Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage, and more specifically, it relates to a road drainage ditch. Background Technology
[0002] Road drainage ditches are linear drainage facilities used to collect and discharge rainwater from the road surface and surrounding areas. They are usually located on both sides of the road or in the central median. Their main functions are to prevent water accumulation on the road surface, protect the road structure, and ensure driving safety.
[0003] Drainage ditches consist of a ditch body and a cover plate located on top of the ditch body. In drainage ditches with relatively low loads, the cover plate rests on the ditch body by its own weight. However, in drainage ditches with higher loads, it is necessary to ensure the overall stability of the cover plate. Therefore, one existing method is to use bolts to connect the cover plate to the ditch body. However, the ditch body needs to be cleaned of debris regularly. Before cleaning the debris, the cover plate needs to be removed. When tightening the fixing bolts, because the bolt holes are filled with mud, people need to clean the mud before loosening the fixing bolts. Each fixing bolt needs to be loosened by cleaning the mud, which makes the operation quite troublesome.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a road drainage ditch.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a road drainage ditch, including a ditch body and several cover plates, wherein two opposing inner walls of the ditch body are integrally formed with support strips, the support strips are recessed downward to form several recessed portions, and threaded holes are provided on the recessed portions; the cover plate includes a main plate and a mounting plate, the mounting plate is provided with mounting holes for communicating with the threaded holes, the two sides of the mounting plate are supported by the recessed portions, the distance from the top surface of the mounting plate to the top surface of the main plate is equal to the thickness of the main plate, and the mounting plate position of the cover plate can be covered by the main plate of another cover plate.
[0007] The present invention is further configured such that: the top surface of the mounting plate has an annular groove, the mounting hole is surrounded in the annular groove, and a sealing strip is installed in the annular groove.
[0008] The present invention is further configured such that the depth of the threaded hole is less than the thickness of the recess.
[0009] The present invention is further configured such that: a circular hole is provided on the mounting plate, and an internal thread is provided on the inner edge of the circular hole; a support plate can be installed on the mounting plate, the thickness of the support plate is equal to the thickness of the main board, and the support plate is fixed to the mounting plate by bolts threaded in the circular hole.
[0010] The present invention is further configured such that: a through hole is provided on the support plate, the position of the through hole corresponds to the position of the mounting hole on the mounting plate, and a plug is engaged in the through hole.
[0011] The present invention is further configured such that: a groove is provided on the top wall of the block, and a pull ring is rotatably connected in the groove, and the pull ring can be flipped out of the groove.
[0012] In summary, this utility model has the following beneficial effects:
[0013] The mounting plate of the cover plate can be covered by the main plate of another cover plate. The recessed part allows the mounting plate to be embedded in the recessed part when the fixing bolts fix the mounting plate in the recessed part. The force applied by the fixing bolts to the cover plate prevents the cover plate from moving up and down along the depth direction of the trench, thus ensuring the overall stability of the cover plate. The upper side of the mounting plate is covered by another cover plate, making it difficult for external soil to enter the mounting hole. Therefore, when people remove the cover plates one by one, they do not need to remove the soil, making it easier to remove the cover plate from the trench. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] Road drainage ditches, such as Figure 1 , Figure 2 and Figure 3As shown, the device includes a trench 1 and several cover plates 2. The cover plates 2 are arranged in a linear array along the length of the trench 1. Supporting strips 3 are integrally formed on two opposing inner walls of the trench 1. Each supporting strip 3 has a recessed portion 4, with threaded holes on the recessed portion 4. Each cover plate 2 includes a main plate 5 and a mounting plate 6. The main plate 5 and mounting plate 6 are integrally formed, and the main plate 5 has several oblong holes. The mounting plate 6 has mounting holes for communicating with the threaded holes. Fixing bolts pass through the mounting holes and are threaded into the threaded holes, thereby fixing the cover plate 2 to the supporting strips 3. The two sides of the mounting plate 6 are supported by the recessed portions 4. The top surface of the mounting plate 6 extends to the top surface of the main plate 5. The distance is equal to the thickness of the mainboard 5. The mounting plate 6 of the cover plate 2 can be covered by the mainboard 5 of another cover plate 2. The recessed part 4 is designed so that when the fixing bolt fixes the mounting plate 6 in the recessed part 4, the mounting plate 6 can be embedded in the recessed part 4. The fixing bolt applies force to the cover plate 2 so that the cover plate 2 cannot move up and down along the depth direction of the trench 1, thereby ensuring the overall stability of the cover plate 2. The upper side of the mounting plate 6 is covered by another cover plate 2, so that external soil is not easy to enter the mounting hole. Therefore, people do not need to remove soil during the process of removing the cover plates 2 one by one, which makes it easier for people to remove the cover plate 2 from the trench 1.
[0021] like Figure 3 and Figure 4 As shown, the top surface of the mounting plate 6 has an annular groove, and the mounting hole is surrounded in the annular groove. A sealing strip 7 is installed in the annular groove. The sealing strip 7 can block the gap between the mounting plate 6 and another cover plate 2, thereby reducing the entry of moisture. The annular groove provides deformation space for the deformation of the sealing strip 7. The depth of the threaded hole is less than the thickness of the recess 4. The lower end of the threaded hole is not connected to the inside of the groove 1, reducing the possibility of water vapor entering the threaded hole from the groove 1.
[0022] like Figure 1 and Figure 4As shown, the mounting plate 6 also has a circular hole 8 with an internal thread along its inner edge. A support plate 9 can be mounted on the mounting plate 6. The thickness of the support plate 9 is equal to the thickness of the main plate 5. The support plate 9 is fixed to the mounting plate 6 by bolts threaded into the circular hole 8. This fixes the thickness difference between the mounting plate 6 and the main plate 5, allowing the mounting plate 6, which is not covered by other cover plates 2, to compensate for the thickness difference through the support plate 9. The support plate 9 has a through hole, the position of which corresponds to the mounting hole on the mounting plate 6. A plug 10 is engaged in the through hole. Block 10 can seal the through hole, preventing soil from entering through the through hole. A groove is provided on the top wall of the block 10, and a pull ring 11 is rotatably connected in the groove. The pull ring 11 can be flipped out of the groove. Several long grooves are provided on the inner peripheral wall of the through hole, and several protrusions are provided on the outer peripheral wall of the block 10 that are embedded in the long grooves. The protrusions increase the friction between the block 10 and the inner peripheral wall of the through hole, making it difficult for the block 10 to separate from the through hole. The pull ring 11 is normally contained in the groove and will not protrude from the surface of the support plate 9. By flipping the pull ring 11, it can be flipped out of the groove, making it easy for people to pull the block 10 out of the through hole.
[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
