Description

Technical Field

[0001] This invention relates to the field of colored permeable monolithic pavement, and more specifically to a colored permeable monolithic pavement extrusion molding and paving device. Background Technology

[0002] With the continuous development of urban construction, urban surfaces are increasingly being replaced by buildings and paved roads. While transportation infrastructure has promoted economic development and paved roads have greatly facilitated people's travel, the poor permeability of paved surfaces prevents timely replenishment of groundwater, leading to disruption of the ecological balance. The application of colored permeable pavement and permeable materials plays a crucial role in improving the urban ecological environment and is of great significance for promoting sustainable urban development.

[0003] Currently, the paving of colored permeable pavements mostly relies on primitive paving equipment and manual labor, requiring significant manpower, material resources, and financial investment. Traditional paving methods suffer from the following main problems:

[0004] 1. The impact of human factors on the benchmark: Traditional guiding benchmarks are determined by reading the elevation of the leveling rod with a leveling instrument. However, the roadbed is often poorly constructed, and the accuracy of the benchmark line during its erection depends on the responsibility and fatigue of the personnel. To a large extent, this affects the accuracy of the benchmark guiding line.

[0005] 2. Impact of construction machinery on the benchmark: During the paving process, paving equipment may damage the benchmark piles or material trucks may roll over the benchmark line on the construction site. These factors can lead to deviations in the benchmark setting and errors in the paving construction.

[0006] 3. The density and permeability of colored permeable pavement cannot be guaranteed: The paving construction involves directly pouring the permeable material onto the road surface, and then having the pouring workers spread it. This not only easily leads to uneven spreading of the permeable material on the road surface, but also requires a large amount of work. The permeable material that has been piled up for a long time is not easy to compact, resulting in different performance indicators of the colored permeable pavement and making it impossible to guarantee the compaction density and permeability of the colored permeable pavement.

[0007] 4. Safety hazards during construction: Paving construction is greatly affected by external factors. In order to meet the construction schedule and progress, continuous 24-hour construction work is often required. Due to the fatigue of construction workers, the probability of errors and accidents during construction will inevitably increase, resulting in potential risks to project quality and safety.

[0008] 5. Material control: Due to low control precision and poor quality of subbase treatment, the flatness of the next layer is poor. In order to ensure the thickness of the thinnest part, it will cause waste of materials in the paving of the upper layer. Summary of the Invention

[0009] One objective of this invention is to provide a colored permeable monolithic pavement extrusion molding and paving device. Through a moving mechanism, a feeding structure, and a mold structure, the material is directly input into the mold structure and extruded into the required thickness and size during the movement of the moving mechanism. The pressed material is then directly paved on the ground through the mold structure and the discharge plate, which move with the moving mechanism.

[0010] This objective is achieved using the following technical solution:

[0011] This device includes a moving mechanism, which comprises a main frame and moving wheels. The rotating wheels drive the device to move. The main frame is equipped with a feeding structure and a mold structure. The mold structure includes a material inlet and a material outlet. The material inlet is detachably connected to the outlet of the feeding structure, and the material outlet is detachably connected to one end of an outlet plate. The other end of the outlet plate contacts the ground. In use, material enters the mold structure through the feeding structure. The mold structure compresses the material to the required thickness and width, and finally slides through the material outlet and outlet plate onto the road surface to be paved with colored permeable pavement material. After paving, further curing and maintenance are performed. Because the mold structure is located on the main frame, when the moving mechanism moves, it moves the mold structure and the feeding structure together. During this movement, the compressed colored permeable pavement material is directly extruded from the mold outlet and laid on the ground.

[0012] Compared to existing permeable bricks, this device firstly directly forms a large, monolithic colored permeable pavement using a mold structure, eliminating the need to lay multiple bricks separately, thus saving manpower and resources. Secondly, the colored permeable pavement extruded by the mold structure is not cured; the device only adjusts its thickness, width, and other dimensions, allowing the adjusted pavement to be directly laid on the ground without the need for leveling or calculations based on a baseline, further improving the accuracy of the colored permeable pavement. Thirdly, this device does not require the setting of reference stakes or baselines, therefore, the paving device will not damage or run over reference stakes or baselines during movement.

[0013] Compared to existing manual paving methods, which involve directly pouring permeable material onto the road surface and having workers spread it, this method often results in uneven distribution of the permeable material, is labor-intensive, and the material, when left to accumulate for extended periods, is difficult to compact. This leads to variations in the performance indicators of the colored permeable pavement, failing to guarantee the compaction density and permeability of the overall pavement. This device, however, uses a mold structure to directly extrude the permeable material into the required size. After being laid on the road surface by the discharge plate, it eliminates the need for complex and arduous operations such as layout, piling, and stringing lines, as well as manual spreading. This significantly reduces labor intensity, greatly accelerates construction speed, and prevents uneven spreading, ensuring compaction density and permeability, thereby guaranteeing the quality of the colored permeable pavement paving.

[0014] Furthermore, the mold structure of this device includes a detachably connected upper mold and a lower mold. The upper mold is provided with several vent holes communicating with the interior of the mold structure. The vent holes are connected to a high-pressure injection structure, which is connected to a storage tank for holding the adhesive. The high-pressure injection structure includes several high-pressure nozzles, each connected to a vent hole. During use, the mold structure compacts the material. After compression, the pores of the colored permeable pavement material become smaller, affecting the permeability. The high-pressure injection structure of this device directly injects the adhesive from the storage tank into the colored permeable pavement material within the mold structure through the vent holes. Because the high-pressure injection of the adhesive is from top to bottom, it not only opens up the permeable pores of the colored permeable pavement, ensuring its permeability efficiency and the fusion rate of the base layer, but also positions the adhesive at the lower end of the compacted colored permeable pavement material. When the compacted material contacts the ground, the adhesive enhances the adhesion between the material and the ground. Preferably, several ventilation holes are evenly distributed on the upper mold. These ventilation holes spray more permeable material onto the pressed colored permeable pavement material, thereby improving permeability. Meanwhile, the high-pressure nozzles can better inject the adhesive onto the bottom of the compacted colored permeable pavement material, allowing it to better bond with the ground.

[0015] Furthermore, a fixed structure for placing the reinforcing mesh is provided on the main frame platform. The reinforcing mesh is connected to the lower end of the mold structure. The fixed structure is used to place the reinforcing mesh, which is usually wrapped around the fixed structure. One end of the reinforcing mesh is connected to the lower end of the mold structure. When the material enters the mold structure from the feeding structure, and is extruded from the material outlet of the mold structure after being pressed, the reinforcing mesh moves with the material and then moves to the ground. The addition of the reinforcing mesh to the bottom layer of the colored permeable pavement effectively improves the strength of the colored permeable pavement.

[0016] Preferably, the feeding structure of this device includes a screw propeller and a hopper, with the lower end of the hopper connected to the screw propeller. Material enters the screw propeller through the hopper and is then extruded into the mold structure, achieving continuous material extrusion. As the moving mechanism moves, the material pressed in the mold structure is continuously extruded and laid on the ground. Simultaneously, the feeding structure includes a first control system for controlling the feeding speed. Therefore, the first control system can adjust the density of the pressed colored permeable pavement material in the mold structure by controlling the feeding speed, thereby controlling its strength. The moving mechanism includes a second control system for controlling the moving speed of the device. The first control system of the moving mechanism further controls the moving speed of the device, coordinating with the extrusion speed of the feeding structure to ensure that the pressed colored permeable pavement material is better laid on the ground, guaranteeing the quality of the colored permeable pavement material.

[0017] Preferably, the lower mold and the main frame of this device are detachably connected via an adjustable-length connector. Simultaneously, the material inlet of the mold structure is detachably connected to the outlet of the feeding structure, and the material outlet is detachably connected to one end of the discharge plate. Therefore, during use, mold structures of different sizes can be replaced as needed, expanding the range of applications.

[0018] Preferably, the width of the discharge plate of this device is greater than or equal to the internal width of the mold structure, so that the pre-formed colored permeable pavement material extruded from the mold structure can be directly laid on the ground through the discharge plate, ensuring the paving quality.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] This invention relates to a colored permeable monolithic pavement extrusion molding and paving device. This device effectively reduces the labor intensity of workers, improves the production efficiency of enterprises, saves national resources, and makes the machinery operate more coordinated during construction.

[0021] This device uses a mold structure to extrude colored permeable monolithic pavement material for paving, which can ensure the density, strength and flatness of the colored permeable monolithic pavement. The mold structure and the feeding structure are detachably connected, so colored permeable monolithic pavement of various required widths and thicknesses can be extruded by changing the mold.

[0022] Meanwhile, the high-pressure injection structure sprays the adhesive onto the bottom of the extruded colored permeable pavement through the vent holes. At the same time as the injection, the permeable holes of the colored permeable pavement are opened, which can ensure the permeability efficiency of the colored permeable pavement and the integration rate with the ground base.

[0023] Secondly, this device adds a reinforcing mesh to the bottom layer of the colored permeable pavement material, which can further improve the strength of the colored permeable pavement. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0032] Example 1

[0033] like Figure 1As shown, this device includes a moving mechanism, a feeding structure, and a mold structure. The moving mechanism includes a main frame 1, tracked drive wheels 15, and a driving chamber 14. The feeding structure and the mold structure are mounted on the main frame 1. The mold structure includes a material inlet and a material outlet. The material inlet is detachably connected to the outlet of the feeding structure, and the material outlet is detachably connected to one end of the discharge plate 9. The other end of the discharge plate 9 is in contact with the ground. The material enters the mold structure through the feeding structure and is located on the ground through the discharge plate 9.

[0034] In some embodiments, the feeding structure includes a screw propeller 2 and a hopper 3, with the lower end of the hopper 3 connected to the screw propeller 2. The screw propeller 2 is a conventional structure, including an outer cylinder, a screw rod, and a motor. An inlet end is provided on the side of the outer cylinder, through which material enters the outer cylinder. The motor controls the rotation of the screw rod, which forces the material from the outlet of the outer cylinder into the mold structure. Preferably, the screw propeller 2 is connected to the drive shaft of the moving mechanism; the rotation of the drive shaft further controls the rotation of the screw propeller 2. The hopper 3 is mounted on the screw propeller 2, and a discharge switch is provided on the hopper 3, allowing for further control of the material entering and exiting the hopper 3 during use.

[0035] In some embodiments, the feeding structure can also be other structures, such as a horizontal cylinder with a push plate at one end. The push plate moves along the axis of the cylinder under the drive of the telescopic rod. The upper end of the cylinder is also provided with an inlet end. The material enters the cylinder through the inlet end and moves into the mold structure by the movement of the push plate.

[0036] In one or more embodiments, the feeding structure includes a first control system for controlling the feeding speed. In some embodiments, the first control system is a structure for controlling a motor. The structure and connection relationship are existing structures, and the inventors will not elaborate on them here.

[0037] In one or more embodiments, the moving mechanism includes a second control system for controlling the moving speed of the device. The second control system may be a motor that controls the rotational speed of the moving wheels, or other structures, as long as they can control the walking speed of the moving mechanism.

[0038] During use, the tracked drive wheel 15 or the moving wheel rotates to move the device. The material is placed in the feeding structure and squeezed into the mold structure through the feeding structure. After the mold structure squeezes the material to the required thickness and width, it is laid on the road surface through the material outlet and discharge plate 9 of the mold structure. After the paving is completed, it is cured, maintained and other operations are carried out to obtain the final colored permeable pavement.

[0039] In some embodiments, both the first and second control systems are controlled and adjusted through the cab 14, thereby adjusting the compaction density of the colored permeable pavement material as needed, thus improving the strength and quality of the colored permeable pavement material. A control console is installed in the cab, which controls the rotational speed of the tracked drive wheels and the propeller via a controller. The specific connection method is electrical connection, and the connection structure is an existing structure. In actual use, it can be adaptively adjusted according to the actual structure.

[0040] In some embodiments, the rotational speed of the screw propeller is the same as that of the tracked drive wheel. When the screw propeller rotates, it forces the colored permeable pavement material into the mold structure and out through the mold structure into the discharge plate. Before the material reaches the ground, the tracked drive wheel begins to move. That is, as the tracked drive wheel moves, the colored permeable pavement material is just squeezed out of the discharge plate and contacts the ground. The movement of the tracked drive wheel then lays the colored permeable pavement material on the ground. A controller is installed on the control panel in the driver's cab. The controller is connected to both the first and second motors. The control panel controls the rotational speed and switching of the first and second motors respectively.

[0041] In one or more embodiments, the angle between the discharge plate 9 and the ground is 30 degrees, which is more conducive to the sliding of the colored permeable pavement material onto the ground for paving.

[0042] Example 2

[0043] In some embodiments, the mold structure includes a detachably connected upper mold 4 and a lower mold 5, which are connected by bolts, such as... Figure 2 As shown, the upper mold 4 and the lower mold 5 are connected to form a material inlet at one end and a material outlet at the other end. The material inlet is bolted to the outlet of the feeding structure, and the material outlet is bolted to one end of the discharge plate 9. The other end of the discharge plate 9 is in contact with the ground. The upper mold 4 is provided with several vent holes 6 that communicate with the interior of the mold structure. The high-pressure injection structure includes several high-pressure nozzles 7, which are respectively connected to several vent holes 6. The high-pressure injection structure is connected to the storage tank 12 for holding the adhesive.

[0044] During use, the feeding structure squeezes the material into the mold structure. After being squeezed by the mold structure, the material is squeezed out from the material outlet of the mold structure to form colored permeable pavement material of the required size. Then, it slides onto the ground through the discharge plate 9 and, in conjunction with the movement of the moving mechanism, lays the colored permeable pavement material on the ground.

[0045] In one or more embodiments, the storage tank 12 is installed above the screw propeller 2. The storage tank 12 is connected to the air pump 13 in the power unit of the moving mechanism via a high-pressure air pipe 11. The storage tank 12 is then connected to the high-pressure nozzle 7 via the high-pressure air pipe 11 and a solenoid valve 10. The high-pressure nozzle 7 is aligned with the vent hole 6 on the mold structure, forming a high-pressure injection structure. In use, the air pump 13 pressurizes the adhesive in the storage tank 12 into the high-pressure air pipe 11, and then sprays it into the mold structure through the high-pressure nozzle 7. This creates several permeable holes in the initially formed colored permeable pavement material, and the adhesive is applied directly to the lower end of the initially formed colored permeable pavement material for better bonding with the ground.

[0046] In some embodiments, the structure between the solenoid valve 10 and the high-pressure nozzle 7 is as follows: Figure 3 As shown, high-pressure nozzles 7 are evenly distributed above the mold structure. There are four parallel high-pressure air pipes 11, and each high-pressure air pipe 11 is connected to four high-pressure nozzles 7. Each high-pressure nozzle 7 is connected to a ventilation hole 6 of the mold structure.

[0047] Example 3

[0048] Based on the above embodiment, the main frame 1 is provided with a fixing structure for placing the reinforcing mesh 8. The fixing structure includes a vertical connecting rod and a horizontal rotating rod. One end of the connecting rod is connected to the main frame 1, and the other end of the connecting rod is connected to the rotating rod. The rotating rod can rotate circumferentially on the connecting rod. One end of the reinforcing mesh 8 is fixed on the rotating rod. The reinforcing mesh 8 is rolled into a roll. At the same time, the other end of the reinforcing mesh 8 is on the lower end of the mold structure. When the material is squeezed in the mold structure, the material can drive the reinforcing mesh 8 to move together as it is squeezed out of the mold structure, and then lay it on the ground.

[0049] Example 4

[0050] Based on the above embodiments, the lower mold 5 and the main frame 1 are detachably connected by an adjustable connector. In this embodiment, the lower mold 5 and the main frame 1 are connected by an adjusting bolt. The adjusting bolt includes a connecting plate that is bolted to the main frame 1. The connecting plate is provided with an adjusting bolt, and the distance between the lower mold 5 and the main frame 1 is adjusted by adjusting the adjusting bolt.

[0051] The feeding structure is connected to the main frame 1 by adjusting bolts. Specifically, the screw propeller 2 is connected to the main frame 1 by adjusting bolts.

[0052] The discharge plate 9 is connected to the main frame 1 by adjusting bolts, and the discharge plate 9 is connected to the material outlet of the mold structure.

[0053] Example 5

[0054] Based on the above embodiments, the colored permeable pavement material and adhesive in hopper 3 are existing materials. This device directly loads the colored permeable pavement material into the hopper so that it enters the screw propeller. The adhesive is also directly loaded into the storage tank so that it is sprayed into the colored permeable pavement material under high pressure. This device does not improve its composition or preparation method. It simply uses this device to directly extrude the colored permeable pavement material that needs to be laid manually into the required size.

[0055] When in use, if the road surface is wide, the internal width of the mold structure of this device can be set to half the width of the road surface. When laying the colored permeable pavement material with the correct width and thickness, this device can be moved twice on the road surface. The first time, half the width of the road surface is laid with colored permeable pavement material, and the second time, half the width of the road surface is laid again, finally obtaining a fully laid colored permeable pavement material.

[0056] The term “connection” as used herein, unless otherwise specified, can mean a direct connection or an indirect connection via other components.

[0057] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
