Problems solved by technology

[0003] At present, the test chambers in the prior art mainly have the following deficiencies: (1) The test chamber is small in size and cannot be changed, so it can only do conventional small model tests, and the test chamber cannot change the stress of the soil; ( 2) The test efficiency is low, only one test pile can be produced each time, the process is cumbersome, and there are many repetitive tasks; (3) It is difficult to evenly distribute the soil in the test box, the vibration process is long, and the effect is poor

Abstract

The invention discloses a multifunctional stirring model test box and a use method thereof, and belongs to the field of indoor test equipment. The test box comprises a base, a formwork system, a support, a fixed frame, a drill rod, angle iron and an angle support. The formwork system comprises a front side formwork, a rear side formwork, a left side formwork, a right side formwork, and a top formwork, the support comprises a vertical rod structure and a transverse rod structure, the transverse rod structure is provided with a horizontal fixed hole and a baffle, a vertical fixed hole is formedin the baffle, the fixed frame comprises a fixed ring, a fixed rod and a fixing device, the fixed ring comprises an upper cover plate, a lower cover plate, a bearing and a bolt hole, the fixed rod comprises a wedge body, a rod body, and bolt holes, and the fixing device comprises a fixing device body, side lugs and bolt holes. In-situ stress conditions of actual soil can be simulated, experiment data are more reasonable, free moving of the drill rod is achieved, multiple piles can be made in one-time experiment, and the experiment efficiency can be improved.

Description

technical field [0001] The invention relates to the field of indoor test equipment, in particular to a multifunctional stirring model test box and a using method thereof. Background technique [0002] The in-situ test of the pile foundation is a method to test the reinforcement effect of the pile foundation on the foundation, but the in-situ test consumes a lot of manpower, material resources, and financial resources, and the test cost is extremely high; and the conditions of the field test site are complex and changeable. Too many control factors often lead to greater randomness in the test results and insignificant changes in the relevant laws. For this reason, the indoor model test of the pile foundation came into being as a method to test the reinforcement effect of the foundation and study the reinforcement mechanism of the pile foundation. The indoor pile foundation model test is to scale down the in-situ foundation and piles to a certain proportion, to set various fa...
