Description

Technical Field

[0001] The utility model relates to the technical field of municipal road anti-seepage drainage, in particular to a municipal road anti-seepage drainage structure. Background Art

[0002] Municipal roads refer to expressways, main roads, secondary roads and branch roads. The construction content includes carriageways, pipelines, sidewalks, greening, civil defense, etc. In order to ensure that municipal roads can be used smoothly on rainy days, corresponding drainage ditches are generally built on both sides of the road during construction.

[0003] For example, the Chinese utility model patent with the prior art publication number CN220035100U discloses a municipal road anti-seepage design structure. When the municipal road anti-seepage design structure is used, the buoyancy of rainwater drives the float to float, so that the connecting rod fixedly connected to the middle of the float rises, thereby causing the anti-blocking plate fixedly connected to the other end of the connecting rod to rise, which can lift up the leaves and other debris accumulated on the upper end of the ditch cover, ensure the normal drainage, and avoid the blocks of leaves and other debris on the drain outlet, resulting in a slowdown in drainage, thereby achieving the effect of improving the working efficiency of the anti-seepage design structure.

[0004] However, when the anti-blocking plate rises and leaves the surface of the ditch cover under the action of the float, rainwater flows into the ditch on the road surface, and leaves or other impurities will still flow onto the ditch cover with the flow of water, causing blockage on the ditch cover surface. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-seepage drainage structure for municipal roads, thereby solving the problems mentioned in the above background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A municipal road anti-seepage drainage structure comprises a road surface, a plurality of connecting pipes pre-buried on both sides of the road surface, and a sewer well for connecting two adjacent connecting pipes, wherein the sewer well has an upward opening, a filter frame is provided inside the sewer well, a floating frame is fixedly connected to the top of the filter frame, a filter plate is installed on the inner side of the floating frame, and filter holes are distributed on the surfaces of the filter frame and the filter plate; a gap is provided between the outer peripheral side wall of the filter frame and the well wall of the sewer well, and the sewer well is slidably connected to the well wall near the opening with a sealing frame for sealing the gap, the upper surface of the sealing frame has an inclined surface inclined toward the bottom of the filter frame, and the upper surface of the sealing frame, the well wall of the sewer well and the inclined surface form a ring-shaped water trough.

[0008] Furthermore, the filter holes distributed on the surfaces of the filter frame and the filter plate are all circular through holes.

[0009] Furthermore, a support column is fixedly connected to the bottom of the sewer well, and the top of the support column is fixedly connected with a plurality of cushion blocks for supporting the filter plate.

[0010] Furthermore, a kit sleeved on the support column is fixedly connected to the inner wall of the lower part of the filter frame. The kit includes a sleeve tube slidably connected to the support column and a connecting rod connected between the sleeve tube and the filter frame.

[0011] Furthermore, electric push rods distributed vertically are installed on one pair of opposite well walls of the sewer well. The bottom of the cylinder body of the electric push rod is connected to the well wall of the sewer well, and the telescopic rod part of the electric push rod is connected to the sealing frame.

[0012] Furthermore, a threaded ring is fixedly connected to the well wall of the sewer well near the connecting pipe. A threaded sleeve is threadedly connected in the threaded ring, and a sealing ring is arranged between the threaded sleeve and the pipe orifice of the connecting pipe.

[0013] Furthermore, a waterproof cover is arranged on one side well wall of the sewer well. An inclined plate is connected to the outer wall of the filter frame. The inclined plate is located above the waterproof cover. An electric telescopic rod vertically distributed is fixedly arranged inside the waterproof cover. The telescopic end of the electric telescopic rod extends to the outside of the waterproof cover and is fixedly connected to the inclined plate.

[0014] Furthermore, guide ridges distributed vertically are arranged on the well wall of the sewer well. One end of the inclined plate has a socket slidably connected to the guide ridges, and the other end of the inclined plate is connected to the filter holes distributed on the surface of the filter frame through bolts.

[0015] Compared with the prior art, the utility model provides a municipal road anti-seepage drainage structure, which has the following beneficial effects:

[0016] On the one hand, the filter plate in the floating frame can be used to filter garbage such as leaves in rainwater. And when the road surface rainwater is large and impurities such as leaves block the surface of the filter plate, the buoyancy of water forces the floating frame to rise, thereby realizing the upward lifting of the filter frame. The filter holes around the filter frame are used for draining water and filtering impurities such as leaves in the water flow. And impurities such as leaves in the water flow will float in the upper or middle part of the water flow. Therefore, the filter frame can be used to realize the circulation and collection of the part of the water body in the water flow that does not contain garbage such as leaves, thereby ensuring the smooth collection of sewage and preventing the surface of the filter frame from being blocked.

[0017] On the other hand, by rotating the threaded sleeve, the movement of the threaded sleeve is used to push the sealing ring to move, so that one end of the sealing ring abuts against the pipe orifice of the connecting pipe, and the communication between the connecting pipe and the sewage well can be realized; in addition, by rotating the threaded sleeve in the reverse direction to relieve the extrusion effect on the sealing ring, the separation between the sewage well and the connecting pipe can be realized, and then it is convenient to replace the sewage well.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions of the present invention through detailed embodiments in combination with the drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 4The present embodiment provides an anti-seepage drainage structure for a municipal road, comprising a pavement 1, a plurality of connecting pipes 3 pre-buried on both sides of the pavement 1, and a sewer well 2 for connecting two adjacent connecting pipes 3, the sewer well 2 having an upward opening, a filter frame 6 being provided inside the sewer well 2, a floating frame 9 being fixedly connected to the top of the filter frame 6, a filter plate 10 being installed on the inner side of the floating frame 9, and filter holes being distributed on the surfaces of the filter frame 6 and the filter plate 10; a gap is provided between the outer peripheral side wall of the filter frame 6 and the well wall of the sewer well 2, and the sewer well 2 is slidably connected to a sealing frame 8 for sealing the gap at the well wall near the opening, and the upper surface of the sealing frame 8 has an inclined surface inclined toward the bottom of the filter frame 6, and the upper surface of the sealing frame 8, the well wall of the sewer well 2 and the inclined surface form an annularly distributed water trough, so that rainwater can be gathered in the water trough. The filter plate in the floating frame can be used to filter garbage such as leaves in rainwater. When the rainwater on the road is heavy and impurities such as leaves clog the surface of the filter plate, the buoyancy of the water gathered in the water tank is used to force the floating frame to rise, thereby lifting the filter frame upward. The filter holes around the filter frame are used to drain water and filter impurities such as leaves in the water flow. Impurities such as leaves in the water flow will float in the upper or middle part of the water flow. Therefore, the filter frame can be used to collect the part of the water flow that does not contain garbage such as leaves, thereby ensuring the smooth collection of sewage and will not clog the surface of the filter frame.

[0026] As a preferred embodiment, the filter holes distributed on the surfaces of the filter frame 6 and the filter plate 10 are all circular through holes.

[0027] In some embodiments, reference Figure 3 To prevent damage to the filter plates caused by people stepping on them, support columns 4 are fixedly connected to the bottom of the manhole 2. Several pads 11 are fixedly connected to the tops of these columns to support the filter plates 10. When the floating frame is at its initial height, where the filter plates are at the same height as the manhole's mouth, the support columns and pads ensure that pressure on the filter plates prevents them from being easily damaged. Preferably, the support columns are arranged vertically.

[0028] In some specific embodiments, reference Figure 3 In order to improve the installation stability of the filter frame, the lower inner wall of the filter frame 6 is fixedly connected with a sleeve 5 mounted on the support column 4. The sleeve 5 includes a sleeve slidably connected to the support column and a connecting rod connected between the sleeve and the filter frame.

[0029] In some embodiments, reference Figure 2To facilitate the cleaning of dust and garbage accumulated on the sealing frame, vertically distributed electric push rods 7 are installed on one of the opposite walls of the manhole 2. The bottom of the cylinder of the electric push rod 7 is connected to the wall of the manhole 2, and the telescopic rod of the electric push rod 7 is connected to the sealing frame 8. The sealing frame can be raised to align with the wellhead of the manhole by extending and pushing the electric push rod, so that the garbage accumulated on the sealing frame can be washed away by the water flow, or it can be easily cleaned by personnel.

[0030] In some specific embodiments, the bottom of the cylinder of the electric push rod 7 is connected to the wall of the sewer well 2 by a threaded connection, and the telescopic rod of the electric push rod 7 is connected to the bottom of the sealing frame 8 by a threaded connection, so that it is convenient for personnel to disassemble and assemble the electric push rod.

[0031] In some embodiments, reference Figure 2 To facilitate subsequent replacement of the sewer well, the sewer well 2 is fixedly connected to the well wall near the connecting pipe with a threaded ring 13. A threaded sleeve 14 is internally threadedly connected to the threaded ring 13. A sealing ring 12 is provided between the threaded sleeve 14 and the pipe opening of the connecting pipe 3. By rotating the threaded sleeve, the sealing ring is pushed by the movement of the threaded sleeve, so that one end of the sealing ring presses against the pipe opening of the connecting pipe, thus establishing communication between the connecting pipe and the sewer well. In addition, by rotating the threaded sleeve in the opposite direction to release the squeezing effect on the sealing ring, the sewer well and the connecting pipe can be separated, thus facilitating the replacement of the sewer well.

[0032] In some embodiments, reference Figure 3 and Figure 4 To adapt the filter frame to varying water levels, a waterproof cover 18 is installed on one side of the manhole 2. A sloping plate 16 is connected to the outer wall of the filter frame 6, positioned above the waterproof cover 18. A vertically mounted electric telescopic rod 15 is fixed inside the waterproof cover 18, with the telescopic end of the rod 15 extending outside the waterproof cover 18 and fixedly connected to the sloping plate 16. The waterproof cover prevents water from entering the rod. When the water level is not very high, the buoyancy generated is minimal, allowing the electric telescopic rod to extend and lift the filter frame, thereby raising the sloping plate and assisting in raising the filter frame.

[0033] In some specific embodiments, reference Figure 3 and Figure 4, a guide rib distributed vertically is provided on the well wall of the sewer well 2. One end of the inclined plate 16 has a socket that slidably connects with the guide rib, and the other end of the inclined plate 16 is connected to the filter holes distributed on the surface of the filter frame 6 through bolts 17. Through the sliding fit between the socket and the guide rib, the inclined plate can be made more stable during the up and down movement adjustment. The use of bolts for installation facilitates the detachable connection between the inclined plate and the filter frame.

[0034] Reference Figures 1 to 4 , the working principle of the present utility model is as follows: Sewer wells 2 are embedded on both sides of the road surface 1 according to construction specifications. A connecting pipe 3 is laid between two adjacent sewer wells 2, and a threaded sleeve 14 is used to move and push a sealing ring 12 to move, so that one end of the sealing ring 12 abuts against the pipe orifice of the connecting pipe 3, thereby realizing the connection between the connecting pipe 3 and the sewer well 2; During rainy days, the buoyancy of the water accumulated at the water tank forces the floating frame 9 to rise, thereby realizing the upward lifting of the filter frame 6 (in some other examples, the electric telescopic rod 15 can also be used to assist in lifting the filter frame 6 by extending). The filter holes around the filter frame 6 are used to drain water and filter impurities such as leaves in the water flow. Moreover, impurities such as leaves in the water flow will float in the upper or middle part of the water flow. Therefore, the filter frame can be used to collect the part of the water body in the water flow that does not contain garbage such as leaves, thereby ensuring the smooth collection of sewage and preventing the surface of the filter frame from being blocked.

[0035] It should be noted that the electric push rod and the electric telescopic rod used in the present utility model are conventional products, and their working principles are known public technologies. Their models can be selected according to actual use. External power sources such as commercial power or solar panels can be used for power supply, and corresponding control circuit boards can be set to achieve individual or overall control. The corresponding wiring arrangements and control methods belong to common knowledge, so they will not be elaborated here.

[0036] The above embodiments only exemplarily illustrate the concept and technical solutions of the present utility model, rather than being used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical thought disclosed by the present utility model should still be covered by the claims of the present utility model.

[0037] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative method of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
