Description

Technical Field

[0001] This utility model relates to the field of concrete culvert technology, and in particular to a concrete culvert that reduces water accumulation. Background Technology

[0002] Concrete culverts that reduce water accumulation are underground drainage structures built with concrete. By optimizing the water flow guidance path and enhancing drainage capacity, they can effectively reduce the accumulation of water inside the culvert caused by rainwater and surface runoff. Their core function is to quickly guide water flow, reduce the risk of water retention, and ensure smooth drainage of the culvert and the safety of passage and use in the surrounding area.

[0003] Some culverts are built in low-lying areas, which are prone to water accumulation. When there is too much rainfall, the water level inside the culvert rises quickly, which can easily wash away the walls and cause unnecessary losses.

[0004] An existing patent (publication number: CN214832036U) discloses a concrete culvert for reducing water accumulation, comprising a highway, a roadbed, and a concrete culvert. The concrete culvert is located below the highway. Two sets of backup drainage pipes are fitted to the outer side of the concrete culvert. The outlets of the backup drainage pipes are located outside the roadbed. An inlet is provided at the upper inclined end of each drainage pipe, connecting to a concrete flow channel. The concrete flow channel is inclinedly arranged on the inner wall of the concrete culvert. Fixed pulleys are symmetrically arranged on the inner side of the top of the concrete culvert, and suspension ropes are mounted on the fixed pulleys. This utility model describes a concrete culvert for reducing water accumulation by using backup drainage pipes to solve the problem of rapid water level rise inside the culvert, thus reducing water accumulation. Under normal circumstances, baffles are used to seal the flow channel to prevent debris and animals from entering the pipes and causing blockages. It is suitable for different working conditions and has better application prospects.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing concrete culverts lack effective emergency drainage path designs. When the drainage outlet becomes blocked, water tends to accumulate continuously inside the culvert, making it difficult to drain quickly. Furthermore, there is a lack of graded filtration measures for the water entering the culvert, allowing debris to directly enter the drainage channel, exacerbating the blockage. This makes subsequent maintenance and replacement inconvenient and affects the long-term stable operation of the drainage structure.

[0006] Therefore, a concrete culvert method to reduce water accumulation is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a concrete culvert that reduces water accumulation. This solves the problem that most existing concrete culverts lack effective emergency drainage path design during use. When the drainage outlet is blocked, water tends to accumulate continuously in the culvert and is difficult to drain quickly. At the same time, there is a lack of graded filtration measures for the water entering the culvert, and debris can easily enter the drainage channel directly, leading to more severe blockages. This makes it inconvenient for later maintenance and replacement, and affects the long-term stable operation of the drainage structure.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a concrete culvert for reducing water accumulation, comprising a culvert structure, a water collection tank fixedly connected to the bottom of the culvert structure, a filter mechanism inserted into the inner wall of the culvert structure, anti-water accumulation boxes fixedly connected to the front and rear sides of the culvert structure, a transmission pipe fixedly connected to the bottom of the anti-water accumulation box, the transmission pipe being fixedly connected to the water collection tank on the side near the water collection tank, a pre-filter structure snapped into the inner wall of the water collection tank, the filter mechanism including a mounting frame, inserts fixedly connected to the left and right sides of the mounting frame, the surface of the inserts being inserted into the inner wall of the culvert structure, and a filter screen fixedly connected to the inner wall of the mounting frame.

[0009] Preferably, a filter frame is movably connected to the inner wall of the culvert structure, and a filter assembly is fixedly connected to the inner wall of the filter frame.

[0010] Preferably, the top and bottom of the filter frame are fixedly connected with locking blocks, and the surface of the locking blocks engages with the inner wall of the culvert structure.

[0011] Preferably, the inner wall of the culvert structure is provided with a slot for use with the insert block, and the inner wall of the culvert structure is provided with a water-proof groove.

[0012] Preferably, a filter holder is provided on the top of the water collection tank, and the surface of the filter holder is engaged with the inner wall of the culvert structure.

[0013] Preferably, the inner wall of the culvert structure is movably connected to a drain frame, and the bottom of the drain frame contacts the top of the filter card holder.

[0014] Preferably, the inner wall of the culvert structure is provided with a slot for use with the pre-filter structure, and the inner wall of the culvert structure is provided with a pre-drainage groove.

[0015] Preferably, the bottom of the culvert structure is fixedly connected to a connecting pipe, and the side of the transmission pipe near the water collection tank is fixedly connected to the water collection tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application sets up a filtration mechanism in which the mounting bracket is inserted into the inner wall of the culvert structure via a plug, thereby enabling convenient assembly of the filtration components. The filter screen on the inner wall of the mounting bracket can filter the water flowing into the anti-water accumulation box, reducing the risk of debris entering the transmission pipe and water collection tank and causing blockage, and improving the anti-clogging ability of the overall drainage structure. At the same time, the modular structural design facilitates the maintenance and replacement of the filtration components in the later stage, ensuring long-term use effect.

[0018] 2. This application incorporates a water collection tank at the bottom of the culvert structure, which directly handles water collection and drainage. The pre-filtration structure at the inlet and outlet enables preliminary drainage filtration, reducing the entry of large particles. The anti-accumulation boxes on the front and rear sides are connected to the water collection tank via transmission pipes. When the drainage outlet of the culvert structure becomes blocked, the accumulated water can be discharged through the anti-accumulation boxes and transmission pipes into the water collection tank, effectively preventing the water level inside the culvert structure from rising and ensuring the emergency unobstructed flow of the drainage channel.

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.

[0028] Please see Figure 1-7 The present invention provides the following technical solution:

[0029] A concrete culvert for reducing water accumulation includes a culvert structure 1, a water collection tank 3 fixedly connected to the bottom of the culvert structure 1, a filter mechanism 2 inserted into the inner wall of the culvert structure 1, anti-water accumulation boxes 4 fixedly connected to the front and rear sides of the culvert structure 1, a transmission pipe 5 fixedly connected to the bottom of the anti-water accumulation box 4, the side of the transmission pipe 5 near the water collection tank 3 fixedly connected to the water collection tank 3, a pre-filter structure 6 snapped into the inner wall of the water collection tank 3, and a filter mechanism 2 including a mounting frame 201, inserts 203 fixedly connected to the left and right sides of the mounting frame 201, the surface of the inserts 203 being inserted into the inner wall of the culvert structure 1, and a filter screen 202 fixedly connected to the inner wall of the mounting frame 201.

[0030] In this embodiment: By setting up a filter mechanism 2, the mounting bracket 201 in the filter mechanism 2 is inserted into the inner wall of the culvert structure 1 through the insert block 203, so as to realize the convenient assembly of the filter component 8. The filter screen 202 on the inner wall of the mounting bracket 201 can filter the water flow entering the anti-accumulation box 4, reduce the risk of debris entering the transmission pipe 5 and the water collection tank 3 and causing blockage, and improve the anti-blockage capability of the overall drainage structure. At the same time, the modular structural design facilitates the maintenance and replacement of the filter components in the later stage, ensuring long-term use effect. By setting up the water collection tank 3, the water collection tank 3 at the bottom of the culvert structure 1 can directly undertake the function of water collection and drainage. The pre-filter structure 6 at the inlet and outlet can realize preliminary drainage filtration, reducing the entry of large particles of debris. The anti-accumulation boxes 4 on the front and rear sides are connected to the water collection tank 3 through the transmission pipe 5. When the drainage outlet of the culvert structure 1 is blocked, the accumulated water can be guided into the water collection tank 3 through the anti-accumulation box 4 and the transmission pipe 5 for discharge, effectively preventing the water level in the culvert structure 1 from rising and ensuring the emergency unobstructedness of the drainage channel.

[0031] Specifically, such as Figure 6 As shown, a filter frame 7 is movably connected to the inner wall of the culvert structure 1, and a filter assembly 8 is fixedly connected to the inner wall of the filter frame 7.

[0032] Specifically, such as Figure 6 As shown, the top and bottom of the filter frame 7 are fixedly connected with locking blocks 9, and the surface of the locking blocks 9 is engaged with the inner wall of the culvert structure 1.

[0033] Specifically, such as Figure 7As shown, the inner wall of the culvert structure 1 is provided with a slot 10 for use with the insert block 203, and the inner wall of the culvert structure 1 is provided with a water-proof groove 11.

[0034] In this embodiment: by setting up a filter frame 7 and a filter assembly 8, the filter frame 7 and the culvert structure 1 are movably connected by a locking block 9, which enables quick disassembly and assembly of the filter assembly 8, facilitating daily cleaning and replacement. The filter assembly 8 on the inner wall of the filter frame 7 can perform preliminary filtration of the water flow in the culvert. The slot 10 on the inner wall of the culvert structure 1 is adapted to the insertion block 203 to ensure accurate installation of the filter mechanism 2. The anti-water accumulation groove 11 provides temporary diversion space for accumulated water, which synergistically improves the drainage anti-clogging performance and structural adaptability.

[0035] Specifically, such as Figure 5 As shown, a filter holder 12 is provided on the top of the water collection tank 3, and the surface of the filter holder 12 is engaged with the inner wall of the culvert structure 1.

[0036] Specifically, such as Figure 5 As shown, a drain frame 13 is movably connected to the inner wall of the culvert structure 1, and the bottom of the drain frame 13 contacts the top of the filter card holder 12.

[0037] In this embodiment: by setting up a filter holder 12 and a drain holder 13, when in use, the filter holder 12 is placed on the inner wall of the culvert structure 1, and then the drain holder 13 is placed on top of the filter holder 12, so that the water that can enter the water collection tank 3 can be filtered, avoiding siltation in the water collection tank 3. The dual filtration structure enhances the debris interception capability of the drainage structure and reduces the risk of blockage in the water collection tank 3.

[0038] Specifically, such as Figure 4 As shown, the inner wall of the culvert structure 1 is provided with a slot 14 for use with the pre-filter structure 6, and the inner wall of the culvert structure 1 is provided with a pre-drainage groove 15.

[0040] In this embodiment: the slot 14 opened in the inner wall of the culvert structure 1 facilitates the installation of the pre-filter structure 6 into the inner wall of the culvert structure 1 through the slot 14; the pre-drainage groove 15 opened in the inner wall of the culvert structure 1 facilitates the pre-drainage work of the culvert structure 1 through the pre-drainage groove 15; and the connecting pipe 16 facilitates the transmission of the pre-collected water to the inner wall of the water collection tank 3 through the transmission pipe 5.

[0041] Working principle: During the use of culvert structure 1, a filter mechanism 2 is set up. The mounting bracket 201 in the filter mechanism 2 is inserted into the inner wall of culvert structure 1 through the plug 203, realizing the convenient assembly of the filter component 8. The filter screen 202 on the inner wall of the mounting bracket 201 can filter the water flowing into the anti-accumulation box 4, reducing the risk of debris entering the transmission pipe 5 and the water collection tank 3 and causing blockage, thus improving the anti-blockage ability of the overall drainage structure. At the same time, the modular structure design facilitates the maintenance and replacement of the filter components in the later stage, ensuring long-term use effect. By setting up the water collection tank 3, the water collection tank 3 at the bottom of culvert structure 1 can directly undertake the function of water collection and drainage. The pre-filter structure 6 at the inlet and outlet can achieve preliminary drainage filtration, reducing the entry of large particles of debris. The anti-accumulation boxes 4 on the front and rear sides are connected to the water collection tank 3 through the transmission pipe 5. When the drainage outlet of culvert structure 1 is blocked, the accumulated water can be guided into the water collection tank 3 through the anti-accumulation box 4 and the transmission pipe 5 for discharge, effectively preventing the water level in culvert structure 1 from rising and ensuring the emergency unobstructedness of the drainage channel.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
