Description
Technical Field
[0001] The utility model relates to the technical field of road structures, in particular to a residential cement pavement structure. Background Art
[0002] Existing cement concrete roads are generally divided into two types: one is a low-cost, low-strength road constructed from pure cement concrete; the other is a high-cost, high-strength road constructed from reinforced steel. With the rapid development of the automotive industry, trucks are becoming increasingly numerous and heavier, with an increasing number of vehicles carrying loads of over 100 tons on the road. For roads constructed from pure cement concrete, regardless of whether they are reinforced with steel, cement concrete pavements have joints. These joints are weak in bearing pressure and cannot withstand the passage of heavy vehicles. Furthermore, accumulated water can easily cause two panels to detach. As a result, the compressive, seismic, and flexural properties of cement concrete pavement structures are significantly reduced, resulting in a generally short service life. This short service life of roads wastes resources, and repairing or rebuilding roads wastes significant manpower and material resources.
[0003] The cement concrete pavement in the community uses cement concrete as the main material for the surface layer. Cement concrete pavements include plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete and other types of pavements. With the continuous development of existing technologies, the permeability and compressive resistance of concrete pavements have been improved. However, it is found in existing technologies that since the cement pavement layer is relatively fragile, the middle and bottom layers are mostly filled with original soil or gravel. Long-term use will cause the road surface to collapse and deform due to repeated rolling by cars, requiring special personnel for maintenance, which increases the maintenance cost of the community and brings many inconveniences to people. Utility Model Content
[0004] The purpose of this utility model is to provide a community cement pavement structure with more reasonable structural design, ingenious conception, easy processing and operation, low processing cost, high compressive strength, toughness, high stability, safety and reliability, long service life and cost saving.

Therefore, the plain soil backfill base layer can be placed between the first original soil backfill base layer and the second original soil backfill base layer, which can improve the adhesion between the first original soil backfill base layer and the second original soil backfill base layer. The first original soil backfill base layer, the plain soil backfill base layer and the second original soil backfill base layer form the second layer structure of the road, which requires the burial of various pipelines, so it needs to be easy to excavate, the rigidity cannot be too strong, and it has a certain toughness, which can improve the road's ability to resist compression and deformation, and at the same time has a certain viscosity to ensure the integrity of the entire second layer structure; the lime soil cushion layer is achieved by mixing lime and soil in a certain proportion and compacting them in layers. It is the foundation layer of the entire road and provides a cornerstone for road paving.
[0007] The crushed stone mixed with lime load-bearing layer is evenly distributed with load-bearing pipes, and the crushed stone and lime mixture is filled between the load-bearing pipes.
[0008] The cross section of the load-bearing tube is a honeycomb structure.
[0009] Load-bearing tubes are evenly distributed in the crushed stone and ash load-bearing layer, and the crushed stone and white lime mixture is filled between the load-bearing tubes. The cross-section of the load-bearing tubes is made into a honeycomb structure. The set load-bearing tubes can improve the compressive strength of the crushed stone and ash load-bearing layer, and prevent the road surface from being deformed and collapsed due to long-term rolling of heavy objects such as cars. The set load-bearing tubes can improve the compressive strength of the entire road surface, and the cross-section of the load-bearing tubes is made into a honeycomb structure, which can improve the deformation resistance of the entire road surface.

It is safe and reliable to use, and the service life of the road surface is increased, maintenance is reduced, and costs are saved.
[0010] A warning strip is fixedly arranged between the first original soil backfill base layer and the plain soil backfill base layer.
[0011] The warning tape can serve as a reminder to operators during construction. For example, when conducting ground construction, it can prevent operators from digging into various pre-buried pipes and cause potential safety hazards. It protects the personal safety of operators and improves the safety of construction operations.
[0012] A gas pipeline is provided in the second original soil backfill base layer.
[0013] The gas pipeline installed in the second original soil backfill base can provide gas supply to residents in the community and improve the convenience of moving in.
