Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway drainage, in particular to a drainage structure based on highway design. Background Art
[0002] Highway drainage structure is essential in highway design. It helps to drain rainwater and prevent water accumulation on the road, thereby improving the safety and durability of the road. Common drainage structures generally use rainwater well drainage system or curbstone drainage system. The rainwater well drainage system is to dig a rainwater well on the road surface, collect rainwater and guide it into the rainwater well. The rainwater well is equipped with a rainwater branch pipe connected to the main drainage pipe; the curbstone drainage system adopts a vertical drainage method, which also collects rainwater into the rainwater well and then collects it into the main road.
[0003] The above-mentioned methods are prone to blockage when there are many fallen leaves in autumn or too much debris on the road, which affects the drainage effect and reduces driving safety. Therefore, it is necessary to invent an efficient and non-blocking road drainage structure. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model develops a drainage structure based on highway design, which does not require rainwater outlets to be set on the road surface, and the spacing between inspection wells can be appropriately increased, thus avoiding the problem of rainwater outlet blockage and improving drainage efficiency and road surface aesthetics.
[0005] The technical solution to the technical problem solved by the utility model is: a drainage structure based on highway design, including a roadbed and a water-stabilizing layer, the water-stabilizing layer is located above the roadbed, and also includes a concrete layer, piers, a permeable layer and a collecting chamber, the concrete layer is located above the water-stabilizing layer, the concrete layer is provided with piers at intervals, the permeable layer is located above the piers, the collecting chamber is located between the concrete layer and the permeable layer, the collecting chamber is connected to an inspection well through a downpipe, the inspection well is connected to a drainage pipe, the inspection well and the drainage pipe are buried in the roadbed, and a manhole cover is hinged at a corresponding position of the inspection well on the permeable layer.
[0006] Preferably, the pier is a truncated cone structure, and the diameter of the circle gradually increases in the direction away from the permeable layer.
[0007] Preferably, a steel mesh is provided at the bottom of the permeable layer.
[0008] Preferably, the steel mesh is provided with a reinforcing hoop at the manhole cover.
[0009] Preferably, a ladder is provided in the inspection well.
[0010] Preferably, a sand and gravel cushion layer is provided at the bottom of the drainage pipe.
[0011] Preferably, the permeable layer is made of permeable asphalt.
[0012] Preferably, the inspection well is a precast concrete inspection well.
[0013] Preferably, the permeable layer, piers and concrete layer are an integral structure that together constitute a pavement layer.
[0014] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:
[0015] 1. The utility model replaces the traditional method of setting up rainwater outlets for road drainage, and uses the permeable layer to directly drain the road surface, which will not cause the phenomenon of water accumulation on the road surface due to blockage of the drainage outlet, thereby improving the drainage efficiency;
[0016] 2. Since the pavement permeable layer has filtered out the large particulate impurities and some debris on the pavement, there will not be too much silt and debris entering the drainage pipe, which can greatly reduce the number of regular cleanings. At the same time, the distance between the two inspection wells can be appropriately increased, saving costs;
[0017] 3. By installing a steel mesh under the permeable layer, the overall strength of the pavement is improved and the service life of the pavement is extended;
[0018] 4. The permeable layer, pier and concrete layer of the utility model are integrated structures, which are prefabricated in the factory. During construction, the road surface construction can be completed by pouring concrete on both sides after on-site hoisting and laying. This method has higher construction efficiency. In the traditional process, the asphalt layer of the road surface must be constructed in winter. The prefabricated structure can also be used for road surface construction in winter, which can greatly shorten the construction period.
[0019] 5. The pier is set as a truncated cone structure with a circular diameter gradually increasing in the direction away from the permeable layer, so that the force transmitted from the permeable layer can be dispersed to the concrete layer, thereby improving the strength of the pavement layer;
[0020] 6. By setting up a collecting chamber, it can play a certain role in storing water when the flow of the drainage pipe reaches the upper limit, and can temporarily transport water along the road direction. When it reaches the section with smaller water flow, it will flow into the drainage pipe through the downpipe, achieving a better drainage effect;
[0021] 7. The utility model does not need to set up rainwater outlets and install rainwater grates on the road surface, and can appropriately increase the distance between two adjacent inspection wells, thereby improving the aesthetics of the road surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0030] Example 1
[0031] See also Figures 1 to 6 A drainage structure based on highway design includes a roadbed 1 and a water-stable layer 2, wherein the water-stable layer 2 is located above the roadbed 1, and further includes a concrete layer 3, a pier 4, a permeable layer 5 and a collecting chamber 9, wherein the concrete layer 3 is located above the water-stable layer 2, and the piers 4 are arranged at intervals on the concrete layer 3, the permeable layer 5 is located above the pier 4, and the collecting chamber 9 is located between the concrete layer 3 and the permeable layer 5, the collecting chamber 9 is connected to a manhole 6 through a downpipe 8, the manhole 6 is connected to a drainage pipe 7, the manhole 6 and the drainage pipe 7 are buried in the roadbed 1, and a manhole cover 61 is hinged at a corresponding position of the manhole 6 on the permeable layer 5.
[0032] like Figure 2 and Figure 4 As shown, the pier 4 is a truncated cone structure, and the diameter of the circle gradually increases in the direction away from the permeable layer 5. The piers 4 are arranged in a linear array in both the length and width directions of the road surface.
[0033] like Figure 6 As shown, a steel mesh 51 is provided at the bottom of the water-permeable layer 5 , and a reinforcing hoop 52 is provided at the manhole cover 61 of the steel mesh 51 . The steel mesh 51 can be cast together with the water-permeable layer 5 during processing.
[0034] like Figure 2 and Figure 4 As shown, a ladder 62 is provided in the inspection well 6 .
[0035] like Figure 1 As shown, a sand and gravel cushion layer 71 is arranged at the bottom of the drainage pipe 7.
[0036] The permeable layer 5 is made of permeable road materials such as permeable asphalt or permeable concrete.
[0037] The inspection well 6 is a prefabricated concrete inspection well 6, which can be placed in place during the roadbed construction, and does not need to be manually laid bricks in the later stage, which can shorten the construction period.
[0038] like Figure 2 and Figure 4 As shown, the permeable layer 5, the pier 4 and the concrete layer 3 are an integral structure and together constitute the pavement layer.
[0039] Principle and operation process
[0040] The utility model is suitable for road surface drainage of highways, and mainly includes a roadbed 1, a water-stabilizing layer 2, a concrete layer 3 and a permeable layer 5. Inspection wells 6, downpipes 8 and drainage pipes 7 need to be pre-buried in advance during roadbed construction. When encountering water accumulation on the road surface during rainy days, the accumulated water will enter the collecting chamber 9 through the permeable layer 5. There is an opening in the collecting chamber 9 connected to the downpipe 8. The water in the collecting chamber 9 flows into the inspection well 6 through the downpipe 8 and is discharged through the drainage pipe 7. A sand and gravel cushion layer 71 is arranged under the drainage pipe 7, which can better protect the drainage pipe 7 and prevent the drainage pipe 7 from cracking due to uneven settlement of the roadbed.
[0041] The piers 4 between the permeable layer 5 and the concrete layer 3 are arranged in an array. By being arranged as a truncated cone structure with a circular diameter gradually increasing in the direction away from the permeable layer 5, the force transmitted from the permeable layer 5 can be dispersed to the concrete layer 3, thereby improving the strength of the pavement layer. At the same time, due to the interval arrangement, it will not affect the water in the collecting chamber 9 from flowing toward the opening and into the downpipe 8.
[0042] A manhole cover 61 is hinged on the permeable layer 5 at the corresponding position of the inspection well 6. The steel mesh 51 below the manhole cover 61 reserves a passage for people to enter the inspection well 6. At the same time, a reinforcing hoop 52 is also provided on the outer circle to prevent the manhole cover 61 from sinking due to weak steel bars at this place due to long-term stress. A ladder 62 is also provided in the inspection well 6 to facilitate personnel to enter and exit during later maintenance.
[0043] The permeable layer 5, the pier 4 and the concrete layer 3 are an integrated structure, which is prefabricated in the factory. During construction, the road surface construction can be completed by pouring concrete on both sides after on-site hoisting and laying. Through this method, the construction efficiency is higher. In the traditional process, the asphalt layer of the road surface must be constructed in winter. The use of prefabricated structures allows the road surface construction to be carried out in winter, which can greatly shorten the construction period.
[0044] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
