Description

Technical Field

[0001] The present application relates to the field of pavement engineering technology, and more specifically, to a square invisible drainage ditch edge paving leveling device and a construction method. Background Art

[0002] Invisible drains are widely used as drainage structures in paving projects in public areas such as squares and pedestrian streets. However, the leveling process for the ditch edge pavement has always been a construction difficulty, directly affecting drainage efficiency, pavement aesthetics, and durability. Currently, existing ditch edge leveling devices mostly use pre-buried structures, using temporary supports or fixings to assist in adjusting the pavement layer height. However, these design flaws lead to high construction costs and limited functionality, which are specifically manifested in the following two aspects:

[0003] 1. In the existing technology, leveling devices (such as plastic clips, metal brackets, screws and studs, etc.) are directly embedded in the cement mortar layer during the paving process beside the drainage ditch. Each leveling device is consumed for each floor tile laid, and the device cannot be recycled after the mortar is cured, resulting in a large amount of material consumption. In large-scale paving scenarios, the number of leveling devices increases linearly with the number of floor tiles, significantly increasing material procurement and construction costs. In addition, frequent manual positioning and adjustment of components in the leveling device are required during construction, reducing paving efficiency.

[0004] 2. Insufficient functional integration and lack of collaborative design. The existing invisible drainage ditch edge paving leveling device in the square often only focuses on height adjustment, while ignoring the complex functional requirements of coordination and auxiliary drainage ditch edge paving operations.

[0041] See also Figures 1 to 7 The present invention provides a leveling device for paving the edge of an invisible drainage ditch in a square, wherein the leveling device for paving the edge of an invisible drainage ditch in a square comprises:

[0042] The bracket 100 includes a bracket body 101 and a first upright frame 102 and a second upright frame 103 respectively connected to the lower sides of the bracket body 101. The first upright frame 102 and the second upright frame 103 can be supported on both sides of the drainage ditch 15 so that the bracket body 101 spans above the drainage ditch 15. The first upright frame 102 and the second upright frame 103 can be provided with walking wheels 5 below each of the first upright frame 102 and the second upright frame 103.

[0043] An electrically controlled lifting mechanism connected to the support body 101;

[0044] Two paving auxiliary modules, the paving auxiliary modules include a leveling anchor 300 and a grouting cavity forming member 400. The leveling anchor 300 is connected to the bottom of the electric lifting mechanism through an angle conversion structure. The grouting cavity forming member 400 is liftable and lockable to the leveling anchor 300. The leveling anchor 300 includes a leveling adapter plate 301 for supporting on the ground on one side of the drainage ditch 15. The grouting cavity forming member 400 includes a grouting cavity upper plate 401 parallel to the leveling adapter plate 301. A grouting pipe through hole 303 is formed on the leveling adapter plate 301. A grouting hole 404 is formed on the grouting cavity upper plate 401. The grouting cavity forming member 400 can be combined with the inner wall of the drainage ditch 15 to form a grouting cavity. The angle conversion structure can improve the fit of the corresponding leveling adapter plates 301 of the two paving auxiliary modules to the ground on both sides of the drainage ditch 15.

[0045] Since the square invisible drainage ditch edge paving leveling device provided by the present invention has an electric-controlled lifting mechanism and two paving auxiliary modules, and the paving auxiliary module has a leveling anchor 300 and a grouting cavity forming member 400, the leveling anchor 300 includes a leveling adapter plate 301 for supporting on the ground on one side of the drainage ditch 15, and the grouting cavity forming member 400 includes a grouting cavity upper plate 401 parallel to the leveling adapter plate 301. Therefore, when the square invisible drainage ditch edge paving leveling device is used in the square invisible drainage ditch edge paving operation, the corresponding leveling adapter plates 301 of the two paving auxiliary modules can be supported and attached to the ground on both sides of the drainage ditch 15 respectively. At this time, the grouting cavity upper plate 401 of the grouting cavity forming member 400 is parallel to the ground on both sides of the drainage ditch 15, so that the leveling operation during the square invisible drainage ditch edge paving process can be achieved without the help of instruments such as a spirit level. The leveling operation refers to filling the cement mortar layer 17 in the grouting cavity. The upper surface of the cement mortar layer 17 is parallel to the ground on both sides of the drainage ditch 15, thereby ensuring the flatness of the cover 18 (such as bricks) laid on the upper surface of the cement mortar layer 17 for covering the drainage ditch 15, and after the cement mortar is filled, the two paving auxiliary modules can be lifted up and separated from the cement mortar layer 17. No components are embedded in the cement mortar layer 17 during the entire leveling and grouting process, and leveling can be performed without consuming a leveling device, which greatly saves the consumption of parts in the process of paving the edge of the invisible drainage ditch of the square. Moreover, the grouting cavity forming member 400 in the leveling device for paving the edge of the invisible drainage ditch of the square can be combined with the inner wall of the drainage ditch 15 to form a grouting cavity, which not only has a leveling function, but also has a grouting auxiliary function. There is no need to use additional enclosures to form a grouting cavity, which greatly expands the functional integration and diversified collaborative auxiliary drainage ditch 15 edge paving operation of the invisible drainage ditch of the square.

[0046] According to one embodiment of the present application, a leveling device for paving the edge of an invisible drainage ditch in a square includes a first linear electric guide rail 1, which extends along the arrangement direction of the first vertical frame 102 and the second vertical frame 103. The first linear electric guide rail 1 is connected to a sliding plate 2 and can drive the sliding plate 2 to move along the first linear electric guide rail 1. The electric lifting mechanism includes four cylinders 4 connected to the bottom of the sliding plate 2. The angle conversion structure includes four universal joints 200 arranged at equal angles in a horizontal plane. The lower ends of the four cylinders 4 are connected to the universal joints 200 one by one. The upper part of the paving auxiliary module is connected to the universal joints 200. The first linear electric guide rail 1 can drive the paving auxiliary module to be in the drainage ditch 15. The position directly above is convenient for subsequent descent to implement various auxiliary functions of paving the edge of the drainage ditch. Specifically, two of the four cylinders 4 are arranged along a first straight line in the horizontal direction, and the other two cylinders 4 are arranged along a second straight line in the horizontal direction. The first straight line is perpendicular to the second straight line. Specifically, in the process of paving the edge of the invisible drainage ditch in the square, the first straight line can be extended along the length direction of the drainage ditch 15, and the second straight line can be extended along the width direction of the drainage ditch 15. The telescopic operation of the various piston rods of the four cylinders 4 is combined with the angle adjustment function of each universal joint 200, which further improves the fit of the corresponding leveling adapter plates 301 of the two paving auxiliary modules to the ground on both sides of the drainage ditch 15.

[0047] According to one embodiment of the present application, the two paving auxiliary modules are connected to the universal joints 200 via a support plate 6. Preferably, the support plate 6 is connected to the universal joints 200 via an electric turntable 14, and the rotation axis of the electric turntable 14 is perpendicular to the support plate 6.

[0048] Specifically, the universal joint 200 includes a universal ball sleeve 202 and a universal ball 201 movably mounted in the universal ball sleeve 202 . The universal ball 201 is connected to the end of the piston rod of the cylinder 4 , and the lower end of the universal ball sleeve 202 is connected to the upper surface of the electric control turntable 14 .

[0049] According to one embodiment of the present application, a second linear electric guide rail 7 and a third linear electric guide rail 8 are connected to the bottom of the support plate 6. The second linear electric guide rail 7 and the third linear electric guide rail 8 are parallel to each other and extend along the arrangement direction of the first upright frame 102 and the second upright frame 103. One leveling anchor 300 in the two paving auxiliary modules is slidably connected to the second linear electric guide rail 7, and the other leveling anchor 300 is slidably connected to the third linear electric guide rail 8. The advantage of this embodiment is that the two paving auxiliary modules can be controlled to move away or closer by the second linear electric guide rail 7 and the third linear electric guide rail 8, so that the two paving auxiliary modules can adapt to the paving operations of drainage ditches 15 of different widths. In order to improve the stability of the slidable connection between the two paving auxiliary modules and the support plate 6, a slide rail 9 parallel to the second linear electric guide rail 7 and the third linear electric guide rail 8 can also be provided under the support plate 6. The leveling anchor 300 of each of the two paving auxiliary modules is also slidably matched with the slide rail 9 through a guide block 10 with a slide groove.

[0050] According to a specific embodiment of the present application, the leveling anchor 300 also includes a connecting plate 302 extending vertically downward from the leveling adapter plate 301, and the grouting chamber forming member 400 includes a first grouting chamber vertical plate 402 extending vertically downward from the grouting chamber upper plate 401. The first grouting chamber vertical plate 402 is connected to the connecting plate 302 in a liftable and lockable manner. The two leveling adapter plates 301 in the two paving auxiliary modules extend in opposite directions from the corresponding connecting plates 302, and the two grouting chamber upper plates 401 in the two paving auxiliary modules extend in opposite directions from the corresponding first grouting chamber vertical plate 402.

[0051] In addition, a vertical slide rail 11 is provided on the connecting plate 302, and the first grouting chamber vertical plate 402 is slidably connected to the vertical slide rail 11 through a slider 13. A threaded through hole is provided on the connecting plate 302, and the first grouting chamber vertical plate 402 can be locked to the connecting plate 302 by a locking screw 12 that passes through the threaded through hole and abuts against the first grouting chamber vertical plate 402.

[0052] According to one embodiment of the present application, the grouting cavity forming member 400 further includes a second grouting cavity vertical plate 403 extending vertically downward from the grouting cavity upper plate 401, the grouting cavity upper plate 401, the first grouting cavity vertical plate 402 and the second grouting cavity vertical plate 403 are perpendicular to each other, and the second grouting cavity vertical plate 403 is connected to the end faces of the length direction of the grouting cavity upper plate 401 and the first grouting cavity vertical plate 402 respectively. According to the construction method recorded later, it can be known that the lower end side surfaces of the first grouting cavity vertical plate 402 in the grouting cavity forming members 400 of the two paving auxiliary modules are abutted against the corresponding The concrete blocks 16 can make the inner side wall of the drainage ditch 15, the upper surface of the corresponding concrete blocks 16 and the corresponding grouting cavity forming member 400 enclose a grouting cavity. The grouting cavity is a rectangular space. The grouting cavity forming member 400 specifically blocks three sides of the rectangular space through two vertical grouting cavity upper plates 401, the first grouting cavity vertical plates 402 and the second grouting cavity vertical plates 403. The inner side wall in the width direction of the drainage ditch 15 and the upper surface of the corresponding concrete blocks 16 enclose two sides of the rectangular space. If the drainage ditch 15 is started from the starting end or the end in the length direction, the grouting cavity is enclosed. During paving construction, the last face of the rectangular space (the face parallel to and opposite to the second grouting chamber vertical plate 403) can be enclosed by the inner side wall of the length direction of the drainage ditch 15. When the grouting chambers are subsequently enclosed, the last face of the rectangular space can be enclosed along the end face of the length direction of the drainage ditch 15 by the previously formed cement mortar layer 17. If paving construction is carried out from any middle section in the length direction of the drainage ditch 15, since the last face of the rectangular space (the face parallel to and opposite to the second grouting chamber vertical plate 403) cannot be enclosed by the inner side wall of the length direction of the drainage ditch 15 A third grouting chamber vertical plate with the same size as the second grouting chamber vertical plate 403 can be detachably connected to the other end face of the grouting chamber upper plate 401 and the first grouting chamber vertical plate 402 in the length direction. The third grouting chamber vertical plate is parallel to the second grouting chamber vertical plate 403, so that the last face of the rectangular space can be enclosed. The structure of the other faces of the enclosed rectangular space remains unchanged. When the grouting chambers are enclosed in sequence later, the third grouting chamber vertical plate is removed, and the last face of the rectangular space can be enclosed along the end face in the length direction of the drainage ditch 15 by the previously formed cement mortar layer 17.

[0053] According to one embodiment of the present application, a paving leveling device for the invisible drainage ditch edge of a square includes two electrically controlled grouting pumps 3 connected to a sliding plate 2, the output port of one electrically controlled grouting pump 3 of the two electrically controlled grouting pumps 3 is connected to a grouting hole 404 of a grouting cavity forming member 400 in a paving auxiliary module through a first telescopic hose (not shown), and the output port of the other electrically controlled grouting pump 3 of the two electrically controlled grouting pumps 3 is connected to a grouting hole 404 of a grouting cavity forming member 400 in another paving auxiliary module through a second telescopic hose (not shown), the first telescopic hose and the second telescopic hose respectively pass through the grouting pipe through holes 303 on the corresponding leveling adapter plate 301, and the support plate 6 can be provided with two long holes 61 for the first telescopic hose and the second telescopic hose to pass through respectively.

[0054] In addition, the present invention also provides a construction method for paving the edge of an invisible drainage ditch in a square, wherein the construction method for paving the edge of an invisible drainage ditch in a square is implemented by using the above-mentioned invisible drainage ditch edge paving leveling device for the square, and the construction method for paving the edge of an invisible drainage ditch in a square comprises the following steps:

Concrete blocks 16 are laid on both sides of the drainage ditch 15, with the width of each concrete block 16 in the drainage ditch 15 being equal to the width of the upper grouting cavity plates 401 in the two auxiliary paving modules. The upper surface of the concrete blocks 16 is lower than the ground on both sides of the drainage ditch 15. In fact, the space between the upper surface of the concrete blocks 16 and the ground on both sides of the drainage ditch 15 needs to reserve the required height for the cement mortar layer 17 and the cover 18 mentioned later.

[0056] b. Adjust the grouting cavity forming member 400 in each paving auxiliary module relative to the corresponding leveling anchor 300 so that the distance between the leveling adapter plate 301 and the corresponding grouting cavity upper plate 401 is equal to or less than the thickness of the cover 18 of the drainage ditch 15 to be paved and covered. Then lock the grouting cavity forming member 400 to the corresponding leveling anchor 300. The cover 18 has vertical drainage holes. The cover 18 can be made of bricks, tiles, stone slabs or metal plates. Rainwater grates 19 can be installed in the vertical drainage holes.

[0057] c. Support the first stand 102 and the second stand 103 on both sides of the gutter 15 so that the bracket body 101 spans over the gutter 15;

[0058] d. Adjust the electric-controlled lifting mechanism, the first linear electric guide rail 1, the second linear electric guide rail 7, and the third linear electric guide rail 8 so that each paving auxiliary module moves downward into the interior of the drainage ditch 15 until the corresponding leveling adapter plates 301 of the two paving auxiliary modules are respectively supported and abutted against the ground on both sides of the drainage ditch 15, and the ends in the width direction of the grouting cavity upper plates 401 in the grouting cavity forming members 400 of the two paving auxiliary modules are abutted against the corresponding inner side walls of the drainage ditch 15, and the lower end sides of the first grouting cavity vertical plates 402 in the grouting cavity forming members 400 of the two paving auxiliary modules are abutted against the corresponding concrete blocks 16, so that the inner side walls of the drainage ditch 15, the upper surfaces of the corresponding concrete blocks 16, and the corresponding grouting cavity forming members 400 are combined to form a grouting cavity;

[0059] e. Start the two electrically controlled grouting pumps 3 to fill the two grouting cavities corresponding to the two paving auxiliary modules with cement mortar to form cement mortar layers 17 on the concrete blocks 16 on both sides of the interior of the drainage ditch 15;

[0060] f. After the cement mortar layer 17 is dry, the cover 18 is laid on the corresponding cement mortar layers 17 on both sides of the interior of the drainage ditch 15 so that the cover 18 covers the upper end of the drainage ditch 15 .
