[0028] The width of the ash soil layer 4 is greater than the width of the base concrete layer 1 , and the base concrete layer 1 is provided with curbs 2 made of a plurality of concrete blocks 21 on both sides in the width direction.
[0029] like Figure 2As shown, the curb 2 of this embodiment is located on the lime soil layer 4. The two sides of the lime soil layer 4 respectively extend beyond the two curbs 2 by a partial width, and the partial widths by which the two sides of the lime soil layer 4 extend beyond the two curbs 2 are equal.
[0030] As Figure 2 shown, on the partial widths by which the two sides of the lime soil layer 4 of this embodiment respectively extend beyond the two curbs 2, there are lime soil piles 22, and the lime soil piles 22 are piled on the outer side walls of the curbs 2.
[0031] When the asphalt concrete layer is arranged on the upper part of the basic concrete layer 1 of this embodiment, a manhole cover can be covered on the water well, and it can be used as a temporary road.
[0032] As Figure 2 shown, an AC-20C asphalt concrete layer 31 is further arranged on the basic concrete layer 1 of this embodiment. An AC-13 asphalt concrete layer 3 is arranged on the AC-20C asphalt concrete layer 31. The widths of the AC-20C asphalt concrete layer 31 and the AC-13 asphalt concrete layer 3 are both equal to the width of the basic concrete layer 1; the upper end of the water well extends to the upper surface of the AC-13 asphalt concrete layer 3. After the asphalt concrete layer is laid, it can be used as a formal road.
[0033] Optionally, the thickness of the AC-13 asphalt concrete layer 3 of this embodiment is 30 - 50 mm, and the thickness of the AC-20C asphalt concrete layer 31 is 50 mm - 70 mm.
[0034] Preferably, the thickness of the AC-13 asphalt concrete layer 3 is 40 mm, and the thickness of the AC-20C asphalt concrete layer 31 is 60 mm.
[0035] Optionally, the basic concrete layer 1 is a C30 concrete layer.
[0036] Optionally, the thickness of the basic concrete layer 1 is 150 mm - 250 mm.
[0037] Optionally, the thickness of the lime soil layer 4 is 200 mm - 300 mm, preferably 250 mm, the lime-soil ratio is 3:7, and the compaction coefficient ≥ 0.97; the width of the expansion joint 12 is 8 mm - 12 mm. The lime soil layer is arranged on a rammed plain soil foundation, and the compaction coefficient of the rammed plain soil foundation ≥ 0.94.
[0038] Specifically, as Figure 1 shown, the water well includes a rainwater well 7 and a sewage well 6. The pipelines include a rainwater pipe 71 and a sewage pipe 61. The lower ends between adjacent rainwater wells 7 are communicated through the rainwater pipe 71, and the lower ends between adjacent sewage wells 6 are communicated through the sewage pipe 61.
[0039] In the construction preparation stage of the temporary and permanent combined construction road structure of this embodiment, construction drawings of outdoor pipe networks, construction roads, and landscape gardens are obtained. Plan layout drawings for each stage are drawn based on the construction drawings. Design optimization is carried out according to the plan layout drawings in combination with the construction drawings of outdoor pipe networks, construction roads, and landscape gardens, and the design unit is communicated with for drawing change adjustment. The outdoor pipe network is constructed first, and temporary sleeves are arranged in advance at positions where pipelines cannot be embedded temporarily. The underground pipe network, the compaction of the original soil subgrade of the road surface, the construction of the 3:7 lime soil base layer of the road surface, and the construction of the concrete base layer of the road surface are constructed in sequence according to the adjusted plan layout drawings, and the asphalt mixture surface layer is reserved for construction in the landscape garden stage. Specifically, a 200-mm-thick C30 concrete base layer is poured on the lime soil layer first, and this base layer serves as the temporary road surface layer. A 10-mm-wide expansion joint is set every 6 m on the road, and the expansion joint is treated with asphalt rubber caulking. After the construction of the temporary road is completed and after it is used as a temporary road, the concrete base layer can be cleaned, and a 60-mm-thick AC-20C ordinary asphalt concrete surface layer is paved. After the maintenance period ends, a 40-mm-thick AC-13 ordinary asphalt concrete is continued to be paved as the final surface layer.
[0040] For the temporary and permanent combined construction road structure of this embodiment, by embedding pipelines and setting up water wells, this construction road structure can be used as a temporary road for building construction, and after the building construction is completed, asphalt concrete can be laid as a permanent road structure without damaging the temporary road structure; it can not only meet the requirements of the design drawings but also meet the foundation bearing capacity requirements when various heavy vehicles pass during the construction stage, solving problems such as the need to break the concrete temporary road and transport the concrete fragments out of the site and re-construct the field pipe network and the formal road during later garden construction, resulting in waste of materials and human resources. Through the practice of combining temporary and permanent construction roads, not only is the construction procedure simplified, the construction time in the landscape garden stage is shortened, but also the construction investment is reduced, greatly improving the outdoor construction efficiency, having a positive impact on the overall project, shortening the construction period at the same time, enabling the construction unit to put it into use and operation in advance, and maximizing the benefits.
