[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1: Please refer to Figures 1-4 The underground passageway protection structure of the terminal building includes the passageway body 1. A pressure component 2 is installed on the inner wall of the passageway body 1 near the top. The pressure component 2 includes a floating cover plate 21, which is slidably installed on the inner wall of the passageway body 1 near the top. Moisture-absorbing components 3 are fixedly installed on the left and right outer walls of the passageway body 1. A drainage component 4 is fixedly installed on the bottom surface of the passageway body 1. The drainage component 4 is connected to a water storage tank 5.

[0038] It should be noted that the bottom surface of the passage trench body 1 is provided with several vertically connected drainage holes at equal intervals, and several drainage holes are connected to the inside of the drainage component 4.

[0039] Several sliding columns 11 are fixedly installed on the inner walls of both sides of the passage trench body 1. Several vertical sliding holes are opened on both sides of the top surface of the floating cover plate 21. Several sliding holes are slidably sleeved on the outer walls of several sliding columns 11. A first spring 22 is sleeved on the outer wall of several sliding columns 11. The top of several first springs 22 abuts against the bottom surface of the floating cover plate 21. Liquid storage cylinders 24 are fixedly installed on the inner walls of both sides of the passage trench body 1. A first sliding rod 23 is slidably installed on the inner wall of two liquid storage cylinders 24. The top of two first sliding rods 23 away from the liquid storage cylinders 24 is fixedly connected to the bottom surface of the floating cover plate 21. Connecting pipes 25 are installed on the bottom surface of two liquid storage cylinders 24.

[0040] It should be noted that the first spring 22 has a resetting function for the floating cover 21. The inner walls of both sides of the passage trench body 1 are welded and fixed with fixing plates 12. The two liquid storage cylinders 24 are respectively fixed to the top surface of the two fixing plates 12 by bolts. The liquid storage cylinders 24 store silicone oil. A piston is installed at the bottom of the first sliding rod 23. When the floating cover 21 is under pressure, the floating cover 21 drives the piston to move through the first sliding rod 23, compressing several first springs 22 and discharging the silicone oil inside the liquid storage cylinder 24 into another component through the connecting pipe 25. When the pressure on the floating cover 21 is removed, several first springs 22 release their elasticity to reset the floating cover 21. The floating cover 21 drives the piston to move through the first sliding rod 23, and the piston draws the silicone oil back into the liquid storage cylinder 24 through negative pressure.

[0041] Example 2: Please refer to Figures 2-10 The difference between the protective structure of the underground passage trench in the terminal building and that in Embodiment 1 is that the moisture absorption component 3 includes a moisture absorption box 31. The moisture absorption box 31 has several moisture absorption holes 311 equidistantly opened on the end face away from the passage trench body 1. The top of the inner wall of the moisture absorption box 31 is rotatably connected to a squeezing plate 32. The inner wall of the moisture absorption box 31 is hinged to a sliding cylinder 34 near the inner wall of the passage trench body 1. The end of the connecting pipe 25 away from the liquid storage cylinder 24 is connected to the sliding cylinder 34. The inner wall of the sliding cylinder 34 is slidably connected to a second sliding rod 35. The end of the second sliding rod 35 away from the sliding cylinder 34 is hinged to the squeezing plate 32.

[0042] It should be noted that an extension plate 33 is slidably installed at the bottom end of the extrusion plate 32. A water-absorbing sponge is sandwiched between the extrusion plate 32 and the inner wall of the moisture-absorbing box 31 away from the main body 1 of the passage ditch. The water-absorbing sponge absorbs and stores the moisture from the soil outside the moisture-absorbing box 31 through the moisture-absorbing holes 311. When the floating cover plate 21 is under pressure, the floating cover plate 21 drives the piston to move through the first sliding rod 23, compressing several first springs 22, and discharging the silicone oil inside the liquid storage cylinder 24 into the sliding cylinder 34 through the connecting pipe 25. The end of the second sliding rod 35 away from the extrusion plate 32... A piston is installed in the part. The silicone oil pushes the piston to drive the second sliding rod 35 to slide on the inner wall of the sliding cylinder 34. The second sliding rod 35 drives the extrusion plate 32 and the extension plate 33 to rotate inside the moisture absorption box 31. The extrusion plate 32 and the extension plate 33 together squeeze the water-absorbing sponge, and the water inside the water-absorbing sponge is squeezed out. The bottom surface of the moisture absorption box 31 is provided with a drain outlet, which is connected to the inside of the drainage component 4. Most of the water enters the drainage component 4 through the drain outlet, thereby avoiding excessive soil moisture on the outer wall of the moisture absorption component 3 and preventing the passage ditch body 1 from settling.

[0043] The drainage assembly 4 includes a drainage tank 41. A sliding frame 411 is fixedly installed on the top surface of the drainage tank 41. An airbag 42 is slidably installed on the inner wall of the sliding frame 411. A connecting rope 43 is fixedly installed at the center of the bottom surface of the airbag 42. A sliding cylinder 44 is fixedly installed on the bottom surface of the drainage tank 41. A water suction pipe 441 is fixedly installed on the top surface of the sliding cylinder 44. The end of the water suction pipe 441 away from the sliding cylinder 44 passes through the side wall of the drainage tank 41 and is connected to the water storage tank 5. A moving piston 45 is slidably installed on the inner wall of the sliding cylinder 44. A second spring 46 is sandwiched between the bottom surface of the moving piston 45 and the bottom surface of the drainage tank 41. A water inlet groove is opened on the outer wall of the sliding cylinder 44 near the bottom. The end of the connecting rope 43 away from the airbag 42 passes through the side wall of the sliding cylinder 44 and is fixedly connected to the bottom surface of the moving piston 45.

[0044] It should be noted that the airbag 42 is filled with gas. A pulley is rotatably connected to the bottom of the drain tank 41 directly below the airbag 42. The connecting rope 43 is sleeved on the outer wall of the pulley, which acts as a guide, reducing frictional wear on the connecting rope 43 and extending its service life. The height of the water storage tank 5 is lower than the height of the sliding cylinder 44. The sliding cylinder 44, located above the moving piston 45, and the suction pipe 441 are filled with water. When the water level inside the drain tank 41 exceeds a certain height, it may enter the passageway body 1, affecting the pipeline. At this time, the airbag 42, slidably connected inside the sliding frame 411, floats up. A sliding ring is fixedly installed on the outer wall of the airbag 42, and the sliding ring is slidably connected to the inner wall of the sliding frame 411. The sliding frame 411 guides the sliding ring and the airbag 42. The sliding cylinder 44 is fixedly installed on the bottom surface of the drain tank 41 by bolts. The airbag 42 pulls the moving piston 45 through the connecting rope 43. The moving piston 45 moves downward and compresses the second spring 46 until the moving piston 45 moves below the water inlet of the sliding cylinder 44. Since the water level on the inner wall of the drain tank 41 is higher than the water inlet at this time, the sliding cylinder 44 and the suction pipe 441 form a siphon effect, thereby draining the water inside the drain tank 41 to the water storage tank 5 through the suction pipe 441. When the water level inside the drain tank 41 drops, the airbag 42 moves down with the water level, the second spring 46 releases its elastic force to reset the moving piston 45, and the moving piston 45 closes the sliding cylinder 44 again.

[0045] Working principle: During use, a floating cover plate 21 is installed near the top of the passage trench body 1. The floating cover plate 21 slides with the sliding column 11 through several sliding holes and is reset by the first spring 22. When external pressure is applied to the floating cover plate 21, the floating cover plate 21 presses down and drives the piston of the first sliding rod 23 to move inside the liquid storage cylinder 24. At this time, the first spring 22 is compressed, and the piston of the first sliding rod 23 discharges the silicone oil in the liquid storage cylinder 24 into the sliding cylinder 34 through the connecting pipe 25. When the external pressure is removed, the first spring 22 releases its elastic force to push the floating cover plate 21 to reset. At the same time, the first sliding rod 23 drives the piston to generate negative pressure, which draws the silicone oil back into the liquid storage cylinder 24, thus realizing the reset of the floating cover plate 21.

[0046] After the silicone oil is discharged into the sliding cylinder 34, the silicone oil pushes the piston at the end of the second sliding rod 35 to slide on the inner wall of the sliding cylinder 34. The second sliding rod 35 drives the extrusion plate 32 and the extension plate 33 to rotate inside the moisture absorption box 31 and compress the water-absorbing sponge. When the water-absorbing sponge is compressed, it discharges the stored water into the drainage component 4 through the drain outlet, thereby effectively reducing the humidity of the soil outside the passage ditch body 1 and preventing the passage ditch body 1 from settling.

[0047] Meanwhile, the drainage component 4 constitutes an automatic drainage mechanism that can drain water in a timely manner. When the water level inside the drainage tank 41 rises above the safe height, the airbag 42 moves upward under the action of buoyancy and pulls the moving piston 45 downward through the connecting rope 43, compressing the second spring 46 until the moving piston 45 descends to below the water inlet of the sliding cylinder 44. During this process, the water level on the inner wall of the drainage tank 41 is higher than that in the water inlet. The sliding cylinder 44 and the suction pipe 441 above the moving piston 45 are filled with water. The sliding cylinder 44 and the suction pipe 441 form a siphon effect with the water inside the drainage tank 41, thereby draining the water inside the drainage tank 41 into the water storage tank 5 arranged at a lower position. When the water level drops, the airbag 42 moves downward accordingly, the second spring 46 releases its elastic force to reset the moving piston 45, and the sliding cylinder 44 closes again, completing one automatic drainage cycle. At this point, the operation of this device is completed.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
