Description

Technical Field

[0001] This invention relates to a maintenance device and method, and more particularly to a maintenance device and method for airport cement concrete pavement. Background Technology

[0002] Airport concrete pavement construction employs a skip-pile method. The pavement concrete thickness is typically 32cm, 38cm, 40cm, or 42cm, while the shoulder concrete thickness is generally 14cm. The main pavement block dimensions are 5×5m, 5×4.5m, and 5×4.0m, while the main shoulder block dimensions are 2.5m×2.5m. The typical construction length for a single pavement block is 100m, 120m, or 150m, and for a single shoulder block, it is typically 200m or 300m. After concrete construction, once the surface has reached a certain hardness (no indentation when lightly pressed with a finger), geotextile fabric can be covered, and water curing can begin to maintain a moist surface. After approximately 12 hours of curing, a joint cutter is used to cut joints to prevent temperature cracking. In the current construction process for concrete curing and geotextile laying, the width of a purchased roll of geotextile can be produced according to the pavement width requirements, and the length is generally up to 150m. During laying, the entire roll of geotextile is often cut according to the dimensions of the concrete pavement sections, and then manually transported to the pavement for laying. During the laying process, each section can only be laid manually, overlapping and splicing. After about 12 hours of curing, the geotextile sections are uncovered, and a cutting machine is used to cut seams according to the pavement section dimensions to form temperature expansion joints. Because it requires manual laying of individual geotextile sections, the curing efficiency of airport cement concrete pavements is affected. Existing construction methods require cutting and overlapping the curing fabric according to the slabs, resulting in waste of materials. Furthermore, the overlapping areas are easily blown away by the wind, causing localized areas of the concrete pavement to fail to maintain a moist state, leading to inadequate curing. There is currently no suitable curing device for in-depth curing of temperature cracks. This invention, through its technical feature of continuous, integrated fabric covering of airport concrete pavement, effectively explores and studies the technical problems of manually transporting geotextiles to the pavement for laying, and the fact that the laying process can only be carried out manually by overlapping and splicing individual pieces. The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on February 11, 2023, which addresses practical technical problems encountered during the work process, and the existing technical problems, technical features, and technical effects in similar patent documents and background information obtained through retrieval, the technical solution of this invention is proposed.

[0042] The technical effects of the above technical solutions are: highlighting the technical characteristics of overall continuous coverage treatment of airport cement concrete pavement, and introducing its application in the technical field of maintenance methods for airport cement concrete pavement.

[0043] The present invention is designed with the following steps: When curing airport concrete pavement, a channel-shaped steel bar is placed on both sides of the airport concrete pavement, a first rotating wheel is placed inside the channel-shaped steel bar, a pressing roller and a rotating roller are placed on the airport concrete pavement, and a curing geotextile is rolled onto the central shaft. Then, the rotating pressure seat is flipped inward in the U-shaped groove of the column located on the first support wheel. The central shaft is lifted using the first and second rotating handles. The end of the central shaft is then placed into the arc-shaped groove of the rotating support. The rotating pressure seat is flipped outward in the U-shaped groove of the column located on the first support wheel. The arc-shaped groove of the rotating pressure seat is installed on the end of the central shaft. The first and second rotating handles are then used to lift the central shaft. Rotate the handle to allow the central shaft to rotate within the arc-shaped grooves of the rotating support and the rotating pressure seat, releasing the geotextile fabric located on the central shaft. Place the geotextile fabric between the pressing roller and the rotating roller, positioning the pressing roller on the upper end face of the geotextile fabric and the rotating roller on the lower end face. Separate the connecting screw from the middle of the upper end face of the arm. Place the shim between the middle of the upper end face of the arm and the inner wall of the horizontal section of the seat to adjust the distance between the horizontal sections of the arm and the seat. Connect the connecting screw back to the middle of the upper end face of the arm, causing the first rotating wheel to move within the channel steel and the second rotating wheel to move on the airport concrete pavement. Simultaneously, the first and second rotating handles are activated. The central shaft rotates within the arc-shaped grooves of the rotating support and the rotating pressure seat, releasing the geotextile from the central shaft. The pressure roller then lays the geotextile on the airport's concrete pavement. After laying the geotextile, the rotating pressure seat is flipped inwards in the U-shaped groove of the column on the first support wheel. Using the first and second rotating handles, the central shaft is lifted off the rotating support, and the arm is flipped inwards on the column on the first support wheel. The mounting hole is aligned with the elongated hole, and the connecting bolts and nuts are installed in the elongated hole and the mounting hole. This separates the pressure roller and rotating roller from the geotextile. The high-pressure water pipe is placed on the crossbeam, and the plug bolt is separated from the water inlet pipe. The outer end of the pressure water pipe is connected to the outer end of the inlet pipe, ensuring communication between the high-pressure water pipe and the spray pipe. The first rotating wheel then moves in the opposite direction within the channel steel, spraying water onto the geotextile. After spraying the geotextile, the high-pressure water pipe and spray pipe are closed. The outer end of the high-pressure water pipe is then disconnected from the inlet pipe, and the plug bolt is connected to the inlet pipe. After curing the airport concrete pavement, the central shaft is installed in the arc-shaped groove of the rotating support and the arc-shaped groove of the rotating pressure seat. The end of the geotextile is placed on the central shaft. The central shaft rotates within the arc-shaped grooves of the rotating support and the rotating pressure seat using the first and second rotating handles.The first rotating wheel moves within the channel-shaped steel bar, winding the geotextile fabric onto the central shaft.

[0044] The technical effect of the above solution is that it enables the setting of geotextile covering for the maintenance of airport cement concrete pavement.

[0045] The present invention comprises the following steps: When curing the airport concrete pavement, after twelve hours of curing, a temperature expansion joint is formed on the pavement. Using a holding rod, a support rod is lifted, and an embedded plate is placed on the expansion joint. The support rod is then lowered and placed back onto the pavement, thus installing the embedded plate within the expansion joint. The holding rod is then separated from the support rod, and a geotextile is covered over it. When water is sprayed onto the geotextile, the moisture enters the expansion joint through the support rod and the embedded plate, providing moisture curing to the inner wall of the expansion joint. After curing the pavement, the geotextile is rolled up from the pavement. The holding rod and support rod are then connected, and the support rod is lifted using the holding rod to remove the embedded plate from the expansion joint.

[0046] The technical effect of the above solution is that it enables the setting of water-guiding maintenance operations for temperature expansion joints.

[0047] In this technical solution, the drum shaft is the basic component and an essential technical feature of the invention. The frame, first support leg wheel, rotating support, rotating pressure seat, second support leg wheel, tie rod, rotating shaft, swing arm, press roller, rotating roller, follower wheel, connecting screw, gasket, sprinkler pipe, connecting beam, push handle, embedded plate, support rod, and gripping rod are functional components that enable other technical effects of the invention. The design of the first vertical beam, second vertical beam, crossbeam, drag ear seat, mounting hole, rotating hole, column, first rotating ear seat, second rotating ear seat, first rotating wheel, central shaft, first rotating handle, second rotating handle, arm, elongated hole, seat, second rotating wheel, water spray pipe, water inlet pipe, and plug bolt are technical features that comply with the Patent Law and its implementing regulations.

[0048] In this technical solution, the mobile vehicle device and the roller shaft for integral continuous covering treatment of airport cement concrete pavement are important technical features. In the technical field of maintenance devices and methods for airport cement concrete pavement, this solution is novel, inventive and practical.

A first rotating wheel 24 is placed inside the channel-shaped steel bar. A pressing roller 9 and a rotating roller 91 are placed on the pavement. A geotextile is rolled onto the central shaft 51. Then, the rotating pressure seat 4 is flipped inwards in the U-shaped groove of the column 21 located on the first support leg 2. The first rotating handle 5... 2. Using the second rotating handle 53, the central shaft 51 is lifted, and then the end of the central shaft 51 is placed into the arc-shaped groove of the rotating support 3. The rotating pressure seat 4 is flipped outward in the U-shaped groove of the column 21 located on the first support wheel 2, and the arc-shaped groove of the rotating pressure seat 4 is installed on the end of the central shaft 51. Through the first rotating handle 52 and the second rotating handle 53, the central shaft 51 is moved between the arc-shaped groove of the rotating support 3 and the arc-shaped groove of the rotating pressure seat 4. Rotate the roller to release the geotextile on the central shaft 51, place the geotextile between the pressing roller 9 and the rotating roller 91, so that the pressing roller 9 is positioned on the upper end face of the geotextile and the rotating roller 91 is positioned on the lower end face of the geotextile, thus separating the connecting screw 93 from the middle part of the upper end face of the arm 81. Place the shim 94 between the middle part of the upper end face of the arm 81 and the inner wall of the horizontal part of the seat 921 to adjust the distance between the horizontal parts of the arm 81 and the seat 921. The connecting screw 93 is connected to the middle part of the upper end face of the arm 81, causing the first rotating wheel 24 to move in the channel steel and the second rotating wheel 922 to move on the airport cement concrete pavement. At the same time, through the first rotating handle 52 and the second rotating handle 53, the central shaft 51 rotates in the arc-shaped groove of the rotating support 3 and the arc-shaped groove of the rotating pressure seat 4. The geotextile is released from the central shaft 51 and laid on the airport cement concrete pavement by the pressing roller 9. After the geotextile is laid, the rotating pressure seat 4 is flipped inward in the U-shaped groove of the column part 21 located on the first support wheel 2. The central shaft part 51 is lifted off the rotating support seat 3 via the first rotating handle part 52 and the second rotating handle part 53, causing the arm part 81 to flip inward on the column part 21 located on the first support wheel 2. The mounting hole 15 is aligned with the elongated hole 82. The connecting bolts and nuts are installed in the elongated hole 82 and the mounting hole 15, separating the pressure roller 9 and the rotating roller 91 from the geotextile.

After spraying water onto the geotextile, close the high-pressure water pipe and the spray pipe 951, separate the high-pressure water pipe from the outer end of the inlet pipe 952, and connect the plug bolt 953 to the inlet pipe 952. After the maintenance of the airport concrete pavement is completed, the central shaft 51 is installed in the arc-shaped groove of the rotating support 3 and the arc-shaped groove of the rotating pressure seat 4. The end of the geotextile is placed on the central shaft 51.

The end face of the support rod 20 is configured to be threadedly connected to the gripping rod 30. The embedded plate 10 is configured as a rectangular sheet, the support rod 20 is configured as a circular shaft, and the gripping rod 30 is configured as a circular rod.

[0091] Its technical purpose is to serve as a component for the maintenance of temperature expansion joints.

[0092] A method for curing airport concrete pavement includes the following steps: After twelve hours of curing, a temperature expansion joint is formed on the airport concrete pavement. Using a holding rod 30, a support rod 20 is lifted, and an embedded plate 10 is placed on the temperature expansion joint. The support rod 20 is then lowered and placed back onto the airport concrete pavement, thus installing the embedded plate 10 within the temperature expansion joint. The holding rod 30 is then... The support rods 20 are separated, and the curing geotextile is covered on the support rods 20. When water is sprayed on the curing geotextile, the curing water enters the temperature expansion joint through the support rods 20 and the embedded plate 10, and the inner wall of the temperature expansion joint is cured with water. After the curing of the airport cement concrete pavement is completed, the curing geotextile is rolled up from the airport cement concrete pavement. The holding rod 30 is connected to the support rod 20. By holding the holding rod 30, the support rod 20 is lifted and the embedded plate 10 is taken out from the temperature expansion joint.

[0093] In verifying this invention, the inventors abandoned the existing technical features of manually transporting geotextiles to the pavement and laying them piece by piece manually. Instead, they first proposed a technical feature of continuous, integrated geotextile coverage for airport concrete pavements. This resulted in the first unexpected technical effect: ensuring the integrity of the geotextile's performance and extending its service life. The second unexpected technical effect: achieving full-coverage maintenance of airport concrete pavements. The third unexpected technical effect: enabling water film injection for maintenance in temperature expansion joints.

[0094] In a second embodiment of the present invention, the mobile vehicle device and the roller shaft 5 are interconnected in a manner that performs a continuous, integrated covering treatment on the airport's cement concrete pavement.

[0099] In this embodiment, a third accessory device is also included and is disposed on the mobile vehicle device. The third accessory device is configured to include a water spray pipe 95 and a connecting beam 96.

[0100] In this embodiment, a fourth accessory device is also included and disposed in the temperature expansion joint. The fourth accessory device is configured to include an embedded plate 10, a support rod 20, and a gripping rod 30.

[0101] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the mobile vehicle device realizes the motion support of the roller shaft 5, and the roller shaft 5 realizes the rolling and unrolling or rolling and retracting of the geotextile, thereby realizing the overall continuous fabric covering treatment on the airport cement concrete pavement.

[0102] The second embodiment of the present invention is based on the first embodiment.

[0103] This invention has the following characteristics: 1. Due to the design of the mobile vehicle device and the roller shaft 5, the mobile vehicle device enables the movement support of the roller shaft 5, and the roller shaft 5 enables the winding and unwinding or winding and unwinding of the geotextile. This achieves the overall continuous coverage treatment of the airport cement concrete pavement, solving the technical problem of manually transporting the geotextile to the pavement for laying and having to lay it piece by piece manually during the laying process. Therefore, the construction efficiency of the maintenance of the airport cement concrete pavement is improved.

[0104] 2. By designing the frame 1, the first support wheel 2, the rotating support 3, the rotating pressure seat 4, the second support wheel 6, the tie rod 98, the rotating shaft 7, and the push handle 97, a multi-wheel support vehicle setup is achieved.

[0105] 3. Due to the design of the swing arm 8, the pressing roller 9 and the rotating roller 91, the geotextile can be shaped.

[0106] 4. Due to the design of follower wheel 92, connecting screw 93 and washer 94, rolling support setting of swing arm 8 is realized.

[0107] 5. Due to the design of the sprinkler pipe 95 and the connecting beam 96, watering operations can be carried out on the geotextile for curing.

[0108] 6. Due to the design of the embedded plate 10, support rod 20 and holding rod 30, the maintenance of temperature expansion joints is realized.

[0109] 7. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of this numerical range has achieved very good technical effect.

[0110] 8. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.
