Description

Technical Field

[0001] The utility model relates to the field of urban roads and drainage, in particular to an urban permeable drainage walkway structure. Background Art

[0002] During the construction of urban road facilities, a large area of ​​space will be occupied to meet the needs of construction facilities. In addition, urban pedestrian walkways and their drainage systems are mostly built independently, resulting in long construction time, long occupation period of surrounding space, and separate construction will also occupy more land resources. In addition, for green areas such as park walkways, building a separate drainage system will also damage the integrity of the landscape and affect the viewing of the park landscape.

[0003] A Chinese patent (publication number CN 116479705 A) discloses a construction method for collecting and reusing water resources on urban roads, which adds a gravel ditch between the sidewalk and the green belt to achieve the functions of water permeability and water storage, and stores the collected water in the gravel ditch water collection well. The gravel ditch is used as a drainage structure, but the sidewalk and the gravel ditch still need to be constructed separately. Although water permeability and drainage are achieved, independent construction during the construction process will still have an adverse effect on the construction period and occupied space; and the drainage ditch needs to be poured with concrete separately, the overall construction is relatively cumbersome and the construction time is long, which is difficult to meet the needs of rapid construction of road drainage facilities in urban space.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] At present, when constructing urban trails, it is necessary to construct sidewalks and gravel ditches separately, which leads to the problems of long construction period and large construction space. Based on this, the present embodiment provides an urban permeable drainage trail structure, using a structural groove 4 as an external construction mold to form a preset trail filling area 3 and a sewage interception filling area 2, constraining the construction scope of the trail structure and the construction scope of the sewage interception structure, and filling with permeable materials to form a permeable trail structure and a sewage interception structure respectively. The sidewalk and the gravel ditch are constructed at one time, which reduces the encroachment on space during construction and improves construction efficiency. The permeable drainage pipe 13 at the bottom of the trail structure is used for drainage to meet the needs of pedestrians and drainage on the trail.

[0030] like Figure 1 As shown, the urban permeable drainage walkway structure is constructed in the soil area 1. A trench for accommodating the structural groove 4 is pre-excavated in the soil area 1, so that the entire urban permeable drainage walkway structure is embedded in the trench to collect and discharge the accumulated water on the top surface of the soil area 1.

[0031] Specifically, Figure 2 As shown, the urban permeable drainage walkway structure mainly includes a structural trough 4, a walkway structure and a sewage interception structure. The structural trough 4 includes a walkway trough 8 and a sewage interception trough 7 connected to both sides of the walkway trough 8. The walkway structure is arranged in the walkway trough 8, the sewage interception structure is arranged in the sewage interception trough 7, and the top surface of the walkway structure forms a sidewalk.

[0032] In view of the problem that the sidewalk and gravel ditch need to be constructed separately, which leads to a long construction period and large space occupation, in this embodiment, a structural groove 4 including a walkway groove 8 and a sewage interception groove 7 is provided, the walkway groove 8 is provided with a walkway filling area 3 with a top opening, and the sewage interception groove 7 is provided with a sewage interception filling area 2 with a top opening, and water-permeable materials are filled in the corresponding walkway groove 8 and sewage interception groove 7 to form a stable structure. Through one construction, the sidewalk and the gravel ditch can be built at the same time, which reduces the occupation of space during construction and improves construction efficiency.

[0033] In order to solve the problem that the current trails have poor water permeability and cannot meet the drainage requirements, in this embodiment, the trail structure is set to include a water permeable layer 10, a water permeable base layer 11 and a gravel base layer 12 distributed from top to bottom, and a water permeable drainage pipe 13 is buried in the gravel base layer 12. The water falling on the water permeable layer 10 can seep downward, pass through the water permeable layer 10, the water permeable base layer 11 and the gravel base layer 12, and enter the water permeable drainage pipe 13, and be discharged by the water permeable drainage pipe 13. Among them, the water permeable layer 10 serves as a sidewalk. Through the design of the multi-layer water permeable structure, the water permeability of the trail is enhanced, and the needs of pedestrians and drainage on the trail are met.

[0034] The permeable drainage pipe 13 has permeable holes on its wall to improve the efficiency of water in the gravel base 12 entering the permeable drainage pipe 13 . The permeable drainage pipe 13 is connected to the distribution area of ​​the gravel base 12 through the permeable holes.

[0035] In this embodiment, the structural groove 4 can be made of stainless steel and is in the shape of a groove as a whole, wherein the walkway groove 8 is 1.5m wide and 88cm deep; the sewage interception groove 7 is 30cm wide and 38cm deep.

[0036] The permeable layer 10 can be laid with permeable cement concrete with a thickness of 18 cm; the permeable base layer 11 is laid with 1-3 cm graded gravel with a thickness of 20 cm, and the bottom of the permeable base layer 11 is flush with the bottom of the interception trough 7; the gravel base layer 12 is a gravel layer with a diameter of 3 cm-5 cm and a thickness of 50 cm. The permeable drainage pipe 13 is laid in the gravel base layer 12, and the slope is synchronized with the distribution slope of the road trough 8. The diameter of the permeable drainage pipe 13 is DN100, which can lead water to the downstream discharge area.

[0037] In order to solve the problem that impurities in rainwater may block the drainage system, the sewage interception structure includes sewage interception gravel 6 arranged in the trail filling area 3 to intercept external impurities. The number of impurities entering the lower part of the sewage interception trough 7 is reduced, the risk of blockage of the drainage hole 9 and the water seepage hole 5 is reduced, and the efficiency is improved. In combination with the above dimensions, the sewage interception gravel 6 in this embodiment can be laid with 1-3cm graded gravel, with a thickness of 38cm.

[0038] When the rainfall is different, the water collection capacity of the urban permeable drainage walkway structure is also different. In order to adapt to the drainage efficiency problem under different water collection capacities. Drain holes 9 are provided on the side wall of the sewage interception trough 7, and seepage holes 5 are provided on the bottom plate. The drainage holes 9 connect the walkway filling area 3 and the sewage interception filling area 2, and the drainage holes 9 connect the walkway filling area 3 and the sewage interception filling area 2, and seepage holes 5 are provided on the bottom plate of the sewage interception trough 7. When the water collection capacity is large, the water body can be quickly guided to the permeable drainage pipe 13 for discharge through the drainage holes 9; when the water collection capacity is small, the water body infiltrates into the soil area 1 through the seepage holes 5 to replenish the groundwater.

[0039] For the arrangement of the drainage holes 9 and the seepage holes 5, as Figure 4 As shown, in the extension direction of the walkway structure, a plurality of drainage holes 9 are spaced apart along the side wall of the sewage interception trough 7; a plurality of seepage holes 5 are provided, and are divided into a plurality of rows in the transverse direction, and the plurality of seepage holes 5 included in each row are spaced apart in sequence along the extension direction of the walkway structure.

[0040] The specifications of the seepage holes 5 and the drainage holes 9 can be set as required. In this embodiment, the seepage holes 5 and the drainage holes 9 have a diameter of 1 cm and are arranged at equal intervals along the longitudinal extension direction of the structural groove 4, with a center-to-center distance of 5 cm between adjacent holes.

[0041] It can be understood that the longitudinal direction in this embodiment refers to the extension direction of the sidewalk, the transverse direction is perpendicular to the extension direction of the sidewalk and is located in the horizontal plane; and the vertical direction is the vertical direction.

[0042] Specifically, in this embodiment, Figure 3 As shown, the bottom plates of the two sewage interception grooves 7 corresponding to the two sides of the walkway groove 8 are coplanarly distributed, and the drainage holes 9 connect the distribution area of ​​the permeable base layer 11 in the walkway filling area 3 and the distribution area of ​​the sewage interception gravel 6 to meet the drainage requirements. When processing the walkway groove 8 and the sewage interception groove 7, the side of the walkway groove 8 connected to the sewage interception groove 7 shares the side plate with the sewage interception groove 7, and the drainage holes 9 are distributed on the side plate shared by the walkway groove 8 and the sewage interception groove 7. The bottom plate of the sewage interception groove 7 is located between the bottom plate of the walkway groove 8 and the top opening of the walkway filling area 3, and the top surface of the gravel base layer 12 is flush with the bottom plate of the sewage interception groove 7.

[0043] like Figure 2 As shown, the top opening of the trail filling area 3 is flush with the top opening of the sewage interception filling area 2, and the top surface of the permeable layer 10 and the top surface of the sewage interception gravel 6 are flush with the top opening of the trail filling area 3, so that the top of the entire structural groove 4 is flush with the sidewalk distribution surface, reducing the structure protruding from the sidewalk to ensure smooth walking.

[0044] In order to facilitate construction, a plurality of structural grooves 4 are provided, which are distributed in sequence along the extension direction of the trail structure. The ends of adjacent structural grooves 4 are butt-jointed, and the corresponding trail filling areas 3 and sewage interception filling areas 2 are connected, thereby ensuring the stability of the connection between the plurality of structural grooves 4 and the continuity of drainage, thereby improving the drainage efficiency.

[0045] When laying out the construction trench 4, some of the seepage holes 5 can be used as fixing holes, and anchors such as anchor rods and positioning rods are pre-driven into the soil area 1. The top of the anchor is exposed outside the soil area 1, and the exposed part of the anchor passes through the seepage holes 5. The sewage interception trench 7 and the anchor are fixedly connected by fasteners, and the sewage interception trench 7 is connected with the anchor to lock the position of the entire construction trench 4.

[0046] It can be understood that the driving depth of anchors such as anchor rods and fixing rods is determined according to the hardness, soil conditions and soil layer distribution of the soil area 1. Of course, since the groove formed by the excavation of the soil area 1 to accommodate the construction groove 4 has a positioning effect on the construction groove 4 itself, the anchor can play an auxiliary positioning role during the construction process.

[0047] In order to ensure that the seepage holes 5 can work normally, some of the seepage holes 5 are selected as fixed holes to establish the connection between the anchor and the sewage interception trough 7, so as to reduce the adverse effect on the seepage capacity of the sewage interception trough 7. Among them, if only the positioning function is performed, a smooth fixed rod can also be used as an anchor, and the seepage holes 5 at the corresponding positions can pass through the anchor inserted into the soil area 1 to achieve coordinated positioning. After the walkway structure and the sewage interception structure in the structural groove 4 are laid out, the anchor is pulled out to restore the seepage capacity of the seepage holes 5 on the sewage interception trough 7 after the positioning function is completed. In order to facilitate the extraction of the anchor after the anchor completes the auxiliary positioning, the top of the anchor can be arranged to extend above the preset top surface of the sewage interception structure. After the sewage interception structure is laid out, the anchor is conveniently pulled out, and then the sewage interception structure is adjusted to the target state.

[0048] It should be pointed out that in the present embodiment, a walkway structure and a sewage interception structure are provided; the permeable layer 10, the permeable base layer 11 and the gravel base layer 12 of the walkway structure are all permeable; the sewage interception gravel 6 is also permeable; the permeable drainage pipe 13 buried in the gravel base layer 12 discharges the water; the water discharge structure is set to be concealed, thereby increasing the aesthetics of the pedestrian walkway area.

[0049] The above detailed description of the specific implementation of the utility model is only used as an example, and the utility model is not limited to the specific implementation described above. For those skilled in the art, any equivalent modification or substitution of the utility model is also within the scope of the utility model. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the utility model should be included in the scope of the utility model.
