Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a road structure for a sewage treatment plant area. Background Technology

[0002] The infrastructure of a wastewater treatment plant mainly includes: pretreatment equipment, activated sludge treatment equipment, aeration equipment, coagulant dosing equipment, filter equipment, and disinfection equipment. After being transported to the wastewater treatment plant, wastewater undergoes combined treatment by the aforementioned equipment, followed by further purification before being discharged. The entire wastewater treatment process relies on pipeline transportation.

[0003] The existing roads in wastewater treatment plant areas were not designed with sufficient consideration for the basic requirements of the pipeline network on the road foundation, such as the need for anti-settlement design and leveling of the road foundation. When the road foundation settles, the foundation on which the wastewater pipes are located sinks, causing the wastewater pipes to deform, bend, or even break. Especially when the foundation settles at the connection points of the wastewater pipes, the connection points may detach from the pipe supports on the ground, further increasing the tilting or swinging angle of the wastewater pipes. Ultimately, the two originally connected sections of wastewater pipes may separate, causing the internal wastewater to flow out. This requires re-excavation of the road, increasing the difficulty of maintenance and repair. Furthermore, this situation inadvertently prolongs the overall wastewater treatment process, slows down the progress of wastewater treatment, and increases the cost of wastewater treatment.

[0004] In summary, how to achieve anti-settlement design for the road and pipeline network inside the sewage treatment plant area is one of the urgent problems to be solved in the field of sewage treatment. Utility Model Content

[0005] The purpose of this invention is to provide a road structure for a wastewater treatment plant area to solve the problems existing in the prior art.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] This utility model provides a road structure for a wastewater treatment plant area, comprising:

[0008] The layers are arranged from top to bottom as follows: surface layer, bonding layer, base layer, subbase layer, sand cushion layer, and soil base layer;

[0009] Sewage pipes fixed in the sand cushion layer;

[0010] The first anti-settlement structure fixed on both sides of the sewage pipe;

[0011] A second anti-settlement structure fixed at the lower end of the sewage pipe;

[0012] The third anti-settlement structure is fixed on both sides of the second anti-settlement structure.

[0013] Furthermore, the first anti-settlement structure includes: a horizontal anti-settlement structure, an upper anti-settlement structure located at the center of the upper surface of the horizontal anti-settlement structure, and a plurality of first lower anti-settlement cylinders uniformly distributed at the center of the lower surface of the horizontal anti-settlement structure.

[0014] Furthermore, the upper anti-settlement structure is fixed in the base layer, the horizontal anti-settlement structure is fixed at the junction of the base layer and the sand cushion layer, and the first lower anti-settlement cylinder is fixed in the sand cushion layer.

[0015] Furthermore, the upper anti-settlement structure, the horizontal anti-settlement structure, and the multiple first lower anti-settlement cylinders are an integral reinforced concrete structure.

[0016] Furthermore, the gap between the outer wall of the sewage pipe and the first anti-settlement structure is filled with a rubber layer.

[0017] Furthermore, the second anti-settlement structure includes: an anti-settlement platform and a plurality of second anti-settlement cylinders fixed to the lower surface of the anti-settlement platform; the plurality of second anti-settlement cylinders are arranged in an array uniformly.

[0018] Furthermore, the anti-settlement pier and the multiple second anti-settlement columns are an integral reinforced concrete structure.

[0019] Furthermore, the cross-section of the third anti-settlement structure is T-shaped.

[0020] Furthermore, the T-shaped head of the third anti-settlement structure is fixed in the sand cushion layer, and the T-shaped tail of the third anti-settlement structure is fixed in the soil base layer.

[0021] Furthermore, the bonding layer is prepared using C30 waterproof concrete.

[0022] The beneficial effects of this utility model are:

[0023] This utility model provides a road structure for a sewage treatment plant area. First, an anti-settlement structure consisting of an upper anti-settlement structure, a horizontal anti-settlement structure, and a first lower anti-settlement cylinder is used to design the area around the sewage pipe for anti-settlement. At the same time, a rubber layer is filled between the first anti-settlement structure and the outer wall of the sewage pipe. While achieving anti-settlement through the first anti-settlement structure, the rubber layer can also play a role in isolation, buffering, corrosion resistance, and waterproofing.

[0024] In addition, this utility model also sets a second anti-settlement structure at the bottom of the sewage pipe. The second anti-settlement structure can further buffer the first anti-settlement structure, the sewage pipe and the rubber layer as a whole. In particular, the multiple second anti-settlement cylinders arranged in an array at the bottom can further disperse the load force, stabilize the soil and reduce settlement.

[0025] Meanwhile, in addition to the first and second anti-settlement structures, a third anti-settlement structure with a T-shaped cross-section was designed to stabilize the soil base on both sides of the second anti-settlement structure. This can further enhance the road's load-bearing capacity and improve the overall anti-settlement ability of the road.

[0026] This utility model, through the design of three anti-settlement structures, plays an anti-settlement role and provides a good protection for sewage pipelines, thus ensuring the safe construction and normal operation of road and pipeline networks in sewage treatment plant areas.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, the road structure of a sewage treatment plant area provided by this utility model mainly consists of the following components:

[0034] Surface layer 1, bonding layer 2, base layer 3, subbase layer 4, sand cushion layer 5, soil base layer 6, first anti-settlement structure 7, sewage pipe 8, rubber layer 9, second anti-settlement structure 10, and third anti-settlement structure 12.

[0035] The surface layer 1, connecting layer 2, base layer 3, subbase layer 4, sand cushion layer 5, and soil base layer 6 are arranged sequentially from top to bottom.

[0036] As a preferred embodiment, the surface layer 1 can be prepared using asphalt concrete. Examples include 20mm fine-grained asphalt concrete, 40mm medium-grained asphalt concrete, and 60mm coarse-grained asphalt concrete. However, it is not limited to these.

[0037] In a preferred embodiment, the bonding layer 2 can be prepared using C30 waterproof concrete. The bonding layer 2 strengthens the interaction between the surface layer 1 and the base layer 3, while also reducing the impact of cracks in the base layer 3 on the surface layer 1.

[0038] As a preferred embodiment, the base layer 3 may specifically be cement-stabilized soil, but is not limited thereto.

[0039] As a preferred embodiment, the subbase 4 may specifically be stabilized soil made from lime industrial waste residue, but is not limited thereto.

[0040] In a preferred embodiment, the thickness of the sand cushion layer 5 must be greater than the diameter of the sewage pipe 8.

[0041] The sewage pipe 8 is installed in the sand cushion layer 5, and a first anti-settlement structure 7 is provided on both sides of the sewage pipe 8, that is, a first anti-settlement structure 7 is fixed on each side of the sewage pipe 8. Figure 2As shown, the first anti-settlement structure 7 mainly consists of an upper anti-settlement structure 701, a horizontal anti-settlement structure 702, and a first lower anti-settlement cylinder 703. The upper anti-settlement structure 701 is located at the center of the upper surface of the horizontal anti-settlement structure 702. The number of first lower anti-settlement cylinders 703 can be multiple, depending on the actual engineering construction situation. Multiple first lower anti-settlement cylinders 703 are evenly distributed at the center of the lower surface of the horizontal anti-settlement structure 702. The upper anti-settlement structure 701, the horizontal anti-settlement structure 702, and multiple first lower anti-settlement cylinders 703 are an integral reinforced concrete structure. The upper anti-settlement structure 701 is fixed in the base layer 4, while the horizontal anti-settlement structure 702 is fixed at the junction of the base layer 4 and the sand cushion layer 5 (for example, the upper half of the horizontal anti-settlement structure 702 is fixed in the base layer 4, and the lower half is fixed in the sand cushion layer 5). The first lower anti-settlement cylinders 703 are fixed in the sand cushion layer 5, and the first lower anti-settlement cylinders 703 can be directly fixed to the second anti-settlement structure 10. The sewage pipe 8 is installed between the two symmetrical first anti-settlement structures 7, and the gap between the outer wall of the sewage pipe 8 and the first anti-settlement structure 7 is filled with a rubber layer 9. The rubber layer 9 prevents direct contact between the first anti-settlement structure 7 and the outer wall of the sewage pipe 8, and effectively protects the sewage pipe 8 by providing buffering, corrosion resistance, and waterproofing. Because the T-shaped structure formed by the upper anti-settlement structure 701 and the horizontal anti-settlement structure 702 at the upper end of the first anti-settlement structure 7 acts like a cantilever retaining wall, the soil on both sides of the upper anti-settlement structure 701 is separated by the upper and horizontal anti-settlement structures 701 and 702, thereby constraining the soil on both sides of the upper anti-settlement structure 701, reducing soil settlement, and playing an anti-settlement role. At the same time, multiple lower anti-settlement cylinders 703 set at the lower end of the first anti-settlement structure 7 are evenly distributed at intervals, sharing the load with the upper anti-settlement structure 701 and the horizontal anti-settlement structure 702 at the upper end, further enhancing the anti-settlement performance.

[0042] A second anti-settlement structure 10 is fixed at the lower end of the sewage pipe 8, and the second anti-settlement structure 10 is installed as a whole in the soil base layer 6. For example... Figure 3 As shown, the upper end of the second anti-settlement structure 10 is an anti-settlement platform, and the first lower anti-settlement column 703 can be directly fixed to the anti-settlement platform. Multiple second anti-settlement columns 11 are fixed to the lower end of the anti-settlement platform. The anti-settlement platform and the multiple second anti-settlement columns 11 are an integral reinforced concrete structure. These second anti-settlement columns 11 are arranged in a uniform array. This structural form can further disperse the load force, stabilize the soil, and reduce settlement. The number of second anti-settlement columns 11 can be designed according to actual needs.

[0043] In addition, to further reduce soil settlement, third anti-settlement structures 12 are symmetrically installed on both sides of the second anti-settlement structure 10, meaning that one third anti-settlement structure 12 is fixed on each side of the second anti-settlement structure 10. Figure 4 As shown, the third anti-settlement structure 12 has a T-shaped cross-section and is arranged in a strip shape along the direction of road extension. The third anti-settlement structure 12 is a monolithic reinforced concrete structure. The T-shaped head of the third anti-settlement structure 12 is fixed in the sand cushion layer 5, while the T-shaped tail is entirely fixed in the soil base layer 6. Through the overall structural design of the third anti-settlement structure 12, the overall anti-settlement capacity of the road can be further improved, and its load-bearing capacity can also be enhanced.

[0044] In this utility model, the road construction method and the pipeline installation method can be implemented according to the existing technology.
