Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, and more specifically to a pressure-bearing rainwater grate for stone pavement. Background Art

[0002] The renovation of ancient city streets and lanes in scenic spots, garden projects, and road projects often involve the installation of rainwater and sewage inspection manhole covers. In order to achieve the original retro style effect, stone tiles are usually used for overall paving. Rainwater and sewage inspection manhole covers usually use corresponding stone rainwater grates to solve the problem of rainwater and sewage discharge. Stone rainwater grates generally use large-diameter steel mesh or angle steel brackets as well as wellhead supports. However, there are often heavy vehicles passing through the road surface. Due to the long-term dynamic load of the vehicle, the steel mesh or angle steel bracket is deformed too much, resulting in the bottom of the stone hanging in the air, losing rigid support, and bending deformation, which leads to stone cracks and seriously affects the quality of the project.

[0003] Therefore, it is necessary to improve the prior art. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art, a pressure-bearing rainwater grate for stone pavement with large pressure bearing and good drainage effect is provided.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, a pressure-bearing rainwater grate for stone pavement includes an upper stone grate 1 and a lower pressure-bearing grate 2. The upper stone grate 1 is used to cooperate with a pavement paved with stone tiles, and the lower pressure-bearing grate 2 is arranged at the lower end of the upper stone grate 1 to improve the pressure-bearing capacity of the upper stone grate 1 and prevent the stone from breaking. Preferably, the lower pressure-bearing grate 2 is a prefabricated steel-mixed soil plate, and the opening of the lower pressure-bearing grate 2 is larger than the opening of the upper stone grate 1, so that the drainage speed of the lower pressure-bearing grate 2 is greater than the drainage speed of the upper stone grate 1.

[0025] The upper stone grate 1 is provided with a plurality of water inlets 3, and a through hole 6 is provided in the middle of the lower pressure grate 2. A plurality of pressure-bearing ribs 5 are provided in the through hole 6. The projection of the pressure-bearing ribs 5 in the vertical direction does not overlap with the water inlet 3, so as to prevent the pressure-bearing ribs 5 from affecting the water inlet 3.

[0026] In order to prevent the upper stone grate 1 and the lower pressure grate 2 from being unevenly stressed, resulting in the upper stone grate 1 being partially overstressed and broken, a rubber pad 4 is provided between the upper stone grate 1 and the lower pressure grate 2. The projection of the rubber pad 4 in the vertical direction is within the projection range of the lower pressure grate 2, so that the rubber pad 4 does not affect the drainage of the upper stone grate 1 or the drainage of the lower pressure grate 2.

[0027] A filter screen is detachably connected below the lower pressure grate 2 to filter impurities mixed in rainwater to prevent pipe blockage. The filter screen adopts an existing structure.

[0028] A lifting mechanism 7 is provided between the upper stone grate 1 and the lower pressure grate 2. When the drainage pressure is too large, the upper stone grate 1 is lifted by the lifting mechanism 7 to expand the water inlet and increase the drainage speed.

[0029] Preferably, the lifting mechanism 7 comprises a scissor-type lifting frame, and an upper adjustment groove 8 and a lower adjustment groove 9 are respectively arranged on the end surfaces of the upper stone grate 1 and the lower pressure grate 2 close to each other, for installing the scissor-type lifting frame. The upper and lower ends of one side of the scissor-type lifting frame are respectively hinged to one end of the upper adjustment groove 8 and the lower adjustment groove 9, and the upper and lower ends of the other side of the scissor-type lifting frame are respectively hinged to a slider 13, and are respectively slidably connected to the upper adjustment groove 8 and the lower adjustment groove 9 through the slider 13.

[0030] A mounting hole 10 is provided at one end of the lower adjusting groove 9, and a compression spring 11 is fixedly provided in the mounting hole 10. A push block 12 is fixedly connected to one end of the compression spring 11 away from the mounting hole 10, and one side of the push block 12 is in contact with a slider 13. When the compression spring 11 is in a compressed state, a force can be applied to the push block 12 to move in the direction of the slider 13, so that the upper stone grate 1 is raised under the action of the scissor-type lifting frame.

[0031] In order to lock the position of the upper stone grate 1 under normal circumstances, a positioning hole I14 is provided on the push block 12 in the vertical direction, and a positioning hole II15 is provided on the upper stone grate 1. When the positioning hole II15 is coaxial with the positioning hole I14, the positioning pin 16 is inserted through the positioning hole II15 and the positioning hole I14. At this time, the upper stone grate 1, the rubber pad 4, and the lower pressure grate 2 are fitted in sequence, and the upper end of the upper stone grate 1 is flush with the road surface.

[0032] For convenient operation, the upper end of the positioning pin 16 can be provided with a pull ring 17, and the upper end of the upper stone grate 1 is provided with a slot for placing the pull ring 17. When the upper stone grate 1 needs to be raised, the positioning pin 16 can be pulled out through the pull ring 17.
