Embodiment 1

[0084] Scrap tire pulling test procedure of the present invention is as follows: Figure 9 shown.

[0085] Determine the test conditions, assemble the test box and prepare the packing (involving S1-S2). The burial depth is 1.5m. For a single tire, the tire shape parameters are: tread height 40mm, tire cross-section shape is circular, tire outer diameter 200mm, tire skin thickness 15mm. The internal dimensions of the test box are 600mm×500mm×220mm in length×width×height. Adjust the effective length x width x height of the telescopic loading plate to be 550mm x 400mm x 10mm. The number of channel steels is 8 (4 on each side). The type of filler is sandy soil with a moisture content of 0% and a density of 1.9g / cm 3 , The degree of compaction of the filler in the box is 65%. Place the bottom plate on the level ground, then fix a layer of channel steel on the bottom plate through the screw holes on the channel steel wing plate, then select a rectangular steel plate, select the...

Embodiment 2

[0092] The bearing capacity test steps of waste tire reinforced soil foundation of the present invention are as follows: Figure 10 shown.

[0093] Determine the test conditions, assemble the test box and prepare the filler (involving A1). Two tires are horizontally arranged in a rectangular shape. The tire shape parameters are: tread height 30mm, tire cross-section shape is circular, tire outer diameter 200mm, tire skin thickness 10mm. The internal dimensions of the test box are length x width x height 1500mm x 500mm x 400mm. The adjusted size of the telescopic loading plate is: length×width×height is 1300mm×400mm×20mm. The number of channel steels is 12 (6 on each side). The type of filler is construction waste with a moisture content of 10% and a density of 1.84g / cm 3 , The degree of compaction of the filler in the box is 80%.

[0094] Sample filling (involving A2). The construction waste is loaded in the form of layered filling. The thickness of each layer is 50mm. ...

Abstract

The invention relates to a method for carrying out a bearing capacity and pull-out test on a tire reinforced soil foundation by using the same device. The device comprises a model box system; the model box system comprises a test box formed by detachably splicing a rectangular steel plate, a bottom plate and a plurality of channel steels, the internal size of the model box is adjusted by assembling and disassembling the channel steels, the rectangular steel plate and the bottom plate, and the upper surface of the test box is covered by a telescopic loading plate of the vertical direction load applying system; and a horizontal drawing system is fixed to a waste tire to be tested through a steel wire stay wire, a clamp and a chain rod, the whole strand part, led out after the waste tire is bound by the steel wire stay wire, and the chain rod are always on the same straight line, and the whole strand part and the chain rod are located in the axis of the clamp. The method comprises a waste tire pull-out test and a waste tire reinforced soil foundation bearing capacity test. According to the method, the foundation bearing capacity experiment and the pull-out test can be completed, the whole tire structure can be pulled out, the box body structure can be suitable for various tire sizes, and the adaptability is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering and geological engineering tests, in particular to a method for carrying out tire-reinforced soil foundation bearing capacity and tire pull-out tests with the same device. Background technique [0002] In recent years, the amount of waste tires produced each year in my country ranks first in the world for many years, and the annual scrapping volume has increased dramatically year by year. The accumulation of a large number of waste tires not only occupies land, but also seriously pollutes the natural environment and endangers the health of residents. Improper disposal of them will cause serious environmental problems. How to efficiently recycle waste tires scientifically, environmentally friendly, safely and economically is a major practical problem to be solved urgently. Due to the characteristics of good durability, hoop tensile strength and tread friction, waste tires have been used ...
