用於測量土釘力學性能的抗撥力測試箱

One kind of soil nail pullout test box, comprising: a test box body, the left and right sides (ie soil nails tail and front) were provided with a convex body connected to pass this test case of a first chamber and an additional second additional chamber, the test box body and said first additional sample chamber is filled with soil; soil nails to be tested is provided in the test chamber body; an upper cover plate removably connected to the box body of the test the upper end of the box body for closing the test;-rubber water bag, provided on the upper surface and the lower cover of the upper surface of the soil samples, soil samples for the pressure applied to the vertical direction; pull pulling force applying means disposed in the main body of the test chamber on one side of the second additional chamber, the pulling force is applied to the soil nailing device and the other end connected to a pulling for the soil nail pullout; when the test box work, the measure applied to the soil nail pullout force and the soil nail pullout force of the displacement can be tested to get the soil nail pullout resistance ability.
