Description

Technical Field

[0001] The utility model relates to the technical field of bridge drainage, and more specifically to a bridge drainage hole filter screen which is easy to replace. Background Art

[0002] A bridge is a structure that connects two locations, usually used to cross obstacles such as rivers, roads, and railways. Bridges can be divided into various types, such as beam bridges, arch bridges, cable bridges, etc., each type has its own unique structural characteristics and applicable scenarios. The design and construction of bridges need to consider many factors, such as bearing capacity, durability, aesthetics, etc., to ensure the safety and stability of the bridge. In modern society, bridges play an important role in transportation, greatly facilitating people's travel and the circulation of materials.

[0003] Drain holes are set up on bridges, which are connected to drainage pipes. The drainage holes are designed in two ways: side drainage and vertical drainage. The drainage hole covers are all made of prefabricated cast iron, and the filter hole spacing is 2cm. In the statistical analysis of the causes of water damage over the years, the damage to the centralized drainage pipes that led to the collapse of holes under the bridge, slope protection, drainage channel collapse, and field damage accounted for 65-70%. The reason is that the 2cm drainage hole spacing cannot effectively block the entry of coal slag, gravel, and sand with a diameter of less than 1.5cm. Over time, the drainage pipes are clogged and compacted by debris. The drainage pipes expand and crack during the winter, or the weight of the centralized drainage pipes increases, causing the buckles to fall off, causing the drainage function of the drainage pipes to fail. In addition, due to the small diameter of the drainage holes, the existing silt cannot be removed from the inside. The drainage pipes are easily broken and damaged during the dredging process, and it is easy to cause rainwater on the road surface to fall directly under the bridge through the drainage holes, causing multiple water damage under the bridge. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a bridge drain hole filter that is easy to replace to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a bridge drain hole filter that is easy to replace, comprising a filter barrel, a filter bucket is installed on the top of the filter barrel, circular filter holes are opened on the surfaces of the filter barrel and the filter bucket, and basket holes are opened on the tops of both sides of the filter bucket.

[0006] Furthermore, the filter barrel and the filter bucket are both made of stainless steel, and the side wall thickness of the filter barrel and the filter bucket is 0.1 mm.

[0007] Furthermore, the inner diameter of the circular filter holes is 1 cm, and the distance between two adjacent circular filter holes is 0.8 cm.

[0008] Furthermore, the diameter of the top of the filter bucket is 12 cm, and the diameter of the bottom of the filter bucket and the diameter of the filter barrel are both 6 cm.

[0009] Technical effects and advantages of the utility model:

[0010] The utility model is provided with a filter barrel and a filter bucket. The filter adopts a sinking embedded installation design. The bucket-shaped design of the filter bucket is convenient for installing the filter in the drainage hole of the bridge. It has a good interception effect on debris with larger particles, and prevents debris with larger particles from entering the interior of the drain pipe and causing blockage. When the circular filter holes at the bottom of the filter barrel are blocked by debris such as sediment, rainwater can still be drained through the circular filter holes around the filter barrel and the filter bucket. Combined with regular cleaning, the drainage hole can be effectively prevented from being blocked, so that rainwater can be discharged smoothly through the drainage pipe, effectively preventing water from forming on the bridge surface, and then preventing the drainage pipe from being damaged during the cleaning process. When it is necessary to clean the debris deposited in the filter, the filter can be directly lifted out from the inside of the drainage hole by inserting auxiliary tools into the basket holes on both sides, which is convenient for quickly cleaning the debris.

[0015] Reference Figure 1-Figure 2 The utility model provides a bridge drain hole filter that is easy to replace, including a filter barrel 1, a filter bucket 2 is installed on the top of the filter barrel 1, circular filter holes 3 are opened on the surfaces of the filter barrel 1 and the filter bucket 2, and basket holes 4 are opened on the tops of both sides of the filter bucket 2.

[0016] In the embodiment of the present application, the filter screen in the present application adopts a sunken embedded installation design. The bucket-shaped design of the filter bucket 2 makes it easy to install the filter screen in the drainage hole of the bridge. It has a good interception effect on larger particles of debris, preventing larger particles of debris from entering the interior of the drain pipe and causing blockage. When the circular filter holes 3 at the bottom of the filter barrel 1 are blocked by debris such as sand, rainwater can still be drained through the circular filter holes 3 around the filter barrel 1 and the filter bucket 2. Combined with regular cleaning, the drainage hole can be effectively prevented from being blocked, so that rainwater can be discharged smoothly through the drain pipe, effectively preventing water from gathering on the bridge surface, and then preventing the drain pipe from being damaged during the cleaning process. When it is necessary to clean the debris deposited in the filter screen, the filter screen can be directly lifted out from the inside of the drainage hole by inserting auxiliary tools into the basket holes 4 on both sides, which is convenient for quickly cleaning the debris.

[0017] In a preferred embodiment, the filter barrel 1 and the filter bucket 2 are both made of stainless steel, and the side wall thickness of the filter barrel 1 and the filter bucket 2 is 0.1 mm.

[0018] In a preferred embodiment, the inner diameter of the circular filter hole 3 is 1 cm, and the distance between two adjacent circular filter holes 3 is 0.8 cm, which can intercept and filter larger particles of debris to prevent them from entering the interior of the drain pipe and causing clogging.

[0019] In a preferred embodiment, the diameter of the top of the filter bucket 2 is 12 cm, the diameter of the bottom of the filter bucket 2 and the diameter of the filter barrel 1 are both 6 cm, and the bucket-shaped design of the filter bucket 2 enables the outer side of the filter bucket 2 to fit with the top edge of the drain hole, thereby preventing debris from entering the drain pipe through the gap between the filter and the drain hole.

[0020] Working principle of the utility model: the filter screen in the present application adopts a sinking embedded installation design. The bucket-shaped design of the filter bucket 2 makes it easy to install the filter screen in the drainage hole of the bridge. It has a good interception effect on larger particles of debris, preventing larger particles of debris from entering the interior of the drain pipe and causing blockage. When the circular filter holes 3 at the bottom of the filter barrel 1 are blocked by debris such as sand, rainwater can still be drained through the circular filter holes 3 around the filter barrel 1 and the filter bucket 2. Combined with regular cleaning, the drainage hole can be effectively prevented from being blocked, so that rainwater can be discharged smoothly through the drain pipe, effectively preventing water from forming on the bridge surface, and then preventing the drain pipe from being damaged during the cleaning process. When it is necessary to clean the debris deposited in the filter screen, the filter screen can be directly lifted out from the inside of the drainage hole by inserting auxiliary tools into the basket holes 4 on both sides, which is convenient for quickly cleaning the debris.
