Problems solved by technology

[0006] A visual test device and test method for anchor slab pullout is proposed to solve the problem that the previous test device cannot accurately analyze the weakening effect of the pullout bearing capacity of the anchor slab due to the lack of simulation of heavy rainfall-drought extreme climate. Realize the multi-directional pull-out test of the anchor plate under this special condition

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as Figure 1 to Figure 4 A visual test device for anchor plate drawing is shown, including anchor plate 10, test box 18, heavy rainfall-drought extreme climate simulation system, loading system and measurement system, and the test box 18 is the front side The box structure can be flipped open and the top is provided with a pullable cover plate. There is a water storage tank 12 on the left and right sides of the test box. The inner surface of the water storage tank 12 is provided with a permeable geotextile 8. A water level control hole 9 is provided at the contact part with the permeab...

Abstract

The invention discloses a visual test device for carrying out anchor plate drawing, which comprises an anchor plate, a test box body, a heavy rainfall-drought extreme climate simulation system, a loading system and a measuring system, and is characterized in that the test box body is of a box body structure of which the front side surface can be turned over and opened and the top is provided with a drawable cover plate; the heavy rainfall-drought extreme climate simulation system comprises an artificial rainfall device and an infrared baking lamp; the loading system comprises a loading frame, an electric actuator, a pulley block and a steel wire rope connected to the pulley block; and the measuring system comprises a load displacement sensor, a data acquisition instrument, a multi-layer soil parameter detector, a high-pixel digital camera and a computer. The problem that the weakening effect of the uplift bearing capacity of the anchor plate cannot be accurately analyzed due to the fact that a previous test device does not simulate the heavy rainfall-drought extreme climate is solved, and a multi-directional pull-out test of the anchor plate under a special condition is achieved.

Description

technical field [0001] The invention relates to the technical field of geotechnical model test devices, in particular to a visual test device and a test method for anchor plate drawing. Background technique [0002] As a form of foundation that provides pull-out resistance, anchor plates have been used in high-rise structures such as communication towers and transmission towers, and anchor plate retaining walls and other slope projects because of their advantages such as simple construction, good economy, and strong bearing capacity. has been widely used. [0003] my country has a vast land area and complex and diverse geological conditions. Under certain soil conditions, if heavy rainfall and drought alternate, the soil will often be in a dry-wet cycle state, resulting in a large number of cracks, resulting in a decline in its mechanical properties. Prone to cracking or sliding damage. The relationship between the embedding depth of the anchor plate and the depth affected ...
