Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0054] As Figures 1 to 13 shown, the application provides a test device for the influence of a water ditch cover plate on the temperature and humidity in a tunnel hole, comprising a tunnel model 1, a temperature and humidity monitoring module 2 and an underground hot water seepage simulation module 5, and further comprising:

[0055] A water ditch cover plate unit 3, the water ditch cover plate unit 3 is provided with multiple groups, and is clamped inside the tunnel model 1;

[0056] A separation module 6, the separation module 6 is movably clamped in the middle end region of the inner cavity of the water ditch cover plate unit 3;

[0057] The sinking assembly 7 is movably connected to one side of the partition module 6 and is fixedly connected to the shielding assembly 8 at the top;

[0058] The partition module 6 comprises a partition block 61 movably connected to the inner cavity of the gutter cover unit 3. The partition block 61 movably connects a moving plate 64 inside. The end of the moving plate 64 away from the partition block 61 is abuttingly connected to a push block 63 movably connected to the inside of the partition block 61. The push block 63 is magnetically connected to the contact end of the partition block 61. The lower end of the partition block 61 movably connects a resisting rod 66 on one side close to the sinking assembly 7.

[0059] The sinking assembly 7 comprises a movable block 71 and a tight pulling assembly 72. The movable block 71 comprises a U-shaped shell 711 movably connected to the inner cavity of the gutter cover unit 3. The U-shaped shell 711 is fixedly connected to a positioning block 712 on the side wall close to the partition block 61. The bottom end of the positioning block 712 is abuttingly connected to the resisting rod 66.

[0060] The tight pulling assembly 72 comprises an elastic block 721. The elastic block 721 is arched. The bottom end of the elastic block 721 is fixedly connected to the top of the adjacent two U-shaped shells 711 on both sides. The lower end of the elastic block 721 movably connects a trapezoidal plate 722 inside the adjacent side wall. The upper end of the elastic block 721 movably connects a rubber film 723 inside the adjacent side wall.

[0061] As shown in Figure 4 and Figure 5 , the gutter cover unit 3 comprises a cover plate 31. Two cavities 32 of different sizes are formed in the inner cavity of the cover plate 31. A protrusion is arranged in the inner cavity of each cavity 32.

[0062] By using the above scheme: the two cavities 32 of different sizes are specifically divided into a first cavity 32, i.e., a larger size; and a second cavity 32, i.e., a smaller size; and in combination with Figure 5 It can be seen that the lower end of the inner wall of the second cavity 32 of the smaller size is fixedly connected to a protrusion for limiting the partition module 6. The partition module 6 is movable in the inner wall of the second cavity 32 of the smaller size. The sinking assembly 7 is movable in the first cavity 32 of the larger size.

[0063] As shown in Figure 6 , Figure 7 , Figure 12 and Figure 13 , the top of the partition block 61 is provided with a Z-shaped block 62. One end of the Z-shaped block 62 is connected to the shielding assembly 8. The bottom end of the partition block 61 is abuttingly connected to the protrusion of the single cavity 32. The moving plate 64 is elastically connected to the partition block 61 through a first spring 65. The bottom surface of the resisting rod 66 is fixedly connected to a second spring 67 on both ends. The resisting rod 66 is elastically connected to the partition block 61 through the second spring 67.

[0064] By using the above scheme: in combination with Figure 12It can be seen that the groove at the top end of the Z-shaped block 62 is clamped at the bottom end of the shielding assembly 8, and part of the bottom end of the shielding assembly 8 is also clamped at the top of the partition block 61. The downward pressure on the stop rod 66 causes it to press the moving plate 64 and gradually make the moving plate 64 abut against the push block 63, so that the push block 63 gradually has a gap with the magnetic attraction surface of the partition block 61, and is unfolded. At this time, the push block 63 moves away from the partition block 61.

[0065] As shown in Figure 6 , Figure 7 , Figure 12 and Figure 13 , the bottom of the positioning block 712 is provided with a third spring 713, and the positioning block 712 is elastically connected with the partition block 61 through the third spring 713.

[0066] After the positioning block 712 is subjected to external force and moves downward, it will gradually press the stop rod 66, so that the stop rod 66 moves downward and presses the moving plate 64 to move inside the partition block 61.

[0067] As shown in Figure 8 , the side of the trapezoidal plate 722 away from the elastic block 721 abuts against the cover plate 31, and the inside of the elastic block 721 is provided with an air cavity.

[0068] By adopting the above scheme: when the two adjacent U-shaped shells 711 move downward, the elastic blocks 721 on the top surfaces thereof will move downward synchronously. At this time, the trapezoidal plate 722 will gradually contact the cover plate 31, and because of the obstruction of the cover plate 31, the trapezoidal plate 722 will gradually move towards the inside of the elastic block 721, and press the gas in the air cavity corresponding to the trapezoidal plate 722, so that the gas gradually flows into the air cavity corresponding to the rubber film 723, and then the rubber film 723 is inflated and expands outwardly. With the downward movement of the elastic block 721, the inflated rubber film 723 will abut against the side wall of the cover plate 31, thereby improving the close-fitting effect of the elastic block 721 on the adjacent two cover plates 31, and improving the fastening of the plurality of cover plates 31 after splicing.

[0069] As shown in Figures 9 to 11 , the shielding assembly 8 comprises a positioning frame 81 fixed on the top of the positioning block 712, the positioning frame 81 is arc-shaped, and the bottom ends of the two sides thereof are respectively fixed on the top of the two adjacent positioning blocks 712.

[0070] The positioning frame 81 is provided with a plurality of groups, and the top of the plurality of groups of positioning frames 81 is fixed on the tunnel model 1 through the power module 4.

[0071] Adopting the above scheme: the contact end of the positioning frame 81 with the Z-shaped block 62 is a semicircular block protruding outward, and is located at the top of the spacer block 61 and is made of rubber. When the positioning frame 81 moves downward, the positioning block 712 and the spacer block 61 move downward synchronously. When the spacer block 61 is in contact with the protruding block on the inner wall of the cover plate 31, the spacer block 61 will not move, but the positioning frame 81 will continue to move downward due to the driving of the power module 4. As a result, the semicircular rubber block protruding outward of the positioning frame 81 is deformed by being pressed by the Z-shaped block 62, and gradually separates from the clamping of the Z-shaped block 62, so that the positioning frame 81 can continue to drive the positioning block 712 to move downward.

[0072] As shown in Figure 10 and Figure 11 , the top of the inner cavity of the positioning frame 81 is provided with a folding plate 82, the top of the folding plate 82 is fixedly connected with the positioning frame 81, and the bottom of the folding plate 82 is movably connected with the inner wall of the positioning frame 81.

[0074] As shown in Figure 10 and Figure 11 , one end of the horizontal rod 84 extends to the top surface of the cover plate 31, one end of the horizontal rod 84 located in the inner cavity of the positioning frame 81 is in contact with a vertical rod 83, one end of the vertical rod 83 away from the horizontal rod 84 is provided with a flexible spring, and the vertical rod 83 is elastically connected with the positioning frame 81 through the flexible spring.

[0075] The top end of the vertical rod 83 is located on the bottom surface of the folding plate 82 and blocks the folding plate 82, and the contact end of the horizontal rod 84 and the vertical rod 83 is provided with an inclined block.

[0076] Adopting the above scheme: with the downward movement of the positioning frame 81, the horizontal rod 84 moves synchronously. When the horizontal rod 84 moves downward with the positioning frame 81, one end of the horizontal rod 84 is blocked by the cover plate 31, the horizontal rod 84 moves upward to drive the inclined block to contact the vertical rod 83, so that the vertical rod 83 moves away from the horizontal rod 84 under the contact of the inclined block of the horizontal rod 84. At this time, the top end of the vertical rod 83 will release the block of the bottom of the folding plate 82, the folding plate 82 is pulled by the tension spring sleeved on the outer wall of the vertical shaft, and the folding plate 82 is unfolded to block the temperature and humidity area at different positions, thereby improving the accuracy of the test.

[0077] As shown in Figure 2 and Figure 3 , the bottom of the power module 4 is fixedly connected with the top of the positioning frame 81, and the top of the power module 4 is fixedly connected with the inner cavity of the tunnel model 1.

[0079] The underground hot water seepage simulation module 5 is installed in the tunnel model 1 and placed directly below the water ditch cover plate unit 3 for simulating the underground water seepage, the water ditch cover plate unit 3 comprises a hot water seepage driving assembly, a water pipe and a hot water tank, the hot water seepage driving assembly comprises a guide rail, a sliding block, a traction rope and a driving module, the sliding block is nested on the guide rail, the two ends of the sliding block are connected with the traction rope, and the sliding block can move longitudinally along the guide rail under the traction of the driving module, thereby realizing the simulation of the hot water seepage of the transverse drain pipe at different positions.

[0080] A test method for the influence of the water ditch cover plate on the temperature and humidity in the tunnel hole, the test method is as follows:

[0081] S1, first splice multiple water ditch cover plate units 3, place them above the underground hot water seepage simulation module 5, turn on and adjust the partition temperature control system, simulate the abnormally high geothermal area caused by high rock temperature and underground hot water seepage, and restore the temperature field distribution of the actual tunnel;

[0082] S2, in the initial state, the partition module 6, the sinking assembly 7 and the shielding assembly 8 are all located above the water ditch cover plate unit 3, at this time the cavity 32 will not be separated, the cavity 32 forms an integral cavity, turn on the underground hot water seepage simulation module 5 and record the change value of the temperature and humidity in the tunnel model 1 when the cover plate 31 forms an integral cavity;

[0083] S3, the partition module 6 is driven by the power module 4 to separate the cavity 32, that is, the single integral cavity 32 is separated into two separate cavities, and then the temperature and humidity monitor 22 detects and records the change of the temperature and humidity in the tunnel model 1 when the number of cavities 32 for flowing on the cover plate 31 increases, and the increase of the number of cavities for gas flow in S1 and S2 is compared, so as to observe the change of the temperature and humidity in the tunnel model 1;

[0084] S4, the positioning frame 81 is continuously lowered by the power module 4, at this time the depth of one of the two cavities 32 will increase, and the depth of the other cavity will not change, at this time the temperature and humidity monitor 22 can detect the comparative change of the temperature and humidity when cavities of different depths are used for gas flow under the condition that the number of cavities is the same;

[0085] S5, the lower movement of the U-shaped shell 711 will make the push block 63 move through the abutting rod 66 and the moving plate 64, and the push block 63 will reduce the space inside one of the two cavities, and the temperature and humidity changes are compared through the temperature and humidity monitor 22;

[0086] S6, the water ditch cover plate unit 3 under normal circumstances is divided into two separate cavity water ditch cover plate units 3, that is, the cavity for gas flow is increased, the water ditch cover plate unit 3 under different depth conditions and the cavity inside space of the water ditch cover plate unit 3 are compared, and then the case of the water ditch cover plate unit 3 which has the greatest influence on the temperature and humidity inside the tunnel model 1 is compared.
