It does not contain fine aggregate. Pervious concrete is formed by the mutual adhesion of a thin layer of cement paste on the surface of coarse aggregate, resulting in a honeycomb structure with uniformly distributed pores. It has the characteristics of air and water permeability and light weight. Pervious concrete is often used in road construction. Pervious concrete is laid on the road surface and needs the assistance of a roller paving device.

DETAILED DESCRIPTION

[0031] The embodiments of the present application are described in detail below in combination with the drawings, but the present application can be implemented in multiple different ways as defined and covered below.

[0032] As Figure 1 and Figure 2As shown, the pervious concrete paving device of the embodiment comprises a rack 100, a rolling mechanism 200 and a leveling mechanism 300 installed on the rack 100, the rack 100 is used to provide stable support across the two sides of the surface to be paved and move along the paving direction of the concrete. By installing the rolling mechanism 200 and the leveling mechanism 300 on the rack 100, the rack 100 stably supports the rolling mechanism 200 and the leveling mechanism 300 above the surface to be paved and drives the rolling mechanism 200 and the leveling mechanism 300 to move towards the paving direction of the concrete, so that the device completes the paving of the concrete during walking, ensures the stability of the concrete paving process, is convenient and fast, improves the work efficiency. Preferably, the rack 100 is connected with a driving device, the automatic movement and direction control are realized by controlling the driving device, the intelligent control is realized, manual operation is not needed, time and labor are saved, the paving efficiency is effectively improved, and the labor intensity and workload are greatly reduced.

[0033] As shown in Figure 1 and Figure 2 The rolling mechanism 200 comprises a rolling part 201 and a lifting part 202, the rolling part 201 is arranged at the lower end of the rack 100 to roll the concrete, and the lifting part 202 is installed on the rack 100 to control the lifting of the rolling part 201. Thus, the rolling mechanism 200 sets the rolling part 201 as a liftable part through the lifting part 202, which not only can roll the concrete, but also can adjust the rolling degree to a suitable range to achieve the best compaction effect, has good paving effect, and can adjust the distance between the rolling part 201 and the surface to be paved through the lifting part 202 to control the paving thickness of the concrete, so as to meet different paving thickness requirements, has high flexibility, improves the adaptability of the device to on-site construction, and enhances the practicality.

[0034] As shown in Figure 1 and Figure 2As shown, the flattening mechanism 300 is mounted on the frame 100, and in this embodiment, the flattening mechanism 300 is arranged on the side of the rolling member 201 facing the concrete paving direction to push and pre-level the concrete before the rolling member 201 rolls on the concrete, while preventing the concrete from leaking from the side of the paving surface. Alternatively, since the rolling member 201 and the support 102 can move along the length direction of the paving surface, the flattening mechanism 300 can be arranged on both sides of the rolling member 201 to enable the flattening mechanism 300 to perform flattening operation in both directions without reversing the support 102, thereby enhancing the flexibility of the device and expanding the application range. By pre-flattening the concrete in front of the rolling mechanism 200 through the flattening mechanism 300, the concrete poured on the ground can be uniformly spread to prevent the unevenness of the concrete surface caused by the accumulated concrete in local area, so that the concrete is uniformly spread and the thickness of the concrete layer is consistent everywhere to ensure the flatness of the paving surface. In addition, the flattening mechanism 300 can also gather the concrete at the side of the paving surface and guide the concrete on both sides of the flattening mechanism 300 to prevent the concrete from leaking from the side during the initial gathering process, so that the concrete is always within the gathering range of the flattening mechanism 300, without the need to re-level the concrete, thereby greatly reducing the workload and improving the paving efficiency.

The connecting block 2013 is arranged on both sides of the groove 1011 of the mounting plate 101 and is slidingly arranged in the groove 1011 in the height direction, so that the connecting block 2013 can drive the compression roller 2011 to lift to adjust the distance between the compression roller 2011 and the surface to be paved, so as to adjust the rolling degree of the concrete and meet the demand of different paving thickness of the concrete. Preferably, the length of the compression roller 2011 is not less than the width of the surface to be paved, so as to ensure that the compression roller 2011 can roll and compact the concrete in the range of the surface to be paved. Alternatively, a plurality of compression rollers 2011 can be arranged, and the plurality of compression rollers 2011 are arranged in the length direction of the surface to be paved and movably arranged in the connecting block 2013 through the connecting shaft 2012, so as to increase the rolling range of the concrete and further enhance the rolling effect of the concrete.

Preferably, in this embodiment, the fixed block 301 is arranged on one side of the mounting plate 101. When in use, the fixed block 301 is arranged towards the laying direction of the concrete, so that the concrete can be pre-spread by the spreading plate 302 before the rolling element 201 rolls the concrete, thereby uniformly spreading the concrete poured on the ground, preventing the unevenness of the concrete surface caused by the accumulation of concrete in some parts, making the concrete spread uniformly and the thickness of the concrete layer consistent, and ensuring the flatness of the spread pavement. At the same time, the baffle 303 can gather and guide the concrete on both sides of the spreading plate 302, limiting the concrete within the range of the spreading plate 302, preventing the concrete from leaking from the side during the initial gathering of the concrete, ensuring that the concrete is always within the gathering range of the spreading mechanism 300, and reducing the workload and improving the spreading efficiency.
