Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying, and particularly relates to an inclinometer for a soil reduced-scale model. Background Art

[0002] Since the occurrence of an earthquake often triggers the deformation and flow of soil mass, resulting in the complete destruction or even burial of large-scale buildings, and half of the foundation failures caused by earthquakes are caused by soil liquefaction. Among them, the zero effective influence state of some foundation soil masses during and after an earthquake, the zero effective stress state of liquefied foundation soil masses, and the hydrodynamic response mechanism of soil mass under earthquake damage conditions have always been the research key points and difficulties in geotechnical engineering surveying.

[0003] In the prior art, for the hydrodynamic response of liquefied soil mass, it is mainly to interact with the soil mass in the liquefied site and use a follow-up mechanism arranged in the soil mass to measure the flow direction. However, generally, the overall test device is relatively complex, and the visualization degree of test results is relatively low. During the process of simulating the soil mass flow, the study of different motion conditions generated in the system is lacking, resulting in certain limitations in the test measurement results.

[0035] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments.

[0036] The embodiment of the present utility model provides an inclinometer for a soil reduced-scale model, as Figures 1 to 3 shown. The inclinometer for the soil reduced-scale model includes:

[0037] A measurement box body 100, the measurement box body 100 having three groups of opposite working surfaces 110, and each group of opposite working surfaces 110 includes a first working surface 111 and a second working surface 112;

[0038] A measured piece 200, the measured piece being arranged inside the measurement box body 100;

[0039] An X-ray projection component 300, where the number of the X-ray projection components 300 is one or two or three, and one X-ray projection component 300 is installed on a group of opposite working surfaces;

[0040] The X-ray projection component 300 includes an X-ray emitter 310 and an imaging plate 320. The X-ray emitter 310 is installed outside the first working surface 111, and the imaging plate 320 is installed outside the second working surface 112. The X-ray emitter 310 is used to emit X-rays towards the imaging plate 320, and the emitted X-rays pass through the measurement box body 100 and detect the measured piece 200 inside the measurement box body 100, so as to display the detection result on the imaging plate 320.

[0041] It should be noted that the X-ray detection component 300 described in this embodiment has basically the same working principle as that of an existing X-ray machine. Briefly speaking, the X-ray emitter 310 emits X-rays. The measurement box 100 is made of a material that can be penetrated by X-rays. X-rays themselves can penetrate the soil body (such as sand) disposed in the measurement box 100, while the measured object 200 is made of a material that can block X-rays. Therefore, the detection result, that is, a segment of image data, will finally be obtained on the imaging plate 320. This segment of image data reflects the movement process of the measured object 200 in the soil body simulation experiment. During the experiment, the measured object 200 is placed in the measurement box 100 filled with the soil body. Therefore, the movement process of the measured object 200 can reflect the movement process of the soil body to a certain extent. Especially in some soil body change experiments that occur in a short time, the present utility model can quickly and accurately record the corresponding image data to realize the visualization of soil body flow detection.

[0042] As Figure 1 shown, according to the actual situation, the X-ray detection component 300 can be set to one, two, or three, corresponding to three sets of opposite working surfaces 110 respectively, which are equivalent to the x, y, and z axes of the spatial coordinate system. When the X-ray detection component 300 is two or three, as Figure 4 shown, the inclinometer for the soil scale model further includes a total display 400. The imaging plates 320 in two or three X-ray detection components 300 are connected to the total display 400 to display the detection results on the imaging plates 320 in two or three X-ray detection components in the total display 400. When displayed in the total display 400, a split-screen method can be adopted for display, that is, multiple display grids are divided on one screen. Among them, three display grids respectively correspond to displaying the images detected by one imaging plate 320. There can also be one display grid for displaying the composite image obtained according to the images fed by two or three imaging plates 320. The composite method is a prior art and will not be described in detail here. When two or three imaging plates 320 are set, the composite images are two-dimensional images and three-dimensional images respectively. In this way, the present utility model can obtain rich visualization soil body flow detection data.

[0043] In some embodiments, in order to ensure the best imaging effect, a linear motor 500 is disposed outside the first working surface 111, and the X-ray emitter 310 is installed on the linear motor 500. By adjusting the linear motor 500, the position of the X-ray emitter 310 can be adjusted, thereby adjusting the X-ray focus to adjust the X-ray detection range and ensuring that the detected object 200 can be completely covered by the X-ray detection range.

[0044] In some embodiments, as Figure 2As shown, the inclinometer device for the soil scaled model further includes a box support 600, and the box support 600 supports the measurement box 100, such that there is a certain space between the measurement box 100 and its placement plane, and this space is used to ensure the installation of the X-ray emitter 310.

[0045] In some embodiments, as Figure 5 shown, the measured object 200 includes a connecting rope 210, iron rings 220, and end heads 230; a plurality of iron rings 220 are provided, and the plurality of iron rings 220 are wound around the connecting rope 210; two end heads 230 are provided, and are respectively arranged at both ends of the connecting rope 230. The two end heads 230 serve to prevent the plurality of iron rings 220 from falling off the connecting rope 210. The plurality of iron rings 220 are closely attached to each other, and the measured object 200 is formed by winding the connecting rope 210. The iron rings 220 can be detected by X-rays. In the soil model experiment, when the soil undergoes displacement changes, the measured object 200 located in the soil will also undergo displacement, and this displacement can be detected by the X-ray detection assembly 300.

[0046] In some embodiments, a first through hole 120 and a second through hole 130 are respectively provided at the top and bottom of the measurement box 100, and a seal-opening assembly 131 is provided in the second through hole 130. The first through hole 120 is used to add soil into the measurement box 100, and the second through hole 130 is used to discharge the soil after the experiment is completed.

[0047] In some embodiments, a partition plate 140 is provided inside the measurement box 100, a number of third through holes 150 are provided on the partition plate 140, and valves 160 are provided in each of the third through holes 150. The partition plate 140 divides the interior of the measurement box 100 into a first space 170 and a second space 180. The first space 170 is located above the second space 180, and the measured object 200 is arranged in the first space 170.

[0048] This embodiment provides a soil experiment based on a soil reduced-scale model. Simply speaking, it is a quicksand experiment. Before the experiment, a certain amount of sand is added into the measurement box body 100 through the first through hole 120, and at this time, the valve 160 is in a closed state. The top cover of the measurement box body 100 (i.e., the side provided with the first through hole 120) is set to be openable, such as a flip-type cover body. Open the top cover, place the measured part 200 in the sand body formed by the sand, and then close the top cover. Then turn on the X-ray illumination component 300. According to the experimental requirements, the valve 160 in the corresponding third through hole 150 can be opened, and the outflow rate of the sand is controlled by the opening degree of the valve 160. At this time, the sand in the first space 170 gradually flows out into the second space 180. During this process, the second through hole 130 is sealed by the unsealing component 131. The unsealing component 131 can be an unsealing cover body or an unsealing valve, and this embodiment does not specifically limit it here. Since the sand in the first space 170 gradually loses, the sand body deforms, and the measured part 200 follows and flows. The image data detected by the X-ray illumination component 300 can reflect the deformation process of the sand body to a certain extent, realizing the visualization of soil flow detection. After the experiment is completed, open the unsealing component 131 to drain all the sand. The size of the detecting part 200 is set to be larger than that of the third through hole 150, so it will not fall into the second space 180. In order to better drain the sand, the second through hole 130 is connected to a discharge pipe, and the sand is collected into a collection container through the discharge pipe, and then the collected sand is reused, that is, repeat the above experimental preparation. During the experiment, adjust the opening number of the third through hole 150 and the corresponding valve opening degree to simulate different quicksand scenarios.

[0049] In some embodiments, in order to facilitate the control of the experimental scenario, the valve 160 is selected as an electromagnetic valve.

[0050] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical fields can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
