Description

Technical Field

[0001] The utility model relates to the technical field of box beams, and more specifically, to a prefabricated box beam which is convenient to maintain. Background Art

[0002] Box girder bridge is a type of bridge. It is composed of multiple box girders. It is easy to construct and can be easily seen in daily life.

[0003] On rainy days, the bridge surface blocks the bottom, causing rainwater in the area to gather on the bridge deck. In order to avoid rainwater accumulation affecting traffic, drainage structures are now set up on the bridge to reduce the probability of water accumulation.

[0004] However, when the bridge is in use, garbage will inevitably be generated on the bridge deck. On rainy days, the garbage will enter the drainage structure with rainwater, causing internal blockage. The drainage structure is currently filtered to reduce the blockage caused by garbage in the drainage structure.

[0005] However, garbage will still clog the filter. When the blockage reaches a certain level, the drainage structure cannot drain water, which can easily cause water accumulation.

[0006] This application provides another technical solution to this technical problem. Utility Model Content

[0007] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a prefabricated box girder that is convenient to maintain.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0009] A prefabricated box girder with convenient maintenance comprises a main beam and side guards extending on both sides, a drainage groove is formed near the side guards on the main beam, a drainage outlet is opened in the drainage groove, a filter plate is installed at the opening of the drainage groove, the filter plate is movably connected to the main beam through a connecting piece, and the filter plate is provided with a storage piece for collecting garbage.

[0010] The utility model is further configured as follows: the connecting member comprises a rotating shaft, and the filter plate is rotatably connected to the main beam via the rotating shaft.

[0011] The utility model is further configured as follows: the rotating shaft is located in the middle of the filter plate, a counterweight is fixedly installed on the edge of the filter plate facing the inner side of the drainage trough and close to the retaining edge, and the edge of the filter plate away from the retaining edge is in contact with the main beam through the gravity of the counterweight.

[0012] The utility model is further configured as follows: the storage member comprises a storage net located in the drainage groove, and the storage net is detachably connected to the filter plate and the side wall of the drainage groove.

[0013] The utility model is further configured as follows: the filter plate and the side wall of the drainage trough are both fixedly connected with hooks for hanging the storage net.

[0014] The utility model is further configured as follows: the filter plate is formed with a plurality of filter ports.

[0015] In summary, the utility model has the following beneficial effects:

[0016] The garbage on the surface of the main beam flows to the filtration point with the rainwater. After the rainwater passes through the filter plate and enters the drainage trough, it is discharged through the drain outlet. The garbage is located on the surface of the filter plate due to the obstruction of the filter plate. When the weight of the garbage is greater than the counterweight block, the filter plate will rotate, and the garbage will slide along the filter plate to the collection net in the drainage trough. The collection net collects the garbage, reducing the garbage on the surface of the filter plate, reducing the impact of garbage on the speed of rainwater passing through the filter plate, and reducing the probability of water accumulation.

[0017] Because the garbage collection net is located in the drain trough, it can withstand more garbage than the direct filtration of the existing filter plate, further reducing the probability of water accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] like Figure 1 and Figure 2As shown, the present application provides a prefabricated box girder which is convenient for maintenance, including a main beam 1 and side guards 2 extending on both sides. A drainage trough 3 is formed near the side guard 2 on the main beam 1, and a drainage port 4 is opened in the drainage trough 3. The drainage port 4 is connected to the drainage pipe of the surrounding drainage system. The surface of the main beam 1 has a certain curvature. When it rains, rainwater will flow along the surface of the main beam 1 to the two sides of the main beam 1 and enter the drainage trough 3. After being collected in the drainage trough 3, it will be discharged through the drainage port 4 and the drainage pipe. A filter plate 5 is installed at the opening of the drainage trough 3. The filter plate 5 will block the opening of the drainage trough 3. The filter plate 5 is formed with a plurality of filter ports. Water will be directly discharged into the drainage trough 3 through the filter ports. The filter plate 5 will filter the rainwater so that garbage cannot directly enter the drainage trough 3, so that garbage cannot cause blockage in the drainage trough 3.

[0023] like Figure 2 As shown, a connecting member is provided between the filter plate 5 and the main beam 1, and the connecting member includes a rotating shaft, through which the filter plate 5 is rotatably connected to the main beam 1, wherein a counterweight 6 is fixedly installed on the edge of the filter plate 5 facing the inner side of the drainage trough 3 and close to the retaining edge 2, and the counterweight 6 causes the filter plate 5 to rotate. In the initial state, the edge of the filter plate 5 away from the retaining edge 2 is abutted against the main beam 1 by the gravity of the counterweight 6, thereby ensuring that the filter plate 5 blocks the opening of the drainage trough 3 at this time.

[0024] like Figure 2 As shown, the filter plate 5 and the side wall of the drainage trough 3 are fixedly connected with a hook 7, and the filter plate 5 is provided with a storage component, which includes a storage net 8 located in the drainage trough 3. The storage net 8 can be hung on the hook 7 to achieve the connection between the filter plate 5 and the side wall of the drainage trough 3.

[0025] The garbage on the surface of the main beam 1 flows to the filtration point with the rainwater. After the rainwater passes through the filter plate 5 and enters the drainage trough 3, it is discharged through the drain port 4. Due to the obstruction of the filter plate 5, the garbage will be located on the surface of the filter plate 5 and away from the retaining edge 2. When the weight of the garbage is greater than the counterweight block 6, the filter plate 5 will rotate, and the garbage will slide along the filter plate 5 to the receiving net 8 in the drainage trough 3. The receiving net 8 collects the garbage, reduces the garbage on the surface of the filter plate 5, reduces the impact of the garbage on the speed of rainwater passing through the filter plate 5, and reduces the probability of water accumulation. Compared with the direct filtration of the existing filter plate 5, the garbage can withstand more garbage due to the receiving net 8 in the drainage trough 3, further reducing the probability of water accumulation. At the same time, such a design is convenient for the subsequent cleaning of the garbage entering the drainage trough 3, thereby improving the efficiency of maintenance and cleaning.

[0026] In summary, the box beam provided in this embodiment reduces the influence of garbage on the speed of rainwater passing through the filter plate 5, increases the garbage that the drainage structure can withstand, and thus reduces the probability of water accumulation.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
