DETAILED DESCRIPTION

[0024] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered below.

[0025] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered below. Figures 1-5 The present application will be further described in detail.

[0026] The embodiments of the present application disclose a highway tunnel construction waterproof drainage structure.

[0027] Referring to Figure 1 and Figure 2 , the highway tunnel 18 construction waterproof drainage structure includes a waterproof plate 19 arranged on the inner wall of the tunnel 18 and a connecting seat 1 located below the waterproof plate 19, and the connecting seat 1 is provided with a drainage groove 2 extending along the extension direction of the tunnel 18; the drainage groove 2 is a hidden channel, and an opening is formed in the connecting seat 1 to communicate with the drainage channel, so that rainwater can flow into the drainage channel, and a filter frame 3 is arranged in the drainage channel below the opening to filter the impurities in the rainwater, and a collecting piece 11 is arranged on one side of the drainage channel to receive the impurities in the filter frame 3, and a lead-out groove 6 is arranged between the filter frame 3 and the collecting piece 11, and the bottom surface of the lead-out groove 6 is inclined downward from the end close to the filter frame 3 to the end away from the filter frame 3. The waterproof plate 19 arranged on the inner wall of the tunnel 18 serves as the first line of defense to prevent groundwater and rainwater from seeping into the interior of the tunnel 18, thereby preventing water from entering the interior through the wall of the tunnel 18. The connecting seat 1 below the waterproof plate 19 is provided with a drainage groove 2 extending along the extension direction of the tunnel 18, which serves as the main drainage channel for rainwater and is designed as a hidden channel to be hidden inside the connecting seat 1, thereby avoiding affecting the appearance and use space of the tunnel 18. The opening formed in the connecting seat 1 allows rainwater to flow into the drainage groove 2, and the collecting piece 11 is arranged on one side of the drainage channel, and the impurities filtered out of the filter frame 3 are guided into the collecting frame 12 through the lead-out groove 6 for storage, and after the rainwater is filtered by the filter frame 3, the clean water flows into the drainage groove 2 through the connecting groove 15 and is finally discharged outside the tunnel 18, and at the same time, the impurities in the filter frame 3 can be washed into the collecting piece 11 by the water flow, and the filter frame 3 itself is not easy to be blocked, thereby avoiding the influence of water accumulation in the tunnel 18 on the structure and driving safety. This design improves the drainage efficiency and reduces the risk of blockage.

[0028] Referring to Figure 3 and Figure 4, the bottom of the filter frame 3 is inclined, and the inclination direction is consistent with the bottom surface of the guide groove 6. In use, rainwater flows into the filter frame 3 after being preliminarily filtered by the ground filter plate 5, and the inclined bottom of the filter frame 3 helps to automatically guide the filtered impurities into the guide groove 6, while the bottom surface of the guide groove 6 is also inclined downward and consistent with the bottom of the filter frame 3. Through the action of the scouring force of the water flow and the inclination angle, the impurities will flow smoothly from the filter frame 3 to the guide groove 6 and finally into the collection frame 12 in the collection piece 11, thereby avoiding excessive accumulation of impurities in the filter frame 3 and ensuring the smoothness and efficiency of the drainage system. The use of this structural design does not require complex operations, and relies on the inclination design and the natural drainage of impurities by water flow. During maintenance, only the impurities in the collection frame 12 need to be cleaned regularly, reducing the frequency of manual cleaning of the filter frame 3 and prolonging the service life of the drainage system.

[0029] The top of the filter frame 3 is provided with a ground filter plate 5, and the ground filter plate 5 is provided with a water inlet. The connecting seat 1 is provided with a groove 4 around the opening, and the ground filter plate 5 is connected with the groove 4. The water inlet on the ground filter plate 5 is used to guide rainwater into the filtering system and preliminarily filter large impurities in the rainwater to prevent these impurities from directly entering the filter frame 3 and reducing the pressure on the subsequent filtering system. The groove 4 is connected with the ground filter plate 5 around the opening of the connecting seat 1, and the ground filter plate 5 is fixed by clamping to ensure that it remains stable during use and does not shift or loosen due to water flow impact or other external forces. In use, rainwater first flows into the ground filter plate 5 through the water inlet, and the ground filter plate 5 preliminarily filters large particles in the water. The rainwater filtered by the ground filter plate 5 enters the filter frame 3 for further filtering. The advantage of this structural design is that it can ensure the stability and filtering effect of the drainage system, and because the ground filter plate 5 is connected with the groove 4 by clamping, the ground filter plate 5 is very easy to install and remove, and only needs to be removed from the groove 4 when cleaning or replacement is required.

[0030] The water inlet on the ground filter plate 5 is in a long strip shape and is provided in parallel with multiple. The long strip-shaped water inlet can allow more rainwater to pass through the ground filter plate 5 in a shorter period of time, reducing water retention and water accumulation, and ensuring smooth drainage in the tunnel 18. In addition, the parallel arrangement of multiple long strip-shaped water inlets helps to evenly distribute the water flow pressure and avoid excessive water pressure at a certain position, thereby reducing the risk of local blockage.

[0031] Referring to Figure 5The connecting piece 7 is provided between the ground filter plate 5 and the filter frame 3, and comprises a threaded stud 8, a nut 9 and a clamping seat 10 provided on the side wall of the ground filter plate 5 and the filter frame 3. The top end of the threaded stud 8 is rotatably arranged on the clamping seat 10 of the ground filter plate 5, the bottom of the threaded stud 8 is clamped into the clamping seat 10 of the filter frame 3, and the nut 9 is connected with the threaded stud and is pressed on the clamping seat 10 of the filter frame 3. The connecting piece 7 is used to tightly connect the ground filter plate 5 and the filter frame 3, so that the rainwater filtered by the ground filter plate 5 can smoothly enter the filter frame 3 for further impurity filtration, and the rainwater will not flow out or the impurities will not enter the untreated area due to loose structure. When maintenance or replacement of the filter frame 3 is needed, the user only needs to unscrew the nut 9, so that the threaded stud 8 is separated from the clamping seat 10 of the filter frame 3, and then the filter frame 3 can be easily removed for cleaning or replacement. After the new filter frame 3 is replaced, the threaded stud 8 is clamped into the clamping seat 10 of the filter frame 3, and the nut 9 is tightened, so as to ensure that the ground filter plate 5 and the filter frame 3 are tightly combined again.

[0032] The connecting seat 1 is provided with a recess 13 for mounting the collecting piece 11, and the bottom of the recess 13 is provided with a connecting groove 15 connected with the drainage channel. The recess 13 is used to provide a fixed position for the collecting piece 11, so as to ensure that the collecting piece 11 can stably receive the impurities discharged through the guide-out groove 6 during the drainage process. This design can avoid the dispersion of impurities, ensure that the impurities are concentrated in the collecting frame 12, and facilitate subsequent cleaning and maintenance. The connecting groove 15 at the bottom of the recess 13 is connected with the drainage channel, and the connecting groove 15 is used to allow the impurities to be deposited in the collecting frame 12, while any excess water can smoothly flow into the drainage channel and then be discharged from the tunnel 18, so as to prevent water from accumulating in the recess 13 or the collecting piece 11, thereby preventing the system from being blocked or reducing the drainage efficiency.

[0033] The collecting piece 11 comprises a collecting frame 12, and the side wall of the collecting frame 12 is provided with a slot 14 matched with the bottom end of the guide-out groove 6, and the bottom wall of the collecting frame 12 is provided with a through hole corresponding to the connecting groove 15. The slot 14 on the side wall is matched with the bottom end of the guide-out groove 6, so that the impurities discharged from the filter frame 3 can smoothly enter the collecting frame 12 through the guide-out groove 6, thereby ensuring that the impurities are concentrated in the collecting frame 12 for collection and storage, and preventing the impurities from scattering or blocking other drainage parts. In this way, after passing through the filter frame 3 and the guide-out groove 6, the impurities are concentrated and collected in the collecting frame 12, thereby facilitating regular cleaning. The through hole in the bottom wall of the collecting frame 12 is connected with the connecting groove 15, and the through hole is used to ensure that the excess water can flow into the connecting groove 15 through the through hole during the collection of the impurities, and then be discharged into the drainage channel, thereby preventing water from accumulating in the collecting frame 12. This design ensures that even if the impurities are effectively collected, the drainage function is still smooth.

[0034] The top wall of the collecting frame 12 is bolted with a cover plate 16, and the inner side wall of the collecting frame 12 is provided with a handle 17. The cover plate 16 serves to provide a sealed protection for the collecting frame 12, preventing impurities from overflowing or scattering to the external environment during the operation of the drainage system, and avoiding external objects from entering the collecting frame 12, affecting the centralized collection of impurities and the drainage function. The cover plate 16 is fixed by bolts, ensuring stability and not easy to shift during use. When cleaning is needed, the bolts can be easily loosened to remove the cover plate 16. The handle 17 provided on the inner side wall greatly facilitates the disassembly and cleaning operation of the collecting frame 12. When regular maintenance is needed, the staff can easily extract the collecting frame 12 through the handle 17, avoiding direct contact with the impurities inside, improving the convenience and hygiene of the operation.

[0035] The bottom surface and the side surface of the filtering frame 3 are both provided with filtering holes. The filtering holes on the bottom surface and the side surface of the filtering frame 3 help to quickly drain the filtered water, avoiding the water flow from staying in the filtering frame 3 for too long, thereby improving the drainage speed and ensuring that the entire system can cope with larger water flow.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. 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.
