Description

Technical Field

[0001] This utility model relates to the field of thaw prevention for saline soil roadbeds, specifically a thaw prevention ventilation pipe structure suitable for saline soil roadbeds in seasonally frozen areas. Background Technology

[0002] Saline soil subgrade refers to road subgrades built in saline soil areas. Saline soil is soil with a soluble salt content greater than 0.3% in the topsoil layer at a depth of 1 meter. In road engineering, saline soil can be classified according to its salt content into chloride-saline soil, chlorite-saline soil, sulfite-saline soil, sulfate-saline soil, and carbonate-saline soil. Thawing settlement of saline soil subgrades refers to the phenomenon where, when the temperature drops and the soil freezes, the volume of water freezing increases, causing the soil to expand. To avoid this phenomenon, anti-thaw settlement ventilation pipe structures are needed. The "New Ventilation Pipe for Treating Frost-Heave and Thawing Settlement of Existing Road Subgrades" disclosed in application number "201922222351.8" is an increasingly mature technology. Its "ventilation pipe has inconsistent ventilation diameters at both ends, forming a narrow opening, thus allowing natural air to flow within the pipe. A non-powered fan is installed inside the pipe; under the airflow velocity within the pipe, the non-powered fan rotates, increasing the airflow speed within the pipe; the ventilation pipe is densely covered with drying holes, and the inside of the pipe..." The high-speed airflow carries away unsaturated water from the soil particles surrounding the outer wall of the ventilation duct, reducing the soil moisture content to a level where the soil frost heave rate does not affect the roadbed morphology. However, this ventilation duct has the following drawbacks: While the duct structure, with its narrow ends and non-powered fan, does achieve ventilation and reduce soil moisture content to prevent thawing and settling, the ventilation effect achieved solely through this structure is not significant enough. Therefore, it is necessary to provide a ventilation duct structure that can significantly improve ventilation and drying effects and enhance thawing and settling prevention. Furthermore, this ventilation duct structure is not convenient for extended use as needed, and its installation stability needs improvement. Therefore, it is necessary to provide a ventilation duct structure that is easy to extend and has improved installation stability to enhance versatility. Utility Model Content

[0003] The present invention provides a thawing-resistant ventilation pipe structure suitable for saline soil subgrades in seasonally frozen areas, aiming to solve the problems that the existing ventilation pipe structures are not effective enough in preventing thawing-resistant settlement and are not convenient for extended use as needed.

[0004] To achieve the above objectives, this utility model provides a ventilator structure for preventing thaw settlement of saline soil subgrade in seasonally frozen areas, including a ventilator assembly and a support assembly; The ventilation duct assembly includes a ventilation duct body, ventilation slots at both the upper and lower ends of the ventilation duct body, drainage plates installed inside both the upper and lower ends of the ventilation duct body, extension mechanisms at both ends of the ventilation duct body, fixing plates installed on the inner walls of both ends of the ventilation duct body, mounting brackets fixedly connected inside the fixing plates, ventilation fans on the surface of the mounting brackets, and a drying mechanism installed inside the ventilation duct body.

[0007] As a preferred embodiment of this utility model, two positioning blocks are fixedly connected to both sides of the inner wall of the two ends of the ventilation pipe body, and two positioning grooves are opened on both sides of the fixing plate, with the two positioning blocks being engaged inside the positioning grooves.

[0008] As a preferred embodiment of this utility model, several spiral tubes are fixedly connected at equal intervals on both sides of the ventilation pipe body, and the upper and lower surfaces of the ventilation pipe body are provided with embedding grooves, and the drain plate is installed inside the embedding grooves.

[0009] In a preferred embodiment of this utility model, a bearing is installed inside the ventilation fan, and a rotating shaft is rotatably connected inside the mounting bracket, with the rotating shaft inserted into the bearing.

[0010] As a preferred embodiment of this utility model, two locking blocks are fixedly connected to both the upper and lower ends of the mounting groove, and two slots are opened at both the upper and lower ends of the desiccant, with the two locking blocks locked inside the slots.

Compared with the ventilation duct structure in the existing technology "A novel ventilation duct for treating frost heave and thaw settlement of existing railway subgrade", this utility model can significantly improve the anti-melt settlement performance of the ventilation duct structure through the cooperation of the above structures, thereby enhancing the practicality of the ventilation duct structure.

By sliding two extension strips 1041 at one end of one ventilation pipe body 101 into the strip groove 1042 at one end of another ventilation pipe body 101, several ventilation pipe bodies 101 can be extended as needed, thereby enhancing versatility. At the same time, several hexagonal rods 201 on both sides of the ventilation pipe body 101, together with several supporting nets 202, not only help to prevent melting and settlement, but also increase the contact area with the saline soil subgrade, thereby improving the stability of the ventilation results. When air enters the ventilation pipe... When the main body 101 is in use, the ventilation fan 107 installed inside the ventilation pipe body 101 can initially achieve a ventilation effect when it rotates. The ventilation slots 102 opened on the upper and lower surfaces of the ventilation pipe body 101 can further enhance the ventilation effect on the saline soil subgrade, so as to significantly improve the anti-melting and settling effect. Finally, the tin-material water-draining board 103 can improve the thermal insulation performance, thereby preventing the moisture of the bottom saline soil subgrade from dissolving and causing melting and settling. Finally, the desiccant 1083 installed on both sides of the inner wall of the ventilation pipe body 101 can significantly enhance the drying performance, so as to further improve the anti-melting and settling effect, thereby enhancing the practicality of the ventilation pipe structure.
