Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the sponge city transformation project, in order to ensure that rainwater enters a concave green land through a curb opening to be cleared, a layer of water sealing plate is usually directly covered on a rainwater grate. The method has poor landscape effect, completely seals the current rainwater inlet, and easily causes water accumulation around the sealed rainwater inlet if concave green land is not cleared up timely during medium and large rains. The application provides a inlet for stom water shutoff structure can be used to the shutoff of current situation inlet for stom water in the sponge city transformation project. Install this block structure in rainwater grate below, reduced the harmful landscape influence that the transformation caused, this inlet for stom water still can exert drainage function under the heavy and medium rain operating mode moreover, has avoided the peripheral waterlogging ponding's of conventional inlet for stom water problem of shutoff inlet for stom water when leading to heavy and medium rain because of the shutoff, and big generous easy and simple management and maintenance unit carries out daily maintenance and clearly draws simultaneously.

Specifically, as shown in fig. 1 and 2, the gully device provided by the present application includes a gully 10, a gully grate 20, and a gully plugging structure installed in the gully 10. The gully 10 has a side wall, an upper end and a lower end outlet 12, typically mounted adjacent to the curb, with a notch 11 in the side wall of the gully 10 adjacent to the curb. The kerb is generally provided with a kerb 30, and the kerb 30 is provided with a concave greenbelt at one side thereof, and the opening of the kerb 30 is generally provided at the gully 10. A blocking structure is arranged in the rainwater inlet 10, so that primary rainwater can enter the peripheral greening through the opening 31 of the curb 30 preferentially to be naturally cleared. A trash rack 40 can be arranged at the notch 11 (the opening 31 of the kerb 30) of the gutter inlet 10 to prevent sundries from being washed into a green belt.

As shown in fig. 2 to 4, the gully plugging structure of the present application includes a water baffle 50, an overflow port 51 and a dirt intercepting groove 52 are provided on the water baffle 50, and the dirt intercepting groove 52 is recessed on one side of the water baffle 50. When in use, the rainwater grate 20 covers the upper end opening of the rainwater port 10, and the water baffle 50 is arranged below the rainwater grate 20 and is blocked in the rainwater port 10. The overflow port 51 of the baffle 50 is higher than the bottom of the notch 11 of the gully 10, so that the incipient rain can enter the peripheral green belt from the opening 31 of the curb 30 through the notch 11 of the gully 10 for natural elimination. During heavy and medium rainfall, the excessive rainwater can enter the lower end of the rainwater port 10 through the overflow port 51 of the water baffle 50, and the rainwater enters the urban drainage system from the drainage port 12 at the lower end of the rainwater port 10 to be discharged, so that the problem of water logging at the periphery of the conventional rainwater port due to plugging during heavy and medium rainfall is avoided, and the risk of water logging is reduced. Pollutants brought by the rainwater can be deposited in the sewage interception tank 52 and cleaned regularly, so that impurities such as sludge are prevented from blocking the overflow port. Considering that the initial rain contaminant content is high and the contaminant deposition is liable to occur on the water guard 50, the water guard 50 is designed to have a certain slope, and the intercepting drain 52 is provided at the bottom of the slope. That is, the dirt catching groove 52 is disposed adjacent to the notch 11 of the gutter inlet 10, and the water baffle 50 is disposed obliquely toward the dirt catching groove 52, so that the pollutants are finally collected into the dirt catching groove 52 under the action of gravity and rain wash, and the pollutants are periodically cleaned by the maintenance unit, thereby preventing the pollutants from being deposited and blocking. In order to better block incipient rain and pollutants, the gap between the water baffle 50 and the gully 10 may also be sealed, that is, the water baffle 50 is connected to the sidewall of the gully 10 in a sealing manner, for example, glass cement or other glue may be used for fixing and gap blocking.

In order to facilitate the daily cleaning of the management and maintenance unit, in this embodiment, as shown in fig. 3 and 4, a dredging basket 53 is arranged in the sewage intercepting groove 52, the pollutants are collected in the dredging basket 53, and the dredging basket 53 is lifted to remove the pollutants during cleaning. Because daily clear drawing needs to open and close the rainwater grate relatively frequently, and traditional rainwater grate is heavier, is unfavorable for managing personnel's operation, therefore establish rainwater grate 20 as foldable grate in this embodiment. Specifically, the folding grate comprises a connecting end 21 movably connected with the gutter inlet 10 and an opening end 22 opposite to the connecting end 21, and the opening end 22 is positioned above the sewage interception groove 52. For example, the rainwater grate 20 can be fixed on the rainwater port 10 through the bearing by additionally installing the bearing at one end of the rainwater grate 20, so that the rainwater grate 20 can be prevented from being stolen, and meanwhile, the bearing can rotate and turn over. The middle bearing enables the rainwater grate 20 to be folded and folded, the opening end 22 is located above the sewage intercepting groove 52, the rainwater grate 20 is opened locally and the dredging lifting basket 53 is taken out conveniently for cleaning, and the maintenance personnel only need to fold the grate when taking and placing the dredging lifting basket 53, so that the daily maintenance and cleaning of the maintenance unit are facilitated greatly.

As shown in fig. 3 and 4, to facilitate installation of the water guard plate 50 in the gully 10, the rainwater blocking structure in this embodiment further has a bracket 54 below the water guard plate 50 for supporting the water guard plate 50. For example, a plurality of support uprights may be provided at the periphery of the splash guard 50, and the splash guard 50 is supported in the gutter inlet 10 by the support uprights, so that the splash guard 50 is as high as a concave green space on the curb 30 side, thereby smoothly discharging the initial rain into the green space.

In this embodiment, the water guard 50 is made of stainless steel, and the dredging basket 53 is mainly used for collecting the deposited gravel and other contaminants, so that it is preferably made of a water-impermeable material. Of course, in other embodiments, the water baffle can be made of other rigid materials, and the dredging basket can be made of other water-permeable filtering materials. In order to prevent the breeding of mosquitoes and flies in summer caused by excessive water accumulation in the sewage interception groove 52 and the dredging basket 53, the depths of the sewage interception groove 52 and the dredging basket 53 are not too large, for example, the depth of the sewage interception groove 52 can be in the range of 3 cm-5 cm, so that a small amount of water can be removed by virtue of evaporation in time, and the breeding of mosquitoes and flies is reduced.

The illustration of this application is explained taking square inlet for stom water as an example, and corresponding breakwater shape and inlet for stom water phase-match, cut dirty groove and desilting hand-basket and locate the breakwater and be close to curb one side, cut dirty groove and desilting hand-basket and establish to the rectangle, length and breakwater unanimity, and the width can be less than half of breakwater. In other embodiments the shape of the catch basin and the dredging basket may be designed according to the actual shape of the gully, for example in a circular gully, the catch basin and the dredging basket may be designed as a sector.

In light of the foregoing description of the preferred embodiments of the present invention, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention.
