Detailed Description

The technical scheme of the utility model is described in detail below through the drawings, but the protection scope of the utility model is not limited to the embodiments.

Examples: the paving structure suitable for the ancient building garden road is applied and constructed in a town of a certain travel in a lake of a salt city, 102 buildings (3-9 m in layer height) of the field green brick archaize building are constructed, water systems and rockery are basically formed, underground comprehensive pipe networks are basically constructed, and paving construction is needed.

A pavement structure suitable for a road is built to ancient times, includes: a plain soil layer 1, a broken stone cushion layer 2, a concrete cushion layer 3, a cement mortar combination layer 4 and an old green brick layer 5 which are paved from bottom to top in the roadbed, as shown in figure 1.

The gravel cushion layer 2 is a graded gravel cushion layer 2, the thickness is 100mm, the graded gravel cushion layer is composed of gravels with different particle sizes, and compared with the gravel cushion layer 2 with single particle size, the compactness of the graded gravel cushion layer 2 is better. Meanwhile, the material has good water permeability, diffusion stress and bearing transition effect, and the material source is wide, can be obtained locally, is convenient for processing raw materials and mixtures, and is easy for mechanical paving operation. The pavement structure strength can be enhanced, and the water-proof and drainage functions of the pavement structure are considered.

The thickness of the concrete cushion layer 3 is 100mm, the foundation bearing capacity of the pavement structural layer can be obviously enhanced through the arrangement of the concrete cushion layer 3, and the common quality common diseases such as road collapse, uneven settlement and the like can be effectively prevented and treated in the process due to the fact that many tourists in the ancient architecture garden scenic spot are considered, and the foundation is firm under the long-acting use of pavement.

The old green bricks with the specification of 240 multiplied by 115 multiplied by 53mm are used as paving surface layers, and the arrangement modes of the old green bricks comprise a basket bed and a herringbone bed, as shown in figures 2 and 3. The old green bricks can be laid vertically, the thickness is 115mm, the bearing capacity is stronger, and the wear resistance is better. The visual effect of the brick floor is consistent with that of peripheral brick mixed structure houses, corridor frames, pavilions and the like through old brick floors. The periphery of the old green brick layer can adopt an old green brick whole brick edge 61, as shown in fig. 4; or an old green brick half brick edge 62 is used, as shown in fig. 5; or with granite trim 63 as shown in fig. 6.

The cement mortar bonding layer 4 adopts 1:3 dry hard cement mortar, and the whole thickness is 30mm.

As shown in fig. 7, the construction process of the paving structure includes the following steps:

s1, excavating a roadbed and tamping plain soil

The excavation depth is determined according to the design profile, and the excavator is adopted to perform excavation in cooperation with manual work in the embodiment. 10cm of soil is reserved at the bottom of the foundation trench, the foundation trench is manually excavated to the designed elevation, and the compaction degree is more than or equal to 93%.

S2, paving a macadam cushion layer 2:

the graded broken stone with corresponding thickness is paved, the bottom surface of the broken stone foundation is paved on the same elevation, for example, when the depths are different, the paved broken stone is graded uniformly, and the maximum stone particle size is not more than 2/3 of the paving thickness and not more than 50mm. If the phenomenon of stone piling is found, the stones at the positions should be dug out and respectively filled with graded broken stone.

S3, pouring a concrete cushion layer 3:

and pouring a 10cm C20 concrete cushion layer according to design requirements, pumping concrete, and mechanically vibrating, wherein a pump pipe of a conveying pump is required to directly extend into a foundation due to small thickness so as to ensure that the free falling height of the concrete is not more than 2m. After the concrete is formed, the surface is covered with water for curing in order to reduce the temperature difference between the inside and the outside of the large-volume concrete.

The template adopts a wood template, and the template is clean, smooth and tight in joint when being erected, and is firmly supported, and the joint of the template adopts a sponge system so as to prevent the slurry leakage and the die leakage during pouring. The internal and external supports of the template are made of square timber, so that the disassembly is convenient.

S4, paving a surface layer:

(1) Leveling and snapping lines: and controlling the near-index height and the plane axis in the point according to the elevation of the design drawing. Before each 5m multiplied by 5m square is paved, a standard brick is paved at four corners according to the position and the elevation, and a standard brick is paved at the south and the north on the basis. After measurement and inspection, the elevation and the position are correct, and then large-area paving is performed.

(2) Trial assembly and trial arrangement: and before paving, performing trial assembly on each old green brick according to azimuth and angle. After trial assembly, the assembly is numbered and arranged in two directions, and then the assembly is orderly arranged according to the numbers. To check the gaps between the panels, it is checked whether the panel positions are in line with the design drawing. And before formal paving, performing trial discharge once.

(3) Paving a surface layer: and (3) retesting the elevation of the finished surface after the paving is finished according to a herringbone paving or a basket paving by adopting a main material specification of 240 multiplied by 115 multiplied by 53mm of a bluestone brick.

(4) Sweeping: after the paving is finished, the middle coarse sand is used for sweeping the joints, the sand consumption is noted, and excessive sand is avoided.

(5) And (5) cover maintenance: after the seam sweeping is completed for 24 hours, geotextile or clean straw is used for covering, so that the damage of a finished product is avoided; pedestrians are prohibited for 2 days.

S4, edge folding: and (3) selecting the old green brick whole brick, the old green brick half brick or the granite to be folded, wherein the basic practice is the same as a main pavement foundation (comprising a plain soil layer 1, a broken stone cushion layer 2, a concrete cushion layer 3 and a cement mortar combined layer 4), and the plain soil layer 1, the broken stone cushion layer 2 and the concrete cushion layer 3 on the outer side of the folded edge are expanded by 8-10 cm than the surface layer.

The ancient building garden road paved by the construction method can effectively release the integral ancient building garden engineering, and avoid the phenomenon of uncoordinated atmosphere between the road and surrounding buildings. Meanwhile, the road structure layer and the surface layer of the system have strong bearing capacity, good folding resistance and skid resistance, are difficult to damage and replace, so that the post-operation management of a park is convenient and efficient, and the system has good ornamental and practical values.

As described above, although the present utility model has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the utility model itself. Various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
