Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of base structure construction, in particular to a cement stabilized macadam base and a construction method thereof. BACKGROUND

[0002] The cement stabilized macadam base is the core load-bearing structure of road engineering, which forms an integral stress system through cementing the macadam particles to provide stable support for the pavement and directly determines the bearing capacity and service life of the road. If the base structure has insufficient strength or poor stability, diseases such as rutting, cracking and settlement are likely to occur, which leads to pavement damage and increases maintenance costs. In road construction, the base structure needs to withstand the dual action of vehicle load and environmental factors. The traditional cement stabilized macadam base generally relies solely on the cemented macadam structure, which has weak crack resistance and deformation resistance, and is prone to cracking due to load accumulation or temperature stress over a long period of use. Although some base structures have added geocells to improve the overall performance, the geocells and the macadam base structure lack sufficient fixation, which makes them prone to displacement during the compaction process and fails to fully enhance the effect. At the same time, temperature control is difficult during the maintenance process of the base structure, which restricts the improvement of road construction quality.

[0003] When the temperature difference is large, temperature stress is likely to occur inside the base structure, which accelerates the development of cracks and makes it difficult to meet the requirements of road engineering. SUMMARY

The method of claim 9, wherein the cement-stabilized aggregate base is constructed by: It includes the following steps: S1, when the base structure (100) is constructed, the new geocell (500) is spread by unfolding the cell strip (501) in sequence and laying it on the base structure (100) according to the distance between the two curb structures (200), after the new geocell (500) is spread, the side stop (400) is arranged on both sides of the new geocell (500), and one end of the outer clamping structure (503) and the inner clamping structure (502) is exposed outside through the reserved joint (401); S2, after the side stop (400) is laid, the space enclosed between the side stop (400) and the curb structure (200) is filled with the mixture of gravel and steel fiber (300), and the mixture of gravel and steel fiber (300) covers the new geocell (500); S3, after the mixture of gravel and steel fiber (300) is filled, the mixture of gravel and steel fiber (300) is compacted, and the upper cover (5041) is pressed during the compaction process, so that the upper cover (5041) presses the fixing nail (5042) downward, the fixing nail (5042) drives the spiral thread (5045) to rotate in cooperation with the spiral groove (5044), so that the fixing nail (5042) is drilled into the base structure (100) for positioning and reinforcing; S4, after compaction, the side stop (400) on one side is removed, and the new geocell (500) is laid again to connect the two new geocells (500), and the construction work is continued according to the above steps; S5, when the stage maintenance is needed, the temperature control equipment is connected with the inner clamping structure (502), so that the temperature control equipment adjusts the temperature through the inner clamping structure (502), and the uniform temperature maintenance work is carried out through the heat conduction strip (505).
