Description

Technical Field

[0001] The invention belongs to the technical field of concrete pavement construction, and particularly relates to a concrete pavement leveling system for a container yard. Background Art

[0002] During the concrete pouring construction, it is necessary to control the flatness and elevation error of the concrete surface. In the traditional concrete pouring process, generally, mortar cakes are made on the ground. During pouring, the top surface of the mortar cake is used as a reference surface and leveled with a straightedge. Although this method is simple, the vibrating rod used during the vibrating process will generate strong vibrations. Due to the limited adhesion force between the mortar cake and the ground, the vibration of the vibrating rod is likely to cause the "displacement" of the mortar cake. Construction workers are likely to step on the mortar cake when entering and exiting during construction. These two situations will change the originally set position of the mortar cake, resulting in the flatness and elevation exceeding the error or having a greater deviation, affecting the visual quality of the concrete surface, and even more affecting the subsequent use function of the pavement and the overall acceptance.

[0003] The area of the container yard is large, and the single-layer area during concrete pouring is large. Using the mortar cake method is likely to result in the same elevation only around the concrete floor, and it is impossible to effectively control the flatness of the middle part of the concrete pavement, with low reliability.

[0027] Please refer to Figures 1 to 10 , and a concrete pavement leveling system provided by the present invention will now be described. A concrete pavement leveling system includes a dividing unit 1, a leveling assembly 2, an elevation assembly 3, and a plurality of scraping assemblies 4. The dividing unit 1 includes a plurality of first partitions 11 arranged at intervals in the transverse direction and a plurality of second partitions 12 arranged at intervals in the longitudinal direction. The first partitions 11 extend in the longitudinal direction, and the second partitions 12 extend in the transverse direction. The plurality of first partitions 11 and the plurality of second partitions 12 cooperate to form a grid-like structure. The mesh holes of the grid-like structure are arranged in a rectangular shape, and each mesh hole forms a concrete pouring space respectively; the leveling assembly 2 includes a support frame 21 and a plurality of leveling heads 22 that move in the vertical direction. The support frame 21 straddles both sides of the concrete pavement. The plurality of leveling heads 22 are respectively suspended at the bottom of the support frame 21. The plurality of leveling heads 22 are arranged at intervals in the longitudinal direction and are respectively in up-and-down contact with the first partition 11 or the second partition 12. The leveling heads 22 are used to obtain the height information of the first partition 11 or the second partition 12; the elevation assembly 3 includes a plurality of mortar cakes 31 and a plurality of reinforcing members 32 provided in the corresponding mortar cakes 31. The mortar cakes 31 are arranged at intervals on the concrete pavement and are used as a thickness reference for the concrete pavement. The reinforcing members 32 connect the mortar cakes 31 and the ground; each of the plurality of scraping assemblies 4 has a scraper 41. The scraper 41 is slidably arranged on two adjacent second partitions 12 and slides in the transverse direction. The bottom end of the scraper 41 is located on the same horizontal plane as the upper surface of the mortar cake 31.

[0028] It should be noted that the plurality of ash cakes 31 are respectively arranged in corresponding grid holes, or are arranged on both sides of the concrete pavement on the ground, to guide the moving height of the scraper 41 .

[0029] In specific implementation, the leveling heads 22 are in contact with the first baffles 11 respectively, and by measuring the displacement of multiple leveling heads 22, it is determined whether the tops of multiple first baffles 11 are located on the same horizontal plane, so as to ensure that the scraper 41 moves horizontally stably.

[0030] In specific implementation, the leveling heads 22 are in contact with the second partitions 12 respectively, and by measuring the displacement of multiple leveling heads 22, it is determined whether the tops of multiple second partitions 12 are located on the same horizontal plane, thereby ensuring that the bottom edge of the scraper 41 is parallel to the horizontal direction.

[0031] As an embodiment of the reinforcement member 32, the reinforcement member 32 is a reinforcement rib, which is nailed into the corresponding position of the ground before the ash cake 31 is made. When the ash cake 31 is made, the reinforcement member 32 is used as a reference point for casting, thereby improving the casting efficiency of multiple ash cakes 31. A hole can also be opened at the corresponding position of the ground to insert the reinforcement member 32.

[0032] It should be noted that the grid structure formed by the plurality of first baffles 11 arranged at intervals in the transverse direction and the second baffles 12 arranged at intervals in the longitudinal direction can effectively separate and limit the concrete when pouring it. This structure can prevent the concrete from excessively flowing and spreading during the pouring process, so that the concrete can be stably filled in each mesh, reducing the uneven distribution of concrete in different areas of the road surface, thereby improving the overall quality of the concrete road surface. Figure 3 , the solid arrows in the figure represent the horizontal direction, and the dotted arrows represent the vertical direction.

[0033] As an embodiment of the first partition 11 and the plurality of second partitions 12, the plurality of second partitions 12 extend in the transverse direction, the second partition 12 comprises a plurality of I-beams or steel plates connected end to end, the first partition 11 comprises a steel plate, and the first partition 11 is longitudinally arranged on two adjacent second partitions 12. Through holes are provided on the sides of the first partition 11 and the second partition 12 to facilitate the scraper 41 to scrape the concrete slurry.

[0034] Compared with the prior art, the concrete pavement leveling system provided in this embodiment divides a large-area concrete pavement into multiple square small blocks. The reinforcing member 32 in the elevation component 3 connects the plaster cake 31 and the ground to fix the plaster cake 31. The top of the first partition 11 and the second partition 12 are determined to be at the same horizontal plane by the leveling head 22. Finally, the scraper 41 is moved on the second partition 12 to scrape off the excess concrete, so that the concrete pavement within a single grid hole is a flat surface, and the concrete pavement of multiple grid holes is accurately controlled in sequence, improving the flatness and pouring quality of the concrete pavement; the top surface of the plaster cake 31 and the bottom of the scraper 41 are at the same horizontal plane, and the concrete pavement after the scraper 41 scrapes is at the same height as the top of the plaster cake 31, further improving the leveling quality, ensuring that the formed pavement has high flatness and facilitating construction; the plaster cake 31 is connected to the ground through the reinforcing member 32, improving the connection strength with the ground, not falling off during concrete vibration, and improving the stability of construction.

[0035] In some embodiments, referring to Figure 1 and to Figure 3 , the dividing unit 1 further includes a plurality of brackets 13. The brackets 13 are respectively arranged at both ends of the first partition 11 and connected to the first partition 11. The bottom of the brackets 13 is inserted into the concrete pavement. The brackets 13 are inserted into the concrete pavement, the brackets 13 are connected to the first partition 11, and the first partition 11 is connected to the second partition 12. The brackets 13 can support the first partition 11 and the second partition 12, avoiding the contact between the first partition 11 and the second partition 12 and the concrete pavement, and reducing the influence on the concrete pavement; the contact area between the brackets 13 and the concrete pavement is small, and the flatness of the concrete pavement can be minimized.

[0036] During specific implementation, the brackets 13 can lift the first partition 11 and the second partition 12, so that the bottom surface of the second partition 12 is exactly at the same height as the upper surface of the concrete pavement, or only the tops of the first partition 11 and the second partition 12 protrude from the concrete pavement, which can be adjusted according to design requirements specifically.

[0037] In some embodiments, referring to Figure 10 , the bracket 13 includes a plurality of legs 131, a scraping cylinder 132 and a connecting rod 133. The plurality of legs 131 are arranged around the scraping cylinder 132, and the plurality of legs 131 are respectively inserted into the concrete pavement. The scraping cylinder 132 is erected above the concrete pavement. The connecting rod 133 is a screw rod, the connecting rod 133 is screwed inside the scraping cylinder 132, and the bottom of the connecting rod 133 is screwed to the first partition 11 to fix the first partition 11 and control the height of the first partition 11. The legs 131 are steel bars or connecting rods, and the legs 131 are wound around the outer periphery of the scraping cylinder 132 to support the scraping cylinder 132, further reducing the influence on the concrete pavement. The inside of the scraping cylinder 132 is screwed to the connecting rod 133, and the lifting distance of the connecting rod 133 can be stably controlled, and then the heights of the first partition 11 and the second partition 12 can be controlled.

[0038] During specific implementation, a screw connection groove penetrating up and down is provided on the first partition plate 11. The screw connection groove is screwed with the connecting rod 133. By rotating the connecting rod 133, the first partition plate 11 and the connecting rod 133 are in screw rod cooperation, driving the first partition plate 11 to rise and adjust the position. After adjusting the position, it is measured whether it remains horizontal by the leveling head 22.

[0039] In some embodiments, referring to Figure 4 , guide grooves 411 are provided at the bottoms of both ends of the scraping plate 41. The tops of the second partition plates 12 are respectively in sliding fit with the corresponding guide grooves 411. The guide grooves 411 and the tops of the second partition plates 12 are in plug-in sliding fit, so that the scraping plate 41 can move stably, avoiding deviation of the scraping plate 41 during scraping of concrete and affecting the scraping quality.

[0040] In some embodiments, referring to Figures 1 to 4 , the second partition plate 12 has a plurality of connecting holes 121 penetrating up and down. The plurality of connecting holes 121 are arranged horizontally. Mounting holes are provided at both ends of the first partition plate 11 corresponding to the connecting holes 121. The dividing unit 1 further includes a fastener, and the fastener sequentially penetrates through the mounting hole and the corresponding connecting hole 121 from top to bottom. The arrangement of the connecting holes 121 enables the first partition plate 11 to be connected to the second partition plate 12 at different positions of the second partition plate 12, improving the connection flexibility between the first partition plate 11 and the second partition plate 12.

[0041] During specific implementation, the size of a single grid hole can be changed by adjusting the connection position between the first partition plate 11 and the second partition plate 12. When the scraping plate 41 moves on different grid holes, it does not need to be disassembled. The first partition plate 11 is moved horizontally to extend the moving distance of the scraping plate 41 on the second partition plate 12. The scraping plate 41 enters the grid hole where the concrete has not been leveled and scraped. The first partition plate 11 on the grid hole where the scraping has been completed is adjusted in position again, realizing unobstructed movement of the scraping plate 41 along the second partition plate 12. The difficulty of adjusting the position of the first partition plate 11 is less than the difficulty of adjusting the position of the scraping plate 41, which can reduce the number of scraping plates 41 and lower the cost.

[0042] In some embodiments, referring to Figures 1 to 3, the leveling assembly 2 further includes a plurality of lifting driving members 23, a plurality of lifting rods 24, a plurality of displacement sensors 25, and a processor 26. The plurality of lifting driving members 23 are disposed on the top of the support frame 21, and a lifting end that lifts in the vertical direction is formed at the bottom of the lifting driving member 23; the plurality of lifting rods 24 are connected to the bottom of the corresponding lifting end, and the bottom end of the lifting rod 24 is connected to the leveling head 22; the plurality of displacement sensors 25 are respectively disposed on the corresponding leveling heads 22, and an induction surface is provided at the bottom of the displacement sensor 25, and the induction surface can contact the first partition 11 or the second partition 12; the processor 26 is disposed on the top of the support frame 21 and is communicatively connected to the plurality of displacement sensors 25 and the plurality of lifting driving members 23 respectively, and the processor 26 is also communicatively connected to the terminal.

[0043] Specifically, the leveling head 22 is a connector with a clamping protrusion, which facilitates the installation of the displacement sensor 25.

[0044] During specific implementation, the displacement sensor 25 obtains the displacement amount of the lifting rod 24, and judges whether the lifting rod 24 contacts the corresponding first partition 11 or second partition 12 by the extrusion of the induction surface. An inductive displacement sensor can be used, or a capacitive displacement sensor can be used, as long as the displacement amount of the lifting rod 24 can be obtained, which will not be listed one by one here.

[0045] As another implementation manner of the displacement sensor 25, the displacement sensor 25 starts counting when the lifting rod 24 descends, and stops counting when the induction surface contacts the first partition 11 or the second partition 12. By comparing the time consumed by the movement of each lifting rod 24, it is judged whether the first partition 11 and the second partition 12 are inclined or deviated.

[0046] This embodiment provides a specific implementation manner of the leveling assembly 2. The lifting driving member 23 drives the lifting rod 24 to move up and down. The lifting rod 24 moves downward to contact the corresponding first partition 11 or second partition 12. The displacement sensor 25 measures the displacement amount of the lifting rod 24 from the initial position to the contact with the corresponding first partition 11 or second partition 12, and feeds it back to the processor 26. The processor 26 judges whether there is a problem of inclination or inconsistent position height of the first partition 11 or the second partition 12 through data comparison. Thereby, the scraper 41 can stably move horizontally on the second partition 41, ensuring accurate scraping of the concrete and ensuring the consistency of the concrete layer thickness and the flatness of the concrete road surface.

[0047] In some embodiments, refer to Figure 2 and Figure 3, a plurality of lifting drive members 23 are respectively arranged above the intersection points of the grid-like structure; the displacement sensor 25 can obtain the displacement data of the lifting rod 24 and transmit it to the processor 26, and the processor 26 transmits the data to the terminal according to the obtained plurality of displacement data. The lifting drive member 23 is located at the intersection point and can judge whether a single grid is flush with the horizontal plane according to the information transmitted by two adjacent lifting rods 24. The obtained data is reliable, improving the adjustment accuracy.

[0048] In some embodiments, refer to Figure 4 , the scraper assembly 4 further includes a transmission rod 42. One end of the transmission rod 42 is connected to the middle of the scraper 41, and the other end is connected to the power source. The power source drives the transmission rod 42 to move horizontally to drive the scraper 41 to slide horizontally on the second partition 12. The transmission rod 42 is connected to the scraper 41 to connect the scraper 41 with the power source to drive the scraper 41 to move.

[0049] During specific implementation, the scraper 41 can be pulled manually to facilitate precise manual control of the pulling distance; mechanical equipment can also be used. The mechanical equipment is connected to the transmission rod 42 to push the scraper 41 to move. The power source can also be a suspension trolley. The suspension trolley is slidably matched with the support frame 21. A guide rail is arranged at the bottom of the support frame 21, and the suspension trolley moves along the guide rail to drive the transmission rod 42 to move.

[0050] In some embodiments, refer to Figure 1 , moving wheels 27 are arranged at the bottoms of both sides of the support frame 21. The moving wheels 27 roll horizontally to drive the leveling head 22 to move horizontally. The arrangement of the moving wheels 27 enables the support frame 21 to move horizontally, thereby driving the leveling head 22 to move horizontally to measure the positions of the first partition 11 and the second partition 12 at different positions. There is no need to set up the leveling assembly 2 throughout the container yard, improving the flexibility of use. When leveling the concrete in a certain grid hole, the support frame 21 is moved to the corresponding position, increasing the flexibility of use and reducing the use cost.

[0051] In some embodiments, refer to Figure 8 and Figure 9 , the elevation component 3 further includes a construction cylinder 33. The construction cylinder 33 is a conical cylinder. The small end of the construction cylinder 33 is connected to the shaping shell 34. A slurry outlet is formed in the middle of the shaping shell 34. The slurry outlet is communicated with the inside of the construction cylinder 33. A piston plate and a push rod 35 are movably connected to the large end of the construction cylinder 33. The push rod 35 is connected to the piston plate and pushes the piston plate to slide up and down inside the construction cylinder 33. The slurry outlet can be inserted into and out of the reinforcement member 32 up and down.

[0052] This embodiment provides an implementation of the elevation component 3. The construction cylinder 33 can store concrete slurry. By pushing the piston plate with the push rod 35, the piston plate pushes the concrete slurry to enter the shaping shell 34 from the slurry outlet. The shaping shell 34 and the reinforcing member 32 are inserted into each other up and down to determine the production position of the plaster cake 31. Continuously inject concrete slurry into the shaping shell 34 until it is filled. Remove the construction cylinder 33, and the plaster cake 31 remains on the reinforcing member 32. The setting of the construction cylinder 33 can quickly and stably produce the plaster cake 31. The shaping shell 34 can make the outer shapes of multiple plaster cakes 31 the same, ensure the leveling effect of the plaster cake 31, and improve the reliability of the construction.

[0053] Based on the same inventive concept, referring to Figures 5 to 7 , this application also provides a construction method for leveling a concrete road surface. The method includes the following steps: S1: Install the reinforcing member 32 at a preset position and make the plaster cake 31 on the outer periphery of the reinforcing member 32; S2: Set up the first partition 11 and the second partition 12 on the concrete road surface to form a grid-like structure and pour concrete slurry; S3: Wait for the concrete to be vibrated. After the vibration is completed, determine the levelness of the first partition 11 and the second partition 12 through the leveling head 22, place the scraper 41 and make the scraper 41 level with the upper surface of the plaster cake 31; S4: Drive the scraper 41 to move along the second partition 12 to scrape off the excess concrete slurry and make the thickness of the concrete road surface uniform.

[0054] For the construction method for leveling a concrete road surface provided in this embodiment, compared with the prior art, the reinforcing member 32 provides additional support and anchoring effects for the plaster cake 31, preventing the plaster cake 31 from shifting or deforming due to external forces (such as personnel walking, vibration of construction equipment, etc.) during subsequent construction. The grid-like structure divides the concrete road surface into multiple small units, and the concrete slurry fills in each mesh hole, avoiding the disorderly flow and diffusion of the concrete, which is beneficial to controlling the distribution range of the concrete. Driving the scraper to move along the second partition to scrape off the excess concrete slurry can effectively make the thickness of the concrete road surface uniform. The scraper moves along the partition and takes the height marked by the plaster cake as the reference, and can scrape off the concrete that exceeds the designed thickness, ensuring the uniform thickness of the entire road surface in the transverse direction, improving the quality of the concrete road surface, reducing the unevenness on the surface, and providing a good foundation for subsequent road surface treatment (such as plastering, etc.).

[0055] During specific implementation, referring to the figure, the relative positions of two adjacent first partitions 11 in the horizontal direction can be adjusted, thereby changing the size of a single grid hole. When the scraping plate 41 moves on different grid holes, it does not need to be disassembled. Move the first partition 11 in the horizontal direction to extend the moving distance of the scraping plate 41 on the second partition 12. The scraping plate 41 enters the grid hole where the concrete has not been leveled and scraped. The position of the first partition 11 on the grid hole that has been scraped is adjusted again to achieve unobstructed movement of the scraping plate 41 along the second partition 12. The difficulty of adjusting the position of the first partition 11 is less than that of adjusting the position of the scraping plate 41, which can reduce the number of scraping plates 41 and lower the cost.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
