Escape rod

Abstract

This article is a pile core position confirmation escape rod (pile core escape rod with level) for confirming whether or not a confirmed member (for example, a drilling rod or a pile) is positioned at the correct pile core position relative to the pile core in order to prevent pile core misalignment. As shown in the "Reference Diagram Showing the Names of Each Part," this article is equipped with a vertically elongated rod-shaped portion whose lower end is driven into the ground, a disk-shaped portion provided at the upper end of the rod-shaped portion and struck with a tool such as a hammer when driving the rod-shaped portion into the ground, a level provided near the upper end of the rod-shaped portion for confirming whether or not the rod-shaped portion driven into the ground is tilted, and left and right handles provided near the upper end of the rod-shaped portion for a worker to hold with both hands when pulling the rod-shaped portion out of the ground. As shown in "Reference Diagrams 1 and 2 showing the outline of the use state," this product is installed vertically by driving the lower end of the rod into the ground at two positions perpendicular to the pile core, and then the worker can check whether the member to be checked (for example, a drilling rod or pile) is located at the correct pile core position relative to the pile core by aligning the markings on the measuring rod with the installed product (relief pile). Furthermore, after this check, when the worker pulls the rod of this product out of the ground, he can firmly grasp the left and right handles with both hands and apply a lateral rotation force, making it possible to easily pull the rod out of the ground while preventing it from bending.
