where it is necessary to form a corner, a knuckle 130 is provided to join two shoring panels 110 to form a corner. Knuckle 130 has a pair of knuckle sockets 135 along opposing edges and a pair of knuckle balls 140 at 900 which allows corresponding joining portions (socket 120 and ball 125) of shore panels 110 to join at an angle to form the corner. Both shoring panels 110 and knuckles 130 are made of extruded aluminum to provide high strength and light weight. Of course other materials may be used such as, but not limited to, sheet metal, zinc coated metal, etc. or even composite materials as long as the material can be formed with the ribs and connecting structures.

[0021] Now referring to FIG. 8, a top view of shoring panels 110 being placed to follow an irregular trench boundary. This is particularly important in an emergency situation where you need to stabilize a trench collapse to reach and rescue trapped individuals where it may not be possible to carefully place the trench panels.

[0022] Referring now to FIG. 9, a top view of trench wall panel and system 100 is shown forming a completely bounded area by using the selected panels and knuckles to form the boundary desired. This may be used in situation where water is an issue. Although shown as a square installation, other configurations are possible using the appropriate number of panels and knuckles as needed.

[0023] FIGS. 10 and 11 show a typical trenching operation using shoring panels 110 and braced with jacks 160 and wales 165. The braces may be wood or may be hydraulic jacks depending on the situation encountered and the available resources of the user. In hydric soils, sand, gravel, etc. anything that is somewhat loose or granular, the soil is continually leaking through into the trench delaying rescue and also changing the dynamics of the soil pressures outside the trench and making a secondary collapse more likely. Closed wall trench panel and system 100 prevents the majority of leaking while adding structural strength and unitizes trench 170. It also speeds up the process of installing trench panels as they simply slide together. You simple place the first panel, stabilize it and then build from there. While prior art methods are adequate under perfect conditions, in real life situations, especially under time critical emergency conditions, closed wall trench panel and system 100 provides a system that works in imperfect real life conditions such as where the trench is curved or sloughed off in an irregular manner.

[0024] Referring now to FIG. 12, a staggered trench wall is shown using two different size panels 110, and 112. In this way, a very tall wall may be constructed without having to use the inverted layer cake method shown in FIG. 11. This is particularly important in emergency situations where having to construct different layers can significantly increase the time taken to construct. The instant method of staggering the size of the panels to provide deep trenches is significantly faster to construct and stabilize the trench. Although two different size panels are shown, other combinations of varying size panels may be used.

[0025] Although the instant invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.
