Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to an invisible manhole cover with strong bearing capacity. Background Art

[0002] Manhole covers are used to cover deep wells on roads to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes and other places. As people's requirements for the aesthetics of roads gradually increase, more and more hidden manhole covers are developed and put into use. This not only increases the aesthetics of the road, but also improves the comfort of people when driving and walking on the road.

[0003] 1. Safety hazards

[0004] Manhole covers are displaced or missing: In some areas, manhole covers may be displaced or missing due to loose installation or damage by external forces. This not only poses a risk of falling to pedestrians, but may also cause vehicles to get stuck or be damaged, seriously affecting traffic safety.

[0005] 2. Substandard quality of manhole covers: Some manhole covers are manufactured with shoddy workmanship and inferior materials, resulting in low load-bearing capacity and easy damage. Such manhole covers are prone to breakage and collapse during use, posing a safety threat to pedestrians and vehicles.

[0006] 2. Poor management

[0007] 1. Unclear markings on manhole covers: Some manhole covers are not clearly marked with information such as their functions, management departments, or contact numbers, resulting in the inability to contact relevant departments in a timely manner for processing when problems arise with the manhole covers.

[0008] 2. Inadequate inspection of manhole covers: Some areas do not pay enough attention to the inspection of manhole covers, resulting in the failure to timely discover and deal with problems with manhole covers. This may cause the problems of manhole covers to gradually worsen and increase safety hazards.

[0009] 3. Unreasonable design

[0010] 1. The size of the manhole cover is not suitable: the size of some manhole covers does not match the wellhead, resulting in the manhole cover being loose and loose. This not only affects the sealing of the manhole cover, but may also cause the manhole cover to shift or be missing.

[0011] 2. Improper manhole cover material: The manhole cover material in some areas does not meet the use requirements, such as using non-corrosion-resistant materials or materials that are easily affected by temperature. Such manhole covers are prone to rust and deformation during use, affecting their service life and safety performance.

[0012] IV. Environmental Issues

[0013] 1. Manhole cover noise pollution: Some manhole covers will generate loud noise when vehicles or pedestrians pass by, causing interference to the lives of surrounding residents.

[0014] 2. Manhole covers affect the beauty of the environment: The design or color of some manhole covers is not in harmony with the surrounding environment, affecting the beauty of the city's environment. Utility Model Content

[0031] The present utility model will be further described below with reference to the accompanying drawings.

[0032] As Figure 1-2 shown, the present utility model discloses a stealth manhole cover with较强 bearing capacity, including: an outer frame 1 and an inner frame 2 whose outer wall is attached to and slidably connected to the inner wall of the outer frame 1. A boss 11 is circumferentially provided at the lower part of the inner wall of the outer frame 1. A shock-absorbing pad 12 is circumferentially provided at the top end of the boss 11 along the inner wall of the outer frame 1. The bottom end of the inner frame 2 is fixedly connected to a bottom plate 21 whose outer wall is attached to and slidably connected to the inner wall of the boss 11. A receiving groove 22 is formed between the outer wall of the bottom plate 21 and the bottom end of the inner frame 2. The width of the inner wall of the receiving groove 22 is equal to the width of the cross section of the shock-absorbing pad 12. A reinforcing rib array 23 is fixedly provided at the bottom end of the inner wall of the inner frame 2. A concrete layer 3, a mortar layer 4 and a paving panel layer 5 are sequentially filled in the inner frame 2 from bottom to top. The paving panel layer 5 uses a corresponding style according to the installation environment.

[0033] Based on the above structure, as Figure 1-2As shown, when in use, the inner frame 2 is covered inside the outer frame 1, and the boss 11 provides an upward supporting force for the inner frame 2, so that the top of the inner frame 2 is parallel to the top of the outer frame 1, and at the same time, the inner frame 2 is prevented from sliding down. The setting of the shock-absorbing pad 12 increases the buffering effect when the inner frame 2 and the outer frame 1 are covered, thereby preventing the bottom end of the inner frame 2 and the top end of the boss 11 from being damaged due to collision. At the same time, the shock-absorbing pad 12 can effectively absorb and disperse the impact force or vibration from the outside, thereby improving the stability of the overall structure and avoiding the problem of noise pollution. The setting of the reinforcement rib array 23 can effectively improve the bearing capacity of the inner frame 2, thereby enhancing the load-bearing capacity, stability and durability of the entire structure. While ensuring the structural safety, the setting of the paving panel layer 5 also takes into account the aesthetics of the building, meeting the dual needs of practicality and aesthetics.

[0034] Further, such as Figure 1-2 As shown, the reinforcing bar array 23 is composed of a plurality of steel bars uniformly arranged in the transverse and longitudinal directions.

[0035] Further, such as Figure 3 As shown, in order to further increase the load capacity, the reinforcement rib array 23 is a cross-shaped steel frame, and the load capacity of the cross-shaped steel frame is 125KN, which is suitable for sidewalks, non-motorized vehicle lanes, car parking lots and underground parking lots.

[0036] Further, such as Figure 4 As shown, in order to further increase the load capacity, the reinforcement rib array 23 is a M-shaped steel frame, and the load capacity of the M-shaped steel frame is 125KN, which is suitable for sidewalks, non-motorized vehicle lanes, car parking lots and underground parking lots.

[0037] Further, such as Figure 5 As shown, in order to further increase the load capacity, the reinforcement rib array 23 is a "F"-shaped steel frame, and the load capacity of the "F"-shaped steel frame is 125KN, which is suitable for sidewalks, non-motorized vehicle lanes, car parking lots and underground parking lots.

[0038] Further, such as Figure 6 As shown, in order to further increase the load capacity, the reinforcement rib array 23 is a tic-tac-toe steel frame, and the load capacity of the tic-tac-toe steel frame is 250KN, which is suitable for residential areas, back streets and alleys, and areas where only light motor vehicles or small cars travel.

[0039] Further, such as Figure 1-6 As shown, in order to further increase the load capacity, a reinforcing rib frame 24 integrated with the reinforcing rib array 23 is fixedly provided at the bottom end of the inner wall of the inner frame 2 .

[0040] Further, such as Figure 1-5As shown, in order to facilitate the installation and disassembly of the inner frame, a triangular plate 25 is provided at the four corners of the top of the inner wall of the inner frame 2, and a lifting hole 26 is opened on the triangular plate 25. When the inner frame 2 needs to be installed / disassembled, an external tool is inserted into the lifting hole 26, and then the external tool is pulled to drive the triangular plate 25 and the inner frame 2 to be installed / disassembled.

[0041] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
