Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to the structure and construction method of a test track for factory engineering. Background Technology

[0002] Engineering test tracks are dedicated testing grounds that provide factory performance testing, reliability verification, and fault diagnosis for various vehicles, engineering machinery, or power equipment. Different road conditions are designed according to the type of test object, which can simulate various operating scenarios of equipment in actual use. Through professional instruments, core parameters such as speed, braking performance, power output, and shock absorption effect are collected to ultimately verify whether the equipment meets design standards and safety specifications. It is a key infrastructure for equipment research and development finalization, factory acceptance, and performance improvement.

[0003] The plant's test track structure is a multi-level, multi-condition integrated specialized testing facility, consisting of a foundation load-bearing layer, a functional pavement layer, and supporting auxiliary systems. The foundation load-bearing layer uses compacted lime-soil or concrete subbase to ensure the overall load-bearing capacity of the track, suitable for heavy construction machinery. The functional pavement layer is divided into different functional sections according to testing needs, including flat test sections, bumpy obstacle sections, slope test sections, and wading test pools, capable of simulating complex road conditions in actual equipment operation. The supporting auxiliary systems include parameter monitoring sensors, safety barriers, drainage facilities, lighting, and emergency rescue channels, enabling real-time data collection of equipment operation and ensuring a safe and controllable testing process. The overall structural design must meet the full-process requirements of factory testing, performance verification, and troubleshooting for construction machinery within the plant area.

[0004] During use, traditional factory roads have insufficient load-bearing capacity and durability, which cannot meet the requirements of heavy-load high-frequency testing. Special construction methods are required to improve the structural strength, drainage performance and flatness of the runway, so as to ensure test safety and data accuracy. Summary of the Invention

A baffle is fixedly connected to the bottom of the water collection frame. A pressure pump is fixedly connected to the outer side of the water collection frame. An inlet pipe is connected to the input end of the pressure pump. The end of the inlet pipe away from the pressure pump is fixedly connected to the front side of the water storage tank. An outlet pipe is connected to the output end of the pressure pump. The other end of the outlet pipe is connected to a second hollow tube. Multiple nozzles are connected to the outer side of the second hollow tube.

[0010] Preferably, the multi-layer paving mechanism includes a first grade crushed stone layer laid on top of the base layer, a second grade crushed stone layer laid on top of the first grade crushed stone layer, a coarse sand layer laid on top of the second grade crushed stone layer, a gravel mixture layer laid on top of the coarse sand layer, a geogrid provided in the middle of the gravel mixture layer, a cement-stabilized crushed stone layer laid on top of the gravel mixture layer, and a high wear-resistant asphalt concrete layer laid on top of the cement-stabilized crushed stone layer.

[0014] Preferably, the geogrid is laid horizontally, and the geogrid is flush with the horizontal plate.

[0015] The second aspect of this invention provides a construction method for a test track structure in a factory area, comprising the following steps:

[0016] S1. First, clean the site, mark lines and dig pits. Mix the crushed stone and concrete to solidify into a base layer. Lay the first grade crushed stone layer on the surface of the base layer and compact it.

[0017] S2. When pouring the base layer, multiple horizontal plates are vertically embedded into the bottom of the foundation pit. The fixing steel bars at the bottom of the horizontal plates are poured together with the base layer.

[0023] 2. The water collection frame collects water flow, and the internal sponge absorbs and filters it. The increased weight causes the water collection frame to descend, and some water flows into the water storage tank through the hose. When the weather is dry, the sponge evaporates, the spring rebounds, and the baffle no longer blocks the water inlet. The pressure pump draws water from the water storage tank, pressurizes it, and sprays it out through the nozzle through the pipe for road maintenance. A straight channel is provided on the outside of the water collection frame to guide the overflow.

[0024] 3. The first grade crushed stone layer, the second grade crushed stone layer, and the crushed stone layer are laid and compacted in sequence on the base layer. Then, a sand and gravel mixture layer is laid, and a geogrid is fixed in the middle to enhance stability and convert the load into a uniform lateral force. Next, a cement-stabilized crushed stone layer is laid and compacted, and the top layer is a compacted high wear-resistant asphalt concrete layer to form a flat, wear-resistant, and anti-slip test surface.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8The present invention will be further described in detail below.

[0035] This invention provides a test track structure for factory engineering. Through the combination of a first-grade crushed stone layer 41, a second-grade crushed stone layer 42, a sand and gravel mixed layer 45, and a geogrid 46, the track can withstand high-frequency test runs of heavy-duty engineering vehicles, avoiding settlement and cracking, and improving structural stability. Furthermore, the combination of a coarse sand layer 210 and a curved rod 26 transforms the vertical load into a large-scale, uniformly distributed lateral force. Finally, through the action of the water collection mechanism 3, rainwater can be collected, and the road surface can be sprayed with water for maintenance when it is dry.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, the test track structure of this plant area includes a base layer 1 and a drainage ditch 7. A pressure-reducing mechanism 2 is installed on top of the base layer 1 to diffuse ground pressure. A water-collecting mechanism 3 is also installed on top of the base layer 1 to collect and utilize rainwater. A multi-layer paving mechanism 4 is installed on top of the drainage ditch 7 to reinforce the road surface, enabling the track to withstand high-frequency testing by heavy-duty engineering vehicles. The pressure-reducing mechanism 2 includes two fixed reinforcing bars 22, both fixedly connected to the top of the base layer 1. A horizontal plate 21 is fixedly connected to the top of the two fixed reinforcing bars 22, and the horizontal plate 21 is connected to the fixed reinforcing bars 22. Multiple circular grooves 23 are provided on the outer side, through which water seeping into the road surface can be discharged. Multiple fixing blocks 24 are fixedly connected to the outer side of the horizontal plate 21. Two curved rods 26 are installed on the outer side of each fixing block 24. The pressure of the road surface can be diffused by the curved rods 26. A first screw 25 is slidably connected to the middle of the fixing block 24. The first screw 25 is threadedly connected to the curved rod 26. A U-shaped rod 27 is provided on the outer side of the horizontal plate 21. Two second screws 28 are slidably connected to the outer side of the U-shaped rod 27. The second screws 28 are threadedly connected to the outer side of the horizontal plate 21. Two support columns 29 are fixedly connected to the top of the U-shaped rod 27. A coarse sand layer 210 is laid on the outer side of the curved rod 26.

[0037] like Figure 3 , Figure 4 and Figure 5As shown, the test track structure of the plant area includes a water collection mechanism 3 comprising two water storage tanks 31, which are fixedly connected to both sides of the drainage ditch 7. The water storage tanks 31 are used to collect rainwater or other water. Two first hollow tubes 32 are fixedly connected to the top of each water storage tank 31. Springs 35 are fixedly connected inside each first hollow tube 32, providing compression and rebound. A sliding plate 33 is fixedly connected to the other end of each spring 35. A moving column 34 is fixedly connected to the end of the sliding plate 33 away from the spring 35. A water collection frame 36 is fixedly connected to the top of the moving column 34. A sponge block 37 is installed inside the water collection frame 36, which can absorb water. A straight groove 315 is opened on the outer side of the water collection frame 36. Multiple connecting hoses 38 are connected to the bottom of the water collection frame 36. The other end of each connecting hose 38 is connected to the top of the water storage tank 31. Most of the excess water... The sponge block 37 can be inserted into the water storage tank 31. The bottom of the water collection frame 36 is fixedly connected to the baffle 39. Since the water collection frame 36 is heavy, it will drive the baffle 39 to move. The outside of the water collection frame 36 is fixedly connected to the pressure pump 311. The input end of the pressure pump 311 is connected to the water inlet pipe 310. The end of the water inlet pipe 310 away from the pressure pump 311 is fixedly connected to the front of the water storage tank 31. The output end of the pressure pump 311 is connected to the water outlet pipe 312. The other end of the water outlet pipe 312 is connected to the second hollow pipe 313. The outside of the second hollow pipe 313 is connected to multiple nozzles 314. When the weather is dry, the residual moisture in the sponge block 37 evaporates, which reduces the weight. The baffle 39 leaves the water inlet pipe 310. The pressure pump 311 draws water into the water outlet pipe 312 and then sprays the water onto the dry road surface through the nozzles 314.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, the test track structure of this plant project includes a multi-layer paving mechanism 4 comprising a first-grade crushed stone layer 41, which is laid on top of the base layer 1. A second-grade crushed stone layer 42 is laid on top of the first-grade crushed stone layer 41. The first-grade crushed stone layer 41 and the second-grade crushed stone layer 42 are used to improve the bearing capacity of the roadbed. A coarse sand layer 210 is laid on top of the second-grade crushed stone layer 42. A gravel-sand mixture layer 45 is laid on top of the coarse sand layer 210. A geogrid 46 is provided in the middle of the composite layer 45. Under the action of vehicle load, the geogrid 45 bears tensile force. Its mesh is interlocked with the gravel mixture layer 46, which transforms the vertical load into a lateral force with a large range and uniform distribution. A cement-stabilized crushed stone layer 43 is laid on top of the gravel mixture layer 45, and a high wear-resistant asphalt concrete layer 44 is laid on top of the cement-stabilized crushed stone layer 43. The geogrid 46 is laid horizontally and is flush with the horizontal plate 21.

[0039] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the test track structure of the plant area has multiple curved grooves 6 inside the water collection frame 36 to allow rainwater accumulated inside the water collection frame 36 to flow smoothly into the water collection frame 36. Multiple connecting plates 5 are fixedly connected inside the water collection frame 36 to fix the sponge block 37. A permeable plate 8 is installed on the top of the drainage ditch 7. The outer side of the drainage ditch 7 is attached to the outer side of the horizontal plate 21. A sliding groove 9 is opened inside the first hollow tube 32. A sliding piece 33 is slidably connected to the inner side of the sliding groove 9 and can move inside the first hollow tube 32. A baffle 39 is slidably connected to the top of the water storage tank 31. The inner bottom wall of the water storage tank 31 is set as an incline to facilitate rainwater to flow down the incline.

[0040] The construction method of the test track structure for the plant project described below can be referred to in correspondence with the test track structure for the plant project described above.

[0041] Please see the appendix Figure 1 - Figure 8 The present invention also provides:

[0042] S1. First, the site is cleaned, lines are drawn and pits are dug. Crushed stone and concrete are mixed and solidified to form base layer 1. The first grade crushed stone layer 41 is laid on the surface of base layer 1 and compacted.

[0043] S2. When pouring the base layer 1, multiple horizontal plates 21 are vertically embedded into the bottom of the foundation pit. The fixing steel bars 22 at the bottom of the horizontal plates 21 are poured together with the base layer 1. After the base layer 1 solidifies, the second grade crushed stone layer 42 is laid on the first grade crushed stone layer 41, the crushed stone cushion is spread and compacted, and half of the coarse sand layer 210 is laid on top of the second grade crushed stone layer 42. The first screw 25 connects and fixes the fixing block 24 to the curved rod 26, and the U-shaped rod 27 is fixed on the horizontal plate 21 by the second screw 28. The support column 29 supports the curved rod 26, and then another part of the coarse sand layer 210 is laid to cover the curved rod 26.

[0044] S3. Add a portion of the gravel mixture layer 45 on top of the coarse sand layer 210, then lay the geogrid 46 horizontally. After laying, add another portion of the gravel mixture and compact it.

[0045] S4. The top of the gravel mixed layer 45 is further reinforced with a cement-stabilized crushed stone layer 43 and cured for a certain number of days. After the cement-stabilized crushed stone layer 43 is laid, a high wear-resistant asphalt concrete layer 44 is laid on the road surface. Then, the flatness control module is used for leveling. The cement is compacted and vibrated, and then the asphalt surface is cured for a period of time.

[0046] S5. Embed the permeable plate 8 between the drainage channels 7, and finally place the preset water collection mechanism 3 on the drainage channel 7.

[0047] The method in this embodiment can be used to execute the above-described runway structure embodiment, and its principle and technical effect are similar, so it will not be described again here.

[0048] Among them, the fixed steel bar 22 is fixed on the horizontal plate 21 and inserted into the base layer 1. The curved rod 26 is placed outside the fixed block 24. The first screw 25 is threaded through the fixed block 24 and connected to the curved rod 26 to fix the position of the curved rod 26. The U-shaped rod 27 is placed in the corresponding position inside the horizontal plate 21. Two second screws 28 are threaded through the U-shaped rod 27 and connected to the threaded hole on the horizontal plate 21 to fix it. Thus, the U-shaped rod 27 is firmly installed on the horizontal plate 21. The two support columns 29 on the U-shaped rod 27 support the curved rod 26. A coarse sand layer 210 is laid on the outside of the fixed curved rod 26.

[0049] Rainwater or other water flows first into the water collection frame 36, where it is absorbed and initially filtered by the sponge blocks 37. As the water volume in the water collection frame 36 increases, its weight increases, causing the moving column 34 at its bottom to press down on the sliding plate 33. The sliding plate 33 compresses the spring 35 inside the first hollow tube 32, causing the water collection frame 36 to descend as a whole. The bottom of the water collection frame 36 is connected to the water storage tank 31 through multiple connecting hoses 38, and some water flows into the water storage tank 31 under the action of gravity. When the weather is dry, the water in the sponge blocks 37 evaporates, causing the sponge blocks 37 to descend. As the water level drops, spring 35 rebounds, causing baffle 39 to rise and not block one end of inlet pipe 310. Water can then flow through the inclined surface inside water collection frame 36 to guide the water into inlet pipe 310. This activates pressurization pump 311, which draws water from storage tank 31 through inlet pipe 310. After pressurization, the water is delivered through outlet pipe 312 to the second hollow pipe 313, where it is finally sprayed out by multiple nozzles 314 to maintain the dry road surface. The straight groove 315 on water collection frame 36 is used to guide overflowing water.

[0050] First, a first-grade crushed stone layer 41 is laid and compacted on top of the base layer 1. Then, a second-grade crushed stone layer 42 is laid and compacted on top of the first-grade crushed stone layer 41. Next, a coarse sand layer 210 is laid and compacted on top of the second-grade crushed stone layer 42. Then, a gravel-sand mixture layer 45 is laid on top of the coarse sand layer 210, and a geogrid 46 is laid and fixed in its middle to enhance structural stability. Under vehicle load, the geogrid 46 is under tension, and its mesh is interlocked with the gravel-sand mixture layer 45, converting the vertical load into a large-scale, uniform lateral force. A cement-stabilized crushed stone layer 43 is laid and compacted on top of the gravel-sand mixture layer 45, and a high-wear-resistant asphalt concrete layer 44 is laid and compacted on top of the cement-stabilized crushed stone layer 43. A paver is used to ensure the smoothness of the runway surface, reduce subgrade stress and uneven settlement, and provide a wear-resistant and anti-skid test surface suitable for high-frequency braking and steering tests.

The support column (29) supports the curved rod (26). Then another part of the coarse sand layer (210) is laid to cover the curved rod (26). S3. Add a portion of the gravel mixture layer (45) on top of the coarse sand layer (210), then lay the geogrid (46) horizontally. After laying, add another portion of the gravel mixture and compact it. S4. The top of the gravel mixed layer (45) is reinforced with cement-stabilized crushed stone layer (43) and cured for a certain number of days. After the cement-stabilized crushed stone layer (43) is laid, the road surface is laid with high wear-resistant asphalt concrete layer (44), and then the flatness control module is used for leveling. The cement is compacted and vibrated, and then the asphalt surface is cured for a period of time. S5. Insert a permeable plate (8) between the drainage channels (7), and finally place the pre-set water collection mechanism (3) on the drainage channel (7).
