Embodiment 1

[0028] In a typical embodiment of the present invention, such as figure 1 As shown, a transparent soil model test device for anchor plate drawing includes a soil filling model box, a soil retaining plate 6, an anchor rod 11, an anchor plate and a sealing plug, and its specific connection relationship is as follows: The side is the opening side, and the soil retaining plate 6 is slidably installed on the opening side of the soil filling model box, the anchor rod 11 passes through the soil retaining plate 6 and enters the soil filling model box, the anchor plate is installed in the soil filling model box inside the opening side, and the anchor The rods 11 pass through the anchor plates and the retaining plate 6 is provided with a plurality of openings 5 ​​which can be closed with sealing plugs.

[0029] More specifically, the soil filling model box is in the shape of a cuboid as a whole, and its four faces are respectively the bottom face, the front side 1, the rear side 4 and t...

Embodiment 2

[0037] In a typical implementation of the present invention, embodiment 2 discloses an anchor plate pull-out test system, including a kind of anchor plate pull-out test device based on transparent soil as described in embodiment 1, and also includes a laser generator Optical hardware equipment such as a laser generator and a camera, the laser emitted by the laser generator can enter the soil filling model box from the transparent surface of the filling model box, and the camera is arranged on the top surface and side of the filling model box to take pictures A photograph of the inside of the fill model box.

[0038] The camera uses a CCD camera.

[0039] As for the laser generator, it adopts a continuous type sheet laser or a continuous type point laser with higher power, and cooperates with an appropriate linear generator so that it can be used as a sheet light source.

Embodiment 3

[0041] In a typical implementation of the present invention, embodiment 3 discloses an anchor plate pull-out test method, using an anchor plate pull-out test system as described in embodiment 2, comprising the following steps:

[0042] Step 1: fill the inside 10 of the model box with the prepared transparent soil, put the anchor plate structure 11 into it when the filling reaches the corresponding height, and the outside of the anchor rod passes through the opening 5 of the soil retaining plate and the external loading device connected. Use aforesaid rubber stoppers to plug the soil retaining plate opening 5 on the surface of the soil retaining plate body 6, and the vertical height is lower than the required transparent soil filling height. the same as the existing groove) into the groove at the bottom of the model box;

[0043] Second step: after filling the transparent soil, install the cover plate 13 on the top of the model box interior 10 along the reserved slideway 12, a...

Abstract

The invention discloses an anchor plate pull-out test device, system and method based on transparent soil, belongs to the technical field of anchor plates, and aims to not only reduce disturbance to asoil body when an anchor rod is mounted in a model test, but also achieve an effect of predicting a three-dimensional deformation field of the soil body by observing any tangent plane in a three-dimensional deformation process of the soil body, and there is a condition of observing the displacement deformation of the soil body between the plates in the drawing process of the horizontal double anchors arranged at the same height. The device comprises a soil filling model box, a soil baffle, an anchor rod, an anchor plate and a sealing plug, wherein one side face of the soil filling model box is an open side, the soil baffle is installed on the open side of the soil filling model box in a sliding mode and the anchor rod penetrates through the soil baffle to enter the soil filling model box.The anchor plate is installed in the soil filling model box in the opening side, the anchor rod penetrates through the anchor plate, the soil baffle is provided with a plurality of open holes, and the open holes can be sealed through sealing plugs; and two side surfaces of the filling model box are transparent.

Description

technical field [0001] The invention belongs to the technical field of anchor plates, and in particular relates to an anchor plate pull-out test device, system and method based on transparent soil. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As a large number of roads, railways, water conservancy, mines and other facilities need to be built in high mountains and hilly areas, in engineering practice, it is necessary to face higher and more slope excavation and filling problems, resulting in various problems for high side Support structure scheme for slope problems. Such as anchor-pull retaining wall, anchor plate retaining wall, reinforced soil retaining wall, anti-slide pile and other treatment methods. Among them, the anchor plate retaining wall is one of the more commonly used solutions. When the anchor plate works, it will squeeze the soi...
