Description

Technical Field

[0001] This utility model relates to the field of roadbed and pavement technology, specifically to an easily drainable roadbed and pavement. Background Technology

[0002] Roads refer to highways, urban roads, and places within the jurisdiction of an organization that allow public motor vehicle traffic, including squares, public parking lots, and other places used for public passage. Roads are the heart of a city and the most basic infrastructure project in urban construction. The construction of roads facilitates vehicle travel and also enhances the image of the city.

[0003] In the field of road engineering, the drainage performance of the roadbed and pavement directly affects the service life of the road and driving safety.

[0004] Most existing roadbeds and pavements lack rapid drainage capabilities, relying primarily on drainage manholes installed on the road surface for drainage. This results in some rainwater remaining on the road surface and gradually seeping into the gaps in the asphalt pavement, causing softening of the base layer and a decrease in load-bearing capacity. Over the long term, this can easily lead to pavement settlement, cracking, and potholes. In rainy areas or during periods of concentrated seasonal rainfall, surface water can also infiltrate the roadbed through pavement cracks, causing a sharp increase in the moisture content of the roadbed soil and even triggering structural defects such as roadbed slippage. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide an easily drainable roadbed pavement that solves the problem of relying on drainage manhole covers for drainage, which leads to some rainwater remaining on the road surface, causing a sharp increase in the moisture content of the roadbed soil, and even structural defects such as roadbed slippage. Rainwater is collected and flows into the inner groove of the base through the base holes and grooves, and then guided into the interior of the diversion layer. After that, the rainwater enters the water collection pipe through the water collection holes, and finally flows into the drainage pipe for centralized discharge, so as to make the roadbed pavement dry quickly after rain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an easily drainable roadbed pavement, comprising a pavement component, a base component, a flow guiding component, and a drainage component. The pavement component comprises an asphalt pavement, the base component comprises a waterproof base, the flow guiding component comprises a flow guiding layer, and the drainage component comprises a stabilizing upright plate and a water collection plate. The bottom of the asphalt pavement is fixedly connected to a pavement base layer by compaction and fitting. The waterproof base has an integrally formed inner groove on its inner side, and the top of the waterproof base has a milled groove. The base has a slotted hole, and the two ends of the slotted hole are connected to the base groove through a through structure. The top of the flow guiding layer is fixedly connected to a frame plate by bolts. The top of the frame plate away from the flow guiding layer is fixedly connected to a water conveying plate by a slot. The inner side of the water conveying plate is drilled with equally spaced water conveying holes. The top of the stabilizing upright plate is fixedly connected to a folded plate by welding. The inner side of the water collecting plate is laser-cut with equally spaced water collecting holes. The bottom of the water collecting plate is fixedly connected to a water collecting pipe that corresponds to and is connected to the water collecting holes by hot-melt welding.

[0007] The beneficial effects of this utility model are as follows: rainwater is collected and flows into the inner groove of the base through the base holes and grooves, and then guided into the interior of the guide layer through the inner groove of the base. After that, the rainwater enters the water collection pipe through the water collection holes, and finally flows into the drainage pipe for centralized discharge, which is used to make the roadbed and pavement dry quickly after rain. After the water in each water collection pipe is collected into the drainage pipe, the drainage pipe will directionally transport the water to the external drainage system. The waterproof sleeve can prevent water from the outside of the guide layer from seeping back.

[0008] To allow rainwater that cannot be drained in time to seep into the waterproof base through the pores of the pavement base at the bottom of the asphalt pavement, the rainwater flows along the slope of the base groove to the base slots: As a further improvement to the above technical solution: the waterproof base is fixedly connected to the bottom of the road base layer by a waterproof adhesive layer, and the depth of the base groove is half the depth of the base hole groove.

[0009] The beneficial effects of this improvement are as follows: when drainage is carried out, the rainwater remaining on the road surface is first discharged to the curb through the slope of the asphalt road surface. The rainwater that is not discharged in time seeps into the top of the waterproof base through the pores of the road base at the bottom of the asphalt road. At this time, the rainwater flows to the base groove along the slope of the base groove.

[0010] To ensure that rainwater enters the collection pipe through the collection holes and eventually flows into the drain pipe for centralized discharge: As a further improvement to the above technical solution: the bottom of the base hole groove is connected to the inner groove of the base through a through-hole, and the bottom of the inner groove of the base is connected to the top of the guide layer.

[0011] The beneficial effects of this improvement are as follows: rainwater is collected and flows into the inner groove of the base through the base holes and grooves, and then guided into the interior of the guide layer through the inner groove of the base. After that, the rainwater enters the water collection pipe through the water collection holes and finally flows into the drainage pipe for centralized discharge, which is used to make the roadbed and pavement dry quickly after rain.

[0012] To accelerate the downward flow of water through the conveying orifice under the influence of gravity, the conical orifice structure reduces the risk of water flow blockage. As a further improvement to the above technical solution: water delivery holes are provided at equal intervals on the inner side of the water delivery plate. The water delivery holes are tapered holes that are wider at the top and narrower at the bottom, and are opened through the water delivery plate along its height direction.

[0013] The beneficial effects of this improvement are: after the water in the inner groove of the base flows into the groove at the top of the water conveying plate, it flows downward through the water conveying hole under the action of gravity, and the conical hole structure can reduce the risk of water flow blockage.

[0014] To facilitate rapid flow within the troposphere under the guidance of the deflectors and the effect of the slope: As a further improvement to the above technical solution: the inner wall of the frame plate is fixedly connected with a guide plate by welding, and the space between adjacent guide plates forms a guide channel, which is set with a slope of 2% along the water flow direction.

[0015] The beneficial effects of this improvement are: the frame plate provides stable support for the guide plate, and after the water flows into the guide channel through the water inlet, it quickly flows into the interior of the guide layer under the guidance of the guide plate and the slope.

[0016] To ensure that the water flowing into the guide layer converges along the inclined surface of the folded plate towards the water collection plate, and to prevent the water from stagnating at the bottom of the guide layer: As a further improvement to the above technical solution: the stabilizing plate is vertically fixed to the bottom of the inner wall of the flow guide layer by pre-embedded bolts. There are two folded plates arranged symmetrically. One end of the folded plate is welded and fixed to the top of the stabilizing plate, and the other end is fixedly connected to the inner wall of the flow guide layer by expansion bolts.

[0017] The beneficial effects of this improvement are: by providing vertical support for the folded plate and the water collection plate through the stabilizing upright plate, the water flowing into the guide layer gathers along the inclined surface of the folded plate to the water collection plate, thus preventing the water from stagnating at the bottom of the guide layer.

[0018] In order for some water to flow along the slope of the folded plate to the water collection plate, and for some water to fall directly onto the surface of the water collection plate: As a further improvement to the above technical solution: the two ends of the water collection plate are fixedly connected to the folded plate bolts through flanges, and the two side edges of the water collection plate are sealed to the inner wall of the guide layer through sealing strips.

[0019] The beneficial effects of this improvement are as follows: water flows into the interior of the guide layer from the guide channel by falling, some water flows along the slope surface of the folded plate to the water collection plate, and some water falls directly onto the surface of the water collection plate. Then, the water on the water collection plate flows into the corresponding water collection pipe through the water collection holes.

[0020] To direct water to an external drainage system via the drainage pipes, waterproof sleeves prevent water from seeping back into the drainage layer. As a further improvement to the above technical solution: the end of the water collection pipe away from the water collection plate is sealed to the drain pipe through a reducing joint, and the front end of the drain pipe penetrates the wall of the flow guiding layer through a waterproof sleeve.

[0021] The beneficial effects of this improvement are: after the water in each collection pipe is collected and discharged into the drain pipe, the drain pipe will directionally transport the water to the external drainage system, and the waterproof sleeve can prevent water outside the diversion layer from seeping back in.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] like Figure 1-5As shown, an easily drainable roadbed pavement includes a pavement component 1, a base component 2, a flow guiding component 3, and a drainage component 4. The pavement component 1 includes an asphalt pavement 11, the base component 2 includes a waterproof base 21, the flow guiding component 3 includes a flow guiding layer 31, and the drainage component 4 includes a stabilizing plate 41 and a water collection plate 43. The bottom of the asphalt pavement 11 is fixedly connected to a pavement base layer 12 by compaction. The waterproof base 21 has an integrally formed inner groove 22 in the middle of its inner side, and the top of the waterproof base 21 has a base groove 23 and a base hole 24 formed by milling. Both ends of the seat groove 24 are connected to the base groove 23 through a through structure. The top of the flow guiding layer 31 is fixedly connected to the frame plate 32 by bolts. The top of the frame plate 32 away from the flow guiding layer 31 is fixedly connected to the water conveying plate 33 by a slot. The inner side of the water conveying plate 33 is provided with water conveying holes 34 at equal intervals by drilling. The top of the stabilizing plate 41 is fixedly connected to the folded plate 42 by welding. The inner side of the water collecting plate 43 is provided with water collecting holes 44 at equal intervals by laser cutting. The bottom of the water collecting plate 43 is fixedly connected to the water collecting pipe 45 corresponding to and connected to the water collecting holes 44 by hot melt welding.

[0030] The waterproof base 21 is fixedly connected to the bottom of the road base layer 12 by a waterproof adhesive layer. The depth of the base groove 23 is half the depth of the base hole 24. When drainage is carried out, the rainwater remaining on the road surface first flows to the curb through the slope of the asphalt road surface 11. The rainwater that is not discharged in time seeps into the top of the waterproof base 21 through the pores of the road base layer 12 at the bottom of the asphalt road surface 11. At this time, the rainwater flows to the base hole 24 along the slope of the base groove 23.

[0031] The bottom of the base slot 24 is connected to the base inner slot 22 through a through-hole, and the bottom of the base inner slot 22 is connected to the top of the guide layer 31. Rainwater is collected and flows into the base inner slot 22 through the base slot 24, and then is guided into the interior of the guide layer 31 through the base inner slot 22. After that, the rainwater enters the water collection pipe 45 through the water collection hole 44, and finally flows into the drainage pipe 46 for centralized discharge, so as to make the roadbed and pavement dry quickly after rain.

[0032] Water delivery holes 34 are evenly spaced on the inner side of the water delivery plate 33. The water delivery holes 34 are tapered holes that are wider at the top and narrower at the bottom, and are opened through the height direction of the water delivery plate 33. After the water in the inner groove 22 of the base flows into the groove at the top of the water delivery plate 33, it flows downward faster through the water delivery holes 34 under the action of gravity. The tapered hole structure can reduce the risk of water flow blockage.

[0033] The inner wall of the frame plate 32 is fixedly connected to the guide plate 35 by welding. The space between adjacent guide plates 35 forms a guide channel 36. The guide channel 36 is set with a 2% slope along the water flow direction. The frame plate 32 provides stable support for the guide plate 35. After the water flows into the guide channel 36 through the water inlet 34, it quickly flows into the interior of the guide layer 31 under the guidance of the guide plate 35 and the slope.

[0034] The stabilizing plate 41 is vertically fixed to the bottom of the inner wall of the flow guiding layer 31 by pre-embedded bolts. There are two symmetrically arranged folded plates 42. One end of the folded plate 42 is welded and fixed to the top of the stabilizing plate 41, and the other end is fixedly connected to the inner wall of the flow guiding layer 31 by expansion bolts. The stabilizing plate 41 provides vertical support for the folded plate 42 and the water collecting plate 43. The water flowing into the flow guiding layer 31 is collected along the inclined surface of the folded plate 42 to the water collecting plate 43, so as to avoid the water from stagnating at the bottom of the flow guiding layer 31.

[0035] The two ends of the water collection plate 43 are fixedly connected to the folded plate 42 by flanges and bolts. The two side edges of the water collection plate 43 are sealed to the inner wall of the guide layer 31 by sealing strips. Water flows into the interior of the guide layer 31 from the guide channel 36 by falling. Some water flows along the slope surface of the folded plate 42 to the water collection plate 43, and some water falls directly onto the surface of the water collection plate 43. Then the water on the water collection plate 43 flows quickly into the corresponding water collection pipe 45 through the water collection hole 44.

[0036] The end of the water collection pipe 45 away from the water collection plate 43 is sealed to the drain pipe 46 through a reducing joint. The front end of the drain pipe 46 penetrates the wall of the guide layer 31 through a waterproof sleeve. After the water in each water collection pipe 45 is collected into the drain pipe 46, the drain pipe 46 directs the water to the external drainage system. The waterproof sleeve can prevent water outside the guide layer 31 from seeping back in.

[0037] The working principle of this utility model is as follows: During drainage, the rainwater remaining on the road surface first flows towards the curb through the slope of the asphalt pavement 11. The rainwater that is not drained in time seeps into the top of the waterproof base 21 through the pores of the road base 12 at the bottom of the asphalt pavement 11. At this time, the rainwater flows along the slope of the base groove 23 to the base hole groove 24. The rainwater is collected and flows into the base inner groove 22 through the base hole groove 24, and then guided into the interior of the guide layer 31 through the base inner groove 22. After the water in the base inner groove 22 flows into the groove at the top of the water conveying plate 33, it accelerates downward under the action of gravity through the water conveying hole 34. The conical hole structure can reduce the risk of water flow blockage. The frame plate 32 forms a stable support for the guide plate 35. After the water flows into the guide channel 36 through the water conveying hole 34, it flows into the guide plate 35. Under the guidance and slope, the water flows quickly into the interior of the guide layer 31. The stabilizing plate 41 provides vertical support for the folded plate 42 and the water collection plate 43. The water flowing into the guide layer 31 converges towards the water collection plate 43 along the inclined surface of the folded plate 42, preventing the water from stagnating at the bottom of the guide layer 31. The water flows into the interior of the guide layer 31 from the guide channel 36 in a downward manner. Some of the water converges towards the water collection plate 43 along the inclined surface of the folded plate 42, while some of the water falls directly onto the surface of the water collection plate 43. Subsequently, the water on the water collection plate 43 flows quickly into the corresponding water collection pipe 45 through the water collection hole 44. The water in each water collection pipe 45 is collected and then flows into the drain pipe 46. The drain pipe 46 then directs the water to the external drainage system. The waterproof sleeve can prevent water from seeping back into the exterior of the guide layer 31.
