Problems solved by technology

[0006] First of all, most of the current indoor compaction test devices only have a single compaction function. In addition to providing stable compaction efficiency, the vibration frequency and power of the load cannot be changed.
Secondly, most of the current indoor compaction test devices only realize the function of applying pressure to the steel box, but there is no test device with the function of laying geosynthetics in the filler and then simulating the soil compaction process

Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0044] refer to figure 1 A construction damage test device for geosynthetic materials includes a support assembly, a combined steel box, a loading device and a driving device arranged thereon.

[0045] The combined steel box is used to fill the rammed earth, and the geosynthetic material 17 is laid between the rammed earth, the driving device is connected with the loading device, the driving device is used to provide power for the loading device, and the loading device is used for the geotechnical The synthetic material 17 applies pressure.

[0046] The bracket assembly includes a steel base plate 20, and a motor mount 1, a column 9 and an eccentric device support 19 arranged on the top, the drive device is installed on the motor mount 1, and the output shaft of the drive device is prov...

Abstract

The invention discloses a geosynthetics construction damage test device, comprising a combined steel box, a loading device and a driving device, wherein the loading device drives a driving connectingrod to alternately reciprocate up and down through an eccentric wheel mechanism, so that the driving connecting rod drives a compression plate to perform a loading test on the filled earth and the geosynthetics in the combined steel box; and by adoption of the eccentric wheel mechanism, the loading height of the compression plate can be achieved by changing the eccentric distance of an eccentric wheel, and meanwhile the rotation speed of the driving device is changed to realize the loading frequency of the compression plate. The test device can complete an indoor geosynthetics construction damage test, can control the progress of the test, ensure the uniform stress of the soil body in the steel box and fully compress the soil body; the accuracy of the geosynthetics construction damage testis ensured; and an outdoor geosynthetics construction damage test is truly restored.

Description

technical field [0001] The invention belongs to the technical field of geotechnical testing instruments, in particular to an indoor testing device for construction damage of geotechnical synthetic materials. Background technique [0002] Geosynthetics will be damaged to varying degrees during laying and filling compaction, resulting in a reduction in strength. Since the strength reduction of geosynthetics caused by construction is a factor that must be considered in design, the construction damage reduction factor is an important parameter to measure the strength of geosynthetics due to damage during construction. [0003] During the construction process of geosynthetics, there are many influencing factors and the randomness is large, so it is difficult to determine the reduction coefficient of construction machinery damage during design. The construction damage of geosynthetics is not only related to the material and type of the material itself, but also related to constru...
