Description

Technical Field

[0001] The utility model belongs to the technical field of municipal drainage and relates to an anti-sinking rainwater outlet. Background Art

[0002] The rainwater inlet is an important part of the municipal road drainage facilities, which collects rainwater from the road surface and transports it to the rainwater main. The rainwater inlet is generally set at the edge of the road. When the road is not made of flat curbstones, asphalt will be directly filled around the grating. The asphalt pavement around the rainwater inlet is difficult to compact, and the rainwater inlet grating and the surrounding asphalt will be frequently rolled by vehicles. The commonly used rainwater inlet structure now has a rainwater inlet grate that is directly rigidly connected to the lower water collection compartment. With the frequent rolling of vehicles, the asphalt pavement around the rainwater inlet will be loosened, damaged and settled, further affecting driving comfort and driving safety. Summary of the invention

[0024] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0025] like Figure 1 As shown, the utility model is an anti-sinking rainwater outlet, comprising a rainwater outlet grate 1 and a water collecting chamber 2 arranged up and down, and asphalt is filled between the rainwater outlet grate 1 and the water collecting chamber 2.

[0026] like Figure 2-Figure 3 As shown, the rainwater outlet grate 1 includes a grate frame, a cover plate 5 is placed in the grate frame, the upper part of the grate frame is an upturned flange 3, the inner periphery of the upturned flange 3 is a rainwater hole 3-1, and the inner periphery of the rainwater hole 3-1 is provided with a cover plate positioning groove 3-2.

[0027] The grate frame and the cover plate 5 are made of ductile iron, and are mainly used to withstand wheel rolling and collect rainwater.

[0028] like Figure 4 As shown, the cover plate 5 serves to collect rainwater, and water inlet holes 5-1 are evenly distributed on the cover plate 5. In this embodiment, the cover plate 5 is rectangular in shape, and two rows of water inlet holes 5-1 are evenly distributed in the cover plate 5. The water inlet holes 5-1 are rectangular in shape when viewed from above. The cover plate 5 is placed in the cover plate positioning groove 3-2 and can be opened for easy maintenance.

[0029] In order to beautify the shape of the cover plate 5, the upper surface of the cover plate 5 adopts a water wave shape.

[0030] The water collecting chamber 2 can be made of bricks, cast-in-place concrete or prefabricated, etc., and plays the role of conveying rainwater. A rainwater connecting pipe 6 is connected to the water collecting chamber 2, and rainwater is connected to the rainwater main pipe through the rainwater connecting pipe 6.

[0031] Asphalt is filled between the top of the water collecting chamber 2 and the rainwater outlet grate 1. The middle of the water collecting chamber 2 is a rainwater collecting hole, and the lower part of the grate frame is a positioning ring wall 4, which is adapted to the upper part of the rainwater collecting hole, and the positioning ring wall 4 gradually shrinks from top to bottom, and the lower end of the positioning ring wall 4 extends into the upper part of the rainwater collecting hole but the two do not touch.

[0032] The top surface of the upturned flange 3 is flush with the top surface of the cover plate 5, and the width of the upturned flange 3 is 8~15cm, and 10cm is taken as an example in this embodiment; the spacing of the side walls 4 is equivalent to the net width of the water collection chamber 2, and the height of the side walls 4 is slightly larger than the thickness of the asphalt surface layer, generally 15~25cm, and 20cm is taken as an example in this embodiment.

[0033] The working process of the utility model is as follows:

[0034] When implementing the rainwater inlet, the water collection chamber 2 of the brick or concrete structure is implemented until the top surface is flush with the bottom surface of the asphalt. Before paving the asphalt, a temporary template 7 is set, such as Figure 5 As shown, the temporary template 7 is arranged inside the water receiving chamber 2 and fits closely with the side wall of the water receiving chamber 2, so that the asphalt can be spread to the edge of the water receiving chamber 2 but no asphalt will enter the water receiving chamber 2. When spreading asphalt, the asphalt within a range of about 1 meter around the rainwater outlet should not be completely compacted for the time being, but the height to be sunk after the asphalt is compacted in the later stage should be considered, and the uncompacted asphalt around the rainwater outlet should be 1-3 cm higher than the surrounding road surface. After the asphalt is paved and formed, the temporary formwork 7 is removed, the rainwater outlet grate 1 is covered on the water collection chamber 2, the side wall 4 is inserted into the paved asphalt and the water collection chamber 2, the upturned flange 3 acts on the asphalt pavement, and then the asphalt around the rainwater outlet that has not been completely compacted is compacted together with the rainwater outlet grate 1 by a roller. After the compaction is completed, the asphalt pavement around the rainwater outlet is flush with the surrounding asphalt pavement, and the upturned flange 3 of the rainwater outlet grate 1 is flush with the asphalt pavement. At the same time, during the compaction process, the asphalt is tightly combined with the cover plate 5 of the rainwater outlet grate 1 to form a whole.

[0035] In the rainwater outlet implemented in this way, the rainwater outlet grate 1 is no longer directly connected to the water collecting chamber 2, but is transitioned through the asphalt pavement, avoiding the connection between rigid and rigid structures, and greatly improving driving comfort; in the asphalt rolling process, the asphalt and the rainwater outlet grate 1 are rolled and formed together, and there are no obstacles affecting the compaction of the asphalt, which can better ensure the compaction quality of the asphalt pavement and effectively avoid the diseases of the asphalt pavement in the later period; at the same time, because the rainwater outlet grate 1 acts on the asphalt pavement and basically has no force with the water collecting chamber 2, if the asphalt pavement does not settle, the rainwater outlet grate 1 will not settle either. If the asphalt pavement settles, the rainwater outlet grate 1 will also settle together, and the asphalt pavement and the rainwater outlet grate 1 will always remain in a flush state, thereby completely realizing the anti-subsidence of the rainwater outlet.

[0036] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
