摘要： 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.
