DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As shown in the accompanying Figures 1-6The waterproof structure of the assembled underground pipe gallery shown comprises a waterproof roll 2 installed outside the pipe gallery 1, a waterproof filling layer 3 arranged between the waterproof roll 2 and the pipe gallery 1, and an assembly joint 4 formed at the connection of every two pipe galleries 1. The waterproof roll 2 and the pipe gallery 1 are matched in shape and size, and the waterproof filling layer 3 is an elastic waterproof glue filled in the gap between the waterproof roll 2 and the pipe gallery 1.

[0022] Specifically, in the structure, the outside of each pipe gallery 1 is paved with the waterproof roll 2, which can avoid the influence of underground water on the concrete pipe gallery 1 and prevent the underground water from penetrating into the interior of the pipe gallery 1 to affect the pipelines inside the pipe gallery 1. The waterproof filling layer 3 filled between the waterproof roll 2 and the pipe gallery 1 is an elastic waterproof glue, which can not only prevent the underground water from penetrating into the interior of the pipe gallery 1, but also has a certain elastic potential to relieve the thermal expansion and contraction stress of the pipe gallery 1 caused by temperature underground.

[0023] Every two pipe galleries 1 are assembled to form an overall pipe gallery 1 structure. After assembly, the assembly joint 4 is formed at the joint of every two pipe galleries 1. The assembly joint 4 is a gap at the joint of the two pipe galleries 1, which is prone to cause the underground water to penetrate into the interior of the pipe gallery 1. The self-adapting sealing structure is used to seal and waterproof the gap again, thereby improving the waterproof performance of the pipe gallery 1.

[0024] In specific embodiments, as shown in the accompanying drawings, Figure 1 , 3 As shown, the self-adapting sealing structure for sealing is arranged at the assembly joint 4. The self-adapting sealing structure comprises a self-adapting sealing frame 5 installed outside the assembly joint 4 formed between the two pipe galleries 1. Four sealing plates 6 are arranged inside the self-adapting sealing frame 5. An adjusting screw 7 is rotatably arranged at the top of each sealing plate 6. A guide rod 8 is arranged at the two sides of each adjusting screw 7. The four sealing plates 6 are respectively arranged at the upper, lower, left and right positions of the assembly joint 4 between the two pipe galleries 1. The length of each sealing plate 6 is consistent with the length of the assembly joint 4. One end of each adjusting screw 7 extends to the outside of a corresponding support plate 50, and the adjusting screw 7 is threadedly connected with the corresponding support plate 50. One end of each guide rod 8 is connected with the corresponding sealing plate 6, and the other end extends to the outside of the corresponding support plate 50. The guide rod 8 is slidingly connected with the support plate 50.

[0025] Specifically, in this structure, the adaptive sealing frame 5 is located at the assembly joint 4 after the two pipe racks 1 are assembled. When sealing the four assembly joints 4, the adjusting screw 7 at the corresponding sealing plate 6 can be rotated to move the corresponding sealing plate 6 closer to the corresponding assembly joint 4 and fit against the surface of the assembly joint 4. The plate 6 is then guided to slide outside the guide rod 8. By using the four sealing plates 6 to seal the four assembly joints 4, groundwater can be prevented from entering the interior of the pipe rack 1 from the assembly joint 4 between the two pipe racks 1, thus preventing it from affecting the pipelines inside the pipe rack 1 and further improving the waterproofing effect.

[0026] In a specific embodiment, as shown in the appendix Figure 4 , 5 As shown in Figure 6, the adaptive sealing frame 5 includes four support plates 50. Each support plate 50 has a movable cavity 51 at both ends and on one side of the corresponding guide rod 8. An L-shaped block 52 is provided at one end between every two support plates 50. Movable blocks 53 are provided at both ends of the L-shaped block 52. A movable plate 54 is provided at one end of the movable block 53. Multiple compensating spring plates 55 are provided at one end of the movable plate 54. The movable block 53 at one end of the L-shaped block 52 and the movable block 53 are slidably connected inside the movable cavity 51 of the support plate 50. The two ends of the compensating spring plates 55 are connected to the movable cavity 51 and the movable plate 54, respectively.

[0027] Specifically, in this structure, since the pipe gallery 1 is buried underground, it is prone to thermal expansion and contraction stress caused by the environment. In order to avoid stress being applied to the adaptive sealing frame 5 and affecting the sealing effect of the sealing plate 6, when the pipe gallery 1 experiences stress changes in the up, down, left, and right directions, the corresponding support plate 50 will move, which will cause the movable block 53 and movable plate 54 at the L-shaped block 52 to slide inside the corresponding movable cavity 51 and stretch the compensating spring plate 55. Based on the elasticity of the compensating spring plate 55, the stress on the support plate 50 can be mitigated, thereby achieving the effect of reducing the thermal expansion and contraction stress of the pipe gallery 1 and reducing the impact of stress on the sealing effect of the sealing plate 6.

[0028] Moreover, the adaptive sealing frame 5, through the combined use of the above structure, can be conveniently used for pipe racks 1 of different sizes, thus increasing its application range;

[0029] It is worth noting that, firstly, the movable cavity 51 opened in the support plate 50 is located on one side of the corresponding guide rod 8, which will not affect the sliding guidance of the guide rod 8 on the surface of the support rod. Secondly, the movable cavity 51 opened in the support plate 50 is a T-shaped structure, and when the movable block 53 and the movable plate 54 slide inside the movable cavity 51, it will not cause the movable plate 54 to detach from the inside of the movable cavity 51.

[0030] Working principle of this utility model:

[0031] In actual use, the plurality of pipe galleries 1 are assembled to form a complete pipe gallery 1 system, and assembly gaps are formed between the plurality of pipe galleries 1 after assembly. In order to prevent underground water from entering the interior of the pipe gallery 1 through the assembly gaps, the adjusting screw 7 is rotated to drive the corresponding sealing plate 6 to approach and abut against the surface of the assembly gap 4, and the four sealing plates 6 are used to seal the four assembly gaps 4, so that the underground water is prevented from entering the interior of the pipe gallery 1 through the assembly gaps 4 between the two pipe galleries 1, and the pipelines in the pipe gallery 1 are not affected.

[0032] When the pipe gallery 1 is stressed due to thermal expansion and contraction, the movable block 53 and the movable plate 54 at the corresponding L-shaped block 52 slide in the corresponding movable cavity 51, and the compensation spring sheet 55 is stretched. The elasticity of the compensation spring sheet 55 can alleviate the stress on the support plate 50, so as to achieve the effect of reducing the thermal expansion and contraction stress of the pipe gallery 1, and reduce the influence of the stress of the pipe gallery 1 on the sealing effect of the sealing plate 6.

[0033] The waterproof coiled material 2 is arranged outside each pipe gallery 1, and can prevent the underground water from affecting the concrete pipe gallery 1 and penetrating into the interior of the pipe gallery 1 to affect the pipelines in the pipe gallery 1. The waterproof filling layer 3 filled between the waterproof coiled material 2 and the pipe gallery 1 is elastic waterproof glue, which can not only prevent the underground water from penetrating into the interior of the pipe gallery 1, but also has a certain elastic potential, and can alleviate the thermal expansion and contraction stress of the pipe gallery 1 caused by temperature underground.

[0034] The above only describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
