Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage in rail transit engineering, and particularly relates to a novel cover plate arranged above a drainage ditch in a vehicle depot. Background Technique

[0002] A drainage ditch refers to a ditch that diverts the water collected from a side ditch, a catch ditch, and low-lying areas near a roadbed, in a crop field, or near a residence to a ditch outside the roadbed, crop field, or residence. The design of the drainage ditch determines the depth and spacing of the field drainage ditches according to the layout and engineering standards of the drainage system project, and analyzes and calculates the flow rate, water level, cross-sectional dimensions, and engineering quantities of each level of drainage ditches and buildings.

[0003] There are still some deficiencies in the existing drainage ditches during use. The conventional cover plates arranged above the drainage ditches generally adopt concrete materials, and holes are opened on the plates to allow sewage and wastewater to flow into the drainage ditches. Such cover plates are heavy, and it is difficult to ensure the uniformity of the aperture and hole spacing of the opened holes, whether they are too large or too small; the conventional cover plates easily cause other sundries to flow into the drainage ditch along with the sewage and wastewater, resulting in a smaller drainage cross-section of the drainage ditch or even blockage, which does not conform to the design concept of green environmental protection.

[0023] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment, please refer to Figures 1-5 , the present utility model provides a technical solution:

[0025] A new type of cover plate arranged above the drainage ditch in the vehicle base, including a drainage ditch 5. A first embedded angle steel 6 is fixedly connected to the top of the drainage ditch 5. A main body of stainless steel cover plate 1 is fixedly connected to the top of the first embedded angle steel 6. A second embedded angle steel 7 is fixedly connected to the side of the main body of stainless steel cover plate 1. A removable top plate 4 abuts against the top of the second embedded angle steel 7. A gasket 8 is fixedly connected to the side of the main body of stainless steel cover plate 1. A welding point 9 is fixedly connected to the outer surface of the gasket 8. A stainless steel filter net with perforated mesh 2 is fixedly connected to the side of the gasket 8. A water passing hole on the top plate 3 is fixedly connected to the top of the removable top plate 4.

[0026] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3As shown, the shapes of the first embedded angle steel 6 and the second embedded angle steel 7 are both L-shaped. The materials of the first embedded angle steel 6 and the second embedded angle steel 7 are both stainless steel. The sizes of the first embedded angle steel 6 and the second embedded angle steel 7 are the same. There are multiple top plate water holes 3, and the multiple top plate water holes 3 are evenly distributed in the detachable top plate 4. The sizes of the multiple top plate water holes 3 are the same. The shape of the detachable top plate 4 is rectangular, and the material of the detachable top plate 4 is stainless steel.

[0027] Among them, larger sundries in the sewage and wastewater can be blocked on the top plate to form the first barrier. At the same time, smaller sundries in the sewage and wastewater can be blocked by the perforated stainless steel filter screen 2 to form the second barrier. Basically, more than 95% of the sundries in the sewage and wastewater can be intercepted, the operation and maintenance interval is extended, and the sundries in the sewage and wastewater can be effectively separated, facilitating the operation and maintenance personnel to clean and remove the sundries at the cover plate.

[0028] In this embodiment, as Figure 4 and Figure 5 shown, the perforated stainless steel filter screen 2 is arranged at the bottom of the top plate water hole 3. The shape of the perforated stainless steel filter screen 2 is rectangular. The drainage ditch 5 is arranged at the bottom of the top plate water hole 3 and the perforated stainless steel filter screen 2. The shape of the drainage ditch 5 is rectangular. The welding point 9 is fixedly connected to the center of the side surface of the gasket 8. The shape of the welding point 9 is circular. The detachable top plate 4 is arranged on the top of the perforated stainless steel filter screen 2. The detachable top plate 4 is arranged at the bottom of the top plate water hole 3.

[0029] Among them, since most of the sundries have been effectively intercepted by the new cover plate, the drainage ditch 5 can basically be "cleaned zero". In extreme cases, if the drainage ditch 5 is blocked by sundries, the maintenance personnel only need to remove the entire new cover plate. After investigation, the new cover plate of the same size is about 90% of the weight of the traditional concrete cover plate. Made of stainless steel, it has good corrosion resistance, extends the service life, extends the maintenance interval, and has certain economic benefits.

[0030] Workflow of the utility model: When the new cover plate, which is designed according to this solution and is arranged above the drainage ditch in the vehicle depot, is in operation, the new cover plate is completed in the factory according to the design drawings, and the manufactured new cover plate is transported to the construction site; it is neatly stacked in the on-site storage yard and corresponding protection measures are taken. After the concrete construction of the side wall of the drainage ditch 5 is completed, angle steel is installed according to the design drawings, and measurement and positioning are carried out according to the design drawings. After the positioning is completed, the new cover plate is installed directly above the drainage ditch 5, and the height of the completed surface of the cover plate is calibrated with the height of the civil engineering decoration surface to meet the design requirements. By evenly arranging the top plate water holes 3 above the detachable top plate 4, larger debris in the sewage and wastewater can be blocked on the top plate, forming the first barrier; by setting the stainless steel filter screen 2 with hole meshes (the size of the hole meshes can be adjusted according to different usage places) on the stainless steel cover plate main body 1, smaller debris in the sewage and wastewater can be blocked on the stainless steel filter screen 2 with hole meshes, forming the second barrier. After the above measures, more than 95% of the debris in the sewage and wastewater can be intercepted basically, which extends the operation and maintenance interval. During the operation and maintenance period, the staff can directly clean the larger debris above the detachable top plate 4. After the cleaning is completed, the detachable top plate 4 is removed, and the smaller debris above the stainless steel filter screen 2 with hole meshes is cleaned. Since the new cover plate has effectively intercepted most of the debris, the drainage ditch 5 can be basically "cleaned zero". In extreme cases, if the drainage ditch 5 is blocked by debris, the maintenance personnel only need to remove the entire new cover plate. After investigation, the new cover plate of the same size is about 90% of the weight of the traditional concrete cover plate.

[0031] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
