Description

Technical Field

[0001] The utility model relates to the technical field of road pavement structures, and in particular to a road curb structure with integrated road surface water discharge. Background Art

[0002] Flat curbs or perforated curbs are generally set between existing roads and sunken green spaces. The runoff rainwater generated on the road surface passes through the curbs and directly enters the sunken green space on the roadside. When the water flow is large, the water flow will scour the slope of the sunken green space, affect the growth of slope plants, and cause slope collapse. The common practice of using perforated curbs is that when a single-point rainstorm exceeds the design recurrence period, the rainwater on the road surface cannot be discharged into the sunken green space on both sides of the road in time, which easily causes road waterlogging. Utility Model Content

[0003] The main purpose of the utility model is to provide an integrated road curb structure for road surface water discharge, which is used to solve the problem that the sunken green space is easily washed away and the road surface is easily flooded when the water flow rate is large.

[0006] The overflow structure comprises an overflow well arranged in the sunken green space and a sewage intercepting member arranged on the overflow well; a drainage pipe connected to a road rainwater pipe network is arranged in the overflow well.

[0007] As a further improvement of the utility model, a slope is provided on the side of the sunken green space adjacent to the brickwork; the end of the drain pipe away from the filter element passes through the slope and is located at the upper end of the sunken green space.

[0008] As a further improvement of the utility model, the brick masonry is arranged in two groups side by side, and a storage cavity is provided between the two groups of brick masonry; the filter element includes graded gravel; the graded gravel is located in the storage cavity; the interception element includes a grid plate; the two ends of the grid plate are respectively located on the two groups of brick masonry.

[0009] As a further improvement of the utility model, the overflow well is hollow inside to form an overflow cavity, and the height of the plane where the top of the overflow well is located exceeds the height of the plane where the top of the sunken green space is located.

[0010] As a further improvement of the utility model, the pollution intercepting member comprises a concave pollution intercepting frame; an overflow hole is provided at the bottom end of the pollution intercepting frame.

[0011] The beneficial effects of the utility model are embodied in:

[0012] By setting up filtering elements and intercepting elements, the runoff rainwater from the road can be discharged into the sunken green space after energy dissipation and purification, avoiding the erosion of the green space slope caused by rainwater directly flowing into the sunken green space; the overflow wells, sewage intercepting elements and drainage pipes set up take into account the drainage safety requirements during heavy rains exceeding the design recurrence period, and can ensure that when a single-point heavy rain occurs, rainwater on the road surface can be smoothly discharged into the green belts on both sides of the road, reducing the probability of road waterlogging.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] In one embodiment, see Figure 1 The utility model discloses an integrated road curb structure for road surface water discharge, comprising a road pavement 1, a sunken green space 2, a road rainwater pipe network, a curb structure, and an overflow structure.

[0020] Among them, the curb structure includes a brickwork 3 respectively arranged adjacent to the road surface 1 and the sunken green space 2, a filter 4 arranged between the brickwork platforms, and a retention member 5 arranged on the brickwork 3; the brickwork 3 is arranged along the extension direction of the road surface 1, and a drain pipe 6 is arranged in the filter 4, and the end of the drain pipe 6 away from the filter 4 is located on the surface of the sunken green space 2; the overflow structure includes an overflow well 7 arranged in the sunken green space 2, and a sewage interception member 8 arranged on the overflow well 7, and a drainage pipe 9 connected to the road rainwater pipe network is arranged in the overflow well 7.

[0021] For further information, see Figure 1 A slope 10 is provided on one side of the sunken green space 2 adjacent to the brickwork 3 ; an end of the drain pipe 6 away from the filter element 4 passes through the slope 10 and is located at the upper end of the sunken green space 2 .

[0022] Preferably, the slope ratio of the slope 10 is 1:3.

[0023] For further information, see Figure 1 , 2 Two groups of brick masonry 3 are arranged side by side, and a storage cavity 11 is provided between the two groups of brick masonry 3; the filter element 4 includes graded gravel 12, and the graded gravel 12 is located in the storage cavity 11; the interception element 5 includes a grid plate 13, and the two ends of the grid plate 13 are respectively located on the two groups of brick masonry 3.

[0024] Preferably, the mesh plate 13 is made of plastic, and the upper end surface of the mesh plate 13 is flush with the road surface 1 .

[0025] Preferably, both ends of the road surface 1 are provided with road cross slopes 14 facing the grid plate 13 .

[0026] Preferably, the drain pipe 6 is a DN75UPVC pipe.

[0027] Preferably, see Figure 3 , the aperture of the grid plate 13 is 1.5 cm.

[0028] Preferably, the thickness of the graded crushed stone 12 is 300 mm.

[0029] In the above arrangement, when runoff is generated on the road surface 1 during rainfall, the rainwater runoff flows toward the sunken green space 2 through the road cross slope 14, and then enters the grid plate 13. When the road surface runoff rainwater flows to the grid plate 13, large particles of impurities such as leaves, garbage, and stones carried in the runoff are first intercepted by the grid plate 13, and the large particles of impurities intercepted on the surface can be easily and regularly cleaned up by maintenance personnel; the runoff rainwater without large particles of impurities enters the 300mm thick distributed gravel layer, and during the flow of rainwater, it is blocked by the distributed gravel, generating bypass resistance, consuming most of the kinetic energy of the water flow, and at the same time, small particles of impurities in the water are affected by interception, sedimentation, inertia, diffusion and hydrodynamics, and are intercepted in the distributed gravel layer, so that the runoff rainwater is further purified, and the rainwater purified by the distributed gravel layer is discharged into the sunken green space 2 through the DN75 drain pipe 6, and the sponge function is realized by the storage, infiltration and discharge of the sunken green space 2.

[0030] For further information, see Figure 1 The overflow well 7 is hollow inside to form an overflow cavity 15 , and the height of the plane where the top of the overflow well 7 is located exceeds the height of the plane where the top of the sunken green space 2 is located.

[0031] Preferably, the overflow well 7 is a rectangular body built with bricks, and the height of the overflow well 7 exceeding the sunken green space 2 is in the range of 10 cm to 30 cm.

[0032] For further information, see Figure 1 The dirt intercepting member 8 comprises a concave dirt intercepting frame, and an overflow hole 16 is provided at the bottom end of the dirt intercepting frame.

[0033] Preferably, the vertical cross-section of the pollution intercepting frame is a trapezoidal structure.

[0034] In the above arrangement, when a rainstorm exceeding the designed recurrence period occurs, the runoff rainwater generated by the road surface can also overflow through the curb structure into the sunken green space 2, and then enter the overflow chamber 15 through the overflow well 7 in the sunken green space 2 through the sewage interception frame for discharge. The sewage interception frame intercepts large particles of impurities such as leaves, garbage, and stones mixed in the rainwater, and the rainwater enters the road rainwater network through the drainage pipe 9, thereby ensuring the safety of road drainage.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
