Description

Technical Field

[0001] The invention relates to a granite curbstone paving vehicle and a paving method thereof, belonging to the technical field of municipal engineering road construction equipment and construction methods. Background Art

[0002] With the progress of society and the development of urban roads, people's requirements for the practicality, safety and aesthetics of municipal roads are constantly increasing. Correspondingly, the requirements for the curbstones on both sides of the road are also getting higher and higher.

[0003] Curbstone is also called curbstone, and its English name is Curb. It refers to the boundary stone set at the edge of the road surface. It is abbreviated as curbstone, commonly known as curb. It is a stone strip set at the edge of the road surface to separate it from other structural zones.

[0004] Curbstones are classified according to their materials into cement concrete curbstones and natural stone curbstones. Among natural stone curbstones, granite curbstones are the best. Regardless of practicality, appearance and durability, granite curbstones are superior to curbstones made of other natural stones, and even better than prefabricated cement concrete curbstones. Therefore, granite curbstones are now widely used.

[0005] Because granite is hard, dense and has a high specific gravity, curbstones of the same specifications and volume are much heavier than curbstones made of other natural stones and curbstones made of cement concrete. Therefore, it is much more difficult to transport and pave granite curbstones than curbstones made of other natural stones and curbstones made of cement concrete.

[0006] The paving of curbstones mainly includes surveying and setting out, nailing and wiring, mortar cushion, paving and laying of curbstones, filling and compacting the bottom of curbstones, and joint maintenance, among which:

[0007] The measurement and setting out steps are to place nails and columns according to the designed edge line after the construction of the cement stabilized gravel layer is completed, and the curb line and construction elevation are measured to control the direction and elevation of the curb line;

[0008] The steps of stake laying are to open the foundation groove of the curbstone after setting out, and stake and hang the line. The straight section can be laid out with a rope, and the curved section can be marked with lime powder. Then the elevation of the top surface of the curbstone is measured and a mark is placed.

[0009] The mortar cushioning step is to lay 2 cm of cement mortar as a cushioning layer after the foundation is made in the foundation trench;

[0010] The steps of kerbstone transportation and paving are to transport the kerbstones from the yard to the construction site and put them into the kerbstone foundation groove with cement mortar cushion layer, arrange them along the gray line, and then carefully adjust the arrangement position of the kerbstones and adjust the height difference. The lower end of the kerbstone needs to be lifted with a lifting tool, and then padded with concrete or mortar underneath to make the height of the kerbstone reach the design standard; the higher end is padded with a wooden board on its top surface and tamped with a rubber hammer to make it sink to the allowable error.

[0011] The steps of filling and compacting the bottom of the curbstone are as follows: after the curbstone is paved and laid, the inner side of the bottom of the curbstone is filled with fine stone concrete, and the outer side is compacted with lime soil or fill soil. The tamping width is not less than 44cm, the height is not less than 15cm, and the density should reach more than 90%. If the curbstone is found to be tilted or moved during filling, it needs to be reworked and repaired;

[0012] The grouting maintenance procedure is to use cement slurry with a strength of 10Mpa to evenly embed the joints of the curbstones after the pavement is paved, complete the grouting, and then perform maintenance until the grouting cement slurry reaches the specified strength.

[0013] The paving of curbstones should be:

[0014] The straight part is neat and straight, the curved part is round and beautiful without any corners; the joints are full, neat and solid, and the maintenance is not less than three days; the allowable deviation of the seam width is ±3 mm; the maximum deviation of straightness checked with a 20-meter straight line is no more than 10 mm; the density of the soil fill at the bottom of the trench should reach more than 90%.

[0015] From the above-mentioned paving technology and paving quality standards of curbstones, it can be seen that:

[0016] The transportation, paving and laying of curbstones is not only a laying technical step, but also a key and controlling step of curbstone paving, which is related to the construction period and quality of the entire curbstone paving. At the same time, it is a heavy and even dangerous physical operation step, because curbstones are usually huge and heavy. Therefore, strong physical strength is required when transporting and laying them. In addition, the straight part of the curbstone paving and laying is required to be neat and straight, and the curved part is required to be round and beautiful without corners. Therefore, when paving and laying curbstones, it is often necessary to adjust the position and height, which requires lifting and moving the curbstones many times, which is extremely time-consuming and labor-intensive, and also greatly consumes the physical strength of the construction workers and may cause injuries.

[0017] In the prior art, there is no special mechanical equipment for the transportation, paving and masonry of curbstones. Although there are some simple transportation tools, such as the "Simple Curbstone Installation and Transfer Vehicle" provided by the utility model patent (application number 201720514448.2), which solves some problems of curbstone installation and transportation, the curbstone lifting method is inconvenient to operate, and the direction and angle of the curbstone after lifting cannot be adjusted. Therefore, the current curbstone transportation, paving and masonry construction still mainly relies on manual work.

[0018] Manually transporting, paving and laying kerbstones is time-consuming, laborious and has potential safety risks, especially for the paving of heavier kerbstones such as granite kerbstones, which is even more difficult and dangerous. Summary of the invention

[0019] In order to overcome the shortcomings of the existing related technologies, the present invention provides a granite curbstone paving vehicle and a paving method thereof, the purpose of which is to:
