本発明は地盤の強さを地盤載荷試験方法の中の反力式載
荷法で行う際に使用する羽根付アンカー装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a bladed anchor device used when testing the strength of the ground using a reaction loading method among ground loading testing methods.
（従来の技術）
従来、地盤の強さを測定する方法としては神々の方法が

変位との関係から地盤の強さを知るだめに行う試験方法
である。(Prior Art) Conventionally, there are divine methods to measure the strength of the ground, among which the Dutch method, Swedish method, flat plate loading method, etc. are frequently used as static loading methods. This involves applying a load at the original location of the ground, and applying the load, time, and
This test method is used to determine the strength of the ground based on its relationship with displacement.
この試験方法の中で載荷試験法に２通りあり、実載荷法
と反力式載荷法とがある。本発明はこの中の反力式載荷
法に使用するためのものである。Among these test methods, there are two types of loading test methods: an actual loading method and a reaction loading method. The present invention is for use in the reaction force loading method.

The upper part is supported by a support member 3 such as channel steel, H type 1i, etc., and a double pull-out pile 2
A loading plate 4 is installed on a relatively flat ground between the support material 3 and the loading plate 4, and a shaft 5 is placed on it, and pressure is applied between the support material 3 and the loading plate 4 to reduce the resistance when the pull-out piles 2 and 2' are pulled out. Use force to apply a load to the loading plate. Amount of settling of the loading plate at that time, time,
It measures the strength of the ground based on the load. However, this method 't:, T, "C2, ----A/-f...I (Installation of pull-out piles 1'1" by ll) takes time and may be difficult depending on the quality.・) Is there a drawback?
7. We provide an anchor device that allows easy embedding of pull-out piles and easy removal after testing and testing.

It's great. A rod/blade engaging portion 8 such as a hexagonal nut is attached to the top and bottom of the tip of the rod 7, and a blade 9 serves as a receptacle for this mouth. One force of the rod/vane engaging part 8 engages with the screw cut in the opening and the door, and as the rod 7 rotates, the ground falls in the direction of arrow a, and the vane 9
As the blade engaging portion 8 moves, it opens and closes in the direction of the arrow. In addition, (a) shows the blade 9 in the open/closed state, (Q)) shows the closed state, (c) shows the steel pipe section 6 with the opening 10, and (d) shows the blade 9 in the closed state. 9τ I heard it in three directions (
