Description

Technical Field

[0001] This invention relates to the field of airport pavement technology, and more particularly to a prefabricated pavement and its implementation method. Background Technology

[0002] Airports, as vital infrastructure for air transport and cities, play an increasingly important role in the integrated transportation system. Airport pavement construction is related to geological and climatic conditions and presents significant challenges due to natural disasters and temperature variations. Furthermore, airport renovations and expansions, as well as runway pavement maintenance, generally require uninterrupted construction, resulting in short effective construction time and long project durations.

[0003] The existing pavement construction process is as follows: surveying and setting out → formwork erection → laying geotextile → concrete pouring → roughening → formwork removal → joint cutting → curing. The pavement can only be put into use after it reaches its design strength. This results in a long construction period, significant disruption to airport operations, and construction quality that is greatly affected by natural conditions. Furthermore, its application in airport reconstruction, expansion, or maintenance has considerable limitations. Summary of the Invention

[0012] Based on the same inventive concept, the present invention also provides a method for processing the above-mentioned prefabricated pavement, comprising the following steps: Step 1: Clean the mold platform and apply release agent to the inner surface of the mold; Step 2: Install the steel reinforcement cage, transverse joint strips of the positive plate, transverse embedded steel bars of the positive plate, longitudinal joint strips of the positive plate, and longitudinal embedded steel bars of the positive plate at the corresponding positions; Step 3: Pour the concrete and vibrate it to shape; Step four: After pouring, steam cure the concrete; complete the processing of the slab pavement. Perform the machining of the negative plate surface according to the above steps; machining is complete.

[0013] Based on the same inventive concept, the present invention also provides a method for assembling the above-mentioned prefabricated pavement, comprising the following steps: Step 1: Lay geotextile on the base layer; Step 2: Assemble n positive slabs and m negative slabs in an alternating manner, where m+1=n; Step 3: After assembling a unit, level each positive and negative runner surface; Step four: After leveling, install the first and second connectors; then perform grouting to complete the construction of one unit. Complete the assembly of the remaining units following the steps described above.

[0014] Based on the same inventive concept, the present invention also provides a method for repairing roads, using the aforementioned prefabricated pavement, comprising the following steps: Step 1: Remove the damaged pavement, clean the top surface of the base layer, and control its flatness; Step 2: Prefabricate the negative slab surface and the second transverse joint frame strip in the factory; Step 3: The old pavement panel is regarded as the positive pavement panel. The first transverse joint frame strip is installed, wherein the transverse joint strip of the positive pavement panel is connected to the transverse pre-embedded steel bars of the positive pavement panel in the factory. On the old pavement panel, holes are drilled at the corresponding positions of the transverse pre-embedded steel bars of the positive pavement panel to form the pre-embedded steel bar holes of the old pavement panel. Rebar anchoring adhesive is injected into the pre-embedded steel bar holes of the old pavement panel. The transverse pre-embedded steel bars of the positive pavement panel are installed into the pre-embedded steel bar holes of the old pavement panel and connected to the old pavement panel by rebar anchoring adhesive.

[0015] Compared with related technologies, the beneficial effects of the present invention are as follows: I. This invention can ensure a stable connection between adjacent pavement panels and a strong load-bearing capacity at the joints. Second, this invention uses a male plate joint frame strip and a female plate joint frame strip to overlap vertically. The bolt holes on the joint frame strip correspond one-to-one to form a complete bolt hole. High-strength bolts are installed at each bolt hole position, which can quickly and effectively realize the joint connection of adjacent male plates and female plates. Moreover, it is not easy to deform or shift after assembly. It can be put into use immediately after assembly without maintenance, thus shortening the construction and operation cycle. Third, this invention improves the overall integrity of the assembled pavement panels and enhances the pavement's resistance to deformation by installing longitudinal and transverse joint frame strips on each pavement panel and locking adjacent pavement panels together directly through the joint frame strips. Fourth, the joint frame structure of the present invention uses high-strength materials to protect the precast concrete pavement slab, enhance the edge strength and corner strength of the pavement slab, reduce the occurrence of pavement defects such as misalignment, corner chipping, and cracks, and extend the service life of the pavement slab. 5. The male plate joint frame used in this invention is in contact with the ground, but the bolt holes do not penetrate the height of the frame, so that the bottom of the frame is closed, which can prevent ground water from directly contacting the bolts, avoid water accumulation and bolt corrosion, and improve the effectiveness of the joint structure. VI. The longitudinal joint frame strip used in this invention is longer than the longitudinal length of the panel. The distance from the edge of the panel on both sides is equal to the width of the transverse joint frame strip of the adjacent positive panel. The extended part is a sloping plane, which can facilitate quick docking with the adjacent joint frame strip. This can further reduce the misalignment between adjacent panels. At the same time, an automatic leveling bolt can be set at the bottom of the docking joint to achieve quick leveling of the precast panel after splicing. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] like Figure 1 As shown, the prefabricated pavement provided in this embodiment includes a male pavement surface 1, a female pavement surface 2, a first connector 3, and a second connector 4. There are multiple male pavement surfaces 1 and multiple female pavement surfaces 2. The multiple male pavement surfaces 1 and the multiple female pavement surfaces 2 are spliced ​​together in a crisscross pattern.

[0023] The male plate joint frame used in this invention is in contact with the ground, but neither the first mounting hole 13 nor the second mounting hole 15 penetrates the height of the frame, so that the bottom of the frame is in a closed state, which can prevent ground water from directly contacting the bolts, avoid water accumulation and bolt corrosion, and improve the effectiveness of the joint structure.

[0024] The two ends of the transverse joint strip 121 of the positive plate are flat, and the two ends of the longitudinal joint strip 141 of the positive plate extend to the outer side of the positive plate panel 11. The interior of the extension to the outer side is connected to the flat surface of the two ends of the transverse joint strip 121 of the positive plate. The exterior of the extension to the outer side is provided with a first inclined surface 1411.

[0027] The second longitudinal joint frame 24 includes a longitudinal joint strip 241 for the negative plate and a plurality of longitudinal embedded steel bars 242 for the negative plate connected to one side of the longitudinal joint strip 241. The longitudinal embedded steel bars 242 are embedded inside the negative plate panel 21. The longitudinal joint strip 241 is a high-strength steel profile that extends horizontally from the upper side of the negative plate panel 21. A plurality of fourth mounting holes 25 (threaded holes) are spaced apart on the longitudinal joint strip 241. The fourth mounting holes 25 are countersunk holes that penetrate the longitudinal joint strip 241.

[0028] The two ends of the transverse joint strip 221 of the negative plate are flat. The two ends of the longitudinal joint strip 241 of the negative plate extend to the outer side of the negative plate panel 21. The inner side of the extension to the outer side is connected to the flat side of the two ends of the transverse joint strip 221 of the negative plate. The outer side of the extension to the outer side is provided with a second inclined surface 2411. The second inclined surfaces 2411 at both ends of the same longitudinal joint strip 241 of the negative plate are arranged in a figure-eight shape.

[0029] like Figure 8 , Figure 9 As shown, the transverse joint strip 221 of the female plate on the female plate surface 2 and the transverse joint strip 121 of the male plate on the male plate surface 1 are connected vertically. Multiple first mounting holes 13 and multiple third mounting holes 23 are aligned one-to-one and connected by a first connector 3. The first connector 3 is a bolt made of high-strength material.

[0030] like Figure 10 , Figure 11 As shown, the longitudinal joint strip 241 of the female plate on the female plate surface 2 and the longitudinal joint strip 141 of the male plate on the male plate surface 1 are connected vertically by overlapping. Multiple second mounting holes 15 and multiple fourth mounting holes 25 are aligned one-to-one and connected by second connectors 4. The second connectors 4 are bolts made of high-strength material. The adjacent first inclined surfaces 1411 and adjacent second inclined surfaces 2411 can be easily connected, reducing misalignment between adjacent plates, and the bottom plate of the connection joint can be equipped with leveling bolts for leveling.

[0031] like Figure 12 As shown, the construction method for prefabricated pavement provided by the present invention includes the following steps: S1, Factory Prefabrication S1.1 Clean the mold platform and apply release agent to the inner surface of the mold.

[0032] S1.2, Install the transverse joint strip 121, the transverse embedded steel bar 122, the longitudinal joint strip 141, and the longitudinal embedded steel bar 142 of the positive plate at the corresponding positions.

[0033] S1.3, pour concrete and vibrate it to shape.

[0034] S1.4 After pouring, steam cure the concrete. Once the concrete strength and curing time meet the design requirements of the construction drawings, mark the pavement panel information, such as positive or negative slabs, longitudinal or transverse joints. Complete the processing of positive slab pavement 1.

[0035] S1.5, Perform quality inspection on the positive plate surface 1. The dimensional control accuracy of the positive plate surface 1 is ≤2mm, and the surface flatness of the positive plate panel 11 is ≤2mm.

[0036] S1.6, Process and inspect the negative slab surface 2 according to the above steps. Store and load the qualified positive slab surface 1 and negative slab surface 2 onto trucks and transport them to the construction site.

[0037] S2, Transportation: Rubber sleeves are used to package and protect the edges and corners of the male and female runners 1 and 2 before transporting them to the installation site.

[0038] S3, on-site installation: S3.1, Controlling the flatness of the top surface of the base layer. S3.1.1, Lay geotextile on the base layer or leave a 3cm thick fast-setting high-strength cement mortar leveling layer.

[0039] S3.1.2, using BeiDou, GPS, RTK technology, or existing well-defined leveling points, determine the elevation control benchmark point for the paving surface. Install a laser transmitter with automatic point-to-point and automatic leveling functions at this point. This laser transmitter can provide millimeter-level elevation references to a laser receiver hundreds of meters away. The laser receiver is connected to the control box on the paver, providing precise elevation information to control the paver to carry out paving work according to the corresponding elevation control requirements. The flatness of the base layer surface is controlled within -5mm, and the surface elevation is controlled within -3mm.

[0040] S3.2 uses two 150t truck cranes, erected on both sides of the runway longitudinally, with the lifting operation radius covering half the width of the runway. The cranes are assembled in units of 3×3 (5 positive plates and 4 negative plates are staggered, for a total of 9 plates), from both sides of the runway toward the middle.

[0041] S3.3, Level the assembled positive plate surface 1 and negative plate surface 2. S3.3.1 An automatic leveling device (including a servo motor and leveling bolts) is installed below the end of the joint frame strip of the precast slabs to be leveled (positive slab surface 1 and negative slab surface 2). The positioning data of the precast slab is determined by the vehicle-mounted Beidou navigation and positioning receiver and sent to the control host. The control host determines the number of the precast slab based on the positioning data, and then sends the elevation information of the four corner points of the precast slab to the total station.

[0042] S3.3.2 After receiving data and instructions, the total station measures the elevation and other measurement data of the four corner points of the precast slab and transmits the survey data to the control host in real time. The control host calculates the difference between the actual elevation and the design elevation of the four corner points of the precast slab based on the measurement data and determines the height adjustment required for the four corners of the precast slab.

[0043] S3.3.3, the control host sends the height adjustment instructions of the four corner points of the precast slab to be adjusted to the servo motor of the leveling device. The servo motor rotates the leveling bolts according to the time sequence and height requirements to realize the elevation adjustment of the four corner points of the precast slab (the specific leveling method is the same as the Chinese patent with authorization announcement number CN1114293427B).

[0044] S3.4 After leveling, install the first connector 3 and the second connector 4. Then perform grouting to complete the construction of one unit. Complete the assembly of the remaining units by following the above steps.

[0045] like Figure 17 As shown, the present invention also provides a pavement repair method, comprising the following steps: S1, Demolish the damaged pavement. Clean the top surface of the base layer and control its flatness. To meet the requirements of rapid paving while reducing grouting, a 3cm thick layer of quick-setting high-strength cement mortar or geotextile is left between the pavement slab and the base layer before on-site assembly of the pavement slab. The old pavement slab is then constructed on-site as follows: Figure 13 The structure shown.

[0046] S2, factory-prefabricated negative slab surface 2 (e.g.) Figure 14 (as shown) and the second transverse joint frame strip 22.

[0047] S3, On-site assembly: The old pavement panel 11' is regarded as the positive pavement panel 11 of the positive pavement surface 1, such as Figure 15 , Figure 16 As shown, the first transverse joint frame strip 12 is installed, wherein the transverse joint strip 121 of the slab and the transverse embedded steel bar 122 of the slab are connected at the factory. Holes are drilled at corresponding positions on the slab's transverse embedded steel bar 122 to form embedded steel bar holes 61 in the old pavement surface. Rebar adhesive 62 is injected into the embedded steel bar holes 61. The transverse embedded steel bar 122 of the slab is then installed into the embedded steel bar holes 61 in the old pavement surface, and the connection to the slab's slab is completed using the rebar adhesive 62.

[0048] S4. Level the precast slab according to the assembly method described above.

[0049] S5. Grouting is performed according to the above assembly method to complete the pavement repair.

[0050] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
