A first inclined block side slurry walking groove 22 is provided on the side of the first inclined block 2 away from the first vertical backrest 1, and a second inclined block side slurry walking groove 52 is provided on the side of the second inclined block 5 away from the second vertical backrest 4. The angle between the outer wall of the first inclined block 2 and the horizontal plane is an acute angle, and the angle between the outer wall of the second inclined block 5 and the horizontal plane is an obtuse angle.

[0039] The above-mentioned assembled curb foundation and backrest device are alternately connected to each other through type A devices and type B devices, and the curb is installed and laid inside the type A devices and type B devices, and then the first bottom plate slurry groove 31, the second bottom plate slurry groove 61, the first inclined block side slurry groove 22 and the second inclined block side slurry groove 52 are filled with slurry, which ensures that the curb is laid neatly, installed firmly, and has good integrity with the road foundation. The curbs are tightly connected and not easily damaged.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, a first inclined block 2 is provided with a first inclined block side lifting groove 21, and the first inclined block side lifting groove 21 and the first inclined block side slurry groove 22 are located on the same side of the first inclined block 2, and a first backrest side lifting groove 11 is provided on the first vertical backrest 1, and the first backrest side lifting groove 11 is located on the side of the first vertical backrest 1 away from the first inclined block 2, and the first inclined block side lifting groove 21 and the first backrest side lifting groove 11 are used to lift the A-type device to the designated position using a transport tool before laying the curb.

[0041] like Figure 3 and Figure 4 As shown, in this embodiment, a second oblique block 5 is provided with a second oblique block side lifting groove 51, and the second oblique block side lifting groove 51 and the second oblique block side slurry groove 52 are located on the same side of the second oblique block 5, and a second backrest side lifting groove 41 is provided on the second vertical backrest 4, and the second backrest side lifting groove 41 is located on the side of the second vertical backrest 4 away from the second oblique block 5, and the second oblique block side lifting groove 51 and the second backrest side lifting groove 41 are used to lift the B-type device to the designated position using a transport tool before laying the curb.

[0042] like Figure 1 and Figure 3 As shown, in this embodiment, the cross-sections of the A-type device and the B-type device are both in a concave shape, which helps to lay the curbstones into the A-type device and the B-type device, and to lay the curbstones neatly.

[0043] like Figure 1 and Figure 3 As shown, in this embodiment, a plurality of first inclined block side slurry grooves 22 are evenly distributed on the first inclined block 2, and a plurality of second inclined block side slurry grooves 52 are evenly distributed on the second inclined block 5. The device is cast and fixed by filling the first inclined block side slurry grooves 22 and the second inclined block side slurry grooves 52 with slurry.

[0044] like Figure 1 and Figure 3 As shown, in this embodiment, a plurality of first inclined block side slurry grooves 22 are provided on the first inclined block 2, and the plurality of first inclined block side slurry grooves 22 are evenly distributed, and a plurality of second inclined block side slurry grooves 52 are provided on the second inclined block 5, and the plurality of second inclined block side slurry grooves 52 are evenly distributed, and the curb is fixedly laid by filling the first bottom plate slurry grooves 31 and the second bottom plate slurry grooves 61 with slurry.

[0045] like Figure 1 , Figure 3 and Fig. 9 As shown, in this embodiment, both the type A device and the type B device are made of concrete, the first inclined block 2 is inclined toward the side away from the first vertical backrest 1, and the second inclined block 5 is inclined toward the side close to the second vertical backrest 4. In this embodiment, the angle α between the inner wall of the first inclined block 2 and the first bottom plate 3 is 96°, but the specific inclination angle can be appropriately adjusted according to the on-site use and installation conditions. Similarly, the angle between the inner wall of the second inclined block 5 and the second bottom plate 6 can also be appropriately adjusted according to the on-site use and installation conditions. The purpose of inclined setting of the first inclined block 2 and the second inclined block 5 is to alleviate the cracks caused by stress concentration after the type A device and the type B device are installed on the curb.

[0046] like Figure 1 to Figure 14 As shown, in this embodiment, firstly, according to the size of the assembled base blocks and curbs used in the construction, the road width, and the requirements of the exposed width of the curbs, type A devices and type B devices that meet the road requirements are prefabricated. After the road assembled base blocks are installed, the type A device is hoisted to the position where the curbs need to be built through the first inclined block side hoisting groove 21 and the first backrest side hoisting groove 11 by using a hoisting device, and the type B device is hoisted to the position where the curbs need to be built by using a hoisting device through the second inclined block side hoisting groove 51 and the second backrest side hoisting groove 41. Fig.13 and Fig.14As shown, the A-type device and the B-type device are installed alternately, and the first inclined block 2 and the second inclined block 5 are both facing the inside of the road, and the first vertical backrest 1 and the second vertical backrest 4 are both facing the outside of the road. The A-type device and the B-type device are installed alternately to avoid longitudinal through-slits in the road and to cooperate with the assembled base block. When the flatness of the subbase below the first bottom plate 3 and the second bottom plate 6 meets the design requirements, the curbstones are installed inside the A-type device and the B-type device. If the flatness of the subbase does not meet the design requirements, a small amount of fine stone concrete can be filled above the first bottom plate 3 and the second bottom plate 6 to adjust the elevation of the curbstone. When filling the fine stone concrete, care should be taken not to fill the first bottom plate slurry groove 31 and the second bottom plate slurry groove 61 with the fine stone concrete. After the installation of concrete and curbstones is completed, according to the actual situation on site, the connection between type A device and type B device is sealed with cement mortar, and then when the road is grouting, the assembled base block is grouted together with type A device and type B device, and the slurry fills the first inclined block side slurry groove 22, the second inclined block side slurry groove 52, the first bottom plate slurry groove 31 and the second bottom plate slurry groove 61, and the gaps between the curbstones below the top surfaces of type A device and type B device are all filled with slurry, and the gaps between the curbstones and the devices are also all filled with slurry. After the grouting is completed, the road assembled base block, the curbstone and the device are formed as one, and the gaps between the curbstones above the top surfaces of type A device and type B device can be grouted according to the requirements of the site.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
