[0002] The urban drainage system is a comprehensive infrastructure network designed to effectively collect, treat and discharge sewage and rainwater generated in the city to ensure the cleanliness of the urban environment and the health of citizens. Currently, the urban drainage system generally includes rainwater wells and drainage grilles on the rainwater, using the slope of the road to collect rainwater into the rainwater wells.
[0003] In urbanization construction, the proportion of hard surface and surface runoff continues to increase. For public buildings, square roads and other types of projects, the proportion of hard pavement is relatively high, resulting in insufficient storage capacity of the sewage and drainage system, and unable to achieve peak drainage and reduce the pressure of urban rainwater discharge. During heavy rainfall, the urban drainage pressure is too high. Therefore, it is necessary to design a shallow storage and light sewage drainage system to solve the above problems.

[0005] In view of the above-mentioned problems existing in the existing shallow storage and light sewage drainage system, the present utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a shallow storage and light sewage drainage system, which is suitable for solving the problem of insufficient storage capacity of the clean sewage drainage system, inability to achieve staggered drainage, reduce urban rainwater discharge pressure, and excessive urban drainage pressure during heavy rainfall.
[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a shallow storage and light sewage drainage system, comprising:
[0008] The main unit includes a foundation and a road pavement layer laid on the foundation, a curbstone is laid on one side of the road, and a storage pavement layer is laid on the side of the curbstone away from the road pavement layer;

A connecting pipe is provided on the lower side of the drainage cavity, and the drainage cavity and the connecting pipe are connected through multiple groups of evenly distributed overflow pipes, and the connecting pipe is connected to the rainwater well.
[0010] As a preferred solution of the shallow storage and light sewage drainage system described in the utility model, the drainage system also includes a permeable paving unit, which includes a gravel cushion layer laid on the upper side of the foundation, a permeable geotextile laid on the upper side of the gravel cushion layer, and a leveling layer laid on the upper side of the permeable geotextile, and the lower ends of multiple overflow pipes sequentially penetrate downward through the leveling layer, the permeable geotextile and the gravel cushion layer.
[0011] As a preferred solution of the shallow storage and light sewage drainage system of the utility model, each of the support columns is configured in a frustum shape, and a plurality of groups of evenly distributed support ribs are fixedly provided at the lower end of the side wall of the support column.

[0015] The beneficial effects of the present invention are as follows: when heavy rainfall occurs, rainwater accumulated on the surface of the road pavement enters the drainage cavity through the drainage outlet arranged on the curbstone. As the amount of water in the drainage cavity continues to increase, the liquid level in the drainage cavity rises, and impurities in the rainwater are precipitated on the lower inner wall of the drainage cavity. Sewage containing less impurities overflows the overflow pipe and enters the connecting pipe, and then enters the rainwater well through the connecting pipe, and is then discharged to the outside. When heavy rainfall occurs, it is possible to regulate and drain rainwater, and discharge it in off-peak conditions, thereby alleviating the pressure of rainwater discharge in the urban drainage system during the same period.

[0024] Example
[0025] Reference Figure 1-Figure 2 , which is an embodiment of the present invention, provides a shallow storage and light sewage drainage system, including: a main unit 100, a storage and drainage unit 200 and a permeable pavement unit 300.
[0026] The main unit 100 includes a foundation 101 and a road pavement layer 102 laid on the foundation 101. A curbstone 103 is laid on one side of the road. A storage pavement layer 104 is laid on the side of the curbstone 103 away from the road pavement layer 102.
[0027] Secondly, the storage and drainage unit 200 includes a rainwater well 201 arranged in the foundation 101, and the rainwater well 201 is arranged to penetrate the road pavement layer 102 upward, and a drainage cavity is opened between the foundation 101 and the road pavement layer 102, and the horizontal height of the lower inner wall of the drainage cavity is lower than the horizontal height of the upper side wall of the road pavement layer 102. This arrangement ensures the storage and drainage capacity of the drainage cavity, and facilitates the discharge of light sewage accumulated on the road into the rainwater well 201. A drainage outlet 202 connected to the drainage cavity is opened on the curb 103, and each drainage outlet 202 is arranged in a long strip shape, and the length of the drainage outlet 202 is one-half to two-thirds of the height of the curb 103. This arrangement ensures the drainage capacity of the drainage cavity. 2 drainage volume per unit time, multiple groups of evenly distributed support columns 203 are fixedly arranged between the lower side wall of the drainage cavity and the regulating and storing pavement layer 104, each support column 203 is arranged in a frustum shape, and multiple groups of evenly distributed support ribs 204 are fixedly arranged at the lower end of the side wall of the support column 203. The setting of the support ribs 204 improves the stable support effect of the support column 203 on the regulating and storing pavement layer 104. A connecting pipe 205 is provided on the lower side of the drainage cavity, and the drainage cavity and the connecting pipe 205 are connected through multiple groups of evenly distributed overflow pipes 206, and the connecting pipe 205 is connected to the rainwater well 201, and the connecting pipe 205 is connected to the upper part of the inner cavity of the rainwater well 201, and the connecting pipe 205 is laid inside the gravel cushion layer 301.
[0028] Secondly, the permeable pavement unit 300 includes a gravel cushion layer 301 laid on the upper side of the foundation 101, and a permeable geotextile 302 is laid on the upper side of the gravel cushion layer 301. The permeable geotextile 302 is made of filament geotextile with a weight of not less than 300g per square meter. A leveling layer 303 is laid on the upper side of the permeable geotextile 302, and the lower ends of multiple overflow pipes 206 sequentially penetrate the leveling layer 303, the permeable geotextile 302 and the gravel cushion layer 301 downward.
[0029] During use, when heavy rainfall occurs, rainwater accumulated on the surface of the road pavement layer 102 enters the drainage cavity through the drainage outlet 202 set on the curb 103. As the amount of water in the drainage cavity continues to increase, the liquid level in the drainage cavity rises, and impurities in the rainwater settle on the lower inner wall of the drainage cavity. Sewage containing less impurities overflows the overflow pipe 206 and enters the connecting pipe 205, and then enters the rainwater well 201 through the connecting pipe 205, and is then discharged to the outside. When heavy rainfall occurs, the rainwater can be regulated and drained, and the peak drainage can be staggered, which alleviates the rainwater discharge pressure of the urban drainage system during the same period.
[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
