Testing device for power transmission line foundation test and setting method thereof

Abstract

The invention discloses a testing device for power transmission line foundation test and a setting method thereof. Organic glass piles are gradually pressed into soil symmetrically from the middle to two directions, not only effectively simulate the program of gradual piling in the practical construction site, but also can effectively avoid the problem that soil is extruded to one direction, so that the soil is not uniformly extruded or the soil is severely extruded to cause a model pile which is pressed into the soil in advance to be inclined, and enables test results to be more accurate; after the organic glass piles are gradually pressed into the soil, assembled with a model bearing platform, and then are filled with chloroform, so that the organic glass piles are connected with the model bearing platform, the method is simple and efficient, and the problems that grouped piles are pressed into soil at the same time to cause high time consumption and power consumption can be effectively prevented; in addition, organic glass model components are sufficiently and fixedly connected with one another through the chloroform, so that the components can be applied to tests of pulling upwards and pressing down.

Description

technical field [0001] The invention belongs to the technical field of pile group foundation model tests in geotechnical engineering, in particular to a test device and a setting method for foundation tests of power transmission lines. Background technique [0002] Pile group foundation is an important content of construction engineering, and experimental research is an important method to study pile group foundation. Since it is difficult and expensive to carry out field tests, the large-scale pile group model simulation test can not only simulate the field stress field, study the deformation and instability mechanism of the foundation, but also be easy to carry out and relatively low in cost. Basic model tests are of great significance. [0003] In general foundation model tests, the pile group model is first assembled and then pressed into the soil. This method will cause greater difficulty when applied to the pile group foundation test. Simultaneous pressing of pile gr...

AI Technical Summary

Problems solved by technology

It is time-consuming and labor-intensive to press in the pile group model at the same time, and it is more likely that it cannot be completely pressed in

Moreover, pressing in a large number of pile models at the same time will cause the soil to be severely squeezed and cause the pile model to tilt, which will cause unfavorable situations such as uneven stress on the pile model and inaccurate experimental results.

[0004] Due to the existence of the above-mentioned problems, the existing test methods will cause cumbersome test operations and low accuracy of results when performing pile group foundation model tests
