Embodiment Construction

[0060] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0061] Such as Figure 1~5 As shown, an impact rolling model test device includes a test control box 1, a traction device 2, a sliding guide rail 3, an impact wheel 4, a test box 5, and a main frame 6.

[0062] The test control box 1 can realize the functions of parameter setting and test control; the traction device 2 provides the external power and power transmission mechanism required for the movement of the impact wheel 4; The rod 16 slides parallelly along the track; the impact wheel 4 simulates the impact wheel of the impact roller, and is connected with the sliding cross bar 16 through the rocker arm 19 and the connecting rod 20; Test environment; the main frame 6 provides a stable placement platform for the components of the device, which is convenient for the overall movement of the test device.

[0063] Wherein, test control box 1 c...

Abstract

The invention belongs to the technical field of geotechnical model test researches and relates to an impact rolling model tester and application thereof. The tester comprises a test control chamber, a traction device, slide guides, an impact wheel, a test chamber and a main framework, wherein the traction device comprises an alternating-current motor, an inhaul cable, a guide pulley and a pulley stay bar; one end of the inhaul cable is fixedly arranged on a winding pulley of the alternating-current motor; the other end of the inhaul cable is connected with a connecting fixed block; the guide pulley is arranged on supports through the pulley stay bar; the slide guides comprise two parallel and horizontal polish rods; sleeves are respectively welded at the top ends of the polish rods; the polish rods are respectively and fixedly arranged at both sides above the test chamber through the sleeves by two supports which are vertical with the ground; and the wheel shaft of the impact wheel is connected with a rocker arm through a connecting rod. According to the impact rolling model tester, an impact rolling action process on a soil body can be simulated. The impact rolling model tester is used for researching the reinforcement mechanism and the influencing factor of the impact rolling technology.

Description

technical field [0001] The invention belongs to the technical field of geotechnical model test research, and relates to an impact rolling model test device and its application. Background technique [0002] The impact rolling method is a shallow foundation treatment method widely used at present. The research on the impact rolling reinforcement technology is mostly limited to the field test and the analysis of engineering experience, and its reinforcement mechanism is not very clear. Therefore, with the help of indoor models Experiment is a very effective method to study the microcosmic mechanism of impact rolling. [0003] The difficulty of the model test lies in the similarity analysis between the model and the prototype, and how to establish an appropriate test model. The impact rolling reinforcement technology has a unique construction process. The key to the model test is to simulate the construction equipment so that it can reasonably reflect the actual process. Ther...
