Description

Technical Field

[0001] This application relates to the technical field of pavement engineering, and more specifically, to a leveling device and construction method for paving the edge of an invisible drainage ditch in a square. Background Art

[0002] In the paving projects of public areas such as squares and pedestrian streets, invisible drainage ditches are widely used as drainage structures. However, the leveling process of the paving at the edge of the drainage ditch has always been a construction difficulty, directly affecting the drainage efficiency, paving aesthetics and service durability. At present, most of the existing leveling devices for the edge of the drainage ditch adopt an embedded structure, and the height of the paving layer is adjusted by means of temporary supports or fixing parts. However, its design defects lead to problems such as high construction costs and single functions, which are specifically manifested in the following two aspects: 1. In the prior art, leveling devices (such as plastic buckles, metal brackets, screw studs, etc.) are directly embedded in the cement mortar layer during the paving process of the edge of the drainage ditch. One leveling device is consumed for each floor tile laid, and the device cannot be recycled after being solidified by the mortar, resulting in a large amount of material consumption. In large-scale paving scenarios, the number of leveling devices and the number of floor tiles show a linear growth relationship, significantly increasing the material procurement and construction costs. Moreover, during the construction, it is necessary to frequently manually position and adjust the components in the leveling device, reducing the paving efficiency.

[0003] 2. The lack of functional integration and collaborative design. The existing leveling devices for paving the edge of the invisible drainage ditch in a square often only focus on height adjustment, while ignoring the composite functional requirements of coordinating and assisting the paving operation at the edge of the drainage ditch. Summary of the Invention

The output port of one of the two electric control grouting pumps is connected to the grouting hole of the grouting cavity forming member in one paving auxiliary module through a first telescopic hose, and the output port of the other electric control grouting pump of the two electric control grouting pumps is connected to the grouting hole of the grouting cavity forming member in the other paving auxiliary module through a second telescopic hose. The first telescopic hose and the second telescopic hose respectively pass through the grouting pipe through holes on the corresponding leveling adapter plates.

[0014] In addition, the present invention also provides a construction method for the concealed drainage ditch edge paving in the square. Among them, the construction method for the concealed drainage ditch edge paving in the square is implemented by using the above-mentioned leveling device for the concealed drainage ditch edge paving in the square. The construction method for the concealed drainage ditch edge paving in the square includes the steps of: a. Construct concrete blocks on both inner sides of the drainage ditch so that the dimensions of each concrete block in the width direction of the drainage ditch are respectively equal to the widths of the grouting cavity upper plates in the two paving auxiliary modules, and the upper surfaces of the concrete blocks are lower than the ground on both sides of the drainage ditch; b. Adjust the lifting of the grouting cavity forming member in each paving auxiliary module relative to the corresponding leveling and anchoring member so that the distance between the leveling adapter plate and the corresponding grouting cavity upper plate is equal to or less than the thickness of the cover body for paving and covering the drainage ditch, and then lock the grouting cavity forming member to the corresponding leveling and anchoring member.

[0015] The beneficial effects of the square invisible drainage ditch edge paving leveling device provided by the present invention are: Compared with the prior art, the 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 is provided with a leveling anchor and a grouting cavity forming member, the leveling anchor includes a leveling adapter plate for supporting on the ground on one side of the drainage ditch, and the grouting cavity forming member includes a grouting cavity upper plate parallel to the leveling adapter plate. Therefore, when the invisible drainage ditch edge paving leveling device is applied to the invisible drainage ditch edge paving operation in the square, the corresponding leveling adapter plates of the two paving auxiliary modules can be respectively supported and pressed against the ground on both sides of the drainage ditch. At this time, the grouting cavity upper plate of the grouting cavity forming member is parallel to the ground on both sides of the drainage ditch, thereby realizing the leveling operation in the process of paving the invisible drainage ditch edge of the square without the aid of instruments such as a spirit level. The leveling operation refers to the filling of a cement mortar layer in the grouting cavity. The upper surface of the cement mortar layer is parallel to the ground on both sides of the drainage ditch, thereby ensuring the flatness of the cover (such as bricks) for sealing the drainage ditch laid on the upper surface of the cement mortar layer, and the two paving auxiliary modules can be lifted and separated from the cement mortar layer after the cement mortar is filled. No components are embedded in the cement mortar layer during the entire leveling and grouting process, and leveling can be performed without consuming the 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 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 to form a grouting cavity, which not only has the leveling function, but also has the grouting auxiliary function.

[0023] See Figures 1 to 7 , the present invention provides a leveling device for paving beside an invisible drainage ditch in a square. Among them, the leveling device for paving beside an invisible drainage ditch in a square includes: A bracket 100, including a bracket main body 101 and a first upright 102 and a second upright 103 respectively connected to the lower sides of both sides of the bracket main body 101. The first upright 102 and the second upright 103 can support on both sides of the drainage ditch 15 so that the bracket main body 101 straddles above the drainage ditch 15. Travel wheels 5 can be arranged below each of the first upright 102 and the second upright 103; An electric control lifting mechanism, which is connected to the bracket main body 101; 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 control lifting mechanism through an angle conversion structure, the grouting cavity forming member 400 is liftably and lockably connected 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, and 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 respectively.

[0024] Since the 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 invisible drainage ditch edge paving leveling device is used in the invisible drainage ditch edge paving operation of the square, the corresponding leveling adapter plates 301 of the two paving auxiliary modules can be supported and pressed against 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 in the process of paving the invisible drainage ditch edge of the square can be realized without the aid 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) for covering the drainage ditch 15 laid on the upper surface of the cement mortar layer 17, and the two paving auxiliary modules can be lifted and separated from the cement mortar layer 17 after the cement mortar is filled. During the entire leveling and grouting process, no components are embedded in the cement mortar layer 17, and leveling can be performed without consuming the leveling device, which greatly saves the consumption of parts in the process of paving the edge of the square invisible drainage ditch. Moreover, the grouting cavity forming member 400 in the leveling device for paving the edge of the square invisible drainage ditch 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 of the leveling device for paving the edge of the square invisible drainage ditch and the ability of diversified collaborative auxiliary drainage ditch 15 edge paving operations.

[0025] According to an embodiment of the present application, the leveling device for paving at the edge of the square invisible drainage ditch 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 with a sliding plate 2 and can drive the sliding plate 2 to move along the first linear electric guide rail 1. The electric control lifting mechanism includes four cylinders 4 connected to the lower part of the sliding plate 2. The angle transformation structure includes four universal joints 200 arranged at equal angles in the horizontal plane. The lower ends of the four cylinders 4 are respectively 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 directly above the drainage ditch 15, which is convenient for subsequent lowering to implement various auxiliary functions for paving at the edge of the drainage ditch. Specifically, two of the four cylinders 4 are arranged in a first straight line in the horizontal direction, and the other two cylinders 4 are arranged in a second straight line in the horizontal direction. The first straight line is perpendicular to the second straight line. Specifically, during the paving process at the edge of the square invisible drainage ditch, the first straight line can extend along the length direction of the drainage ditch 15, and the second straight line can extend along the width direction of the drainage ditch 15. The telescopic operation of the piston rods of the four cylinders 4, combined with the angle adjustment function of the universal joints 200, further improves the fitting degree of the corresponding leveling and adapting plates 301 of the two paving auxiliary modules to respectively support and lean against the ground on both sides of the drainage ditch 15.

[0026] According to an embodiment of the present application, the upper parts of the two paving auxiliary modules are connected to the universal joints 200 through a support plate 6. Preferably, the upper part of the support plate 6 is connected to the universal joints 200 through an electric control rotary table 14, and the rotation axis of the electric control rotary table 14 is perpendicular to the support plate 6.

[0027] Specifically, the universal joint 200 includes a universal ball sleeve 202 and a universal ball body 201 movably clamped in the universal ball sleeve 202. The universal ball body 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 rotary table 14.

[0028] According to an embodiment of the present application, a second linear electric guide rail 7 and a third linear electric guide rail 8 are connected below 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 both extend along the arrangement direction of the first upright frame 102 and the second upright frame 103. One leveling and anchoring member 300 of the two paving auxiliary modules is slidably connected to the second linear electric guide rail 7, and the other leveling and anchoring member 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 from or close to each other through 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 with 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 both the second linear electric guide rail 7 and the third linear electric guide rail 8 can also be provided below the support plate 6. The leveling and anchoring members 300 of the two paving auxiliary modules are also slidably engaged with the slide rail 9 through guide blocks 10 having chutes.

[0029] According to a specific embodiment of the present application, the leveling and anchoring member 300 further includes a connecting plate 302 extending vertically downward from the leveling adapter plate 301. The grouting cavity forming member 400 includes a first grouting cavity vertical plate 402 extending vertically downward from the grouting cavity upper plate 401. The first grouting cavity vertical plate 402 is connected to the connecting plate 302 in a liftable and lockable manner. The two leveling adapter plates 301 of the two paving auxiliary modules extend in opposite directions from the corresponding connecting plates 302, and the two grouting cavity upper plates 401 of the two paving auxiliary modules extend in opposite directions from the corresponding first grouting cavity vertical plates 402.

[0030] In addition, a vertical slide rail 11 is provided on the connecting plate 302. The first grouting cavity 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. The first grouting cavity vertical plate 402 can be locked to the connecting plate 302 by a locking screw 12 passing through the threaded through hole and abutting against the first grouting cavity vertical plate 402.

[0031] According to an 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 in pairs, and the second grouting cavity vertical plate 403 is connected to the end faces of the grouting cavity upper plate 401 and the first grouting cavity vertical plate 402 in their respective length directions. According to the construction method described later, it can be known that by making the lower side faces of the first grouting cavity vertical plates 402 in the respective grouting cavity forming members 400 of the two paving auxiliary modules abut against the corresponding concrete blocks 16, the inner side wall of the drainage ditch 15, the upper surface of the corresponding concrete block 16, and the corresponding grouting cavity forming member 400 can enclose a grouting cavity. The grouting cavity is a rectangular space. The grouting cavity forming member 400 specifically encloses three faces of the rectangular space by the grouting cavity upper plate 401, the first grouting cavity vertical plate 402, and the second grouting cavity vertical plate 403 that are perpendicular to each other in pairs. The inner side wall in the width direction of the drainage ditch 15 and the upper surface of the corresponding concrete block 16 together enclose two faces of the rectangular space. If the paving construction is carried out from the starting end or the ending end of the length direction of the drainage ditch 15, the last face (the face parallel and opposite to the second grouting cavity vertical plate 403) of the rectangular space can be enclosed by the inner side wall in the length direction of the drainage ditch 15. When sequentially enclosing the grouting cavity later, the last face of the rectangular space can be enclosed by the end face in the length direction of the previously formed cement mortar layer 17 along the drainage ditch 15. If the paving construction is carried out from any middle section of the length direction of the drainage ditch 15, since the last face (the face parallel and opposite to the second grouting cavity vertical plate 403) of the rectangular space cannot be enclosed by the inner side wall in the length direction of the drainage ditch 15, a third grouting cavity vertical plate having the same size as the second grouting cavity vertical plate 403 can be detachably connected to the other end faces of the grouting cavity upper plate 401 and the first grouting cavity vertical plate 402 in their respective length directions. The third grouting cavity vertical plate is parallel and opposite to the second grouting cavity vertical plate, so as to enclose the last face of the rectangular space. The structure for enclosing the other faces of the rectangular space remains unchanged. When sequentially enclosing the grouting cavity later, the third grouting cavity vertical plate can be removed, and the last face of the rectangular space can be enclosed by the end face in the length direction of the previously formed cement mortar layer 17 along the drainage ditch 15.

[0032] According to an embodiment of the present application, the leveling device for paving beside the invisible drainage ditch in the square includes two electric control grouting pumps 3 connected to the sliding plate 2. The output port of one of the two electric control grouting pumps 3 is connected to the grouting hole 404 of the grouting cavity forming member 400 in one paving auxiliary module through a first telescopic hose (not shown). The output port of the other electric control grouting pump 3 among the two electric control grouting pumps 3 is connected to the grouting hole 404 of the grouting cavity forming member 400 in the other 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 plates 301. 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.

[0033] In addition, the present invention also provides a construction method for paving beside the invisible drainage ditch in the square. Among them, the construction method for paving beside the invisible drainage ditch in the square is implemented by using the above-mentioned leveling device for paving beside the invisible drainage ditch in the square. The construction method for paving beside the invisible drainage ditch in the square includes the following steps: a. Build concrete blocks 16 on both inner sides of the drainage ditch 15, so that the dimensions of each concrete block 16 in the width direction of the drainage ditch 15 are respectively equal to the widths of the upper plates 401 of the grouting cavities in the two paving auxiliary modules, and make the upper surfaces of the concrete blocks 16 lower than the ground on both sides of the drainage ditch 15. In fact, the space from above the upper surfaces of the concrete blocks 16 to below the ground on both sides of the drainage ditch 15 needs to reserve the required layout height of the subsequent mentioned cement mortar layer 17 and the cover body 18. b. Adjust the lifting of the grouting cavity forming member 400 in each paving auxiliary module relative to the corresponding leveling anchoring member 300, so that the distance between the leveling adapter plate 301 and the corresponding upper plate 401 of the grouting cavity is equal to or less than the thickness of the cover body 18 for paving and covering the drainage ditch 15, and then lock the grouting cavity forming member 400 to the corresponding leveling anchoring member 300. The cover body 18 has vertical drainage through holes. The cover body 18 can be a brick, a tile, a stone slab or a metal plate, etc. A rain grate 19 can be installed in the vertical drainage through holes. c. Support the first vertical frame 102 and the second vertical frame 103 on both sides of the drainage ditch 15 so that the bracket main body 101 straddles above the drainage ditch 15. d. Adjust the actions of the electric 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 inside of the drainage ditch 15 until the corresponding leveling and adapting plates 301 of the two paving auxiliary modules respectively support and lean against the ground on both sides of the drainage ditch 15, and the end in the width direction of the grouting chamber upper plate 401 in the grouting chamber forming member 400 of each of the two paving auxiliary modules leans against the corresponding inner side wall of the drainage ditch 15, and the lower side surface of the first grouting chamber vertical plate 402 in the grouting chamber forming member 400 of each of the two paving auxiliary modules leans against the corresponding concrete block 16, so that the inner side wall of the drainage ditch 15, the upper surface of the corresponding concrete block 16, and the corresponding grouting chamber forming member 400 enclose a grouting chamber; e. Start the two electric grouting pumps 3 to fill the two grouting chambers corresponding to the two paving auxiliary modules with cement mortar to respectively form cement mortar layers 17 on the concrete blocks 16 on both sides inside the drainage ditch 15; f.
