Description

Technical Field

[0001] The utility model relates to a municipal building structure, in particular to a road manhole cover structure, specifically to an invisible manhole cover structure which can effectively deal with the situation that a lane manhole cover occupies a sidewalk. Background Art

[0002] In municipal road construction, when there are both a driveway and a sidewalk, the sidewalk is usually higher than the driveway. At the same time, there are often multiple manhole covers on the driveway, and it is common to encounter situations where the manhole covers on the driveway intrude into the sidewalk. Moreover, the manhole covers on the driveway must be openable for maintenance.

[0003] At present, the conventional construction method is to cut off the part of the sidewalk occupied by the driveway manhole cover, and then make the sidewalk curb into an arc shape that is compatible with the driveway manhole cover. In this way, although the problem of subsequent opening of the driveway manhole cover can be solved, it also causes multiple notch-shaped pits on the sidewalk, which not only destroys the beauty of the sidewalk, but also makes it easy for pedestrians to fall, posing a great safety hazard.

[0004] Therefore, it is urgently needed to be improved in order to better meet the market demand. Utility Model Content

[0005] The purpose of the utility model is to address the problem of driveway manhole covers encroaching on sidewalks currently encountered in municipal road construction, and to provide an invisible manhole cover structure that effectively deals with the situation of driveway manhole covers encroaching on sidewalks. On the premise of fully meeting the normal use of the driveway manhole covers, the problem of digging holes in the sidewalks in the past is avoided, the integrity and aesthetics of the sidewalks are maintained, and the risk of pedestrians falling is eliminated, fully meeting the needs of the market.

[0006] The technical solution of the utility model is:

[0007] An invisible manhole cover structure which can effectively deal with the situation where a driveway manhole cover encroaches on a sidewalk, comprises a placement groove and a cover plate. The placement groove is a "凵"-shaped groove which is arranged on the sidewalk and covers the area where the driveway manhole cover encroaches on the sidewalk, with its opening facing the driveway and its bottom surface being higher than and avoiding the driveway manhole cover. The cover plate is block-shaped and cooperates with the placement groove. It can be movably arranged in the placement groove and covers the part where the driveway manhole cover encroaches on the sidewalk in the air.

[0008] Furthermore, the inner side edge of the bottom surface of the placement groove is arc-shaped, which is compatible with the lane manhole cover.

[0009] Furthermore, the cover plate is in the shape of a rectangular box with a bottom but no top, and concrete or sidewalk paving materials are poured inside the cover plate.

[0010] Furthermore, reinforcement is provided inside the cover plate.

[0011] Further, handles are provided at the four corners of the cover plate.

[0012] Further, a limit frame is further included, which is a "U"-shaped frame made of steel strip, and its size is adapted to the cover plate. The longitudinal section of its side is an L-shaped bent inward; the limit frame surrounds the cover plate and is embedded between the cover plate and the placement groove, and its opening faces the lane.

[0013] Further, both ends of the limit frame are bent inward into a right-angled L-shape to prevent the cover plate from moving towards the lane direction.

[0014] Further, the distance between the side and the end of the limit frame from the edge of the lane manhole cover is not less than 50 mm.

[0015] Advantages of the utility model:

[0016] The utility model is reasonably designed and has a simple structure. On the premise of fully meeting the normal use of the lane manhole cover, it avoids the previous practice of digging pits on the sidewalk. It not only maintains the integrity and beauty of the sidewalk, but also eliminates the potential risk of pedestrians falling. At the same time, it also facilitates the property management unit to open the lane manhole cover, fully meeting the market demand. Brief description of the drawings

[0020] The following further describes the utility model in conjunction with the drawings and embodiments.

[0021] As Figure 1 and Figure 2 shown.

[0022] An invisible manhole cover structure for effectively dealing with the situation where the lane manhole cover encroaches on the sidewalk includes a placement groove 4, a cover plate 6, a limit frame 5, etc.

[0023] The placement groove 4 is a "U"-shaped groove, which is arranged on the sidewalk and covers the area where the lane manhole cover 1 encroaches on the sidewalk 3. Its opening faces the lane, and its bottom surface is higher than and avoids the lane manhole cover 1, facilitating the subsequent installation of the cover plate 6 and the opening of the lane manhole cover 1. Preferably, the bottom surface of the placement groove 4 near the side of the lane manhole cover 1 is arc-shaped to ensure the support strength and be more beautiful.

[0024] The cover plate 6 is a rectangular box with a bottom but no top, made of stainless steel, and its size matches the placement slot 4, and can be movably arranged in the placement slot 4. Reinforcement 8 is provided on the bottom surface inside the cover plate 6, and concrete or sidewalk paving materials are poured inside the cover plate 6 to give it sufficient strength and coordinate with the sidewalk 3. Preferably, handles 7 are provided at the four corners of the cover plate 6 to facilitate the installation or removal of the cover plate 6 by pulling. The handle 7 is a purchased product and is round, with a hidden steel chain inside. At the same time, the reinforcement 8 is made of threaded steel bars and arranged in a fishbone shape. The diameter of the steel bar is about 10 mm, and the spacing is about 15 cm.

[0025] The limit frame 5 is a "凵"-shaped frame made of stainless steel strip, and its size is adapted to the cover plate 6. It is placed in the placement groove 4, and its opening faces the lane 2. Then, the cover plate 6 can be placed in the limit frame 5, making the installation of the cover plate 6 more convenient. Preferably, the longitudinal section of the side of the limit frame 5 is an L-shape bent inward, so that the cover plate 6 can be placed on the bottom edge of the side of the limit frame 5 to enhance its supporting strength. At the same time, the two ends of the limit frame 5 are respectively bent inward into a right-angle L-shape, and are flush with the curbstone of the sidewalk 3, which can prevent the cover plate 6 from moving in the direction of the lane 2. The side and end of the limit frame 5 are not less than 50 mm away from the edge of the lane manhole cover 1, which is convenient for the subsequent opening of the lane manhole cover.

[0026] During new construction, first measure the size of the lane manhole cover intruding into the sidewalk, and reserve an area for the placement slot accordingly. During renovation construction, it is necessary to cut a placement slot that can accommodate the limit frame according to the size of the lane manhole cover intruding into the sidewalk. Then, according to the height of the cover plate, the bottom surface of the placement slot is leveled with concrete, and the side adjacent to the lane manhole cover is arc-shaped. Then, place the stainless steel limit frame and cover plate in the placement slot. The limit frame and cover plate are pre-customized, and reinforcement and handles are pre-set in the cover plate. Finally, pour permeable concrete or lay floor tiles in the cover plate, flush with the top of the sidewalk, so that it covers the part of the lane manhole cover intruding into the sidewalk in the air. At the same time, build or repair the sidewalk outside the limit frame.

[0027] The utility model can avoid the previous practice of digging holes in the sidewalk while fully meeting the normal use of the driveway manhole cover, which not only maintains the integrity and aesthetics of the sidewalk, but also eliminates the risk of pedestrians falling. At the same time, it also facilitates the property rights unit to open the driveway manhole cover, fully meeting the market demand.

[0028] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
