Test device and setting method for foundation test of transmission line

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 model test of group pile foundations of geotechnical engineering, in particular to a test device for foundation test of power transmission lines and a setting method thereof. Background technique [0002] Pile group foundation is an important part of construction engineering, and experimental research is an important method to study group pile foundation. Since it is difficult and expensive to carry out the real-type test on site, 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 is easy to carry out and relatively low in cost. Basic model testing is of great significance. [0003] In general foundation model test, the pile group model is assembled first, and then pressed into the soil. When this method is applied to the pile group foundation test, it will cause great difficulty. It i...

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
