Description

Technical Field

[0001] This invention relates to the field of road surface sensor protection equipment technology, and in particular to a road surface internal sensor packaging device and packaging method. Background Technology

[0002] In existing technologies, sensors are protected before being buried in the road surface to safeguard their road performance. One of the most important pre-encapsulation protection measures is reducing the degree of damage to the sensor during construction. Since sensors may move and be damaged during construction, and the survival rate of sensors after road construction cannot be guaranteed, it is necessary to fix and protect the sensors before road construction. Considering that no materials other than road materials should be introduced, road materials are chosen as the mixture to protect the sensors. Existing sensor fixing methods mainly involve molding the sensor into a mixture specimen and placing the specimen on the road surface for simultaneous construction. Commonly used mixture specimen sizes are rectangular. Rectangular molds cannot guarantee the roughness of the specimen while embedding the sensor. Furthermore, placing the sensor in a rectangular specimen exacerbates stress concentration caused by the sensor in the road surface.

[0003] Furthermore, a smooth inner wall of the mold results in low surface roughness of the specimen. The surface roughness of the specimen is affected by the compaction hammer. After being hammered, the low surface roughness makes it difficult to guarantee the adhesion between the specimen and the various structural layers of the pavement when it is subsequently placed in the road surface. Poor adhesion not only affects the accuracy of sensor monitoring but also the stability and durability of the overall pavement structure. If the inner wall of the mold is completely rough, it will make it difficult to move the upper device of the mixture and may also cause leakage of the mixture, thus affecting the compaction effect of the specimen. Summary of the Invention

[0004] To address the shortcomings of existing methods for protecting road sensors, this invention provides a road surface internal sensor encapsulation device and method that embeds sensors and ensures the roughness of the test specimen surface.

[0005] To achieve the above objectives, this invention proposes a road surface internal sensor encapsulation device, comprising: a molding device, a concave-convex compaction part, and a base. The base is detachably connected to the molding device. The molding device has a molding receiving cavity, and the concave-convex compaction part is disposed within the molding receiving cavity. The concave-convex compaction part can slide up and down along the inner wall of the molding device. Encapsulating the road surface internal sensor within a mixture specimen fixes the sensor's position in the road surface, which helps improve the accuracy of subsequent monitoring. The concave-convex compaction part and the molding device make the sides and top surfaces of the mixture specimen containing the sensor uneven, resulting in high surface roughness and improved adhesion between the specimen and the road surface. This, in turn, improves the accuracy of sensor monitoring and prevents damage to the sensor during road construction. The dual protection of the mixture specimen and the road surface for the sensor increases the service life of the road surface internal sensor.

[0006] As an optional implementation, in the road surface internal sensor packaging device provided by the present invention, the molding device includes multiple arc-shaped packaging parts connected end-to-end by connectors. The multiple arc-shaped packaging parts are spliced ​​together to form a complete circular structure with the molding and receiving cavity inside. By setting multiple arc-shaped packaging parts spliced ​​end-to-end, it is easy to demold specimens with uneven surfaces. Demolding is achieved by disassembling the connectors between the multiple arc-shaped packaging parts, making the operation convenient and demolding easy.

[0007] As an optional implementation, in the road surface internal sensor packaging device provided by the present invention, the arc-shaped packaging part includes a connecting clip, a forming concave-convex part, and an arc-shaped flat part arranged sequentially from bottom to top. The connecting clip is detachably connected to the base. The inner wall surface of the forming concave-convex part is uneven, and the concave-convex compaction part can slide up and down along the inner wall of the arc-shaped flat part. The uneven inner wall surface of the forming concave-convex part can make the side surface of the specimen uneven during the sensor packaging process, ensuring good adhesion between the specimen and the road surface structure. The connecting clip serves to position and fix the sensor to the base, preventing the sensor from moving within the forming device.

[0008] As an optional implementation, in the road surface internal sensor packaging device provided by the present invention, each of the arc-shaped packaging parts is provided with connecting ears on both sides. Two adjacent arc-shaped packaging parts are connected by the connecting ears and the connectors inserted into the connecting ears. The connecting ears and the connectors inserted into the connecting ears are provided, wherein the connectors can be bolts. The connecting ears are provided with internal threads. The connectors are screwed into the connecting ears and tightened with nuts to fix them, so as to facilitate the connection of adjacent arc-shaped packaging parts, which is convenient for installation and disassembly and has strong operability.

[0009] As an optional implementation, in the road surface internal sensor packaging device provided by the present invention, wire outlets are provided at two opposite positions at the bottom end of the forming device to facilitate fixing the sensor, thereby fixing the sensor at the bottom position of the forming device and preventing the sensor from moving.

[0010] As an optional implementation, in the road surface internal sensor encapsulation device provided by the present invention, the bottom of the uneven compaction part is uneven. The uneven compaction part can move up and down inside the forming device, which can make the upper surface of the specimen uneven, increase the roughness of the upper surface, and ensure the adhesion between the specimen and the various structural layers of the road surface when the specimen is placed in the road surface, thereby enhancing the adhesion effect, ensuring the accuracy of sensor monitoring, and also ensuring the stability and durability of the overall road surface structure.

[0011] As an optional implementation, in the road surface internal sensor packaging device provided by the present invention, the base is provided with a stepped opening, and the connecting card is disposed in the stepped opening to play a positioning role.

[0012] Preferably, the present invention also provides a packaging method for a road surface internal sensor packaging device based on any of the above-described methods, comprising the following steps:

[0013] S1: Assemble the molding device and the base, place the sensor in the molding cavity of the molding device and on the base, and clip the sensor wire to the wire outlet to fix the sensor at the bottom of the molding device.

[0014] S2: Apply oil to the inner wall of the molding device and the bottom of the concave-convex compaction part, then add the well-stirred mixture to the molding device with the sensor, tamp along the periphery of the molding device until the surface of the mixture is flat, place the concave-convex compaction part into the molding cavity of the molding device and place it above the mixture, fix the molding device together with the base on the compaction table, place the compaction hammer above the concave-convex compaction part in the molding device, start the vibration compaction instrument, and start vibrating and compacting the mixture;

[0015] S3: After the specimen is compacted, remove the base, cure the molding device containing the specimen according to the specimen molding requirements, open the molding device to demold, and thus complete the preparation of the mixed specimen with embedded sensor.

[0016] Compared with the prior art, the beneficial effects of the technical solution of the present invention are as follows:

[0017] I. The road surface internal sensor encapsulation device provided by the present invention comprises a molding device, a concave-convex compaction part, and a base. The base is detachably connected to the molding device. The molding device has a molding receiving cavity, and the concave-convex compaction part is provided within the molding receiving cavity. The concave-convex compaction part can slide up and down along the inner wall of the molding device, encapsulating the road surface internal sensor in the mixture specimen. This fixes the sensor's position in the road surface, which helps improve the accuracy of subsequent monitoring. The concave-convex compaction part and the molding device make the sides and top surfaces of the mixture specimen with the embedded sensor uneven, resulting in high surface roughness. This improves the adhesion between the specimen and the road surface, thereby improving the accuracy of sensor monitoring and preventing damage to the sensor during road construction. The dual protection of the mixture specimen and the road surface for the sensor increases the service life of the road surface internal sensor.

[0018] II. The packaging method of the road surface internal sensor packaging device provided by the present invention encapsulates the sensor in a mixture specimen and embeds it inside the road surface in the form of a specimen. This method can ensure the monitoring accuracy of the sensor. The cylindrical forming device is used, that is, multiple arc-shaped packaging parts are spliced ​​to form a cylindrical structure. Compared with rectangular mixture specimens, the cylindrical mixture specimen and the uneven surface of the specimen ensure good adhesion between the specimen and the road surface, while also reducing the impact on the original road surface structure. It can reduce the stress concentration phenomenon caused by the sensor inside the road surface, making the road surface structure more uniformly stressed. Attached Figure Description

[0030] This invention provides a road surface internal sensor encapsulation device, such as... Figures 1-5As shown, it includes: a molding device 1, a concave-convex compaction part 2, and a base 3. The base 3 is detachably connected to the molding device 1. The molding device 1 has a molding receiving cavity 11, and the concave-convex compaction part 2 is located within the molding receiving cavity 11. The concave-convex compaction part 2 can slide up and down along the inner wall of the molding device 1. Encapsulating the road surface internal sensor in the mixture specimen fixes the sensor's position in the road surface, which helps improve the accuracy of subsequent monitoring. The concave-convex compaction part 2 and the molding device 1 make the sides and top surfaces of the mixture specimen with the embedded sensor uneven, resulting in high surface roughness. This improves the adhesion between the specimen and the road surface, thereby improving the accuracy of sensor monitoring and preventing damage to the sensor during road construction. The dual protection of the mixture specimen and the road surface increases the service life of the road surface internal sensor. Specifically, considering the avoidance of introducing materials other than road materials, road materials are chosen as the mixture to protect the sensor. The road material is a combination of asphalt and stone.

[0031] Furthermore, in the road surface internal sensor packaging device provided by the present invention, the forming device 1 includes a plurality of arc-shaped packaging parts 12 connected end to end by connectors 13. The plurality of arc-shaped packaging parts 12 are spliced ​​together to form a complete circular structure with the forming receiving cavity 11 inside. By setting a plurality of arc-shaped packaging parts 12 spliced ​​end to end, it is convenient to demold specimens with uneven surfaces. Demolding is achieved by disassembling the connectors 13 between the plurality of arc-shaped packaging parts 12, making the operation convenient and demolding easy. Figure 2 In the preferred embodiment shown, the molding device 1 includes three arc-shaped encapsulation parts 12 connected end to end by connectors 13. The three arc-shaped encapsulation parts 12 are spliced ​​together to form a complete circular structure with the molding receiving cavity 11 inside.

[0032] like Figure 2 and Figure 3 As shown, in the road surface internal sensor packaging device provided by the present invention, the arc-shaped packaging part 12 includes a connecting clip part 121, a forming concave-convex part 122, and an arc-shaped flat part 123 arranged sequentially from bottom to top. The connecting clip part 121 is detachably connected to the base 3. The inner wall surface of the forming concave-convex part 122 is uneven. The concave-convex compaction part 2 can slide up and down along the inner wall of the arc-shaped flat part 123. The uneven inner wall surface of the forming concave-convex part 122 can make the side surface of the specimen uneven during the sensor packaging compaction process. The concave-convex compaction part 2 and the forming concave-convex part 122 can make the upper surface and side surface of the specimen uneven, respectively, ensuring that the specimen has good adhesion to the road surface structure. By setting the connecting clip part 121, it plays a role in positioning and fixing with the base 3, which can prevent the sensor from moving inside the forming device 1.

[0033] Preferably, in the road surface internal sensor packaging device provided by the present invention, each of the arc-shaped packaging parts 12 is provided with connecting ears 14 on both sides. Two adjacent arc-shaped packaging parts 12 are connected by the connecting ears 14 and the connectors 13 inserted into the connecting ears 14. By setting the connecting ears 14 and the connectors 13 inserted into the connecting ears 14, wherein the connectors 13 can be bolts, the connecting ears 14 are provided with internal threads, and the connectors 13 are screwed into the connecting ears 14 and tightened with nuts to fix them, it is convenient to connect adjacent arc-shaped packaging parts 12, which facilitates installation and disassembly and has strong operability.

[0034] Furthermore, in the road surface internal sensor packaging device provided by the present invention, wire outlets 15 are provided at two opposite positions at the bottom end of the forming device 1 to facilitate fixing the sensor, so that the sensor is fixed at the bottom position of the forming device 1 and the sensor is prevented from moving.

[0035] like Figure 4 As shown, in the road surface internal sensor encapsulation device provided by the present invention, the bottom of the uneven compaction part 2 is uneven. The uneven compaction part 2 can move up and down inside the forming device 1. The uneven compaction part 2 and the forming uneven part 122 can respectively make the upper surface and side surface of the specimen uneven, increasing the roughness of the upper surface and side surface, so that the specimen can be placed in the road surface to ensure the adhesion between the specimen and the road surface structural layer materials, enhance the adhesion effect, ensure the accuracy of sensor monitoring, and also ensure the stability and durability of the overall road surface structure.

[0036] In addition, such as Figure 5 As shown, in the road surface internal sensor packaging device provided by the present invention, the base 3 is provided with a stepped opening 31, and the connecting card part 121 is disposed in the stepped opening 31 to play a positioning role.

[0037] Preferably, the present invention also provides a packaging method for a road surface internal sensor packaging device based on any of the above-described methods, comprising the following steps:

[0038] S1: Assemble the molding device 1 and the base 3, place the sensor in the molding cavity 11 of the molding device 1 and place it on the base 3, and clip the sensor wire to the wire outlet 15 to fix the sensor at the bottom of the molding device 1.

[0039] S2: Apply oil to the inner wall of the molding device and the bottom of the concave-convex compaction part to facilitate demolding. Then add the well-stirred mixture to the molding device 1 with the sensor. Tamp along the periphery of the molding device 1 until the surface of the mixture is flat. Place the concave-convex compaction part 2 into the molding cavity 11 of the molding device 1 and place it above the mixture. Fix the molding device 1 together with the base 3 on the compaction table. Place the compaction hammer above the concave-convex compaction part 2 in the molding device 1. Start the vibration compaction instrument and start vibrating and compacting the mixture so that the compaction hammer continuously hits the concave-convex compaction part 2 to compact the mixture specimen.

[0040] S3: After the specimen is compacted, remove the base 3, and after the molding device 1 containing the specimen is cured according to the specimen molding requirements, open the molding device 1 to demold, thereby completing the preparation of the mixed specimen with embedded sensor.

[0041] The packaging method of the road surface internal sensor packaging device provided by the present invention encapsulates the sensor in a mixture specimen and embeds the sensor in the form of a specimen inside the road surface. This method can ensure the monitoring accuracy of the sensor. The cylindrical forming device is used, that is, multiple arc-shaped packaging parts are spliced ​​to form a cylindrical structure. Compared with rectangular mixture specimens, the use of cylindrical mixture specimens and the uneven surface of the specimens ensures better adhesion between the specimens and the road surface, while also reducing the impact on the original road surface structure. It can reduce the stress concentration phenomenon caused by the sensor inside the road surface, making the road surface structure more uniformly stressed.
