Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, specifically to an anti-settlement roadbed structure for municipal road engineering. Background Technology

[0002] A roadbed is the foundation of a railway track or road surface, a geotechnical structure formed through excavation or filling. The main function of a roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track, locomotives, rolling stock, road surface, and traffic loads. It also transfers and diffuses the loads deep into the ground. In longitudinal section, the roadbed must ensure the required elevation of the line; in horizontal section, the roadbed connects with bridges and tunnels to form a complete and continuous line. In civil engineering, the roadbed plays a crucial role in terms of construction volume, land area, and investment. The roadbed structure includes embankments filled with natural soil and stone and road cuts excavated from natural strata. It directly supports the track and bears the loads of passing trains, forming the main body of the roadbed. To enhance pedestrian comfort, a layer of plastic granules is usually laid on the top layer of municipal park roads during construction.

[0003] However, existing municipal park roadbed structures allow rainwater to indirectly infiltrate into the ground through the subgrade structure during drainage, resulting in weak drainage capacity and low drainage efficiency. During heavy rain, rainwater accumulates on the road surface, causing inconvenience to pedestrians. Therefore, this does not meet the current requirements. To address this, we propose an anti-settlement subgrade structure for municipal road engineering. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-settlement roadbed structure for municipal road engineering, so as to solve the problem mentioned in the background art that when the roadbed structure of municipal park roads is drained, rainwater indirectly infiltrates into the ground through the roadbed structure, resulting in weak drainage capacity and low drainage efficiency, and rainwater will accumulate on the road surface during rainy weather, causing inconvenience to pedestrians.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a settlement-resistant roadbed structure for municipal road engineering, comprising a lime-sand-gravel rammed earth layer:

[0006] A cushion layer is laid on top of the lime-sand-gravel rammed earth layer. A water control pile pipe is installed inside the lime-sand-gravel rammed earth layer. A connecting sleeve is installed at the upper end of the water control pile pipe by thread. An anti-settlement connecting boss is provided at the upper end of both the water control pile pipe and the connecting sleeve. An anti-settlement connecting rod is fixedly installed inside the anti-settlement connecting boss.

[0007] The natural seepage hole is located at the lower end of the outside of the water control pile pipe. A drain pipe is fixedly installed on the outside of the water control pile pipe, and a municipal underground drainage pipe is fixedly installed at one end of the drain pipe.

[0008] Preferably, a water filter cap is installed at the upper end of the connecting sleeve, and the water filter cap is connected to the connecting sleeve by a thread.

[0009] Preferably, the upper end of the filter cap is provided with a maintenance and disassembly groove.

[0010] Preferably, a cement stabilizing layer is laid on the upper end of the cushion layer.

[0011] Preferably, a surface layer is laid on the upper end of the cement-stabilized layer, and a plastic layer is laid on the upper end of the surface layer.

[0012] Preferably, the anti-settlement connecting boss is fixedly connected to both the water control pile pipe and the connecting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model can increase the contact area between the roadbed and the soil in nature by installing water control piles, thereby playing a certain role in resisting settlement. Installing anti-settlement connecting rods can make the roadbed more stable, make the stress between various parts of the roadbed more uniform, avoid roadbed settlement, effectively extend the service life of the roadbed, and set natural seepage holes to allow rainwater to quickly penetrate through the roadbed and the soil in nature below the roadbed, thereby improving the drainage capacity of the roadbed.

[0015] 2. This utility model, by installing drainage pipes and municipal underground drainage pipes, enables rainwater to be quickly discharged from the roadbed during heavy rain, reducing the drainage pressure on the roadbed, preventing the roadbed from being soaked by rainwater, protecting the roadbed, and avoiding rainwater accumulation on the road surface that would cause inconvenience to pedestrians. The installation of filter caps can filter rainwater, prevent debris from clogging the water control pile pipes, and ensure the rapid discharge of rainwater. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 One embodiment of this utility model is a settlement-resistant roadbed structure for municipal road engineering, comprising a lime-sand-gravel rammed earth layer 1.

[0023] Subbase 2 is laid on top of lime-sand-gravel rammed earth layer 1. Water control pile pipe 6 is installed inside lime-sand-gravel rammed earth layer 1. Installing water control pile pipe 6 can increase the contact area between the roadbed and the soil in nature, thereby playing a certain role in resisting settlement. The upper end of water control pile pipe 6 is connected to connecting sleeve 10 by thread. The upper ends of water control pile pipe 6 and connecting sleeve 10 are both provided with anti-settlement connecting boss 12. Anti-settlement connecting rod 13 is fixedly installed inside the anti-settlement connecting boss 12. Installing anti-settlement connecting rod 13 can make the roadbed more stable, make the stress between various parts of the roadbed more uniform, avoid roadbed settlement, and effectively extend the service life of the roadbed.

[0024] Natural seepage holes 7 are located at the lower end of the outside of the water control pile pipe 6. The natural seepage holes 7 allow rainwater to quickly penetrate through the roadbed and the soil in nature below the roadbed, improving the drainage capacity of the roadbed. A drain pipe 8 is fixedly installed on the outside of the water control pile pipe 6. A municipal underground drainage pipe 9 is fixedly installed at one end of the drain pipe 8. The installation of the drain pipe 8 and the municipal underground drainage pipe 9 allows rainwater to be quickly discharged through the drain pipe 8 and the municipal underground drainage pipe 9 during heavy rain, reducing the drainage pressure of the roadbed on rainwater, preventing the roadbed from being soaked by rainwater, protecting the roadbed, and avoiding rainwater accumulation on the road surface, which would cause inconvenience to pedestrians.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A filter cap 11 is installed at the upper end of the connecting sleeve 10. The filter cap 11 is connected to the connecting sleeve 10 by threads. The filter cap 11 can filter rainwater to prevent debris from clogging the water control pile pipe 6 and ensure the rapid discharge of rainwater. The upper end of the filter cap 11 is provided with a maintenance and disassembly groove 14. A cement stabilizing layer 3 is laid on the upper end of the cushion layer 2. A surface layer 4 is laid on the upper end of the cement stabilizing layer 3. A plastic layer 5 is laid on the upper end of the surface layer 4. The anti-settlement connecting boss 12 is fixedly connected to the water control pile pipe 6 and the connecting sleeve 10.

[0026] Working principle: Workers assemble and install the water control pipe 6 and the drainage pipe 8, connecting the drainage pipe 8 to the municipal underground drainage pipe 9. Next, workers backfill and compact the soil, then lay a lime-sand-gravel rammed earth layer 1 on top of the backfill. Next, the connecting sleeve 10 is threaded onto the upper end of the water control pipe 6, and the anti-settlement connecting rod 13 is installed inside the anti-settlement connecting boss 12. Then, the workers lay the bedding layer 2 and repeat the above operations. The connecting sleeve 10 is then threaded onto the upper end of the water control pipe 6, and the anti-settlement connecting rod 13 is installed inside the anti-settlement connecting boss 12. This process is repeated, first installing the connecting sleeve 10 and the anti-settlement connecting rod 13, then laying the cement stabilization layer 3, and finally installing the filter cap 11 on the upper end of the connecting sleeve 10. Finally, the surface layer 4 and the plastic layer 5 are laid to complete the construction. When it rains, rainwater is filtered through the filter cap 11 and enters the water control pipe 6, directly draining into the deep soil layer. Water seeps into the ground. When the rainfall is heavy, the rainwater will be discharged into the municipal underground drainage pipe 9 through the drain pipe 8. The installation of the water control pile pipe 6 in this structure can increase the contact area between the roadbed and the soil in nature, thereby playing a certain role in resisting settlement. The installation of the anti-settlement connecting rod 13 can make the roadbed more stable, make the stress between various parts of the roadbed more even, avoid roadbed settlement, and effectively extend the service life of the roadbed. The setting of natural seepage holes 7 can allow rainwater to quickly penetrate through the roadbed and the soil in nature below the roadbed, improving the drainage capacity of the roadbed. The installation of the drain pipe 8 and the municipal underground drainage pipe 9 can allow rainwater to be discharged quickly through the drain pipe 8 and the municipal underground drainage pipe 9 during heavy rain, reducing the drainage pressure of the roadbed on rainwater, preventing the roadbed from being soaked by rainwater, protecting the roadbed, and preventing rainwater from accumulating on the road surface and causing inconvenience to pedestrians. The installation of the filter cap 11 can filter the rainwater, prevent debris from clogging the water control pile pipe 6, and ensure the rapid discharge of rainwater.
