Description

Technical Field

[0001] The invention relates to the technical field of highway drainage, and in particular to a super-multi-lane super-wide road surface gap drainage system for highways. Background Art

[0002] Compared with ordinary integrated two-way four-lane or six-lane expressways, super-multi-lane and super-wide expressways (usually integrated two-way ten-lane or more) have larger catchment areas and longer water flow paths. Under the same conditions, their road flow is larger and the drainage time is longer, which leads to more prominent issues such as road driving safety and road drainage design.

[0003] For extra-wide roads, the duration of highway slope confluence will increase to a certain extent, which may easily lead to moisture or even water accumulation on the right hard shoulder and driving lane.

[0004] When the water on the road reaches a certain thickness, the tire-road contact area is significantly reduced due to the wedging of water. The tires traveling at high speed may separate from the road and experience hydroplaning, which may cause the vehicle to lose control and lead to traffic accidents.

[0005] Current research mainly focuses on the drainage design of central median strips, the design of roadbed drainage layers and the drainage design of some special sections, but lacks systematic and comprehensive drainage design for highway sections with waterlogging risks. Summary of the invention

[0006] In order to solve the above-mentioned drainage technical problem of multi-lane and ultra-wide highways, the present invention provides a gap drainage system for ultra-multi-lane and ultra-wide highways. The following technical solutions are adopted:

[0007] A slot drainage system for super-wide road surfaces with multiple lanes on expressways is used for drainage of super-wide road surfaces with multiple lanes on expressways. The drainage system comprises slot drainage ditches and a plurality of transverse drainage devices. The slot drainage ditches are provided on the road surface. The transverse drainage devices comprise slot water collection wells, transverse drainage pipes, rapids troughs and drainage ditches. Slot water collection wells are provided at the bottom of the slot drainage ditches at set intervals. The top of the slot water collection wells is connected to the bottom of the slot drainage ditches. One end of the transverse drainage pipe is connected to the bottom of the slot water collection well. The rapids trough is installed on the side slope of the expressway. One end of the rapids trough is connected to the other end of the transverse drainage pipe. The drainage ditch is provided at the bottom of the side slope of the expressway. The other end of the rapids trough is connected to the drainage ditch.

[0008] Optionally, a double yellow line dividing strip is drawn between the second and third lanes of the road surface, and a gap drainage ditch is opened in the middle of the double yellow line dividing strip.

[0009] The above technical solution is applicable to drainage of super-wide and multi-lane roads on expressways. Super-wide and multi-lane roads on expressways mainly refer to integral two-way expressways with ten lanes or more.

[0010] This is mainly done by setting up a double yellow line dividing strip between the second and third lanes, and setting up a slit drainage ditch in the double yellow line dividing strip to intercept the water on the driving lane, reduce the water flow path, and allow the water in the driving lane to be discharged from the pavement structure more quickly.

[0011] The water trapped in the slit drainage ditch is temporarily stored in the slit drainage ditch, and discharged out of the pavement structure through the collection well and the transverse drainage pipe at the bottom in sequence. The transverse drainage pipe is connected to the rapids trough of the highway slope, and finally discharged through the drainage ditch at the bottom. It can achieve efficient drainage of super-wide roads with multiple lanes on highways and avoid water accumulation that affects driving safety on highways.

[0012] Optionally, the slit drainage ditch includes a water collecting section and a water storage section, the top of the water collecting section is flush with the road surface, the opening of the water storage section is integrally connected with the bottom of the water collecting section, and the cross-sections of the water collecting section and the water storage section form an inverted Ω shape.

[0013] By adopting the above technical solution, the gap-type drainage ditch is actually an Ω ditch, which is usually made of prefabricated concrete and has an inverted Ω-shaped cross-section. It has good structural stability and a certain water storage capacity in the water storage section, and can efficiently complete the water collection and drainage work on the highway pavement.

[0014] Optionally, the lateral drainage devices are spaced 30 meters to 50 meters apart.

[0015] By adopting the above technical solution, the lateral drainage device spacing of 30 meters to 50 meters can meet the drainage needs of highways.

[0016] Optionally, the central axis of the transverse drainage pipe forms an angle α with the surface of the road surface, α>1°.

[0017] By adopting the above technical solution, the transverse drainage pipe needs to be inclined at an angle of α, so that the accumulated water in the slit drainage ditch can be discharged through the transverse drainage pipe as quickly as possible.

[0018] Optionally, the drainage system also includes a plurality of flow disturbance devices, which are respectively located in the middle part of two adjacent lateral drainage devices, the flow disturbance devices include a flexible disturbance part and a water flow disturbance driving part, a flow disturbance port is arranged at the bottom of the slit-type drainage ditch located in the middle area of ​​the two adjacent lateral drainage devices, a power part cavity is arranged at the bottom of the flow disturbance port, the flexible disturbance part covers the flow disturbance port of the slit-type drainage ditch, and the water flow disturbance driving part is installed in the power part cavity, when the water flow disturbance driving part is actuated, the flexible disturbance part is lifted upward and retracted, and the ups and downs of the flexible disturbance part disturb the water stored in the slit-type drainage ditch.

[0019] By adopting the above technical solution, considering that the length of the slit drainage ditch is very long and it is not very flat due to factors such as construction, there is a probability that the water in the middle cannot be discharged in time, thus causing regional water accumulation on the road surface. By setting a flow disturbance device in the middle of two adjacent transverse drainage devices, the water in the water storage section of the slit drainage ditch on both sides of the flow disturbance device can be disturbed to accelerate the discharge of the water.

[0020] The flow disturbance device uses a water flow disturbance driving part to drive the flexible disturbance part to extend and retract upwards, thereby disturbing the water in the gap-type drainage ditch, thereby accelerating the discharge of the water in the water storage section.

[0021] Optionally, the flexible disturbance part includes a metal mounting ring and a flexible part, the metal mounting ring is installed at the spoiler port of the slit-type drainage ditch, the bottom surface of the flexible part can be detachably mounted on the top surface of the metal mounting ring, and the flexible part is made of corrosion-resistant and aging-resistant material, and the corrosion-resistant and aging-resistant material refers to rubber material, thermoplastic elastomer or silicone material.

[0022] By adopting the above technical solution, because the life of the flexible part cannot be very long, usually not exceeding 10 years, its replaceability must be considered. The metal mounting ring is made of corrosion-resistant materials, such as stainless steel, and the bottom surface of the flexible part can be installed with the top surface of the metal mounting ring by bonding or screwing. During the later road maintenance, the flexible part can be replaced together.

[0023] Optionally, the water flow disturbance drive unit includes a micro-telescopic electric cylinder and a cylinder controller. The bottom of the micro-telescopic electric cylinder can be detachably mounted on the bottom of the power unit cavity. When the piston rod of the micro-telescopic electric cylinder is in an initial retracted state, the end of the piston rod abuts against the bottom surface of the flexible part. The cylinder controller controls the execution action of the micro-telescopic electric cylinder. When the cylinder controller controls the piston rod of the micro-telescopic electric cylinder to extend, the piston rod of the micro-telescopic electric cylinder lifts the flexible part. When the piston rod of the micro-telescopic electric cylinder is retracted, the flexible part recovers.

[0024] By adopting the above technical solution, a micro-telescopic electric cylinder is used to drive the ups and downs of the flexible part. The power supply of the specific micro-telescopic electric cylinder can be based on a solar energy device installed on the roadside. Combined with a rain sensor, it can work when the rainfall is heavy, and the discharge of accumulated water can be accelerated during heavy rain.

[0025] Optionally, the water flow disturbance driving unit includes an air source component, a pressure controller, an integrated block and multiple pressure delivery pipes, the high-pressure gas outlet of the air source component is connected to the air inlet of the integrated block through a pipe, the integrated block is provided with multiple exhaust ports, the multiple exhaust ports are respectively connected to the power part cavity of multiple spoiler devices through multiple pressure delivery pipes, the pressure controller controls the air pressure output by the air source component, when the pressure controller controls the air source component to output high-pressure gas, the high-pressure gas inflates the flexible parts of the multiple spoiler devices respectively through the integrated block and the multiple pressure delivery pipes, when the pressure controller controls the air source component to release pressure, the air pressure of the air source component is reduced to normal pressure, and the pressure is released at the pressure controller, and the flexible parts of the multiple spoiler devices are restored.

[0026] Optionally, the air source is an air compressor.

[0027] By adopting the above technical solution, the water flow disturbance driving part can also be a mode in which high-pressure gas is used to inflate the flexible parts. Specifically, the high-pressure gas output by the air compressor can inflate the flexible parts of multiple flow disturbance devices respectively through the integrated block and multiple pressure delivery pipelines. When restoring, it is only necessary to reduce the air pressure to close to the normal air pressure.

[0028] In summary, the present invention includes at least one of the following beneficial technical effects:

[0029] The present invention can provide a gap drainage system for super-wide road surfaces with multiple lanes on expressways, which is suitable for drainage of super-wide road surfaces with multiple lanes on expressways. Super-wide road surfaces with multiple lanes on expressways mainly refer to integral two-way expressways with ten lanes or more.

[0030] This is mainly done by setting up a double yellow line dividing strip between the second and third lanes, and setting up a slit drainage ditch in the double yellow line dividing strip to intercept the water on the driving lane, reduce the water flow path, and allow the water in the driving lane to be discharged from the pavement structure more quickly.

[0031] The water trapped in the slot drain is temporarily stored in the slot drain and discharged out of the pavement structure through the water collection well and the lateral drain pipe at the bottom. The lateral drain pipe is connected to the rapid flow trough on the highway slope and finally discharged through the drain at the bottom.

[0032] By arranging a flow disturbance device in the middle of two adjacent transverse drainage devices, the water stored in the water storage section in the slit drainage ditch on both sides of the flow disturbance device can be disturbed to accelerate the discharge of the stored water.

[0033] It can achieve efficient drainage of super-wide roads with multiple lanes on highways, avoiding water accumulation that affects highway driving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The gap-type drainage ditch 1 is actually an Ω ditch, which is usually made of prefabricated concrete, has an inverted Ω-shaped cross section, and has good structural stability. The water storage section 12 has a certain water storage capacity and can efficiently complete the water collection and drainage work on the highway pavement.

[0051] In Example 4, the interval between the lateral drainage devices is 30 meters to 50 meters.
