Claims

[Scope of Claim for Utility Model Registration] 1. Guide rails erected at required intervals along both sides of an excavated groove so as to settle as soil is excavated and removed, and sliding between adjacent guide rails on both sides of the excavated groove. In an earth retaining device comprising a movably fitted earth retaining panel and a spindle serving as a cutting tension connecting guide rails facing each other in the groove width direction,
The guide rail includes a rectangular cylindrical core material and a pair of shallow groove-shaped outer frame members welded to both sides of the core material with lip portions facing each other in the groove width direction. The spindle is fitted into a lip groove-shaped guide groove formed by the lip portions of the pair of outer frame members and the outer surface of the core material, and the spindle is fitted and locked into a hole provided on the outer surface of the guide rail. Earth retaining device for excavated trenches. 2. Guide rails that are erected at required intervals along both sides of the excavated trench so that they settle as soil is excavated and removed from the trench, and earth retaining panels that are slidably fitted between the adjacent guide rails on both sides of the excavated trench. and a spindle as a cutting tension connecting guide rails facing each other in the groove width direction,
The spindle includes a spindle body and tip holders that are detachably attached to both ends of the spindle body, and each tip holder has a buffer on a surface that contacts the guide rail and is attached to the spindle body. The tip receiver body is inserted into the axial center of the tip receiver body from the guide rail side and connected by a wedge, and the retaining head at the tip is inserted into the vertical hole provided in the guide rail and rotated around the axis. An earth retaining device for an excavated trench, characterized in that it is provided with a retaining member that is latched to a guide rail.
